Thigh muscle exercises are beneficial for knee condition patients

Updated review of studies needed

Patellofemoral pain syndrome (PFPS) is one of the most commonly reported injuries in the field of sports medicine. The condition is most prevalent in runners and active individuals, and individuals who have it experience pain behind and around the kneecap that tends to get worse with squatting, prolonged sitting and stair activities. Treatment for PFPS typically consists of physical therapy, with a focus on exercises that strengthen the quadriceps muscles in the front of the thigh. This type of intervention is popularly used, but evidence to support its effectiveness is not very strong. The last review of studies on the topic was in 2003, and it only found little evidence that these exercises were effective for PFPS. For this reason, an updated review of the available literature-which is called a systematic review-was conducted, with the aim of determining the true effectiveness of quadriceps-strengthening exercises for PFPS patients.

Researchers perform a search of three databases for appropriate studies

To conduct the review, researchers performed a search of three major medical databases. They were specifically looking for high-quality studies called randomized-controlled trials (RCTs) that evaluated the effects of quadriceps-strengthening exercises for PFPS. RCTs randomly assign patients to various treatment groups and are considered the gold standard for determining whether an intervention works or not. This search led to seven RCTs being included: three RCTs on 204 participants investigated quadriceps-strengthening exercises alone, while five RCTs on 422 participants investigated quadriceps-strengthening exercises combined with other interventions. Once gathered, the researchers reviewed the findings of these RCTs and compared them to one another. The quality of all included studies was also assessed in order to gauge how reliable their results were.

Quadriceps-strengthening exercises alone and in combination reduce pain and improve function

On the whole, results were supportive of quadriceps-strengthening exercises for PFPS patients, both alone and when combined with other exercises. It was found that when they were performed alone, these exercises were more effective for reducing pain and improving function in patients when compared with advice and information alone. When combined with other interventions-such as hip-strengthening exercises, stretching, kneecap taping and home exercises-these exercises were also found to reduce pain for up to 12 months; however, they did not appear to improve function. This lack of improvement may be due to patients self-reporting their function scores, which has a margin for error. Nonetheless, the findings of this systematic review clearly show that quadriceps-strengthening exercises are beneficial to individuals with PFPS, whether used on their own or combined with other interventions. Based on this, patients currently dealing with pain that could be PFPS should think about seeing a physical therapist to receive an appropriate treatment program with these components to help them improve quickly and safely.

Pitching consecutive days in youth softball leads to pain & weakness

Popularity of softball is growing rapidly in the U.S.

Fast-pitch softball is one of the most popular and fastest growing sports among youth females, and the number of high school softball players in the U.S. is nearing that of baseball. But there is one major difference between the two sports: the mechanics of pitching a baseball and the impact it has on the body have been thoroughly studied, but research on the mechanics of the windmill pitch in softball is lacking. While it was once believed that the stress placed on the shoulder in softball is less than in baseball, recent studies have suggested that it may be more similar. The number of injuries in fast-pitch softball is also very high, but the details surrounding these injuries are poorly documented. But despite all these signs that the windmill pitching motion in softball is not as safe as previously thought, there are no pitching limitations in fast-pitch softball as there are in baseball. This means that some softball pitchers can pitch multiple games in a single day, up to three days in a row in some cases. Since research is lacking on the impact of pitching so frequently on these young pitchers’ arms, a study was conducted that investigated this effect on strength, fatigue and pain related to windmill pitching in youth softball.

Data collected on youth pitchers participating in 2-day and 3-day tournaments

For the study, researchers collected data on 17 female fast-pitch softball pitchers between the ages of 14-18 years who were participating in 2-day and 3-day weekend tournaments. Before pitching, information was gathered on these participants’ demographics and their history of shoulder injury or pain, as well as any other medical problems that might have had an effect on their ability to pitch. Then, at the start and end of each day of tournament play, these pitchers were assessed for fatigue, pain and strength of the shoulder and elbow in the dominant throwing arm. These values were compared at the end of each day and at the end of the tournament to determine if pitching had a negative effect on their symptoms.

