Is mirror therapy combined with a routine physiotherapy protocol effective for children with obstetrical upper brachial plexus palsy?

STUDY DESIGN: Randomized controlled study. INTRODUCTION: Mirror therapy is a rehabilitation strategy based on the repeated use of the mirror illusion and also one of the treatment choice of brachial plexus injuries. PURPOSE: We aimed to determine the effects of mirror therapy combined with a routine rehabilitation program on upper limb motor function in children with obstetric brachial plexus injury. METHODS: Twenty children with obstetric brachial palsy were included in this study. They were randomly allocated to either control (n = 10) or mirror therapy (n = 10) group. The following clinical tools were used to assess the upper extremity function: Active Movement Scale (AMS), Modified Mallet Scale (MMS), Hand Grip Strength (HGS) Test, Finger Grip Strength (FGSM) Test, Box and Block Test (BBT), Nine Hole Peg Test (9-HPT), and goniometric measurement. Both groups received the same routine physiotherapy program for 8 weeks. The study group underwent mirror therapy in addition to the rehabilitation program. RESULTS: The mean age of the study population was 11.35 ± 4.12 years. There was no change in the goniometric values, AMS and MMS scores after the treatment in both groups (p > 0.05), except for the improvement of the wrist extension in the study group (p < 0.05). There was an increase in both HGS and FGS scores in the study group. Only FGS scores improved in the control group after the intervention (p < 0.05). 9-HPT and BBT scores improved in both groups (p < 0.05). All other parameters tested were comparable between the two groups after the treatment. CONCLUSIONS: The results of this study did not show any additional benefits of mirror therapy combined with a rehabilitation protocol compared to routine physiotherapy treatment, but was not adequately powered to do so.

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.

Integrated Electromyography: Discriminant Analysis and Prediction of Recovery 3 to 6 Years After Brachial Plexus Birth Injury.

PURPOSE: To assess the recovery likelihood, 3 to 6 years after brachial plexus birth injury (BPBI), and predict the functional recovery from integrated electromyography (IEMG). METHODS: Thirty children with BPBI limited to C5-C6 lesion participated. Maximal electromyography activity of deltoid and biceps brachii was measured at entry. Shoulder and elbow functions were assessed at the baseline and at 4 intervals across 2 years. RESULTS: Shoulder and elbow function significantly changed across the follow-up period. Shoulder and elbow functions were significantly dependent on deltoid and biceps brachii muscles' IEMG level, respectively, with the groups showing higher IEMG achieving better recovery. The deltoid and biceps IEMG explained a portion of the improvement in shoulder and elbow function over 2 years. CONCLUSION: Recovery of the shoulder and elbow function continues 3 to 6 years after BPBI. IEMG may partially explain variation in the prognosis for children with BPBI.

Scapular Stabilization Limits Glenohumeral Stretching in Children With Brachial Plexus Injuries.

PURPOSE: To quantify the effects of scapular stabilization on scapulothoracic and glenohumeral (GH) stretching. METHODS: Motion capture data during external rotation and abduction with and without scapular stabilization were collected and analyzed for 26 children with brachial plexus birth palsy. These positions were performed by an experienced occupational therapist and by the child's caretaker. Scapulothoracic and GH joint angular displacements were compared between stretches with no stabilization, stabilization performed by the therapist, and stabilization performed by the caretaker. The relationship between the age and ability of the therapist and caretaker to perform the stretches with scapular stabilization was also assessed. RESULTS: During external rotation there were no significant differences in either the scapulothoracic or GH joint during stabilization by either the therapist or the caretaker. During abduction, both scapulothoracic and GH joint angular displacements were statistically different. Scapulothoracic upward rotation angular displacement significantly decreased with scapular stabilization by the therapist and caretaker. Glenohumeral elevation angular displacement significantly decreased with scapular stabilization performed by the therapist and caretaker. There were only weak correlations between age and the differences in scapulothoracic and GH joint angular displacement performed by both the therapist and the caretaker. CONCLUSIONS: The findings of this study indicate that scapular stabilization may be detrimental to passive stretching of the GH joint in children, as demonstrated by a reduced stretch. Based on the findings of this study, we have changed our practice to recommend passive stretches without scapular stabilization for children aged 5 years and older with brachial plexus birth palsy. In infants and children aged less than 5 years, we now recommend stretching with and without scapular stabilization until the effect of scapular stabilization is objectively assessed in these age groups. LEVEL OF EVIDENCE/TYPE OF STUDY: Therapeutic IV.

