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.
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.

Numeric Pain Rating Scale
Numeric Pain Rating Scale (NPRS) was used to assess the patient's pain intensity. This scale ranges from 0 to 10, where 0 indicates "no pain" and 10 indicates "worst pain.
Time frame: From enrollment to 6 weeks of intervention with follow-up at 14 weeks.
Range of Motion (Hip Abduction)
The universal goniometer was used to assess hip abduction range of motion.
Time frame: From enrollment to 6 weeks of intervention with follow-up at 14 weeks.
Range of Motion (Hip Internal Rotation)
The universal goniometer was used to assess hip internal rotation range of motion.
Time frame: From enrollment to 6 weeks of intervention with follow-up at 14 weeks.
Lower Extremity Functional Scale
Lower Extremity Functional Scale was used to assess the patient's functional status. Maximum score of this scale is 80. The greater the score, the lower the disability.
Time frame: From enrollment to 6 weeks of intervention with follow-up at 14 weeks.

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.
