Psychologically Informed Physical Therapy Management of Chronic Musculoskeletal Pain in Culturally Diverse Populations: An Intervention Logic Model.

Culturally and linguistically diverse (CALD) individuals are underrepresented in pain research, including studies of psychologically informed physical therapy (PIPT) for musculoskeletal pain. This perspective describes a conceptual framework for PIPT management of chronic musculoskeletal pain that identifies essential elements which can be culturally tailored to meet the needs of different CALD populations. Essential interventions, determinants of behavior change, and clinical outcomes were identified from studies of existing PIPT interventions for chronic pain. PIPT approaches shared the following essential interventions: (1) cognitive skill training, (2) general aerobic activity, (3) impairment-based therapeutic exercises, and (4) graded functional movement training. An intervention logic model was developed to conceptualize how these interventions might promote active coping behaviors and greater engagement in physical activity, therapeutic exercise, and functional mobility. The model included physical and cognitive-emotional processes that may contribute to behavioral changes which ultimately reduce pain-related disability. To illustrate cultural tailoring of model constructs, we describe how intervention delivery and assessments were customized for Latino persons with chronic spine pain at a health center located near the United States (US)-Mexico border. A literature review of sociocultural influences on the pain experience of Latino persons was conducted, and essential elements of the model were operationalized to ensure that therapeutic goals, language, content, and processes were compatible with Latino cultural beliefs, values, and behaviors. Future research using the proposed model to adapt and test PIPT interventions for other CALD populations may help identify shared and divergent mechanisms of treatment response for culturally tailored pain management programs. PERSPECTIVE: A novel conceptual framework may help inform cultural tailoring of psychologically informed physical therapy management approaches for chronic musculoskeletal pain by maintaining fidelity to essential treatment elements while also leveraging the unique sociocultural context of different culturally and linguistically diverse communities to improve health outcomes.

Identifying Clinical Phenotypes in People Who Are Hispanic/Latino With Chronic Low Back Pain: Use of Sensor-Based Measures of Posture and Movement, Pain, and Psychological Factors.

OBJECTIVE: The aim of this study was to identify clinical phenotypes using sensor-based measures of posture and movement, pain behavior, and psychological factors in Hispanic/Latino people with chronic low back pain (CLBP). METHODS: Baseline measures from an ongoing clinical trial were analyzed for 81 Hispanic/Latino people with CLBP. Low back posture and movement were measured using commercial sensors during in-person testing and 8 hours of ecological monitoring. Magnitude, frequency, and duration of lumbar movements, sitting and standing postures were measured. Movement-evoked pain was assessed during in-person movement testing. Psychological measures included the Pain Catastrophizing Scale and the Fear Avoidance Beliefs Questionnaire. Random forest analysis was conducted to generate 2 groups and identify important variables that distinguish groups. Group differences in demographics, pain, psychological, and posture and movement variables were examined using t-tests and chi-square analyses. RESULTS: Two subgroups of Hispanic/Latino people with CLBP were identified with minimal error (7.4% misclassification ["out-of-bag" error]). Ecological posture and movement measures best distinguished groups, although most movement-evoked pain and psychological measures did not. Group 1 had greater height and weight, lower movement frequency, more time in sitting, and less time in standing. Group 2 had a greater proportion of women than men, longer low back pain duration, higher movement frequency, more time in standing, and less time in sitting. CONCLUSION: Two distinct clinical phenotypes of Hispanic/Latino people with CLBP were identified. One group was distinguished by greater height and weight and more sedentary posture and movement behavior; the second group had more women, longer duration of low back pain, higher lumbar spine movement frequency, and longer duration of standing postures. IMPACT: Ecological measures of posture and movement are important for identifying 2 clinical phenotypes in Hispanic/Latino people with CLBP and may provide a basis for a more personalized plan of care. LAY SUMMARY: Wearable sensors were used to measure low back posture and movement in Hispanic/Latino people with chronic low back pain. These posture and movement measures helped to identify 2 different clinical subgroups that will give physical therapists more information to better personalize treatment for chronic low back pain in Hispanic/Latino patients.

