The association between sleep deficits and sedentary behavior in people with mild Parkinson disease.

Purpose: Sleep deficits are a common nonmotor symptom of Parkinson disease (PD). People with mild PD also achieve less physical activity (PA) than healthy older adults (HOA), but the relationship between sleep and PA in PD is unclear. This study examined associations between sleep and PA in participants with PD and HOA.Materials and Methods: Secondary analysis of a prospective observational study. Participants wore a commercially available activity monitor for two weeks. Wilcoxon Rank-Sum tests compared nighttime sleep, wakenings after sleep onset, number of wakenings, naps, step count, and PA intensity between PD and HOA groups. Age-adjusted regression models calculated associations between nighttime sleep and PA.Results: Per day, participants with PD slept 75 fewer minutes (p < 0.01), took 5,792 fewer steps (p < 0.001), achieved less PA at all intensities, and had 32% more sedentary time (p < 0.001) compared to HOA. Thirty minutes more sleep was associated with 26 fewer sedentary minutes for HOA (p = 0.01) and 25 fewer sedentary minutes for the PD group (p < 0.001).Conclusions: Sleep and PA are reduced in mild PD compared to HOA. Both groups demonstrated similar associations between reduced sleep and increased sedentary behavior. Results may encourage providers to screen for sleep deficits when promoting PA.IMPLICATIONS FOR REHABILITATIONThe use of a wrist-worn commercial activity and sleep monitor was well tolerated by both healthy older adults and people with mild Parkinson Disease in this study.People with mild Parkinson Disease slept less and were less active than a group of healthy older adults.Less sleep was associated with more sedentary behavior in both groups.The relationship between poor sleep and sedentary behavior in mild Parkinson Disease suggests that rehabilitation interventions may be optimized by targeting both physical activity and sleep deficits.

Compared to Individuals with Mild to Moderate Obstructive Sleep Apnea (OSA), Individuals with Severe OSA Had Higher BMI and Respiratory-Disturbance Scores.

OBJECTIVE: Individuals with obstructive sleep apnea (OSA) are at increased risk to suffer from further somatic and sleep-related complaints. To assess OSA, demographic, anthropometric, and subjective/objective sleep parameters are taken into consideration, but often separately. Here, we entered demographic, anthropometric, subjective, and objective sleep- and breathing-related dimensions in one model. METHODS: We reviewed the demographic, anthropometric, subjective and objective sleep- and breathing-related data, and polysomnographic records of 251 individuals with diagnosed OSA. OSA was considered as a continuous and as categorical variable (mild, moderate, and severe OSA). A series of correlational computations, X2-tests, F-tests, and a multiple regression model were performed to investigate which demographic, anthropometric, and subjective and objective sleep dimensions were associated with and predicted dimensions of OSA. RESULTS: Higher apnea/hypopnea index (AHI) scores were associated with higher BMI, higher daytime sleepiness, a higher respiratory disturbance index, and higher snoring. Compared to individuals with mild to moderate OSA, individuals with severe OSA had a higher BMI, a higher respiratory disturbance index (RDI) and a higher snoring index, while subjective sleep quality and daytime sleepiness did not differ. Results from the multiple regression analysis showed that an objectively shorter sleep duration, more N2 sleep, and a higher RDI predicted AHI scores. CONCLUSION: The pattern of results suggests that blending demographic, anthropometric, and subjective/objective sleep- and breathing-related data enabled more effective discrimination of individuals at higher risk for OSA. The results are of practical and clinical importance: demographic, anthropometric, and breathing-related issues derived from self-rating scales provide a quick and reliable identification of individuals at risk of OSA; objective assessments provide further certainty and reliability.

Impact of secondary health conditions on social role participation for a long-term physical disability cohort.

For people living with long-term physical disability (LTPD) social participation may involve managing physical impairments and secondary health conditions (SHCs) that are not due to the pathophysiology of the LTPD diagnosis itself. Prior research found a negative relationship between SHCs and participation in social roles in people with spinal cord injury (SCI). We expand on this research by investigating the influence of SHCs on participation in social roles for people with one of four LTPDs, controlling for co-variates. We (1) evaluated the associations between SHCs and participation in social roles; and (2) determined whether SHCs on individuals' ability to participate in social roles varies by type of diagnosis in those aging with either SCI, muscular sclerosis, muscular dystrophy, or post-polio syndrome. Cross-sectional, secondary data analysis from a return-by-mail survey. N = 1,573. Data were analyzed with multiple linear regressions (hypothesis 1), and then three moderated regressions (hypothesis 2). After controlling for demographics, SHCs were associated with lower ability to participate in social roles and accounted for 48% of the variance (all p's <.001). The relationship between depression and social role participation was moderated by diagnosis, such that depression was more negatively associated with social participation among individuals with SCI (p = .020). Thus, SHC negatively impact participation in social roles.

