“…For example, in regard to age (Kegel et al, 1978;Narang et al, 1984;Steinberg etal, 1985;Holden and Fernie, 1987;Pohjolainen and Alaranta, 1991) and level of amputation (Waters et al, 1976;Kegel et al, 1978;Narang et al, 1984;Steinberg et al, 1985;Holden and Fernie, 1987;Hagberg et al, 1992), most studies showed that younger unilateral trans-tibial amputees got better results. Gender was also studied but did not seem to influence prosthesis use (Steinberg et al, 1985, Helm et al, 1986Pohjolainen and Alaranta, 1991). Some other variables were also explored, such as hand dominance (Kerstein et al, 1977), aetiology (Kegel et al, 1978), physical health (Bachynski and Cumming, 1985;Steinberg et al, 1985;Chan and Tan, 1990;Pohjolainen and Alaranta, 1991), mental health (Pinzur et al, 1988;Hanspal and Fisher, 1991), physical independence (Chan and Tan, 1990), rehabilitation (Steinberg et al, 1985;Beekman and Axtell, 1987;Pohjolainen and Alaranta, 1991), social support (Helm et al, 1986) and length of time since amputation (Kegel et al, 1978).…”
