Abstract
For major upper limb defects, a wide range of established pedicled and free flap options can be used. These include the latissimus dorsi/thoracodorsal artery perforator, lateral arm, posterior interosseous artery, rectus abdominis, gracilis, and anterolateral thigh flaps. Technical proficiency is essential, and favorable success rates in terms of functional and esthetic outcomes can be achieved. Herein, alternative flap options (both pedicled and free) are introduced and discussed through a few illustrative case examples.

Abstract
Dorsal seroma is a common complication of autologous latissimus dorsi flap (ALDF) in breast reconstruction, and has limited the use of this technique, despite its aesthetic success. It is important to find a right technique to limit the incidence of seroma formation after ALDF. The aim of this study was to evaluate the effectiveness and tolerance of a dorsal quilting technique called "running quilting" using barbed resorbable suture in seroma prevention. Three hundred patients who underwent ALDF breast reconstruction in the period between 2004 and 2014 were included in this study. The population was divided in 3 groups; without quilting, with simple quilting suture, and with running quilting using barbed suture. The incidence of small seromas (requiring 1 or 2 aspirations during routine postoperative visits without adding additional appointments to the follow-up routine) was not significantly decreased: it was 54% in the non-quilted group, 47% in group 2 Quilting, and 34% in group 3 running quilting. However, quilting reduced the duration of drainage, and the rate of late seromas (from 8% to 0%), and chronic sero-hematomas completely disappeared in our experience. Running quilting using barbed suture is highly effective in preventing late and refractory donor-site seromas. Its effectiveness is expected to increase the use of ALDF in breast reconstruction, which we consider currently as one of the best autologous reconstruction techniques.

Abstract
Increasing chair recline during seated computer work may reduce the load placed on the upper trapezius (UT), a common location of pain for those with idiopathic chronic neck pain. This study determined the effect of increasing chair recline on UT stiffness and muscle activity during computer work in people with and without idiopathic chronic neck pain. Surface electromyography and ultrasound shear wave elastography were collected from three subdivisions of the UT in 15 individuals with idiopathic chronic neck pain and 15 sex-matched healthy controls. Participants sat in a standardized computer-work setup while chair recline (0°, 25°, 45°) and head and neck position (self-selected, neutral, flexed) were systematically adjusted and maintained for 2.5-min intervals. Repeated-measures ANOVAs were completed for each sex, muscle, and data type, with group (chronic neck pain, control), chair recline (0°,25°,45°), head and neck position (self-selected, flexed, neutral), and side of collected data (dominant, non-dominant) as fixed factors. Men with idiopathic chronic neck pain demonstrated greater UT stiffness in the cranial subdivision when compared to healthy men. Additionally, the 25° and 45° recline levels increased the stiffness of men's dominant UT compared to men's non-dominant UT. Women's UT was more affected by head and neck position, and a neutral head and neck position resulted in lower UT activation, but higher UT stiffness for the cranial subdivision and midway between C-7 and the acromion process. Overall, our findings suggest that the commonly suggested neutral position may not be a beneficial prompt when positioning someone during seated computer work.

Abstract
BACKGROUND The latissimus dorsi free flap is a widely used reconstructive technique for complex lower leg defects in the pediatric population due to its reliability and anatomical features. However, the impact of this technique on the postoperative quality of life in children and adolescents, who require appropriate lower extremity function during their developmental period, remains to be analyzed. METHODS Patients who underwent microsurgical lower leg reconstruction using the latissimus dorsi flap were analyzed retrospectively. The quality of life of these patients was assessed prospectively using the Lower Extremity Functional Scale (LEFS) at a minimum of 18 months after surgical reconstruction. RESULTS Sixteen pediatric patients who had severe lower extremity injuries and underwent latissimus dorsi free flap reconstruction met the inclusion criteria. The mean follow-up period was 33.9 months (22-64 months). Two patients experienced postoperative complications: one had partial flap necrosis and surgical site infection, while the other developed a surgical site infection. The LEFS scores ranged from 26 to 80, with a mean score of 64.6. Remarkably, 14 of 16 patients achieved LEFS scores consistent with at least the 10th percentile when compared with normative data. Patients with severe associated fractures presented with the lowest scores. CONCLUSIONS Based on our findings, the latissimus dorsi flap is reaffirmed to be an excellent choice for lower leg reconstruction in the pediatric population. It effectively restores the quality of life in patients who have experienced moderate to severe lower extremity injuries.

