Three factors impact quality of life for upper limb amputees

NEW ORLEANS — Evolving technology, enhanced patient management and progressive outcome measures are critical factors in the advancement of prosthetic function and the improvement of quality of life for high-level, upper limb amputees, according to research presented at the American Academy of Orthotists and Prosthetists Annual Meeting and Scientific Symposium, here.

John Miguelez, CP, FAAOP, president and senior clinical director at Advanced Arm Dynamics, detailed technological solutions, patient management techniques and outcome measures that could optimize those factors, as well as overall user interaction with the device.

Targeted muscle re-innervation, pattern recognition and implantable myoelectric electrode sensors improve speed, responsiveness and predictability, research showed. Modular prosthetic limb systems also enhance control by offering multiple degrees of control, freedom and high-resolution tactile and position sensing.

Advanced therapeutic services that include household, workplace and community reintegration serve as patient management strategies. Thorough patient surveys and screening allow improved outcome measures and treatment plans.

“In order for us to be more successful in increasing acceptance, we need to work on these things,” Miguelez said. “These are the key factors in achieving our goal, and the goals of our patients.”

Miguelez added that rehabilitation should be a comprehensive effort that assesses planning, prosthesis fit and protocol. If all those points come together, bimanual activity could increase as opposed to reliance on the contralateral limb, increasing user performance exponentially, he said. – by Shawn M. Carter
