Effect of life-space mobility on subjective well-being in aged home-based rehabilitation users with different levels of independence in activities of daily living.

[Purpose] The relationship between quality of life and life-space mobility in community-dwelling older adults has recently been reported. The present study aimed to elucidate this relationship in home-based rehabilitation users with limited life-space mobility and loss of independence in activities of daily living. [Participants and Methods] The study population comprised 33 home-based rehabilitation users. The participants were expected to have a wide range of the level of independence in activities of daily living; therefore, they were categorized into three groups according to the Barthel Index score: independent (95–100 points), moderately disabled (90–65 points), and severely disabled (60–0 points) groups. We examined the relationships among the Philadelphia Geriatric Center Morale Scale, Life-Space Assessment, and Barthel Index scores and age. [Results] We detected a strong positive correlation between the Philadelphia Geriatric Center Morale Scale and Life-Space Assessment scores in the independent group; however, no significant correlations were observed in the moderately and severely disabled groups. [Conclusion] Our findings suggest a relationship between subjective well-being and life-space mobility in home-based rehabilitation users who are mostly independent in activities of daily living. However, owing to the small sample size and characteristics of the scales used in this study, further studies are warranted to verify these results.

Self-efficacy and Physical Function in Cancer Survivors Receiving Home-visit Rehabilitation

ABSTRACTObjectives:Home-visit rehabilitation is critical for cancer patients because it facilitates recovery. However, few studies have reported relevant information and practices concerning this patient support. This study investigated the factors influencing the self-efficacy of cancer survivors receiving home-visit rehabilitation compared with non-cancer home-visit rehabilitation users by matching propensity scores.Methods:The present study was a cross-sectional study involving participants from two cancer care institutions. Fifteen cancer survivors who received home-visit rehabilitation (9 men, 6 women; age=77.6±11.1 years) were matched for their propensity scores (adjusted for age, sex, and comorbidity) with 15 home-visit rehabilitation users without cancer (8 men, 7 women; age=74.7±11.7 years). Self-efficacy was measured based on the self-efficacy for activities of daily living (SEADL) scale and self-efficacy for going out among community-dwelling elderly people (SEGE) scale. Grip strength (GS), 30-second chair stand test (CS-30), Functional Independence Measure (FIM), and Life-Space Assessment (LSA) were measured based on objective evaluation items.Results:In cancer survivors, the SEADL was significantly correlated with GS, CS-30, FIM, motor-FIM (mFIM), and LSA. The CS-30 of cancer survivors was significantly correlated with SEGE. Among home-visit rehabilitation users without cancer, although the correlation between SEADL and FIM or mFIM was significant, SEGE was not significantly correlated with the other measurements.Conclusions:When compared with home-visit rehabilitation users without cancer, self-efficacy among cancer survivors was influenced not only by activities of daily living but also by physical function and life-space mobility.

Elective Foot & Ankle Procedures in the Geriatric Populations: Worth the Mobility Gains

