Welcome to the Alber clinical resource page. We’ve pulled together some of the best research in the industry around Power Assist.
April, 2020
Features information about the benefits of power assist in reducing strain on muscles and joints and giving end users the extra power they need to extend their day.
October, 2015
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.
September, 2012
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.
September, 2008
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.

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.
November, 2004
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.
May, 2001
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.
January, 2001
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.
January, 2000
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.
