Brief Summary

The aim of this study was to identify the assistance effect of the new wearable hip assist robot, gait enhancing mechatronic system (GEMS) developed by Samsung Advanced Institute of Technology (Samsung Electronics Co, Ltd., Korea) during stair ascent by comparing the energy expenditure of elderly adults with and without the GEMS.

Conditions

Gait, Unsteady; Health Behavior

Keywords

Wearable hip assist robot; Elderly adult; Metabolic energy expenditure; Stair ascent

Outcome Measures

Primary Outcomes (1)

• Change on metabolic energy expenditure in GEMS condition compared with NoGEMS condition

  All participants stood in a comfortable position for 5 minutes to obtain baseline variables before stair ascent. Participants were then asked to climb stairs from the first basement level to the fourth floor of the Proton Therapy Center, Samsung Medical Center, Korea, in a step-over-step manner under two different conditions, GEMS and NoGEMS. The GEMS and NoGEMS conditions were conducted in a random order, and just before the second condition, participants stood for 2～3 minutes to obtain baseline variables once more.

Elderly adults

EXPERIMENTAL

Stair climbing with and without a wearable hip assist robot

Device: Wearable hip assist robot

Interventions

Wearable hip assist robot DEVICE

All participants climbed stairs from the first basement level to the fourth floor of the Proton Therapy Center, Samsung Medical Center, Korea with and without a wearable hip assist robot. During climbing stairs, the metabolic energy expenditure of all participants was measured using a portable cardiopulmonary metabolic system (Cosmed K4b², Rome, Italy).
