To what extent are guidelines used in spasticity clinics? A qualitative study of facilitators and barriers to spasticity guideline implementation.

OBJECTIVE: To determine the common understanding of focal muscle spasticity guidelines amongst clinicians working in spasticity clinics. To examine the facilitators and barriers to their implementation as well as their influence on clinic processes. DESIGN: A qualitative study based on a phenomenological approach. SETTING: Online videoconferencing platform. PARTICIPANTS: Sixteen experienced multi-disciplinary clinicians providing specialised care across 12 spasticity clinics in Victoria, Australia. INTERVENTION: Observational. MAIN MEASURES: Two independent reviewers performed line by line coding of transcripts. Reflexive thematic analysis was undertaken with themes/subthemes inductively derived. RESULTS: Seven key themes emerged. First, knowledge of specific guideline recommendations was low amongst some clinicians. Second, there is a lack of health service resources to support guideline implementation. Third, a limited evidence base for guidelines affected clinicians' willingness to implement the recommendations. Fourth, peer support was highly valued but opportunities to collaborate were limited. Fifth, a large amount of intrinsic motivation and personal time was required from clinicians to successfully implement guideline recommendations. Sixth, the standardisation of clinic processes was one way in which clinicians felt they could better align their clinical practice to guidelines. Lastly, guidelines overall had a moderate influence on spasticity clinic processes. CONCLUSIONS: Knowledge of recommendations varied but, overall, guidelines had an influence on clinic processes and staff perceptions across the state-wide services. Health service resources, limited evidence for guideline recommendations and time constraints were considered barriers to spasticity guideline implementation. Multi-disciplinary expertise and teamwork, the individual's motivation to change and inter-clinic collaboration were considered to be the facilitators.

Reproducibility, Construct Validity, and Responsiveness of the Tetraplegia Upper Limb Activities Questionnaire, TUAQ. Part 2.

OBJECTIVE: To test reliability, construct validity and responsiveness of the Tetraplegia Upper Limb Activities Questionnaire (TUAQ), a patient-reported outcome measure that assesses perceived performance and satisfaction with 10 standardized activities. DESIGN: Outcome measure psychometric evaluation. SETTING: Spinal cord injury units in 2 countries. PARTICIPANTS: Reproducibility: 47 individuals with tetraplegia. Construct validity and responsiveness: 33 individuals with tetraplegia undergoing surgery to restore hand function (N=80). INTERVENTIONS: Reproducibility: The TUAQ was completed on 2 occasions, 2 weeks apart. Construct validity and responsiveness: Participants completed the TUAQ prior to surgery and 3-12 months after hand reconstruction surgery. Internal consistency was examined using Cronbach α. Two agreement parameters were examined: the SEM and minimal detectable change with 90% confidence interval (MDC90). Construct validity was evaluated using Pearson product moment correlation against a priori hypotheses. Responsiveness was assessed using paired t tests and effect size. RESULTS: Test-retest reliability and internal consistency was high (intraclass correlation coefficient of 0.89 for performance scale and 0.88 for satisfaction, Cronbach α of 0.92 and 0.90, respectively). For agreement the SEM scores were 4.7 and 3.5, with MDC90 of 10.9 and 8.2, respectively. Responsiveness and construct validity showed sound results with no ceiling or floor effects and with large effect size (>1.05). CONCLUSIONS: The TUAQ demonstrates good psychometric properties for reliability and agreement for persons with tetraplegia and responsiveness and construct validity for surgical reconstruction of hand function for persons with tetraplegia. The TUAQ appears appropriate to be used as a patient-reported outcome measure for clinical and research purposes in this population.

Development, Internal Construct, and Unidimensionality of the Tetraplegia Upper Limb Activities Questionnaire, TUAQ. Part 1.

