“…Research has identified lower limb weakness from various aetiologies as a major intrinsic contributor (Janken et al, 1986;Morse et al, 1987;Byers et al, 1990;Salgado et al, 1994). Abnormalities of gait and balance (Tinetti et al, 1986;Barclay, 1988;Stalenhoef et al, 1997;Stevenson et al, 1998), neurological pathologies such as Parkinson's Disease (Dolinas et al, 1997;Ashburn et al, 2001), primary diagnosis of stroke and amputation (Barr, 1999) have been implicated. Visual contrast sensitivity, proprioception in the lower limbs, quadriceps strength, reaction time and sway on a foam rubber surface with the eyes open significantly discriminated multiple falls from a single fall or no falls (Lord et al, 1994).…”
