What You Need to Know Before You Apply

What is the purpose of this trial?

The objective of this study is to determine if combining vibration with hand task practice is superior to hand task practice alone.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you've changed spasticity medication or had a botulinum toxin injection in the last 3 months.

Is the TheraBracelet safe for use in humans?

The TheraBracelet, a wrist-worn device providing low-level vibration, was tested in stroke survivors and found to be generally safe for daily use over a month. Some mild adverse events, like worsened sensory scores, were reported, but they were not consistently linked to the device.12345

How is the TheraBracelet treatment different from other stroke recovery treatments?

The TheraBracelet treatment is unique because it uses a wrist-worn device to provide imperceptible vibratory stimulation during hand tasks, allowing for continuous sensory stimulation without interfering with natural movements. This approach contrasts with other methods that require separate time commitments and may disrupt hand activities.12467

What data supports the effectiveness of the treatment Concomitant Sensory Stimulation, TheraBracelet, Concomitant Sensory Stimulation for stroke recovery?

Research suggests that sensory stimulation, like that provided by TheraBracelet, can be safe and may help improve recovery in stroke survivors by enhancing motor and sensory functions. Although more studies are needed, similar treatments have shown potential benefits in improving outcomes for stroke patients.26789

Are You a Good Fit for This Trial?

This trial is for adults over 18 who had a stroke at least 6 months ago and have difficulty with hand tasks. They must be able to follow instructions and not be on certain spasticity medications or undergoing other upper limb therapies. Severe spasticity, skin issues at the wrist, or other conditions affecting arm function disqualify them.

Inclusion Criteria

It has been over 6 months since my stroke.
I can complete hand tasks quickly, in less than 120 seconds.
Your average time to complete the Wolf Motor Function Test is more than 10 seconds.

Exclusion Criteria

I haven't changed my spasticity medication or had a botulinum toxin injection in my arm in the last 3 months.
I am currently receiving therapy for my arm.
I have a health condition that affects my arm's ability to move or feel.

What Are the Treatments Tested in This Trial?

Interventions

  • Concomitant Sensory Stimulation
Trial Overview The study is testing if adding vibration to regular hand exercises helps improve hand function better than just doing the exercises alone after a stroke. Participants will either receive real vibration stimulation or no stimulation while practicing hand tasks.

Published Research Related to This Trial

A systematic review of 8 studies on active sensory interventions for post-stroke upper limb recovery found that techniques like mirror therapy and motor imagery show promise, but strong evidence for their effectiveness in improving motor recovery is lacking.
The review highlights the need for a comprehensive active sensory protocol that combines cognitive, sensory, motor, and functional elements, and calls for high-quality randomized trials to better evaluate these therapies.
Active Sensory Therapies Enhancing Upper Limb Recovery Among Poststroke Subjects: A Systematic Review.Arya, KN., Pandian, S., Joshi, AK., et al.[2022]
Early sensory stimulation within the first 6 hours after an ischemic stroke may have significant effects on recovery, with preclinical studies showing both neuroprotective benefits and potential increases in infarct volumes by 30-50%.
Understanding the impact of acute sensory stimulation is crucial, as stroke patients often experience uncontrolled sensory inputs during transport and treatment, highlighting the need for further research in this area.
Sensory stimulation in acute stroke therapy.von Bornstädt, D., Gertz, K., Lagumersindez Denis, N., et al.[2023]
The TheraBracelet, a device providing low-level vibration, was found to be safe for chronic stroke survivors when worn for over 8 hours a day for 2 months, with fewer adverse events reported during the real stimulation month compared to the sham month.
Out of 25 participants, only 24% experienced mild adverse events, indicating that prolonged sensory stimulation does not significantly worsen hand function or sensation, suggesting it could be a beneficial tool for rehabilitation.