OBJECTIVE: This study aims to develop a patient-reported outcome measure that focuses on relevant daily activities relying on upper extremity for individuals with tetraplegia. DESIGN: Cross-sectional study. SETTING: Spinal cord injury units in 2 countries. PARTICIPANTS: Ninety-nine individuals (N=99) with C2-C8, American Spinal Injury Association Impairment Scale A-D tetraplegia, mean age 46 years, 1- 43 years post injury. INTERVENTIONS: Thirteen items included in the initial testing were chosen from 708 activity limitations identified by individuals with tetraplegia. Items were pilot tested for wording, response options, and relevance for both performance and satisfaction. Items were analyzed and reselected using exploratory factor analysis and Rasch analysis for local dependency, dimensionality, differential item functioning (DIF), threshold response, and targeting. MAIN OUTCOME MEASURES: Not applicable. RESULTS: Exploratory factor analysis supported a 2-factor solution for both performance and satisfaction. While data fit the Rasch model, there was evidence of local dependency and multiple disordered thresholds. Three items were removed because of high interitem correlation and DIF and the scale rescored to 5 response options. The remaining 10 items demonstrated fit to the Rasch model, with no local dependency, no multidimensionality, no item or person misfit, and minimal disordered thresholds. CONCLUSIONS: Results support the internal construct validity and unidimensionality of the Tetraplegia Upper Limb Activities Questionnaire (TUAQ), a 10-item, 5-response patient-reported outcome measure assessing performance and satisfaction with activities targeted to the upper extremity for individuals with tetraplegia. Further testing is required and ongoing to evaluate reliability and responsiveness of the TUAQ.

Effective long-term management of brachial plexus injury following surgery: What is needed from hand therapists' perspectives.

INTRODUCTION: Traumatic, brachial plexus injuries (BPI) result represent a significant cost to the individual and society. Recovery involves multiple surgeries, takes years, and often results in permanent physical dysfunction. While the last couple of decades have seen advancements in surgical management, the BPI rehabilitation literature has not kept pace with these developments. PURPOSE: We aim to explore the experience of public and privately employed hand therapists' in delivering effective long-term rehabilitation services to inviduals with BPI in Australia. METHODS: An interpretative qualitative study. Two focus groups were conducted with Australian hand therapists' (n = 10). Data were analyzed using an inductive thematic approach. RESULTS: Three key themes were generated from the data. The first theme 'Falling through the gaps: overlooked components of therapy for BPI' captures participants' thoughts on postinjury health care and rehabilitation services. The second 'Developing a therapeutic alliance: underpinned by time and trust' relates to the relationship building challenges and opportunities following trauma that will withstand the long-term recovery of individuals following BPI. The last theme, 'Factors required for professional development: knowledge and support,' considers the variation seen with these clients in relation to therapy needs and outcomes. CONCLUSIONS: The findings of this study highlight the need to better equip hand therapists' skills and knowledge in responding to pain and psychological management post BPI. Our results reinforce the benefit of interdisciplinary models of care in the management of individuals with BPI.

Expanding traditional tendon-based techniques with nerve transfers for the restoration of upper limb function in tetraplegia: a prospective case series.

BACKGROUND: Loss of upper extremity function after cervical spinal cord injury greatly affects independence, including social, vocational, and community engagement. Nerve transfer surgery offers an exciting new option for the reanimation of upper limb function in tetraplegia. The aim of this study was to evaluate the outcomes of nerve transfer surgery used for the reanimation of upper limb function in tetraplegia. METHODS: In this prospective case series, we consecutively recruited people of any age with early (<18 months post-injury) cervical spinal cord injury of motor level C5 and below, who had been referred to a single centre for upper extremity reanimation and were deemed suitable for nerve transfer. All participants underwent single or multiple nerve transfers in one or both upper limbs, sometimes combined with tendon transfers, for restoration of elbow extension, grasp, pinch, and hand opening. Participants were assessed at 12 months and 24 months post-surgery. Primary outcome measures were the action research arm test (ARAT), grasp release test (GRT), and spinal cord independence measure (SCIM). FINDINGS: Between April 14, 2014, and Nov 22, 2018, we recruited 16 participants (27 limbs) with traumatic spinal cord injury, among whom 59 nerve transfers were done. In ten participants (12 limbs), nerve transfers were combined with tendon transfers. 24-month follow-up data were unavailable for three patients (five limbs). At 24 months, significant improvements from baseline in median ARAT total score (34·0 [IQR 24·0-38·3] at 24 months vs 16·5 [12·0-22·0] at baseline, p<0·0001) and GRT total score (125·2 [65·1-154·4] vs 35·0 [21·0-52·3], p<0·0001) were observed. Mean total SCIM score and mobility in the room and toilet SCIM score improved by more than the minimal detectable change and the minimal clinically important difference, and the mean self-care SCIM score improved by more than the minimal detectable change between baseline and 24 months. Median Medical Research Council strength grades were 3 (IQR 2-3) for triceps and 4 (IQR 4-4) for digital extensor muscles after 24 months. Mean grasp strength at 24 months was 3·2 kg (SD 1·5) in participants who underwent distal nerve transfers (n=5), 2·8 kg (3·2) in those who had proximal nerve transfers (n=9), and 3·9 kg (2·4) in those who had tendon transfers (n=8). There were six adverse events related to the surgery, none of which had any ongoing functional consequences. INTERPRETATION: Early nerve transfer surgery is a safe and effective addition to surgical techniques for upper limb reanimation in tetraplegia. Nerve transfers can lead to significant functional improvement and can be successfully combined with tendon transfers to maximise functional benefits.

