Preoperative and postoperative psychologically informed physical therapy: A systematic review of randomized trials among patients with degenerative spine, hip, and knee conditions

Effectiveness of psychological interventions delivered by physiotherapists in the management of neck pain: a systematic review with meta-analysis

Physiotherapists are increasingly using psychological treatments for musculoskeletal conditions. We assessed the effects of physiotherapist-delivered psychological interventions on pain, disability, and quality of life in neck pain. We evaluated quality of intervention reporting. We searched databases for randomized controlled trials (RCTs) comprising individuals with acute or chronic whiplash-associated disorder (WAD) or nontraumatic neck pain (NTNP), comparing physiotherapist-delivered psychological interventions to standard care or no treatment. Data were extracted regarding study characteristics and outcomes. Standardised mean difference (SMD) was calculated by random-effects meta-analysis. We evaluated certainty of evidence using Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) and intervention reporting using TIDieR. Fourteen RCTs (18 articles-4 detail additional outcome/follow-up data) were included comprising 2028 patients, examining acute WAD (n = 4), subacute/mixed NTNP (n = 3), chronic WAD (n = 2), and chronic NTNP (n = 5). Treatment effects on pain favoured psychological interventions in chronic NTNP at short-term (SMD -0.40 [95% CI -0.73, -0.07]), medium-term (SMD -0.29 [95% CI -0.57, 0.00]), and long-term (SMD -0.32 [95% CI -0.60, -0.05]) follow-up. For disability, effects favoured psychological interventions in acute WAD at short-term follow-up (SMD -0.39 [95% CI -0.72, -0.07]) and chronic NTNP at short-term (SMD -0.53 [95% CI -0.91, -0.15]), medium-term (SMD -0.49 [95% CI -0.77, -0.21]), and long-term (SMD -0.60 [95% CI -0.94, -0.26]) follow-up. GRADE ratings were typically moderate, and intervention reporting often lacked provision of trial materials and procedural descriptions. Psychological interventions delivered by physiotherapists were more effective than standard physiotherapy for chronic NTNP (small-to-medium effects) and, in the short term, acute WAD.

Cognitive-Behavioral-Based Physical Therapy for Improving Recovery After Traumatic Orthopaedic Lower Extremity Injury (CBPT-Trauma)

SUMMARY

Physical and psychological impairment resulting from traumatic injuries is often significant and affects employment and functional independence. Extremity trauma has been shown to negatively affect long-term self-reported physical function, the ability to work, and participation in recreational activities and contributes to increased rates of anxiety and/or depression. High pain levels early in the recovery process and psychosocial factors play a prominent role in recovery after traumatic lower extremity injury. Cognitive-behavioral therapy pain programs have been shown to mitigate these effects. However, patient access issues related to financial and transportation constraints and the competing demands of treatment focused on the physical sequelae of traumatic injury limit patient participation in this treatment modality. This article describes a telephone-delivered cognitive-behavioral-based physical therapy (CBPT-Trauma) program and design of a multicenter trial to determine its effectiveness after lower extremity trauma. Three hundred twenty-five patients from 7 Level 1 trauma centers were randomized to CBPT-Trauma or an education program after hospital discharge. The primary hypothesis is that compared with patients who receive an education program, patients who receive the CBPT-Trauma program will have improved physical function, pain, and physical and mental health at 12 months after hospital discharge.

Role of psychosocial factors on the effect of physical activity on physical function in patients after lumbar spine surgery

Background

The purpose of this study was to investigate the longitudinal postoperative relationship between physical activity, psychosocial factors, and physical function in patients undergoing lumbar spine surgery.

