Brief summary
This pilot study evaluates whether passive static stretching can improve hip movement in three groups: people who have had hip replacement surgery, individuals with long-term hip pain, and healthy volunteers. Participants will follow a 4-week stretching program, doing exercises three times per week under the supervision of a trained clinician. Hip range of motion will be measured before and after the program using accurate electronic sensors. The goal is to determine if passive static stretching is a safe and effective way to increase hip flexibility and support daily activities. The study involves no new medications or invasive procedures and is considered low risk.
Detailed description
This pilot study investigates the effects of passive static stretching on hip range of motion (ROM) in three populations: patients who have undergone total hip arthroplasty (THA), individuals with chronic non-surgical hip pain, and healthy volunteers. A total of 12 participants will be enrolled, divided equally into three groups. Participants will follow a four-week stretching program, performing assisted hip flexion and abduction exercises three times per week, with each stretch held for 30 seconds. All sessions are supervised by a trained kinesiologist to ensure proper alignment, submaximal intensity, and participant safety. Hip ROM will be measured pre- and post-intervention using high-precision triaxial electronic sensors (accelerometers and gyroscopes) under standardized conditions. The study will track changes in hip flexion and abduction, monitor for adverse events, and assess compliance. The purpose is to explore whether passive static stretching is a safe, feasible, and effective method to enhance hip mobility across different populations, providing preliminary data for future larger studies.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Hip Range of Motion (Flexion and Abduction) | 4 weeks (pre- and post-intervention) | Hip ROM was measured using high-precision triaxial electronic sensors equipped with accelerometers and gyroscopes (Sensorize). Participants were assessed in standardized positions over the hip joint, with data sampled at 200 Hz to determine maximal flexion and abduction angles. Measurements were taken pre- and post-intervention across all groups. |
