Effects of joint mobilization and stretching on the range of motion for ankle joint and spatiotemporal gait variables in stroke patients

Abstract

Background and purposeStroke patients have limited ranges of motion and gait disturbances due to neurological deficits and connective tissue changes. We assessed the effects of joint mobilization and active stretching on ankle joint range of motion and gait in stroke patients. MethodsIn total, 45 stroke patients were evenly divided into three groups: joint mobilization, active stretching, and combination (joint mobilization and active stretching) groups. Patients in each group received the corresponding interventions in a non-simultaneous manner for 6 weeks in total (3 days per week, 15 min per day). The range of motion of the ankle joint was measured using a goniometer, and spatiotemporal gait variables were measured using G-walk. All measurements were taken immediately before and after the 6-week intervention. ResultsThe joint mobilization group exhibited significantly increased range of motion for ankle joint after the intervention (p < 0.05), while the spatiotemporal gait variables were unchanged. In the active stretching group, both the range of motion of the ankle joint in the supine position and the spatiotemporal gait variables (cadence, speed, stride length) were significantly increased (p < 0.05). In the combination group, both the range of motion of the ankle joint and spatiotemporal gait variables (cadence, speed, stride length) were significantly increased (p < 0.05). ConclusionCombination therapy of joint mobilization and active stretching improves the range of motion of the ankle joint and spatiotemporal gait variables in stroke patients, suggesting that ankle rehabilitation of stroke patients should include limited joint structure and muscles shortness.
