Abstract
BACKGROUND Subcutaneous fat necrosis of the newborn (SCFN) is a rare form of panniculitis manifesting as erythematous plaques or nodules at sites of brown fat in neonates. Surgical management may be indicated in severe cases; however, there is a paucity of literature compiling presentations and outcomes of these surgical patients. METHODS The authors performed a systematic review, in consultation with a licensed librarian, on MEDLINE and Embase for studies including patients with SCFN who were surgically managed. RESULTS The search strategy generated 705 results, among which 213 (30.2%) were excluded for lack of discussion on surgical management. Twenty-two studies discussed surgical management of SCFN in 26 patients, but in 6 of these studies the patients were not surgically managed. Ultimately, 16 articles with 16 patients who were surgically managed were included in the study. Average age at diagnosis was 11.8 ± 9.8 days; average age at surgery was 39.5 ± 70.4 days. The most common etiologies were "unknown" (6, 37.5%), therapeutic hypothermia (4, 25.0%), and birth complications (4, 25.0%). Patients harbored nodules on the back (14, 87.5%), upper extremities (7, 43.8%), lower extremities (7, 43.8%), buttocks (5, 31.3%), and head or neck (3, 18.8%). Linear regression models revealed the presence of back lesions and predicted concomitant medical complications (β = 2.71, p = 0.021). CONCLUSIONS Patients undergoing surgical management for SCFN most commonly harbor lesions on the back and extremities that are secondary to therapeutic hypothermia or of unknown origin. Reporting of additional cases is needed to further elucidate surgical management and outcomes.

Abstract
BACKGROUND Burns that involve the perineum, buttocks and genitals (PBG) have been associated with more challenging therapeutic needs and worse clinical outcomes. We aimed to investigate whether PBG burns are an independent predictor for mortality, morbidity and complications in a large, heterogenous patient collective and in comparison to patients without PBG burns. PATIENTS AND METHODS Patients admitted to a level one burn center between August 2014 and July 2022 were included and stratified based on the presence of PBG burns on admission (PBG & control group = CTR). Demographic baseline data, burn aetiology, inhalation trauma (IHT), full-thickness burns (FT), number of operations (NOR), mortality, length of ICU stay (LOS-ICU), length of in-hospital stay (LOHS) and bacteraemia were assessed to compare key clinical characteristics and outcomes between the groups. Multivariate regression analyses and a 1:1 propensity score matching were conducted for key clinical outcomes. RESULTS A total of 1024 patients were included in the analysis (PBG: n = 227; CTR: n = 797). PBG burns were older (median (IQR) 54 (34-72) vs. 44, (30-61) years, p < 0.0001), more frequently female (35% vs. 23%, p = 0.002) presented with larger total body surface area (TBSA) burns overall (27 (32-39) vs. 10 (13-15) %, p < 0.0001) and sustained FT burns more frequently (69% vs. 26% p < 0.0001). Scald burns were more frequently the cause of PBG burns (45% vs. 15%, p < 0.0001), PBG patients needed twice as many surgical procedures (Mean (SD) 2 (2.84) vs. 1 (1.6), p < 0.0001) as CTR. In multivariate analyses, a significant correlation was identified between length of ICU stay and presence of PBG burns. Following strict cohort matching to account for sex, age, cause of burn, TBSA %, presence of FT burn, inhalation trauma and bacteraemia, PBG burns were an independent predictor for mortality (p = 0.0003). CONCLUSION PBG burns are at risk for prolonged intensive care, hospitalization and complications during treatment. Furthermore, the presence of PBG burns appears to be a risk factor for mortality, irrespective of patient age, TBSA affected and other relevant covariates.

Abstract
BACKGROUND Piriformis muscle mass is rare, which is particular for intrapiriformis lipoma. Thus far, only 11 cases of piriformis muscle mass have been reported in the English literature. Herein, we encountered one patient with intrapiriformis lipoma who was initially misdiagnosed. CASE PRESENTATION The patient is a 50-year-old Chinese man. He complained of osphyalgia, right buttock pain, and radiating pain from the right buttock to the back of the right leg. Both ultrasound and magnetic resonance imaging demonstrated a cyst-like mass in the right piriformis muscle. Ultrasonography-guided aspiration was performed on this patient first, but failed. He was then recommended to undergo mass resection and neurolysis of sciatic nerve. Surprisingly, final histology revealed the diagnosis of intrapiriformis lipoma. The patient exhibited significant relief of symptoms 3 days post-surgery. CONCLUSION Diagnosis and differential diagnosis of radicular pain are potentially challenging but necessary. Atypical lipoma is prone to be misdiagnosed, especially in rare sites. It is notable for clinicians to be aware of the presence of intrapiriformis lipoma to avoid misdiagnosis and inappropriate treatment.