Validation of a clinical prediction rule for ambulation outcome after non-traumatic spinal cord injury.

STUDY DESIGN: Prospective cohort study. OBJECTIVES: To validate a Clinical Prediction Rule (CPR) for ambulation in a non-traumatic spinal cord injury population (NTSCI). SETTING: Tertiary spinal rehabilitation inpatient service, Melbourne, Australia. METHODS: Adults with confirmed NTSCI were recruited between April 2013 and July 2017. Data based on the original van Middendorp CPR (age and four neurological variables) were collected from participant's medical records and by interview. The Spinal Cord Independence Measure item 12 was used to quantify the ability to walk at 6 and 12 months. A receiver operator curve (ROC) was utilised to determine the performance of the CPR. Ambulatory outcomes were compared for AIS A, B, C and D and aetiology groups. RESULTS: The area under the ROC curve (AUC) was 0.94 with 95% confidence interval (CI) 0.86-1.0 (n = 52). Overall accuracy was 75% at 6 months and 82% at 12 months. For the whole cohort the sensitivity at 12 months was 95% and specificity 73%. However, specificity for AIS C and D was only 50%. CONCLUSION: The CPR correctly predicted those who did not walk at 6 and 12 months following NTSCI, but was less accurate in predicting those who would walk particularly those with an AIS C or D classification. This CPR may be useful to inform planning for future care in individuals with NTSCI, particularly for those who are not expected to walk. Further research with larger sample sizes is required to determine if the trends identified in this study are generalisable.

Psychometric Evaluation of the Brachial Assessment Tool Part 1: Reproducibility.

OBJECTIVE: To evaluate reproducibility (reliability and agreement) of the Brachial Assessment Tool (BrAT), a new patient-reported outcome measure for adults with traumatic brachial plexus injury (BPI). DESIGN: Prospective repeated-measure design. SETTING: Outpatient clinics. PARTICIPANTS: Adults with confirmed traumatic BPI (N=43; age range, 19-82y). INTERVENTIONS: People with BPI completed the 31-item 4-response BrAT twice, 2 weeks apart. Results for the 3 subscales and summed score were compared at time 1 and time 2 to determine reliability, including systematic differences using paired t tests, test retest using intraclass correlation coefficient model 1,1 (ICC1,1), and internal consistency using Cronbach α. Agreement parameters included standard error of measurement, minimal detectable change, and limits of agreement. MAIN OUTCOME MEASURE: BrAT. RESULTS: Test-retest reliability was excellent (ICC1,1=.90-.97). Internal consistency was high (Cronbach α=.90-.98). Measurement error was relatively low (standard error of measurement range, 3.1-8.8). A change of >4 for subscale 1, >6 for subscale 2, >4 for subscale 3, and >10 for the summed score is indicative of change over and above measurement error. Limits of agreement ranged from ±4.4 (subscale 3) to 11.61 (summed score). CONCLUSIONS: These findings support the use of the BrAT as a reproducible patient-reported outcome measure for adults with traumatic BPI with evidence of appropriate reliability and agreement for both individual and group comparisons. Further psychometric testing is required to establish the construct validity and responsiveness of the BrAT.

Preliminary Psychometric Evaluation of the Brachial Assessment Tool Part 2: Construct Validity and Responsiveness.

