Lever Wheelchair for People with Physical Impairment – an Alternative Form of Assistive Technology
Journal Title: Niepełnosprawność - zagadnienia, problemy, rozwiązania - Year 2018, Vol 0, Issue 29
Abstract
Background. The aim of this study was to examine differences between lever wheelchair propulsion and handrim wheelchair propulsion on a flat treadmill with different velocity among people with physical impairment. Methods. 20 people with physical impairment, wheelchair users participated in this study. They were asked to move on the wheelchair by levers and by handrims (2 in 1 wheelchair) on the flat treadmill, which was moving with 3.5 km/h and 4.5 km/h for four minutes each drive. Type of pushing was randomly chosen. Minute ventilation (VE), oxygen uptake (VO2), carbon dioxide output (VCO2) as well as heart rate (HR) were observed respectively by ergospirometer K5 Cosmed and by GARMIN sensor. Results. There were significant statistical differences in VE, VO2, VCO2 and HR parameters during lever wheelchair propulsion compare to handrim wheelchair propulsion in each movement on the treadmill (3.5 km/h as well as 4.5 km/h). All measured parameters were lower in lever wheelchair propulsion (p < 0,05). Conclusion. Lever wheelchair propulsion with 3.5 km/h and 4.5 km/h on a flat surface was significantly less demanding in terms of physiological parameters compare to handrim wheelchair propulsion. A lever wheelchair can be easily used as an alternative assistive technology for everyday wheelchair users, also in natural surroundings. There is a need to continue study about lever wheelchair maneuverability as well construction to fully assess this type of wheelchair.