Abstract
OBJECTIVE This study aimed to investigate the difference between the integrated neuromuscular inhibition technique (INIT) and spray and stretch technique in patients with neck pain and upper trapezius active trigger points. Methods: A convenience sample of 60 patients with neck pain and active trigger points were recruited from physiotherapy students and allocated randomly to three groups INIT plus stretching exercise spray and stretch technique plus stretching exercise, and stretching exercise only. Treatment was three times per week for four weeks. Pain intensity by visual analogue scale (VAS), pain pressure threshold (PPT), neck disability by Arabic neck disability index (ANDI), and muscle amplitude in the form of root mean square (RMS) by electromyography (EMG) were measured at baseline and after four weeks. Results: Between groups analysis; the results revealed statistical significant difference between three groups after four weeks of intervention as p =0.0001. Within the group analysis, post hoc tests reported improvement at all variables in both INIT and spray and stretch technique groups with mean differences 64.5 and 65.1 in VAS, 20 and 18.15 in ANDI, -1.45 and -0.81 in PPT, and 2.47 and 1.88 in muscle amplitude, respectively. But there was no statistically significant difference in stretching only group in all variables except VAS. CONCLUSION Both INIT and spray and stretch techniques had a clinical and statistical effects on pain, function, PPT, and RMS. According to results, there were statistical significant differences between INIT and spray and stretch groups at post-treatment in all variables except VAS with more favor to INIT group, but there were no clinical differences between INIT and spray and stretch groups.

Abstract
INTRODUCTION While the well-established correlation between increased muscle volume and enhanced muscle strength is widely recognized, there have been no studies assessing volumetric muscle changes in transfer surgery in the shoulder. This study aimed to evaluate changes in transferred muscle volume and their clinical implications in anterior latissimus dorsi and teres major (aLDTM) tendon transfer in patients with anterior superior irreparable rotator cuff tears (ASIRCTs). MATERIALS AND METHODS The study retrospectively examined 40 patients who underwent aLDTM tendon transfers for ASIRCTs between August 2018 and January 2022. Using ImageJ software, the LDTM muscle was segmented in T2-weighted oblique axial images, and total muscle volume (tLDTMV) of both immediate and postoperative 1-year were calculated. Pearson correlation analysis was used to determine the correlation between ΔtLDTMV and ΔASES scores, Δactive-ROM, and Δstrength. RESULTS The current study revealed an 11.4% increase in tLDTMV at 1-year postoperative. Patients were grouped based on postoperative ASES score: Group 1 (Optimal, n = 17) and Group 2 (Suboptimal, n = 23). Although tLDTMVimmediate postoperative values were similar between groups (P = 0.954), tLDTMV1-year postoperative value was significantly higher in Group 1 compared to Group 2 (P = 0.021). In correlation analysis, ΔtLDTMV showed significant correlations with ΔASES score (r = 0.525, P < 0.001), ΔaROM of forward elevation (FE) (r = 0.476, P = 0.002), ΔaROM of internal rotation (IR) at back (r = 0.398, P = 0.011), Δstrength of FE (r = 0.328, P = 0.039), Δ strength of IR at 90° abduction (r = 0.331, P = 0.037), and IR at side (r = 0.346, P = 0.029). CONCLUSIONS Significant increase in tLDTMV was observed at 1-year postoperative for ASIRCT patients. Notably, greater ΔtLDTMV exhibited a correlation with better ASES scores, increased aROM and strength in both FE and IR. Nevertheless, further research is required by employing more robust standardized measurement tools and a larger sample size.

