Above-Knee Amputee Gait Takes Another Step

Computerized knee componentry, possibly the major prosthetic technology breakthrough of the last decade, has taken another step forward with the introduction of the Rheo Knee™, a microprocessor-controlled swing and stance system that continuously samples and “learns” the user’s gait pattern and optimizes cadence response. The Rheo Knee thus joins the C-Leg and Adaptive Knee in the growing arena of microprocessor-actuated advanced knee componentry. The Rheo...

Is ‘Prosthetic Parity’ A Good Thing?

Never far from any discussion of advanced prosthetics and orthotics is the companion topic of cost and reimbursement. Like most new products providing new and improved capabilities, breakthrough prosthetic components like the C-Leg, Proprio Foot and Advanced Arm typically come with a hefty price tag and thus may be financially viable for only a small percentage of individuals with congenital or acquired limb loss. Obtaining insurance...

Custom Socket Liners Fill In For Difficult Residual Limbs

The introduction of gel socket liners in the early 1990s opened new vistas of comfort and improved prosthesis suspension for lower-limb amputees and spawned a steady stream of new liner designs and materials, which continues today. Most prosthetic liners are off-the-shelf products of uniform gel thickness throughout and available in various sizes. These products work well for most transtibial and some transfemoral amputees; however, those...

Walter Reed, DARPA Pushing Prosthetic Horizon

Recent componentry breakthroughs like those discussed on this website give testimony to new efforts to develop markedly improved prosthetic solutions for people with congenital and acquired limb deficiencies. As encouraging as these new systems might be, two major research initiatives now underway suggest, “You ain’t seen nothin’ yet!” One program has evolved from efforts to provide a new level of restored function to military personnel...

Designs Enhance Ankle-Foot Orthosis (AFO) Function

Is an ankle-foot orthosis incorporating tone-inhibiting features effective in managing patients with spastic cerebral palsy and other upper motor neuron disorders? There is considerable evidence that abnormal tone in proximal muscle groups can be influenced by joint position and cutaneous stimulation. For cerebral palsy management, maintaining a neutral position of the ankle and subtalar joint and stimulating key reflexogenous areas of the plantar surface (see...
