Virtual Rehabilitation and COVID-19: Varied Adoption and Satisfaction Among Patients and Providers Participating in a Multi-Site Survey Study

The COVID-19 pandemic compelled rapid healthcare adaptations including increased use of telehealth (TH) and virtual care (VC) to provide rehabilitation services. This multi-site cross-sectional survey study examined rehabilitation patients' and providers' experiences with service delivery during the COVID-19 pandemic, including the use of TH/VC. Patients and providers who received or provided rehabilitation services were recruited from 1 of 3 large, post-acute rehabilitation systems located in the Southeastern and Midwestern United States during the COVID-19 pandemic. Participants rated personal satisfaction with rehabilitation services received or rendered during the pandemic and willingness to use TH/VC in the future. Questions also addressed accessibility, ease of use, and perceived barriers to TH/VC use. The adoption and personal satisfaction of TH/VC for rehabilitation care varied between patients and providers. Patients reported higher levels of satisfaction compared to providers (P < .001). Patients who did not use TH/VC had higher satisfaction than those who did (P < .05). Patients were less willing than providers to use TH/VC (P < .001). Those who used TH/VC prior to the pandemic were more willing to use post-pandemic (P < .001). Patients reported TH/VC was useful in increasing health services accessibility yet were neutral as to the ability of TH/VC to improve outcomes. Patients and providers agreed that TH/VC was easy to learn and use. Medical providers found TH/VC more useful than therapy providers. Participants who used TH/VC during the pandemic are more willing to use the service again in the future. Understanding patient and provider preferences and perspectives is key to the continued use of TH/VC in rehabilitation care.

The Biology of Placebo and Nocebo Effects on Experimental and Chronic Pain: State of the Art

(1) Background: In recent years, placebo and nocebo effects have been extensively documented in different medical conditions, including pain. The scientific literature has provided strong evidence of how the psychosocial context accompanying the treatment administration can influence the therapeutic outcome positively (placebo effects) or negatively (nocebo effects). (2) Methods: This state-of-the-art paper aims to provide an updated overview of placebo and nocebo effects on pain. (3) Results: The most common study designs, the psychological mechanisms, and neurobiological/genetic determinants of these phenomena are discussed, focusing on the differences between positive and negative context effects on pain in experimental settings on healthy volunteers and in clinical settings on chronic pain patients. Finally, the last section describes the implications for clinical and research practice to maximize the medical and scientific routine and correctly interpret the results of research studies on placebo and nocebo effects. (4) Conclusions: While studies on healthy participants seem consistent and provide a clear picture of how the brain reacts to the context, there are no unique results of the occurrence and magnitude of placebo and nocebo effects in chronic pain patients, mainly due to the heterogeneity of pain. This opens up the need for future studies on the topic.

Resident Case Series: Blood Flow Restriction as an Adjunct to Strengthening Exercises in Two Patients with Subacromial Impingement and High Irritability

Introduction

Evidence informed management of individuals presenting with subacromial impingement syndrome (SAIS) includes strengthening exercises directed at the shoulder musculature. Patients with subacromial impingement syndrome (SAIS) can present with pain during and after completion of heavy resistance training limiting the applicability of this recommended treatment approach. Blood flow restriction (BFR) training is indicated for patients who have pain while completing heavy resistance training and may represent an important treatment modification for patients with SAIS unable to fully participate in a strengthening exercise program. The purpose of this case series is to describe the inclusion of BFR in the treatment of two patients with SAIS.

Case descriptions

Two middle aged, non-operative patients with signs and symptoms consistent with SAIS and high levels of irritability were included. Treatment over one month consisted of three commonly used exercises in the treatment of SAIS in conjunction with a standard BFR protocol: 75 reps broken up into sets of 30,15,15,15 with the BFR cuff placed over proximal humerus.

Outcomes

Immediate within session improvements beyond measurement error were observed in resting pain and pain pressure thresholds at three sites. At the end of the course of treatment, clinically meaningful improvements were observed in patient reported outcomes including the PENN Score, ASES score, and the patient-specific functional scale. Clinically meaningful improvements and change beyond measurement error were also observed in range of motion and strength which (assessed via a handheld dynamometer).

Discussion

The incorporation of low load resistance training with BFR may be a useful adjunct for treating patients with SAIS to promote exercise-induced hypoalgesia, decrease pain, and increase function in the upper extremity.