Abstract
INTRODUCTION Treating global irreparable rotator cuff tears (GIRCTs) that involve both antero-and postero-superior cuff tendon tears could be a challenging problem. There has been limited joint-preserving treatment options in high-demand patients with minimal glenohumeral arthritis. The study aims to assess the clinical outcome of combined anterior latissimus dorsi and teres major tendon (aLDTM) transfer for patients with both GIRCTs and minimal glenohumeral arthritis. MATERIALS AND METHODS This retrospective study included patients who underwent combined aLDTM transfer for GIRCTs between 2018 May and 2020 October. Clinical outcomes include pain VAS, Constant, American Shoulder and Elbow Society (ASES), University of California Los Angeles (UCLA), activities of daily living requiring active internal rotation (ADLIR) score, active range of motion (aROM), strength, rates of pseudoparalysis or pseudoparesis reversal and return to work. Radiographic assessment included the acromiohumeral distance (AHD), Hamada grade, and transferred tendon integrity at final follow-up. RESULTS 23 patients (mean age: 64.7 ± 5.9 years [55-74]) were included and the mean follow-up period was 28.2 ± 4.3 [24‒36] months. Postoperatively, VAS, Constant, ASES, UCLA, and ADLIR scores significantly improved at final follow-up (P < .001). Postoperative aROM was significantly improved in forward elevation (FE) to 129° ± 29°, abduction (ABD) to 105° ± t3°, and internal rotation (IR) at back to 5.9 ± 2.5. Strength of both FE and IR were also significantly improved (P < .001). Patients with preoperative pseudoparalysis (2 of 4 patients) and pseudoparesis (6 of 6 patients) experienced a reversal. No significant change in AHD and hamada grade was confirmed at final follow-up. 3 patients experienced partial tear of the transferred tendon. CONCLUSIONS In this study, we found significant improvement in clinical outcomes with no significant progression of arthritis by final follow-up. The aLDTM transfer could be an alternative choice of joint-preserving treatment option for young and active patients with GIRCTs and minimal glenohumeral arthritis. However, large and long-term studies should be conducted to establish its adequacy. STUDY DESIGN Case series. LEVEL OF EVIDENCE IV.

Abstract
The trapezius muscle (TRAP) belongs to the scapulothoracic group of muscles, which play a crucial role in the integrity and strength of the upper limb, trunk, head, and neck movements and, thus, in maintaining balance. Combined retrograde tracing (using fluorescent tracer Fast Blue, FB) and double-labelling immunohistochemistry were applied to investigate the chemical coding of motoneurons projecting to the porcine TRAP. FB-positive (FB+) motoneurons supplying the cervical (c-TRAP) and thoracic part (th-TRAP) of the right (injected with the tracer) TRAP were located within the IX-th Rexed lamina in the ipsilateral ventral horn of the grey matter of the spinal medulla. Immunohistochemistry revealed that nearly all the neurons were cholinergic in nature [choline acetyltransferase (CHAT)- or vesicular acetylcholine transporter (VACHT)-positive]. Many retrogradelly labelled neurons displayed also immunoreactivity to calcitonin gene-related peptide (CGRP; approximately 68% of FB+ neurons). The smaller number of nerve cells (5%, 3%, 2% or 1%, respectively) stained for nitric oxide synthase (n-NOS), vasoactive intestinal polypeptide (VIP), neuropeptide Y (NPY) and substance P (SP). The retrogradely labelled neurons were closely apposed by nerve fibres expressing immunoreactivity to CHAT, VACHT, CGRP, SP, DβH, VIP, n-NOS, NPY, GAL, Leu-Enk and Met-Enk. Taking into account the clinical relevance of TRAP, the present results may be useful in designing further research aimed at the management of various dysfunctions of the muscle.

