RESUMO
BACKGROUND: While nonpharmacologic treatments are increasingly endorsed as first-line therapy for low back pain (LBP) in clinical practice guidelines, it is unclear if use of these treatments is increasing or equitable. OBJECTIVE: Examine national trends in chiropractic care and physical rehabilitation (occupational/physical therapy (OT/PT)) use among adults with LBP. DESIGN/SETTING: Serial cross-sectional analysis of the National Health Interview Survey, 2002 to 2018. PARTICIPANTS: 146,087 adults reporting LBP in prior 3 months. METHODS: We evaluated the association of survey year with chiropractic care or OT/PT use in prior 12 months. Logistic regression with multilevel linear splines was used to determine if chiropractic care or OT/PT use increased after the introduction of clinical guidelines. We also examined trends in use by age, sex, race, and ethnicity. When trends were similar over time, we present differences by these demographic characteristics as unadjusted ORs using data from all respondents. RESULTS: Between 2002 and 2018, less than one-third of adults with LBP reported use of either chiropractic care or OT/PT. Rates did not change until 2016 when uptake increased with the introduction of clinical guidelines (2016-2018 vs 2002-2015, OR = 1.15; 95% CI: 1.10-1.19). Trends did not differ significantly by sex, race, or ethnicity (p for interactions > 0.05). Racial and ethnic disparities in chiropractic care or OT/PT use were identified and persisted over time. For example, compared to non-Hispanic adults, either chiropractic care or OT/PT use was lower among Hispanic adults (combined OR = 0.62, 95% CI: 0.65-0.73). By contrast, compared to White adults, Black adults had similar OT/PT use (OR = 0.98; 95% CI: 0.94-1.03) but lower for chiropractic care use (OR = 0.50; 95% CI: 0.47-0.53). CONCLUSIONS: Although use of chiropractic care or OT/PT for LBP increased after the introduction of clinical guidelines in 2016, only about a third of US adults with LBP reported using these services between 2016 and 2018 and disparities in use have not improved.

The fastest growing segment of our population is the oldest portion of our population. Rehabilitative care is significantly impacted by this trend - comorbidity, disability, and pain are more prevalent among older adults, resulting in large demands for rehabilitation services as older patients traverse the health care continuum. Unfortunately, despite these circumstances, rehabilitation clinicians frequently are uninformed or intimidated with caring for an older patient. Research studies relevant to geriatric rehabilitation are seldom grounded on key frameworks impacting geriatric rehabilitative care. To address these gaps, in this editorial, we highlight three important frameworks that can help rehabilitation clinicians, educators and researchers alike to better focus their work on the needs and priorities of the older patient.
RESUMO
OBJECTIVE: To identify clinically meaningful thresholds of leg power impairment identified by the stair climb power test (SCPT). DESIGN: Cross-sectional analysis using the baseline data from an observational cohort study. SETTING: The Boston Rehabilitative Impairment Study of the Elderly. PARTICIPANTS: Community-dwelling older adults (N=413). MAIN OUTCOME MEASURES: SCPT and the Short Physical Performance Battery (SPPB). RESULTS: Using the receiver operating characteristic curves and Youden's J statistics, the optimal threshold for the SCPT associated with mobility limitation as defined by an SPPB score ≤9 was 3.07 Watts/kg for men with a sensitivity of 74%, a specificity of 73% and, an area under the curve (AUC) value of 0.78. For women, the optimal threshold was 2.59 Watts/kg with a sensitivity of 83%, a specificity of 69%, and an AUC value of 0.81. The classification and regression tree sensitivity analysis demonstrated similar thresholds, 2.88 Watts/kg and 2.53 Watts/kg for men and women, respectively. CONCLUSIONS: The study identified clinically meaningful thresholds of impairment for the SCPT for mobility limited older primary care patients. These thresholds may be used to inform rehabilitation care to improve functional mobility of older adults and should be validated in larger more representative clinical trials.