Category:Ankle; Hindfoot; Midfoot/ForefootIntroduction/Purpose:Chronic, non-traumatic pathologies of the foot and ankle can be mobility-limiting for patients of all ages. Given increased rates of perioperative comorbidities and the heightened risks of intraoperative complications, physicians may be more inclined to manage elderly patients with longer periods of conservative treatment for similar pathologies. However, previous work has shown that decreased mobility of elderly patients affects longevity and is linked to increased rates of all-cause and non- cancerous morbidity and mortality. Currently, little is known about the effect of elective foot and ankle procedures on mobility in patients of all ages. Therefore, the objective of this study was to compare posteroperative changes in LifeSpace Mobility Assessment (LSA) scores of adult and elderly patients following foot and ankle surgery.Methods:A prospective study of 184 patients undergoing elective ankle, hindfoot, and midfoot procedures conducted by a single surgeon between September 1, 2015 and August 31, 2019 was undertaken following IRB approval. Patient-reported LSA scores were collected at preoperative and routine 6-month and 12-month follow-up clinic appointments. Patient demographic and surgical data were recorded, and they were divided into groups by age over and under 65 years. Demographics and surgical characteristics were compared utilizing an independent sample t-test for continuous, normally distributed data and a chi-squared or Fischer's exact test for categorical data. Alpha and beta were assumed to be 0.05 and 0.8, respectively.Results:The younger (<65) group included 140 patients (mean age 44.1, SD 13.2), while 44 patients were observed in the elderly (>=65) age group (mean age 70.4 years, SD 8.4 (p<0.0001). The elderly group had significantly more patients with hypertension requiring medical management (p=0.012), but no other differences in perioperative comorbidities or demographics were observed. A higher proportion of elderly patients underwent surgery for conditions of osteoarthric origin, while younger patients underwent surgery more frequently for soft tissue pathology (p=0.033). The average LSA score of elderly patients at the preoperative visit was 58.3 (SD 38.0) versus 79.3 (SD 38.8) in the younger cohort (p=0.041). Both the young and elderly patient cohorts regained and surpassed their preoperative mobility scores by 6 months and 1-year postop. No difference in average mobility score was observed between young (85.6, SD 36.1) and elderly (90.1, SD 34.3) cohorts at 1-year follow-up.Conclusion:This study demonstrates that while elderly patients may begin with lower mobility than younger patients with foot and ankle pathology, operative treatment can improve their mobility dramatically up to comparable levels of operatively-treated younger patients. Our results, in tandem with literature showing the drastic deleterious effects of decreased mobility in the elderly, suggest that the discussion to pursue or hold on surgical correction of chronic foot and ankle disease in the patients over the age of 65 must take into account the mobility benefits of surgery.

Precisão da medida de mobilidade no espaço de vida para discriminar fragilidade e sarcopenia em idosos

Abstract Objective To identify the profile of a sample of older people recruited at home based on a measure of life-space mobility and to establish the accuracy of the cut-off points of this instrument for discriminating between levels of frailty, frailty in walking speed and risk of sarcopenia. Method An observational methodological study of 391 participants aged ≥72 (80.4±4.6) years, who answered the Life-Space Assessment (LSA) and underwent frailty and risk of sarcopenia screening using the frailty phenotype and SARC-F measures, respectively, was performed. The cut-off points for frailty and risk of sarcopenia were determined using ROC (Receiver Operating Characteristic) curves and their respective 95% confidence intervals. Results Mean total LSA score was 53.6±21.8. The cut-off points with the best diagnostic accuracy for total LSA were ≤54 points for frailty in walking speed (AUC=0.645 95%; p&lt;0.001) and ≤60 points for risk of sarcopenia (AUC=0.651 95%; p&lt;0.001). Conclusion The ability of older people to move around life-space levels, as assessed by the LSA, proved a promising tool to screen for frailty in walking speed and risk of sarcopenia, thus contributing to the prevention of adverse outcomes.

Marked Mobility Improvement: Men and Women Respond Similarly to Operative Treatment of Foot &amp; Ankle Pathologies

