Session Title: Physical and Occupational Therapy
Session Time: 1:45pm-3:15pm
Location: Les Muses Terrace, Level 3
Objective: We verified the usefulness of an automatic gait and posture analyzer for estimation of rehabilitation using Honda Walking Assist (HWA).
Background: The abnormal posture is one of the unsolved issues in advanced Parkinson’s disease (PD) patients. Although postural sway is often larger when walking than when standing in PD patients, the evaluation of postural sway during walking is not easy.
Method: We studied the effect of rehabilitation using HWA in PD patients outside. Patients did rehabilitation using HWA for 30 min, 10 times / 3 months (3M) or 20 times / 6 months (6M). We evaluated 10 meter and 3 min of walking test without HWA, Berg Balance Scale, Functional Reach Test (FRT), UPDRS part III, MDS-UPDRS 3.11 (freezing of gait) and Freezing of Gait Questionnaire at the pre and post-intervention. We used Mobile Motion Visualizer (MMV-001, SYSTEM FRIEND INC.), which uses an infrared camera to analyze step length, step width, walking speed and postural sway without marker.
Results: Three patients (mean UPDRS part III 19.7) participated. Patient 1 (75 y. o. female, 11 years PD duration, HY3): The step length in 10 meter walking and the distance in 3 min walking increased from 52.0 cm to 66.0 cm (3M) and from 182.0 to 190.7 (3M) and 204 (6M) meter. MMV showed improvement of step length from 49 to 55 cm (3M), walking speed from 44 to 59 meter / min (3M) and anterior postural sway from 21.4 to 19.5 (3M) and 18.1 (6M) degree. Patient 2 (73 y. o. female, 18 years PD duration, HY3): FRT and the distance in 3 min walking increased from 23.5 to 26.5 cm and from 149.0 to 164.5 meter (3M). MMV showed improvement of walking speed from 43.5 to 44.5 (3M) and 46.0 (6M) meter / min and anterior postural sway from 15.6 to 14.5 degree (6M). Patient 3 (80 y. o. female, 12 years PD duration, HY2): The distance in 3 min walking increased from 133.3 to 157.0. MMV showed improvement of step length from 47.0 to 52.5 cm and anterior postural sway from 10.6 to 9.7 degree.
Conclusion: The rehabilitation using HWA increased the distance in 3 min walking and improved anterior postural sway in PD patients. MMV was useful to evaluate the improvement of gait and postural sway.
