Three-Dimensional Upper Limb Movement Analysis in Children and Adolescents With Brachial Plexus Birth Injury: A Systematic Review.

BACKGROUND: To synthesize the current evidence on clinical use of three-dimensional upper limb movement analysis (3D-ULMA) in children and adolescents with brachial plexus birth injury (BPBI). METHODS: MEDLINE, Embase, and Web of Science were searched for relevant studies up to April 2022. An automatic e-mail alert was installed to ensure no eligible article was missed. Articles evaluating 3D-ULMA in children and adolescents with BPBI were included. Covidence web-based platform was used for blind screening of eligible articles. Twenty-one observational studies with a final sample size of 609, encompassing 493 BPBI cases, met the inclusion criteria. Data were extracted using a custom form to support standardized extraction conforming to the Cochrane Checklist of items. Risk of bias was assessed using the Newcastle-Ottawa Scale, the Strengthening the Reporting of Observational Studies in Epidemiology checklist, and a specifically established quality assessment form for kinematic analysis studies. RESULTS: Study setups differed, including six different types of kinematic devices. Twelve studies used the (modified) Mallet positions for their 3D-ULMA. Throughout the studies, 3D-ULMA was used for various purposes. The Newcastle-Ottawa Scale scored 16 articles with five stars or more, indicating fair to moderate quality. CONCLUSIONS: This systematic review summarizes the different 3D-ULMA kinematic devices, test protocols, and their clinical use for BPBI. The use of 3D-ULMA provides valuable, objective, and quantified data to clinicians with regard to movement strategies; it complements existing clinical scales and can be implemented to evaluate effectiveness of therapy interventions. Implications for future research and clinical practice are discussed.

Subacute Brachial Plexopathy due to Intraneural Epithelioid Hemangioma: A Case Report.

Brachial plexopathy is a common consideration in the differential diagnosis of upper extremity sensory and motor deficits, and neoplasms signify one possible etiology of brachial plexopathy. Of the neoplastic brachial plexopathies, hemangiomas involving the brachial plexus are rare. Most reported cases describe extraneural brachial plexus hemangiomas that present as a palpable, tender neck mass associated with pain and sensory disturbance, with minimal motor deficits. Here we share the case of a 48 year-old man with intraneural epithelioid hemangioma of the brachial plexus who presented with prominent motor weakness and no palpable mass. The patient presented with subacute onset of left arm pain, numbness and progressive weakness. Neurologic exam revealed lower motor neuron signs and weakness spanning multiple nerve root and peripheral nerve distributions. Dedicated brachial plexus MRI showed two mass lesions involving the cords of the brachial plexus, with corresponding FDG-avidity on PET/CT. Biopsy revealed intraneural atypical epithelioid hemangioma. After nerve transfer surgery, he had moderate improvement in left arm strength. This case serves to: emphasize the importance of both clinical localization and dedicated brachial plexus imaging in the evaluation of brachial plexopathy; introduce to the literature a new clinical presentation of brachial plexus hemangiomas; encourage consideration of neoplastic brachial plexopathy even when faced with an illness script resembling Parsonage-Turner Syndrome, to avoid delays in diagnosis and treatment.

Brachial Plexus Birth Injury: A Single-Center Study.

Infants can sustain traction injury to brachial plexus nerves during birth, called brachial plexus birth injury (BPBI). While spontaneous recovery is possible, upper extremity weakness can linger. We report our experience at a brachial plexus clinic from a retrospective chart review of infants with BPBI from September 2017 to September 2019. We determined Narakas Classification (NC) and Active Movement Scale (AMS) at predetermined follow-up points. Of 15 patients, 8 presented with NC-I, 5 with NC-II, and 2 with NC-III without Horner's syndrome. By 7 months, 3 had spontaneous recovery, and 4 achieved all and another 4 achieved most AMS5-7 scores. Eleven patients undergoing surgery had little-to-no improvement of shoulder abduction and shoulder external rotation AMS categories by 6 months. Our small sample size prevents us from making definitive conclusions but gave beneficial insight into our clinic barriers to follow-up, data collection, and collaboration with physical and occupational therapy.

Prevalence and risk factors for nerve injury following shoulder dislocation.