Category:Ankle; HindfootIntroduction/Purpose:Differences between men and women in the perception, incidence, and outcomes of various orthopaedic injuries are well-documented. Recent studies have noted that women display increased ankle ligamentous laxity and double the rate of ankle sprains in relation to their male peers. Current studies indicate that, in general, women and men respond similarly to surgical correction of such pathologies. However, a gender difference in mobility has not been investigated. Given the mobility implications associated with chronic foot and ankle conditions, a need exists to better characterize baseline and postoperative functionality in men and women. The objective of this study was to assess changes in LifeSpace Mobility Assessment (LSA) scores of male and female patients following surgical correction of non-traumatic ankle, hindfoot, and midfoot conditions.Methods:A prospective study of elective ankle, hindfoot, and midfoot procedures conducted by a single surgeon between September 1, 2015 and August 31, 2019 was undertaken following IRB approval. LSA scores on 184 patients - 137 women and 53 men - were collected at preoperative, 3-month, 6-month, and 12-month clinic visits. The electronic medical record was queried for patient demographic and surgical data. Demographics, surgical factors, and patient-reported LSA scores were compared utilizing an independent sample t-test for continuous, normally distributed data. All categorical data was analyzed with a chi- squared or Fischer's exact tests. Alpha and beta were set at 0.05 and 0.8, respectively.Results:The average age of female participants was 51.2 (SD 16.4) years and 48.2 (SD 17.1) years for male participants (p=0.273). There were no significant differences in frequencies of comorbidities (p>0.05). Men and women in this cohort underwent elective foot and ankle surgery for a similar diseases processes, most commonly soft tissue pathology, followed by osteoarthritis (p=0.440). Women had significantly lower LSA scores at preoperative (63.7 [SD 38.1] vs. 84.8 [SD 35.9], p=0.002), 3 month postoperative (52.5 [SD 33.8] vs. 69.9 [SD 34.5], p=0.006), and 1 year postoperative (81.2 [SD 37.2] vs. 105.5 [SD 18.2], p=0.019) timepoints relative to their male peers. No differences in mobility at 6 months postop were observed (p=0.714). Overall, women and men had similar absolute increases in postoperative mobility at 1-year after surgery (17.5 vs. 20.7, p>0.05) as well as similar percentage of increased mobility (27% vs. 24%, p>0.05).Conclusion:The present study provides further evidence of the gender differences in chronic foot and ankle pathologies. Both sexes improved similarly pre to postoperatively, however, women did not reach the same level of absolute mobility as their male counterparts. Prior studies have shown that women characterize a greater degree of limitation with foot and ankle conditions as 'normal' relative to men, making it plausible that they delay treatment until they become more severely symptomatic than men. This persistent deficit highlights the importance of early recognition of mobility impairment in order to preserve function among the sexes in foot and ankle care.

Calculation of Minimally Clinically Important Difference in VAS, SF-36, and LSA Scores for Hallux Rigidus Correction Via MTP Fusion

Category:Bunion; Midfoot/Forefoot; OtherIntroduction/Purpose:Hallux rigidus is a mobility limiting disease commonly seen in elderly patient populations. Correction via metatarsophalangeal (MTP) fusion has been shown to be a safe and effective means of treatment in these populations relative to younger cohorts. An increasingly important measure of surgical efficacy is the establishment of patient-reported outcomes for achieving meaningful change through a procedure. Calculation of a minimally clinically important difference (MCID) has been established to illuminate these thresholds. The objective of this study was to calculate MCID thresholds for visual analogue pain (VAS), Short Form 26 Health survey (SF-36), and LifeSpace Mobility Assessment (LSA) following first MTP fusion.Methods:A prospective study of all patients undergoing MTP fusion between August 1, 2015 and July 1, 2018 by a single surgeon was conducted following IRB approval. A total of 143 patients were included in the study. Demographics and surgical data were collected from review of the electronic medical record. Patient reported VAS, SF-36, and LSA scores were collected at routine 6- month and 12-month follow-up clinic appointments, as well as preoperatively. This study utilized a distribution-based approach for calculation of MCID for each of the patient reported outcomes. The MCID was defined as 0.5 times the standard deviation of the pre-operative score, 95% bootstrap confidence intervals were creating using the bias corrected and accelerated method.Results:The average age of patients undergoing first MTP fusion was 63.4 years (SD 10.6). Patient demographics were recorded, 25.9% of patients were current or former smokers, 60.8% had clinically managed hypertension, 9.8% had diabetes, and 31.5% carried a diagnosis of osteoarthritis. The average patient had 1.9 (SD 1.1) toes operated on during the procedure, including their MTP fusion. Mean tourniquet time was 65.6 (SD 24.8) minutes and mean operative time was 89.9 (SD 31.4) minutes. Mean (SD): VAS, 4.7 (2.8); LSA, 86.4 (35.1); SF-36 physical component score, 63.00 (19.9); SF-36 component score, 77.4 (19.8). MCID: VAS, 1.4 (95% CI 1.3 to 1.5); LSA, 17.6 (95% CI 14.4 to 21.4); SF-36 physical component score, 9.9 (95% CI 9.1 to 11.0); SF-36 mental component score, 9.8 (95% CI 8.7 to 11.4).Conclusion:This study identifies the MCID for VAS, SF-36, and LSA following first MTP fusion. The MCID of VAS reveals minimal improvements in pain (>1.5) are clinically significant. Both SF-36 physical and mental component scores reveal narrow 10- point differences have clinically significant changes. In contrast, LSA appears to have a relatively wide MCID value for patients undergoing first MTP fusion, highlighting the need for a large increase in mobility for significant improvement.

