To What Degree Do Pain-coping Strategies Affect Joint Stiffness and Functional Outcomes in Patients with Hand Fractures?

Minimal Clinically Important Difference of the PROMIS Upper-Extremity Computer Adaptive Test and QuickDASH for Ligament Reconstruction Tendon Interposition Patients

PURPOSE

To calculate the minimal clinically important difference (MCID) of the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Test (UE CAT) and Quick-Disabilities of the Arm, Shoulder, and Hand (QuickDASH) for ligament reconstruction tendon interposition (LRTI) patients.

METHODS

Adult patients treated with LRTI for trapeziometacarpal OA by fellowship-trained hand surgeons between December 2014 and February 2018 at an academic tertiary institution were included. Outcomes were prospectively collected at each visit by tablet computer, including the QuickDASH, PROMIS UE, Pain Interference, Depression, and Anxiety CATs. Inclusion required a response to the anchor question "How much relief and/or improvement do you feel you have experienced as a result of your treatment?" on a 6-option Likert scale, as well as preoperative (≤120 days before surgery) and follow-up (2-26 weeks) outcomes. We calculated MCID both by an anchor-based approach using the mean score of the minimal change group, and with the 0.5 SD method.

RESULTS

Of 145 included participants, mean age was 63 ± 8 years and 74% were female. Anchor-based MCID estimates for the total cohort were 4.2 for the PROMIS UE CAT and 8.8 for the QuickDASH. The MCID estimates using the 0.5 SD method were 4.8 and 11.7, respectively.

CONCLUSIONS

We propose MCID values of 4.2 to 4.8 for the PROMIS UE CAT and 8.8 to 11.7 for the QuickDASH when powering clinical studies or when assessing improvement among a cohort of patients who have undergone LRTI surgery.

CLINICAL RELEVANCE

Minimal clinically important difference estimates are helpful when interpreting clinical outcomes after LRTI and for powering prospective trials.

Upper Extremity Function, Peer Relationships, and Pain Interference: Evaluating the Biopsychosocial Model in a Pediatric Hand Surgery Population Using PROMIS

PURPOSE

The relationship between biopsychosocial factors and patient-reported function is less clear in pediatric than in adult hand surgery patients. Our primary hypothesis was that pain interference (PI) and peer relationships (PR) would demonstrate association with upper extremity function. Secondarily, we hypothesized that the magnitude of this effect would increase with age.

METHODS

Patients aged 5 to 17 years presenting to a tertiary academic clinic between October 2017 and January 2019 were included. The parent/guardian was administered the following instruments after indicating they, rather than the patient, were answering the questions on a tablet computer: Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Parent Proxy (PP) Computer Adaptive Test (CAT) v2.0, PROMIS PI PP CAT v2.0, and the PROMIS PR PP CAT v2.0. Ceiling/floor effects and Spearman correlations were calculated. Multivariable Tobit modeling was performed to determine whether biopsychosocial factors and upper extremity function were associated. Multivariable regression coefficients were compared between age cohorts using a separate multivariable model to evaluate the interaction between age and other predictors.

RESULTS

Of 139 included participants, the mean age was 11.7 ± 3.7 years and 50% were female. For patients 11 years of age or younger, UE was weakly correlated with PI (coefficient, -0.34; 95% confidence interval, -0.56 to -0.08) and was not correlated with PR. For patients older than 11 years, UE had moderate correlation with PI (coefficient, -0.60; 95% confidence interval, -0.72 to -0.45) and was not correlated with PR. Multivariable analysis demonstrated a significant negative association between PI and UE, with a significantly larger magnitude of effect for patients older than 11 years of age.

CONCLUSIONS

The biopsychosocial model applies to pediatric hand surgery patients. The association between greater pain interference and worse patient-reported upper extremity function, as assessed using parent proxy instruments, was significantly stronger for patients older than 11 years than those 11 years old or younger.

CLINICAL RELEVANCE

This study suggests that the biopsychosocial model applies to pediatric hand patients.

Development and Usability Testing of a Web-Based and Therapist-Assisted Coping Skills Program for Managing Psychosocial Problems in Individuals With Hand and Upper Limb Injuries: Mixed Methods Study

Background

Ineffective coping has been linked to prolonged pain, distress, anxiety, and depression after a hand and upper limb injury. Evidence shows that interventions based on cognitive behavioral therapy (CBT) may be effective in improving treatment outcomes, but traditional psychological interventions are resource intensive and unrealistic in busy hand therapy practices. Developing web-based, evidence-based psychological interventions specifically for hand therapy may be feasible in clinical practice and at home with reduced training and travel costs. Hand Therapy Online Coping Skills (HOCOS) is a program developed to supplement traditional hand therapy with therapist-assisted coping skills training based on principles from CBT and the Technology Acceptance Model.