Age Differences in Multimodal Quantitative Sensory Testing and Associations With Brain Volume

BACKGROUND AND OBJECTIVES

Somatosensory function is critical for successful aging. Prior studies have shown declines in somatosensory function with age; however, this may be affected by testing site, modality, and biobehavioral factors. While somatosensory function declines are associated with peripheral nervous system degradation, little is known regarding correlates with the central nervous system and brain structure in particular. The objectives of this study were to examine age-related declines in somatosensory function using innocuous and noxious stimuli, across 2 anatomical testing sites, with considerations for affect and cognitive function, and associations between somatosensory function and brain structure in older adults.

RESEARCH DESIGN AND METHODS

A cross-sectional analysis included 84 "younger" (n = 22, age range: 19-24 years) and "older" (n = 62, age range: 60-94 years) healthy adults who participated in the Neuromodulatory Examination of Pain and Mobility Across the Lifespan study. Participants were assessed on measures of somatosensory function (quantitative sensory testing), at 2 sites (metatarsal and thenar) using standardized procedures, and completed cognitive and psychological function measures and structural magnetic resonance imaging.

RESULTS

Significant age × test site interaction effects were observed for warmth detection (p = .018,η p 2 = 0.10) and heat pain thresholds (p = .014,η p 2 = 0.12). Main age effects were observed for mechanical, vibratory, cold, and warmth detection thresholds (ps < .05), with older adults displaying a loss of sensory function. Significant associations between somatosensory function and brain gray matter structure emerged in the right occipital region, the right temporal region, and the left pericallosum.

DISCUSSION AND IMPLICATIONS

Our findings indicate healthy older adults display alterations in sensory responses to innocuous and noxious stimuli compared to younger adults and, furthermore, these alterations are uniquely affected by anatomical site. These findings suggest a nonuniform decline in somatosensation in older adults, which may represent peripheral and central nervous system alterations part of aging processes.

Patient-centered outcomes: Domain importance predicts health care use following physical therapy

INTRODUCTION

Identifying patients with musculoskeletal pain who are at risk for additional health care use is important for improving the value of physical therapists' services. We previously identified three subgroups based on the importance attached by patients to improvements in outcome domains including a (1) Pain and Function Outcomes Important subgroup; (2) Pain Important subgroup; and (3) Multiple Outcome Domains Important subgroup.

OBJECTIVE

The primary aim was to determine whether subgroups based on patient-determined outcomes of importance predicted any additional pain-related health care use after an episode of physical therapy. A secondary aim was to determine if subgroup membership predicted use of specific services.

DESIGN

Secondary analysis of a longitudinal cohort.

SETTING

Ambulatory outpatient physical therapy clinics.

PATIENTS

Two hundred forty-six patients seeking physical therapy recruited from the Optimal Screening for Prediction of Referral and Outcome (OSPRO) cohort study.

INTERVENTIONS

Patients completed a demographic and health history questionnaire, numeric pain rating scale, region-specific disability measure, and Charlson Comorbidity Index. Subgroup membership was determined based on responses to the Patient Centered Outcome Questionnaire. At 1 year, patients reported use of health care since discharge from physical therapy. Separate logistic regression models determined whether subgroup membership predicted additional health care use.

RESULTS

Compared to the Pain and Function Outcomes Important subgroup, the Pain Important subgroup had higher adjusted odds (95% confidence interval [CI]) for the primary outcome of any additional health care use (adjusted odds ratio [aOR] 2.47, 95% CI 1.01-6.00) and secondary outcomes of opioid use (aOR 9.45, 95% CI 2.87-31.17), injection (aOR 4.09, 95% CI 1.25-13.41), and surgery (aOR 5.10, 95% CI 1.15-22.67). There were no significant differences in health care utilization between the Pain and Function Outcomes Important and Multiple Outcome Domains Important subgroups.

CONCLUSION

In this cohort, patients with a singular focus on pain improvements were at higher risk for additional health care, including opioid use, injection, and surgery. These findings are exploratory and need to be confirmed in other cohorts.

Can Patient Expectations Modulate the Short-Term Effects of Dry Needling on Sensitivity Outcomes in Patients with Mechanical Neck Pain? A Randomised Clinical Trial

OBJECTIVE

Dry needling is commonly used for the management of musculoskeletal pain patients. However, the effects of patient expectations are uncertain. Our aim was to determine the effect of patient expectations on short-term clinical outcomes after the application of a single session of dry needling in individuals with neck pain.