Abstract
SUMMARY The conjoined latissimus dorsi-groin flap is a versatile flap that not only can serve as an osteocutaneous flap to provide large soft tissue and bone for reconstruction of extensive defects but also can offer functioning muscle transfer and lymph node transfer for prevention of lymphedema after wide excision of tumors or major trauma. Over the past 24 years, the authors have classified the conjoined latissimus dorsi-groin flap into four categories. They propose precautions for application of the conjoined flaps.

Abstract
The deep neck flexors are important for maintaining neck posture by stabilizing and supporting it through low-intensity contraction, ensuring static endurance. The subjects performed computer tasks after having their deep neck flexor endurance measured using a pressure biofeedback unit. The craniovertebral angle (CVA) and the muscle activities were measured while participants were completing computer tasks for 10 min. The deep neck flexor endurance was significantly negatively correlated with CVA changes at 0-2 min. The deep neck flexor endurance was significantly negatively correlated with sternocleidomastoid muscle and upper trapezius activity at 0-2 min. The deep neck flexor endurance negatively predicted CVA changes at 0-2 min and explained 28.8% of the variance in the CVA changes. The lower the deep neck flexor endurance, the earlier the simultaneous changes occurred in the CVA and the neck and shoulder muscle activities during computer tasks.

Abstract
The contour of the neck and shoulder is defined by the trapezius muscle (TM). Beyond facial procedures, botulinum toxin A (BoNT-A) injections has been increasingly adopted to create a smooth shoulder line. Several studies described the intramuscular nerve branching and the pattern of perforating branch of the accessory nerve in the trapezius muscle, providing essential information for botulinum neurotoxin injection. To this date, research groups seldom perform clinical investigations, especially randomized controlled trials, that demonstrates whether BoNT-A injections using the nerve distribution method for aesthetic purposes is more effective. Patients met the criteria for inclusion were randomized to either the Nerve Distribution group (ND group) or control group. Control group patients received injection using the conventional method while ND group patients received the nerve distribution method. Photographic and ultrasonographic evaluations were carried out at baseline, one month, three months, and six months after the procedure. Patients were also required to complete a questionnaire to evaluate their feedbacks to the injection. After screening, 30 healthy young Chinese women were included. At one-month follow-up, no statistically significant difference was observed between the two methods. At the three-month follow-up, the reduction of the TM thickness for the ND group (0.21 ± 0.09 cm) was more than that for the control group (0.27 ± 0.08 cm), with p = 0.047*. Similar differences were observed for the reduction of the shoulder area proportion (p = 0.031*) and the shoulder angle (p = 0.035*). At the six-month follow-up, the reduction in TM thickness in the ND group (0.2 ± 0.09 cm) was more than that of the control group (0.28 ± 0.06 cm), with p = 0.041*. The global aesthetic improvement scale feedbacks of the two methods showed no significant difference (3.4 ± 0.71 vs 3.8 ± 0.91, p = 0.207). The patients did not experience severe side effects. Compared to the conventional injection method, the nerve distribution method is more effective in reducing the trapezius muscle thickness, shoulder area proportion, and shoulder angle at three months, and shows longer lasting effects. The results of this study introduce unique insights into the design and tailoring of treatment protocols for shoulder-line contouring using BoNT-A.Level of Evidence I This journal requires that authors assign a level of evidence to each article.

