Compensation by the Uninjured Arm After Brachial Plexus Injury

Danish translation, cultural adaptation and psychometric testing of the Brachial Assessment Tool (BrAT), designed to assess activity limitation in adults with traumatic brachial plexus injuries

PURPOSE

To translate and cross-culturally adapt The Brachial Assessment Tool (BrAT) into Danish and assess its content validity and reproducibility in adults with traumatic brachial plexus injury (BPI).

MATERIAL AND METHODS

Translation followed international guidelines. BrAT(DK) were cognitive tested with 19 adults with traumatic BPI to evaluate cross-cultural understanding, relevance, comprehensiveness and comprehensibility. Content validity and reproducibility were evaluated following the COnsensus-based Standards for the selection of health Measurement INstruments guideline. Participants were recruited from an outpatient hand clinic. Test-retest reliability was assessed using intra-class-correlation coefficient (ICC) and the smallest detectable change (SDC). Internal consistency was evaluated using Cronbach's alpha.

RESULTS

Minor cultural differences were observed in the content validity analysis of BrAT(DK). Cognitive testing revealing no significant issues. All participants found the items relevant and important. 63 participants with traumatic BPI were recruited; 49 completed the retest. ICC values for the sub-scales and the total score ranged from 0.91 to 0.95 (95% CI 0.85 to 0.97). Internal consistency ranged from 0.87 to 0.98. SDC ranged from 4.16 to 9.63 for subscales and 16.01 for the total score.

CONCLUSION

BrAT(DK) appeared to be content valid and reliabel as a measure of activity limitation in adults with traumatic BPI.

Musculoskeletal complaints, physical work demands, and functional capacity in individuals with a brachial plexus injury: An exploratory study

BACKGROUND

Musculoskeletal complaints (MSCs) may be more common in individuals with brachial plexus injury (BPI), whose physical work demands exceed their functional capacity (FC).

OBJECTIVES

(a) To assess the concurrent validity of five methods for measuring upper extremity work demands and the Dictionary of Occupational Titles (DOT). (b) To explore the relations between MSCs, physical work demands, and FC in individuals with BPI.

METHODS

This study had a descriptive correlational design. Physical work demands of 16 individuals with BPI (12 males, 6 one-handed workers) were assessed during work using five assessment methods and the DOT. Spearman correlation coefficients between work demand methods were determined. FC was assessed using the functional capacity evaluation one-handed (FCE-OH). A questionnaire was used to examine MSCs. The relationship between MSCs, physical work demands and FC was analyzed visually, using Spearman correlation coefficients, and by comparing FCE-OH results to FCE reference values.

RESULTS

Spearman correlation coefficients for the DOT and four out of five assessment methods for determining work demands on upper extremities were significant and moderate (four combinations: r = 0.65-0.79) to strong (five combinations: r = 0.81-0.94). Correlations of the fifth method with the other methods were weak to fair. No significant relationships were found between MSCs, physical work demands and FCE-OH results.

CONCLUSION

The relationships between MSCs, physical work demands, and FC are evidently complex and require further investigation. In this small sample the concurrent validity of the DOT and four methods for determining work demands on upper extremities was moderate to good.

Linking assessment instruments for brachial plexus injury to the international classification of functioning, disability and health

BACKGROUND

Brachial plexus injuries (BPI) affect not only body structure and function, but also several aspects of individual's well-being. Considering the crescent need for assessing such patients through a biopsychosocial perspective, linking meaningful concepts of BPI instruments to the International Classification of Functioning, Disability and Health (ICF) provides a useful overview of how the ICF components are contemplated on the current measurements available.

PURPOSE

To identify patient-reported outcome measures (PROMs) specifically designed for BPI assessment and link the content with the ICF.

STUDY DESIGN

Content Analysis through ICF linking.

METHODS

The study was conducted in two steps: the first one encompassed a literature review to identify questionnaires specifically designed for assessing patients with BPI, where two PROMs were eligible: the Brachial Assessment Tool (BrAT) and the Impact of Brachial Plexus Injury Questionnaire (IBPIQ); in the second phase, the items of such instruments were linked to the ICF by two independent reviewers, in accordance to the methodology proposed by Cieza et al.

RESULTS

54 different significant concepts were identified from the 74 questionnaire items and linked to 49 distinct ICF categories. The categories were mostly related to the activities and participation component (56.9%, n = 29), followed by body functions (27.45%, n = 14), body structures (9.8%, n = 5) and environmental factors component (1.96%, n = 1).

