- ItemObstacle crossing among people with Parkinson disease is influenced by concurrent music(U.S. Department of Veteran's Affairs, 2010) Brown, Lesley; de Bruin Nutley, Natalie; Doan, Jon B.; Suchowersky, Oksana; Hu, BinMultitasking situations exacerbate gait impairments and increase the risk of falling among people with Parkinson disease (PD). This study compared obstacle negotiation among 10 subjects with PD and 10 nonparkinsonian control (CTRL) subjects in two test conditions differentiated by the presence of music played through a personal music player. Subjects walked the length of a 10 m walkway at a self-selected pace, crossing a 0.15 m obstacle placed at the midpoint of the walkway. The results indicated that subjects with PD crossed the obstacle slower than CTRL subjects and that concurrent music differentially altered obstacle crossing behaviors for the CTRL subjects and subjects with PD. Subjects with PD further decreased obstacle-crossing velocities and maintained spatial parameters in the music condition. In contrast, CTRL subjects maintained all spatiotemporal parameters of obstacle crossing with music. The alterations to crossing behaviors observed among the subjects with PD support our previous suggestion that listening to music while walking may be an attentionally demanding task.
- ItemWalking with music is a safe and viable tool for gait training in Parkinson's disease: the effect of a 13-week feasibility study on single and dual task walking(Hindawi Publishing Corporation, 2010) de Bruin Nutley, Natalie; Doan, Jon B.; Turnbull, George; Suchowersky, Oksana; Bonfield, Stephan; Hu, Bin; Brown, LesleyThis study explored the viability and efficacy of integrating cadence-matched, salientmusic into a walking intervention for patients with Parkinson’s disease (PD). Twenty-two people with PD were randomised to a control (CTRL, n = 11) or experimental (MUSIC, n = 11) group. MUSIC subjects walked with an individualised music playlist three times a week for the intervention period. Playlists were designed to meet subject’s musical preferences. In addition, the tempo of the music closely matched (±10– 15 bpm) the subject’s preferred cadence. CTRL subjects continued with their regular activities during the intervention. The effects of training accompanied by “walking songs” were evaluated using objective measures of gait score. The MUSIC group improved gait velocity, stride time, cadence, and motor symptom severity following the intervention. This is the first study to demonstrate that music listening can be safely implemented amongst PD patients during home exercise.
- ItemPerception of safe horizontal reaching distance changes with repetitive occupational loading in novice lifters(Elsevier, 2015) McCubbing, Dustin C.; Shan, Gongbing; Gonzalez, Claudia L. R.; Awosoga, Olu A.; Doan, Jon B.Safe work behaviours rely on accurate perceptions of injury risks, and workers who have a misperception of risk can be injured. Despite the importance of perception-action coupling, little is known about modification of those perceptions with changing physical or cognitive STATE. It is hypothesized that changing values for perceived affordances could evidence these modifications. A better understanding of how worker characteristics (e.g., level of fatigue) affect perceptions of affordance and their corresponding behaviours, may help when developing strategies for ergonomic best practices, particularly in manual material handling (MMH) activities. The aim of this study was to compare safe perceptions of affordance from workers that completed repetitive STATE loading. Seventy-five novice MMH workers (23 male; mean age = 21.43, SD = 3.24) made perceived affordances of their safest horizontal reaching distance (acceptable limit) to complete a model task. STATE loading consisted of physical or cognitive fatigue or a control. The levels of fatigue were assessed at five-minute intervals using Ratings of Perceived Exertion (RPE) values and Multi-Fatigue Inventory (MFI) values, respectively. A significant main effect of TIME indicated a decrease of perceived safest reaching distance observed from baseline through subsequent measurements (p<.001). The magnitude of these changes did not differ significantly between groups, suggesting that general learning more than specific STATE loading may be a major contributor to modification of affordance perceptions. However, it remains important to consider TIME and STATE influences on perceptions for safe occupational handling. Novice workers’ initial perceptions of safe working affordance may put them at risk for soft tissue injury. Physical and cognitive loading similarly affect perceived safe affordances.