Abstract
BACKGROUND Sleep disturbances frequently occur in patients with chronic neck pain. In these patients, upper trapezius muscle dysfunction is observed during sleep. This study aimed to evaluate the trapezius muscle activity during sleep among patients with chronic neck pain and sleep disturbances for comparison with healthy subjects. STUDY DESIGN: Cross-sectional study. METHODS Patients with chronic neck pain and healthy subjects participated in the study. Two overnight polysomnography recordings were conducted for each subject. Surface electromyography was utilized to record the nocturnal activity of the right and left upper trapezius muscles throughout the night. The nocturnal upper trapezius activity recording was divided into the following parts: wakefulness, rapid eye movement sleep (REM), and non-rapid eye movement sleep (NREM). The nocturnal activity during NREM sleep was further divided into three parts (stage I NREM sleep, stage II NREM, and stage III NREM. Normalization of EMG signals was performed. The normalized value of nocturnal activity was derived for analysis. RESULTS Among 15 patients with chronic neck pain and 15 healthy subjects, statistically significant differences were observed in the nocturnal activity of the upper trapezius. Compared to healthy subjects, the nocturnal activity of the upper trapezius was significantly higher during wakefulness, REM sleep, and NREM II and III sleep in patients with chronic neck pain and sleep disturbances. CONCLUSION There was higher nocturnal upper trapezius activity in patients with chronic neck pain compared to healthy controls. The findings suggest a possible pathophysiological mechanism that may relate to chronic neck pain. TRIAL REGISTRATION CTRI/2019/09/021028.

Abstract
This study investigated the relationship between the stiffness of the upper trapezius muscle and the range of rotational movement of the cervical spine. A total of 60 right-handed asymptomatic students participated in the study. Participants (N = 22) characterised by asymmetry in rotational movements were selected for the experimental group. A difference of ≥10° between right and left rotation of the cervical spine was considered asymmetrical. The control group (N = 38) included participants whose rotation difference was < 10°. Belonging to the experimental or control group did not significantly differentiate trapezius muscle stiffness. The rotation side differentiated the stiffness of the right and left trapezius muscles only in the group of people with rotational movement asymmetry. There were high correlation coefficients between right cervical rotation and the stiffness of the muscle on the right side, and between rotation to the left and the stiffness of the muscle on the left side. There is a relationship between the stiffness of the right and left upper trapezius muscles and the range of right and left rotational motion of the cervical spine. Stiffness of the upper trapezius correlates more strongly with rotation to the side on which the muscle lies than to the opposite side. Increased stiffness of the upper trapezius muscle on the side of limited cervical spine rotation is likely to be determined by the muscle fibre stretching mechanism.

Abstract
BACKGROUND AND OBJECTIVES Neoadjuvant chemotherapy (NCH) has demonstrated efficacy in downsizing tumors and facilitating less extensive surgery. However, immediate breast reconstruction (IBR) after NCH has raised concerns regarding higher complication rates. This study evaluates the impact of NCH on outcomes following IBR with a latissimus dorsi flap and implant (LDI) after mastectomy. METHODS Cases from a prospective maintained database were reviewed, and patients classified according to whether or not they received NCH. Risk factors and major and minor complications in both groups were then analyzed. RESULTS Among the 196 patients who underwent 198 IBR procedures, 38.4% received NCH and 66.1% did not. The overall complication rate was 46.7% in the non-NCH group and 53.3% in the NCH group (p = 0.650). The presence of comorbidities increased the likelihood of any complication (odds ratio [OR]: 3.46; 95% confidence interval [CI]: 1.38-8.66; p = 0.008) as well as major complications (OR: 3.35; 95% CI: 1.03-10.95; p = 0.045). Although patients in the NCH group experienced more major complications (10.5% vs. 4.9%; p = 0.134) and early loss of breast reconstruction (3.9% vs. 0.8%; p = 0.128), these findings were not statistically significant. CONCLUSION This study found no statistically significant association between NCH and higher risk of complications or loss of IBR with LDI after mastectomy.

