Abstract
Background: Poststroke spasticity (PSS) is a common complication of stroke. Current PSS treatments have been linked to high costs, lack of long-term effectiveness, and undesirable side effects. Vibrational and heated stone-needle therapy (VHS) has not been utilized to treat PSS, and its safety and effectiveness have yet to be proven by high-quality clinical research. Objective: The aim of this study was to determine the effectiveness of VHS combined with meridian dredging exercise (MDE) in patients with PSS. Methods: One hundred participants with stroke were included and randomly assigned to a treatment group (VHS plus MDEs) and a control group (MDEs alone). Patients in both groups were treated for 4 weeks. The primary outcome measures were the Modified Ashworth Scale (MAS) and Fugl-Meyer Assessment (FMA), while the secondary outcome measures were the Activity of Daily Living (ADL) Scale and Stroke-Specific Quality of Life Scale (SS-QOL). The evaluations were at baseline (T0) at 4 weeks of treatment (T1) and at 12 weeks of follow-up without treatment (T2). Results: At T1 and T2, there were significant differences in MAS between the two groups (p = 0.001). From the perspective of distribution, the VHS plus MDE group had significant changes, and the group-time interactions of upper and lower extremities in FMA, ADL, and SS-QOL were statistically significant (p < 0.001), indicating that patients’ symptoms improved after treatment. But the overall effect size is small, especially the effect size of improvement in SS-QOL at T1. Conclusion: VHS in combination with MDE can consistently alleviate PSS, enhance limb function, and improve the quality of life of patients with PSS. But we need to optimize the device further and observe the improvement of patients for a more extended period.
