A field test was performed in El Salvador to evaluate the usefulness of the Shape&Roll prosthetic foot, a foot developed for low-income countries, involving 12 participants. Quantitative gait parameters were measured with a Direct Ultrasound Ranging System (DURS). Qualitative information was obtained from questionnaires administered before and after a three-week trial. The results indicate that the Shape&Roll foot widened the speed range of all participants. According to the questionnaires, the Shape&Roll foot eases walking, enabling participants to walk significantly longer distances. The participants rated its roll-over as very natural and smooth, resulting in a self-perceived reduced walking effort. Handling inclined and uneven surfaces was also rated superior to their current Solid Ankle Cushioned Heel (SACH)-like feet.

Skin adaptation in lower limb amputees assessed through Raman spectroscopy and mechanical characterization.

Following lower limb amputation residuum skin from the lower leg is used to reconstruct the residual limb. Unlike skin on the sole of the foot (plantar skin), leg skin is not inherently load bearing. Despite this, leg skin is required to be load bearing in the prosthetic socket.

Ankle-foot orthoses (AFOs) have been commonly prescribed for stroke survivors with foot drop, but their impact on the contractions of paretic tibialis anterior (TA) and medial gastrocnemius (MG) has remained inconclusive. This study thus investigated the effect of AFOs on these muscle contractions in stroke survivors. The contractions of paretic TA and MG muscles were assessed in twenty stroke patients and compared between walking with and without AFOs, using a novel wearable dynamic ultrasound imaging and sensing system.

Background: Hallux valgus (HV) is a condition characterized by the lateral deviation of the first phalanx and medial deviation of the first metatarsal, leading to subluxation of the first metatarsophalangeal joint. Various orthotic applications are employed in the treatment of HV deformity. This study aimed to compare the effects of a toe separator (TS) and dynamic orthosis (DO) on hallux valgus angle (HVA), plantar pressure (PP), and quality of life (QoL).

Rowing requires both the upper and lower body to be active for balance, steering, and propulsion, constituting a real challenge for athletes with disabilities. To our knowledge, adapted setups allowing pararowing for people with bilateral transfemoral amputation have not yet been described. This case report describes the adapted setup for Mr S, 24 years old, who underwent bilateral transfemoral amputation in 2019 after a motorcycle accident.

The limb amputations caused due to emergent incidents of trauma injuries and vascular diseases currently represent crucial global problems. The patients/amputees with limb amputation who lost the residual limb (knee-ankle foot system) must depend on the prosthetic limb. Prosthetic clinicians and technicians have attempted to develop optimal limb prosthetics that will enhance the ability and functional elements of the patients/users.