Abstract
OBJECTIVE The objective of this study was to compare trigger point (TrP) dry needling, TrP electroacupuncture and motor point electroacupuncture of the trapezius muscle for the treatment of myofascial pain syndrome (MPS). METHODS This randomised clinical trial included 90 patients divided into three groups. Group 1 was treated with dry needling of TrPs, group 2 with intramuscular electrical stimulation of TrPs, and group 3 with electroacupuncture of motor points and/or the spinal accessory nerve. Each group received seven treatment sessions. The outcomes were the pain score measured by visual analogue scale (VAS) and quality of life evaluated by the 12-item short form (SF-12) health questionnaire. We compared the pain outcome over serial time points using growth curve analysis methods. RESULTS Participants in the three groups experienced significant improvements in pain scores over time. The average pain level of participants in group 3 across the repeated assessments was 0.98 units lower than in group 1 (mean difference (95% confidence interval (CI) = 1.74-0.23)), p = 0.012). There were no significant differences in pain scores between participants in groups 1 and 2, and there were no significant differences in quality of life across the three groups at the end of the treatment period. CONCLUSION Our results provide evidence that electrical stimulation of motor points and/or of the spinal accessory nerve may be superior in terms of pain relief (but not quality of life) to dry needling and possibly electrical stimulation of trigger points for the management of MPS involving the trapezius. TRIAL REGISTRATION NUMBER TRIAL-RBR-43R7RF (Brazilian Clinical Trials Registry).

Abstract
BACKGROUND Both superior capsular reconstruction (SCR) and middle trapezius tendon (MTT) transfer can be performed in nonarthritic young and active patients with isolated irreparable supraspinatus tendon tears (IISTTs). However, to our knowledge, no comparative clinical studies have been conducted on these procedures. PURPOSE To evaluate and compare the clinical and radiological outcomes of SCR and arthroscopic-assisted MTT transfer in patients with IISTTs. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 60 patients with IISTTs were categorized into 2 groups according to the surgical procedure-Group S underwent SCR (n = 34); Group M underwent MTT transfer (n = 26). The clinical outcomes included the visual analog scale score for pain, active shoulder range of motion, American Shoulder and Elbow Surgeons score, and University of California, Los Angeles, shoulder score. Radiological outcomes included the assessment of the acromiohumeral distance, progression of cuff tear arthropathy (Hamada grade), subacromial bone erosion, and graft failure. RESULTS The mean follow-up time was 39.3 ± 5.2 months (range, 26-59 months) and 37.6 ± 9.8 months (range, 27-54 months) in Group S and Group M, respectively. Significant improvements in clinical outcomes were observed in both groups, while the active forward flexion (148.2°± 24.1° vs 165.9°± 8.7°; P = .003) and abduction (131°± 37.3° vs 152.5°± 17.9°; P = .035) were significantly higher in Group M at the final follow-up. No significant differences were found in the postoperative Constant, American Shoulder and Elbow Surgeons, and University of California, Los Angeles, shoulder scores between the 2 groups. Radiologically, although no difference was found in the Hamada grade at the final follow-up between the 2 groups (P = .143), the rates of acromial wear (58.8% vs 15.4%; P < .001) and graft retear (47.1% vs 7.7%; P < .001) were significantly higher in Group S than in Group M. CONCLUSION Both SCR and MTT transfer improved the overall clinical outcomes of IISTTs postoperatively, whereas MTT transfer was superior to SCR in terms of active forward flexion and abduction range of motion. Although higher rates of graft failure and subacromial bone erosion were observed in Group S, no difference was found in the clinical scores between the 2 groups at the short-term follow-up. However, further well-structured, prolonged comparative trials should be conducted in the future.

Abstract
BACKGROUND This study investigated the epimuscular myofascial force transmission between the levator scapulae, serratus anterior, and rhomboid minor muscles. METHODS The participants included 10 healthy males (a total of 20 shoulders). Differences in the shear moduli of the levator scapulae, serratus anterior, and rhomboid minor muscles were measured in the resting and levator scapulae stretching positions using shear wave elastography. The correlation between the rates of change for each muscle was also verified. FINDINGS The results demonstrated a notable increase in the shear modulus from the resting to stretching positions for levator scapulae (42.9 ± 17.6 kPa vs. 52.4 ± 15.2 kPa) and serratus anterior (32.8 ± 12.9 kPa vs. 58.4 ± 18.5 kPa) (P = 0.02, P < 0.01). However, there was no significant difference in the shear modulus for the rhomboid minor between the resting (44.0 ± 19.2 kPa) and stretching (41.0 ± 20.2 kPa) positions (P = 0.40). Moreover, a significant positive correlation was observed between rates of change for the levator scapulae and serratus anterior muscles (P = 0.04, r = 0.459). INTERPRETATION These findings indicate that the shear modulus of the serratus anterior increased with the stretching of the levator scapulae, suggesting the occurrence of epimuscular myofascial force transmission between these two muscles with different muscle insertions.

