Abstract:
Objective To explore the effects of extrinsic and intrinsic recognition loading on gait in patients with Parkinson disease.Methods Eight patients with Parkinson disease and six control subjects were instrutted to walk with extrinsic and intrinsic recognition loading respectively.The gait parameters in two conditions were measured with three-dimension motion analysis equipment.FAB scale and Stroop Test were used as the evaluation of executive function.Results The velocity(cm/s),the cadence(step/min),single support and swing phase(%)in the audition stimulates condition in the patients group((113.4±14.32)step/min,(78.90±16.35)cm/s,(40.50±2.58)%,(40.50±2.58)%)were significantly better than those in the calculation condition(respectively(91.27±15.54)step/min,(63.79±21.49)cm/s,(37.95±2.61)%,(37.95±2.61)%).In the calculation condition,the coefficients of variability in stride length,swing and sinfle support phase were significantly higher in the patient group(respectively(6.69±3.99),(8.56±5.69),(8.56±5.69))than in thecontrol group(respectively(3.23±1.34),(5.02±2.54),(5.02±2.54));in the audition condition,except that,the coefficients of variability in step length and velocity also were significantly higher in the patient group(respeetively(11.92±5.86),(6.89±4.98))than the control group(respectively(7.35±3.32),(2.5±1.53)).In the patients group,the score of FAB(15.63±1.51)was lower and error rates of Stroop test(0.087±0.056)was higher than those in the control group(respectively(17.67±0.52),(0.027±0.03))significantly.The error rate of stroop-3 was significantly negative correlated with the gait variables of patient group in the calculation condition.Conclusion The extrinsic audition stimulates has lower effect on the gait of patients of Parkinson's disease than the intrinsic recognition loading.
