Vibrotactile Stimulation for Muscle Spasticity

This trial explores whether Vibrotactile Stimulation (VTS), a device that gently vibrates, can help individuals with lower limb spasticity (muscle stiffness) improve mobility and increase walking speed. Researchers aim to identify the optimal body locations for VTS application and determine its effectiveness in easing walking. Participants will use the VTS device during short sessions both at rest and while walking, and they will track their experiences. This trial may suit individuals who have experienced muscle stiffness for at least six months due to a neurological condition and can stand with or without assistance. As an unphased trial, it offers a unique opportunity to contribute to pioneering research that could enhance mobility solutions for many.

The trial does not specify if you need to stop your current medications, but if you are on medications for muscle relaxation, your regimen should be stable. If you are receiving other treatments like physiotherapy, they should have started more than 4 weeks before the trial and remain consistent.

Research has shown that Vibrotactile Stimulation (VTS) is generally safe and easy to use. Studies have found that short-term use of VTS with wearable devices does not cause harm and feels comfortable. No reports of serious side effects or health problems from VTS have emerged. This makes it a safe choice for those looking to reduce muscle stiffness and improve movement. However, users should monitor for any personal discomfort or issues while using the device.¹²³⁴⁵

Researchers are excited about vibrotactile stimulation (VTS) for muscle spasticity because it offers a non-invasive approach that could provide immediate relief. While most treatments for muscle spasticity, like oral medications or injections, often come with side effects or require time to take effect, VTS uses gentle vibrations to target specific muscles and might show benefits within days. This technique could be especially promising for improving mobility and comfort without the drawbacks of traditional therapies. Additionally, VTS's potential to be used both during rest and active movement offers flexible treatment options tailored to individual needs.

Research has shown that Vibrotactile Stimulation (VTS) can greatly reduce muscle stiffness. Studies have found that VTS relieves stiffness and high muscle tone for many people, even those who have tried other treatments like BTX-A. This type of stimulation decreases unwanted muscle spasms in various conditions. For example, VTS effectively reduces neck pain in people with cervical dystonia, a condition that causes neck muscle spasms. Overall, VTS shows promise for improving movement and reducing stiffness, making it a potential option for managing muscle stiffness. Participants in this trial will experience different applications of VTS, including static and dynamic use, to further explore its effectiveness.¹³⁴⁶⁷
