Summary

The study was conducted to determine the effects of McGill strengthening exercises program with and without integrated neuromuscular inhibition technique on pain, range of motion and function in patients with piriformis syndrome.

Conditions

• Piriformis Syndrome

Interventions

Type	Name	Description
OTHER	McGill strengthening exercises program	These exercises were divided into 3 phases, each lasting 2 weeks. Patients performed 4 repetitions of each exercise during 1st and 2nd week at each hospital visit. Then, increased by 4 repetitions every 2 weeks for up to 6 weeks. These exercises were performed with a maximum of 12 repetitions with a 1-minute of rest interval between each exercise. These exercises were performed by patients at each clinical visit, 3 days per week for total of 6 weeks.
OTHER	Integrated neuromuscular inhibition technique	This technique was applied at piriformis muscle. The procedure was repeated 3 times for up to 10 minutes at each clinical visit. This intervention was performed 3 days per week for total of 6 weeks.
OTHER	Standardized physiotherapy treatment	These exercises were performed by patients at the end of each hospital visit (3 days per week for total of 6 weeks) and also at home twice a week during the 2 months follow-up period after treatment ends. 1. Continuous-mode ultrasound therapy was applied at a frequency of 1 MHz and an intensity of 1.0 W/cm² for 3 minutes to the tender or trigger points on the posterior aspect of the pelvis. 2. A hydrocollator pack (40°C) was applied for 10 minutes at lumbopelvic region. 3. Piriformis, hamstring/calf stretching was performed progressively in phases. * Phase 1 consists of weeks 1 and 2 with 1 set of 3 repetitions with 30 seconds hold per day. * Phase 2 consists of weeks 3 and 4 with 2 sets of 3 repetitions with 30 seconds hold per day. * Phase 3 consists of weeks 5 and 6 with 2 sets of 3 repetitions with 30 seconds hold twice per day. * Follow-up period consists of 2 sets of 3 repetitions with 30 seconds hold twice per day.