OBJECTIVES: To evaluate construct validity and responsiveness of the Brachial Assessment Tool (BrAT), a new patient-reported outcome measure for people with traumatic brachial plexus injury (BPI), and to compare it to the Disabilities of the Arm, Shoulder and Hand (DASH) and the Upper Extremity Functional Index (UEFI). DESIGN: Cross-sectional study. SETTING: Outpatient clinics. PARTICIPANTS: Adults (N=29; age range, 20-69y) with confirmed traumatic BPI. INTERVENTIONS: Participants completed the BrAT 3 times over an 18-month period together with 16 DASH activity items and the UEFI. Evaluations were undertaken of construct validity, known-groups validity, 1-way repeated analysis of variance, and effect size. MAIN OUTCOME MEASURES: BrAT, DASH, and UEFI. RESULTS: The BrAT demonstrated a moderate to low correlation with the DASH activity items (<0.7) and a large correlation with the UEFI (>0.7). According to known-groups validity, only the BrAT was able to discriminate between people who stated they could use their hand versus those who were unable to use their hand to perform activities. All measures indicated a significant effect for time with the exception of BrAT subscale 1. The effect size was highest for the BrAT but lower than expected (BrAT, .52-.40; DASH, .15; UEFI, .36). CONCLUSIONS: These preliminary findings support the BrAT as a valid and responsive patient-reported outcome measure for adults with traumatic BPI. The BrAT activity items appear to be more targeted than the DASH or UEFI particularly for people with more severe BPI. The BrAT also appears to be measuring a different activity construct than the DASH and the UEFI. Further work is required to confirm these results with larger sample sizes.

Evaluation of Internal Construct Validity and Unidimensionality of the Brachial Assessment Tool, A Patient-Reported Outcome Measure for Brachial Plexus Injury.

OBJECTIVE: To evaluate the internal construct validity and dimensionality of a new patient-reported outcome measure for people with traumatic brachial plexus injury (BPI) based on the International Classification of Functioning, Disability and Health definition of activity. DESIGN: Cross-sectional study. SETTING: Outpatient clinics. PARTICIPANTS: Adults (age range, 18-82y) with a traumatic BPI (N=106). INTERVENTIONS: There were 106 people with BPI who completed a 51-item 5-response questionnaire. Responses were analyzed in 4 phases (missing responses, item correlations, exploratory factor analysis, and Rasch analysis) to evaluate the properties of fit to the Rasch model, threshold response, local dependency, dimensionality, differential item functioning, and targeting. MAIN OUTCOME MEASURES: Not applicable, as this study addresses the development of an outcome measure. RESULTS: Six items were deleted for missing responses, and 10 were deleted for high interitem correlations >.81. The remaining 35 items, while demonstrating fit to the Rasch model, showed evidence of local dependency and multidimensionality. Items were divided into 3 subscales: dressing and grooming (8 items), arm and hand (17 items), and no hand (6 items). All 3 subscales demonstrated fit to the model with no local dependency, minimal disordered thresholds, no unidimensionality or differential item functioning for age, time postinjury, or self-selected dominance. Subscales were combined into 3 subtests and demonstrated fit to the model, no misfit, and unidimensionality, allowing calculation of a summary score. CONCLUSIONS: This preliminary analysis supports the internal construct validity of the Brachial Assessment Tool, a unidimensional targeted 4-response patient-reported outcome measure designed to solely assess activity after traumatic BPI regardless of level of injury, age at recruitment, premorbid limb dominance, and time postinjury. Further examination is required to determine test-retest reliability and responsiveness.

Assessment of the internal construct validity of the revised High-Level Mobility Assessment Tool for traumatic orthopaedic injuries.

OBJECTIVE: To determine whether the revised High-Level Mobility Assessment Tool (HiMAT) was valid for measuring mobility for people with multi-trauma orthopaedic lower limb injuries. DESIGN: Cross-sectional study. SUBJECTS: Participants with lower limb multi-trauma orthopaedic injuries. METHODS: One complete revised HiMAT was obtained for 106 people within 12 weeks of being allowed to fully weight bear. Rasch analysis was used to assess the overall fit of the model for individuals and items, differential item functioning, local dependency, targeting of items and dimensionality. RESULTS: The mean revised HiMAT score was 10.5 (SD = 6.8) with a range of 5-30. Rasch analysis of revised HiMAT showed adequate overall fit to the model (P = 0.29) with no misfitting items (fit residual SD = 0.69) or persons (fit residual SD = 0.62). The scale showed good internal consistency (Person Separation Index = 0.91). One item (hopping) demonstrated disordered thresholds, however this item had good fit to the model in all other aspects. The revised HiMAT was unidimensional, and no differential item functioning was detected for gender or age. The revised HiMAT was well targeted for this group with a range of items across all ability levels. CONCLUSION: The results of this study support the internal construct validity of the revised HiMAT as a well-targeted, unidimensional measure of high-level mobility with no ceiling or floor effect for males and females recovering from multi-trauma orthopaedic lower limb injuries.