Pain and fatigue are found to gradually increase over the course of the tournament

Of the 17 pitchers studied, eight participated in 3-day tournaments and six participated in 2-day tournaments. These athletes pitched in 1.5 games per day and threw 82 pitches per day, and there was a total exposure of three games pitched and 166 pitches thrown per tournament. Results showed that over the course of an average single day of tournament play, these pitchers had a significant increase in shoulder pain and fatigue, as well as a decrease in their strength. Over the course of the entire tournament, there was an even greater increase in pain and fatigue, as well as a greater decrease in their strength over this period of time. Finally, it was found that these pitchers did not recover to their baseline strength in many of the tested muscle groups by the day following pitching.

How pitch counts and physical therapy can help

These findings clearly show that windmill pitching on consecutive days leads to declines in shoulder and elbow strength that are not recovered the next day, as well as significant increases in pain and fatigue. These changes can lead to shoulder damage and increase the risk for injury in young softball players if they continue to pitch on consecutive days without regulations. This is why it has been suggested that implementing pitch counts similar to those used in baseball may address this potential problem and reduce the likelihood of injury in softball. Another possible solution to go along with pitch counts is to better prepare these young athletes for the demands of their sport with a conditioning training program provided by a physical therapist. Doing so can increase overall fitness levels and build up strength in these players so that their bodies are more capable of handling the impact of pitching regularly over the course of a softball season.

6 weeks of PT leads to improvements for athletes dislocated shoulder

One shoulder dislocation increases the risk of injuring it again in the future

The shoulder is the most frequently dislocated joint in the body, which is mainly due to the difference in size between the large end of the upper arm bone (humerus) and the small space it fits into (glenoid cavity). Shoulder dislocations usually occur after direct trauma or a fall onto an outstretched arm, and these injuries are common in sports like rugby, football, and hockey. Unfortunately, after a first dislocation, the shoulder can become unstable, which increases the chances of another dislocation occurring. This risk is particularly high in younger athletes and those involved in contact sports. Some studies have even suggested that the rate for regular shoulder dislocations is as high as 95% in young athletes who dislocate their shoulder once. These figures show why it’s so important to prevent these injuries from occurring in the first place and rehabilitating them properly when they occur. Physical therapy that focuses on strengthening the shoulder is one of the best ways to accomplish this, but it’s not clear which exercises are most effective towards these goals. Therefore, a study was conducted on the use of elastic bands and other strengthening exercises to improve joint strength in individuals diagnosed with a first-time shoulder dislocation.

Six weeks of therapy are divided into three stages

Researchers identified 12 physically active male athletes who had experienced a first-time shoulder dislocation who fit the necessary criteria to be included into the study. Two weeks after their injury, these participants began a six-week physical therapy rehabilitation program divided into three stages. The first stage consisted of a variety of strengthening exercises that were intended to build strength and control the pain and inflammation from the dislocation. These exercises were performed at a low intensity. The second stage focused on restoring a higher level of muscle strength and also increased flexibility, and the exercises were performed at a slightly higher intensity. The third and final stage focused on further improving endurance, strength and flexibility, and the intensity of the exercises increased even more. All stages of this physical therapy program included a variety elastic resistance bands for building strength in these muscles. Participants were evaluated before the program began and then again after two, four and six weeks for various measures of shoulder strength and flexibility.

Exercise program leads to injured shoulders becoming nearly as capable as uninjured shoulders

Results from the tests performed prior to the physical therapy rehabilitation program revealed that many patients had weakness in a number of their shoulder muscles as a result of pain, swelling and inflammation from the shoulder dislocation. After the six-week exercise program, however, these patients experienced considerable improvements of more than 90%. In fact, these improvements in strength and flexibility were so great that the values between the injured and uninjured shoulders were extremely similar in the final measurements. These findings suggest that a physical therapy rehabilitation program that includes elastic resistance bands and weight machines can be effective for improving strength and flexibility in patients who dislocate their shoulder. Following this type of treatment program after an initial dislocation may in effect reduce the likelihood of the patient experiencing another shoulder dislocation and needing surgery as a result. Therefore, while more research on the topic is needed, patients are strongly encouraged to visit a physical therapist after their first shoulder dislocation for appropriate treatment, as it may save them from additional shoulder injuries in the future.

