Objectives: The purpose of this study was to investigate the effects of assist and resistance torque using a Gait Enhancing and Motivating System (GEMS) 1) on the spatiotemporal gait characteristics, and 2) on the symmetry and asymmetry of gait in the elderly.
Methods: A cross-sectional and repeated measure design was used. A total of 18 participants (9 males, 9 females; age: 63.5 ± 5.02 years; mass: 64.26 ± 6.87 kg; height: 164.06 ± 7.15 cm) were recruited from a local community, and spatiotemporal gait data were collected with OptoGait system and GEMS. Spatiotemporal gait variables and differences between the dominant and non-dominant legs of these variables were assessed (step length, step time, stance phase, swing phase, single support, load response, pre swing phase, stride time, stride length, double support, cadence, and gait speed). The effects of three modes including normal, assist, and resist modes using GEMS were investigated twice for each participant on a 9-meter walkway. A one-way repeated measure analysis of variance followed by Bonferroni post-hoc tests was conducted.
Results: The key findings were 1) assist mode increased step time, swing phase, stride time and reduced stance phase, pre-swing phase, double support, cadence, and gait speed as compared to normal mode; 2) resist mode increased stance phase, load response, pre-swing phase, double support, cadence, and reduced step time, swing phase, and stride time; 3) both in dominant and non-dominant leg, assist mode showed increased step time and reduced pre-swing phase than normal mode, and greater step time than resist mode (p < 0.05), and 4) there was no effect of external torque on symmetry and asymmetry between both legs (p > 0.05).
Conclusions: The GEMS may be a useful tool for the gait training program for elderly individuals. Resistance and assist torque, and the combination of these can effectively promote gait function.