Associations Between Perceived Physical and Mental Fatigability and Life Space Mobility in Older Men: The MrOS Study

Physical performance and fatigue can limit mobility within the larger environment (life-space mobility). It is unknown whether perceived fatigability, fatigue anchored to activity intensity and duration, is independently associated with life-space. We assessed this cross-sectionally in the Osteoporotic Fractures in Men Study (MrOS; N=1,681, Meanage=85±4.1). The Pittsburgh Fatigability Scale (PFS, range: 0-50) measured physical (Mean=16.2±9.5) and mental fatigability (Mean=7.5±8.0). Life Space Assessment scores (range: 0-120, higher=greater life-space) incorporated level, frequency, and assistance used for life-space mobility (Mean=84.3±22.0). Compared to the lowest fatigability strata (Physical: PFS 0-4; Mental: PFS 0-3, modeled separately), men in the two highest physical strata (PFS 20-24: B=-4.10±1.67; PFS≥25: B=-6.23±1.72; p’s≤.05) and men in the three highest mental strata reported significantly lower life-space mobility (PFS 13-15: B=-3.42±1.74; PFS 16-19: B=-5.38±1.83; PFS≥20: B=-7.96±1.66, p’s≤.05), adjusted for physical performance and health covariates. Our results provide evidence linking fatigability and real-world mobility, independent of physical health, in older men.

Intrinsic Capacity and Its Relationship With Life Space Area (INCREASE) in Community-Dwelling Older Adults

Intrinsic capacity (IC), defined as ‘the composite of all physical and mental capacities of an individual’, is of increasing interest in geriatrics as a potential multidimensional measure of health in older adults. According to the International Classification of Functioning, Disability and Health (ICF) framework, IC, through its interactions with environmental factors, determines a person’s participation in the community. However, there is lack of empirical evidence demonstrating this association. The primary aim of this study was to examine the association of IC with Life Space Area (LSA; a measure of participation) among community-dwelling older adults. The secondary aim was to determine whether age and gender modify this relationship. Cross sectional analysis was performed on data from the Individual Physical Proficiency Test for Seniors (IPPT-S) study conducted in the Northeastern region of Singapore. Standardized IC factor scores were calculated through confirmatory factor analysis using variables that represented the 5 IC domains. Association of IC with LSA and its effect modification by age and gender were examined with regression analyses. The study included 751 participants with mean age of 67.6 and mean LSA score of 88.6. IC showed a positive and significant association with LSA (B=6.33, P<0.001) and the effect remained significant even after controlling for potential confounders (B=4.76, P<0.001). Age and gender did not show significant modification on this relationship. Our findings support the empirical rigour of the ICF framework and provide guidance for healthcare providers who aim to enhance life space mobility and promote healthy aging in older adults.