BACKGROUND: The glenohumeral joint dislocation can be associated with major nerve injury. The reported prevalence and risk factors for major nerve injury are variable and this injury can have a severe and life-long impact on the patient. The objectives of this study were to analyse the prevalence of major nerve injury following shoulder dislocation and examine risk factors. Management and outcomes of nerve injury were explored. METHODS: A 1 year retrospective cohort study of 243 consecutive adults who presented with a shoulder dislocation was performed. Data were collected on patient demographics, timings of investigations, treatment, follow-up, and nerve injury prevalence and management. The primary outcome measure was prevalence of nerve injury. Risk factors for this were analysed using appropriate tests with Stata SE15.1. RESULTS: Of 243 patients with shoulder dislocation, 14 (6%) had neurological deficit. Primary dislocation (p = 0.004) and older age (p = 0.02) were significantly associated with major nerve injury. Sex, time to successful reduction and force of injury were not associated with major nerve injury in this cohort. Patients with nerve injury made functional recovery to varying degrees. Recurrent shoulder dislocation was common accounting for 133/243 (55%) attendances. CONCLUSIONS: Shoulder dislocation requires careful assessment and timely management in the ED. A 6% rate of nerve injury following shoulder dislocation was at the lower border of reported rates (5-55%), and primary dislocation and older age were identified as risk factors for nerve injury. We emphasise the importance of referring patients with suspected major nerve injury to specialist services.

Diagnostic accuracy of magnetic resonance imaging for nerve injury in obstetric brachial plexus injury: protocol for systematic review and meta-analysis.

BACKGROUND: Early and accurate clinical diagnosis of the extent of obstetric brachial plexus injury (OBPI) is challenging. The current gold standard for delineating the nerve injury is surgical exploration, and synchronous reconstruction is performed if indicated. Magnetic resonance imaging (MRI) is a non-invasive method of assessing the anatomy and severity of nerve injury in OBPI but the diagnostic accuracy is unclear. The primary objective of this review is to determine the diagnostic accuracy of MRI in comparison to surgical brachial plexus exploration for detecting root avulsion in children under 5 with OBPI. The secondary objectives are to determine its' diagnostic accuracy for detecting nerve abnormality and detecting pseudomeningocele(s) in this group. METHODS: This review will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA).We will include studies reporting the accuracy of MRI (index test) compared to surgical exploration (reference standard) in detecting any of the three target conditions (root avulsion, any nerve abnormality and pseudomeningocele) in children under five with OBPI. Case reports and studies where the number of true positives, false positives, true negatives and false negatives cannot be derived will be excluded. We plan to search PubMed, Embase and CENTRAL for relevant studies from database inception to 15 June 2022. We will also search grey literature (medRxiv, bioRxiv and Google Scholar) and perform forward and backward citation chasing. Screening and full-text assessment of eligibility will be conducted by two independent reviewers, who will then both extract the relevant data. The QUADAS-2 tool will be used to assess methodological quality and risk of bias of included studies by two reviewers independently. The following test characteristics for the target conditions will be extracted: true positives, false positives, true negatives and false negatives. Estimates of sensitivity and specificity with 95% confidence intervals will be shown in forest plots for each study. If appropriate, summary sensitivities and specificities for target conditions will be obtained via meta-analyses using a bivariate model. DISCUSSION: This study will aim to clarify the diagnostic accuracy of MRI for detecting nerve injury in OBPI and define its clinical role. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42021267629.

The Relationship Between Patient Factors and Clinical Outcomes of Free Functional Muscle Transfer in Patients with Complete Traumatic Brachial Plexus Injury.

