Predictive factors of adherence to frequency and duration components in home exercise programs for neck and low back pain: an observational study

BackgroundEvidence suggests that to facilitate physical activity sedentary people may adhere to one component of exercise prescriptions (intensity, duration or frequency) without adhering to other components. Some experts have provided evidence for determinants of adherence to different components among healthy people. However, our understanding remains scarce in this area for patients with neck or low back pain. The aims of this study are to determine whether patients with neck or low back pain have different rates of adherence to exercise components of frequency per week and duration per session when prescribed with a home exercise program, and to identify if adherence to both exercise components have distinct predictive factors.MethodsA cohort of one hundred eighty-four patients with chronic neck or low back pain who attended physiotherapy in eight primary care centers were studied prospectively one month after intervention. The study had three measurement periods: at baseline (measuring characteristics of patients and pain), at the end of physiotherapy intervention (measuring characteristics of the home exercise program) and a month later (measuring professional behaviors during clinical encounters, environmental factors and self-efficacy, and adherence behavior).ResultsAdherence to duration per session (70.9% ± 7.1) was more probable than adherence to frequency per week (60.7% ± 7.0). Self-efficacy was a relevant factor for both exercise components (p < 0.05). The total number of exercises prescribed was predictive of frequency adherence (p < 0.05). Professional behaviors have a distinct influence on exercise components. Frequency adherence is more probable if patients received clarification of their doubts (adjusted OR: 4.1; p < 0.05), and duration adherence is more probable if they are supervised during the learning of exercises (adjusted OR: 3.3; p < 0.05).ConclusionWe have shown in a clinic-based study that adherence to exercise prescription frequency and duration components have distinct levels and predictive factors. We recommend additional study, and advise that differential attention be given in clinical practice to each exercise component for improving adherence.

Self-Management of Chronic Neck and Low Back Pain and Relevance of Information Provided During Clinical Encounters: An Observational Study

UNLABELLED Escolar-Reina P, Medina-Mirapeix F, Gascón-Cánovas JJ, Montilla-Herrador J, Valera-Garrido JF, Collins SM. Self-management of chronic neck and low back pain and relevance of information provided during clinical encounters: an observational study. OBJECTIVE To assess the relative influence of information provided during physical therapy on a patients adherence to self-management strategies in relation to other predictors of adherence (patient and pain characteristics, use of self-management strategies before intervention). DESIGN A longitudinal observational study of the relationship between the information provided during physical therapy and adherence to self-management strategies. SETTING Data came from a clinical-based population in 8 primary health care centers. PARTICIPANTS Patients (N=184) with chronic neck or low back pain (77% under the age of 59y) were surveyed at the beginning and 1 month after completion of physical therapy. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Specific and overall adherence to 2 types of strategies: (1) nonpharmacologic pain management strategies, and (2) neck/back care in activities of daily life. RESULTS Adherence to strategies of nonpharmacologic self-management of pain was more probable when patients received information explaining the effectiveness of the self-management strategies (adjusted odds ratio [AOR]=10.1; P<.05) and information about their illness (AOR=3.4; P<.05) during clinical encounters. Information provided by the physical therapist did not have any influence on the adherence to neck/back care in activity of daily life (P>.05). CONCLUSIONS Information provided during clinical encounters is associated with adherence to different kinds of self-management strategies. While further study is required, it is suggested that more attention be given to clinical practice strategies for improving adherence to self-management of chronic pain.

Mobility Activities Measurement for Outpatient Rehabilitation Settings

OBJECTIVE To investigate the factor structure and scale properties of items underlying the mobility activities subdomains of the International Classification of Functioning, Disability and Health (ICF). DESIGN A cross-sectional self-report-based psychometric study. SETTING Outpatient rehabilitation settings (N=3) in 3 urban areas of Spain. PARTICIPANTS Convenience sample of 615 patients with musculoskeletal conditions (mean age, 38.1y) participating in an active physiotherapy program. INTERVENTIONS Not applicable. MAIN OUTCOMES MEASURES A 22-item Mobility Activities Measure by using a self-report questionnaire that assessed whether patients had limitations on daily activities across major ICF categories of mobility subdomains. Factor analysis, tests of item scaling, internal consistency reliability analysis, Rasch item response theory modeling, and modified parallel analysis were used. RESULTS Initial exploratory factor analysis results for each ICF subdomain produced a total of 5 distinct and interpretable factors or dimensions: changing and maintaining body position involving sitting and/or lying; changing and maintaining body position involving standing up; carrying, moving, and handling objects using the hand and shoulder; carrying, moving, and handling objects using the hand and/or forearm; and walking and moving. Dimensionality of these 5 factors was verified by using confirmatory factor analyses and scaling assumptions were met for each dimension. Rasch scaling and modified parallel analysis supported the unidimensionality. CONCLUSIONS The Mobility Activities Measure is a promising new self-report measure of mobility activities as defined by the ICF. Information about Mobility Activities Measure items and dimensions from this study will be useful in the future operationalization and implementation of ICF.

