Clinical Assessment and Pedobarographic Analysis after Radial Shock Wave Therapy of Ankle Plantar Flexor Spasticity in Stroke

Abstract

Objective: Radial shock wave therapy (RSWT) has increasingly been utilized in the treatment of spasticity recently. The purpose of the current study is to assess the effectiveness of RSWT in the treatment of ankle plantar flexor muscles spasticity of stroke patients by pedobarography and clinical evaluation. Materials and Methods: A total of 23 stroke patients were enrolled into the study. Patients received an initial sham treatment of RSWT, followed by three separate interventional sessions received one week apart. Treatment success was assessed using the Modified Ashworth Scale (MAS), ankle passive range of motion (pROM) measurement and pedobarography. Results and Discussion: No significant change was observed in clinical and pedobarographic values following sham RSWT. In the intervention group, however, MAS decreased from3.34±0.7 to 2.39±0.89 after a single RSWT session and to 2.04±0.92 first week and to 2.52±0.89 fourth week after three RSWT sessions. As a result of the study, heel peak pressure and total plantar contact area were improved. In particular, three RSWT sessions were more effective than single RSWT session. Conclusions: We observed a significant improvement in plantar flexor spasticity in stroke patients after both a single and three RSWT sessions and this improvement persisted during the four-week study period.