In general, COVID-19-related adaptations that transitioned in-person assessments and interventions to a virtual format were not routinely evaluated. We aimed to conduct a process evaluation to examine the impact of COVID-19-related adaptations on a behavior change intervention designed to increase exercise adherence among Veterans with mobility difficulty. We used secondary data from a nonrandomized study to complete a process evaluation examining the intervention's reach, recruitment, fidelity, dose delivered by physical therapists, and the dose received by the 14 participating Veterans. The physical therapist delivered 95% (133/140) of the study's 10 sessions. Sessions with the lowest delivery dose included Sessions 1 and 10 (86%; n = 12/14). The elements with the lowest dose received included using an exercise journal and developing a postintervention plan (86%; n = 12/14). Our COVID-19 adaptations allowed us to provide our intervention to the majority (67%) of eligible participants without a negative impact on fidelity, dose delivered, or dose received.

OBJECTIVE: To determine how often physicians document mobility limitations in visits with older adults, and which patient, physician, and practice characteristics associate with documented mobility limitations. DESIGN: We completed a cross-sectional analysis of National Ambulatory Medical Care Surveys, years 2012-2016. Multivariate analyses were conducted to identify patient, physician, and practice-level factors associated with mobility limitation documentation. SETTING: Ambulatory care visits. PARTICIPANTS: We analyzed visits with adults 65 years and older. Final sample size represented 1.3 billion weighted visits. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: We defined the presence/absence of a mobility limitation by whether any International Classification of Diseases (ICD)-9 or ICD-10 code related to mobility limitations, injury codes, or the patient's "reasons for visit" were documented in the visits. RESULTS: The overall prevalence of mobility limitation documentation was 2.4%. The most common codes were falls-related. Patient-level factors more likely to be associated with mobility limitation documentation were visits by individuals over 85 years of age, relative to 65-69 years, (odds ratio 2.32, 95% confidence interval 1.76-3.07]; with a comorbid diagnosis of arthritis (odds ratio 1.35, 1.18-2.01); and with a comorbid diagnosis of cerebrovascular disease (odds ratio 1.60, 1.13-2.26). Patient-level factors less likely to be associated with mobility limitation documentation were visits by men (odds ratio 0.80, 0.64-0.99); individuals with a cancer diagnosis (odds ratio 0.76, 0.58-0.99); and by individuals seeking care for a chronic problem (relative to a new problem [odds ratio 0.36, 0.29-0.44]). Physician-level factors associated with an increased likelihood of mobility limitation documentation were visits to neurologists (odds ratios 4.48, 2.41-8.32) and orthopedists (odds ratio 2.67, 1.49-4.79) compared with primary care physicians. At the practice-level, mobility documentation varied based on the percentage of practice revenue from Medicare. CONCLUSIONS: Mobility limitations are under-documented and may be primarily captured when changes in function are overt.

OBJECTIVES: (1) To estimate the association between social engagement (SE) and falls; (2) To examine the relation between mild neurocognitive disorder (MNCD) and falls by different levels of SE. DESIGN: We performed a secondary data analysis using prospective cohort study design. SETTING: Primary care. PARTICIPANTS: A total of 425 older adult primary care patients at risk for mobility decline (N=425). As previously reported, at baseline, 42% of participants exhibit MNCD. MAIN OUTCOME MEASURES: The outcome variable was the number of falls during 2 years of follow-up. Exposure variables at baseline included (1) MNCD identified using a cut-off of 1.5 SD below the age-adjusted mean on at least 2 measures within a cognitive performance battery and (2) SE, which was assessed using the social component of the Late-Life Function and Disability Instrument. High SE was defined as having a score ≥ median value (≥49 out of 100). All models were adjusted for age, sex, education, marital status, comorbidities, and pain status. RESULTS: Over 2 years of follow-up, 48% of participants fell at least once. MNCD was associated with a higher rate of falls, adjusting for the covariates (Incidence Rate Ratio=1.6, 95% confidence interval: 1.1-2.3). There was no significant association between MNCD and the rate of falls among people with high SE. In participants with low SE (having a score less than 49.5 out 100), MNCD was associated with a higher rate of falls as compared with participants with no neurocognitive disorder (No-NCD). CONCLUSIONS: Among participants with low SE, MNCD was associated with a higher rate of falls, but not among participants with high SE. The findings suggest that high SE may be protective against falls among older primary care patients with MNCD.

