Ergonomic study of X-L wheelchair.

Wheelchairs have been used widely as the one of the vehicles that are designated purposely to help the disabled patient to easily move around. However, the standard wheelchairs currently available in the market are mostly fit to patients which have average size and can only accommodate the patient with maximum body mass up to 100kg. When a big size or extra-large (XL) patient with body mass more than 100 kg uses this standard wheelchair, they may feel discomfort, cramped as well as restricted movement. Furthermore, the structure of standard wheelchairs may not be safe enough to hold the load of big size patient weight. Therefore, this project is focused to study the appropriate an ergonomic body sizes and dimensions of big patients that body mass ranging from minimum 100kg to maximum 150kg. The investigation is focused on the customer needs as well as anthropometry body measurements. The data was collected from the questionnaires and direct interview among 30 personnel with the body mass in target range. The information gathered then had been used to custom design the XL wheelchair that fulfil the most requirements and having sturdy structure that safety to be used. [ABSTRACT FROM AUTHOR]
