Background: Impaired postural stability places individuals with Parkinson’s at an increased risk for falls. Given the high incidence of fall-related injuries within this population, ongoing assessment of postural stability is important. Objective: To evaluate the validity of the Nintendo Wii^® balance board as a measurement tool for the assessment of postural stability in individuals with Parkinson’s. Subjects: Twenty individuals with Parkinson’s participated. Intervention: Subjects completed testing on two balance tasks with eyes open and closed on a Wii^® balance board and biomechanical force platform. Main Measures: Bland–Altman plots and a two-way, random-effects, single measure intraclass correlation coefficient model were used to assess concurrent validity of centre-of-pressure data. Results: Concurrent validity was demonstrated to be excellent across balance tasks (intraclass correlation coefficients = 0.96, 0.98, 0.92, 0.94). Conclusions: This study suggests that the Wii^® balance board is a valid tool for the quantification of postural stability among individuals with Parkinson’s.

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 excursion as compared with that of healthy age-matched controls. This suggests that participants with Parkinson's disease may be overconstraining their postural adjustments in order to focus attention on the cognitive tasks without losing their balance. Ironically, this overconstraint may place the participant at greater risk for a fall.

Background. Internationally, the World Federation of Occupational Therapists has established a minimum of 1,000 hours as the fieldwork standard.Purpose. To examine student development in fieldwork across placements to determine if students achieve entry-level competence after completion of 1,000 hours of fieldwork.Methods. Archival data (N=400) from six occupational therapy programs were analyzed to examine the acquisition of fieldwork competency over time as measured by the Competency Based Fieldwork Evaluation Scale.Findings. Competency scores increased with each fieldwork placement, the majority of students achieved entry-level scores upon completion of their final fieldwork placement. While, on average, some competency scores exceeded entry level by 1,000 hours, Practice Knowledge, Clinical Reasoning, and Facilitating Change fell just short.Implications. The identification of a plan for addressing the lower ratings in these three competencies should be considered.

Up to 40% of all individuals with Parkinson’s disease (PD) are estimated to experience anxiety that interferes with daily functioning. This article describes research regarding the presentation of anxiety in PD and the influence anxiety has on participation in this population. A scoping review identified 1,635 articles, of which 49 met the inclusion criteria. This review identified that anxiety in PD is often associated with a range of clinical correlates related to demographic and clinical characteristics (age, gender, disease stage, duration, progression), motor symptoms (tremor, bradykinesia, dystonia, freezing of gait, symptom severity), treatment-related complications (on/off fluctuations, on with dyskinesia, unpredictable off), and non-motor symptoms (sleep abnormalities, fatigue, cognitive impairment, depression). These findings can be used to increase clinicians’ awareness toward the specific clinical correlates linked to anxiety in PD so that mental health concerns can be detected and addressed more readily in practice.

Although it is accepted that individuals with Parkinson’s disease must navigate challenges such as receiving their diagnosis and changing daily occupations, little is known about how they navigate. The purpose of this study is to deepen the current understanding of the experience of living with Parkinson’s disease and its implications for occupation through a narrative visual methodology (photo-elicitation). Six individuals with Parkinson’s disease were asked to take photographs and share verbal narrative accounts to illustrate their experience of living with Parkinson’s disease. Results highlight the interrelationship between occupation and identity, as many of the participants’ stories were interpreted as foregrounding the negotiation of occupation, and how such negotiation shaped their sense of identity. Overall, three major themes were identified: (1) Framing the meaning of Parkinson’s disease (accepting the disease as part of who they were); (2) Negotiating engagement in occupation (ongoing deliberation over whether to continue engaging in certain aspects of life as Parkinson’s disease progressed); and (3) Being ready to accept changes that impact personal or social identity (readiness to accept help and to identify as someone with Parkinson’s disease). Attending to insights regarding the lived experience of Parkinson’s disease will enhance quality of care through informing an enriched client-centered, occupation-based approach.