Physical and Cognitive Correlates of GPS-Derived Life-Space Characteristics in Older Adults

Life-space mobility, movement within one’s living environment, is important for functional independence in later life. It is unclear which life-space characteristics (i.e., space, duration, shape) are most affected by physical and cognitive limitations. GPS-derived measures mitigate recall bias and offer novel ways to characterize life-space. We examined associations between physical and cognitive performance and GPS-derived life-space characteristics. Participants were 164 community-dwelling adults (Age: M=77.3±6.5) from baseline data of a clinical trial to improve walking in older adults. Participants carried a portable GPS for 7 days, which passively collected real-time location. Standard deviational ellipses (SDEs) and minimum convex polygons (MCPs) were derived for each day. Area and compactness of these measures quantified activity space and shape, respectively. For each measure, 7-day medians and median absolute deviations (MAD) were computed to capture both central tendency and variability of weekly activity. Activity duration was quantified as percentage of time outside home. Adjusting for age and sex, percent time outside home was associated with lower mobility performance (i.e., 6-minute walk (6MWT), figure 8 walk, ρ’s=.17-.18, p’s<.05) and executive functioning (i.e., Trail Making Test, Part A: ρ=.16, p=.04, Part B: ρ=.19, p=.01). Median MCP and SDE areas, but not compactness, were associated with 6MWT performance (ρ’s=.18-.20, p’s<.05). MCP area MAD was associated with greater global cognition (3MSE, ρ=.15, p=.05). Life-space characteristics were differentially associated with performance measures, suggesting physical and cognitive limitations may constrain life-space mobility via different mechanisms. Variation in these associations by neighborhood walkability and active versus passive travel will also be examined.

Differential Influence of COVID-19 pandemic on Life-Space Mobility of older adults

Older adults often experience functional decline during hospitalization as a result of immobility. Such decline has associated adverse outcomes, including gait instability, falls, pressure injuries, delirium, and new nursing home admissions. Our objective was to create an effective and sustainable in-hospital mobility program through enhanced interdisciplinary cooperation in an Acute Care of the Elderly (ACE) unit. An interdisciplinary team at UNC’s 25-bed ACE unit planned and delivered enhanced patient mobility beginning in July 2020. We used an input-process-output model to design and analyze an intervention based on enhanced collaboration. Inputs included a mobility taskforce which was comprised of physicians, nurses, physical and occupational therapists, and quality improvement specialists. Through regular meetings, each taskforce member contributed to the study design and were empowered to identify barriers to implementation. Outputs included stakeholder engagement and mobility rates. Early results show a doubling in mobility rates over a 6-month period with consistent and enthusiastic stakeholder engagement. Observations of such benefits include: a) stakeholder inclusion from each discipline ensured implementation that was pragmatic and easily incorporated into the daily workflow; b) mobility champions regularly disseminated information to their respective disciplines, leading to changes using a quality improvement process; and c) barriers to implementation were rapidly identified, and mobility champions were motivated to find solutions, allowing cohesive incorporation of a broad spectrum of priorities. An interprofessional team model is effective to mobilize hospitalized older adults, potentially reducing adverse hospital outcomes. Successful implementation of such programs is dependent on interprofessional collaboration.

Can probability neglect bias promote social distancing during the COVID-19 pandemic?

The effectiveness of a stay-at-home order depends on the speed of behavioral changes that are triggered by risk perception. Probability neglect bias, one of the cognitive biases, may lead people to engage in social distancing. However, there is no empirical evidence of the relationship between probability neglect bias and social distancing. This study aims to examine the relationship between individual differences in susceptibility to probability neglect bias and the level of social distancing practice during the early stages of the COVID-19 outbreak in Japan. The level of engagement in social distancing was defined as the narrowing of life-space mobility. We conducted a web-based questionnaire survey among 1000 adults living in central Tokyo, Japan, at the beginning of the pandemic outbreak. Our results show that people had a strong fear of infection in the early pandemic stages. Approximately 60% of our subjects were influenced by probability neglect bias. People susceptible to probability neglect bias engaged in social distancing more intensely than those who were not susceptible after the state of emergency was lifted.