Objective

This study aimed to describe the development and assess the usability of HOCOS to support hand therapists in the management of psychosocial problems.

Methods

The ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) of system design was applied to create HOCOS. The usability testing of HOCOS involved a 2-stage process. In the first step, heuristic testing with information and communications technology (ICT) experts was completed using two sets of heuristics: Monkman heuristics and the Health Literacy Online (HLO) checklist. The second step involved user testing with hand therapists performing a series of online and face-to-face activities, completing 12 tasks on the website using the think-aloud protocol, completing the system usability scale (SUS) questionnaire, and a semistructured feedback interview in 2 iterative cycles. Descriptive statistics and content analyses were used to organize the data.

Results

In total, 4 ICT experts and 12 therapists completed usability testing. The heuristic evaluation revealed 15 of 35 violations on the HLO checklist and 5 of 11 violations on the Monkman heuristics. Initially, hand therapists found 5 tasks to be difficult but were able to complete all 12 tasks after the second cycle of testing. The cognitive interview findings were organized into 6 themes: task performance, navigation, design esthetics, content, functionality and features, and desire for future use. Usability issues identified were addressed in two iterative cycles. There was good agreement on all items of the SUS. Overall, therapists found that HOCOS was a detailed and helpful learning resource for therapists and patients.

Conclusions

We describe the development and usability testing of HOCOS; a new web-based psychosocial intervention for individuals with a hand and upper limb injuries. HOCOS targets psychosocial problems linked to prolonged pain and disability by increasing access to therapist-guided coping skills training. We actively involved target users in the development and usability evaluation of the website. The final website was modified to meet the needs and preferences of the participants.

Pain Catastrophizing Scale as a predictor of low postoperative satisfaction after hand surgery

Background

Psychological measures are used increasingly in outcome studies. The Pain Catastrophizing Scale is a 13-item questionnaire used to measure coping skills and negative feelings of pain. In the existing literature it is suggested that the Pain Catastrophizing Scale could be associated with the outcome following surgery. The aim of this study was to examine the effect of catastrophic thinking on postoperative satisfaction after treatment for hand conditions where pain is not the predominant symptom (Dupuytren's disease, trigger finger and wrist ganglia), and further to estimate cut-points on the Pain Catastrophizing Scale.

Methods

A total of 413 patients (53% females) with a mean age of 59 years were included in this one-year prospective follow-up study. The patients were diagnosed with either Dupuytren's disease (N = 133), trigger finger (N = 365), or wrist ganglia (N = 147). Preoperative data included disability (Disability of the Arm, Shoulder and Hand questionnaire (DASH)), quality of life (EuroQol-5D (EQ-5D)), and pain catastrophizing (Pain Catastrophizing Scale (PCS)). One year postoperative, data on DASH score, EQ-5D, and patient satisfaction were collected. We used a classification tree to define the most important cut-points, which could classify patients as low-risk or high-risk of low postoperative satisfaction. These cut-points and the 75th percentile cut-point was then used in logistic regression models with postoperative satisfaction as outcome variable.

Results

The median DASH score improved from 13.5 to 2.6 (p < 0.01), and the median EQ-5D score improved from 0.82 to 1.00, and 90.3% of patients were satisfied or very satisfied with the surgery.Using the 75th percentile (≤12) we did not find a predictive effect of PCS. However, when using the two cut-points from the classification tree (≤27.5 & ≤2.9) all tested models were statistically significant with odds ratios for risk of low satisfaction ranging from 2.81 to 6.44. Only the model using PCS ≤27.5 adjusted for both demographics and disability was insignificant.

Conclusion

This study suggests that PCS can be a valuable tool in predicting postoperative satisfaction in hand conditions where pain is not the predominant symptom, and that ≤27.5 and ≤ 2.9 are the optimal cut-point on the preoperative PCS.

Can an Integrative Care Approach Improve Physical Function Trajectories after Orthopaedic Trauma? A Randomized Controlled Trial

BACKGROUND

Orthopaedic trauma patients frequently experience mobility impairment, fear-related issues, self-care difficulties, and work-related disability []. Recovery from trauma-related injuries is dependent upon injury severity as well as psychosocial factors []. However, traditional treatments do not integrate psychosocial and early mobilization to promote improved function, and they fail to provide a satisfying patient experience.

