INTRODUCTION: En bloc turning highlights a lack of rotational intersegmental coordination, which commonly impacts turning ability in people with Parkinson's disease (PD). Whilst this turning deficit responds fairly well to medical treatment, it may be further mitigated by performing specific exercise training. Thus, the present study aimed to examine the effects of a 4-week exercise program, which focused on task-specific movements (TSM program) on turning ability and clinical outcomes in people with PD. METHODS: Twenty-two adults (67 +/- 6 years) with early-to-mid-stage idiopathic PD were randomly assigned to an experimental group (EG; n = 11) or a control group (CG; n = 11). The exercise group (EG) group received a 60-min per session TSM program for 4 weeks (a total of 15 sessions), while the CG group performed their routine rehabilitation program (a total of 12 sessions). Inertial measurement units were used to measure turning kinematics including; onset latency of body segments and stepping characteristics. Clinical outcomes included the Unified Parkinson's Disease Rating Scale (UPDRS), functional reach test (FRT), and fall efficacy scale international (FES-I). Assessments were conducted at baseline and after 4 weeks. RESULTS: In the EG, turning kinematics, UPDRS scores, FRT, and FES-I scale, were improved at the end of the 4-week program compared with the CG (all p < 0.05). IMPACT STATEMENT: A 4-week TSM program could be a promising alternative rehabilitation program for improving "en bloc" turns and clinical outcomes in PD patients.