RATIONALE & OBJECTIVE: For older adults, maintaining mobility is a major priority, especially for those with advanced chronic diseases like kidney failure. However, our understanding of the factors affecting mobility in older adults receiving maintenance hemodialysis is limited. STUDY DESIGN: Descriptive qualitative study. SETTING & PARTICIPANTS: Using purposive sampling, we recruited (1) persons aged≥60 years receiving maintenance hemodialysis; and (2) care partners (≥18 years) providing regular support to an older adult receiving hemodialysis. During a single in-person home visit, we assessed mobility using the Short Physical Performance Battery (SPPB) and conducted individual one-on-one interviews regarding important personal factors related to mobility. ANALYTICAL APPROACH: Descriptive statistics were used for demographic and SPPB data. Transcripts underwent thematic coding, informed by the International Classification of Function framework of mobility. We used conceptual content analysis to inductively extract themes and subthemes. RESULTS: We enrolled 31 older adults receiving hemodialysis (42% female, 68% Black) with a mean age of 73±8 years and mean dialysis vintage of 4.6±3.5 years; their mean SPPB score was 3.6±2.8 points. Among 12 care partners (75% female, 33% Black), the mean age was 54±16 years and mean SPPB score was 10.1±2.4 points. Major themes extracted were (1) mobility represents independence; (2) mobility is precarious; (3) limitations in mobility cause distress; (4) sources of encouragement and motivation are critical; and (5) adaptability is key. LIMITATIONS: Modest sample from single geographic area. CONCLUSIONS: For older adults receiving hemodialysis, mobility is severely limited and is often precarious in nature, causing distress. Older adults receiving hemodialysis and their care partners have identified sources of encouragement and motivation for mobility, and cite an adaptable mindset as important. Future studies should conceptualize mobility as a variable condition and build on this outlook of adaptability in the development of interventions.

This study aimed to evaluate whether gait speed and grip strength predicted clinical outcomes among older adults with blood cancers. We prospectively recruited 448 patients aged 75 years and older presenting for initial consultation at the myelodysplastic syndrome/leukemia, myeloma, or lymphoma clinic of a large tertiary hospital, who agreed to assessment of gait and grip. A subset of 314 patients followed for ≥6 months at local institutions was evaluated for unplanned hospital or emergency department (ED) use. We used Cox proportional hazard models calculated hazard ratios (HRs) and 95% confidence intervals (CIs) for survival, and logistic regression to calculate odds ratios (ORs) for hospital or ED use. Mean age was 79.7 (± 4.0 standard deviation) years. After adjustment for age, sex, Charlson comorbidity index, cognition, treatment intensity, and cancer aggressiveness/type, every 0.1-m/s decrease in gait speed was associated with higher mortality (HR, 1.20; 95% CI, 1.12-1.29), odds of unplanned hospitalizations (OR, 1.33; 95% CI, 1.16-1.51), and ED visits (OR, 1.34; 95% CI, 1.17-1.53). Associations held among patients with good Eastern Cooperative Oncology Group performance status (0 or 1). Every 5-kg decrease in grip strength was associated with worse survival (adjusted HR, 1.24; 95% CI, 1.07-1.43) but not hospital or ED use. A model with gait speed and all covariates had comparable predictive power to comprehensive validated frailty indexes (phenotype and cumulative deficit) and all covariates. In summary, gait speed is an easily obtained "vital sign" that accurately identifies frailty and predicts outcomes independent of performance status among older patients with blood cancers.