Mindset can have significant impact on patients with shoulder pain

Recovery rate is low for many of those with condition

Chronic shoulder pain-meaning it has lasted for at least three months-is a very common condition, with a prevalence of up to 67% in some populations. It is also a complex syndrome that features many unanswered questions, which is one reason the recovery rate from it is so low. Statistics show that about 60% of patients with chronic shoulder pain continue to deal with symptoms one year after first noticing it, and this highlights the need for better treatments to address the condition. Current treatments like physical therapy generally help patients in the initial stages of shoulder pain, but are less effective when it progresses into the chronic phase after several months. One reason for this is that psychological factors like depression, anxiety and fear of pain may actually impact the way in which the patient perceives pain and disability. The connection between psychological factors and chronic shoulder pain has been evaluated, but there is still a great deal that needs to be understood. For this reason, a powerful study called a systematic review was conducted to determine the extent that these factors can have on the perception of shoulder pain and what can be done to correct them.

Twenty-seven studies fit the necessary criteria

Researchers performed a search of five major medical databases for studies that investigated patients who had shoulder pain for at least three months. They were particularly interested in studies focusing on the psychological state of these patients and how it affected their pain and/or disability. This search process led to 128 studies being evaluated, and 27 of these fit the necessary criteria to be accepted into the review. Once collected, the findings from these studies were analyzed and compared to one another in order to establish a clearer idea of the connection between psychological factors and chronic shoulder pain.

Patients with positive attitudes about their condition have less pain and disability

The results clearly showed that patients’ attitudes and perceptions had a significant impact on their levels of pain and disability related to their condition. In particular, a strong relationship was identified between high levels of resiliency, confidence and positive expectations regarding recovery with low levels of pain intensity and disability. On the flip side, it was found that high levels of emotional distress, depressive symptoms, anxiety, concerns about surgery and fear of pain were associated with high levels of pain intensity and disability. The reason for these associations is not completely understood, but is believed to result from patients with negative beliefs perceiving their shoulder pain as a threat. In turn, this may lead them to stop using their shoulder and become less physically active, which begins a vicious cycle that only makes their condition and symptoms worse.

How physical therapists can educate and help these patients

These findings suggest that when treating shoulder pain, psychological factors must be taken into consideration and addressed in addition to physical symptoms. Physical therapists can help by identifying these negative factors in patients early on in treatment, and then work to educate and help patients overcome any barriers to success. In doing so, patients will understand their condition more clearly and increase their chances of experiencing a full recovery from shoulder pain. Patients with shoulder pain are therefore encouraged to consult a physical therapist at the earliest signs of shoulder pain for a full-scale evaluation and appropriate treatment program that takes all their physical and psychological symptoms into consideration.

Many patients with no shoulder pain have MRI findings that show tear

Rates of shoulder surgery are increasing, and it may be partially due to MRI results

The labrum is a piece of cartilage shaped like a cup that’s attached to the rim of the shoulder socket. Its function is to secure the shoulder socket and keep the ball of the joint in place during movement, but this cartilage can tear either from an injury or due to the aging process. The result is called a labral tear, which may or may not cause symptoms depending on how severe it is. Labral tears are difficult to diagnose, and the methods used for evaluation like physical exams and MRIs are not very consistent at identifying the injury. Statistics also show that the rate of surgery for labral tears has been increasing over the past decade-especially in middle-aged patients-and that some of them are not experiencing positive outcomes. While it’s not completely clear why this has been occurring, one possible explanation is that more patients are being diagnosed with labral tears on their MRI and then being told to consider surgery. To investigate this matter and develop a better understanding of the connection between MRI results and shoulder symptoms, a study was conducted.

Patients with no shoulder pain undergo MRIs

Middle-aged individuals between ages 45-60 without any shoulder pain were recruited and invited to participate in the study, which led to 53 of them being accepted. All participants underwent a physical examination and were asked a series of questions regarding the use of their shoulder in work or sports. Then, each participant had an MRI of their shoulder and two radiologists evaluated the results. A radiologist is a medical professional trained to interpret the findings of imaging tests like MRIs and X-rays, and in this case, they were not given any information about the study subjects to increase the reliability of their evaluations.