Abstract
BACKGROUND Sacrifice of the latissimus dorsi (LD) muscle might entail donor site morbidity when used in delayed breast reconstruction. Previous studies are small, have short follow-up, and demonstrate diverging results. The aims of this study were to evaluate long-term patient-reported effects on shoulder and back function following LD flap harvest, and to investigate predictors for a worse outcome. METHOD This is a retrospective observational case-control cohort study. Cases were all patients who had undergone an LD flap reconstruction during the years 2007-2017. Controls were patients reconstructed with a deep inferior epigastric perforator (DIEP) flap during the same time period. Participants completed two validated questionnaires; the BREAST-Q reconstruction LD domains and the Western Ontario Shoulder Osteoarthritis Index (WOOS). RESULTS A total of 135 cases (75 per cent) and 118 controls (60 per cent) responded to the questionnaires. The mean follow-up time was 7 years. Patients reconstructed with a LD flap were significantly less satisfied with their back and shoulder function when compared to the DIEP controls, as measured with BREAST-Q and WOOS. Predictors for a poor patient-reported back and shoulder function included axillary surgery and axillary radiotherapy, especially when combined, as well as higher age at reconstruction. CONCLUSION Patients who have undergone LD flap for delayed breast reconstruction had a lower satisfaction with back and shoulder function, when compared to patients who had undergone a DIEP reconstruction. Delayed LD reconstruction should be used with care, especially in patients who have undergone axillary surgery and axillary radiotherapy.

Abstract
Musculoskeletal disorders (MSDs) significantly impact workers in the manufacturing and construction sectors. One solution that has gained interest to reduce MSDs incidence is the use of exoskeletons. In this study, the influence of an upper limb exoskeleton on muscle activity was investigated experimentally for three commonly performed tasks in the manufacturing and construction sectors. The tasks tested were overhead assembly, bricklaying, and box moving tasks. Eighteen males participated in the tests. The results showed a reduction in shoulder flexor muscle activation during all three tasks (up to -45.46 ± 4.52% for the anterior deltoid), but increased extensor activation (up to 15.47 ± 8.01% for the latissimus dorsi) was observed when the task was not primarily performed above shoulder level. The results revealed the dependence of the upper-body exoskeleton on tasks and arm posture, which should be considered for both in-field applications and designing new exoskeletons for performance enhancement.

Abstract
Background: The lower trapezius myocutaneous flap (LTF) is a pedicled flap with clinically significant variability of distal skin flap perfusion. Objective: To compare the incidence of partial flap necrosis before and after the institution of routine intraoperative laser-assisted indocyanine green (ICG) angiography. Methods: This is a retrospective review of all LTF performed between November 2021 and July 2022. The outcomes measured in this study are the distance distal to the inferior border of the trapezius muscle with adequate perfusion, and incidence and degree of partial flap necrosis. Results: Sixteen patients met inclusion criteria with a median age of 64.5 years, and a median defect size of 147 cm2. Most patients (11/16) had undergone previous treatment for malignancy. Before utilizing ICG angiography, 40% (2/5) had partial flap necrosis, whereas after utilizing ICG angiography, 9% (1/11) of patients had partial flap necrosis. Seventy-three percent (8/11) of cases who underwent ICG angiography demonstrated a portion of the skin paddle with inadequate perfusion. The range of skin perfusion distal to the inferior border of the trapezius muscle was 0-7 cm (median, 4). Conclusions: The incidence of partial flap necrosis decreased after institution of routine ICG angiography.

