An interventional study of Myofascial Release and Post Isometric Relaxation in Piriformis Syndrome, Musculoskeletal Abnormalities and Sciatica, sponsored by University of Faisalabad. Not yet recruiting at 1 site in Pakistan. Open to participants aged 20 Years to 50 Years. Per ClinicalTrials.gov, last updated 2026-06-30.

Piriformis Syndrome is a neuromuscular condition with symptoms of pain, numbness and tingling tracing the route of the sciatic nerve, due to the nerve impingement by the piriformis muscle. Two common manual therapy techniques used to treat musculoskeletal conditions are myofascial release and post-isometric relaxation. The intent of the research is to evaluate the effects of myofascial release (MFR) as compared to post-isometric relaxation (PIR) in improving pain and lower extremity function in piriformis syndrome (LEFS). The study population involved 32 individuals aged between 20 to 50 years who will be randomly assigned to two groups; a group that received MFR and a group that received PIR. Both groups received the baseline treatment for four weeks. The Visual Analog Scale (VAS) will be employed to gauge the amount of pain, while the LEFS was used to measure functional mobility
This is Multiple-center, randomized controlled trail. Participants age 20-50 years with diagnosed piriformis syndrome will be referred from neuro physician and orthopedic department of Madina Teaching hospital (MTH) to Physiotherapy ward, Jafar Physiotherapy Clinic and Madina Specilaists Clinic. After informed consent Participants will be randomly assign to one of two parallel groups using a random number generator. Group A (Experimental): Receive MFR 3 sessions per week for total duration 4 weeks. Group B (Active Comparator) receive the PIR 3 sessions per week for total duration 4 weeks. Outcome measures (pain via VAS, functional status via LEFS) are taken at baseline and end of treatment. Data will be analyzed using Spss version 20.

Exclusion Criteria:
Lower extremity injuries including ligament, tendon injuries, muscle strains as well as nerve injuries
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Myofascial release was then performed with the patient positioned in prone lying. The piriformis muscle was identified. Sustained pressure was applied directly to the trigger point/piriformis muscle for 10-100 seconds while the patient actively moved the affected limb repeatedly from internal to external rotation. Kneading strokes parallel to the muscle fibers were then performed for 5 minutes to promote elongation. This sequence was repeated three times.
Other: Myofascial Release
The patient is in supine and the hip in neutral rotation. The affected hip was passively moved into horizontal adduction until a mild stretch was felt, while the lumbar spine was stabilized. The patient performed a gentle isometric contraction into hip abduction for 7-10 seconds, followed by 2-3 seconds of relaxation. The leg was then moved into further adduction to a new barrier. This contraction-relaxation-stretch cycle was performed for 3 sets of 5 repetitions.

Visual analogue scale
Comparison on effect of pain. The Visual Analog Scale is a self-reported measure of pain intensity. Participants rate their pain on a 10-cm scale ranging from 0 to 10, where 0 indicates "no pain" and 10 indicates "worst imaginable pain."
Time frame: Baseline and 4 week post intervention
Lower Extremity Functional Scale
Comparison on effect of functional outcomes. The Lower Extremity Functional Scale (LEFS) is a self-reported questionnaire used to assess functional status and difficulty performing everyday activities in individuals with lower extremity musculoskeletal conditions. The scale consists of 20 items, each scored from 0 to 4, yielding a total score ranging from 0 to 80.
Time frame: Baseline and 4 week of post intervention
