BACKGROUND: Piriformis syndrome is a neuromuscular condition that is thought to be triggered by compression of the sciatic nerve just at the level of the piriformis muscle. Pain and tenderness in the buttock area and the back of the upper leg, either with or without radiating the leg, are the risk factors for developing Piriformis syndrome.

OBJECTIVE: To determine the prevalence of piriformis syndrome and its association with Body Mass Index among bankers in Lahore.

METHODOLOGY: A cross-sectional study design was used. Data was collected from all banks in Lahore. Non- Probability convenient sampling was used. The sample size was 377. A demographic questionnaire was used to collect data. Piriformis syndrome was assessed by a piriformis stretch test in sitting. The data was analyzed using SPSS version 25.

RESULTS: The prevalence of Piriformis syndrome in bankers was 30.8%. Out of 377 (M: 287, F: 90), 116 (30.8%) bankers had piriformis syndrome, 45(11.9%) had the right side involved, 58 (15.4%) had the left side involved and 13 (3.4%) had bilateral involvement.
