Abstract

Rehabilitation at home is a growing need worldwide. Previous studies have suggested different devices in terms of motion and force transmission. In this study, we present design and development process of a novel hand exercise exoskeleton. The main advantages of our device that are portable, wearable, light weight (345 grams) and suitable for home use. The greatest feature of the device is the force transmitting mechanism. The spring mechanism manufactured by using commercial compression springs has some advantages in terms of size and weight. In design studies of the device, we have made use of the systematic approach. In this way, the best of three possible design solutions has been determined. Then the best design solution was selected. A few prototypes of the device were manufactured. The device has been tested clinically on both unimpaired individuals and hemiplegic hand patients for a short time. It was reported that the exoskeleton was suited to passive exercises. The result section gives an evaluation of the device in terms of exercises, ergonomics and the market. Additionally, a patent registration certificate was issued to our device for our country.