Purpose: Traumatic brachial plexus injury (TBPI) causes severe disabilities to the patients, affecting not only upper limb function but also the psychosocial and economic aspects. Free functional muscle transfer (FFMT) is one of the reconstruction modalities for the management of TBPI. The aim of this study is to evaluate the functional outcomes and their correlation to patient factors. Patients and Methods: This is a retrospective study of 131 patients who suffered from complete TBPI (C5-T1) and were treated with the FFMT procedure to restore elbow flexion and wrist extension from 2010 to 2018 in our institution. We evaluated the active range of motion (AROM), muscle power with MRC (Medical Research Council) scale, DASH score, and complications, with a minimum of 12-month follow-up. Results: Following FFMT surgery, elbow flexion was significantly and successfully restored (MRC ≥ 3) in 75.5% of patients with an average AROM of 88.17 ± 41.29°. The wrist extension was restored in 42% of the patients with an average AROM of 20.69 ± 18.72°. There was no correlation between age, side of injury, and time to surgery with the functional outcomes. There was a weak correlation between education level, rehabilitation compliance, and elbow functional outcomes. Conclusion: FFMT is a reliable surgical option to restore elbow flexion in TBPI with a high satisfactory result. Our findings suggested that the FFMT indication is potentially expanded regardless of the patient factors.

Traumatic Bilateral Brachial Plexus Injury.

Traumatic brachial plexus injuries are serious, life-changing injuries that are becoming more common worldwide. A thorough physical examination, as well as radiologic and electrodiagnostic tests, are all part of the initial evaluation. Parameters such as injury patterns, the timing of intervention, patients' expectations, and pre-injury functional level should always be considered. A bilateral brachial plexus injury is a very uncommon occurrence. To our knowledge, only one case of a bilateral brachial plexus injury associated with trauma has been published in recent literature. We present a rare case of a 19-year-old man who sustained a bilateral brachial plexus injury after a motorbike accident. The patient underwent exploration of the left brachial plexus and a modified Oberlin procedure on his left arm. The right plexus injury was managed conservatively. After a follow-up period of 12 months, the patient completely returned to his previous functional level.

Neuromuscular complications of severe COVID-19 in paediatric patients: Medium-term follow-up.

Neuromuscular complications in paediatric patients with severe coronavirus disease 2019 (COVID-19) are poorly characterised. However, adult patients with severe COVID-19 reportedly present with frequent neuromuscular complications that mainly include critical illness polyneuropathy (CIP), critical illness myopathy (CIM), and focal neuropathies. We examined the records of all paediatric patients with severe COVID-19 who were mechanically ventilated and experienced neuromuscular complications from our single tertiary centre between March 2020 and August 2021. During this period, 4/36 (11%) patients admitted to the paediatric ICU who were mechanically ventilated experienced neuromuscular complications (one CIM, two focal neuropathies, and one CIP associated with plexopathy). In three of them, the gamma genetic variant of SARS-CoV-2 was identified. At the 4-5 month follow-up, three of our patients exhibited slight clinical improvement. We conclude that paediatric patients with severe COVID-19 may present neuromuscular complications similar to adults (11%), and their medium-term prognosis seems unfavourable.

The humeral suspension technique: a novel operation for deltoid paralysis.

Isolated deltoid paralysis is a rare pathology that can occur after axillary nerve injury due to shoulder trauma or infection. This condition leads to loss of deltoid function that can cause glenohumeral instability and inferior subluxation, resulting in rotator cuff muscle fatigue and pain. To establish dynamic glenohumeral stability, a novel technique was invented. Humeral suspension is achieved using a double button implant with non-resorbable high strength cords between the acromion and humeral head. This novel technique was used in two patients with isolated deltoid paralysis due to axillary nerve injury. The results indicate that the humeral suspension technique is a method that supports centralizing the humeral head and simultaneously dynamically stabilizes the glenohumeral joint. This approach yielded high patient satisfaction and reduced pain. Glenohumeral alignment was improved and remained intact 5 years postoperative. The humeral suspension technique is a promising surgical method for subluxated glenohumeral joint instability due to isolated deltoid paralysis.

Surgical Soft Tissue Management for Glenohumeral Deformity and Contractures in Brachial Plexus Birth Injury : A Systematic Review and Meta-analysis.