METHODS

We conducted a randomized, placebo controlled, clinical trial including fifty patients with mechanical neck pain. Participants received a single session of dry needling or sham needling in a blinded design. Predicted patient expectation was categorized as positive, neutral, or negative. Outcomes including neck pain intensity (visual analogue scale, 0-100), pressure pain thresholds (PPTs) and self-perceived improvement (Global Rating of Change [GROC], -7 to + 7) were assessed at baseline, one day (immediately post), and 7 days (one week) after the intervention by a blinded assessor. Repeated measures ANCOVAs were conducted to assess the effects of real/sham needling adjusted by patient expectations.

RESULTS

Individuals receiving dry needling exhibited better outcomes than those receiving sham needling immediately and one-week after (all, P < 0.01). No general effects of patient expectations, either related to pain recovery or function improvement, were observed on the clinical outcomes, except for a small association of questionable clinical relevance between positive expectations and localized PPTs in the dry needling group.

CONCLUSION

This study did not find a significant effect of predicted patient expectations on the short-term effects of dry needling on pain intensity and PPTs in people with mechanical neck pain.

Importance of Outcome Domain for Patients With Musculoskeletal Pain: Characterizing Subgroups and Their Response to Treatment

BACKGROUND

Patient-centered care models allow for the ability to tailor treatment to outcomes of importance to patients.

OBJECTIVE

The purposes of this study were to (1) define patient subgroups based on outcomes of importance; (2) determine whether patient subgroups based on outcomes of importance differed in demographic, clinical, and psychological measures; and (3) determine whether outcome domain subgroups differed in treatment responses.

DESIGN

This was a prospective, longitudinal observational study.

METHODS

This was a secondary analysis of the Optimal Screening for Prediction of Referral and Outcome study. Patients in the development phase completed the Patient Centered Outcome Questionnaire (PCOQ) and questionnaires related to negative mood, fear avoidance, and positive coping, as well as region-specific questionnaires. Patients in the validation cohort completed the PCOQ, measures of treatment satisfaction and region-specific questionnaires at 4 weeks, 6 months, and 1 year. A hierarchical agglomerative cluster analysis identified profiles based on importance outcomes as determined by the PCOQ. Analysis of variance and chi-squared assessed baseline subgroup differences in demographics, psychological factors, and clinical outcomes. Repeated-measure analysis of variance considered subgroup differences in outcomes longitudinally.

RESULTS

Cluster analysis identified 3 subgroups: (1) "Multiple Outcome Domains Important" subgroup characterized by high importance attached to improvement in all domains, (2) "Pain and Function Outcomes Important" subgroup characterized by high importance attached to improvement in pain and interference, and (3) "Pain Important" subgroup characterized by greatest importance attached to improvement in pain.

LIMITATIONS

Our sample included patients from outpatient physical therapy and may not be representative of patients in other settings.

CONCLUSION

Patients can be characterized by the importance attached to improvement in outcome domains. The identified subgroups differed in baseline measures as well as response to treatment.

Kinesiophobia and Its Association With Health-Related Quality of Life Across Injury Locations

OBJECTIVE

To compare baseline kinesiophobia levels and their association with health-related quality of life across injury locations.

DESIGN

Retrospective cross-sectional study.

SETTING

Single, large outpatient physical therapy clinic within an academic medical center.

PARTICIPANTS

Patients (N=1233) who underwent an initial evaluation for a diagnosis related to musculoskeletal pain and completed the 11-item version of the Tampa Scale for Kinesiophobia (TSK-11) and the Medical Outcomes Study 8-Item Short-Form Health Survey (SF-8) questionnaires within 7 days of their first visit were eligible for inclusion. Three hundred eighty patients were excluded because of missing data or because they were younger than 18 years. A total of 853 patients (mean age, 43.55y; range, 18-94y) were included.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Comparison of baseline kinesiophobia levels and their association with health-related quality of life across injury locations in an outpatient physical therapy setting.

RESULTS

Separate analysis of variance models compared TSK-11 scores based on involved body region, and Pearson correlation coefficients were used to examine the association between TSK-11 scores and the SF-8 subscales at each body region. TSK-11 scores did not differ by body region (range, 23.9-26.1). Weak to moderate negative correlations existed between kinesiophobia and the SF-8 subscales.

CONCLUSIONS

Kinesiophobia levels appear elevated and negatively associated with health-related quality of life at initial physical therapy evaluation regardless of injury location. These findings suggest that physical therapists in outpatient orthopedic settings should implement routine kinesiophobia assessment and provide stratified care based on kinesiophobia levels across musculoskeletal conditions.