Longitudinal changes in life-space mobility and the factors influencing it among chronic community-dwelling post-stroke patients

Purpose To identify longitudinal changes in life-space mobility and the factors influencing it among chronic, stable post-stroke patients. Materials and methods This prospective study included Japanese post-stroke patients who received day-care rehabilitation services and could undergo three life-space mobility assessments (at baseline, 12, and 24 months) for over 2 years, using the Life-Space Assessment (LSA) tool. Physical function, cognitive function, and activities of daily living were assessed by self-selected comfortable gait speed, Mini-Mental State Examination (MMSE), and Functional Independence Measure Motor subscale (FIM motor) scores, respectively, in addition to age, sex, time from onset, stroke type, and comorbidities. A multivariable linear mixed-effects model was used to examine the longitudinal changes in LSA scores and associated factors. Results A total of 89 participants were enrolled. At baseline, the median age was 74 years, 33% were women, and median time from onset was 75 months. The LSA scores significantly declined over the two-year period. In the multivariate linear mixed-effects model adjusted for clinical characteristics, comfortable gait speed and age were significantly associated with changes in the LSA score, independent of FIM motor scores and MMSE scores. Conclusions Life-space mobility may persistently decline, and gait function may be a determinant influencing these changes in community-dwelling chronic post-stroke patients. Implications for Rehabilitation Limited life-space mobility leads to less frequent participation in social activities and an increased risk of adverse health outcomes such as hospitalization. Changes in life-space mobility should be considered in the rehabilitation care plan for chronic post-stroke patients. Life-space mobility may decline persistently in stable post-stroke patients, even if they have periodically received day-care rehabilitation services. Since gait speed is a predominant factor affecting life-space mobility, regular assessment of gait function and appropriate strategies are needed to prevent deterioration of gait speed in chronic post-stroke patients.

Use of estrogen supplementation is associated with higher quality of life scores in women with cystic fibrosis

The association of estrogen supplementation use and quality of life in women with cystic fibrosis (CF) is not well characterized. In this cross-sectional study, women with CF completed quality of life questionnaires during a routine CF clinic visit. The use of estrogen supplementation was associated with higher quality of life scores in all domains of the CF questionnaire-revised (CFQ-R) and was significant in the role limitations and respiratory domains. Most participants who were not currently using estrogen supplementation had previously used estrogen supplementation. Most participants had used estrogen to regulate menses, prevent pregnancy and control symptoms around menses. Use of estrogen supplementation was not associated with differences in life-space mobility or screening for sexual dysfunction. This is the largest study to date investigating the association of estrogen supplementation and quality of life in women with CF. Prospective randomized studies are needed to clarify the association of estrogen supplementation and quality of life in women with CF.

Predicting Autonomous Shuttle Acceptance in Older Drivers Based on Technology Readiness/Use/Barriers, Life Space, Driving Habits, and Cognition

Shared autonomous vehicle services (i. e., automated shuttles, AS) are being deployed globally and may improve older adults (>65 years old) mobility, independence, and participation in the community. However, AS must be user friendly and provide safety benefits if older drivers are to accept and adopt this technology. Current potential barriers to their acceptance of AS include a lack of trust in the systems and hesitation to adopt emerging technology. Technology readiness, perceived ease of use, perceived barriers, and intention to use the technology, are particularly important constructs to consider in older adults' acceptance and adoption practices of AS. Likewise, person factors, i.e., age, life space mobility, driving habits, and cognition predict driving safety among older drivers. However, we are not sure if and how these factors may also predict older adults' intention to use the AS. In the current study, we examined responses from 104 older drivers (Mage = 74.3, SDage = 5.9) who completed the Automated Vehicle User Perception Survey (AVUPS) before and after riding in an on-road automated shuttle (EasyMile EZ10). The study participants also provided information through the Technology Readiness Index, Technology Acceptance Measure, Life Space Questionnaire, Driving Habits Questionnaire, Trail-making Test Part A and Part B (TMT A and TMT B). Older drivers' age, cognitive scores (i.e., TMT B), driving habits (i.e., crashes and/or citations, exposure, and difficulty of driving) and life space (i.e., how far older adults venture from their primary dwelling) were entered into four models to predict their acceptance of AVs—operationalized according to the subscales (i.e., intention to use, perceived barriers, and well-being) and the total acceptance score of the AVUPS. Next, a partial least squares structural equation model (PLS-SEM) elucidated the relationships between, technology readiness, perceived ease of use, barriers to AV acceptance, life space, crashes and/or citations, driving exposure, driving difficulty, cognition, and intention to use AS. The regression models indicated that neither age nor cognition (TMT B) significantly predicted older drivers' perceptions of AVs; but their self-reported driving difficulty (p = 0.019) predicted their intention to use AVs: R2 = 6.18%, F (2,101) = 4.554, p = 0.040. Therefore, intention to use was the dependent variable in the subsequent PLS-SEM. Findings from the PLS-SEM (R2 = 0.467) indicated the only statistically significant predictors of intention to use were technology readiness (β = 0.247, CI = 0.087-0.411) and barriers to AV acceptance (β = −0.504, CI = 0.285-0.692). These novel findings provide evidence suggesting that technology readiness and barriers must be better understood if older drivers are to accept and adopt AS.