Translation and internal content validation of the Swedish version of the Brachial Assessment Tool (BrAT).

PURPOSE: To translate and culturally adapt the Brachial Assessment Tool (BrAT) into Swedish and evaluate the internal consistency, and internal content validity using Rasch analysis in patients with traumatic brachial plexus injuries (TBPI). METHODS: The translation was made in accordance with international guidelines. TBPI patients were identified in clinical records. The BrAT-Swe was sent out to patients by post. Internal consistency was assessed using Cronbach alpha and content validity using Rasch analysis evaluating fit to the Rasch model, threshold response, local dependency, dimensionality, differential item functioning (DIF), and targeting. RESULTS: The translation of the BrAT was completed without major discrepancies. A total of 164 patients completed the BrAT-Swe. Internal consistency ranged from 0.90 to 0.98. Rasch analysis supported the content validity. All subscales demonstrated fit to the model with no local dependency, minimal disordered thresholds and no unidimensionality. Uniform DIF for item 6 by age, was identified. Minimal differences in hierarchical ordering were identified. CONCLUSIONS: This study presents a Swedish translation of the BrAT (BrAT-Swe) and has demonstrated that the translated BrAT-Swe is well adapted for Swedish circumstances. Analysis supports the internal content validity of the BrAT-Swe as a unidimensional targeted PROM designed to assess activity limitation after TBPI.

The Swedish translation of the Brachial Assessment Tool (BrAT), the BrAT-Swe, is a valid instrument that can be used in a Swedish context.The BrAT-Swe subscales can be used independently or as a total score, similar to the original BrAT.The BrAT-Swe may be used to guide rehabilitation and for goal setting for patients with traumatic 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.

The Brachial Assessment Tool (BrAT) has been cross-cultural translated into DanishBrAT(DK) shows adequate content validity for activity limitation in adults with traumatic brachial plexus injuryBrAT(DK) is a reliable measure, with a smallest detectable change of 16.01 points for the total scaleWe recommend the use of BrAT(DK) in clinical practice to inform goal setting and future interventions and treatment evaluations.

Effectiveness of Pilates exercise in treating people with chronic low back pain: a systematic review of systematic reviews.

BACKGROUND: Systematic reviews provide clinical practice recommendations that are based on evaluation of primary evidence. When systematic reviews with the same aims have different conclusions, it is difficult to ascertain which review reported the most credible and robust findings. METHODS: This study examined five systematic reviews that have investigated the effectiveness of Pilates exercise in people with chronic low back pain. A four-stage process was used to interpret findings of the reviews. This process included comparison of research questions, included primary studies, and the level and quality of evidence of systematic reviews. Two independent reviewers assessed the level of evidence and the methodological quality of systematic reviews, using the National Health and Medical Research Council hierarchy of evidence, and the Revised Assessment of Multiple Systematic Reviews respectively. Any disagreements were resolved by a third researcher. RESULTS: A high level of consensus was achieved between the reviewers. Conflicting findings were reported by the five systematic reviews regarding the effectiveness of Pilates in reducing pain and disability in people with chronic low back pain. Authors of the systematic reviews included primary studies that did not match their questions in relation to treatment or population characteristics. A total of ten primary studies were identified across five systematic reviews. Only two of the primary studies were included in all of the reviews due to different inclusion criteria relating to publication date and status, definition of Pilates, and methodological quality. The level of evidence of reviews was low due to the methodological design of the primary studies. The methodological quality of reviews varied. Those which conducted a meta-analysis obtained higher scores. CONCLUSION: There is inconclusive evidence that Pilates is effective in reducing pain and disability in people with chronic low back pain. This is due to the small number and poor methodological quality of primary studies. The Revised Assessment of Multiple Systematic Reviews provides a useful method of appraising the methodological quality of systematic reviews. Individual item scores, however, should be examined in addition to total scores, so that significant methodological flaws of systematic reviews are not missed, and results are interpreted appropriately.