QUESTIONS/PURPOSES

We sought to determine (1) whether an early psychosocial intervention (integrative care with movement) among patients with orthopaedic trauma improved objective physical function outcomes during recovery compared with usual care, and (2) whether an integrative care approach with orthopaedic trauma patients improved patient-reported physical function outcomes during recovery compared with usual care.

METHODS

Between November 2015 and February 2017, 1133 patients were admitted to one hospital as orthopaedic trauma alerts to the care of the three orthopaedic trauma surgeons involved in the study. Patients with severe or multiple orthopaedic trauma requiring one or more surgical procedures were identified by our orthopaedic trauma surgeons and approached by study staff for enrollment in the study. Patients were between 18 years and 85 years of age. We excluded individuals outside of the age range; those with diagnosis of a traumatic brain injury []; those who were unable to communicate effectively (for example, at a level where self-report measures could not be answered completely); patients currently using psychotropic medications; or those who had psychotic, suicidal, or homicidal ideations at time of study enrollment. A total of 112 orthopaedic trauma patients were randomized to treatment groups (integrative and usual care), with 13 withdrawn (n = 99; 58% men; mean age 44 years ± 17 years). Data was collected at the following time points: baseline (acute hospitalization), 6 weeks, 3 months, 6 months, and at 1 year. By 1-year follow-up, we had a 75% loss to follow-up. Because our data showed no difference in the trajectories of these outcomes during the first few months of recovery, it is highly unlikely that any differences would appear months after 6 months. Therefore, analyses are presented for the 6-month follow-up time window. Integrative care consisted of usual trauma care plus additional resources, connections to services, as well as psychosocial and movement strategies to help patients recover. Physical function was measured objectively (handgrip strength, active joint ROM, and Lower Extremity Gain Scale) and subjectively (Patient-Reported Outcomes Measurement Information System-Physical Function [PROMIS®-PF] and Tampa Scale of Kinesiophobia). Higher values for hand grip, Lower Extremity Gain Scale (score range 0-27), and PROMIS®-PF (population norm = 50) are indicative of higher functional ability. Lower Tampa Scale of Kinesiophobia (score range 11-44) scores indicate less fear of movement. Trajectories of these measures were determined across time points.

RESULTS

We found no differences at 6 months follow-up between usual care and integrative care in terms of handgrip strength (right handgrip strength β = -0.0792 [95% confidence interval -0.292 to 0.133]; p = 0.46; left handgrip strength β = -0.133 [95% CI -0.384 to 0.119]; p = 0.30), or Lower Extremity Gain Scale score (β = -0.0303 [95% CI -0.191 to 0.131]; p = 0.71). The only differences between usual care and integrative care in active ROM achieved by final follow-up within the involved extremity was noted in elbow flexion, with usual care group 20° ± 10° less than integrative care (t [27] = -2.06; p = 0.05). Patients treated with usual care and integrative care showed the same Tampa Scale of Kinesiophobia score trajectories (β = 0.0155 [95% CI -0.123 to 0.154]; p = 0.83).

CONCLUSION

Our early psychosocial intervention did not change the trajectory of physical function recovery compared with usual care. Although this specific intervention did not alter recovery trajectories, these interventions should not be abandoned because the greatest gains in function occur early in recovery after trauma, which is the key time in transition to home. More work is needed to identify ways to capitalize on improvements earlier within the recovery process to facilitate functional gains and combat psychosocial barriers to recovery.

Factors influencing functional outcome of proximal interphalangeal joint collateral ligament injury when treated with buddy strapping and exercise

STUDY DESIGN

Prospective cohort.

INTRODUCTION AND PURPOSE

This study evaluates the factors influencing treatment outcomes of proximal interphalangeal (PIP) joint collateral ligament injuries when treated with buddy strapping.

METHODS

Sixty-seven patients treated with buddy strapping for a PIP joint injury were enrolled. The finger range of motion (ROM), grip strength, and a Quick Disability of the Arm, Shoulder, and Hand (QuickDASH) score were assessed at 3 and 6 months after the initial injury. The factors that were assessed for their influence on the functional outcomes included age, sex, hand dominance, affected finger, type of injury, injury severity, time to treatment, the duration of buddy strapping, and exercise training.

