Stroke Clinical Trial - Comparing ESWT Doses for Post-Stroke Ankle

Status Recruiting

Clinical Trial Summary

Post-stroke spasticity is a common complication affecting the neurological recovery, self-care daily activities and patients' quality of life. Extracorporeal shock waves (ESWT) have been proven therapeutic effects on decreasing spasticity and regaining function. Stroke patients often suffer ankle plantar flexor spasticity with poor ankle movement control, leading to abnormal gait patterns and risk of falling; local pain appears as well in the ankle. Research showed application of ESWT to lower extremity spasticity reduced ankle plantar flexor spasticity, ankle pain and increased the range of ankle motion. However, the current study did not investigate the effect of ESWT on different muscles in patients with post-stroke ankle spasticity. Therefore, this study will compare the effect of focused ESWT on combination of the gastrocnemius and soleus muscles to gastrocnemius muscle alone in the post-stroke ankle plantar flexor spasticity.

Clinical Trial Description

This study design was a single-blind randomized controlled trial and planned to recruit 40 chronic stroke patients with ankle plantar flexor spasticity. The patients were randomly assigned to two groups. The experimental group received focused ESWT to gastrocnemius and soleus muscles (2000 shots for each muscle, a total of 4000 shots per session), while the control group received focused ESWT to gastrocnemius muscle (2000 shots per session). Patients in both groups underwent a total of 4 sessions ESWT, twice a week for two consecutive weeks. The depths of ESWT to gastrocnemius and soleus muscle were determined by ultrasound. All patients received traditional rehabilitation. The primary outcome was modified Ashworth scale; the secondary outcomes were modified Tardieu scale, passive range of ankle motions and timed up and go test, and ultrasound evaluations (pennation angle and strain elastography of muscles). The outcomes were assessed before ESWT and after ESWT at 1, 4, 12, and 24 week. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