Occupational Therapy and Primary Care: Updates and Trends.

As our health care system continues to change, so do the opportunities for occupational therapy. This article provides an update to a 2012 Health Policy Perspectives on this topic. We identify new initiatives and opportunities in primary care, explore common challenges to integrating occupational therapy in primary care environments, and highlight international works that can support our efforts. We conclude by discussing next steps for occupational therapy practitioners in order to continue to progress our efforts in primary care.

Expanding the Implementation of the Americans With Disabilities Act for Populations With Intellectual and Developmental Disabilities: The Role of Organization-Level Occupational Therapy Consultation.

The Americans With Disabilities Act (ADA) provides standards and guidance for accessibility and accommodations that remove barriers to facilitate community social participation for individuals with disabilities. However, ADA implementation does not yet fully address the diverse access needs of people with intellectual and developmental disabilities (IDD), who continue to face barriers to community social participation. This article explores the potential for occupational therapy practitioners to provide organization-level consultation as a means of maximizing community social participation among people with IDD. Case examples of occupational therapy practitioners working with community organizations are presented to illustrate organization-level consultation that addresses access needs across diverse community contexts. The relevance of supporting community social participation within the context of health equity is discussed, and key next steps, including developing population-based outcome measures, addressing reimbursement considerations, and developing best practices for organization-level consultation, are outlined.

Qualitative Experience of Sleep in Individuals With Spinal Cord Injury.

Poor sleep contributes to adverse health outcomes making it important to understand sleep in medically vulnerable populations, including those with spinal cord injury (SCI). However, little attention has been paid to circumstances specific to SCI that may negatively affect sleep, or to consequences of poor sleep in this population. The objective of this study was to examine the experience of sleep among individuals with SCI. Secondary analysis using thematic coding of qualitative data from an ethnographic study of community-dwelling adults with SCI was conducted. Sleep-related data were found in transcripts for 90% of the sample. Participants described diminished sleep duration and irregular sleep patterns. Several factors contributing to poor sleep were identified, including SCI-related circumstances and sleep environment. Participants also discussed how poor sleep affected occupational engagement. This study highlights the extent of sleep disturbance experienced after SCI and the subsequent impact on occupational performance, and provides direction for clinical practice.

Occupational Therapy and Management of Multiple Chronic Conditions in the Context of Health Care Reform.

One in four individuals living in the United States has multiple chronic conditions (MCCs), and the already high prevalence of MCCs continues to grow. This population has high rates of health care utilization yet poor outcomes, leading to elevated concerns about fragmented, low-quality care provided within the current health care system. Several national initiatives endeavor to improve care for the population with MCCs, and occupational therapy is uniquely positioned to contribute to these efforts for more efficient, effective, client-centered management of care. By integrating findings from the literature with current policy and practice, we aim to highlight the potential role for occupational therapy in managing MCCs within the evolving health care system.

Comparison of Sleep Problems in Individuals with Spinal Cord Injury and Multiple Sclerosis.

STUDY OBJECTIVES: Sleep problems are common in spinal cord injury (SCI) and multiple sclerosis (MS). However, the degree to which sleep problems differ between these distinct clinical populations has not been evaluated. In this study, we examined self-reported sleep problems in individuals with SCI and those with MS, and compared these clinical groups on the Medical Outcomes Study Sleep Scale (MOS-SS). METHODS: Participants were 1,677 individuals (SCI = 581; MS = 1,096) enrolled in longitudinal study of self-reported health outcomes in SCI and MS. Univariate and multivariate analysis of covariance examined group differences on global sleep problems and domain-specific subscales of the MOS-SS. RESULTS: Individuals with SCI reported an average of 30 fewer min of sleep per night (Sleep Quantity subscale) and significantly greater difficulty initiating and maintaining sleep (Sleep Disturbance subscale) compared to individuals with MS. However, groups did not differ on global sleep problems (Sleep Problems Index 9). CONCLUSIONS: Although global sleep problems are more common in SCI and MS than in the general population, these groups exhibit differing sleep problem profiles, and thus may require unique treatment approaches to address the specific domains of sleep affected. For individuals with SCI, an additional focus on increasing sleep quantity and reducing sleep disruptions may be warranted.

