Because of this recognition, the abstract describing the study and
Wrist-Aid will be published in the Muscle & Nerve Journal, a
prestigious publication in the medical industry.

Carpal tunnel syndrome (CTS) is one of the most widely recognized
occupational health conditions. In the US, it affects 3-6% of working
adults. A quarter to half a million people undergo carpal tunnel release
surgery each year.

Wrist-Aid is a simple unobtrusive device that sticks to the underside of
the wrist. The device applies a negative pressure to the affected
region, pulling up on the tissue under the mid portion of the device,
thus reducing compression and irritation. The
results of the pilot clinical study
suggest the device relieves CTS
symptoms without the trauma of surgery or impairment of hand use as with
traditional splints.

"I invented Wrist-Aid after suffering from CTS and trying many other
conservative treatments without success. After it relieved my symptoms,
I felt compelled to bringing this noninvasive, low-cost solution to
millions of adults that currently suffer from CTS," said Dr. Jae Son,
PPS Founder & CEO.

Wrist-Aid was investigated in a pilot clinical study (ClinicalTrials.gov
ID NCT02534493
) involving 11 CTS patients. Participants wore
Wrist-Aid for 8-10 hours daily for 4 weeks. The average raw improvement
in Boston Carpal Tunnel Questionnaire (BCTQ) Symptom Severity Scale
(SSS) at the 4-week time point is 0.59. (The SSS is a scale from 1 being
no symptoms to 5 being the worst symptoms.) The average raw improvement
in SSS at the 12-week time point is 0.72. Unilateral patients reported
an average improvement in symptom severity of 0.9 points at 4 weeks and
1.2 points 8 weeks post-treatment. For comparison, other studies have
found surgery produces a raw improvement in SSS of 0.8 to 1.5 three
months after surgery.

"Our Hand Research Laboratory in partnership with PPS recently received
a NIH SBIR Phase II grant to conduct further research and development on
Wrist-Aid. PPS leads the development and commercialization while our
laboratory carries out scientific studies to investigate the therapeutic
mechanisms and further validate the efficacy of Wrist-Aid for CTS
patients," said Dr. Zong-Ming Li, Professor in Biomedical Engineering,
Orthopaedic Surgery, and Physical Medicine and Rehabilitation at
Cleveland Clinic.
