Abstract

AlterG treadmills are used for rehabilitation in clinical populations as they can provide up to 80% bodyweight (BW) support, however it is unknown how high levels of unloading might affect spatiotemporal parameters during walking on the AlterG treadmill. 18 healthy adults walked on an AlterG treadmill at 3km/h and 4 km/h at four BW conditions (100, 75, 50, 25%) while wearing Xsens sensors and gait metrics were calculated using the Xsens motion cloud software. Reducing BW in healthy adults via the BW support system on the AlterG treadmill had a small but significant effect on left stance time, swing time and duty factor during walking at 4km/h, but no significant effect on any of the other key spatiotemporal parameters. Therefore, the AlterG treadmill with high levels of BW support can be used for rehabilitation as generally normal gait is maintained.