PURPOSE OF THE REVIEW: Consensus on the effects of soft tissue surgical intervention in the management of brachial plexus birth injury (BPBI) sequalae is lacking. The purpose of this review is to examine the available literature on the functional and structural outcomes following soft tissue surgical management of BPBI sequalae. RECENT FINDINGS: EMBASE, PubMed, and MEDLINE were searched for related literature from the point of database inception until April 2021. Relevant papers were screened by two reviewers independently and in duplicate. A meta-analysis was performed using a random effects model. A total of 25 studies (852 patients) were included in the review, with the number included in each meta-analysis varying based on outcome of interest. There were significant improvements from pre- to post-operative time points for the following measures: Mallet aggregate scores (5.0 points, p<0.0001), active external rotation in adduction (48.9°, p=0.003), passive external rotation in adduction (64.6°, p< 0.00001), active abduction (46.2°, p<0.00001), glenoid version (14.4°, p< 0.00001), and percentage of the humeral head anterior to the scapular line (17.53°, p< 0.00001). Furthermore, data revealed an overall complication rate of 9.3% (79/852 patients) and a major complication rate of 0.47% (4/852 patients). Patients with BPBI sequela experience statistically significant improvements in functional, structural, and range of motion outcomes of the GH joint following soft tissue surgical management. Understanding the ideal indications for each procedure and age of surgical management with future prospective studies will help to optimize surgical management of these patients.

Evaluation of Long-Term Results of Oberlin Surgery in Obstetric Brachial Paralysis.

Objective To evaluate elbow flexion in children with obstetric brachial plexus paralysis submitted to Oberlin transfer. Methods Retrospective study with 11 patients affected by paralysis due to labor who did not present spontaneous recovery from elbow flexion until 12 months of life, operated between 2010 and 2018. Results The children were operated between 5 and 12 months of life, with a mean of 7.9 months, and the mean follow-up time was 133.2 months, ranging from 37 to 238 months. Six patients (54.5%) presented a degree of muscle strength ≥ 3, measured by the strength scale of the Medical Research Council (MRC) and, according to the active movement scale (AMS), 5 patients obtained a score of ≥ 5. A negative correlation was identified between the AMS and the Narakas classification (r = -0.509), as well as between the strength scale (MRC) and the Narakas classification (r = -0.495). A strong positive correlation was observed (r = 0.935) between the AMS and the MRC demonstrating that the higher the score on the movement scale, the higher the score on the muscle strength scale. Conclusion The Oberlin surgery is a possible option for recovery of elbow flexion in children with neonatal plexopathy, demonstrating, however, very heterogeneous results, even in the long-term follow-up.

Resumo Objetivo Avaliar a flexão do cotovelo em crianças portadoras de paralisia obstétrica do plexo braquial submetidas à transferência de Oberlin. Métodos Estudo retrospectivo com 11 pacientes acometidos por paralisia decorrente do trabalho de parto e que não apresentaram recuperação espontânea da flexão do cotovelo até os 12 meses de vida, operados entre 2010 e 2018. Resultados As crianças foram operadas entre os 5 e 12 meses de vida, com média de 7,9 meses e o tempo médio de seguimento foi de 133,2 meses, variando de 37 a 238 meses. Seis pacientes (54,5%) apresentaram grau de força muscular ≥ 3, medido pela escala de força do Medical Research Council (MRC), e, pela escala de movimentação ativa (Active Momement Scale [AMS]), 5 pacientes obtiveram pontuação ≥ 5. Foi identificada correlação negativa entre a AMS e a classificação de Narakas (r = -0,509), bem como entre a MRC e a classificação de Narakas (r = -0,495). Já entre a AMS e a MRC, foi observada forte correlação positiva (r = 0,935), demonstrando que quanto maior a pontuação na escala de movimento, maior será a pontuação na escala de força muscular. Conclusão A cirurgia de Oberlin apresenta-se como uma opção possível para a recuperação da flexão do cotovelo em crianças com plexopatia neonatal; no entanto, demonstra resultados bastante heterogêneos, mesmo no seguimento a longo prazo.

First documented clinical account of brachial plexus palsy from the 12th century.