OBJECTIVE: Mobility limitation and cognitive decline are related. Metabolic syndrome (MetS), the clustering of three or more cardiovascular risk factors, is associated with decline in both mobility and cognition. However, the interrelationship among MetS, mobility, and cognition is unknown. This study investigated a proposed pathway where cognition moderates the relationship between MetS and Mobility. METHOD: Adults ages 45-90 years were recruited. MetS risk factors and mobility performance (Short Physical Performance Battery (SPPB) and gait speed) were evaluated. Cognition was assessed using a comprehensive neuropsychological battery. A factor analysis of neuropsychological test scores yielded three factors: executive function, explicit memory, and semantic/contextual memory. Multivariable linear regression models were used to examine the relationship among MetS, mobility, and cognition. RESULTS: Of the 74 participants (average age 61 ± 9 years; 41% female; 69% White), 27 (36%) participants manifested MetS. Mean SPPB score was 10.9 ± 1.2 out of 12 and gait speed was 1.0 ± 0.2 m/s. There were no statistically significant differences in mobility by MetS status. However, increase in any one of the MetS risk factors was associated with decreased mobility performance after adjusting for age and gender (SPPB score: ß (SE) -.17 (0.08), p < .05; gait speed: -.03 (.01), p < .01). Further adjusting for cognitive factors (SPPB score: explicit memory .31 (.14), p = .03; executive function 0.45 (0.13), p < .01; gait speed: explicit memory 0.04 (0.02), p = .03; executive function 0.06 (0.02), p < .01) moderated the relationships between number of metabolic risk factors and mobility. CONCLUSION: The relationship between metabolic risk factors and mobility may be moderated by cognitive performance, specifically through executive function and explicit memory.

BACKGROUND: Given the evidence of the links between cognition and mobility, participation in cognitive activities may benefit neuromotor performance and mobility in older adults. AIMS: To examine the association between participation in cognitive activities and foot reaction time (RT) and gait speed in community-dwelling older adults. METHODS: The MOBILIZE Boston Study II (MBSII) re-enrolled 354 community-dwelling older adults aged ≥ 70 years from the original MBS cohort. Of these, 310 completed the performance testing and we excluded three participants who had Parkinson's disease. Cognitive Activities Scale (CAS) assessed participation in 17 cognitive activities. Simple and Choice foot RT (SRT, CRT, msec) and gait speed (m/s) were measured using a sensored GAITRite® gait mat. RESULTS: The average age of the 307 participants was 84 years; 79% were white and 65% were women. The average CAS score was 25.5 ± 11.7, indicating participation in approximately 26 activities per week on average. The average foot SRT was 245 ± 57msec and average CRT was 323 ± 85msec. Usual-paced gait speed was 0.9 ± 0.3 m/s on average. More frequent participation in cognitive activities was associated with shorter SRT (ß = - 0.759, p = 0.015) and CRT (ß = - 1.125, p = 0.013), and faster gait speed (ß = 0.003, p = 0.026), after adjusting for potential confounders. DISCUSSION: Participation in cognitively stimulating activities may be beneficial for neuromotor performance and mobility in older adults. CONCLUSIONS: Prospective and intervention studies are needed to determine whether participation in cognitive activities may prevent mobility decline over time, and thus reduce fall risk.

OBJECTIVE: To determine if poorer gait variability and gait coordination among mobility-limited older adults is related to their slower walking speed. DESIGN: Cross-sectional analysis. SETTING: University research laboratory. PARTICIPANTS: Community-dwelling adults (N=69) 68 years or older with (Short Physical Performance Battery score ≤9; n=37) and without (n=32) mobility limitations. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The variability of step length, swing time percent, and step width. Gait coordination was assessed along with the Phase Coordination Index. RESULTS: The usual pace gait speed of those without mobility limitations was faster (1.22±0.14m/s vs 0.71±0.14m/s; P<.001) and less variable in all gait characteristics (all P<.001), with the exception of step width (P=.185), than those with limitations. When those without limitations slowed their walking pace (0.71m/s±0.14), their gait coordination became poorer (P<.001), and the variability of all gait characteristics increased (all P<.001) except for step width, which decreased (P=.002). When those without mobility limitations walked at a slow pace, they had better gait coordination (P=.008) and less variable step length (P=.014) and swing time percent (P=.036). The variability of stride time (P=.260) and step width (P=.385) were not significantly different than that of their peers with limitations. CONCLUSIONS: Increased variability in some gait characteristics of mobility-limited older adults appears to be related to their slower walking speed. Gait coordination and the variability of step length and swing time percent may reflect intrinsic differences in mobility-limited older adults that are independent of walking speed.

