Department Marketplace By APTA Staff | April 2017 OPTP Introduces Knee Glide for Rehabilitative Exercise OPTP has partnered with Robert Schrupp, PT, MA, and Bradley Heineck, PT, to introduce the Knee Glide exercise tool. It facilitates exercise of the lower and upper extremities at home or in the clinic. Patients place their foot or hand on a plate for movement back and forth along the track. Minimal strength is required to move the Knee Glide, making it appropriate for patients who are recovering from knee replacement or other surgeries, hip replacement or fracture, shoulder replacement or other surgeries (such as rotator cuff), or stroke. It comes with a carrying handle that can be used to attach the device to the wall for added stability during shoulder exercises. Schrupp and Heineck have more than 50 years of combined physical therapy experience. In 2011, they started the YouTube channel "Physical Therapy Video" to help educate patients. It now has more than 100,000 subscribers and nearly 20 million views. Aretech Introduces Redesigned ZeroG Gait and Balance System Aretech released Version 3 of its ZeroG Gait and Balance System at APTA's Combined Sections Meeting in San Antonio. The robotic body-weight support system has been redesigned, the company says, and—along with the WaveLink Wi-Fi Guardian—is the only completely wireless system in its class that is not solely dependent on Wi-Fi connectivity. The new design adds dynamic fall recovery with ActiveAssist, which adapts dynamic body-weight support after a fall to help those who need assistance regaining control. The system can support patients weighing up to 450 pounds. For facilities that have 2 ZeroG robotic trolleys on the same track, a "Stealth Detection" feature acts as an invisible bumper to propel the second robot out of the way when it is not in use.
