RESUMO
OBJECTIVES: We examined the effects of a walking intervention in older adults residing in long-term care (LTC) homes on gait velocity (primary outcome), and stride length, cadence and heel-to-heel base of support (secondary outcomes) compared to those in an interpersonal interaction control group and a care-as-usual control group at 16-weeks post-intervention. METHODS: These previously unpublished gait data were collected as part of a larger prospective, randomized, three group study. One hundred and sixty-eight participants residing in 12 LTC homes were randomized into: a) a walking group (n=57) - 1:1 supervised, individualized, progressive, 30 minutes, five times a week walking program for 16 weeks; b) an interpersonal interaction group (n=55) - stationary 1:1 conversation time with research personnel; and, c) a care-as-usual control group (n=56). Gait was assessed at baseline and 16-weeks post-intervention using the GAITRite® computerized system. One-way Analysis of Covariance (ANCOVA), controlling for age, sex, cognitive status and baseline gait parameter (velocity, stride length, cadence, heel-to-heel base of support) was used to examine differences among groups for velocity, stride length, cadence, and heel-to-heel base of support at 16-weeks post-intervention. RESULTS: Ninety-one participants with available data were included in this analysis: walking group (n=31/57, mean age=82.77±6.75 years); interpersonal interaction group (n=31/55, mean age=82.74±9.27 years); care-as-usual control group (n=29/56, mean age=85.40±8.78 years). ANCOVA showed a significant difference in the mean gait velocity at 16-weeks post-intervention [F(2, 84) =6.99, p=0.0006); η2 (95%CI)=0.16 (0.02, 0.27)]. Post hoc comparisons using Sidak test showed that the estimated marginal mean (EMM) for velocity for the walking group [EMM (SE), 0.51m/s (0.03)] was significantly higher compared to the interpersonal interaction group [EMM (SE), 0.38m/s (0.03); t(83)=3.15, p=0.007] and the care-as-usual control group [EMM (SE), 0.38m/s (0.03)]; t(83)=3.32, p=0.004]. No significant difference was observed between groups for stride length, cadence or heel-to-heel base of support. CONCLUSION: LTC residents with limited physical functioning showed significant improvement in gait velocity but not in stride length, cadence or heel-to-heel base of support after a 16-week walking intervention.

BACKGROUND: The most common methods for measuring mobility in older adulthood include performance-based tests, such as the Timed-Up-and-Go and gait speed. While these measures have strong predictive validity for adverse outcomes, they are limited to assessing what older adults do in standardized settings, rather than what they do in their daily life. Life-space mobility, which is the ability to move within environments that expand from one's home to the greater community, has been proposed as a more comprehensive measure of mobility. The aim of this study was to determine the association between modifiable factors and life-space mobility in older adults enrolled in the Canadian Longitudinal Study on Aging (CLSA). METHODS: Life-space mobility was measured using the Life Space Index (LSI). Explanatory factors included physical, psychosocial and cognitive determinants, as well as pain, fatigue, driving status, nutrition, body mass index, smoking status, and vision. To estimate the association between the LSI and explanatory variables, univariate and multivariable ordinary least squares regression analyses were performed. RESULTS: All adults 65 years and older (n = 12,646) were included in the analysis. Fifty percent were women and the mean age was 73.0 (SD5.7). The mean LSI score was 80.5, indicating that, on average, the sample was able to move outside of their neighborhood independently. All explanatory variables were significantly associated with the LSI except for balance and memory. The top 3 variables that explained the most variation in the LSI were driving, social support and walking speed. CONCLUSION: To our knowledge, this was the first study to examine the association between life-space mobility and a comprehensive set of modifiable factors that were selected based on a theoretical framework and existing research evidence. This study had two important messages. First, driving, social support and walking speed emerged as the most significant correlates of life-space mobility in older adults. Second, life-space mobility is multifactorial and interventions that are pragmatic in their design and testing are needed that consider the complexity involved. A multi-disciplinary approach to examining life-space mobility in older adults is needed to optimize opportunities for healthy aging and develop strategies that support mobility in older adulthood.