Methods

We enrolled 248 participants undergoing surgery for a degenerative lumbar spine condition. Physical activity was measured using a triaxial accelerometer (Actigraph GT3X) at 6-weeks (6wk), 6-months (6M), 12-months (12M) and 24-months (24M) following spine surgery. Physical function (computerized adaptive test domain version of Patient-Reported Outcomes Measurement Information System) and psychosocial factors (pain self-efficacy, depression and fear of movement) were assessed at preoperative visit and 6wk, 6M, 12M and 24M after surgery. Structural equation modeling (SEM) techniques were utilized to analyze data, and results are represented as standardized regression weights (SRW). Overall SRW were computed across five imputed datasets to account for missing data. The mediation effect of each psychosocial factor on the effect of physical activity on physical function were computed [(SRW for effect of activity on psychosocial factor X SRW for effect of psychosocial factor on function) ÷ SRW for effect of activity on function]. Each SEM model was tested for model fit by assessing established fit indexes.

Results

The overall effect of steps per day on physical function (SRW ranged from 0.08 to 0.19, p<0.05) was stronger compared to the overall effect of physical function on steps per day (SRW ranged from non-existent to 0.14, p<0.01 to 0.3). The effect of steps per day on physical function and function on steps per day remained consistent after accounting for psychosocial factors in each of the mediation models. Depression and fear of movement at 6M mediated 3.4% and 5.4% of the effect of steps per day at 6wk on physical function at 12M, respectively. Pain self-efficacy was not a statistically significant mediator.

Conclusions

The findings of this study suggest that the relationship between physical activity and physical function is stronger than the relationship of function to activity. However, future research is needed to examine whether promoting physical activity during the early postoperative period may result in improvement of long-term physical function. Since depression and fear of movement had a very small mediating effect, additional work is needed to investigate other potential mediating factors such as pain catastrophizing, resilience and exercise self-efficacy.

Psychosocial strategies for physiotherapy: A qualitative examination of physiotherapists' reported training preferences

Physiotherapists report using a range of psychosocial strategies in their practice, yet, barriers to implementation include lack of time, limited knowledge, and minimal training. This research aimed to establish what training physiotherapists have had with regards to psychosocial strategies, why they think they would benefit from more training, what training they want, and delivery preferences. Content analysis of answers to four open-ended, online survey questions collected from Australian physiotherapists (N = 208) was conducted. Physiotherapists reported having minimal training specific to psychosocial strategies. Physiotherapists reported wanting training in assessment and management of psychosocial issues, and practical application of specific psychosocial strategies. Didactic and interactive training delivered by experts who understand the psychosocial needs of their patients, and the constraints of physiotherapy practice was preferred. These findings suggest that training in psychosocial strategies at the undergraduate level and continued professional development are necessary. Specifically, training in the assessment and management of psychosocial factors, and in referral processes is warranted, and should be applicable and appropriate for rehabilitation settings. Training should be both didactic and interactive as outlined in the proposed framework.

Psychologically informed physical therapy for musculoskeletal pain: current approaches, implications, and future directions from recent randomized trials

Supplemental Digital Content is Available in the Text.

Randomized trials have examined the efficacy of psychologically informed physical therapy methods including graded activity or graded exposure, cognitive-behavioral-based physical therapy, acceptance and commitment-based physical therapy, and internet-based psychological programs compared to traditional physical therapy approaches for musculoskeletal pain. Summary findings suggest that psychologically informed physical therapy is a promising care model; however, more convincing evidence is needed to support widespread adoption, especially in light of clinician training demands.

Psychologically informed physical therapy (PIPT) blends psychological strategies within a physical therapist's treatment approach for the prevention and management of chronic musculoskeletal pain. Several randomized trials have been conducted examining the efficacy of PIPT compared to standard physical therapy on important patient-reported outcomes of disability, physical function, and pain. In this review, we examine recent trials published since 2012 to describe current PIPT methods, discuss implications from findings, and offer future directions. Twenty-two studies, representing 18 trials, were identified. The studied PIPT interventions included (1) graded activity or graded exposure (n = 6), (2) cognitive-behavioral-based physical therapy (n = 9), (3) acceptance and commitment-based physical therapy (n = 1), and (4) internet-based psychological programs with physical therapy (n = 2). Consistent with prior reviews, graded activity is not superior to other forms of physical activity or exercise. In a few recent studies, cognitive-behavioral-based physical therapy had short-term efficacy when compared to a program of standardized exercise. There is a need to further examine approaches integrating alternative strategies including acceptance-based therapies (ie, acceptance and commitment therapy or mindfulness) or internet-based cognitive-behavioral programs within physical therapy. Although PIPT remains a promising care model, more convincing evidence is needed to support widespread adoption, especially in light of training demands and implementation challenges.