CONCLUSION

The questionnaires developed for adults with BPI were BrAT and IBPIQ. Although both instruments presented with a diverse coverage of ICF components, their content had a major focus on activities and participation domain and poorly or did not addressed environmental factors. Thus, other instruments could be considered in a complementary way for clinical assessment.

Prevalence and factors associated with musculoskeletal complaints and disability in individuals with brachial plexus injury: a cross-sectional study

PURPOSE

(1) To determine the prevalence of musculoskeletal complaints (MSCs) in the non-affected bodily structures in individuals with brachial plexus injury (BPI) and (2) to analyse factors associated with MSCs and disability.

METHODS

Survey among individuals with BPI and a control group. Multivariable logistic and linear regression analyses were used to identify factors associated with MSCs or disability.

RESULTS

Forty-nine percent of individuals (34/70) with BPI experienced MSC, which was not significantly different from controls (35%, n = 40/113). Complaints were most often located in high back (OR  =  3.6) or non-affected limb (OR  =  2.2) or neck (OR  =  2.1). Greater disability was associated with the presence of MSC in individuals with BPI (OR  =  1.1, 95% confidence interval (95% CI) = 1.0; 1.1). Those with no or a low level of education (B = -10.2, 95% CI = -19.6; -1.4), a history of nerve surgery (B = 11.1, 95% CI = -0.2; 20.9), and moderately affected active range of motion (AROM) of the affected limb (B = 20.7, 95% CI  =  8.8; 31.0) experienced most disability. Individuals with severely affected AROM showed a wide range of experienced disability.

CONCLUSIONS

Clinicians should be aware that almost half of individuals with BPI have MSCs in the non-affected bodily structures, which was associated with increased disability.Implications for rehabilitationMusculoskeletal complaints of the non-affected limb, back and neck are common among individuals with brachial plexus injury, and are associated with more disability.Disability was associated with loss of active range of motion (AROM) in the affected limb, although there was a wide variation in experienced disability among individuals with no or a very limited AROM.

Functional capacity of individuals with brachial plexus injury

BACKGROUND

To enable (pain free) functioning, individuals with brachial plexus injury (BPI) may require a higher functional capacity compared to two-handed individuals, because the load on unaffected structures is greater.

OBJECTIVE

This study compared the functional capacity of individuals with BPI and healthy controls and explored differences in the functional capacity of BPI-affected individuals with respect to: those with and without hand function; affected and unaffected sides; with and without musculoskeletal complaints (MSCs).

METHODS

Six functional capacity tests adjusted for one-handed function were performed by 23 BPI-affected individuals and 20 healthy controls. Hand function was assessed through physical examination and the Dutch Musculoskeletal Questionnaire was used to assess MSCs.

RESULTS

Individuals with BPI scored lower for the two-handed tests, compared with the controls (p≤0.01, effect size (r) ≤-0.41 for both tests). However, both groups performed similar in the one-handed tests. On average individuals with BPI met the physical demands to perform sedentary to light physical work. Among BPI-affected individuals, two-handed overhead lifting capacity was higher in those with hand function than in those without hand function (p = 0.02; r = 0.33). Functional capacity tended to be lower for the unaffected side than for the affected side (4 tests; p≤0.05, r≤-0.36). Test results of BPI-affected Individuals with and without MSCs were similar.

CONCLUSION

Individuals with BPI demonstrated lower two-handed functional capacity than healthy controls. Effect sizes were medium. Capacity of their unaffected side was similar to the dominant side of controls. No association was found between MSCs and functional capacity.

Psychometric Evaluation of the Disabilities of the Arm, Shoulder and Hand Outcome Questionnaire for Brachial Plexus Injury Using Rasch Analysis

Background: Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire is the most widely used patient-reported outcome measure (PROM) for assessment of upper extremity disability assessment. However, DASH is a multidimensional measurement with different difficulty levels and ratio apportionment of the items categorised by ordinal scale. This has caused a misinterpretation of the total disability scores. We created a modified DASH adapted to the Rasch model. The aim of this study is to compare the functional recovery and quality of life (QOL) improvement and to assess the validity of the original DASH and modified DASH between C56/C567, C5-8 and total types of brachial plexus injury (BPI) following surgical reconstruction. Methods: A total of 183 BPI patients who underwent reconstructive surgery were evaluated for functional recovery using the range of motion and power of the affected limb, and improvement in QOL with DASH. The collected data were analysed using Rasch measurement theory to detect the misfit items. The original and modified DASH were compared under the three different types of BPI after item reduction by removing the misfit items. Results: There were significant differences in functional recovery between three types of palsy. However, PROM using DASH score with or without misfit items (12 items) did not show any significant differences. Conclusions: DASH is not suitable for comparison of upper extremity disabilities even after being corrected mathematically due to the inclusion of items from many different domains unequally. Therefore, each item of the function (with or without compensation of the uninjured hand), pain and impact to the patients should be evaluated separately. Level of Evidence: Level IV (Prognostic).

