RESUMEN
BACKGROUND: Neuralgic amyotrophy (NA) is an acute inflammation of nerves within the brachial plexus territory leading to severe pain and multifocal paresis resulting in >60% of patients having residual complaints and functional limitations correlated with scapular dyskinesia. Our primary aim was to compare the effects of multidisciplinary rehabilitation (MR), focused on motor relearning to improve scapular dyskinesia and self-management strategies for reducing pain and fatigue, with usual care (UC) on shoulder, arm and hand functional capability in patients with NA. METHODS: In a non-blinded randomised controlled trial (RCT), patients with NA (aged≥18 years, scapular dyskinesia, >8 weeks after onset) were randomised to either an MR or an UC group. MR consisted of a diagnostic multidisciplinary consultation and eight sessions of physical and occupational therapy. Primary outcome was functional capability of the shoulder, arm and hand assessed with the Shoulder Rating Questionnaire-Dutch Language Version (SRQ-DLV). RESULTS: We included 47 patients with NA; due to drop-out, there were 22 participants in MR and 15 in UC for primary analysis. The mean group difference adjusted for sex, age and SRQ-DLV baseline score was 8.60 (95%CI: 0.26 to 16.94, p=0.044). The proportion attaining a minimal clinically relevant SRQ-DLV improvement (≥12) was larger for the MR group (59%) than the UC group (33%) with a number needed to treat of 4. CONCLUSION: This RCT shows that an MR programme focused on motor relearning to improve scapular dyskinesia, combined with self-management strategies for reducing pain and fatigue, shows more beneficial effects on shoulder, arm and hand functional capability than UC in patients with NA. TRIAL REGISTRATION NUMBER: NCT03441347.

PURPOSE OF REVIEW: This review focuses on the current insights and developments in neuralgic amyotrophy (NA), an auto-immune multifocal peripheral nervous system disorder that leaves many patients permanently impaired if not recognized and treated properly. RECENT FINDINGS: NA is not as rare as previously thought. The phenotype is broad, and recent nerve imaging developments suggest that NA is the most common cause of acute anterior or posterior interosseous nerve palsy. Phrenic nerve involvement occurs in 8% of all NA patients, often with debilitating consequences. Acute phase treatment of NA with steroids or i.v. immunoglobulin may benefit patients. Long-term consequences are the rule, and persisting symptoms are mainly caused by a combination of decreased endurance in the affected nerves and an altered posture and movement pattern, not by the axonal damage itself. Patients benefit from specific rehabilitation treatment. For nerves that do not recover, surgery may be an option. SUMMARY: NA is not uncommon, and has a long-term impact on patients' well-being. Early immunomodulating treatment, and identifying phrenic neuropathy or complete nerve paralysis is important for optimal recovery. For persistent symptoms a specific treatment strategy aiming at regaining an energy balance and well-coordinated scapular movement are paramount.

RESUMEN
BACKGROUND: Strength testing of the serratus anterior muscle with hand held dynamometry (HDD) in supine subjects has low reproducibility, and is influenced by compensatory activity of other muscles like the pectoralis major and upper trapezius. Previously, two manual maximum voluntary isometric contraction tests of the serratus anterior muscle were reported that recruited optimal surface electromyography (sEMG) activity in a sitting position. We adapted three manual muscle tests to make them suitable for HHD and investigated their validity and reliability. METHODS: Twenty-one healthy adults were examined by two assessors in one supine and two seated positions. Each test was repeated twice. Construct validity was determined by evaluating force production (assessed with HHD) in relation to sEMG of the serratus anterior, upper trapezius and pectoralis major muscles, comparing the three test positions. Intra- and interrater reliability were determined by calculating intra-class correlation coefficients (ICC) smallest detectable change (SDC) and standard error of measurement (SEM). RESULTS: Serratus anterior muscle sEMG activity was most isolated in a seated position with the humerus in 90° anteflexion in the scapular plane. This resulted in the lowest measured force levels in this position with a mean force of 296 N (SEM 15.8 N). Intrarater reliability yielded an ICC of 0.658 (95% CI 0.325; 0.846) and an interrater reliability of 0.277 (95% CI -0.089;0.605). SDC was 127 Newton, SEM 45.8 Newton. CONCLUSION: The results indicate that validity for strength testing of the serratus anterior muscle is optimal with subjects in a seated position and the shoulder flexed at 90° in the scapular plane. Intrarater reliability is moderate and interrater reliability of this procedure is poor. However the high SDC values make it difficult to use the measurement in repeated measurements.

