Does the impaired postural control in Parkinson's disease affect the habituation to non-sequential external perturbation trials?
2021, Clinical BiomechanicsCitation Excerpt :People with PD present a modest impairment on postural control in situations with external perturbation compared to CG. The greater range of CoP in the first trial and the greater MG/TA co-activation, greater recovery time, and lower iEMG of BF in the unpredictable translation of the support base in people with PD may reflect the central nervous system inability in controlling the muscle activity and in coordinating the muscles in people with PD vs. CG (Bloem, 1992; Dimitrova et al., 2004b; Horak et al., 1992). Indeed, this inadequate muscle control might be associated with the typical rigidity and bradykinesia symptoms in PD, which could impair the balance maintenance, mainly in more challenging situations, such as after external perturbation (Horak et al., 2005; Peterson and Horak, 2016).

2019, Human Movement ScienceCitation Excerpt :These different responses can be explained by the CNS inflexibility to control the muscles activities adequately and the passive stiffness capacity. Reactive postural adjustments have been associated with motor impairments characteristic of PD (Bloem, 1992; Horak et al., 2005, 1992). The motor symptoms, especially bradykinesia and muscle stiffness (Bloem, 1992; Horak et al., 1992; Peterson, Dijkstra, & Horak, 2016) which are more evident in the PIGD subtype, are reported to contribute to difficulties in postural control.
Dopaminergic polymorphisms associated with medication responsiveness of gait in Parkinson's disease
2018, Parkinsonism and Related DisordersCitation Excerpt :This effect parallels our previous finding that a single-blind, placebo control l-DOPA administration improves motor sequence learning in patients who are DRD2 T allele carriers [5]. The current study extends our findings to gait function, which can cause significant disability in Parkinson's disease patients [1,24]. Gait tends to be less responsive to both dopaminergic treatment and deep brain stimulation in Parkinson's disease [2,4].