Exploration of pediatric manual wheelchair confidence among children, parents, and occupational therapists: a qualitative study

Purpose Manual wheelchair (MWC) confidence is a predictor of adult life-space mobility and social participation. To date, scientific literature specific to pediatric MWC confidence is scarce which prevents in-depth understanding. The objective of this study was to explore the perceptions of pediatric MWC users (PMWU), parents, and occupational therapists regarding pediatric MWC confidence. Methods Five focus groups were conducted with PMWUs (n = 12) and occupational therapists (n = 9), and semi-structured interviews were conducted with parents of PMWUs (n = 2). Inductive thematic analysis was performed following verbatim transcription of audio recorded material. Results Three overarching themes were identified across PMWUs, parents, and occupational therapists: (1) “MWC confidence is not a clinical priority” depicted the construct’s varying level of clinical priority and perceived abstractness; (2) “MWC confidence is both a child and parent consideration” revealed nuances between the PMWU’s MWC confidence and the parents’ perception of the PMWU’s MWC confidence; and (3) “Opportunities to develop MWC confidence are context-specific” contrasted afforded and unafforded opportunities to experience independent MWC mobility. Conclusions Pediatric MWC confidence is an important aspect of wheelchair use that is shaped by a multitude of factors in PMWU’s lives. This new area of pediatric study provides support for the need to measure this important construct. IMPLICATIONS FOR REHABILITATION This study is the first to explore children’s, parents’, and occupational therapists’ perceptions of pediatric MWC confidence. Pediatric MWC confidence impacts MWC use in a multifaceted fashion. Future studies should consider the development and validation of a self-report measure to assess pediatric MWC confidence.

Relationship Between Life-Space Mobility and Health Characteristics in Older Adults Using Global Positioning System Watches.

This study aimed to examine the feasibility of using global positioning system (GPS) watches to examine relationships between GPS-based life-space mobility (LSM) metrics and self-report LSM and health measures (physical, psychological, and cognitive function) among older adults. Thirty participants wore a Fitbit Surge for 3days. Eight spatial and temporal LSM measures were derived from GPS data. About 90% of in-home movement speeds were zero, indicating the sedentary lifestyle, but they made some active out-of-home trips as the total distance traveled and size of movement area indicated. There was a significant difference in total distance traveled and 95th percentile of movement speed between mild cognitive and intact cognition groups. GPS-based higher proportion of out-of-home time was significantly associated with greater functional fitness. Greater GPS use hours were significantly associated with higher cognition. These findings suggest the potential of GPS watches to continuously monitor changes in functional health to inform prevention efforts.

Positive Self-Perceptions of Aging Play a Significant Role in Predicting Physical Performance among Community-Dwelling Older Adults.

