Research Evidence

Aim: To investigate the feasibility and effectiveness of an origami-based gravity support device with integrated triboelectric nanogenerators (TENGs) for shoulder rehabilitation, utilizing exercise gaming and energy harvesting functionalities.

Method: Experimental and quasi-experimental study with a pilot user trial.

Procedure: An origami structure was designed to provide gravity support for the shoulder. Triboelectric nanogenerators (TENGs) were integrated into the structure to act as self-powered sensors for exercise gaming and as energy harvesters. A pilot study was conducted with three stroke patients who performed rehabilitation tasks (a table-tennis game and an energy harvesting exercise) using the device. Range of motion (ROM) was measured, and patient feedback was collected.

Sample Size: 3 participants

Context: Medical rehabilitation, assistive technology, wearable sensors, energy harvesting.

Design Principle

Integrate energy harvesting and sensing into assistive devices to enhance functionality and user engagement.

How to Apply

When designing assistive devices for rehabilitation, consider incorporating self-powered sensing for interactive feedback and gamification, and explore energy harvesting to reduce external power dependencies.

Limitations

Small sample size, limited scope of rehabilitation tasks, and the need for further validation of long-term effectiveness and durability.
