Purpose To examine the effects of radial extracorporeal shockwave therapy (rESWT) on plantarflexor spasticity after stroke. Method Twelve patients with stroke were randomly included for this prospective, single-blind clinical trial. Patients received one rESWT session (0.340 mJ/mm(2), 2000 shots) on plantarflexor muscle. The Modified Modified Ashworth Scale (MMAS), H-reflex tests, ankle range of motion (ROM), passive plantarflexor torque (PPFT) and timed up and go test (TUG) were measured at baseline (T-0), immediately after treatment (T-1) and one hour after the end of the treatment (T-2). Results Patients had improved the MMAS scores for both the gastrocnemius and the soleus muscles, active and passive ROM, PPFT and TUG over time after rESWT. For the PPFT, it was greater at high velocity than at low velocity, and there was a significant three-way interaction between time, knee position (extended/flexed) and velocity (low/high). The H-reflex latency had decreased at T-1, but there was no significant effect on H-max/M-max ratio. Conclusions The rESWT improved plantarflexor spasticity, and the effects sustained for one hour, whereas it was not effective in improving spinal excitability.
