dc.description.abstract | Objectives: This study examined if people with Parkinson’s and freezing of gait pathology (FoG) could be trained to increase preparatory weight-shift amplitude, and facilitate step initiation during FoG. Methods: Thirty-five people with Parkinson’s and FoG attempted to initiate forward walking from a stationary position caused by a freeze (n=17, FoG-F) or voluntarily stop (n=18, FoG-NF) in a Baseline condition and two conditions where an increased weight-shift amplitude was trained via: i) explicit verbal instruction, and ii) implicit movement analogies. Results: At Baseline, weight-shift amplitudes were smaller during: i) unsuccessful, compared to successful step initiations (FoG-F group), and ii) successful step initiations in the FoG-F group compared to FoG-NF. Both Verbal and Analogy training resulted in significant increases in weight-shift amplitude in both groups, and a corresponding pronounced reduction in unsuccessful attempts to initiate stepping (FoG-F group). Conclusions: Hypometric preparatory weight-shifting is associated with failure to initiate forward stepping in people with Parkinson’s and FoG. However, impaired weight-shift characteristics are modifiable through conscious strategies. This current study provides a novel and critical evaluation of preparatory weight-shift amplitudes during FoG events. The intervention described represents an attractive ‘rescue’ strategy and should be further scrutinised regarding limitations posed by physical and cognitive deficits. | en_GB |