RELIABILITY AND VALIDITY OF PATIENT REPORTS FOR PHYSICAL THERAPY QUALITY ASSESSMENT: AN EMPIRICAL ANALYSIS REGARDING THE USE OF EXERCISES FOR NECK PAIN IN SPAIN

OBJECTIVE To determine usefulness and reliability of patient reports as a data source on the use of exercises for neck pain in primary healthcare. DESIGN Survey research. SUBJECTS A total of 176 patients with mechanical neck pain, surveyed about their physical therapy experience. METHOD A questionnaire was constructed on the selection of exercises, instructions for carrying them out and follow-up provided by the physical therapist. The same items reported by the surveyed patients were also reviewed in the physical therapy record. We analysed the reliability and validity of the questionnaire, and used the valid information from the survey to estimate a total of 8 indicators on the quality of care provided. RESULTS Sensitivity of the items was high (>75%), suggesting that most of the recorded information could be provided by patients, and specificity was quite low, suggesting that they also provide relevant information that was not recorded. These results, particularly low specificity, were not homogeneous among items. Estimates for the indicators demonstrate room for improvement. CONCLUSION Patient reports could be useful as a complement to other sources of information for physical therapy quality assessment, and they can be reliable and valid substitutes for recorded data about specific aspects of the care provided.

Rates and predictors of depression status among caregivers of patients with COPD hospitalized for acute exacerbations: a prospective study

Background Hospitalization is common for acute exacerbation of COPD, but little is known about its impact on the mental health of caregivers. Objective The aim of this study was to determine the rates and predictors of depressive symptoms in caregivers at the time of hospitalization for acute exacerbation of COPD and to identify the probability and predictors of subsequent changes in depressive status 3 months after discharge. Materials and methods This was a prospective study. Depression symptoms were measured in 87 caregivers of patients hospitalized for exacerbation at hospitalization and 3 months after discharge. We measured factors from four domains: context of care, caregiving demands, caregiver resources, and patient characteristics. Univariate and multivariate multiple logistic regressions were used to determine the predictors of depression at hospitalization and subsequent changes at 3 months. Results A total of 45 caregivers reported depression at the time of hospitalization. After multiple adjustments, spousal relationship, dyspnea, and severe airflow limitation were the strongest independent predictors of depression at hospitalization. Of these 45 caregivers, 40% had a remission of their depression 3 months after discharge. In contrast, 16.7% of caregivers who were not depressive at hospitalization became depressive at 3 months. Caregivers caring >20 hours per week for patients with dependencies had decreased odds of remission, and patients having dependencies after discharge increased the odds of caregivers becoming depressed. Conclusion Depressive symptoms are common among caregivers when patients are hospitalized for exacerbation of COPD. Although illness factors are determinants of depression at hospitalization, patient dependence determines fluctuations in the depressive status of caregivers.

Mobility limitations related to reduced pulmonary function among aging people with chronic obstructive pulmonary disease

Background Chronic obstructive pulmonary disease (COPD) is a major cause of disability. We aimed to analyse the impact of reduced pulmonary function on non-respiratory impairments and mobility activity limitations in an elderly population with COPD and to elucidate which specific limitations on mobility are related to reduced pulmonary function Methods Cross-sectional study of 110 patients with COPD, recruited from public and university hospital. The effect of impaired pulmonary function on the risk of non-respiratory impairments and mobility limitations was analysed using validated measures, including: the 6-Minute Walk Test (6MWT), skeletal muscle strength, the Short Physical Performance Battery (SPPB), and self-reported mobility questionnaire. Multivariate analysis was used to control for confounders such as age, sex, height, education, and cigarette smoking. Results Greater impairment of pulmonary function was associated with less distance walked during the 6MWT, poorer SPPB scores, and greater risk of self-reported mobility limitations (p<0.05). Lower forced expiratory volume in 1 s was also associated with a greater risk of limitations in carrying items under 10 pounds (4.54 kg), walking alone up and down a flight of stairs, and walking two or three neighbourhood blocks. There was no clear statistical relationship between pulmonary function impairment and skeletal muscle strength. Conclusions Impaired pulmonary function was associated with the 6MWT score and limitations on performance-based and self-reported mobility activities, but not with skeletal muscle strength among elderly COPD patients.

