Overview
Brief Summary
To address muscle weakness, sensory degradation, functional decline, and pain caused by geriatric syndromes in older adults and stroke survivors, this project proposes a series of studies aimed at improving neuromuscular performance, muscle strength, proprioceptive gain, functional outcomes, and pain relief through the use of a precise vibration system.
In the first phase, a vibration exercise system will be implemented to recruit frail older adults and older adults with stroke for clinical trials. The goal is to verify the benefits of vibration intervention on limb muscle strength, proprioception, and movement function.
In the third phase, quantitative pain assessments and related scales will be used to evaluate chronic pain thresholds and affected regions in older adults and stroke survivors, and to validate the effectiveness of vibration intervention in alleviating their pain.
Study Design
- Study Type
- Interventional
- Allocation
- Randomized
- Intervention Model
- Parallel
- Primary Purpose
- Treatment
- Masking
- Triple (Participant, Investigator, Outcomes Assessor)
Masking Description
The outcomes assessor will be blinded to participants' group allocation to reduce assessment bias.
