title: Functional neuromuscular stimulation: outcomes in young people with tetraplegia.
abstract: Percutaneous intramuscular functional neuromuscular stimulation (FNS) systems were fitted to the forearms of five adolescents with tetraplegia in an effort to provide active grasp and release. Two assessments designed at Case Western Reserve University to evaluate functional outcomes of FNS in adults were employed. The common object test (COT) was used to assess hand function during five activities of daily living (ADLs): eating, drinking, writing, brushing teeth and applying toothpaste. A usage survey provided information on the frequency of FNS use in environments outside of the laboratory. In addition, interviews were employed using open-ended questions to gain a deeper understanding of the perceptions of FNS in the adolescents' own environments. Based on the COT results, each adolescent was able to perform ADLs with and without FNS. However, FNS allowed unilateral function so that the extremity without FNS was freed to assist in balance or participate in bilateral tasks. Also, FNS reduced the need for multiple devices, providing users with the potential to perform activities in a variety of environments without transporting adaptive equipment. Those who reported using FNS most often obtained hard-bound school books, held pens during classroom and homework assignments, engaged in leisure activities and performed hygiene tasks. FNS was also used as a means to communicate and socialize through hand gestures. Well-known factors that influence the independence of people with tetraplegia also appeared to affect FNS use.