OBJECTIVE: To explore the predictive ability of the Short Physical Performance Battery (SPPB), Late Life Function and Disability Instrument-Function component (LLFDI-function) and frailty phenotype, for falls, hospitalizations, emergency department (ED) visits, and low self-rated health (SRH) over 1 and 2 years in older adults. DESIGN: Secondary analysis of data from a longitudinal study, the Boston Rehabilitative Impairment Study of the Elderly. SETTING: Primary care. PARTICIPANTS: Adults 65 years and older at risk for disability who completed ≥1 follow-up call (N=391). INTERVENTIONS: None. MAIN OUTCOME MEASURES: We computed separate logistic regression models using the SPPB, LLFDI-function, and frailty phenotype as independent variables and falls, hospitalizations, ED visits, and SRH over 1 and 2 years as dependent variables. Receiver operating characteristic curves were constructed and the areas under the curves calculated. RESULTS: Participants had a mean age of 76.5±7.1 years. The SPPB, LLFDI-function, and frailty phenotype all predicted hospitalizations and low SRH over a 1- and 2-year timeframe (odds ratio [OR] min-max, 1.35-1.51 and 1.67-3.07, respectively). Over 2 years, the SPPB predicted ED visits (OR, 1.28), and the LLFDI-function predicted falls (OR, 1.31). The LLFDI-function predicted low SRH better than the frailty phenotype over 1 year. There were no differences between the measures for any of the other outcomes. CONCLUSIONS: The SPPB, LLFDI-function, and frailty phenotype had similar accuracy for predicting falls, hospitalizations, ED visits, and low SRH over 1 and 2 years among older primary care patients at risk for disability. As a result, when considering the optimal screening tool for older adults, the choice between a measure of function and frailty may ultimately depend on clinical preference and context.

OBJECTIVE: To investigate a proposed cognitively-mediated pathway whereby pain contributes to gait impairments by acting as a distractor in community-living older adults. DESIGN: A cross-sectional study of a population-based cohort of older adults. SETTING: Urban and suburban communities in a large metropolitan area. PARTICIPANTS: Community-living participants (N=302) 70 years and older recruited from a previous population-based cohort. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Gait parameters including gait speed, stride length, double support and swing characteristics, and variability were assessed under single- and dual-task conditions involving cognitive challenges (eg, counting backward). A joint pain questionnaire assessed pain distribution in the back and major joints. We examined pain-gait relationships using multivariable linear regression and bootstrapping mediation procedures. RESULTS: Forty-three percent of participants had pain in 2 or more musculoskeletal sites. Pain distribution was related to slower gait speed and other gait characteristics for all gait conditions. Associations persisted after adjustment for age, sex, education, body mass index, medication, and vision. Decrements in gait measures related to pain were comparable with decrements in gait related to dual-task conditions. There were no differences in dual-task cost among the pain distribution groups. Adjusted for confounders, pain-gait relationships appear mediated by selective attention. CONCLUSIONS: These findings suggest that chronic pain contributes to decrements in gait, including slower gait speed, and that it operates through a cognitively-mediated pathway. Further research is needed to understand the mechanisms via pain alters mobility and to develop interventions to improve mobility among older adults with chronic pain.

Recognizing a need for more guidance on the coronavirus disease 2019 (COVID-19) pandemic, members of the Archives of Physical Medicine and Rehabilitation Editorial Board invited several clinicians with early experience managing the disease to collaborate on a document to help guide rehabilitation clinicians in the community. This consensus document is written in a "question and answer" format and contains information on the following items: common manifestations of the disease; rehabilitation recommendations in the acute hospital setting, recommendations for inpatient rehabilitation and special considerations. These suggestions are intended for use by rehabilitation clinicians in the inpatient setting caring for patients with confirmed or suspected COVID-19. The text represents the authors' best judgment at the time it was written. However, our knowledge of COVID-19 is growing rapidly. The reader should take advantage of the most up-to-date information when making clinical decisions.

