Abstract
En 中文
Lumbar spondylosis is a common degenerative condition in older adults, leading to chronic low back pain, spinal stiffness, and functional limitation. This study compared radial shockwave therapy (RSWT) and short-wave diathermy (SWD) for pain and lumbar function in older adults with lumbar spondylosis. Thirty participants aged ≥60 years were randomized to RSWT (n = 15) or SWD (n = 15). Both groups received eight sessions over four weeks, twice weekly, with identical standardized adjunctive co-interventions consisting of superficial heat and home-based lumbar and hamstring stretching. Pain intensity, pressure pain threshold (PPT), lumbar range of motion (ROM), and Oswestry Disability Index (ODI) were assessed at baseline and weekly after treatment. Data were analyzed using mixed ANCOVA with baseline adjustment and Bonferroni post hoc tests. Both interventions reduced pain after four weeks (p < 0.05). RSWT showed a significant within-group increase in PPT and a transient between-group advantage at week 2 (p = 0.049). RSWT produced greater improvement in lumbar flexion ROM, with significant time, group, and Group × Time effects (p < 0.05). ODI improved in both groups, with a significant Group × Time interaction (p = 0.014). RSWT may provide additional short-term benefits over SWD for selected outcomes, particularly pressure pain sensitivity, lumbar flexion mobility, and disability trajectory. However, both modalities reduced pain, and between-group superiority should be interpreted cautiously because not all outcomes showed significant Group × Time effects.