OBJECTIVE: Although literary depiction of brachial plexus injury can be traced to Homer's Iliad, there is a scientific consensus that the first clinical description of brachial plexus palsy was not documented until the British physician Smellie reported it in the 18th century. However, the authors' recent review of the Syriac Book of Medicines (12th century) has uncovered a much earlier clinical documentation. METHODS: For this historical vignette, the authors reviewed the historical and anatomical literature regarding earlier descriptions of brachial plexus anatomy and pathology, including a thorough analysis of the Syriac Book of Medicines (attributed to an unknown Syriac physician in the Middle Ages) and Galen's On Anatomical Procedures and On the Usefulness of the Parts of the Body. RESULTS: Building on the galenic tradition with reference to independent dissections, the Syriac physician discussed nervous system anatomy and the clinical localization of neurological injuries. He described a patient who, after initial pulmonary symptoms, developed upper-extremity weakness more pronounced in the proximal muscles. His anatomical correlation placed the injury "where the nerves issue from the first and second muscles between the ribs" (scalene muscles), are "mixed," and "spread through many parts." The patient's presentation and recovery raise the possibility of Parsonage-Turner syndrome. The anatomical description of the brachial plexus is in line with Galen's earlier account and step-by-step surgical exposure, which the authors reviewed. They also examined Ibn Ilyas' drawing of the brachial plexus, which is believed to be a copy of the earliest artistic representation of the plexus. CONCLUSIONS: Whereas the Middle Ages were seen as a period of scientific stagnation from a Western perspective, Galen's teachings continued to thrive and develop in the East. Syriac physicians were professional translators, clinicians, and anatomists. There is evidence that brachial plexus palsy was documented in the Syriac Book of Medicines 6 centuries before Smellie.

Early and late apoptosis protein expression (Bcl-2, BAX and p53) in traumatic brachial plexus injury.

OBJECTIVES: This research aims to analyze the expression of pro-apoptotic proteins (Bax, p53) and anti-apoptotic protein (Bcl-2) in the nerve roots of the brachial plexus following traumatic brachial plexus injury (TBPI) in the early and late stage. METHODS: A total of 30 biopsy samples were taken from the proximal stump of the postganglionic nerve roots of the TBPI patients' brachial plexus from January 2018 until September 2019. The samples were taken from patients within six months of trauma (early stage, group A) and more than six months following trauma (late stage, group B). Bcl-2, Bax, and p53 expressions in each group were measured and compared. RESULTS: We found significant differences in the Bcl-2 (p=0.04), Bax (p<0.0001), p53 (p<0.0001) expressions between group A and B. The Bcl-2/Bax expression ratio in group A and B was 2.26 and 0.22, respectively. Meanwhile, the Bcl-2/p53 expression ratio in group A and B was 1.64 and 0.23, respectively. CONCLUSION: Apoptosis is inhibited by Bcl-2 activities in the early stage following trauma. In the late stage, a significant decrease of Bcl-2 coupled with a substantial increase of Bax and p53 indicates a continuation of the apoptotic process.

Brachial Plexus Injury Associated with Median Sternotomy during Cardiac Surgery: Three Cases of C8 Radiculopathy Due to the Fracture of the First Rib.

In cardiac surgery, median sternotomy is often necessary during certain surgical processes and it can cause the rare complication of brachial plexus injury. Retraction of the rib cage during median sternotomy may produce a fracture of the first thoracic rib at the costovertebral junction which might penetrate or irritate the lower root of the brachial plexus. Because the C8 ventral root is located immediately superior to the first thoracic rib, the extraforaminal C8 root is thought to be the key location of brachial plexus injury by the first rib fracture. This report describes three cases of brachial plexus injury after median sternotomy in a single center. In our cases, fracture of the first rib and consequent brachial plexus injury is confirmed with imaging and electrophysiologic studies. The fracture of the first rib is not detected with standard plain images and it is confirmed only with CT or MRI studies. Advanced imaging tools are recommended to assess the first rib fracture when brachial plexus injury is suspected after median sternotomy.

The outcome of soft-tissue release and tendon transfer in shoulders with brachial plexus birth palsy.