Abstract
INTRODUCTION Lymphedema in the upper limb as a complication of breast cancer may lead to shoulder pain and dysfunctions. OBJECTIVE To compare the scapular positioning, the shoulder range of motion, and muscle strength among women undergoing treatment for breast cancer with and without lymphedema and a control group. METHODS This cross-sectional study evaluated women undergoing treatment for breast cancer (N = 25) and without lymphedema (N = 25), and a control group (N = 25). Static scapular positions and shoulder range of motion were measured by using an inclinometer. The shoulder and periscapular muscle strength were measured by using a hand-held dynamometer and the Disabilities of the Arm, Shoulder, and Hand Questionnaire was applied. Linear regression of the mixed effects model was used to compare the groups. RESULTS Both groups of mastectomized women had reduced shoulder range of motion, scapular upward rotation, and muscle strength for shoulder and periscapular muscles compared to the control group. Also, women undergoing treatment for breast cancer with lymphedema had reduced shoulder range of motion, scapular upward rotation, increased anterior tilt, reduced muscle strength of the upper trapezius, and greater upper limb disability compared to women without lymphedema. CONCLUSION Women undergoing treatment for breast cancer with lymphedema had even greater shoulder and scapulothoracic impairments when compared to the control group and women without lymphedema.

Abstract
Motor unit number index of the upper trapezius (MUNIX-Trapezius) is a candidate biomarker for bulbar lower motor neuron function; however, reliability data is incomplete. To assess MUNIX-Trapezius reliability in controls, we conducted a systematic review, a cross-sectional study (n = 20), and a meta-analysis. We demonstrated a high inter- and intra-rater intraclass correlation (0.86 and 0.94, respectively), indicating that MUNIX-Trapezius is reliable with between-study variability moderated by age and MUNIX technique. With further validation, this measure can serve as a disease monitoring and response biomarker of bulbar function in the therapeutic development for amyotrophic lateral sclerosis.

Abstract
Congenital unilateral absence of trapezius is a rare condition, previously reported in cadaveric specimens. It can cause static shoulder asymmetry and affects the scapular biomechanics and functionality, so complete physical examination of the patient becomes important in order to dimiss or suspect an anomaly. We present a case of a 8 years old boy with asymmetry and scapular winging, who was referred to rehabilitation, suspected facioscapulohumeral dystrophy. An MRI scan of cervical spine and shoulder confirmed the absence of the right trapezius muscle. There were no functional disabilities. No other significant congenital anomalies were found.

Abstract
INTRODUCTION Kettlebell exercises, specifically the bottom-up grip, have become increasingly popular in training programs. The purpose of this research was to determine if a bottom-up kettlebell grip favorably alters the electromyography (EMG), activity in the medial deltoid (MD), serratus anterior (SA), and lower trapezius (LT), muscles compared to using a dumbbell or traditional kettlebell grip during overhead shoulder presses. METHODS Twenty-eight healthy, male, Division III collegiate baseball players (mean age = 19.8 ± 1.28 years) performed five overhead presses of equal weight, 11.34 kg (25 lbs), using a dumbbell (DB), kettlebell w/traditional grip (KB), and kettlebell held with a bottom-up grip (KBU). RESULTS For the MD, there was significantly greater EMG activity using the DB compared to KBU, but no significant differences between the DB and KB, or KB and KBU. For the SA, greater EMG activity was noted using the KBU compared to KB, and KBU compared to DB, but no differences between KB and DB. For the LT, greater EMG activity was noted using the DB compared to KB, but no differences between DB and KBU, or KB and KBU. CONCLUSION The KBU press only elicited greater EMG activity in the SA. The DB elicited greater EMG activity in both the MD and LT. Shoulder-complex EMG activity varies with different types of overhead presses using equivalent loads.
