LOS ANGELES–(BUSINESS WIRE) – PPS and the authors of the study which led to the creation of Wrist-Aid that alleviates carpal tunnel syndrome (CTS) received both the President’s Research Initiative Award and the Technologists Member Recognition Award – unusual dual recognitions – at the 2017 Annual Meeting of the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) in Phoenix, Arizona, September 13-16.

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 Device for Carpal Tunnel Syndrome

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.

PPS Awarded NIH SBIR Phase II Grant To Develop Wrist-Aid. Wrist-Aid Is A New Device That Alleviates Carpal Tunnel Syndrome (CTS) Symptoms.

June 15, 2017

LOS ANGELES, CA - PPS, a design and development company, was awarded a Small Business Innovation Research (SBIR) Phase II Grant from the National Institutes of Health (NIH) under the National Institute for Biomedical Imaging and Bioengineering (NIBIB). The grant will be used to refine the Wrist-Aid, a new non-obtrusive, non-invasive medical device that alleviates carpal tunnel syndrome (CTS) symptoms without impairment of hand use as with traditional splints.

Carpal tunnel syndrome is a condition where the hand experiences pain, numbness, tingling, and weakness due to chronic compression of the median nerve as it passes through the wrist. It most often develops from repetitive motions that repeatedly compress the median nerve, such as excessive computer or assembly line work. It is also associated with certain conditions that lead to nerve compression.

The cumulative economic cost of carpal tunnel syndrome in the United States is in excess of $2 billion annually. CTS features the second longest average time away from work (28 days) of all major disabling diseases and illnesses in all private industries in the U.S. The Academy of Orthopedic Surgeons’ recommends that non-surgical methods be considered before surgery¹.

After personally suffering from CTS and trying many conservative treatments with limited success, Dr. Jae Son, PPS Founder & CEO, invented Wrist-Aid. When his symptoms went away after wearing the device for only 1 week, Dr. Son realized his product might be able to help others.  Results of a recent pilot clinical study suggest the device relieves CTS symptoms and the improvements continued suggesting longer term benefits.

PPS has assembled a core team of scientific and clinical experts for this grant. The negative pressure and decompression mechanism underlying Wrist-Aid’s treatment principles are consistent with Dr. Zong-Ming Li’s biomechanics research at Cleveland Clinic². Dr. Li is a world renowned hand biomechanist.

When adhered to the wrist, the device pulls up on the tissue under the mid portion of the device. This mechanism relieves pressure on the median nerve leading to relief from CTS.  Understanding the mechanism of how and why this device works is part of the grant objectives. “Our mission is to bring a noninvasive, nonrestrictive, low-cost, and effective treatment to the millions of adults that suffer from CTS" says Dr. Jae Son.
