This study aimed to investigate whether symmetric and asymmetric bimanual coordination is impaired in Parkinson's disease patients with freezing of gait (PD + FOG) and whether dual-task and drug phases may affect bimanual coordination in these patients. PD + FOG patients demonstrated exacerbated impairments of bimanual coordination while performing goal-directed bimanual tasks, especially in asymmetric tasks and under dual-task conditions, highlighting the importance of rehabilitation interventions for bimanual tasks with different cognitive loads in these patients.
Freezing of gait (FOG) is a debilitating symptom in patients with Parkinson's disease (PD), which may be associated with motor control impairments in tasks other than gait. This study aimed to examine whether symmetric and asymmetric bimanual coordination is impaired in PD with FOG (PD +FOG) patients and whether dual-task and drug phases may affect bimanual coordination in these patients. Twenty PD +FOG patients, 20 PD patients without FOG (PD -FOG) performed symmetric and asymmetric functional bimanual tasks (reach to and pick up a box and open a drawer to press a pushbutton inside it, respectively) under single-task and dual-task conditions. PD patients were evaluated during on- and off-drug phases. Kinematic and coordination measures were calculated for each task. PD +FOG patients demonstrated exacerbated impairments of bimanual coordination while performing goal-directed bimanual tasks, which was more evident in the asymmetric bimanual task and under dual-task conditions, highlighting the need for rehabilitation interventions for bimanual tasks that include different cognitive loads in these patients. Interestingly, 25% and 5% of participants in the PD +FOG and -FOG groups developed upper limb freezing 2 years later, respectively. This study aimed to examine whether symmetric and asymmetric bimanual coordination is impaired in Parkinson's disease with freezing of gait (PD +FOG) patients and whether dual-task and drug phases may affect bimanual coordination in these patients. PD +FOG patients demonstrated exacerbated impairment of bimanual coordination while performing goal-directed bimanual tasks, highlighting the need for rehabilitation interventions for bimanual tasks that include different cognitive loads in these patients.
