A wheelchair propelled using a single upper limb offers mobility to individuals with limited or no function in one arm. This adaptation allows users to independently navigate their environment by leveraging a lever system connected to a single drive wheel or a geared mechanism engaging both wheels simultaneously. These mobility devices are frequently customized to meet individual user needs, accommodating varying arm strengths and ranges of motion.
Enhanced independence and self-reliance are among the primary advantages offered by this type of mobility aid. The ability to control movement without assistance can significantly improve quality of life, fostering participation in social activities and increasing access to employment opportunities. Historically, the development of such devices represents a significant advancement in assistive technology, providing increased autonomy to individuals with upper extremity limitations. This design addresses a crucial need for those who might otherwise face significant mobility restrictions.