Both radiologists find labral tears in at least half of patients

On the whole, results showed that labral tears were fairly common. The first radiologist interpreted 38 (72%) of the MRIs as containing a labral tear, while the second radiologist found labral tears in 29 patients (55%). Further analysis revealed that the two radiologists had a moderate level of reliability between them, and that there was only one area in which their reliability was poor.

Avoid having an MRI and see a physical therapist instead

These findings show that even in middle-aged patients that have no signs of shoulder pain, labral tears are commonly found on MRIs. The unfortunate result of this fact is that a patient with shoulder pain can be told they have a labral tear and then go on to have surgery to repair it, even though their pain may not be related to the tear. One way to avoid this predicament is to see a physical therapist first for any type of shoulder pain. Physical therapists will usually treat the pain immediately with a comprehensive treatment program and will only prescribe tests like MRIs if they find it to be completely necessary. Following this course will help you work towards getting better right away regardless of what’s causing your shoulder pain and by keeping you out of the operating room for a labral tear that may not be related to your pain.

Hands-on therapy found to be effective for shoulder pain

Long-term computer use can lead to muscle dysfunction and disorder

Approximately 90% of white-collar workers use computers for more than four hours per day. Over time, sitting and working at a computer can lead to a dysfunction of muscle stability and other disorders of the region, which may result in shoulder and neck pain, as well as a decreased threshold for pain. One of the main reasons for shoulder pain is hyperactivity of an upper back muscle called the upper trapezius, which results in decreased control of two other muscles and instability. To treat this muscle instability, several physical therapy interventions may be used, including manual therapy. In manual therapy, the physical therapist performs various manipulations and mobilizations on the painful area in order to bring about tissue changes that will lead to less pain. Manual therapy may, therefore, be helpful for office workers with shoulder pain, and to evaluate this possibility, a study was conducted.

Middle-aged office workers with pain serve as the study group

Individuals between the ages of 30-40 who had shoulder pain and worked on a computer for more than eight hours a day were invited to participate in the study and screened to determine if they were eligible. This process led to 38 individuals who were accepted, and then randomly assigned to either the manual therapy group or the shoulder stabilization exercise group. Both groups underwent treatment during two 40-minute sessions per week for six weeks. In the manual therapy group, the therapist applied manipulations and mobilizations to various muscles in the back, chest, and neck for three minutes each. In the shoulder stabilization group, patients were instructed to perform a series of stretching and strengthening exercises for muscles in the same area. All patients were assessed before and after undergoing treatment for pressure pain threshold (PPT) of certain muscles, which measures the minimum force applied that causes pain.

Manual therapy leads to greater improvements

After completing treatment, participants in both groups experienced significant improvements with an increased PPT of several muscles of the upper back; however, the manual therapy group showed greater PPT improvements in these muscles than the shoulder stabilization group. This is likely due to the pain-relieving properties of manual therapy, as it increases blood flow and decreases the activity of muscles in such a way that it changes the length of tissues and results in less pain. These results show that while both shoulder strengthening exercises and manual therapy appear to be effective for office workers with shoulder pain, manual therapy is even more beneficial for improving their threshold for pain. Individuals currently dealing with this type of pain should, therefore, seek out the services of a physical therapist for appropriate treatment.

Neck exercise more beneficial than physical activity for whiplash

Persistence of symptoms results from both physical and psychological factors

Approximately 50% of people with whiplash-associated disorders (WADs) continue to report neck pain one year after injury, yet despite this prevalence, there is no clear evidence regarding the most effective treatment. Though exercise is considered safe and effective for neck pain, it’s efficacy for WADs specifically is unclear, and the same is true for prescribed physical activity (PPA). In addition, since the persistence of symptoms in WAD patients is due to both physical and psychological factors, a behavioral approach may also be beneficial, but this is not clear either. Based on these shortcomings, a randomized-controlled trial (RCT) was conducted to evaluate the long-term effects of neck-specific exercise on WADs.