RESULTS

Buddy strapping for PIP joint injuries led to satisfactory results with 77% recovery of grip strength, 84% recovery in ROM, and mean QuickDASH scores of 14 at 6 months. A decrease in grip strength was associated with an increase in age and injury severity at 6 months, and these 2 factors accounted for 22% of the variance in the grip strength. A decrease in ROM was associated with the delayed treatment, which accounted for 18% of the variance in ROM at 6 months. An increased disability was associated with delayed treatment, female gender, and radial digit injury at 3 months, and these 3 factors accounted for 37% of the variance in disability. At 6 months, only the delayed treatment remained an associated factor, which accounted for 20% variance in disability.

DISCUSSION AND CONCLUSIONS

PIP collateral ligament injuries had very good outcomes with buddy strapping. However, delayed treatment was significantly associated with poor functional outcomes in terms of the ROM and disability. An increase in age and injury severity were associated with lower grip strength up to 6 months, whereas a female gender and radial digit injury were associated with an increased disability up to 3 months.

Minimal Clinically Important Difference After Carpal Tunnel Release Using the PROMIS Platform

PURPOSE

In light of recently-proposed quality measures for carpal tunnel release (CTR), elucidating the minimal clinically important difference (MCID) for selected outcome measures will be important when interpreting treatment responses. Our purpose was to estimate the MCID of the Patient-Reported Outcomes Measurement Information System (PROMIS) instruments and the short Disabilities of the Arm, Shoulder, and Hand (QuickDASH) following CTR.

METHODS

Adult patients undergoing isolated unilateral CTR between July 2014 and October 2016 were identified. Outcomes included the PROMIS Upper Extremity (UE) Computer Adaptive Test (CAT), Physical Function (PF) CAT, QuickDASH, and Pain Interference (PI) CAT. For inclusion, pretreatment baseline (within 60 days of surgery) and postoperative (6-90 days) UE or PF CAT scores were required, as well as a response on a 5-point Likert scale to the question "How much relief and/or improvement do you feel you have experienced as a result of your treatment?" The MCID was calculated using SD and minimum detectable change (MDC) distribution methods.

RESULTS

In response to the Likert scale question, 88.6% of patients reported improvement at a mean of 14.8 days after surgery. The infrequency of patients reporting no change (5 of 44; 11.4%) precluded calculation of a statistically sound anchor-based MCID value. The MCID values, as calculated using the one-half SD method, were 3.6, 4.6, 10.4, and 3.4 for the UE CAT, PF CAT, QuickDASH, and PI CAT, respectively.

CONCLUSIONS

We have calculated MCID values for the UE CAT, PF CAT, QuickDASH, and PI CAT for patients undergoing CTR. Although the small number of patients reporting no change and minimal change after surgery precluded an anchor-based MCID calculation, we report estimates using the one-half SD method for the MCID following CTR.

CLINICAL RELEVANCE

These MCID estimates will be helpful when interpreting CTR clinical outcomes and for powering prospective trials.

Factors associated with the magnitude of limitations during recovery from a fracture of the proximal humerus

Aims

The purpose of this study was to identify factors associated with limitations in function, measured by patient-reported outcome measures (PROMs), six to nine months after a proximal humeral fracture, from a range of demographic, injury, psychological, and social variables measured within a week and two to four weeks after injury.

Patients and Methods

We enrolled 177 adult patients who sustained an isolated proximal humeral fracture into the study and invited them to complete PROMs at their initial outpatient visit within one week of injury, between two and four weeks, and between six to nine months after injury. There were 128 women and 49 men; the mean age was 66 years (sd 16; 18 to 95). In all, 173 patients completed the final assessment. Bivariate analysis was performed followed by multivariable regression analysis accounting for multicollinearity using partial R2, correlation matrices, and variable inflation factor.

Results

Many variables within a week of injury and between two and four weeks after injury correlated with six- to nine-month PROMs in bivariate analysis. Kinesiophobia measured within a week of injury (Tampa Scale for Kinesiophobia-11: partial R2 = 0.14; p = 0.000) and self-efficacy measured between two and four weeks (Pain Self-efficacy Questionnaire-2: partial R2 = 0.266; p < 0.001) were the strongest predictors of limitations (measured by Patient Reported Outcome Measurement Information System Upper Extremity Physical Function Computer Adaptive Test (PROMIS UE)) at six to nine months in multivariable analysis. Similar findings were observed with other types of PROM. Regression models accounted for a substantial amount of variance in all PROMs at both timepoints (e.g. 66% of the overall variance within one week, and 70% within two to four weeks for PROMIS UE at six to nine months).

