The aim of this pilot study was to compare the vertical reaction forces
(N) generated in three different Action 3 manual one-arm drive wheelchairs: dual
handrim, a lever drive and a Neater Uni-wheelchair (NUW).
A CONFORmat(R) Pressure
measurement mat, placed on top of the users' prescribed cushion, measured
vertical force at the buttock/seat interface on both hemiplegic and
non-hemiplegic sides in each wheelchair. METHODS: Fifteen hemiplegic users were
randomly assigned each wheelchair to drive around an indoor obstacle course.
During propulsion of a multiple sensor, continuous measurement of force was
recorded. Time taken to complete the circuit was recorded. Mean force and
confidence intervals for each buttock were calculated per user per wheelchair.
Results: The dual handrim produced the highest vertical force during propulsion
under the right buttock (x= 484.43; SD = 55.4; p < 0.001) and the lever drive
produced the least force (x= 368.05; SD = 53.55; p < 0.01). The NUW completed the
course quickest (p < 0.01). CONCLUSIONS: The dual-handrim wheelchair requires the
greatest vertical force during propulsion. Since increases in this seat vertical
reaction force may be related to the propulsive force. Further investigation is
indicated as this may be a significant factor for clinicians when prescribing
one-arm drive wheelchairs. Implications for Rehabilitation Review of clinical
reasoning in prescribing wheelchairs. Addition of the Neater Uni-wheelchair to
wheelchair services prescribing lists.
