Auditory Cue Based on the Golden Ratio Can Improve Gait Patterns in People with Parkinson's Disease.

摘要: The harmonic structure of walking relies on an irrational number called the golden ratio (ϕ): in healthy subjects, it coincides with stride-to-stance ratio, and is associated a smooth gait modality. This smoothness lost people Parkinson's disease (PD), due to deficiencies execution movements. However, external auditory cues seem facilitate movement, by enabling timing muscle activation, helping initiating modulating motor output. Based fractal gait, can administration cue based individual's ϕ-rhythm improve, acute, patterns PD? A total 20 participants (16 males, age 70.9 ± 8.4 years, Hoehn Yahr stage-II) were assessed through stereophotogrammetry: spatio-temporal parameters, computed before, during, after administration. Results show improvements terms stride length (p = 0.018), speed 0.014), toe clearance 0.013) when comparing before stimulus. Furthermore, seems correlate almost all but shows main changes before-during rhythm comparison. In conclusion, effective able compensate for defective internal basal ganglia PD.