PURPOSE: There is lack of knowledge, evidence, and guidelines for rehabilitation interventions for persons with neuralgic amyotrophy (NA) or brachial plexus pathology. A first pilot study, evaluating the effect of an integrated rehabilitation programme, showed improvements in activity and participation levels. AIM: To gain insight, from the perspective of patients and therapists, into the critical ingredients of the programme, that contributed to improvements in activity and participation. MATERIALS AND METHODS: A qualitative study using semi-structured interviews with eight patients and five therapists (three occupational therapists and two physical therapists). Participants were asked to identify and describe factors regarding the rehabilitation that they perceived as positive and aspects of the programme that could be improved. Data were analysed using a constant comparative approach. RESULTS: Patients reported (1) Time to diagnose: "Finally I'm in the right place;" (2) Awareness: "They gave me a mirror;" (3) Partnership: "There was real contact with the therapists; we made decisions together;" (4) Close collaboration: "Overlapping scopes of practice; doing the same from a different perspective;" and finally (5) Self-management: "Now I can do it myself." Therapists reported (1) "Patients knowledge and understanding is critical to success;" (2) "Activate problem solving and decision making;" (3) "Personalize your therapy; it's more than just giving exercises and information;" (4) "Constant consultation within the team; consistency in messages and approach;" and (5)" Ultimately the patient is in charge." CONCLUSIONS: The critical ingredients, correspond well with each other and include a person-centred approach, education, support in problem solving and decision making and an integrated team approach. These ingredients provided the patients with confidence to take responsibility to manage their everyday lives, the ultimate goal of the programme. Implications for rehabilitation Both patients and therapists believe that the ability to self-manage and take control should be the outcome of high quality integrated rehabilitation programmes for patients with neuralgic amyotrophy and/or other brachial plexus injuries. A person-centred, collaborative, and integrated team approach, among all members of the team, are critical components of care delivery in personalised interventions. Critical programme ingredients are knowledge and education of both the patient and therapists; partnership between patient-therapist and within the team; patient activation and self-reflection; and personalised care. Patients recommend more options for personalisation of the intensity and duration of rehabilitation, the possibility to consult a psychologist and peer support within a group setting.

BACKGROUND: Neuralgic Amyotrophy (NA) is characterized by neuropathic pain, subsequent patchy paresis and possible sensory loss in the upper extremity. Many patients experience difficulties in performing activities of daily life and are unable to resume work. We developed a combined physical- and occupational therapy program for patients recovering from NA. OBJECTIVE: Evaluation of the effectiveness of a multidisciplinary intervention program for patients with subacute NA. METHODS: We performed a within subject proof-of-principle pilot study in eight patients with subacute NA. Patients followed 8 hours of physical and 8 hours of occupational therapy spread over a 16-week period. PRIMARY OUTCOME MEASURES: The Canadian Occupational Performance Measure (COPM) and Shoulder Rating Questionnaire (SRQ). SECONDARY OUTCOME MEASURE: Disability of Arm Shoulder and Hand (DASH). RESULTS: Improvements (mean (95% CI)) were found in the performance and satisfaction scores of the COPM +2.3 (0.9-3.7) and +1.4 (0.4-2.4) points, respectively and the SRQ +14.8 (7.4-22.0) points. The majority of patients (6 out of 8) also demonstrated improvements in the DASH. CONCLUSION: The proposed physical and occupational therapy program, may be effective for patients with subacute NA, as demonstrated by improvements in activity, performance and participation.