Older adults are the fastest growing segment of our population and contribute greatly to the high costs of health care. The primary concern among older adults seeking health care is maintaining or improving functional independence. This concern is the focus of both rehabilitative care and geriatric medicine; however, collaboration between these fields can be hampered by a lack of mutual understanding of the fundamental principles of the other field. We describe 3 steps that can be implemented at an organizational or individual level to bridge the fields of geriatric medicine and rehabilitation, allowing them to better serve older patients. These include (1) recognizing the interwoven concepts of multimorbidity, function, and frailty; (2) communicating with a common language; and (3) synthesizing our knowledge from both fields.

OBJECTIVES: To examine associations between mild cognitive impairment (MCI) and falls among primary care patients, and to investigate whether social engagement (SE) modifies these associations. DESIGN: Cross sectional analysis using baseline data from an observational cohort study. SETTING: Primary care. PARTICIPANTS: Community-dwelling older adults (N=430) at risk of mobility decline with a mean age of 76.6 years (range 65-96y). MAIN OUTCOME MEASURES: The number of falls in the past year was reported at the baseline interview. MCI was identified using a cutoff of 1.5 SD below the age-adjusted mean on at least 2 of the standardized cognitive performance tests. SE (eg, keeping in touch with friends and family, volunteering, participating social activities ) was assessed with the Late Life Function and Disability Instrument, and required a score above the median value 49.5 out of 100. RESULTS: MCI was present among 42% of participants and 42% reported at least 1 fall in the preceding year. Using generalized estimating equations, MCI was associated with a 77% greater rate of falls (P<.05). There was a statistically significant interaction between SE and MCI on the rate of falls (P<.01), such that at a high level of SE, MCI was not statistically associated with falls (P=.83). In participants with lower levels of SE, MCI is associated with 1.3 times greater rate of falls (P<.01). CONCLUSIONS: While MCI is associated with a greater risk for falls, higher levels of SE may play a protective role.

OBJECTIVE: To evaluate the proof of concept of an innovative model of physical therapy Rehabilitation Enhancing Aging through Connected Health (REACH) and evaluated its feasibility and effect on physical function and health care utilization. DESIGN: Quasi-experimental 12-month clinical trial. SETTING: Two outpatient rehabilitation centers. PARTICIPANTS: Community-dwelling older primary care patients with a treatment arm undergoing the intervention (n=75; mean age=77±5.9y; 54% women) and propensity matched controls derived from a longitudinal cohort study (n=430; mean age=71±7.0y; 68% women) using identical recruitment criteria (N=505). INTERVENTION: Combined outpatient and home PT augmented with a commercially available app and computer tablet. MEASUREMENTS: Primary outcomes included a feasibility questionnaire, exercise adherence, self-reported function, and the Short Physical Performance Battery (SPPB). Secondary outcomes included the rates of emergency department (ED) visits and hospitalizations. RESULTS: Among REACH participants, we observed a 9% dropout rate. After accounting for dropouts, with propensity matching, n=68 treatments and n=100 controls were analyzed. Over the 12-month study duration, 85% of participants adhered to the exercise program an average of 2 times a week and evaluated the treatment experience favorably. In comparison to controls, after 1 year of treatment and within multivariable regression models, REACH participants did not manifest a significant difference in patient reported function (group x time effect 1.67 units, P=.10) but did manifest significant differences in SPPB (group x time effect 0.69 units, P=.03) and gait speed (group x time effect .08m/s, P=.02). In comparison to controls, after 1 year, the rate of ED visits (group x time treatment rate=0.27, P<.004) were significantly reduced, but a significant reduction in hospitalizations was not observed. CONCLUSION: The REACH intervention is feasible and has proof of concept in preventing functional decline and favorably affecting health care utilization. Evaluation on a larger scale is warranted.