Abstract
CONTEXT Anterior cruciate ligament injuries are directly related to the control of dynamic knee valgus in the landing of a jump, and this is mainly due to the correct activation and neuromuscular function of the lower-extremity muscles. The aim of the study is to assess the relationship between lower limb muscle activity during a single-legged drop jump and knee frontal plane projection angle (FPPA). DESIGN A correlation study. METHODS Thirty healthy collegiate female athletes were included in the study. Main outcomes measures were peak knee FPPA and muscle activity (% of maximal voluntary isometric contraction). Peak knee FPPA during a single-legged drop jump test was identified using a 2-dimensional motion analysis system. Muscle activity was assessed using a surface electromyograph for gluteus maximus, gluteus medius, biceps femoris, semitendinosus, vastus medialis quadriceps, vastus lateralis quadriceps, medial gastrocnemius, and lateral gastrocnemius. All variables were assessed for both dominant and nondominant limbs. A correlation analysis between peak knee FPPA and muscle activity was performed. Statistical significance was set at P <.05. RESULTS A mean peak knee FPPA of 14.52° and 13.38° was identified for dominant and nondominant limb single-legged drop jump test, respectively. Muscle activity (% of maximal voluntary isometric contraction) for muscles assessed ranged from 43.97% to 195.71% during the single-legged drop jump test. The correlation analysis found no significant correlation between any of the muscles assessed and peak knee FPPA during the single-legged drop jump test (Pearson coefficient between -.3 and .1). CONCLUSIONS There is no association between muscle activity from the lower limb muscles and the knee FPPA during a single-legged drop jump in female athletes. Thus, different muscle properties should be assessed in order to understand such an important movement as the knee FPPA during a jump.

Abstract
Objectives. Seated sleep during flight can bring significant discomfort to passengers. The objective of this research was to study passengers' dynamic comfort maintenance strategies in lower limb postural shifting during seated sleep in flight. Methods. Studies on seated sleep postures and sitting comfort were conducted. First, 40 participants were recruited to the observational research for collecting typical leg postures during seated sleep. Then, an experiment was conducted with the participants simulating seated sleep in the aircraft seat. The changes in lower limb edema and seat pressure in different postures were measured with a bioelectrical impedance device, near-infrared spectroscopy device and pressure mapping device. Results. Six postures were selected through the observational research. The experiment showed that tissues of the thighs and buttocks suffer alternate higher compression by shifting between the six postures. Lower limb edema is higher when the shanks are forward, while the tissue under the ischial tuberosity suffers higher compression when the shanks are neutral. Conclusion. Six motivations for passengers to shift each sitting posture to achieve dynamic comfort were summarized, which helps obtain alternating rest in different body parts. The suggestion of a leg position adjustment system was also proposed.

Abstract
BACKGROUND People with degenerative cervical myelopathy are known to have impaired standing balance and walking abilities, but less is known about balance responses during walking. RESEARCH QUESTION The aim of this project was to assess reactive balance impairments during walking in people with degenerative cervical myelopathy (PwDCM). We hypothesized that center of mass motion following perturbations would be larger in PwDCM and gluteus medius electromyographic amplitude responses would be decreased in PwDCM. METHODS Reactive balance responses were quantified during unanticipated lateral pulls to the waist while treadmill walking. Walking biomechanics data were collected from 10 PwDCM (F=6) and 10 non-myelopathic controls (F=7) using an 8 camera Vicon System (Vicon MX T-Series). Electromyography was collected from lower limb muscles. Participants walked on an instrumented treadmill and received lateral pulls at random intervals and in randomized direction at 5% and 2.5% body mass. Participants walked at 3 prescribed foot placements to control for effects of the size of base of support. RESULTS As compared with controls, the perturbation-related positional change of the center of mass motion (ΔCOM) was increased in PwDCM (p=0.001) with similar changes in foot placement (p>0.05). Change in gluteus medius electromyography, however, was less in PwDCM than in controls (p<0.001). SIGNIFICANCE After experimentally controlling step width, people with mild-to-moderate degenerative cervical myelopathy at least 3 months following cervical spine surgery have impaired reactive balance during walking likely coupled with reduced gluteus medius electromyographic responses. Rehabilitation programs focusing on reactive balance and power are likely necessary for this population.

Abstract
BACKGROUND Perinatal running participation has increased recently; however, pregnancy related symptoms can limit activity. Perinatal running biomechanics could inform interventions to help perinatal individuals maintain an active lifestyle. RESEARCH QUESTION Are perinatal running biomaechanics and muscle activation different compared to nulligravida females? METHODS Sixteen pregnant participants completed self-selected velocity running during second trimester (2 T), third trimester (3 T), and postpartum (PP) and 16 matched controls completed these procedures once in this case control study. Kinematic, kinetic, and electromyography (EMG) data were collected using a motion capture system, force plates, and EMG electrodes. Peak trunk, pelvis, hip, knee, and ankle kinematics and hip, knee, and ankle moments during stance phase, and average and peak erector spinae (ES), gluteus maximus (GMax), and gluteus medius (GMed) EMG amplitude and duration of activation during stance and swing phases were calculated. Independent t-tests were used to compare 2 T, 3 T, and PP to control participants (α < 0.05). RESULTS Running velocity was slower during 3 T compared to control participants. At all pregnancy timepoints compared to the control group, peak trunk contralateral rotation was smaller. During 2 T and 3 T peak hip flexor moments were smaller. At 3 T pelvis contralateral rotation was smaller, ES average amplitude was greater during swing, GMax percent duration during stance and GMed percent duration during swing were smaller. At PP trunk flexion was smaller and knee abduction was greater (all p < 0.05). CONCLUSIONS Decreased running velocity may help offset increased demand during pregnancy. During 3 T, greater ES activation, smaller trunk and pelvis motion, and altered gluteal activation could indicate trunk rigidity combined with modified hip stabilizer muscle utilization. During PP, the rigid trunk combined with greater knee abduction may indicate hip and trunk strength deficits. Altered trunk and hip motion and activation could be relevant to pathologies such as perinatal low back, pelvic girdle, or knee pain.