Patient Perception after Traumatic Brachial Plexus Injury - A Qualitative Case Report

STUDY DESIGN

This is a qualitative case study.

INTRODUCTION

Considering individual patient's perception is an important aspect of rehabilitation according to International Classification of Functioning model (Geneva, 2002).

PURPOSE OF STUDY

The report highlights the importance of patient education and considering individual's perception to achieve rehabilitation outcomes.

METHOD

A written informed consent for case report was given by a 24-year-old male, a mass media graduate student diagnosed with global brachial plexus injury. Detailed evaluation by a senior therapist was conducted in a tertiary government hospital using the following tools: RESULT: Patient education and rehabilitation led to signs of clinical improvement at the end of 5 months. In spite of this clinical signs of recovery, patient showed lack of satisfaction in terms of his appearance and body image.

DISCUSSION

As employment and social life determined our patient's satisfaction level, a negative impact was seen on functional recovery.

CONCLUSION

Considering an individual's perception regarding the condition in terms of their contextual and personal factors is an important aspect of rehabilitation according to International Classification of Functioning model (Geneva, 2002).

Outcomes after occupational therapy intervention for traumatic brachial plexus injury: A prospective longitudinal cohort study

STUDY DESIGN

Prospective longitudinal cohort study.

INTRODUCTION

Traumatic brachial plexus injuries (BPIs) can be devastating and negatively impact daily function and quality of life. Occupational therapists play an important role in rehabilitation; however, studies identifying outcomes are lacking.

PURPOSE

This study aims to describe outcomes including motor recovery, upper limb function, participation, pain, and quality of life for people receiving occupational therapy intervention.

METHODS

A convenience sample of English-speaking adults (n = 30) with a traumatic BPI, attending the clinic between December 1, 2014, to November 30, 2016, participated. Participants received occupational therapy focusing on sensorimotor retraining and activity-based rehabilitation. Data on active range of motion (goniometry), strength (Medical Research Council (MRC)), upper-limb function (UEFI15, QuickDASH), participation (PSFS), pain (Brief Pain Inventory), and quality of life (EQ-5D-3L) were collected at baseline, 3, 6, 9, and 12 months.

RESULTS

Elbow flexion strength showed significant improvement at all time-points, average increase 2.17 (MRC) (95% confidence interval: 1.29-3.04; P < .001) and mean final MRC grading 3.86 (standard error: 0.44). Significant improvements at 12 months were seen in: shoulder abduction strength and range, flexion strength and range, external rotation range; elbow extension strength and flexion range; thumb flexion and extension strength. Upper limb function (QuickDASH) showed significant improvement (mean change = 18.85; 95% confidence interval: 4.12-33.59; P = .02). Forearm protonation range and finger flexion strength were significantly worse. Remaining outcomes did not show significant improvement.

CONCLUSIONS

Occupational therapy with surgical intervention can improve strength, range, and upper limb function with people following traumatic BPI. Further investigations into impact on participation, pain, and quality of life are required.

Predictive factors for return to work or study and satisfaction in traumatic brachial plexus injury individuals undergoing rehabilitation: A retrospective follow-up study of 101 cases

BACKGROUND

An important focus of rehabilitation is thereturn to the meningful occupations which may include work and school activities.

PURPOSE

The aim of this study is to investigate predictive factors for return to work/study in traumatic brachial plexus injury patients undergoing rehabilitation and to investigate the level of satisfaction with treatment.

STUDY DESIGN

Retrospective observational study with at least 1 year of follow-up.

METHODS

One hundred and one individuals with traumatic brachial plexus injury enrolled in this study. Primary outcomes were return to work/study and satisfaction with treatment. A secondary outcome was the self-perception of what influenced return to work. Sociodemographic and related to injury data, rehabilitation interventions, muscle strength, and disability were analyzed as predictors. Associations were investigated using univariable and discriminant analysis and considered a level of significance of P < .05.

RESULTS

Return to work/study occurred in 55% of the patients who participated in this study. Muscle strength discerned those who returned to work. Time interval between trauma and surgery and age were lower in those who returned to work. Thirty-one patients answered the question regarding self-perception of what influenced return to work. They indicated "necessity", "rehabilitation", "my desire" and "not become depressed". Satisfaction was graded between 8.9 and 9.5 in 95% of the cases.