Psychosocial Mechanisms of Cognitive-Behavioral-Based Physical Therapy Outcomes After Spine Surgery: Preliminary Findings From Mediation Analyses

OBJECTIVE

Changing Behavior through Physical Therapy (CBPT), a cognitive-behavioral-based program, has been shown to improve outcomes after lumbar spine surgery in patients with a high psychosocial risk profile; however, little is known about potential mechanisms associated with CBPT treatment effects. The purpose of this study was to explore potential mediators underlying CBPT efficacy after spine surgery.

METHODS

In this secondary analysis, 86 participants were enrolled in a randomized trial comparing a postoperative CBPT (n = 43) and education program (n = 43). Participants completed validated questionnaires at 6 weeks (baseline) and 3 and 6 months following surgery for back pain (Brief Pain Inventory), disability (Oswestry Disability Index), physical health (12-Item Short-Form Health Survey), fear of movement (Tampa Scale for Kinesiophobia), pain catastrophizing (Pain Catastrophizing Scale), and pain self-efficacy (Pain Self-Efficacy Questionnaire). Parallel multiple mediation analyses using Statistical Package for the Social Sciences (SPSS) were conducted to examine whether 3- and 6-month changes in fear of movement, pain catastrophizing, and pain self-efficacy mediate treatment outcome effects at 6 months.

RESULTS

Six-month changes, but not 3-month changes, in fear of movement and pain self-efficacy mediated postoperative outcomes at 6 months. Specifically, changes in fear of movement mediated the effects of CBPT treatment on disability (indirect effect = -2.0 [95% CI = -4.3 to 0.3]), whereas changes in pain self-efficacy mediated the effects of CBPT treatment on physical health (indirect effect = 3.5 [95% CI = 1.2 to 6.1]).

CONCLUSIONS

This study advances evidence on potential mechanisms underlying cognitive-behavioral strategies. Future work with larger samples is needed to establish whether these factors are a definitive causal mechanism.

IMPACT

Fear of movement and pain self-efficacy may be important mechanisms to consider when developing and testing psychologically informed physical therapy programs.

An exploration of physiotherapists' perceived benefits and barriers towards using psychosocial strategies in their practice

BACKGROUND

This study aimed to determine what physiotherapists perceive are the benefits of using psychosocial strategies in their own practice, and whether perceived barriers extend beyond practitioner and contextual barriers.

METHODS

Content analysis of two open-ended questions was conducted. Australian physiotherapists (n = 206) provided written comments.

RESULTS

Three key categories of benefits emerged: patient benefits, shared patient and physiotherapist benefits, and physiotherapist benefits. Patient benefits included improved rehabilitation experience, improved patient wellbeing and improvement of psychosocial responses. Specifically, increased patient enjoyment, improved self-management and improved understanding of the links between their physical and psychological health. Therapeutic alliance appeared as a shared patient and physiotherapist benefit, with specific reference to enhanced partnerships and improved patient-centred practice. Physiotherapist benefits comprised of improved needs assessment and occupational benefits such as reduced load. Three key categories of physiotherapist barriers, contextual barriers, and patient barriers emerged. Time, knowledge, confidence, lack of expertise, and limited formal training, were the main barriers, specifically a lack of practical training, and for more complex strategies. Physiotherapists acknowledged patient barriers such as patient resistance, lack of understanding, and complex mental health needs.

CONCLUSIONS

These findings contribute novel information with regard to the benefits and barriers of psychosocial approaches from a physiotherapist perspective. Physiotherapists may benefit from further support in their use of psychosocial approaches, to emphasize the benefits for their own practice. Furthermore, to potentially reduce patient barriers and improve outcomes, patient education concerning a biopsychosocial model of care could be valuable.
