Abstract

[Purpose] The aim of this study was to investigate three muscle activities of drivers with post-stoke hemiplegia while they were driving using a steering wheel or a spinner knob, and to compare them with those of non-disabled drivers. [Subjects and Methods] The subjects were four non-disabled drivers and five drivers with left hemiplegia. The subjects drove forward in a straight line for 5 m and then turned right or left using the steering wheel or spinner knob with only their right hand. EMG electrodes were placed over the anterior deltoid, biceps and triceps brachii on the right-side. [Results] While differences in muscle activation between the spinner knob and the steering wheel in the control group were not significant, those of the experimental group were significant. Activation of the biceps brachii while the control group turned the vehicle to the right using the spinner knob was significantly lower than when using the steering wheel. Activation of the biceps brachii while the experimental group turned the vehicle to the right using the spinner knob was significantly lower than that of the control group. [Conclusion] The results of this study indicate that a spinner knob requires less activation of the main muscle than a steering wheel, especially in drivers who have had a stroke. The results could be used as basic data when driver rehabilitation specialists prescribe the spinner knob for patients.