- ItemFunctional improvements associated with upper extremity motor stimulation in individuals with Parkinson's disease(Lippincott, Williams, & Wilkins, 2015) Bartoshyk, Patrick J.; De Bruin, Natalie; Brown, Lesley A.; Doan, Jon B.Background: While traditional neurotherapy promotes motor function in people living with Parkinson’s disease (PD), the benefits may be limited by compounding physical, cognitive, and attentional barriers. Since the nontraditional exercise of ice-skating is proving to positively influence motor function and postural control, the purpose of this study was to explore whether the addition of an upper body sensory-driven motor coordination task (stickhandling) would provide upper extremity neuromotor benefit among people with moderate PD. Methods: Seven non-PD control (CTRL) and 22 PD (14 ON-ICE, 8 OFF-ICE) participants completed three trials of a reaching-to-eat (fine motor) task and a button-push (gross motor) task, PRE-and POST-completion of two dynamic – either on- or off-ice – stickhandling tasks. Reaching-to-eat and button-push scores were compared between time periods (PRE, POST) and groups (CTRL, PD ON-ICE, PD OFF-ICE). Results: CTRL participants demonstrated higher scores when compared to the PD groups. Both PD groups demonstrated an improvement in reaching-to-eat and button-push scores immediately following the intervention. Conclusions: These findings suggest that sport-derived exercise programs may provide neuromotor benefit to people living with PD.
- ItemCaring for paid professional caregivers: investigating the health status of long-term care and assisted living facilities workers in Alberta(University of Lethbridge, 2020) Awosoga, Olu A.; Doan, Jon B.; Steinke, Claudia; Sajobi, Tolulope T.; Murphy, Sheli; Baerg, Scott; Bolarinwa, Remi; Nord, Christina; Varsanyi, Stephanie E.; Dosu, Benjamin; Lucchesi, AnnitaThis is a report on the health status of paid professional caregivers in long-term care (LTC) and Assisted Living (AL) Facilities that was carried out in Alberta Province between June 2017 and October 2019.
- ItemWell-being of professional older adults' caregivers in Alberta's assisted living and long-term care facilities: a cross-sectional study(Springer Nature, 2023) Awosoga, Olu A.; Odole, Adesola C.; Onyeso, Ogochukwu K.; Doan, Jon; Nord, Christina; Nwosu, Ifeoma B.; Steinke, Claudia; Ojo, Joshua O.; Ekediegwu, Ezinne C.; Murphy, SheliBackground For the care need of older adults, long-term care (LTC) and assisted living (AL) facilities are expanding in Alberta, but little is known about the caregivers’ well-being. The purpose of the study was to investigate the physical health conditions, mental and emotional health (MEH), health behaviour, stress levels, quality of life (QOL), and turnover and absenteeism (TAA) among professional caregivers in Alberta’s LTC and AL facilities. Methods This cross-sectional survey involved 933 conveniently selected caregivers working in Alberta’s LTC and AL facilities. Standardised questions were selected from the Canadian Community Health Survey, Patient Health Questionnaire-9, and Short Form-36 QOL survey revalidated and administered to the participants. The new questionnaire was used to assess the caregivers’ general health condition (GHC), physical health, health behaviour, stress level, QOL, and TAA. Data were analysed using descriptive statistics, Cronbach alpha, Pearson’s correlation, one-way analysis of variance, and multiple linear regression. Results Of 1385 surveys sent to 39 facilities, 933 valid responses were received (response rate = 67.4%). The majority of the caregivers were females (90.8%) who were ≥ 35 years (73.6%), worked between 20 to 40 h weekly (67.3%), and were satisfied with their GHC (68.1%). The Registered Nurses had better GHC (mean difference [MD] = 0.18, p = 0.004) and higher TAA than the Health Care Aides (MD = 0.24, p = 0.005). There were correlations between caregivers’ TAA and each of MEH (r = 0.398), QOL (r = 0.308), and stress (r = 0.251); p < 0.001. The most significant predictors of TAA were the propensity to quit a workplace or the profession, illness, job stress, and work-related injury, F (5, 551) = 76.62, p < 0.001, adjusted R2 = 0.998. Conclusion Reducing the caregivers’ job stressors such as work overload, inflexible schedule, and poor remuneration, and improving their quality of life, health behaviour, and mental, emotional, and physical health conditions may increase their job satisfaction and reduce turnover and absenteeism.