Conclusion

Recovery from a proximal humeral fracture appears to be enhanced by overcoming fears of movement or reinjury within a week after injury and greater self-efficacy (developing resilience and more effective coping strategies) within a month. Such factors are modifiable using enhanced communication skills and cognitive behavioural treatments. These findings could be a catalyst for the routine assessment and treatment of psychological and social factors in the management of patients with fractures.

What Factors Are Associated With Disability After Upper Extremity Injuries? A Systematic Review

BACKGROUND

Psychosocial factors are key determinants of health after upper extremity injuries. However, a systematic review is needed to understand which psychosocial factors are most consistently associated with disability and how the language, conceptualization, and types of measures used to assess disability impact these associations in upper extremity injuries.

QUESTIONS/PURPOSES

(1) What factors are most consistently associated with disability after upper extremity injuries in adults? (2) What are the trends in types of outcome measures and conceptualization of disability in patients' upper extremity injuries?

METHODS

We searched multiple electronic databases (PubMED, OVIDSP, PsycInfo, Google Scholar, ISI Web of Science) between January 1, 1996, and December 31, 2016, using terms related to the "upper extremity", "outcome measurement", and "impairment, psychological, social or symptomatic" variables. We included all studies involving adult patients with any musculoskeletal injury and excluded those that did not use patient-reported outcome measures. We identified and screened 9339 studies. Of these, we retained 41 studies that involved conditions ranging from fractures to soft tissue injuries in various regions of the arm. We conducted quality assessment using a 10-item validated checklist and a five-tier strength of evidence assessment. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) criteria and registered the review before performing our search (PROSPERO: CRD42017054048). None of the authors received any funding to perform this work.

RESULTS

Disability after upper extremity injury was most consistently associated with depression (21 cohorts), catastrophic thinking (13 cohorts), anxiety (11 cohorts), pain self-efficacy (eight cohorts), and pain interference (seven cohorts). Social and demographic factors were also associated with disability. Measures of impairment such as ROM and injury severity were least associated with disability. There has been a gradual increase in use of region or condition-specific patient-reported outcome measures and measures of psychological, social, and symptomatic factors over a period since the introduction of the World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF) around 2000. Approximately 17% of studies (n = 454 of 2628) had instances of unclear, conflicting, or inappropriate terminology and 11% of studies (n = 257 of 2628) involved misrepresentations of outcome measures related to disability.

CONCLUSIONS

Psychologic and social factors are most consistently associated with disability than factors related to impairment. Further research involving the assessment of depression, anxiety, and coping strategies in cohorts with specific injuries may support decision-making regarding the provision of emotional support and psychologic therapies during recovery. Using the WHO ICF framework to conceptualize disability is key in increasing strength of evidence and allowing accurate comparisons of research in this field.

Systematic review: Predicting adverse psychological outcomes after hand trauma

STUDY DESIGN

Systematic review.

INTRODUCTION AND PURPOSE OF THE STUDY

After traumatic hand injury, extensive physical and psychological adaptation is required following surgical reconstruction. Recovery from injury can understandably be emotionally challenging, which may result in impaired quality of life and delayed physical recovery. However, the evidence base for identifying high-risk patients is limited.

METHODS

A PROSPERO-registered literature search of MEDLINE (1946-present), EMBASE (1980-present), PsychInfo, and CINAHL electronic databases identified 5156 results for studies reporting psychological outcomes after acute hand trauma. Subsequent review and selection by 2 independent reviewers identified 19 studies for inclusion. These were poor quality level 2 prognostic studies, cross sectional or cohort in design, and varied widely in methodology, sample sizes, diagnostic methods, and cutoff values used to identify psychological symptoms. Data regarding symptoms, predisposing factors, and questionnaires used to identify them were extracted and analyzed.

RESULTS

Patients with amputations or a tendency to catastrophize suffered highest pain ratings. Persisting symptom presence at 3 months was the best predictor of chronicity. Many different questionnaires were used for symptom detection, but none had been specifically validated in a hand trauma population of patients. Few studies assessed the ability of selection tools to predict patients at high risk of developing adverse psychological outcomes.

DISCUSSION AND CONCLUSION

Despite a limited evidence base, screening at 3 months may detect post-traumatic stress disorder, anxiety, depression, and chronic pain, potentially allowing for early intervention and improved treatment outcomes.

