Evidence-based practice requires that clinicians interpret the best research evidence in the context of their clinical experience, while at the same time considering client knowledge and experiences. Although clinicians are becoming increasingly skilled at the evaluation of research evidence, the evidence-based practice process often neglects client values and self-identified health issues. Ignoring these key aspects of client-centered practice may lead to interventions that fail to target the implications of a client’s disease that are important to occupational participation and quality of life (QOL). A focus on client-centeredness is particularly important in progressive neurodegenerative disorders, such as Parkinson’s disease, where there …
The Effects Of Word Length, Articulation, Oral-Motor Movement, And Lexicality On Gait: A Pilot Study, K. Davie, Janis Cardy, J. Holmes, M. Gagnon, A. Hyde, M. Jenkins, Andrew Johnson
The Effects Of Word Length, Articulation, Oral-Motor Movement, And Lexicality On Gait: A Pilot Study, K. Davie, Janis Cardy, J. Holmes, M. Gagnon, A. Hyde, M. Jenkins, Andrew Johnson
Andrew M. Johnson
Previous research has suggested that articulatory demands are important predictors of the impact of dual-task interference on spatial-temporal parameters of gait. In this study, we evaluated the effects of word length, oral-motor movement, articulation, and lexicality, within a verbal task, on a continuous gait task. Fifteen healthy young women participated in a study in which two word lengths (monosyllabic and bisyllabic) were crossed with four levels of secondary task complexity (no dual-task, non-speech movement, spoken non-word, and spoken word). Spatial and temporal parameters of gait were measured using a 23' instrumented carpet. Results indicated a significant multivariate main effect for …

Balance problems and falls are a common concern among individuals with Parkinson's disease (PD). Falls frequently occur during daily activities such as reaching into cupboards in the kitchen or bathroom. This study compared the correlation among two standard postural stability tests - the postural stability score on the Unified Parkinson's Disease Rating Scale (UPDRS) and the Functional Reach Test (FRT) - and ecologically valid reaching tasks that correspond to reaching at different cupboard heights among 20 individuals with PD and 20 age-matched controls. Both the FRT and the UPDRS postural stability tests are quick measures that can be performed during …

Although dual-task interference has previously been demonstrated to have a significant effect on postural control among individuals with Parkinson's disease, the impact of speech complexity on postural control has not been demonstrated using quantitative biomechanical measures. The postural stability of twelve participants with idiopathic Parkinson's disease and twelve healthy age-matched controls was evaluated under three conditions: (1) without a secondary task, (2) performing a rote repetition task and (3) generating a monologue. Results suggested a significant effect of cognitive load on biomechanical parameters of postural stability. Although both groups increased their postural excursion, individuals with Parkinson's disease demonstrated significantly reduced …

Although previous research has attempted to identify the needs of caregivers for individuals with Parkinson's disease (PD), most has focused on the demands associated with the physical needs of the patient, and not on "mental burden." This study used the repertory grid method to capture the full range of caregivers' subjective experience, quantify their perceptions, and to acquire information that might be useful in directing remediation attempts. Within this sample, caregivers reported far greater burden from "mental stress" (e.g., worrying about individual's safety) than from "physical stress" (e.g., lifting individual into bed). Specifically, caregivers were primarily concerned about spousal safety, …

Parkinson's disease is a chronic neurological disorder that results in gait and posture impairment. There is increasing evidence that these motor impairments may be partially due to deficits within the sensory system. In this study, the effects of a facilitatory insole that provides increased plantar sensory stimulation, was evaluated during gait, in a group of individuals with Parkinson's disease in comparison with healthy age-matched controls. Spatial-temporal parameters of gait were evaluated using an instrumented carpet, and muscle activation patterns were evaluated using surface EMG. All participants were tested with both a facilitatory (ribbed) insole and a conventional (flat) insole while …

The ability to execute and maintain gait while performing simultaneous cognitive, verbal, or motor tasks ('dual-tasking') is beneficial in many ways. It is well-documented, however, that dual-tasking can result in cognitive or motoric interference that results in diminished gait performance, and impaired secondary task performance. When manipulating cognitive load, it is common to have participants respond verbally to stimuli. While this is an ecologically valid way to measure the effects of cognitive load on gait, it ignores the additional demands inherent in the verbal aspect of the task. In the present study, we manipulated complexity and articulation within a single …

Although medication therapy is generally effective in the clinical management of Parkinson's disease (PD), additional improvement of some gross motor symptoms may be achieved through the use of nonpharmacological treatments, such as physical therapy and exercise rehabilitation. Despite the fact that PD is a neurological disorder, successful rehabilitation has been demonstrated with treatments that combine cognitive and physical approaches. While the exact mechanism through which these therapies obtain successful outcomes is still largely unknown, it is worthwhile to explore these adjunctive approaches to treating the motor output symptoms of PD.

From Perception To Execution In Parkinson’S Disease, Andrew Johnson, Quincy Almeida

Parkinson’s disease (PD) is a progressive neurodegenerative disorder that affects one’s ability to control voluntary movements. Typically, PD is considered a disease of motor output, without considering neuropsychological variables that might contribute to the impairment of movement. The goal of this chapter is to investigate issues of motor control, in addition to the observable motor symptoms found in PD from a perceptual and cognitive perspective. To this end, we divide movement into three components: perception, initiation, and execution. Perception is required initially, and throughout movement, and is generally used to define characteristics of a movement goal. Thus, in the earliest …

Sublingual Atropine For Sialorrhea Secondary To Parkinsonism: A Pilot Study, H. Hyson, Andrew Johnson, Mandar Jog

Sialorrhea is a relatively common symptom in idiopathic Parkinson's disease and related conditions for which most of the accepted treatments are either highly invasive or may cause substantial systemic side effects. This study describes an open-label pilot study of sublingual atropine drops for the treatment of sialorrhea in 7 patients (6 with Parkinson's disease, 1 with progressive supranuclear palsy). Participants demonstrated statistically significant declines in saliva production, both objectively and subjectively. Self-reported drooling severity showed a significant decline between baseline and 180 minutes, t(6) = 3.240 P < 0.025 (eta(2) = 0.636), and between baseline and 1 week, t(6) = 4.583 …
