The effects of dog walking on gait and mobility in people with parkinson disease: A pilot study

Abstract

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 (n = 9) and III (n = 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, p = 0.003, d = 0.77), shorter step length (left: mean difference = 7.11 cm, p = 0.000; right: mean difference = 3.05, p = 0.01), and stride length (left: mean difference = 7.52, p = 0.003; right: mean difference = 8.74, p = 0.001). The base of support was more narrowed (Z = −2.13, p = 0.03), with increased double limb stance time (left: Z = −2.89, p = 0.004; right: Z = −2.59, p = 0.01). Walking with a dog caused slower TUG times (mean difference = −1.67, p = 0.000) and increased number of steps (Z = −3.73, p = 0.000). No significant change shown in step time (left: mean difference = −0.001, p = 0.81; right: mean difference = 0.002, p = 0.77) or cadence (Z = −1.67, p = 0.10). In conclusion, there was an overall decline of gait parameters in people with PD when walking with a dog.
