Comparison of Powered and Unpowered Prostheses in Patients with Transtibial Amputation Walking on a Rock Surface *
نویسندگان
چکیده
Recent research has focused on the design of intelligent prosthetic ankle devices with the goal of adapting the behavior of the device to accommodate all walking surfaces that an individual encounters in daily life. One surface that is particularly difficult for persons with transtibial amputation (TTA) is uneven ground. Patients with TTA have an increased frequency of falling on uneven ground [1], possibly because of limited ankle joint mobility on the prosthetic side, and lack of distal muscles and sensory feedback from the lower limb [2].

Individual Leg and Joint Work during Sloped Walking for People with a Transtibial Amputation Using Passive and Powered Prostheses
People with a transtibial amputation using passive-elastic prostheses exhibit reduced prosthetic ankle power and push-off work compared to non-amputees and compensate by increasing their affected leg (AL) hip joint work and unaffected leg (UL) ankle, knee, and hip joint and leg work during level-ground walking. Use of a powered ankle–foot prosthesis normalizes step-to-step transition work durin...
متن کاملWhole-body angular momentum during sloped walking using passive and powered lower-limb prostheses.
Sloped walking requires altered strategies for maintaining dynamic balance relative to level-ground walking, as evidenced by changes in sagittal-plane whole-body angular momentum (H) in able-bodied individuals. The ankle plantarflexor muscles are critical for regulating H, and functional loss of these muscles from transtibial amputation affects this regulation. However, it is unclear if a power...
متن کاملIncreasing ankle push-off work with a powered prosthesis does not necessarily reduce metabolic rate for transtibial amputees.
Amputees using passive ankle-foot prostheses tend to expend more metabolic energy during walking than non-amputees, and reducing this cost has been a central motivation for the development of active ankle-foot prostheses. Increased push-off work at the end of stance has been proposed as a way to reduce metabolic energy use, but the effects of push-off work have not been tested in isolation. In ...
متن کاملThe AMP-Foot 2.0 : A Powered Transtibial Prosthesis That Mimics Intact Ankle Behavior
Almost all of the transtibial prostheses that are available on the market are purely passive devices. These prostheses store (potential) energy in an elastic element during the controlled dorsiflexion phase of stance and release it right after in order to move the body forward. As a result of this, only the energy which has been stored can be used for push-off and thus for propulsion. There exi...
متن کاملThe effect of a shock-absorbing pylon on the gait of persons with unilateral transtibial amputation.
Shock-absorbing pylons (SAPs) are components that increase prosthetic compliance and provide shock absorption during walking, running, and other high-impact activities in persons with leg amputations. This study investigated the effect of SAPs on the gaits of persons who walk with transtibial prostheses. Two gait analyses were performed on 10 subjects walking with and without an Endolite TT (Te...