Hand Posturing Is a Nonverbal Indicator of Catastrophic Thinking for Finger, Hand, or Wrist Injury

BACKGROUND

Prior research documents that greater psychologic distress (anxiety/depression) and less effective coping strategies (catastrophic thinking, kinesophobia) are associated with greater pain intensity and greater limitations. Recognition and acknowledgment of verbal and nonverbal indicators of psychologic factors might raise opportunities for improved psychologic health. There is evidence that specific patient words and phrases indicate greater catastrophic thinking. This study tested proposed nonverbal indicators (such as flexion of the wrist during attempted finger flexion or extension of uninjured fingers as the stiff and painful finger is flexed) for their association with catastrophic thinking.

QUESTIONS/PURPOSES

(1) Do patients with specific protective hand postures during physical examination have greater pain interference (limitation of activity in response to nociception), limitations, symptoms of depression, catastrophic thinking (protectiveness, preparation for the worst), and kinesophobia (fear of movement)? (2) Do greater numbers of protective hand postures correlate with worse scores on these measures?

METHODS

Between October 2014 and September 2016, 156 adult patients with stiff or painful fingers within 2 months after sustaining a finger, hand, or wrist injury were invited to participate in this study. Six patients chose not to participate as a result of time constraints and one patient was excluded as a result of inconsistent scoring of a possible hand posture, leaving 149 patients for analysis. We asked all patients to complete a set of questionnaires and a sociodemographic survey. We used Patient Reported Outcomes Measurement Information System (PROMIS) Depression, Upper Extremity Physical Function, and Pain Interference computer adaptive test (CAT) questionnaires. We used the Abbreviated Pain Catastrophizing Scale (PCS-4) to measure catastrophic thinking in response to nociception. Finally, we used the Tampa Scale of Kinesophobia (TSK) to assess fear of movement. The occurrence of protective hand postures during the physical examination was noted by both the physician and researcher. For uncertainty or disagreement, a video of the physical examination was recorded and a group decision was made.

RESULTS

Patients with one or more protective hand postures did not score higher on the PROMIS Pain Interference CAT (hand posture: 59 [56-64]; no posture: 59 [54-63]; difference of medians: 0; p = 0.273), Physical Function CAT (32 ± 8 versus 34 ± 8; mean difference: 2 [confidence interval {CI}, -0.5 to 5]; p = 0.107), nor the Depression CAT (48 [41-55] versus 48 [42-53]; difference of medians: 0; p = 0.662). However, having at least one hand posture was associated with a higher degree of catastrophic thinking (PCS scores: 13 [6-26] versus 10 [3-16]; difference of medians: 3; p = 0.0104) and a higher level of kinesophobia (TSK: 40 ± 6 versus 38 ± 6; mean difference: -2 [CI, -4 to -1]; p = 0.0420). Greater catastrophic thinking was associated with a greater number of protective hand postures on average (rho: 0.20, p = 0.0138).

CONCLUSIONS

Protective hand postures and (based on prior research) specific words and phrases are associated with catastrophic thinking and kinesophobia, less effective coping strategies that hinder recovery. Surgeons can learn to recognize these signs and begin to treat catastrophic thinking and kinesophobia starting with compassion, empathy, and patience and be prepared to add formal support (such as cognitive-behavioral therapy) to help facilitate recovery.

Preoperative Pain Sensitization Is Associated With Postoperative Pillar Pain After Open Carpal Tunnel Release

BACKGROUND

Postoperative pillar pain (deep-seated wrist pain worsened by leaning on the heel of the hand) sometimes occurs after carpal tunnel release (CTR), leading to weakness in the hand and delayed return to work. Increased pain sensitivity has been found to be associated with worse symptoms and poorer treatment response in a number of chronic musculoskeletal conditions, but few studies have investigated the association of pain sensitization with pillar pain after CTR.

QUESTIONS/PURPOSES

(1) Is preoperative pain sensitization in patients with carpal tunnel syndrome (CTS) associated with increased severity of pillar pain after open CTR? (2) What other demographic, electrophysiological, or preoperative clinical characteristics are associated with pillar pain after CTR?