Two-year follow-up performed on earlier RCT

The current study was a one- and two-year follow-up on a 2014 RCT. Initially, 216 individuals with grade 2 or 3 whiplash injury were recruited and randomized to the neck-specific exercise (NSE) group, the neck-specific exercise with behavioral approach (NSEB) group or the PPA group, and all interventions spanned 12 weeks. Patients in the NSE group followed a supervised neck-specific exercise program twice a week. At first, this focused on deep cervical muscles, and eventually, more progressive head resistance training was incorporated gradually. The NSEB group received the same treatments plus physical therapist-led behavioral interventions. The PPA group was prescribed general physical activity to be performed independently without any neck-specific exercises. Patients were assessed for pain, disability, functioning and other variables at baseline and then one and two years later.

Positive long-term outcomes reached with neck-specific exercises

In total, 170 patients (79%) completed the one-year follow-up and 123 (57%) completed the two-year-follow-up. At one year, both neck-specific groups displayed more clinically important improvements in pain, disability, and functioning than the PPA group. At two years, the same was true for disability, and there were also clear trends towards greater improvements in all other outcomes as well. The addition of the behavioral approach did not produce any significant differences. This follow-up RCT suggests that neck-specific exercises can lead to improvements in patients with WADs for one or two years, but additional research is needed to confirm these findings with a different study population, longer follow-up and higher retention rates.

Medicare costs for physical therapy are lower

Understanding these costs may help patients spend less on treatment

Low back pain (LBP) is one of the most common of all painful conditions, as up to 36% of the population will experience it at least once every year. For most of these individuals, the first episode of LBP is not the last, and in some cases, the pain can become a long-term problem. This shows just how important it is to utilize effective treatments for LBP. There are numerous treatments available for patients with LBP, but not all lead to the same benefits and some will cost significantly more than others. This means that some patients can be instructed to receive treatments for their LBP that aren’t necessarily the best for them and cost more, simply because that’s what their doctor recommended. In some cases, this could even wind up costing patients more in the process. To develop a clearer idea of the general costs associated with physical therapy and other treatments for LBP, a study was conducted using Medicare data.

Researchers analyze Medicare data over three years

To conduct the study, researchers gathered Medicare data on patients who were diagnosed with LBP for the first time from 2013-2015. They labeled these patients “beneficiaries” and tracked the treatments they received for their first episode of LBP over this period of time, especially focusing on physical therapy, injections, back-related surgery and no treatment. The Medicare costs associated with the treatments these beneficiaries received was then analyzed and compared to determine how expensive each of them was overall.

Medicare spending for patients who received physical therapy is significantly less than it is for surgery

The data showed that in the three years analyzed, 472,000 patients were diagnosed with LBP. Of these beneficiaries, 60,000 (12.7%) received physical therapy as their first line of treatment, while 53,000 (11.3%) were treated with injections, 8,000 (1.6%) had surgery and 351,000 (74.4%) did not receive any of these treatments in the one year following their diagnosis. The analysis revealed that for the beneficiaries that received physical therapy first, the total Medicare spending was about 19% less than it was for injections and about 75% less than spending for patients who had surgery. In addition, within one year after the LBP diagnosis, the difference in average spending was 18% between the therapy first group and injection first group and about 54% between the therapy first group and surgery first group. Finally, beneficiaries who received physical therapy within the first 15 days after being diagnosed with LBP had costs that were about 27% lower down the line than those who received therapy 45-90 days after their diagnosis.

These results show that physical therapy has the lowest Medicare costs of the three treatments analyzed for LBP and that these costs are even lower if patients begin treatment within the first 15 days of being diagnosed. In some cases, this can wind up saving patients money in the long run if they are treated with physical therapy instead of a much more expensive option like surgery. Patients should, therefore, keep this information in mind when deciding if they should seek out treatment for LBP and when considering surgery if a doctor recommends it.