Efficacy of 3 therapeutic taping configurations for children with brachial plexus birth palsy.

STUDY DESIGN: Cross-sectional clinical measurement study. INTRODUCTION: Scapular winging is a frequent complaint among children with brachial plexus birth palsy (BPBP). Therapeutic taping for scapular stabilization has been reported to decrease scapular winging. PURPOSE OF THE STUDY: This study aimed to determine which therapeutic taping construct was most effective for children with BPBP. METHODS: Twenty-eight children with BPBP participated in motion capture assessment with 4 taping conditions: (1) no tape, (2) facilitation of rhomboid major and rhomboid minor, (3) facilitation of middle and lower trapezius, and (4) facilitation of rhomboid major, rhomboid minor, and middle and lower trapezius (combination of both 2 and 3, referred to as combined taping). The participants held their arms in 4 positions: (1) neutral with arms by their sides, (2) hand to mouth, (3) hand to belly, and (4) maximum crossbody adduction (CBA). The scapulothoracic, glenohumeral and humerothoracic (HT) joint angles and joint angular displacements were compared using multivariate analyses of variance with Bonferroni corrections. RESULTS: Scapular winging was significantly decreased in both the trapezius and combined taping conditions in all positions compared with no tape. Rhomboids taping had no effect. Combined taping reduced HT CBA in the CBA position. CONCLUSIONS: Rhomboid taping cannot be recommended for treatment of children with BPBP. Both trapezius and combined taping approaches reduced scapular winging, but HT CBA was limited with combined taping. Therefore, therapeutic taping of middle and lower trapezius was the most effective configuration for scapular stabilization in children with BPBP. Resting posture improved, but performance of the positions was not significantly improved. LEVEL OF EVIDENCE: Level II.

Effect of virtual reality versus conventional physiotherapy on upper extremity function in children with obstetric brachial plexus injury.

OBJECTIVES: The objective was to evaluate the effects of virtual reality versus conventional physiotherapy on upper extremity function in children with obstetric brachial plexus injury. METHODS: Forty children with Erb's palsy were selected for this randomized controlled study. They were assigned randomly to either group A (conventional physiotherapy program) or group B (virtual reality program using Armeo® spring for 45 min three times/week for 12 successive weeks). Mallet system scores for shoulder function and shoulder abduction, and external rotation range of motion (ROM) were obtained; shoulder abductor, and external rotators isometric strength were evaluated pre-and post-treatment using Mallet scoring system, standard universal goniometer, and handheld dynamometer. RESULTS: The results of this study indicate that the children in both groups showed improvement in shoulder functions post-treatment with greater improvements in group B. The abduction muscle strength after treatment was 8.53 and 11.3 Nm for group A and group B, respectively. The external rotation muscle strength after treatment was 5.88 and 7.45 Nm for group A and group B, respectively. CONCLUSIONS: The virtual reality program is a significantly more effective than conventional physiotherapy program in improving the upper extremity functions in children with obstetric brachial plexus injury.

Using Contingent Reinforcement to Augment Muscle Activation After Perinatal Brachial Plexus Injury: A Pilot Study.

AIM: Examine the feasibility of increasing muscle activation with electromyographically (EMG)-triggered musical-video as reinforcement for children with perinatal brachial plexus injury (PBPI). METHODS: Six children with PBPI (9.3 ± 6.3 months; 5 female, 1 male) and 13 typically developing (TD) controls (7.8 ± 3.5 months; 4 female, 9 males) participated. The left arm was affected in 5/6 children with PBPI. We recorded the integral (Vs) of biceps activation with surface EMG during two conditions per arm in one session: (1) 100 second (s) baseline without reinforcement and (2) 300 s reinforcement (musical-video triggered to play with biceps activation above threshold [V]). We examined the relation between the mean integral with reinforcement and hand preference. RESULTS: Mean biceps activation significantly increased from baseline in the affected arm of the group with PBPI by the 2nd (p < .008) and 3rd (p < .0004) 100 s intervals of reinforcement. Six of 6 children with PBPI and 12/13 TD controls increased activation in at least one arm. A lower integral was linked with hand preference for the unaffected right side in the PBPI group. CONCLUSION: This study supports contingent reinforcement as a feasible method to increase muscle activation. Future work will examine training dose and intensity to increase arm function.

