Evaluation of a Soft Exoskeleton to Support Forward Leaning and Lifting

Summary

In this study the LiftSuit version 2.0 designed by Auxivo AG will be used. The LiftSuit is a soft wearable device that is designed to support workers perform physically demanding tasks including repetitive lifting and working in forward leaning positions. It is put on like a backpack and attached to the body using fabric bands and cuffs. Besides soft fabric parts the LiftSuit contains elastics elements. The elastic elements can be flexibly exchanged by the experimenter. For this experiment elastic elements of known stiffness will be hooked into the fabric frame.

• Occupational Exposure

Interventions

DEVICE

Placebo LiftSuit Exoskeleton

The LiftSuit is a soft passive wearable device that is designed to support the hip and back muscles during forward leaning and lifting. It exerts it function through Elastic Energy Storages (EES). In this condition the EES are removed from the device to create a placebo device.

DEVICE

LiftSuit Exoskeleton (low support level)

The LiftSuit is a soft passive wearable device that is designed to support the hip and back muscles during forward leaning and lifting. It exerts it function through Elastic Energy Storages (EES). EES of different three different levels of stiffness (low, medium, high stiffness) will be used.

DEVICE

LiftSuit Exoskeleton (medium support level)

The LiftSuit is a soft passive wearable device that is designed to support the hip and back muscles during forward leaning and lifting. It exerts it function through Elastic Energy Storages (EES). EES of different three different levels of stiffness (low, medium, high stiffness) will be used.

DEVICE

LiftSuit Exoskeleton (high support level)

The LiftSuit is a soft passive wearable device that is designed to support the hip and back muscles during forward leaning and lifting. It exerts it function through Elastic Energy Storages (EES). EES of different three different levels of stiffness (low, medium, high stiffness) will be used.