Internal validity of the revised HiMAT for people with neurological conditions.

OBJECTIVE: The High-level Mobility Assessment Tool (HiMAT) was developed to measure high-level mobility limitations following traumatic brain injury. The aim of this study was to investigate if the revised HiMAT is valid for use with adults with neurological conditions other than traumatic brain injury. DESIGN: Cross-sectional study. SUBJECTS: Ninety-five participants with neurological conditions. METHODS: HiMAT score sheets were retrieved from the central medical files of people who had attended a major rehabilitation facility for a neurological condition from January 2006 to October 2007. Additional HiMAT score sheets were submitted by therapists who participated in the HiMAT User's Group. Rasch analysis (RUMM2030 software) was used to determine the overall fit of the model, individual item fit and differential item functioning. RESULTS: Rasch analysis supported the internal validity of the revised eight-item HiMAT for individuals with neurological conditions. It showed good overall fit (P = 0.74), no misfitting items and excellent internal consistency (Person Separation Index = 0.91). The HiMAT is unidimensional with no evidence of response dependency and no differential item functioning for age or sex. CONCLUSION: Further development of the revised HiMAT is required to investigate other aspects of validity, reliability and responsiveness in different neurological populations. However, the results support the internal validity of the revised HiMAT when used for people with neurological conditions who are able to walk without gait aids.

Construct Validity of the Revised High-Level Mobility Assessment Tool for Children Who Are Developing Typically.

OBJECTIVE: The aim of this project was to evaluate the construct validity of the high-level mobility assessment tool (HiMAT) for children who are developing typically with no underlying condition that may affect mobility. METHODS: The HiMAT is a revised 8-item measure of high-level mobility. Rasch analysis was used to assess fit to the Rasch model indicating unidimensionality, person separation index local dependency, targeting of items, and differential item functioning. RESULTS: Children with typical development aged 5 to 12 years (n = 1091; 554 girls and 537 boys) were recruited from 8 schools. The mean HiMAT score was 22.4/32 (range, 8-32). Data fit the Rasch model, indicating that the HiMAT was a unidimensional scale assessing a single construct (high-level mobility). The person separation index was .86, indicating good reliability. The skip item exhibited differential item functioning by sex. Although items were well targeted, the fit residual mean for persons was 2.40, indicating most found the tasks easy to complete. Unlike in adult populations, 2 items (walk and walk over obstacle) exhibited local dependency >0.2. CONCLUSION: The HiMAT is a unidimensional targeted performance measure of high-level mobility for children with typical development aged 5 to 12 years. Further examination of the relationship between the test items "walk" and "walk over an obstacle" may be required to ensure that scores on these items are truly independent of one another.

Predicting strength outcomes for upper limb nerve transfer surgery in tetraplegia.

We report a retrospective study of 112 nerve transfers in 39 participants to investigate predictors of strength outcomes after nerve transfer surgery for upper limb reanimation in tetraplegia. We measured clinical and pre- and intraoperative neurophysiological assessment variables and compared them with strength outcomes 2 years after nerve transfer surgery. We found statistically significant improvement in Medical Research Council strength grades after nerve transfer surgery with lower cervical spine injuries (between one and two grades), lower donor nerve stimulation thresholds (half of a grade), greater motor evoked potential activity in recipient nerves (half of a grade) and greater muscle responses to intraoperative stimulation of donor (half of a grade) and recipient nerves (half of a grade).Level of evidence: III.

Do randomised controlled trials evaluating functional outcomes following botulinum neurotoxin-A align with focal spasticity guidelines? A systematic review.