Use of Intervention Mapping to Adapt a Psychologically Informed Physical Therapy Telerehabilitation Intervention for Latino Persons with Chronic Spine Pain.

The need for culturally tailored pain care is well recognized yet few studies report how existing interventions can be adapted to the needs of culturally and linguistically diverse (CALD) populations. This report describes a formative mixed methods approach using Intervention Mapping-Adapt (IM-Adapt) and the expanded Framework for Reporting Adaptations and Modifications to Evidence based interventions (FRAME) to adapt and report modifications of an existing physical therapy intervention for Latino persons with chronic spine pain in Federally Qualified Health clinics in the southwestern United States (US). Mixed methods included literature reviews, patient surveys, an Adaptation Advisory Panel, and sequential case series with semi-structured interviews. Six steps of IM-Adapt guided the adaptation process and adaptations were prospectively documented with FRAME. A needs assessment revealed an absence of culturally tailored physical therapy interventions for Latino persons with chronic spine pain in the US. An intervention logic model and review of the sociocultural context guided selection of essential interventions, determinants of behavior change, and outcomes. An existing Cognitive Behavioral based Physical Therapy (CBPT) telerehabilitation intervention was selected for adaptation based on accessibility and strong congruency with the logic model. An Adaptation Advisory Panel planned and evaluated iterative adaptations of the CBPT intervention content, activities, delivery, materials, and design. The adapted Goal Oriented Activity for Latino persons with Spine pain (GOALS/Metas) intervention aimed to reduce pain intensity and disability through patient-centered goal setting in physical and cognitive treatment domains. Sequential case series supported feasibility and acceptability of the adapted intervention in the target population. PERSPECTIVE: We describe the systematic adaptation and reporting of an evidence-based physical therapy intervention for culturally and linguistically diverse populations. Greater rigor and transparency in adapting evidence-based interventions using tools such as IM-Adapt and FRAME in future studies will accelerate efforts to reduce ethnic and racial disparities in pain rehabilitation.

Protocol for a Parallel Group Randomized Clinical Trial Comparing a Culturally Adapted Cognitive Behavioral Telerehabilitation Intervention to Usual Physical Therapy for Latino Patients With Chronic Spine Pain.

OBJECTIVE: Disparities exist in health care access, diagnosis, and treatment of chronic pain in Latino populations and other minority populations. Cognitive behavioral-based physical therapy (CBPT) interventions have been shown to be effective in predominantly non-Hispanic white populations with chronic spine pain. However, there is a need for culturally adapted CBPT interventions that focus on the conservative management of chronic spine pain. The primary purpose of the study described in this protocol is to test the efficacy of an adapted cognitive behavioral-based hybrid telerehabilitation intervention for Latino patients with chronic spine pain. METHODS: A single-blind, 2-arm parallel group, superiority randomized clinical trial is planned to compare an adapted CBPT intervention to Usual Care physical therapy. Goal Oriented Activity for Latinos with chronic Spine pain (GOALS/Metas) is an 8-week hybrid telerehabilitation intervention that integrates guideline-based physical therapy and pain management interventions using cognitive behavioral approaches and has been adapted for Latino patients with chronic spine pain. Usual Care physical therapy will be administered based on institutional standards at the referring health center. Outcome measures will be evaluated preintervention and at 1-week, 3-months, and 6-months postintervention. The primary outcome is pain-related disability 1-week postintervention using the Brief Pain Inventory Pain Interference subscale. Secondary outcome measures include behavioral measures of functional activity, social participation, physical activity, and sleep. Determinants of treatment effect, including pain-related psychological measures, posture and movement, self-efficacy, treatment expectancy, and therapeutic alliance, will be included in the secondary moderation and mediation analyses. IMPACT: This clinical trial will provide information on the extent to which an adapted CBPT hybrid telerehabilitation intervention is effective in reducing pain-related disability for Latino patients with chronic spine pain. This information will be useful for clinicians to integrate in their practice, given the growing population of Latino patients who experience disparities in health care management of chronic pain.