BACKGROUND: Shoulder involvement in brachial plexus birth palsy is common, and the adduction, internal rotation contracture deformity often requires some form of surgical treatment. There are very few long-term reports on release of contracted muscles and tendon transfers, especially in older children. We are reporting the single-center results of such a surgery with detailed outcome analysis. METHODS: The prospectively collected data from brachial plexus birth palsy cases who had undergone contracture release and tendon transfer were retrospectively studied and examined. The new Mallet and functional scores were compared with the original data forms and then analyzed. The radiographic evidence of glenoid dysplasia and its correlation with age and functional outcome was assessed. RESULTS: A total of 82 cases with surgery at mean age of 9.5 ± 5.09 years and a follow-up of 8 ± 3.8 (3-20) years entered the study. Of these, 56% of cases had 7 to 20 years of age at surgery. Fifty-four (66%) patients had only shoulder surgery, and 28 (34%) required additional reconstructive surgeries for hand and wrist. Moderate to severe glenohumeral dysplasia was present in 38%. The preoperative Mallet score of 10.6 ± 2.97 improved to 19.3 ± 3.39 (P < .001). Eighty-one percent of patients showed improvement in "reaching face" functions, 71% in "above head" functions, and 74% in "midline functions." The cases with lack of improvement in midline function mostly belonged to pan-plexus injuries. Noticeable subjective and objective improvement was also observed in cases with glenohumeral dysplasia in their Mallet and functional scores (P < .001). The improvement in function and subjective satisfaction of 92% was observed irrespective of age at surgery. CONCLUSION: Soft-tissue release and tendon transfer for brachial plexus birth palsy shoulder can improve function and limb appearance even in older children and young adults and even in the presence of glenohumeral dysplasia.

Efeito do treino de alcance combinado com estimulação elétrica em lactentes com paralisia braquial perinatal: estudo experimental de caso único / Efecto del entrenamiento de alcance combinado con electroestimulación en los lactantes con parálisis braquial perinatal: un estudio experimental de caso único / Effect of reaching training combined with electrical stimulation in infants with brachial plexus palsy: a single subject design

RESUMO O objetivo deste estudo foi avaliar o efeito do treino de alcance combinado à estimulação elétrica funcional (FES) na movimentação ativa do membro superior de lactentes com paralisia braquial perinatal (PBP). Trata-se de estudo experimental de caso único do tipo A-B com follow-up. Foram documentados semanalmente dados relativos à função do membro superior (Escala de Movimento Ativo) de dois lactentes, uma menina e um menino de 7 e 10 meses de idade, respectivamente. Após seis avaliações, três vezes por semana, durante duas semanas, na linha de base (A), a intervenção consistiu em aplicar FES Neurodyn® no músculo deltoide em combinação com treino de alcance de objetos, incentivando abdução e flexão anterior de ombro acima de 90°, durante seis semanas, totalizando 15 atendimentos (B). Os lactentes foram reavaliados duas vezes após um período de 15 e 30 dias sem intervenção (follow-up). A pontuação total obtida em cada dia de avaliação foi representada graficamente. Houve boa aceitação da eletroestimulação, sem nenhum efeito colateral. Ambos os lactentes apresentaram melhora da movimentação ativa do membro superior afetado após a intervenção e os ganhos foram mantidos no follow-up, com aumento de 9 e 7 pontos para os lactentes 1 e 2, respectivamente. Seis semanas de intervenção resultaram em mudanças individuais na função do membro superior dos lactentes, principalmente no aumento da amplitude de movimento ativo em flexão e abdução de ombro e flexão de cotovelo. Os resultados deste estudo sugerem o uso de estimulação elétrica como coadjuvante do treino do uso do membro superior afetado de lactentes com PBP.

RESUMEN El objetivo de este estudio fue evaluar el efecto del entrenamiento de alcance combinado con electroestimulación funcional (FES) sobre el movimiento activo de la extremidad superior de los lactantes con parálisis braquial perinatal (PBP). Este es un estudio experimental de caso único de tipo A-B con follow-up. Se registraron semanalmente datos sobre la función del miembro superior (escala de movimiento activo) de dos lactantes, una niña y un niño de 7 y 10 meses de edad, respectivamente. Después de seis evaluaciones, tres veces semanales, durante dos semanas, en la línea base (A), la intervención consistió en aplicar FES Neurodyn® en el músculo deltoides combinado con entrenamiento de alcance de objetos para estimular la abducción y la flexión anterior del hombro por encima de 90°, durante seis semanas, lo que totalizó 15 visitas (B). Se reevaluó a los lactantes dos veces tras el período de 15 y 30 días sin intervención (follow-up). El puntaje total que se obtenía en cada evaluación se representaba gráficamente. Hubo buena aceptación de la electroestimulación, sin efectos secundarios. Ambos lactantes tuvieron mejora en el movimiento activo de la extremidad superior afectada tras la intervención, y los beneficios se mantuvieron en el follow-up, con un aumento de 9 y 7 puntos para los lactantes 1 y 2, respectivamente. Seis semanas de intervención produjeron cambios individuales en la función del miembro superior de los lactantes, principalmente el aumento de la amplitud del movimiento activo en la flexión y abducción del hombro y la flexión del codo. Los resultados sugieren usar la electroestimulación como complemento en el entrenamiento de la extremidad superior afectada de lactantes con PBP.

