Effect of power-assisted hand-rim wheelchair propulsion on shoulder load in experienced wheelchair users
Compared to hand-rim propulsion, power-assisted propulsion seems effective in reducing potential risk factors of overuse injuries with the highest gain on decreased range of motion of the shoulder joint, lower peak propulsion force on the rim and reduced muscle activity.
A systematic review on the pros and cons of using a push-rim activated power-assisted wheelchair
Power-assisted propulsion might be beneficial for subjects in whom independent hand-rim wheelchair propulsion is endangered by arm injury, insufficient arm strength or low cardiopulmonary reserves. Also, subjects who have difficulty propelling a wheelchair in a challenging environment can benefit from power-assisted wheelchair use.
Participation in community-based activities of daily living: Comparison of a push-rim activated, power-assisted wheelchair and a power wheelchair
Additional knowledge was gained about the benefits of pushrim-activated power-assisted wheelchair technology. Participants were able to continue participating independently in their self-identified community activities using the PPW, and identified comparable ratings of satisfaction and performance with the PPW and the power wheelchair. For some individuals requiring power mobility, the PPW may provide an alternative to the power wheelchair.
Effect of a pushrim-activated power-assist wheelchair on the functional capabilities of persons with tetraplegia
For subjects with tetraplegia, pushrim-activated power-assist wheelchairs have the potential to improve functional capabilities during certain activities of daily living, especially when propelling up ramps, over uneven surfaces, and over thick carpet.
Impact of a pushrim-activated power-assisted wheelchair on the metabolic demands, stroke frequency, and range of motion among subjects with tetraplegia
For subjects with tetraplegia, pushrim-activated power-assisted wheelchairs reduce the energy demands, stroke frequency, and overall joint range of motion when compared with traditional manual wheelchair propulsion.
Evaluation of a pushrim-activated, power-assisted wheelchair
With the pushrim-activated power-assist wheelchair, the user experienced a significantly lower oxygen consumption. Pushrim-activated power-assist wheelchairs may provide manual wheelchairs with a less physiologically stressful means of mobility with few adaptations to the vehicle or home environment.
Mechanical efficiency and user power requirement with a pushrim-activated power-assisted wheelchair
Pushrim-activated power-assist wheelchairs provides on average 73% of the total power when subjects propel with power assistance. Significantly increased efficiency and reduced requirement of user power is achieved using the pushrim-activated power-assist wheelchair. With use, the pushrim-activated power-assist wheelchair may contribute to delaying secondary injuries of manual wheelchair users. In addition, it may be suitable for people who have (or at risk for) upper extremity joint degeneration, reduced exercise capacity, low strength or endurance who currently use electric powered wheelchairs.
Excursion and stroke frequency differences between manual wheelchair propulsion and pushrim activated power assisted wheelchair propulsion
These findings provide the foundation for studying the utility of the pushrim-activated power-assist wheelchair in reducing the risk of upper limb injury and neuropathy in the manual wheelchair user population.
