“…5 For people with LLA, barriers to participation in these programs have been identified. These include musculoskeletal barriers-limitations of the prosthesis and remaining musculature that increase the energy cost of moving [6][7][8] and affect walking, running, and other movement patterns and increase the risk of falling when active [9][10][11][12] ; psychosocial barriers-internal perceptions and those of the wider community, fear of pain, and falling 6,13,14 ; environmental barriers-accessibility and appropriate resources, cost, and specialized equipment; 2,15 and educational barriersknowledge of types of physical activity that are safe to complete and how to adapt exercises to accommodate musculoskeletal issues and residual limb skin blistering and breakdown. 6,15 Previous exercise interventions for PTTA that have been developed are limited to those focusing on developing specific components of fitness and have demonstrated improvements in those targeted components, including cardiovascular endurance 16 and strength.…”

Background: People with transtibial amputation (PTTA) would benefit from increased physical activity levels (PAL) but generic programs developed to support increased PAL do not address the barriers which PTTA experience. Objective: To evaluate the effect of a 12-week training program, developed for PTTA, on their PAL. Methods: Ten PTTA participated in a 12-week training program, which involved one instructor-led supervised group session per week. The program incorporated balance, flexibility, cardiovascular endurance, strength, and agility, as well as educational elements. Personalized starting level and progression intensity were based on the instructor's assessment in the first training session. The effect of the intervention on PAL (self-report questionnaire and accelerometer), fitness, walking symmetry, and adverse effects was determined by analysis of variance before and after the intervention. Results: There was a significant increase in self-reported time in moderate-intensity activity and accelerometer-measured step count and time in movement after the program compared with baseline (p = 0.02). The distance walked in the Six-Minute Walk Test (6MWT) (p < 0.001), time to perform agility test (p = 0.01), and lower-limb strength power (p = 0.01) and endurance (p = 0.01) were significantly greater after the program, and no adverse effects were identified. Conclusions: This study demonstrated an intervention designed specifically for PTTA that can increase PAL.

“…Carbon fiber is a resilient material that is stiffer and around five times stronger than steel. The Principle behind the running blades is that it stores kinetic energy from the user's footsteps as potential energy, as a spring, allowing the users to run and jump [4,5,6]. For example, the Flex-Foot Cheetah is a prosthetic human foot replacement blade developed by biomedical engineer Van Phillips, who had lost a leg below the knee [7].…”

The running blades used by the amputees are an advanced type of prosthesis or prosthetic limb that are used as a replacement for a natural leg. The Principle behind the running blades is that it stores kinetic energy from the user’s footsteps as potential energy, like a spring, allowing the user to run and leap. The major prevailing deficiencies of existing prosthesis are excess weight, lack of Indian manufacturers, high cost quoted by foreign manufacturers, lack of awareness of this technology among the local population. The major purpose of the project is to design and develop an affordable composite blade with unique design, which enables normal walking and running easier for the amputees. The methodology of the project includes selection of suitable composite from glass, carbon and hybrid fibers for blade fabrication through material testing, to evaluate the design using finite element analysis (FEA), to fabricate the actual blades and to analyze the walking pattern of the user’s through gait analysis. Gait analysis results show that with blades the participant is able to follow normal gait pattern of initial contact, mid-stance and toe-off as the blade supports normal knee and ankle biomechanics.
