Executive Summary

Stroke leaves many survivors with persistent hand impairment, which can have a profoundly negative impact on patients’ functional ability, independence, and quality of life. Basic life activities – e.g. using a fork, reading a book, opening a door handle, etc. – can become frustrating, arduous, or painful, if not impossible. While some patients recover hand function in the weeks, months, or years following a stroke, hand impairment is notoriously difficult to rehabilitate, despite a proliferation of traditional and technology-enabled therapy options that are available. The barriers to engage in such therapies – which can still be time-intensive, painful, arduous, and / or expensive – are often high, limiting the potential for patients to achieve effective rehabilitation results. The result is that the vast majority of patients – 77% of stroke survivors in the U.S. – never completely recover hand function.

The TheraBracelet technology is a clinically proven, patented technology designed to address this need and to democratize access to highly effective hand impairment rehabilitation therapy. Via a wristwatch or bracelet, TheraBracelet delivers an imperceptible vibratory stimulation to the patient’s wrist skin, which increases activity in the areas of the brain that control the movement of the patient’s hand. Unlike other stimulation devices that require the user to wear finger-caps or gloves or other restrictive orthotics, the TheraBracelet’s vibratory stimulation is applied to the wrist via a low-profile device thereby minimizing device interference with hand motion and allowing it to be worn during a rehabilitation session while the patient practices hand tasks. Additionally, because it is easy to use, unobtrusive, and safe, TheraBracelet has the potential to be worn all day, allowing the possibility of home use in conjunction with standard rehabilitation therapy for stroke survivors. All of the above has the potential to help patients maximize their number and duration and ease of treatments, to optimize the delivery of other types of rehabilitation therapy, to allow patients and clinicians to monitor real-life activity levels and rehabilitation progress, and – ultimately – to maximize recovery.
