Introduction: Parkinson’s disease (PD) is a heterogeneous neurodegenerative disorder. Atypical posture and mobility of individuals with PD (IwPD) increase the risk of falls and limits the capabilities of daily activities. Reduced range of motion in IwPD is attributed to rigidity and may be hindering trunk coordination, and consequently contribute to gait dysfunction (i.e., decreased step and stride length), turning difficulties, and poor posture. In a neurotypical gait pattern, there is a progressive transition mainly from in-phase to anti-phase coordination, in the axial plane, as gait speed increases. An in-phase pattern is more evident in lwPD; resulting in the trunk and pelvis to display synchronous axial rotations in the same direction. Furthermore, IwPD have increased difficulty performing more than one task simultaneously, possibly due to restricted central processing. It’s hypothesized that trunk-pelvis coordination (TPC) will be aggravated during dual-task (DT) activities, and greater DT inference (DTI) will occur during motor-motor DT (MMDT) than cognitive-motor DT (CMDT). Aim: The primary aim of this study was to establish if DT activities, in contrast to single-task (ST) conditions, affect TPC during walking in individuals with mild to moderate PD compared to apparently healthy age- and sex-matched individuals (Control group). The secondary aims were to compare two DT paradigms (namely MMDT or CMDT), and to determine which condition resulted in the most interference for TPC, gait variables and other coordination indices, during walking in IwPD compared to the control group. Methods: This was a cross-sectional within-group and between-group quasi-experimental study design that made use of the convenience sampling technique. Participants were asked to randomly perform a ST (i.e., 2 Minute Walk) and DT activities (i.e., CMDT by serial three subtraction, and MMDT by carrying a tray with two glasses). Results: Twenty-two IwPD (age 72.50 ± 4.35 years; 1.82 ± 0.66 Hoehn & Yahr scale) and 22 healthy age- and sex-matched Control group (age 72.77 ± 4.30 years) were tested under ST, MMDT and CMDT conditions. Significant interaction effects were found for gait speed, gait variability, gait speed variability and TPC variation (p < 0.01), with post-hoc results indicating that CMDT cause a great deterioration in gait in both groups. Results of the DTI show significant interaction effects for gait speed (p < 0.01), stride time (p = 0.02), gait variability (p =0.02), and gait speed variability (p < 0.01). Great DTI was observed in MMDT than CMDT for TPC in the PD group and Control group. Conclusion: The findings suggest that DT gait performance is influenced by MMDT and CMDT in IwPD. Dual-task interference on gait parameters were significant in both DT conditions in the PD and Control group. The findings may contribute to the way healthcare professionals treat IwPD, by modifying expectations and monitoring the cognitive and/or motor demands placed on IwPD both in everyday life and during rehabilitation may improve quality of life and independence.
