What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test a non-invasive treatment called Strain-Counterstrain, targeting the piriformis muscle to relieve pain from piriformis syndrome. Participants will receive either the actual treatment on the piriformis muscle or a sham treatment on the hamstring for comparison. Ideal candidates for this trial are individuals with a tender or trigger point in their piriformis muscle, identified during a physical exam. As an unphased trial, this study offers participants the chance to contribute to innovative research that may lead to new pain relief methods.

Do I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications.

What prior data suggests that the Strain-Counterstrain treatment is safe for the piriformis muscle?

Research shows that strain-counterstrain treatment is generally easy for patients to handle. This method, also called positional release, involves gently moving the body to ease muscle pain. Studies have not found any major side effects, making it a safe choice for most people. It offers a hands-on approach to relieve muscle and bone discomfort without surgery or injections. Since strain-counterstrain is already used for other muscle problems, current practices support its safety. Participants considering this trial can feel confident about the treatment's safety based on its current use and research findings. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Strain-Counterstrain treatment for piriformis syndrome because it offers a non-invasive and targeted approach to relieving muscle pain. Unlike standard treatments like physical therapy, anti-inflammatory medications, or corticosteroid injections, this technique involves gently positioning the body to alleviate the stress on the piriformis muscle, potentially reducing pain without medication. This method might provide a safer alternative for those unable to take medications and could offer quicker relief compared to traditional therapies. Overall, it represents a promising new way to manage muscle-related pain with minimal side effects.

What evidence suggests that Strain-Counterstrain treatment might be an effective treatment for piriformis syndrome?

Research has shown that strain-counterstrain treatment can effectively reduce pain from the piriformis muscle. This trial will compare two applications of strain-counterstrain: one targeting the piriformis muscle and another targeting the hamstring muscle as a sham comparator. This method has shown promise in easing discomfort and increasing movement in patients with similar issues. In cases of sudden low back pain, strain-counterstrain has proven effective on its own, indicating it might help with muscle-related pain. For those with piriformis syndrome, this treatment could reduce tender spots by up to 70%, helping to relieve pain and improve movement. These findings suggest that strain-counterstrain could be a useful option for managing piriformis syndrome. ^{1 2 6 7 8}

Published Research Related to This Trial

A case study of a man in his late 40s with piriformis syndrome showed that a botulinum toxin (BoNT) injection significantly relieved his pain, lasting for 2 years after the second injection.

The study suggests that increasing the dilution volume of the BoNT injection may enhance its therapeutic effectiveness for treating piriformis syndrome.

A single strain-counterstrain intervention did not significantly improve cervical range of motion compared to a sham treatment in 61 patients with neck pain, with only a 1.5% difference in mobility restriction after treatment.

Both groups showed improvement after receiving full individualized osteopathic treatment, suggesting that the overall osteopathic approach may be more effective than strain-counterstrain alone.

In a study involving 60 patients with mechanical neck pain, the addition of the Strain-counterstrain technique (SCS) to standard therapy significantly improved pain levels, pressure pain thresholds, and disability scores compared to standard therapy alone.

The results suggest that SCS is an effective treatment method for enhancing recovery in patients with mechanical neck pain, supporting its use in clinical practice to improve patient outcomes.

The strain and counterstrain (SCS) technique showed promising results in reducing pain and improving function in 19 out of 20 patients with chronic myofascial pain who had not responded to standard treatments, with improvements ranging from 50% to 100%.

After SCS therapy, 11 of the 20 patients maintained partial improvement for 6 months, and 4 patients reported being pain-free, suggesting that SCS could be a valuable adjunctive therapy for chronic pain disorders.

Piriformis syndrome, which causes sciatica-like symptoms due to compression of the sciatic nerve by the piriformis muscle, is more commonly diagnosed in females and can lead to tingling, numbness, and pain.

Various physiotherapy techniques, including nerve mobilization and stretching, have been shown to effectively manage piriformis syndrome, with nerve gliding techniques causing less strain on the nerve compared to tensioning techniques.

Ultrasound-guided dry needling is proposed as a novel treatment approach for piriformis syndrome, which is caused by the compression of the sciatic nerve under the piriformis muscle.

This method offers a different perspective compared to traditional treatments like physical therapy, stretching, and injections, potentially providing effective relief for patients suffering from this painful condition.

The study identified optimal injection sites for botulinum neurotoxin in the piriformis muscle, based on nerve distribution patterns observed in 15 specimens, which can enhance treatment efficacy.

Clinicians can use these guidelines to improve the effectiveness of various injection treatments (like steroids and anesthetics) while minimizing the risk of adverse outcomes.