The role of habit in recurrent pressure ulcers following spinal cord injury.

BACKGROUND: Despite the existence of numerous prevention strategies, pressure ulcers remain highly prevalent in those with spinal cord injury (SCI). The concept of habit, broadly defined, may help understand the persistence of this problem and offer strategies for its mitigation by occupational therapy. AIM: The aim of this paper is to describe the relationship between habits established prior to sustaining an SCI and post-injury habits that impacted on pressure ulcer risk. METHODS: Secondary analysis of qualitative data collected during an ethnographic study of community-dwelling adults with SCI. RESULTS: Participants' habits appeared to substantially affect their risk of developing pressure ulcers. Habits established before incurring the SCI either facilitated or hindered the acquisition of new habits intended to prevent pressure ulcers. CONCLUSIONS: An understanding of the individual's pre-existing habits may be important when designing a rehabilitation programme intended to minimize risk of pressure ulcer development following SCI. Habit-change strategies could be used to supplement education in pressure ulcer prevention techniques. SIGNIFICANCE: Occupational therapists have a longstanding interest in habit. A more comprehensive understanding of this concept may provide important insights into the persistence and management of pressure ulcers following SCI.

Comparison of self-report sleep measures for individuals with multiple sclerosis and spinal cord injury.

OBJECTIVE: To investigate self-report measures of sleep disturbances and sleep-related impairments in samples of individuals with multiple sclerosis (MS) or spinal cord injury (SCI). DESIGN: Cross-sectional survey. SETTING: Community based. PARTICIPANTS: Adults (age ≥18y) (N=700) with either MS (n=461) or SCI (n=239) who were enrolled in a longitudinal survey of self-reported health outcomes and who completed self-report sleep measures at 1 time point. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Medical Outcomes Study Sleep Scale (MOS-S), Patient Reported Outcomes Measurement Information System (PROMIS) sleep disturbance short form, and PROMIS sleep-related impairments short form. RESULTS: Mean scores on the MOS-S sleep index II were significantly worse for both the MS and SCI samples than those of previously reported samples representative of the U.S. general population (P<.0001 for each group). The PROMIS sleep disturbance short form and PROMIS sleep-related impairments short form scores of the MS sample were also significantly different from those reported for the calibration cohort (P<.0001 on each scale). However, although the scores of the SCI sample were significantly different from those of the comparison cohort for the PROMIS sleep-related impairments short form (P=.045), the differences on the PROMIS sleep disturbance short form were not significant (P=.069). CONCLUSIONS: Although the MOS-S scores for the MS and SCI cohorts clearly indicated significantly high levels of sleep-related problems and were consistent with existing literature, the more ambiguous findings from the PROMIS sleep disturbance short form and PROMIS sleep-related impairments short form suggest that not enough is currently known about how these instruments function when applied to those with chronic neurologic dysfunction.

Association of sleep and co-occurring psychological conditions at 1 year after traumatic brain injury.

OBJECTIVES: To compare individuals' sleep 1 year after traumatic brain injury (TBI) with that of a healthy comparison group, and examine the relationship between sleep, co-occurring conditions, and functional status in those with TBI. DESIGN: Longitudinal assessment of a prospectively studied sample of individuals with moderate to severe TBI. Assessment of sleep occurred at 1 year after TBI. SETTING: Inpatient acute rehabilitation for TBI and community follow-up at 1 year postinjury. PARTICIPANTS: Individuals with TBI (N=174) were recruited from consecutive admissions to an inpatient rehabilitation unit and enrolled into the TBI Model Systems study. Participant mean age was 38, and mean Glasgow Coma Scale score on admission was 9.3. Seventy-eight percent of the sample were men. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Sleep was assessed with the Pittsburgh Sleep Quality Index (PSQI). Depression, anxiety, and pain were measured with the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7 Scale, and an analog pain rating scale, respectively. RESULTS: Participants with TBI reported significantly greater sleep difficulties than the healthy comparison group. Forty-four percent of participants with TBI reported significant sleep problems (PSQI>5). Participants with 1 or more co-occurring conditions (depression, pain, or anxiety) had significantly worse sleep than those without such a condition. The highest level of sleep problems was reported by participants with multiple co-occurring conditions. Sleep problems were also associated with poor functional status. CONCLUSIONS: Sleep difficulties are a frequent problem at 1 year after TBI, and often co-occur with depression, anxiety, and pain. Assessment and treatment of sleep difficulties should be included in clinical practice. Future research on the potential causal relationship among co-occurring conditions may assist in additional intervention planning.
