简要总结
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:
- Control group: Receives only rehabilitation training and standard treatment.
- Comparison group: Receives rehabilitation training, standard treatment, and a 30-minute stationary cycling intervention during hospitalization for 5 days.
- 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.
- 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.
详细描述
Standard care for all study participants includes conventional rehabilitation therapy for stroke. This therapy involves physical therapy (e.g., posture training, endurance training, muscle strength training) and occupational therapy provided at the rehabilitation center. Such rehabilitation typically begins 3-6 days after admission and is administered by a physical or occupational therapist.
- Control group: Receives only standard stroke treatment and rehabilitation therapy.
- Comparison group: Additionally, using stationary lower leg pedal bike (WP-698) with moderate intensity.
- Experimental group 1: In addition to standard rehabilitation, participants receive 5 days of stationary cycling training combined with localized vibration therapy with a wearable vibration device (Myovolt).
- Experimental group 2: In addition to standard rehabilitation, participants receive 5 days of stationary cycling training combined with vertical vibration therapy for the lower limbs with COZY FIT vertical vibration machine (HY-806-BK)

研究组 & 干预措施
Control group
Receives only standard stroke treatment and rehabilitation therapy.
干预措施: regular treatment (Behavioral)
Stationary cycling training
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.
干预措施: early rehabilitation (Behavioral)
Stationary cycling training
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.
干预措施: regular treatment (Behavioral)
Stationary cycling training combined with localized vibration therapy
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.

结局指标
主要结局
Psychological health
时间窗: 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, an average of 11 days, respectively.
Using the Hospital Anxiety and Depression Scale.
Lower-limb muscle strength
时间窗: 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, an average of 11 days , respectively.
Using the Medical Research Council Manual Strength Test. Muscle strength was assessed by evaluating the ability of the limbs to move against gravity or applied resistance, using a grading scale ranging from 0 to 5. Higher scores indicate better muscle strength. A score of 0 indicates no visible or palpable muscle contraction; 1 indicates only visible or palpable muscle contraction; 2 indicates joint movement with gravity eliminated; 3 indicates observable joint movement against gravity but not against resistance; 4 indicates joint movement against gravity with some resistance; and 5 indicates joint movement with full resistance against both gravity and applied resistance.
Functional status
时间窗: 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, an average of 11 days, respectively.
Using Postural Assessment Scale for Stroke, and the Barthel scale. The scale consists of 12 items and is scored using a four-point scale (0-1-2-3), with a total score ranging from 0 to 36. Higher scores indicate better postural control and balance function. It primarily assesses two domains: (1) stability of body posture, including static and dynamic balance, and (2) the ability to change body positions, encompa Barthel scale: The scale primarily assesses activities of daily living, including feeding, grooming, toileting, bathing, dressing, bowel and bladder control, transfers between a wheelchair and bed, walking on a level surface or wheelchair propulsion, and stair climbing. The total score ranges from 0 to 100. Scores of 0-20 indicate complete dependence, 21-60 indicate severe dependence, 61-90 indicate moderate dependence, 91-99 indicate slight dependence, and a score of 100 indicates independence. Higher scores reflect better self-care ability and a higher level of independence.