Bionic reconstruction to restore hand function after brachial plexus injury: a case series of three patients.

BACKGROUND: Brachial plexus injuries can permanently impair hand function, yet present surgical reconstruction provides only poor results. Here, we present for the first time bionic reconstruction; a combined technique of selective nerve and muscle transfers, elective amputation, and prosthetic rehabilitation to regain hand function. METHODS: Between April 2011, and May 2014, three patients with global brachial plexus injury including lower root avulsions underwent bionic reconstruction. Treatment occurred in two stages; first, to identify and create useful electromyographic signals for prosthetic control, and second, to amputate the hand and replace it with a mechatronic prosthesis. Before amputation, the patients had a specifically tailored rehabilitation programme to enhance electromyographic signals and cognitive control of the prosthesis. Final prosthetic fitting was applied as early as 6 weeks after amputation. FINDINGS: Bionic reconstruction successfully enabled prosthetic hand use in all three patients. After 3 months, mean Action Research Arm Test score increased from 5·3 (SD 4·73) to 30·7 (14·0). Mean Southampton Hand Assessment Procedure score improved from 9·3 (SD 1·5) to 65·3 (SD 19·4). Mean Disabilities of Arm, Shoulder and Hand score improved from 46·5 (SD 18·7) to 11·7 (SD 8·42). INTERPRETATION: For patients with global brachial plexus injury with lower root avulsions, who have no alternative treatment, bionic reconstruction offers a means to restore hand function.

Tactile feedback for relief of deafferentation pain using virtual reality system: a pilot study.

BACKGROUND: Previous studies have tried to relieve deafferentation pain (DP) by using virtual reality rehabilitation systems. However, the effectiveness of multimodal sensory feedback was not validated. The objective of this study is to relieve DP by neurorehabilitation using a virtual reality system with multimodal sensory feedback and to validate the efficacy of tactile feedback on immediate pain reduction. METHODS: We have developed a virtual reality rehabilitation system with multimodal sensory feedback and applied it to seven patients with DP caused by brachial plexus avulsion or arm amputation. The patients executed a reaching task using the virtual phantom limb manipulated by their real intact limb. The reaching task was conducted under two conditions: one with tactile feedback on the intact hand and one without. The pain intensity was evaluated through a questionnaire. RESULTS: We found that the task with the tactile feedback reduced DP more (41.8 ± 19.8 %) than the task without the tactile feedback (28.2 ± 29.5 %), which was supported by a Wilcoxon signed-rank test result (p < 0.05). CONCLUSIONS: Overall, our findings indicate that the tactile feedback improves the immediate pain intensity through rehabilitation using our virtual reality system.

Home-based movement therapy in neonatal brachial plexus palsy: A case study.

STUDY DESIGN: Case report. INTRODUCTION: The value of movement-based therapy in peripheral nerve injury conditions such as neonatal brachial plexus palsy (NBPP) is unclear. PURPOSE OF THE STUDY: To determine the effectiveness of a home-based movement therapy program in a 17 year old female patient with a right NBPP pan-plexopathy. METHODS: Home training consisted of arm reaching and object manipulation tasks using devices which recorded performance. Training occurred for 1 h/day, 5 days/week for 6 weeks with periodic webcam supervision. Pre- and post clinical, functional and kinematic assessments were performed in a laboratory setting. RESULTS: Following training, shoulder flexion and elbow extension active range of motion increased by 13° and 9°, respectively, and functional ability also improved. Reach movement duration decreased significantly with a concomitant improvement in movement coordination. CONCLUSIONS: These results demonstrate that movement therapy has the potential to improve motor function in NBPP years after the initial insult. LEVEL OF EVIDENCE: 4.

Therapeutic application of electrical stimulation and constraint induced movement therapy in perinatal brachial plexus injury: A case report.