BACKGROUND: Chronic musculoskeletal pain is highly prevalent in the older adults, and individuals with musculoskeletal pain frequently report pain in two or more sites. AIMS: To determine the prevalence and characteristics of multisite pain in relation to other geriatric syndromes and to evaluate whether multisite pain may represent a distinct geriatric syndrome. METHODS: The MOBILIZE Boston Study is a population-based cohort study of older adults that enrolled 749 participants aged 70 and older. Persistent pain in the back and major joint areas was assessed using a joint pain questionnaire. Assessment of other geriatric syndromes included urinary incontinence, fall history, ADL disability, and frailty. A number of risk factors for geriatric syndromes were assessed. RESULTS: The prevalence of multisite pain was 40% in this population of older adults. Many participants had more than one geriatric syndrome, indicating substantial overlap in the prevalence of these conditions. Nearly half (48%) of participants with urinary incontinence or falls, 61% with ADL disability, and 49% of those with frailty also had multisite pain. Shared risk factors for established geriatric conditions were similarly distributed among the elderly population who had multisite pain. Demographic and health characteristics associated with multisite pain and other geriatric syndromes, included gender (female), depression, number of comorbid conditions, and mobility limitations. CONCLUSION: Although prior studies have explored risk factors for chronic multisite pain, these findings reveal that multisite pain, often unexplained, bears many similarities to established geriatric syndromes. Multisite pain warrants further consideration as a unique geriatric syndrome.

OBJECTIVES: To identify neuromuscular attributes associated with mobility and changes in mobility over 2 years of follow-up among patients with and without symptomatic lumbar spinal stenosis (SLSS). DESIGN: Secondary analysis of a longitudinal cohort study. SETTING: Outpatient rehabilitation center. PARTICIPANTS: Community-dwelling older adults ≥65 years with self-reported mobility limitations (N=430). SLSS was determined using self-reported symptoms of neurogenic claudication and imaging-detected lumbar spinal stenosis. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Basic and advanced mobility as measured by the Late-Life Function and Disability Instrument (LLFDI). RESULTS: Among 430 community-dwelling older adults, 54 (13%) patients met criteria for SLSS, while 246 (57%) did not. On average LLFDI basic and advanced mobility scores decreased significantly from baseline through year 2 for participants with SLSS (basic: P=.04, 95% CI 0.18, 5.21; advanced P=.03, 95% CI 0.39, 7.84). Trunk extensor muscle endurance (trunk endurance) and leg strength were associated with baseline basic mobility (R2=0.27, P<.001) while leg strength and knee flexion range of motion (ROM) were associated with baseline advanced mobility among participants with SLSS (R2=0.47, P<.001). Among participants without SLSS trunk endurance, leg strength and ankle ROM were associated with baseline basic mobility (R2=0.38, P<.001), while trunk endurance, leg strength, leg strength asymmetry, and knee flexion ROM were associated with advanced mobility (R2=0.20, P<.001). Trunk endurance and leg strength were associated with change in basic mobility (R2=0.29, P<.001), while trunk endurance and knee flexion ROM were associated with change in advanced mobility (R2=0.42, P<.001) among participants with SLSS. Among participants without SLSS trunk endurance, leg strength, knee flexion ROM, and ankle ROM were associated with change in basic mobility (R2=0.22, P<.001), while trunk endurance, leg strength, and knee flexion ROM were associated with change in advanced mobility (R2=0.36, P<.001). CONCLUSIONS: Patients with SLSS experience greater impairment in the neuromuscular attributes: trunk endurance, leg strength, leg strength asymmetry, knee flexion and extension ROM, and ankle ROM compared to patients without SLSS. Differences exist in the neuromuscular attributes associated with mobility at baseline and decline in mobility over 2 years of follow-up for patients with and without SLSS. These findings may help guide rehabilitative care approaches for patients with SLSS.

Longitudinal assessment of chronic geriatric pain is complicated by an age-associated plateau in pain severity and increase in widespread pain, calling for innovative measures such as pain quality descriptors that characterize how pain may feel. We characterized persistence of pain quality and its relation to severity, activity interference and distribution of sites, in a population-based sample of adults aged≥70 years with chronic pain (n = 398). Persistent pain quality was defined as reporting descriptors within the same category: sensory, cognitive/affective, or neuropathic at baseline and 18 months. A count variable indicated number of persistent categories. Pain quality was highly persistent. Adjusted for baseline covariates, individuals endorsing 3 persistent categories were 2-2.5x more likely to experience more widespread pain at 18 months compared to fewer persistent categories. No associations were noted in changes in pain severity or interference. A comprehensive pain assessment that includes diverse pain quality descriptors may improve individualized pain management.
