abstract="The distance one can walk at a time could be considered an important functional  outcome in people with a lower limb amputation. In clinical practice, walking  distance in daily life is based on self-report (SIGAM mobility grade (Special  Interest Group in Amputee Medicine)), which is known to overestimate physical  activity. The aim of this study was to assess the number of consecutive steps and  walking bouts in persons with a lower limb amputation, using an accelerometer  sensor. The number of consecutive steps was related to their SIGAM mobility grade  and to the consecutive steps of age-matched controls in daily life. Twenty subjects  with a lower limb amputation and ten age-matched controls participated in the  experiment for two consecutive days, in their own environment. Maximal number of  consecutive steps and walking bouts were obtained by two accelerometers in the left  and right trouser pocket, and one accelerometer on the sternum. In addition, the  SIGAM mobility grade was determined and the 10 m walking test (10 MWT) was  performed. The maximal number of consecutive steps and walking bouts were  significantly smaller in persons with a lower limb amputation, compared to the  control group (p < 0.001). Only 4 of the 20 persons with a lower limb amputation had  a maximal number of consecutive steps in the range of the control group. Although  the maximal covered distance was moderately correlated with the SIGAM mobility grade  in participants with an amputation (r = 0.61), for 6 of them, the SIGAM mobility  grade did not match with the maximal covered distance. The current study indicated  that mobility was highly affected in most persons with an amputation and that the  SIGAM mobility grade did not reflect what persons with a lower limb amputation  actually do in daily life. Therefore, objective assessment of the maximal number of  consecutive steps of maximal covered distance is recommended for clinical treatment.<p /> <p>Language: en</p>",
