Abstract: BACKGROUND:To date little is known about factors affecting walking rehabilitation in Parkinson’s disease (PD) patients. OBJECTIVE:This prospective observational cohort study evaluated the walking distance covered in 6 minutes (6 MWD) before and after conventional rehabilitation and verified which among PD motor disorders was the most important determinant of walking distance in PD patients undergoing rehabilitation. METHODS:Data were collected from 55 PD patients, performing a conventional outpatient motor rehabilitation program. The 6MWD at the end of rehabilitation and gain in 6MWD were the outcome measures. The Unified Parkinson’s Disease Rating Scale, Hoehn and Yahr scale, Nine Hole Peg Test, Grip and Pinch test, ROM wrist motility, and Berg Balance Scale (BBS) were used to assess PD patients at admission and were considered as dependent variables. Backward multiple regression analyses identified the determinants of 6MWD outcomes. RESULTS:The 6MWD was 246.58±115 meters at admission and 286.90±116 at the end of rehabilitation. At end of rehabilitation, the 6MWD was 42.32±47 meters greater than admission (p < 0.001), corresponding to an increase of +17.16%. At the end of rehabilitation, the 6MWD was significantly longer in PD patients with stages 1–3 of the Hoehn and Yahr scale. Berg Balance Scale (β= 0.47, p < 0.001) and right Grip and Pinch at admission (β= 0.36, p = 0.001) were the only determinants of final 6MWD. The R2 value of the model was 0.47 (R2 adjusted 0.45). No variable was a determinant of gain in 6MWD. CONCLUSIONS:The study indicates that balance and generalized muscle strength are important determinants of walking rehabilitation in PD patients, in whom it is essential to maintain high levels of balance and muscle strength for a time as long as possible. These findings suggest planning more intensive rehabilitation treatments in PD patients with low levels of balance and muscle strength.
