Quantitative Data to Evaluate Clinical Pilates Efficacy in Chronic Low Back Pain Using Inertial Measurement Units

Chronic non-specific low back pain (CNLBP) affects a significant percentage of the global population, with therapeutic exercise being a key management strategy. This study evaluated the effectiveness of the clinical Pilates method in 22 patients with CNLBP. Lumbar spine range of motion (ROM) and completion times for three functional tests (prone plank, side bridge, and supine bridge) were measured before and after a six-week rehabilitation program. Motion data were collected using two inertial measurement units. Results showed statistically significant improvements in kinematic patterns, execution times, and ROM. These findings support the effectiveness of clinical Pilates in improving lumbar spine functionality and patient outcomes.
