About this study

There remains challenging for improving functional recovery of stroke patients in the acute post-stroke period among patients with acute stroke. Particularly the effectiveness of early rehabilitation combining with vibration training for patients with acute stroke is unknown.

Therefore, this study aims to exam the effectiveness of vibration training on muscle strength of lower limbs, functional recovery, and mood state among patients with acute stroke.

A randomized controlled trial will be conducted. Patients with acute ischemic stroke will be selected and randomly assigned to either control group (CG), exercise group (EG), wearable leg vibration training group (WG), or lower extremity vibration training group (LG). All groups will receive conventional treatment and regular rehabilitation. Neurologic disability (Modified Rankin Scale), muscle strength, functional status (Postural Assessment Scale and Barthel Scale), and mood state (Hospital Anxiety and Depression Scale) will be collected to compare between groups and pre- and post-differences.

Treatment and study plan

vibration training

Device

The vibration sessions were performed and supervised by a stroke care experienced registered nurses/researchers who had both nurse and physiotherapist license. The wearable leg vibration training with vibration frequency = 30 Hz, vibration amplitude = 1 mm in the WG was applied by the wearable leg vibration device (Myovolt, New Zealand) which fits comfortably around the knee and hamstring or calf and delivers focal vibration treatment. While the lower-extremity weight bearing vibration training with vibration frequency = 20 Hz, vibration amplitude = 3 mm in the LG was applied the Cozy Fit (HY-806, China) vibration device with vertical direction, which participants stand with both feet upright on the vibrator in a seated position.

Primary outcomes

  1. neurologic disability

    Time frame: Baseline

    neurologic disability will be assessed by Modified Rankin Scale, which scores are ranged from mRS: 0 (no symptoms) to 6 (death) and score 5 indicates a severe disability: requires constant nursing care and attention, bedridden, and incontinent.

  2. neurologic disability

    Time frame: 5 days after intervention

    neurologic disability will be assessed by Modified Rankin Scale, which scores are ranged from mRS: 0 (no symptoms) to 6 (death) and score 5 indicates a severe disability: requires constant nursing care and attention, bedridden, and incontinent.

  3. neurologic disability

    Time frame: through hospitalization, an average of 14 days

  4. muscle strength

    Time frame: Baseline

    The reliable and well-validated Medical Research Council Manual Muscle Testing scale, the most commonly accepted method of evaluating muscle strength and easy to perform, will be adopt to evaluate muscle strength. The scale assesses the lower-limb muscle strength of both affected and unaffected side by measuring the resisting gravity load and against the examiner's resistance. The test is scored on a scale of 0 - 5, with 0 indicating the worst muscle strength where no muscle contraction is observed, 1 indicating slight muscle contraction but no limb movement, 2 indicating parallel limb movement but no gravity resistance or lifting, 3 indicating limb movement against gravity, 4 indicating limb movement against slight resistance, and 5 indicating limb movement against moderate resistance.

  7. Functional status: Postural Assessment Scale for Stroke

    Time frame: Baseline

    The Postural Assessment Scale for Stroke, consisting of two parts with a 4-point scale and a total score ranging from 0-36, is a well-validated assessment tool for postural control in patients with stroke during the first 3 months after stroke. The PASS will be used to evaluate patient's ability to either maintain posture (including static and dynamic balance) or change posture (switching between lying, sitting, and standing) and participants with higher scores represent a better functional status.
