The 3D printed prosthetic arm prototype incorporates electromyography (EMG) electrodes, a motor and tendon system, an open-source prosthetic hand design, a custom printed circuit board (PCB), and lithium-ion battery power. The MAP team has completed the design and prototype of a myoelectric prosthesis with a material cost of approximately $1,000 as opposed to the $10,000-$20,000 cost of clinically accepted myoelectric prosthetic upper limbs. The Muscle Activated Prosthesis (MAP) team seeks to reconcile this by creating an affordable, trans-radial, myoelectric prosthesis that utilizes the flexibility of 3D printing technology for a fourteen-year-old congenital amputee named Lily. Sampson, and Tim Howellĭue to the rapid growth of children and the cost of myoelectric technology, children are not given the same opportunities to use myoelectric prosthetics as adults.

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. 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. 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. 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. This condition makes walking difficult and unsafe, often resulting in stumbles and falls due to lack of ground clearance. Farris P.E.&Ph.D.įoot drop, the inability to lift the forefoot during gait, is a common symptom of disorders such as diabetes, stroke, spina bifida, and cerebral palsy. In the fall of 2021, the team partnered with the City of Harrisburg and Capital Region Water to address flooding in the Allison Hill neighborhood of Harrisburg Pennsylvania and designed a plan to mitigate this problem for neighborhood residents.įunding for this work provided by The Collaboratory for Strategic Partnerships and Applied Research.Ī Modular Functional Electrical Stimulation (FES) System for Gait Assistance in Pediatric Cerebral Palsy The system should lessen the erosion affecting the camp road and fix nuisance flooding and erosion at the residences. The design includes collection of the runoff with French drains and rock channels and conveyance of the water through a culvert with discharge down-gradient of affected houses. In the spring of 2022, the team analyzed erosion problems for Greenwood Hills Bible Camp near Chambersburg PA and designed a system to capture and divert the runoff that is causing erosion.
