The purpose of this study was to develop a single-handed driving sports-specific wheelchair in order to improve a driving performance. To perform the purpose, NSB-07 for wheelchair basketball made by the Nisshin Medical Industries Company Limited was improved to a double ring typed single-handed driving sports-specific wheelchair. Two universal joints were used to transmit revolution of handrim in drive wheel. Furthermore, the EMGs from upper limb and the revolution velocity of handrim were measured when the wheelchair mentioned above was driven only one stroke by four driving ways which were double-handed driving, single-handed driving on both handrims, single-handed driving on handrim of left drive wheel, and single-handed driving on handrim of right drive wheel. In the result, It was indicated that a single-handed driving sports-specific wheelchair was have high driving performance by iEMGs of pectoralis major, biceps brachii, and anterior deltoid and revolution velocity of handrim on four driving ways.