Patterns and predictors of exhaustion episodes in patients with stable COPD: A longitudinal study

Exhaustion is the perception of low energy. Little is known about how exhaustion persists, remits or reappears over time in patients with chronic obstructive pulmonary disease (COPD) or how to predict these events. We determined the likelihood of transitions between states of exhaustion and no exhaustion among patients with stable COPD followed up for 2 years. We investigated combinations of potential factors for their abilities to predict new‐onset exhaustion episodes.

Sensitivity to change of mobility measures in musculoskeletal conditions on lower extremities in outpatient rehabilitation settings

Abstract Study design: Prospective longitudinal study. Objective: To examine the sensitivity of the Mobility Activities Measure for lower extremities and to compare it to the sensitivity of the Physical Functioning Scale (PF-10) and the Patient-Specific Functional Scale (PSFS) at week 4 and week 8 post-hospitalization in outpatient rehabilitation settings. Background: Mobility Activities Measure is a set of short mobility measures to track outpatient rehabilitation progress: its scales have shown good properties but its sensitivity to change has not been reported. Methods: Patients with musculoskeletal conditions were recruited at admission in three outpatient rehabilitation settings in Spain. Data were collected at admission, week 4 and week 8 from an initial sample of 236 patients (mean age ± SD = 36.7 ± 11.1). Main outcome measures: Mobility Activities Measure scales for lower extremity; PF-10; and PSFS. Results: All the Mobility Activities Measure scales were sensitive to both positive and negative changes (the Standardized Response Means (SRMs) ranged between 1.05 and 1.53 at week 4, and between 0.63 and 1.47 at week 8). The summary measure encompassing the three Mobility Activities Measure scales detected a higher proportion of participants who had improved beyond the minimal detectable change (MDC) than detected by the PSFS and the PF-10 both at week 4 (86.64% vs. 69.81% and 42.23%, respectively) and week 8 (71.14% vs. 55.65% and 60.81%, respectively). Conclusions: The three Mobility Activities Measure scales assessing the lower extremity can be used across outpatient rehabilitation settings to provide consistent and sensitive measures of changes in patients’ mobility. Implications for rehabilitation All the scales of the Mobility Activities Measure for the lower extremity were sensitive to both positive and negative change across the follow-up periods. Overall, the summary measure encompassing the three Mobility Activities Measure scales for the lower extremity appeared more sensitive to positive changes than the Physical Functioning Scale, especially during the first four weeks of treatment. The summary measure also detected a higher percentage of participants with positive change that exceeded the minimal detectable change than the Patient-Specific Functional Scale and the Physical Functioning Scale at the first follow-up period. By demonstrating their consistency and sensitivity to change, the three Mobility Activities Measures scales can now be considered in order to track patients’ functional progress. Mobility Activities Measure can be therefore used in patients with musculoskeletal conditions across outpatient rehabilitation settings to provide estimates of change in mobility activities focusing on the lower extremity.

Determinants of each domain of the Short Physical Performance Battery in COPD

Background The Short Physical Performance Battery (SPPB) is an assessment tool with good prognostic value in COPD. It includes the following: standing balance, 4 m gait speed test (4MGS), and the timed five-repetition sit-to-stand test (5STS). The specific differences in determinants between these three tasks have not been adequately characterized in COPD patients. We aimed to identify health-related, functional, and psychological determinants of each SPPB test. Methods We conducted a cross-sectional analysis of 137 patients with stable COPD. Patients performed the SPPB, quadriceps muscle strength (QMS), exercise tolerance test (6-min walk test [6MWT]), and pulmonary function; and health-related and psychological factors, physical activity, the COPD assessment test (CAT), body mass index, age, and depression were assessed. Results Separate multivariable regression models predicting the 4MGS, 5STS, and balance test results described 31%, 39.1%, and 12.1% of the variance for each test, respectively. QMS was negatively associated with all three tests. The 6MWT was negatively associated with the 4MGS and 5STS. Depression and age were positively associated with 4MGS scores, whereas CAT and age were positively associated with 5STS scores. Conclusion The three SPPB tests did not provide equivalent information regarding a COPD patient’s status. The 5STS was associated with health status factors, while the 4MGS was associated with psychological factors.