METHODS

Over a 35-month period, one surgeon performed 162 open carpal tunnel releases. Patients were eligible if they had sufficient cognitive and language function to provide informed consent and completed a self-reported questionnaire; they were not eligible if they had nerve entrapment other than CTR or if the surgery was covered by workers compensation insurance. Based on these criteria, 148 (91%) were approached for this study. Of those, 17 (9%) were lost to followup before 12 months, leaving 131 for analysis. Their mean age was 54 years (range, 32-78 years), and 81% (106 of 131) were women; 34% (45 of 131) had less than a high school education. We preoperatively measured pain sensitization by assessing the patients' pressure pain thresholds by stimulating pressure-induced pain in the pain-free volar forearm and administering a self-reported Pain Sensitivity Questionnaire minor subscale, an instrument that assesses pain intensity in daily life situations. We evaluated postoperative pillar pain using the "table test" (having the patient lean on a table with their weight on their hands placed on the table's edge with elbows straight) with an 11-point ordinal scale at 3, 6, and 12 months after their surgical procedures. We conducted bivariate and multivariable analyses to determine whether the patients' clinical, demographic, and pain sensitization factors were associated with their postoperative pillar pain severity after CTR.

RESULTS

After controlling for relevant confounding variables such as age, education level, and functional states, we found that increased pillar pain severity was associated with the pressure pain threshold (β = -1.02 [-1.43 to -0.61], partial R = 11%, p = 0.021) and Pain Sensitivity Questionnaire minor (β = 1.22 [0.73-1.71], partial R = 17%, p = 0.013) at 3 months, but by 6 months, only Pain Sensitivity Questionnaire minor (β = 0.92 [0.63-1.21], partial R = 13%, p = 0.018) remained an associated variable for pillar pain. Additionally, gender (women) was associated with increased pain severity at 3 (β = 0.78 [0.52-1.04], partial R = 9%, p = 0.023) and 6 months (β = 0.72 [0.41-1.01], partial R = 8%, p = 0.027). At 3 months, pressure pain threshold, Pain Sensitivity Questionnaire minor, and gender (women) collectively accounted for 37% of the variance in pillar pain severity; at 6 months, Pain Sensitivity Questionnaire minor and gender (women) accounted for 21% of the variance, but no relationship between those factors and pillar pain was observed at 12 months.

CONCLUSIONS

Gender (women) and preoperative pain sensitization measured by pressure pain threshold and self-reported Pain Sensitivity Questionnaire were associated with pillar pain severity up to 3 and 6 months after CTR, respectively. However, the influence of pain sensitization on pillar pain was diminished at 6 months and it did not show persistent effects beyond 12 months. Pain sensitization seems to be more important in the context of recovery from surgical intervention (in the presence of a pain condition) than in healthy states, and clinicians should understand the role of pain sensitization in the postoperative management of CTS. Future research may be needed to determine if therapeutic interventions to reduce sensitization will decrease the risk of pillar pain.

Association of Physical Function, Anxiety, and Pain Interference in Nonshoulder Upper Extremity Patients Using the PROMIS Platform

PURPOSE

The relationship between psychosocial factors and self-reported physical function among hand and upper extremity patients is complex. The Patient-Reported Outcomes Measurement Information System (PROMIS) platform has attempted to create a variety of specifically targeted metrics that can be administered using computer adaptive testing (CAT). Three metrics measuring self-reported physical function (herein referred to in combination as "functional" metrics) include the PROMIS Physical Function (PF) CAT, PROMIS Upper Extremity (UE) CAT, and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH). Two metrics assessing psychosocial factors include the PROMIS Anxiety and Pain Interference (PI) CATs ("nonfunctional" metrics). This study evaluates whether the functional metrics were correlated with nonfunctional metrics.

METHODS

The 5 questionnaires were administered prospectively on a tablet computer to all consecutive adult patients presenting to an outpatient hand and upper extremity (nonshoulder) clinic at a tertiary academic medical center from January 1 to November 1, 2014. For patients with multiple visits during the study period, only the first was included. Data were evaluated retrospectively to assess the relationship between functional and nonfunctional measures, with Pearson correlation coefficients to understand the relationship between continuous variables, and 1-way analysis of variance to examine for differences in outcome measures across demographic groups. Multivariable linear regression analyses were performed to determine factors predicting functional disability.

RESULTS

We included 1,299 patients: mean age was 46.8 years, 53% were female, and 23% were unemployed or on disability. The PROMIS PF CAT, PROMIS UE CAT, and QuickDASH scores were all significantly correlated with PROMIS Anxiety CAT (Pearson correlation coefficients, -0.46, -0.48, and 0.53, respectively) and PROMIS PI CAT (-0.60, -0.65, and 0.76, respectively) scores. Multivariable regression analyses demonstrated that increased PROMIS Anxiety and PI CAT scores each independently and adversely influenced PROMIS PF CAT, PROMIS UE CAT, and QuickDASH scores.