PURPOSE: The impact of botulinum neurotoxin-A (BoNT-A) on functional outcomes when managing focal muscle spasticity remains unclear. It is possible that randomised controlled trial (RCT) design and/or reporting may be a contributing factor. The objective of this review was to determine the extent to which RCTs evaluating functional outcomes following BoNT-A align with focal spasticity guidelines. MATERIALS AND METHODS: RCTs published from 2010 were included if they targeted focal spasticity, included BoNT-A, randomised a physical intervention to the upper/lower limb, or the primary outcome(s) related to the activity/participation domains of the International Classification of Functioning, Disability, and Health. Data extraction and quality appraisal using the Modified PEDro and Modified McMasters Tool were performed independently by two reviewers. General research practices were also extracted such as compliance with therapy reporting guidelines. RESULTS: Fifty-two RCTs were eligible. Individualised goal setting was uncommon (25%). Six studies (11.5%) included multi-disciplinary management, and five (9.6%) included patient/caregiver education. Four studies (7.7%) measured outcomes beyond 6 months. The Median Modified PEDro score was 11/15. CONCLUSIONS: Alignment with focal spasticity guidelines in RCTs was generally low. Our understanding of the impact of focal spasticity management on functional outcomes may be improved if RCT design aligned more closely with guideline recommendations.IMPLICATIONS FOR REHABILITATIONThe influence of BoNT-A on improved functional outcomes is yet to be determined.Individualised goal setting with a multi-disciplinary team is uncommon in an RCT design, despite it being a key guideline recommendation.Given the long-term nature of spasticity management, guidelines recommend short as well as long-term reviews following intervention however RCTs rarely assess beyond 6 months.

A synthesis and appraisal of clinical practice guidelines, consensus statements and Cochrane systematic reviews for the management of focal spasticity in adults and children.

OBJECTIVE: To identify and appraise the existing clinical practice guidelines, consensus statements and Cochrane systematic reviews for the management of adult and paediatric focal spasticity to generate a single synthesized guideline. METHODS: Systematic review of 12 electronic databases. Clinical practice guidelines, consensus statements and Cochrane systematic reviews for focal spasticity in adults and children. Included studies were appraised according to the AGREE II criteria. RESULTS: A total of 25 papers were included in this review, comprising 12 clinical practice guidelines, nine consensus statements and four Cochrane systematic reviews. The areas most strongly endorsed were: (1) management to be provided by a multi-disciplinary team, (2) therapy should be goal-directed, (3) goals to be developed in conjunction with the patient and family, and (4) importance of follow-up evaluations. There was a greater focus on activity outcomes and classification in the paediatric papers. The guidelines varied considerably in their quality, with AGREE II scores ranging from 52.8 to 97.1%. CONCLUSIONS: This systematic review has synthesized the key elements regarding principles of focal spasticity management, outcome measures, physical interventions and educational recommendations into a single, readily applied guideline available for clinical use. Despite considerable variability in the quality of the guidelines, several strong themes emerged.Implications for rehabilitationFocal spasticity management should be multi-disciplinary, patient-centred and goal-directed.Routine measurement of impairment and activity are strongly endorsed.Botulinum toxin A injection should only be provided as part of an integrated approach to focal spasticity management.

Clinimetric evaluation of questionnaires used to assess activity after traumatic brachial plexus injury in adults: a systematic review.

OBJECTIVES: To identify upper limb questionnaires used in the brachial plexus injury (BPI) literature to assess activities and to evaluate their clinimetric properties. DATA SOURCES; STUDY SELECTION; DATA EXTRACTION: This systematic review was undertaken in 2 stages. In stage 1, 10 electronic databases and 1 Internet journal were searched for quantitative studies (ie, randomized controlled trials, comparative studies, case series, and case studies) that evaluated outcome after BPI, irrespective of language or date of publication, from date of database inception to September 2010. All outcome instruments used were extracted and classified using the International Classification of Functioning, Disability and Health framework. Questionnaires were identified that apportioned >50% of the total score to the assessment of upper limb activity. In stage 2, 4 electronic databases were searched for papers that evaluated the clinimetric properties of all identified activity questionnaires with respect to peripheral nerve injuries of the upper limb. Two independent reviewers assessed the clinimetric properties of identified questionnaires according to standardized criteria. DATA SYNTHESIS: Stage 1 identified 4324 papers, of which 265 met the inclusion criteria. One hundred and three outcome measures were identified, the majority of which assess body function or body structure. Twenty-nine questionnaires assessed upper limb activity. Two questionnaires, the ABILHAND and Disability of the Arm, Shoulder and Hand (DASH), attributed >50% of the overall score to activity of the upper limb. The DASH had some published evidence of clinimetric properties in individuals with peripheral nerve injuries. Neither had been clinimetrically evaluated for BPI, nor met all quality criteria. CONCLUSIONS: Day-to-day activities of the upper limb are infrequently evaluated after BPI. While attempts have been made to measure activity, there is a paucity of clinimetric evidence on activity questionnaires for individuals with BPI. We recommend that a core set of items be developed which evaluate activity, as well a body structure, body function, and participation.
