“…No differences in strength were found between those who were amputated over seven years ago and those who were amputated more recently. 19 From these studies it was concluded that muscle force is reduced after amputation. Except for the study of Isakov et al, 19 no data on the development of strength during rehabilitation was found (Table 4a).…”

Objective: To review the influence of physical capacity on regaining walking ability and the development of walking ability after lower limb amputation. Design: A systematic search of literature was performed. The quality of all relevant studies was evaluated according to a checklist for statistical review of general papers. Subjects: Lower limb amputees. Main measures: Physical capacity (expressed by aerobic capacity, anaerobic capacity, muscle force, flexibility and balance) and walking ability (expressed by the walking velocity and symmetry). Results: A total of 48 studies that complied with the inclusion criteria were selected. From these studies there is strong evidence for deterioration of two aspects of physical capacity (muscle strength and balance) and of two aspects of walking ability (walking velocity and symmetry) after lower limb amputation. Strong evidence was found for a relation between balance and walking ability. Conclusion: Strong evidence was only found for a relation between balance and walking ability. Evidence about a relation between other elements of physical capacity and walking ability was insufficient. Training of physical capacity as well as walking ability during rehabilitation following lower limb amputation should not be discouraged since several parameters have been shown to be reduced after amputation, although their relation to regaining walking ability and to the development of walking ability remains unclear.

“…14,15 In the long term, there may be changes related to localized muscle atrophy and altered mechanics of mobilization. [16][17][18] Psychological, social and sexual issues also impact significantly on the overall function of the person with an amputation, but are currently, generally managed less well than physical or functional issues. 19 Persons with amputation may experience a wide range of activity limitations and participation restrictions.…”

Amputation is a common late stage sequel of peripheral vascular disease and diabetes or a sequel of accidental trauma, civil unrest and landmines. The functional impairments affect many facets of life including but not limited to: Mobility; activities of daily living; body image and sexuality. Classification, measurement and comparison of the consequences of amputations has been impeded by the limited availability of internationally, multiculturally standardized instruments in the amputee setting.

“…[14][15][16] After unilateral transtibial (TT) or transfemoral (TF) amputations, muscle atrophy and a reduction in muscle strength are commonly observed in the residual amputated limb, which is weaker than the intact leg. [15][16][17][18][19][20][21] Interestingly, in sports active TT amputees, hip strength of the residual leg was found to be increased and stronger than for the intact leg and also stronger than in able-bodied athletes. 22 These data suggest that, in order to achieve good walking ability, additional hip strength at the amputated leg is needed to compensate for the loss of leg function caused by the amputation.…”

Background: Little data have been reported on the factors that are important in bilateral amputee walking ability especially the role of hip strength. Study Design: Observational, case-control study where participants were evaluated at a single point in time.Objectives: The aim of this study was to investigate the factors involved in bilateral amputee walking ability by assessment of walking speed, perceived exertion, exercise intensity, physiological cost index (PCI) and hip muscle strength. Methods: For a group of 10 bilateral amputees, with different levels of amputation, and a non-pathological reference group, walking ability was assessed using the two-minute walk test. Hip muscle strength was assessed using isokinetic strength tests. Results: Bilateral amputees were found to have slower walking speeds and increased PCI of walking which were correlated to higher levels of amputation. Peak hip torques were reduced in the amputees, which was only significant for concentric extension torque (p = 0.029), and approaching significance for concentric flexion (p = 0.061) and abduction (p = 0.057). Bilateral amputee peak hip strength suggested a positive trend with increasing walking ability. Conclusions: Bilateral amputee walking ability was reduced and mainly related to level of amputation. The role of hip strength in bilateral amputee walking ability requires further investigation. Clinical relevanceIn bilateral amputee prosthetic rehabilitation, amputation levels are a key factor in walking ability. Besides level of amputation, and assuming general fitness, hip strength may be a key factor in achieving functional walking mobility as a bilateral amputee.
