Effectiveness of Dry Needling Therapy on Pain, Hip Muscle Strength, and Physical Function in Patients With Hip Osteoarthritis: A Randomized Controlled Trial.

摘要: Abstract Objective To investigate the short-term effects of dry needling (DN) on physical function, pain, and hip muscle strength in patients with osteoarthritis (OA). Design A double-blind, placebo-control, randomized controlled trial. Setting Private practice physiotherapy clinic. Participants Patients unilateral OA (N=45) were randomly allocated to a DN group, sham or control group. Interventions groups received 3 treatment sessions. Three active myofascial trigger points (MTrPs) treated each session needle procedure. The was applied MTrPs iliopsoas, rectus femoris, tensor fasciae latae, gluteus minimus muscles. Main Outcome Measures Physical function assessed Western Ontario McMaster Universities (WOMAC) subscale, timed Up Go test, 40-meter self-paced walk test. Intensity pain related evaluated using visual analog scale WOMAC subscale. maximal isometric force muscles recorded handheld dynamometer. Results Significant group by time interactions shown for variables. Post hoc tests revealed significant reduction improvements compared groups. showed within- between-groups large effect sizes (d>0.8). Conclusions therapy reduced improved OA. should be considered management