CONCLUSIONS

Increasing levels of patient anxiety and pain interference are independently associated with decreased patient-reported upper extremity function.

CLINICAL RELEVANCE

This study provides further support of the biopsychosocial model by highlighting that increased anxiety is associated with decreased self-reported function using the PROMIS platform.

Clinician and Patient-reported Outcomes Are Associated With Psychological Factors in Patients With Chronic Shoulder Pain

BACKGROUND

Validated clinician outcome scores are considered less associated with psychosocial factors than patient-reported outcome measurements (PROMs). This belief may lead to misconceptions if both instruments are related to similar factors.

QUESTIONS

We asked: In patients with chronic shoulder pain, what biopsychosocial factors are associated (1) with PROMs, and (2) with clinician-rated outcome measurements?

METHODS

All new patients between the ages of 18 and 65 with chronic shoulder pain from a unilateral shoulder injury admitted to a Swiss rehabilitation teaching hospital between May 2012 and January 2015 were screened for potential contributing biopsychosocial factors. During the study period, 314 patients were screened, and after applying prespecified criteria, 158 patients were evaluated. The median symptom duration was 9 months (interquartile range, 5.5-15 months), and 72% of the patients (114 patients) had rotator cuff tears, most of which were work injuries (59%, 93 patients) and were followed for a mean of 31.6 days (SD, 7.5 days). Exclusion criteria were concomitant injuries in another location, major or minor upper limb neuropathy, and inability to understand the validated available versions of PROMs. The PROMs were the DASH, the Brief Pain Inventory, and the Patient Global Impression of Change, before and after treatment (physiotherapy, cognitive therapy and vocational training). The Constant-Murley score was used as a clinician-rated outcome measurement. Statistical models were used to estimate associations between biopsychosocial factors and outcomes.

RESULTS

Greater disability on the DASH was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale combined coefficient, 0.64; 95% CI, 0.25-1.03; p = 0.002) and social factors (language, professional qualification combined coefficient, -6.15; 95% CI, -11.09 to -1.22; p = 0.015). Greater pain on the Brief Pain Inventory was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale combined coefficient, 0.076; 95% CI, 0.021-0.13; p = 0.006). Poorer impression of change was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia coefficient, 0.93; 95% CI, 0.87-0.99; p = 0.026) and social factors (education, language, and professional qualification coefficient, 6.67; 95% CI, 2.77-16.10; p < 0.001). Worse clinician-rated outcome was associated only with psychological factors (Hospital Anxiety and Depression Scale (depression only), Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia combined coefficient, -0.35; 95% CI, -0.58 to -0.12; p = 0.003).

CONCLUSIONS

Depressive symptoms and catastrophizing appear to be key factors influencing PROMs and clinician-rated outcomes. This study suggests revisiting the Constant-Murley score.

Early occupational performance intervention enhances outcome after distal radius fracture: A nonrandomized controlled trial

Introduction

Distal radius fractures are common in women aged over 50. Common complications are pain, oedema, and finger stiffness, which can impact the ability to perform many daily activities. An exercise program for mobility and strength is a traditional early treatment. Little is known about the influence of occupational performance intervention in the early stage. The aim was to evaluate the effect of early intervention at the emergency department focusing on occupational performance in women over 50 years with distal radius fracture.

Methods

A nonrandomized controlled trial, with an intervention group ( n = 24) and a control group ( n = 24). The intervention group had a dialogue with an occupational therapist highlighting activity issues in the present situation. The control group got treatment as usual. Patient reported outcome measures were used as assessment at an estimated baseline, 1 week, 4 to 5 weeks, and 7 to 8 weeks after injury with COPM, DASH, and a single question about perceived independence of occupational performance. Change over time and differences between groups were calculated.

Results

Both groups improved their occupational performance significantly during the 2 months follow up, but the intervention group valued their improved ability and independence significantly higher than the control group. Some of the participants in the intervention group scored within normative values for women with DASH, already at 4 to 5 weeks and 7 to 8 weeks after the injury.

Conclusions

The results indicate potential importance of very early occupational performance intervention at the emergency department, as a valuable complement to traditional treatment of distal radius fracture.
