Background: Spasticity is a common motor impairment in patients with stroke that not only has a negative impact on the patient’s quality of life but also has high economic burdens for society. Recently the application of shock wave therapy has attracted considerable attention as a safe and effective method in treatment of spasticity. The objective of the present study was to investigate the effect of application shock wave on spasticity of quadriceps femoris and triceps surae muscles in patients with stroke.
Methods: This was a quasi-experimental study on 15 stroke patients which were selected according to inclusion criteria between September 2016 and May 2017. This study was approved by the Ethics Committee of Shahid Beheshti University of Medical Sciences, Iran. The intervention included one session placebo shock wave and three sessions of true shock wave. Level of the spasticity was measured at quadriceps and gastrocnemius muscles by Ashworth scale (AS) and passive range of motion (PROM) of the knee and ankle joints was recorded by a manual goniometer (Enraf-Nonius Corp., Delft, Netherlands). Participants were assessed at baseline, after the placebo shock wave, after the final session of active shock wave and 4 weeks after the last treatment.
Results: Placebo shock wave had not significant effect on grade of AS of spastic muscles as well as PROM of knee and ankle joints. True shock wave induced a statistically significant reduction in AS of triceps surae and quadriceps femoris muscles and improvement of PROM of knee and ankle joints. The reduction in AS of triceps surae and improvement of ROM ankle joint continued 4 weeks after the last treatment. However, after 4 weeks, there was a significant reduction in the PROM of knee joint compared to the last session.
Conclusion: Three sessions shock wave therapy can reduce the tone of triceps surae and quadriceps muscles and improved the passive range of motion in the knee and ankle joints for up to 4 weeks, but these effects were not stable on the PROM knee joint.
