A Modular Functional Electrical Stimulation (FES) System for Gait Assistance in Pediatric Cerebral Palsy

Foot drop, the inability to lift the forefoot during gait, is a common symptom of disorders such as diabetes, stroke, spina bifida, and cerebral palsy. This condition makes walking difficult and unsafe, often resulting in stumbles and falls due to lack of ground clearance. The current standard of care is orthotic bracing, which presents donning and doffing challenges, restricts ankle motion, and contributes to social stigma in many parts of the world. Functional electrical stimulation (FES) is an alternative approach which uses small amounts of electrical current delivered through skin-surface electrodes to stimulate peripheral nerves, thus generating muscle contraction and ultimately functional movement of a human limb. When packaged in a wearable device with onboard sensors capable of detecting gait phase, stimulation current can be applied to the lower leg to cause the foot to lift during the swing phase of gait. While several FES foot-drop systems are commercially available, they cost upward of $13,000 and provide a level of adjustability and complexity not needed for many conditions. The Messiah FES team is working to develop a low-cost, portable, easy-to-use, and durable electrical stimulation device to restore legged ambulation to children with mobility impairments resulting from cerebral palsy, spina bifida, and other conditions with similar effects.

Impacts of Rock Climbing on Lichen and Bryophyte Cliff Communities in the Arid West

Lichens and bryophytes make up the majority of the diversity and cover in cliff systems around the world. Recently, with the rapid rise of rock climbing, there are concerns rock climbers are negatively impacting cliff communities. My study will compare climbed and unclimbed granite cliffs to better understand the impacts of rock climbing on lichen and bryophyte diversity and cover in eastern Washington. The objectives of this study are to assess the impacts of rock climbing on lichen and bryophyte cliff community diversity and cover and improve route development and cliff management practices for lichens and bryophytes. This study will also enhance the flora knowledge of eastern Washington. A conservation strategy will be created with the cooperation of the local Bower Climbers Coalition and the Access Fund of the Pacific Northwest to better manage the impacts of rock climbing on lichens and bryophytes. Recent studies on the impacts of rock climbing have uncovered species of concern and since the flora of cliffs is still very unknown, and rock climbing is on the rise, it is essential more research be conducted
