dc.description.abstractProblem: Although several assessments are available to document balance, only a limited number are able to sufficiently document multi-directional decline in dynamic balance in persons with Parkinson's Disease (PPD). Purpose: Identify clinical metrics to track changes in motor coordination over time using an instrumented Four-Square Stepping Test (iFSST) to document decomposition variables of performance for PPD. Design: Exploratory Case - Control Methods: Volunteers were PPD at least 18 years of age, a Hoehn Yahr stage 1-3, able to walk at least 10 meters with/without assistive device and perform a four-square stepping task using forward, sideways and backwards stepping into squares 1,2,3,4,1,4,3,2,1 on a computerized pressure mat while timed using the Prokinetic Zeno mat for 2 trials every 6-8 weeks up to 7 sessions. Data Analysis: Statistical analysis using SPSS (vs. 26.0, IBM, Inc.) provided descriptive statistical analysis including correlation coefficients with repeated measures MANOVA for group differences at p = 0.05. Results: 44 participants (F/M = 9/35) contributed to 244 completed iFSST trials over 18 months. Timed trials averaged 8.79 +/- 2.02 sec., Backward Transitions (sq3 - sq4) and (sq2 – sq1) indicated a significantly different strategy between fallers & non-fallers (p=0.028) with decreased efficiency (COPe) scores (< 50%). Conclusions: Preliminary results indicate a significant deficit in backwards stepping transitions for PPD with an identified history of falls compared to PPD without falls. Clinical Relevance: Results suggest that multi-directional step performance using iFSST can yield early detection of fall risk in persons with degenerative motor disorders.