CONCLUSIONS

Return to work/study was related to muscle strength improvement and those who returned were younger and had less time elapsed from trauma. Individual factors and rehabilitation were pointed out as helpful in aiding return to work. Satisfaction with treatment was high. These findings can help to optimize goals in the rehabilitation environment.

Assessment of Motor Repertoire in 3- to 5-Month-Old Infants With Obstetric Brachial Plexus Lesion

PURPOSE

The aim of this study was to define the movement characteristics and postures of infants with obstetric brachial plexus lesion.

METHODS

The study group included 20 infants with obstetric brachial plexus lesion and a control group of 20 infants with normal neurological outcome, aged 9 to 17 weeks postterm. Infants were evaluated by global and detailed general movements assessment.

RESULTS

There were no significant differences between the motor optimality scores of the 2 groups. However, there were some differences in terms of concurrent movements and the posture. Infants with obstetric brachial plexus lesion demonstrated more excitement bursts, head rotation, hand-knee contact, rolling, and few finger posture and postural asymmetry, and performed jerky movements when compared with the control group.

CONCLUSIONS

Obstetric brachial plexus lesion did not affect the quality of fidgety movements of the infants but leads to compensatory movements in concurrent movements on the unaffected sides.

Development of a Questionnaire to Measure Impact and Outcomes of Brachial Plexus Injury

BACKGROUND

The physical and psychological impact of brachial plexus injury (BPI) has not been comprehensively measured with BPI-specific scales. Our objective was to develop and test a patient-derived questionnaire to measure the impact and outcomes of BPI.

METHODS

We developed a questionnaire in 3 phases with preoperative and postoperative patients. Phase 1 included interviews of patients using open-ended questions addressing the impact of BPI and improvement expected (preoperative patients) or received (postoperative patients). Phase 2 involved assembling a draft questionnaire and administering the questionnaire twice to establish test-retest reliability. Phase 3 involved selecting final items, developing a scoring system, and assessing validity. Patient scores using the questionnaire were assessed in comparison with scores of the Disabilities of the Arm, Shoulder and Hand (DASH) and RAND-36 measures.

RESULTS

Patients with partial or complete plexopathy participated. In Phase 1 (23 patients), discrete categories were discerned from open-ended responses and became items for the preoperative and postoperative versions of the questionnaire. In Phase 2 (50 patients [14 from Phase 1]), test-retest reliability was established, with weighted kappa values of ≥0.50 for all items. In Phase 3, 43 items were retained and grouped into 4 subscales: symptoms, limitations, emotion, and improvement expected (preoperative) or improvement received (postoperative). A score for each subscale, ranging from 0 to 100, can be calculated, with higher scores indicating more symptoms, limitations, and emotional distress, and greater improvement expected (or received). Preoperative scores were worse than postoperative scores for the symptoms, limitations, and emotion subscales (composite score of 48 compared with 38; p = 0.05), and more improvement was expected than was received (69 compared with 53; p = 0.01). Correlations with the DASH (0.44 to 0.74) and RAND-36 (0.23 to 0.80) for related scales were consistent and moderate, indicating that the new questionnaire is valid and distinct.

CONCLUSIONS

We developed a patient-derived questionnaire that measures the physical and psychological impact of BPI on preoperative and postoperative patients and the amount of improvement expected or received from surgery. This BPI-specific questionnaire enhances the comprehensive assessment of this population.

Correlation between motor function recovery and daily living activity outcomes after brachial plexus surgery

OBJECTIVE

To establish the correlation between clinical evaluation of motor function recovery and daily living activities in 30 patients with upper traumatic brachial plexus injury submitted to surgery.

METHODS

The score of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and the Louisiana State University Health Sciences Center (LSUHSC) scale were determined in 30 patients. Epidemiologic factors were also examined and correlations were determined.

RESULTS

There was a significant correlation between the clinical evaluation and the daily living activities after a 12-month period (r = 0.479 and p = 0.007). A direct correlation was observed between the functional recovery of the upper limb and the time between injury and surgery (r = 0.554 and p = 0.001). The LSUHSC scores (p = 0.049) and scores from the DASH questionnaire (p = 0.013) were better among patients who returned to work.

CONCLUSIONS

Clinical evaluation and daily living activities in adult patients who underwent nerve transfer after brachial plexus injury showed significant and measurable improvements.
