Abstract

In Indonesia, the Ministry of Health of the Republic of Indonesia (2014) states that the percentage of persons with disabilities who have limitation in walking and climbing up the stairs are 10.26% from the total of disable people. Currently, the equipment which is used frequently is wheelchair, nevertheless, the availability of the wheelchair that fulfill the standard of ISO 7176-5 still deeply limited because it’s pricey and should be imported. In Indonesia, the distributed wheelchair which competes in the commercial market is dominated by Chinese product and some local makers. The purpose of the research is to redesign manual wheelchairs which fulfill the criteria ISO 7176-5. The research is using ISO 7176-5 as a reference design to redesign the main frames of initial wheelchair. The research is begun by comparing and observing 2 types of wheelchairs A and B in commercial market. The 2 wheelchairs (A and B) are measured and compared based on the ISO 176-5 dimension which consists of 27 items. From the measurement and comparison, the wheelchair A is chosen as referenced design because they have more adjustment amount. After that, the dimensions of wheelchair A will be adjusted to ISO 7176-5 and will be tested with Autodesk Inventor software to determine the strength of the main frames. The conclusion of the research is that the result of the suggested frame consist of displacement, von misses stress and safety factor which is revealed as safe. In addition, the dimension of the suggested wheelchair fulfill ISO 7176-5 which guarantees safety and comfort for the users.

Abstract

The investigation stimulates toddlers to learn to walk using a baby walker (BW), allowing the toddler's soles to land on the floor surface. This research compares the effectiveness of using BWstandard and Redesign in stimulating toddlers to learn to walk with Kinect Sensor and Force Sensing Resistor (FSR) devices using video-based biomechanics. This research involved 9 toddlers; the minimum age of toddlers was 9 months, body length 70-80cm, and foot length 10-12cm. The biomechanics of toddlers on leg compression are performed via video in real-time using Kinect Sensor with movement analysis developed through Microsoft Visual Studio Software and Vitruvius Software. Measuring foot pressure using FSR is connected to the Arduino IDE system and placed in the prewalker sock via 5 reading points. Statistical tests use paired sample t-tests. Toddler foot compression force using BWstandard (Redesign), heel-strike phase 218.98 N (447.66 N), midstance phase 273.08 N (462.61 N), toe-off phase 181.94 N (371.99 N), and foot pressure 248 N (339 N). The results of the Pair sample t-test showed that there was a difference in use between BWstandard and Redesign. It was concluded that stimulation of toddlers learning to walk was achieved more effectively using BWredesign and was more recommended.