ABSTRACT This study aimed to evaluate the effect of reaching training combined with functional electrical stimulation (FES) on active upper limb movement in infants with perinatal brachial palsy (PBP). Experimental single-case A-B design with follow-up. Two infants participated in the study, one girl of 7 months and one boy of 10 months of age. Data on infant's upper limb function (Active Movement Scale) were documented weekly. After six baseline assessments (A), 3 times per 2 weeks, intervention consisted of applying FES Neurodyn® to the deltoid muscle combined with objects reach training, encouraging abduction and anterior shoulder flexion above 90º, for six weeks, totaling 15 visits (B). The infants were reevaluated twice after a period of 15 and 30 days without intervention (follow up). The total score obtained on each evaluation day was plotted graphically. Electrostimulation was well accepted, with no side effects. Both infants showed improvement in the active movement of the affected upper limb after the intervention and the gains were maintained at follow-up, an increase of 9 and 7 points for infants 1 and 2, respectively. Six weeks of intervention resulted in individual changes in infant's upper limb function, mainly increased active range of motion in shoulder flexion and abduction and elbow flexion. The results of this study suggest the use of electrical stimulation as an adjunct to training the use of the affected upper limb of infants with PBP.

Treatment of radiation-induced brachial plexopathy with omentoplasty.

Radiation-induced brachial plexus neuropathy (RIBPN) is a rare and delayed non-traumatic injury to the brachial plexus, which occurs following radiation therapy to the chest wall, neck, and/or axilla in previously treated patients with cancer. The incidence of RIBPN is more common in patients treated for carcinoma of the breast and Hodgkin lymphoma. With the improvement in radiation techniques, the incidence of injury to the brachial plexus following radiotherapy has dramatically reduced. The currently reported incidence is 1.2% in women irradiated for breast cancer. The progression of symptoms is gradual in about two-thirds of cases; the patients may initially present with paresthesia followed by pain, and later progress to motor weakness in the affected limb. We present the case of a 68-year-old female patient with breast cancer submitted to surgery, chemotherapy, and radiotherapy in the year 2000. Eighteen years later, she developed symptoms and signs compatible with RIBPN and was successfully submitted to omentoplasty for pain control. Omentoplasty is an alternative treatment for RIBPN refractory to conservative treatment, which seems to be effective in improving neuropathic pain. However, postoperative worsening of the motor strength is a real possibility, and all candidates for this type of surgery must be informed about the risk of this complication.

Chronic Neuropathic Pain of Brachial Plexus Avulsion Mistaken for Amputation Stump Pain for 36 Years: A Case Report.

Following an amputation of the extremities, chronic neuropathic pain and discomfort, such as phantom limb pain (phantom pain), phantom sensation, and stump pain may occur. Clinical patterns of phantom pain, phantom sensation, and pump pain may overlap and these symptoms may also exist in one patient. Serious trauma to the upper limbs can result in brachial plexus avulsion (BPA). If BPA occurs at the same time as severe trauma of the upper extremity and the amputation of the upper limb is performed, chronic neuralgia caused by BPA may be mistaken for chronic amputation pain, such as phantom limb pain or stump pain. No major treatment advances in phantom pain have been made. However, unlike phantom limb pain, chronic neuropathic pain caused by BPA can be effectively treated with dorsal root entry zone lesioning (DREZ)-otomy. We report a patient who suffered for 34 years because the neuralgia caused by BPA was accompanied by an amputation of the arm, and so was thought to be amputation stump pain rather than BPA pain. The patient's chronic BPA pain improved with microsurgical DREZ-otomy.

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.
