Could a gentle buzz boost strength and ease pain in aging and stroke?
NCT ID NCT07351877
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a special vibration device, used along with standard rehab, can improve muscle strength, movement, and pain in older adults and stroke survivors. About 80 participants will receive either vibration therapy plus rehab or rehab alone. The goal is to see if the vibration helps with balance, walking, and daily function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Precision vibration therapy device
- What this could lead to
- If it works, this could offer a simple, non-drug way to improve strength, balance, and reduce pain in older adults and stroke survivors.
- What could go wrong
- This is an early-stage study with only 80 participants, so results may not apply to everyone. The benefits of vibration therapy are still unproven, and individual responses may vary.

Inclusion Criteria: Older Adults: * Meet two or more criteria of the Study of Osteoporotic Fractures (SOF) frailty index * Willing to participate in the study and comply with all study procedures * Able to wear and safely use the vibration device * Normal cognitive function (Mini-Mental State Examination \[MMSE\] score ≥ 23) * Presence of knee joint pain in the lower limbs Stroke Survivors: * Clinical diagnosis of ischemic or hemorrhagic stroke confirmed by a physician * Clinically stable stroke condition (i.e., not in an acute or unstable phase) * Brunnstrom stage ≥ III for the affected limb * Cognitive ability sufficient to follow study procedures (MMSE score ≥ 23) * Modified Ashworth Scale (MAS) score \< 3 for the paretic limb * Able to sit safely and participate in vibration or rehabilitation sessions for up to 60 minutes per visit * Willing and able to comply with all study procedures and provide written informed consent Exclusion Criteria: Older Adults: * Acute or chronic neurological injury involving the upper or lower limbs within the past 6 months * Acute or chronic musculoskeletal injury involving the upper or lower limbs within the past 6 months * History of surgery on the upper or lower limbs within the past 6 months Stroke Survivors: * Recurrent stroke during the current episode (i.e., acute re-stroke) or otherwise clinically unstable stroke presentation * Markedly elevated spasticity preventing isolated voluntary movement of the target limb (MAS score ≥ 3) * Hemianopsia or severe hemineglect that significantly interferes with task execution * Concomitant vestibular or cerebellar disorders that severely impair motor performance * Orthopedic or traumatic comorbidities causing significant pain or limiting safe participation during evaluation or intervention * Cognitive impairment attributable to stroke that precludes effective communication or adherence to the study protocol * Other neurological or psychiatric disorders judged likely to interfere with motor performance or study outcomes
