Description

Aim : A research was conducted to investigate the influence by barriers of road surface on the bodily sensation of wheelchair users, while paying attention to “calling” as a factor influencing the comfort of the users. Method : The subjects were chosen from student nurses in their twenties. The objective measurement of the conditions of road surface was carried out through the use of observation, a vibrograph equipped on wheelchairs designed for both self-propelling and attendant-propelling, and a vibration pickup set on the seat of the wheelchairs. In order to grasp the differences emerged from calling in the subjective responses to road surface conditions, the 60 subjects were divided randomly into 2 groups of A and B, the former was “the group with calling（n=30）” whereas the latter was “the group without calling（n=30）”. Ethical consideration : The subjects were explained about the aim and method of the research, and requested to sign the agreement of participation. Analysis method : A comparison between the two groups on the results of the questionnaire was carried out. For the stage assessment of the vibration, fear and feeling of using a wheelchair, the Wilcoxon signedrank test was performed. Results and Discussion : There was a general concordance between the appearance of the road surface and the vibration level, but there were some spots where the vibrational levels were high although the surface appeared to be flat. The followings were the responses to the road surface. 1. Where the vibration levels were high, shakes were caused to the subjects’ bodies and made them feel uncomfortable. 2. Besides vibration, slopes on the road also caused the feeling of fear to the subjects. 3. Calling helped the subjects to predict a vibration and to be ready for it. 4. Calling related to the feeling of relief and mood changes, as well. From those findings, it has been clarified that calling is essential in assisting a wheelchair user. Also, it is a future theme to search for a way to assist in a comfortable use of wheelchairs under various conditions of the road surface.
