The Effects of Vibration on Lower Limb Muscle Strength, Functional Status, and Psychological Health in Stroke Patients

Summary

The goal of this clinical trial is to the effect of vibration training on lower limb muscle strength, functional status and psychological health of stroke patients. The main questions it aims to answer are:

* Lower limb muscle strength was measured using the Medical Research Council Manual Strength Test.
* Functional status was measured using Postural Assessment Scale for Stroke, and the Barthel scale.
* Psychological health was measured using the Hospital Anxiety and Depression Scale.

Participants will be randomly assigned to four groups:

1. Control group: Receives only rehabilitation training and standard treatment.
2. Comparison group: Receives rehabilitation training, standard treatment, and a 30-minute stationary cycling intervention during hospitalization for 5 days.
3. Experimental group 1: Receives rehabilitation training, standard treatment, and a 30-minute wearable lower-limb high-frequency, low-amplitude vibration therapy during hospitalization for 5 days, followed by 30 minutes of stationary cycling.
4. Experimental group 2: Receives rehabilitation training, standard treatment, and a 30-minute vertical lower-limb low-frequency, high-amplitude vibration therapy during hospitalization for 5 days, followed by 30 minutes of stationary cycling.

All participants will undergo an initial measurement within 4 hours of admission, followed by the second and third measurements after the 5-day intervention and on the day of discharge, respectively.

Conditions

Interventions

BEHAVIORAL

wearable vibration

In addition to standard rehabilitation, participants receive 5 days of stationary cycling training combined with localized vibration therapy administered using a wearable vibration device. Vibration parameters are set at a frequency of 30 Hz and amplitude of 1 mm, targeting the lower-leg muscle groups. Each session lasts 30 minutes and begins within 1-2 days of admission.

BEHAVIORAL

vertical vibration

In addition to standard rehabilitation, participants receive 5 days of stationary cycling training combined with vertical vibration therapy for the lower limbs. Vibration parameters are set at a frequency of 20 Hz and amplitude of 3 mm. Each session also lasts 30 minutes and begins within 1-2 days of admission.

BEHAVIORAL

early rehabilitation

In addition to standard stroke treatment, participants receive 5 days of stationary cycling training in the acute stroke unit beginning 1-2 days after admission (at least 24 hours after the stroke onset). The cycling session lasts approximately 30 minutes, including a 5-minute warm-up, 20-minute training session, and 5-minute cool-down.

BEHAVIORAL

regular treatment

Receives only standard stroke treatment and rehabilitation therapy.