Therapy reduces pain and stiffness in patients with knee arthritis

This particular treatment is commonly used to address a prevalent condition

Joints are the area where two bones come together, and the end of each joint is surrounded by a protective layer called articular cartilage, which cushions your bones and protects them from rubbing against one another. When this cartilage diminishes, the condition that results is called osteoarthritis. Osteoarthritis is the most common form of arthritis and the leading cause of disability and pain in middle-aged and elderly people throughout the world. It can occur in any joint in the body, but it is most common in the knees and hips. Of the many treatments available for knee osteoarthritis, manual therapy is one of the more popular used today. Manual therapy means that the therapist uses only their hands to apply various movements and techniques to the joint in order to reduce pain and other symptoms. Although manual therapy is a frequently used treatment for knee osteoarthritis, it’s not completely clear just how effective it is for reducing patients’ symptoms. For this reason, a powerful pair of studies called a systematic review and meta-analysis was conducted on all the available research on this topic.

14 studies are accepted for the review

To conduct the study, researchers performed a search of seven medical databases using terms related to manual therapy and knee osteoarthritis. They only accepted randomized-controlled trials (RCTs), which are high-quality studies considered to be the gold standard for evaluating whether a treatment is effective or not. This search led to 99 studies being screened to determine if they were eligible, and of these, 14 RCTs fit the necessary criteria and were accepted for the systematic review and meta-analysis. The findings of each of these RCTs were compared to one another and researchers also assessed their quality.

Manual therapy found to significantly reduce pain, alleviate stiffness and improve function

Results showed that manual therapy was found to significantly reduce pain, alleviate stiffness and improve the physical function in patients with knee osteoarthritis. These positive effects of manual therapy occurred with less than four weeks of treatment, but a treatment course lasting longer than four weeks led to even greater benefits. In addition, only one patient experienced increased discomfort from manual therapy, while no other negative effects were found in any of the other studies. Unfortunately, the quality of the studies included in this systematic review and meta-analysis was not very high due to certain flaws in their design. Nonetheless, these findings indicate that manual therapy is a beneficial treatment for knee osteoarthritis and should be used in treatment programs for patients with this condition. Due to the poor quality of the studies included, additional high-quality RCTs are needed with better design and a longer follow-up to further confirm these findings.

Exercise therapy leads to better flexibility for jaw condition

Results from previous studies are inconsistent on effectiveness of treatment

Temporamindibular joint disorder (TMJ) is an umbrella term used to describe several conditions that involve a dysfunction of the jaw. The most common symptoms of TMJs are pain and decreased mobility of the jaw, both of which have a negative impact on patients’ quality of life. There are a number of conservative (non-surgical) treatments available for TMJs, including physical therapy interventions such as exercise-based therapy, massage, stretching and a combination of these techniques. Exercise therapy programs are commonly used to treat TMJs and may include aerobic, stretching, balance and strengthening exercises, but the available studies on this intervention have produced results that are inconsistent. For this reason a powerful pair of studies called a systematic review and meta-analysis was conducted on the effectiveness of exercise therapy for patients with a TMJ. A systematic review collects all the available evidence on a topic, and in the meta-analysis, researchers pool the data from these studies to tease out common trends.

Two medical databases are searched for relevant studies

Researchers performed a search of two major medical databases for high-quality studies that evaluated exercise therapies for TMJ. They only accepted randomized-controlled trials (RCTs), which are considered the gold standard of individual studies used to determine if a treatment is effective. The search identified 37 studies to be screened, and of these, six RCTs fit the necessary criteria and were used for the systematic review and meta-analysis. All included studies were then analyzed and their findings were compared to one another to determine if exercise therapy was in fact effective for TMJs, and their quality was also ranked to gauge their reliability.

Exercise therapy leads to several benefits for patients

After completing the systematic review and meta-analysis, researchers found that exercise therapy reduced pain and improved the range of motion (flexibility) of patients with TMJs. The improvements in flexibility came primarily from programs that emphasized mobility exercises and a mixed treatment programs, and it appeared that twice weekly was the most effective treatment method for reducing pain. However, it’s not clear what the most appropriate type, intensity and duration of exercise therapy should be for the best results. Therefore, more research is needed to investigate these factors in more detail. Nonetheless, these studies clearly show that exercise therapy is an effective treatment for reducing pain and improving flexibility in patients with a TMJ. Individuals with this condition should therefore be encouraged to seek out the treatment of a physical therapist for an appropriate treatment program that will help them improve.
