Comparison of Spatiotemporal and Energy Cost of the Use of 3 Different Walkers and Unassisted Walking in Older AdultsBy Archives of Physical Medicine and Rehabilitation, Vol. 88, No. 6, pp. 768-773

Study conducted to compare temporal, spatial, and oxygen costs during walking among 13 older adults during three conditions: (1) walking without an assistive device; (2) walking with the WalkAbout wheeled walker and (3) walking with two other commercially available assistive devices, including the Merry Walker walker-chair combination. The WalkAbout was designed to address some of the problems associated with the design of the standard walker, as it is both sturdy and adjustable. The design has been tested with 65 older adults who were not able to walk independently in an acute hospital setting and in a nursing home. A total of 95% of the clients reported feeling safe with the device. The Merry Walker is similar to the WalkAbout, though it is not adjustable. Researchers measured gait speed, normalized gait speed, cadence, stride lengths, five-minute walk distance and gait speed, oxygen consumption per meter walked, respiratory exchange ratio per meter walked, and minute ventilation per meter walked during each of the three study conditions. Outcome measures when walking with either the wheeled walker or the WalkAbout did not differ significantly from walking without a device except for a faster cadence with the WalkAbout. Implications for study results are discussed in terms of implications for the prescription of assistive devices for older adults.
