Abstract

The skeletal, muscular and nervous systems in human body works together to enable specific movement or posture. Abnormalities in any of these systems may cause this functionality to degrade. Some examples of such diseases are spinal muscular atrophy and celebral palsy. Patients who suffer from these diseases may require assistive devices designed specifically to their anatomy for supporting their posture and mobility. Bioteknik Design in Bandung, is a small local company focusing in the development of assistive device for helping such patients. A collaboration between SGU and Bioteknik was made to help Bioteknik in designing some of their supportive devices. A student internship was assigned in Bioteknik Design to conduct various tasks related to developing assistive devices based on the need of the patient. These tasks include patient anatomy measurement, design and production of the assistive devices suitable for the patient. These tasks are directed towards giving the patient the mobility and the posture needed, so that the opportunity for the patient to move, explore, and connect to their surroundings could be improved. In this project, several assistive devices, e.g. electrical wheelchair (Go-Roll), specific wheel chair with footrest, and feet-controlled wheelchair, have been measured, design and implemented at various stages.

Abstract

Spinal Muscular Atrophy or SMA disorder is generally thought to have affected as many as 1 in 40 in country like USA. SMA type 2 and 3 are commonly found in Indonesia. Children who suffer from SMA disease cannot move their hands with flexion - extension and abduction - adduction orientation maximally, because the muscles in the patient cannot support the movements of the hand. In this project, an initial joint effort was conducted by SGU and Bioteknik Design, to develop an active mechanical arm support with muscular feedback. Hence, the hand movements of the patient can be supported externally through detecting the muscle tension produced by moving the patient's hand. The tension is detected using Carbon Nanotube (CNT)-coated thread Mechanomyography (MMG) sensor. The sensor signal is then fed into Arduino microcontroller, to give appropriate control signal to the universal power window motor. As an early proof of concept, wood was used as the main structural material for the arm support. The project, however, did not go as expected due to the lack of torque from the motor and missed feedback connection from the sensor. A counter balance mechanism like spring may be attached for future improvement.