Infants and children with perinatal brachial plexus injury (PBPI) have motion limitations in the shoulder, elbow, forearm and hand that are dependent on the level of injury and degree of recovery. The injury and subsequent recovery period occur during critical periods of central and spinal neural development placing infants and children at-risk for developmental disregard and disuse of the affected arm and hand. A case report outlines the therapy and surgical interventions provided in the first 2 years of life for a child with global PBPI and a positive Horner's sign. Electrical stimulation and constraint induced movement therapy provided sequentially were effective therapy interventions. Neurosurgery to repair the brachial plexus was performed at an optimal time period.(2) The Assisting Hand Assessment,(12) Modified Mallet(13) and Active Movement Scale(14) are effective outcome measures in PBPI and served as valuable guides for therapy intervention.

Clinical assessment of the infant and child following perinatal brachial plexus injury.

STUDY DESIGN: Literature review. INTRODUCTION: After perinatal brachial plexus injury (PBPI), clinicians play an important role in injury classification as well as the assessment of recovery and secondary conditions. Early assessment guides the initial plan of care and influences follow-up and long-term outcome. PURPOSE: To review methods used to assess, classify and monitor the extent and influence of PBPI with an emphasis on guidelines for clinicians. METHODS: We use The International Classification of Functioning, Disability, and Health (ICF) model to provide a guide to assessment after PBPI for rehabilitation clinicians. DISCUSSION: With information gained from targeted assessments, clinicians can design interventions to increase the opportunities infants and children have for optimal recovery and to attain skills that allow participation in areas of interest.

Delayed selective neurotization for restoration of elbow and hand functions in late presenting obstetrical brachial plexus palsy.

The published experience of obstetrical brachial plexus palsy (OBPP) cases with poor recovery and late neurosurgical intervention are sparse. This study included 19 cases who presented after the age of 1 year with poor recovery of elbow and/or hand function and electrophysiological evidence of reinnervation. Age at surgery averaged 41 months, and the follow-up averaged 50 months. Distal neurotization was performed for restoration of elbow flexion in 11 cases, elbow extension in 3 cases, and finger flexion and/or sensibility in 5 cases. Active elbow flexion increased from an average of 2.7 to 91.8 degrees with an average gain of 89 degrees. Active elbow extension increased from an average of 10 to 56.7 degrees with an average gain of 46.7 degrees. Although, three out of five cases (60%) showed satisfactory recovery of finger flexion, all cases scored<2 using Raimondi score. Four cases gained protective sensation and one case gained discriminative sensation. The results of neurotization in late OBPP are variable. The best and most consistent results are obtained by necrotizing the biceps by the intercostal nerves or, in selected cases, by the flexor carpi ulnaris fascicle of the ulnar nerve. Delayed neurotization is the only way to recover sensory function in the hand.

Sup-ER orthosis: an innovative treatment for infants with birth related brachial plexus injury.

Impairments in active and passive range of upper extremity supination and shoulder external rotation are common sequelae for children with delayed recovery from birth related brachial plexus injury. Orthotic intervention may complement traditional treatment strategies commonly employed in the newborn period. These authors describe their custom fabricated orthosis designed to balance shoulder growth and muscular function, and improve prognosis of long term functional outcomes for children with birth related brachial plexus injury. - Victoria Priganc, PhD, OTR, CHT, CLT, Practice Forum Editor.

Rehabilitation of brachial plexus injury in contact sport: Where are the data that underpin clinical management? A scoping review.

BACKGROUND: Although a common injury there is a lack of published primary data to inform clinical management of sports related brachial plexus injuries. METHODS: A systematic search was completed in Medline, CINAHL, PubMed, SPORTDiscus and Web of Science databases and Google Scholar from inception to August 2023 according to the PRISMA-ScR guidelines. Methodological quality assessment of included articles was with the Joanna Briggs Institute tool. Studies providing primary data as to the rehabilitative management of diagnosed or suspected brachial plexus injuries sustained when playing contact sports were included. RESULTS: Sixty-five studies were identified and screened, of which, 8 case reports were included, incorporating 10 participants with a mean age of 19.8 (±4.09) years. There was wide heterogeneity in injury severity, injury reporting, physical examination and imaging approaches documented. 9 of 10 participants returned to competitive sports, though follow-up periods also varied widely. Whilst return to play criteria varied between studies, the most consistent indicator was pain-free shoulder range of motion and strength. CONCLUSIONS: There is a distinct lack of data available to inform evidence-based rehabilitation management of sports related brachial plexus injury. Only 8 individual case reports contain published data reporting on 10 athletes. Further reporting is critical to inform clinical management.