This scoping review explores circumstances surrounding the decision about, and eventual experience of, transitioning older adults into alternative levels of housing (ALH), such as long-term care. This topic is examined from a family member perspective, given their exposure and involvement in the care of older adult relatives during this transitional period. The scoping review methodology is based on the framework of Arksey and O'Malley and subsequent recommendations from Levac, Colquhoun, and O'Brien. Approximately 470 articles were reviewed covering the period between 2000 and November 2014; 37 articles met inclusion criteria. A temporal organization of themes was used to describe the experiences of family members in the pretransition, active transition, and posttransition periods of moving older adult relatives into ALH. This paper highlights the transitional period as a time of crisis, with a lack of planning, support, and transparent discussion. This study identifies a need for future research on the potential benefits of family support groups, interim transitional housing options, different models of ALH, changing roles in the posttransition period, and the need for a comprehensive list of housing options for older adults. Results have the potential to inform policy/practice and improve the lives of older adults and their family.
RESUMO
BACKGROUND: The purpose of this study was to compare the differences across occupational groups related to their end-of-life care-specific educational needs and reported intensity of interprofessional collaboration in long-term care (LTC) homes. METHODS: A cross-sectional survey, based on two questionnaires, was administered at four LTC homes in Ontario, Canada using a modified Dilman's approach. The first questionnaire, End of Life Professional Caregiver Survey, included three domains: patients and family-centered communication, cultural and ethical values, effective care delivery. The Intensity of Interprofessional Collaboration Scale included two subscales: care sharing activities, and interprofessional coordination. In total, 697 LTC staff were given surveys, including personal support workers, support staff (housekeeping, kitchen, recreation, laundry, dietician aids, office staff), and registered staff (licensed nurses, physiotherapists, social workers, pharmacists, physicians). RESULTS: A total of 317 participants completed the survey (126 personal support workers, 109 support staff, 82 registered staff) for a response rate of 45%. Significant differences emerged among occupational groups across all scales and subscales. Specifically, support staff rated their comfort of working with dying patients significantly lower than both nurses and PSWs. Support staff also reported significantly lower ratings of care sharing activities and interprofessional coordination compared to both registered staff and personal support workers. CONCLUSIONS: These study findings suggest there are differing educational needs and sense of interprofessional collaboration among LTC staff, specific to discipline group. Both the personal support workers and support staff groups appeared to have higher needs for education; support staff also reported higher needs related to integration on the interdisciplinary team. Efforts to build capacity within support staff related to working with dying residents and their families are needed. Optimal palliative care may require resources to increase the availability of support for all staff involved in the care of patients.

This work designs a non-coherent impulse basedtransceiver operating in a frequency range of 3.1-10.6 GHz for medical sensing applications. The transmitter consists of an ON/OFF Keying data modulator, a Gaussian pulse generator, and a variable gain amplifier to control the transmitting pulse level. The receiver consists of an LNA, a multiplier, an integrator, and a comparator. The IC is designed using 0.18 microm CMOS technology with a supply voltage of 1.8 V. The simulated pulse width is 0.2 ns and the maximum pulse rate is over 1 GHz. A heart motion detection performance was demonstrated with high precision for an overall power consumption of 40 mW. This design can also be modified to be used in wireless UWB data communications to build a complete low power wireless sensor node.

The current status of evaluation and management provided by individual healthcare professionals (HCP) at amyotrophic lateral sclerosis (ALS) centers and clinics needs to be analyzed. This paper describes one ALS center's experiences with the development, analysis, refinement, and utility of an interdisciplinary, HCP-driven ALS database. The purpose and conceptual framework of the database, the general data that needed to be collected, and the types of reports that needed to be generated were determined, and, in collaboration with a computer programmer, data entry and database management systems were developed. Data were collected on 234 patients between September 1996 and August 1998, and were analyzed by a biostatistician. Based on review of the biostatistician's report and discussion of problems encountered with the systems, the database was then refined. Benefits of the database system included: systematization of data collection and reporting, reduction of redundant data collection by individuals, decreased variability of evaluation methods and management decisions from patient to patient, and increased availability of a variety of uniform patient information to assist team members in making care decisions. Ongoing refinement will ensure that this HCP-driven ALS database continues to be informative, practical and effective for decision-making and enhancing delivery of care.

BACKGROUND: A study was conducted to: (1) establish the feasibility and reliability of the Spiritual Well-Being Scale (SWBS) and its religious (RWB) and existential well-being (EWB) subscales in a sample of individuals with ALS; (2) describe the spiritual and religious practices, and spiritual well-being in these individuals; and (3) examine the relationship between spiritual well-being and quality of life. METHOD: A random sample of 60 individuals completed the SWBS at the beginning and end of an ALS clinic visit. Subjects were classified into early, middle or late stage of ALS, using vital capacity and total ALS Functional Rating Scale scores. A subsample completed the Sickness Impact Profile (SIP). RESULTS: The SWBS and its RWB and EWB subscales were found to have high internal consistency and test-retest reliability. There were no statistically significant differences in SWB, RWB or EWB scores among the three stages of ALS. RWB scores were significantly higher than EWB scores overall and within the middle and late stages. Strong negative correlations were found between physical and psychosocial dimension SIP subscores and RWB scores, suggesting that religious well-being may impact quality of life, or vice versa.

BACKGROUND AND PURPOSE: This case report describes the use of Sinaki and Mulder's approach to staging amyotrophic lateral sclerosis (ALS) and functional outcome measures in designing a treatment program for a 59-year-old woman with ALS. CASE DESCRIPTION AND OUTCOMES: As the patient progressed from stage I through stage VI, over 12 months, the physical therapy goals changed from optimizing remaining function, to maintaining functional mobility, and finally to maximizing quality of life. DISCUSSION: Disease staging and the use of functional outcome measures provide a framework for physical therapy evaluation and treatment of patients with ALS throughout the disease process. Physical therapists can assist patients with ALS through the provision of education, psychological support, rehabilitation programs, and recommendations for appropriate equipment and community resources.
