The Effects of Dog Walking on Gait and Mobility in People with Parkinson Disease: A Pilot Study

摘要

The objective of this study was to assess the effects of dog walking on gait and mobility in people with Parkinson disease (PD). This single-group, single-session, observational pilot study included nineteen participants with PD in Hoehn and Yahr stages II ( = 9) and III ( = 10). Primary measures were a gait analysis and the Timed Up and Go (TUG). Three trials of two conditions (walking with and without a dog) were completed. Walking with a dog resulted in slower gait velocity (mean difference = 0.11 m/s, = 0.003, = 0.77), shorter step length (left: mean difference = 7.11 cm, = 0.000; right: mean difference = 3.05, = 0.01), and stride length (left: mean difference = 7.52, = 0.003; right: mean difference = 8.74, = 0.001). The base of support was more narrowed (Z = −2.13, = 0.03), with increased double limb stance time (left: Z = −2.89, = 0.004; right: Z = −2.59, = 0.01). Walking with a dog caused slower TUG times (mean difference = −1.67, = 0.000) and increased number of steps (Z = −3.73, = 0.000). No significant change shown in step time (left: mean difference = −0.001, = 0.81; right: mean difference = 0.002, = 0.77) or cadence (Z = −1.67, = 0.10). In conclusion, there was an overall decline of gait parameters in people with PD when walking with a dog.