Self-perceptions of aging (SPA) is associated with various health-related outcomes, including physical performance. No previous study has investigated the potential predictive influence of SPA on physical performance among Swedish community-dwelling older adults. This was a cross-sectional study using a random sample of 153 Swedish community-dwelling individuals aged 70 and older. Multiple logistic regression analysis was performed, using the subscale “Attitude Towards Own Aging” of the Philadelphia Geriatric Center Morale Scale, as a measure of SPA. The Short Physical Performance Battery (SPPB) was dichotomized and used as the outcome variable. SPA was a significant predictor (OR = 1.546, CI = 1.066–2.243) of physical performance, adjusted for age, cognitive function, and life-space mobility. Further analyses revealed significant sex differences, with SPA not being included in the model for the men whilst it was still a significant predictor (OR = 1.689, CI = 1.031–2.765) of physical performance in the group of women. SPA plays a significant role in predicting physical performance among Swedish community-dwelling older adults. To further clarify this relationship and its consequences, future longitudinal research should focus on the relationship between SPA, physical performance, and fall risk.

Requirements of a\xa0cognitive-motor spatial orientation training for nursing home residents: an\xa0iterative feasibility study

A sedentary lifestyle in nursing home residents is often accompanied with reduced life space mobility and in turn affects satisfaction with life. One of the reasons for this may be limited ability to find one’s way around the care facility and its environment. However, spatial orientation exercises might reduce these problems if they are integrated into an adequate cognitive-motor training. Therefore, we integrated six novel and target group-specific spatial orientation exercises into an established multicomponent cognitive-motor group training for nursing home residents and evaluated its feasibility. Forty nursing home residents (mean age: 87.3 ± 7 years) participated in the spatial orientation cognitive motor training (45–60 min, twice a week over a period of 12 weeks). The main outcomes included the feasibility criteria (adherence, completion time, acceptance, instructions, motor performance, materials/set up, complexity) and first measurements of mobility and satisfaction with life (SPPB [Short Physical Performance Battery], SWLS [Satisfaction with Life Scale]). Adherence increased over time. The increase was associated with the adaptions and modifications of the spatial orientation exercises that were made to meet the participants’ requirements. A positive trend was discerned for mobility and life satisfaction, comparing pre- and posttraining data. In summary, the feasibility analysis revealed that future interventions should consider that (a) instructions of demanding spatial tasks should be accompanied by an example task, (b) trainers should be encouraged to adjust task complexity and materials on an individual basis, (c) acceptance of the training should be promoted among nursing staff, and (d) surroundings with as little disturbance as possible should be selected for training.

Changes in older adults' life space during lung cancer treatment: A mixed methods cohort study.

Maintenance of function during cancer treatment is important to older adults. Characteristics associated with pretreatment life-space mobility and changes during non-small cell lung cancer (NSCLC) treatment remain unknown. This mixed methods cohort study recruited adults age ≥65 with advanced NSCLC starting palliative chemotherapy, immunotherapy, and/or targeted therapy from a Comprehensive Cancer Center, Veterans Affairs, and safety-net clinic. Patients completed geriatric assessments including Life-Space Assessment (LSA) pretreatment and at 1, 2, 4, and 6 months after treatment initiation. LSA scores range from 0 to 120 (greater mobility); LSA <60 is considered restricted. We used mixed-effects models to examine pretreatment LSA, change from 0 to 1month, and change from 1 to 6months. A subgroup participated in semistructured interviews pretreatment and at 2 and 6 months to understand the patient experience of life-space change. For each interview participant, we created joint displays of longitudinal LSA scores juxtaposed with illustrative quotes. Among 93 patients, median age was 73 (range 65-94). Mean pretreatment LSA score was 67.1. On average, LSA declined 10.1 points from pretreatment to 1 month and remained stable at 6 months. Pretreatment LSA score was associated with several demographic, clinical, geriatric assessment, and symptom characteristics. LSA decline at 1 month was greater among patients with high anxiety (slope=-12.6 vs. -2.3, p=0.048). Pretreatment body mass index <21 kg/m2 was associated with LSA improvement from 1 to 6months (slope=4.1 vs. -0.04, p=0.003). Joint displays illustrated the impact of different life-space trajectories on patients' lives in their words. Older adults with NSCLC have low pretreatment life space with many developing restricted life space during treatment. Incorporating life-space assessments into clinical cancer care may help older adults concretely visualize how treatment might impact their daily function to allow for informed decision making and identify early changes in mobility to implement supportive interventions.