Isolated lower brachial plexus (Klumpke) palsy with compound arm presentation: case report.

Klumpke palsy has yet to be clearly documented in the newborn, because previous reports lack any description of the obstetrical history, clinical progression, or outcome. Based on a high incidence of breach presentation in the few clinical series that report Klumpke palsy, hyperabduction with arm overhead during delivery has been the presumed mechanism. We report a child with isolated lower brachial plexus palsy and Horner syndrome who presented at birth with a vertex compound arm presentation. Recognition of this condition and details of the clinical progression and outcome are important, because guidelines for management are currently not available.

Bilateral wrist drop complicating axillary crutches mobilization in a young adult.

OBJECTIVE: Axillary crutches are simple rehabilitative devices that are globally used temporarily or permanently to assist in ambulation of patients and rarely present with complication. This report is about bilateral wrist drop incidentally noticed in a young adult patient mobilized on axillary crutches after internal fixation of a simple right tibia fracture. METHODS: The fracture was fixed by intramedullary nailing and the patient was mobilized on axillary crutches. At six weeks, patient fearfully refused to be commenced on partial weight bearing and at 12 weeks after surgery he was noticed to be totally weightbearing on the bars of the appropriately long axillary crutches and had developed bilateral wrist drop. There was radiological evidence of healing at the fracture sites. Treatment included mobilization on one elbow crutch on the left, physical therapy and nerve stimulation. RESULTS: At six weeks of physiotherapy, the power of the dorsiflexors of the wrists had recovered completely. CONCLUSION: Bilateral posterior cord palsy of brachial plexus could occur even in young healthy patients but total recovery could occur if the diagnosis and treatment are prompt. Patients should be told in unequivocal terms not to weight bear directly on axillary bars.

[Management of upper obstetrical brachial plexus palsy. Long-term results of non-operative treatment in 22 children]. / Traitement conservateur des paralysies obstétricales hautes du plexus brachial. Résultats à long terme chez 22 enfants.

INTRODUCTION: Treatment of obstetrical brachial plexus palsy (OBPP) is always debated, especially for upper plexus palsy. Some authors perform early surgical treatment in case of absence of biceps contraction at the age of 3 months. Others prefer to wait until the age of 6 months before considering a surgical procedure when no suspicion of root avulsion is found. We think that a conservative approach with intensive rehabilitation program can obtain good functional outcome for patients who will recover biceps function spontaneously between 3 and 6 months, and that it is not necessary to perform surgery at 3 months. To argue our choice, we have compared the long-term outcome of two groups of children with upper OBPP conservatively treated regarding the age of biceps recovery (before or after 3 months). PATIENTS AND METHODS: Twenty-two patients with non operated upper roots birth palsy, followed in Timone's Hospital of Marseille by a multidisciplinary team, have recovered a biceps contraction between 1 and 8 months and were retrospectively included in this study. All children underwent an intensive rehabilitation program since birth, performed by a specialized physiotherapist. Patients were reviewed, and their shoulder function was assessed using Mallet score. The score was analysed regarding the age of biceps recovery. RESULTS: The mean follow up was 8.2 years. Nine children recovered a biceps contraction at 3 months of age or before; the mean global Mallet score was 4.11. Thirteen children recovered a biceps contraction after 3 months of age (between 3 and 8 months); the mean global Mallet score was 3.92. The difference was not statistically significant. CONCLUSION: This study shows that global shoulder function is comparable for two groups. The children who did not recover a biceps contraction at 3 months of age had a global shoulder function as good as the one who recovered biceps function earlier. We think our intensive rehabilitation program allowed us to avoid a useless early surgery. Surgical plexus treatment was indicated for children who did not have biceps contraction after 6 months of age.
