An interventional study of Reciprocal Inhibition MET and Post-facilitation MET in Piriformis Syndrome, sponsored by Foundation University Islamabad. Status unknown at 1 site in Pakistan. Open to participants aged 20 Years to 50 Years. Per ClinicalTrials.gov, last updated 2024-08-02.

This study is a randomized controlled trial and the purpose of this study is to compare the effects of reciprocal inhibition versus post facilitation muscle energy technique along with conventional physical therapy in patients with piriformis syndrome in terms of pain, range of motion at hip joint and functional disability.
This study aims to compare the effects of reciprocal inhibition with post facilitation muscle energy technique along with conventional physical therapy in terms of pain, functional disability and range of motion at hip joint in patients with piriformis syndrome to find the best suitable and effective treatment for it based on the outcomes.
Males and females between the age of 20-50 years, having buttock pain of ≥ 3 on NPRS since 3 months or more and a score of ≥ 8 on a 12-point clinical scoring system as well as any two of the positive screening tests will be recruited in this study as patients of piriformis syndrome.
These subjects will be selected via non-probability purposive sampling technique, followed by randomization into two groups using blocked randomization method.
A total of 6 treatment sessions will be given to each participant over the duration of 2 weeks with a total of 3 follow-ups after every 2 sessions.
TENS and hot pack followed by reciprocal inhibition technique will be given to the experimental group A, while the active comparator group B will be given TENS and hot pack followed by post-facilitation muscle energy technique.
Both the groups will be guided about the strengthening exercises given as a home plan.
56 studies on the registry are indexed under Piriformis Muscle Syndrome; 23 are open to participants now.
This study's planned enrollment of 44 is close to the median of 42 across 50 interventional studies indexed under Piriformis Muscle Syndrome.

Exclusion Criteria:
RI-MET group A will receive 3-5 repetitions of reciprocal inhibition to the shortened piriformis muscle in supine and prone positions i.e. 30-50% isometric contraction of the muscle opposite to the muscle to be stretched for 7-10 seconds, followed by inhalation, exhalation and rest period of 5 seconds and then a stretch (through the new barrier with patients' assistance) of 10-60 seconds hold.both groups will receive conventional physical therapy which they will be taught as a home plan. Following exercises are guided to the patient as home plan. * Resisted abduction with Thera/resistance band * Resisted bridging with Thera/resistance band * Resisted clam exercise with Thera/resistance band
Other: Reciprocal Inhibition MET · Other: Conventional physical therapy
PFS-MET group will receive 3-5 repetitions of post-facilitation stretch to the shortened piriformis muscle in supine and prone positions i.e. 20% maximal isometric contraction of the muscle to be stretched for 6-10 seconds, followed by a rapid stretch (through the new barrier) of 15 seconds hold. After stretch, the muscle is allowed to relax in the midrange for up to 30 seconds.Both groups will receive conventional physical therapy which they will be taught as a home plan. Following exercises are guided to the patient as home plan. * Resisted abduction with Thera/resistance band * Resisted bridging with Thera/resistance band * Resisted clam exercise with Thera/resistance band
Other: Post-facilitation MET · Other: Conventional physical therapy
Reciprocal Inhibition MET will be applied to the shortened piriformis muscle in supine and prone positions with participants using 30-50% of their maximum voluntary isometric contraction. It will include 30-50% isometric contraction of the muscle opposite to the muscle to be stretched for 7-10 seconds, followed by inhalation, exhalation and rest period of 5 seconds and then a stretch (through the new barrier with patients' assistance) of 10-60 seconds hold. RI-MET group will receive 3-5 repetitions.
Post-facilitation stretch technique for shortened piriformis muscle in supine and prone positions will be applied with participants using 20% of their maximum voluntary isometric contraction. It will include 20% maximal isometric contraction of the muscle to be stretched for 6-10 seconds, followed by a rapid stretch (through the new barrier) of 15 seconds hold. After stretch, the muscle is allowed to relax in the midrange for up to 30 seconds. PFS-MET group will receive 3-5 repetitions.
TENS and hot pack application to provide heating effect over the painful area (10 minutes) Both groups will receive conventional physical therapy which they will be taught as a home plan. Following exercises are guided to the patient as home plan. * Resisted abduction with Thera/resistance band * Resisted bridging with Thera/resistance band * Resisted clam exercise with Thera/resistance band
Pain Intensity
The pre and post pain intensity will be measured using Numeric Pain Rating Scale (NPRS) comprising of 11 points from 0 - 10 where 0 indicates "no pain" while 10 is "maximally felt pain".
Time frame: 2 weeks
Hip range of motion
Goniometer will be used to measure the pre and post treatment ranges of internal rotation, external rotation, abduction and adduction at hip joint in supine and sitting positions.
Time frame: 2 weeks
Functional Disability
Lower Extremity Functional Scale comprising of 20 questions regarding lower extremity function will be used. The maximum possible score is 80 points, indicating very high function. The minimum possible score is 0 points, indicating very low function.
Time frame: 2 weeks