Abstract
Purpose To summarize the clinical, histopathological and therapeutic features of senile gluteal dermatosis. Patients and Methods Retrospective analysis of 230 cases who visited the outpatient clinic of Hangzhou No. 3 People's Hospital for skin lesions on the buttocks and hips from 2018.8-2023.8 were included in the study, basic clinical information was collected, and they were subjected to physical examination of the buttocks and hips, and 36 cases were senile gluteal dermatosis, of which 7 underwent histopathological biopsy. Results A total of 230 patients were included, of which 36 were diagnosed with geriatric buttock dermatosis, with a mean age of (84.2±12.6) years, mean body mass index of (21.7±3.8) kg/m2, and a male to female ratio of 2:1. There was a significant correlation between the occurrence of the disease and age, gender, body mass index, sedentary time, type of chair used, and hypertension (P<0.05). The severity of the lesions may be associated with longer sitting time and prolonged use of bamboo chairs (P<0.05). Histopathologic changes were not specific. The skin lesions could subside after general treatment such as improvement of lifestyle, use of pressure-reducing air mattresses, salicylic acid cream, and moisturizing creams. Conclusion Senile gluteal dermatosis is a common senile physical dermatosis, mainly manifested as brownish scaly plaques, erythema and crusted ulcers, which can often be cured under reasonable treatment.

Abstract
(1) Background: Leg length discrepancy (LLD), regardless of its origin, is a very common pathology that can contribute to low back pain. Various authors have pointed out its relationship with the lack of activation of both the gluteus medius (GM) and the ipsilateral erector spinae (ES). The purpose of this study was to identify the activation of the ES and GM with different simulated LLDs, correlating this activation with LBP. In turn, we evaluated whether ES and GM activity has an effect on jumping ability using a CMJ test. (2) Method: A sample of healthy subjects was selected to whom an artificial LLD was applied using 0.5, 1, and 1.5 cm insoles. These three heights were measured using EMG while the subjects walked and performed a counter movement jump (CMJ). The measurements of the insole heights were carried out in random order using a Latin square. Muscle activation patterns were recorded for 30 s at each of the insole heights while the patients walked at 5.7 km/h and they were compared with the maximum voluntary contraction (MVC), both on the ipsilateral and contralateral sides. These muscles were then measured under the same circumstances during the performance of the CMJ. (3) Results: We found statistically significant differences in the flight heights in both the CMJ and DJ. In the comparison, significant differences were found in the flight heights of the CMJ and the DJ using the 5 mm insoles, and in the case of the DJ, also without insoles, with respect to the MVC. We found statistically significant differences in the activation of the GM with the differences in insoles, but not in the activation of the Es in relation to the different insole heights. (4) Conclusions: Insoles of different heights caused activation differences in the medius on the side where the insoles were placed. We can relate this difference in activation to LBP. In relation to the ES, no significant differences were found in the activation of the ipsilateral side of the insole.

Abstract
PURPOSE Gluteal compartment syndrome (GCS) is a rare but devastating condition with a paucity of literature to help guide diagnosis and management. This study aims to identify and describe the risk factors and patient characteristics associated with GCS to facilitate early diagnosis. METHODS This is a retrospective case series of patients undergoing gluteal compartment release between 2015 and 2022 at an academic Level I trauma center. Chart reviews were performed to extract data on patient demographics, presenting symptoms, risk factors, operative findings, and postoperative outcomes. RESULTS 14 cases of GCS were identified. 12 (85.7%) were male, with a mean age of 39.4 ± 13 years and a mean BMI of 25.1 ± 4.1 kg/m2. 12 (85.7%) patients did not present as traumas and only 3 had ≥ 1 fracture. 9 patients reported drug use. Hemoglobin (Hgb) (11.7 ± 4 g/dL) was generally low (5 had Hgb < 10 g/dL). Creatine kinase (49,617 ± 60,068 units/L) was consistently elevated in all cases, and lactate (2.8 ± 1.6 mmol/L) was elevated in 9. 13 had non-viable muscle requiring debridement. Postoperatively, the mean ICU length of stay was 12 ± 23 days. 2 patients died during admission and all remaining patients required discharge to rehabilitation facilities. CONCLUSION GCS is more likely to present in a young to middle-aged, otherwise healthy, male using drugs who is either found down or experienced an iatrogenic injury. Recognizing that GCS is different from that of the leg, in terms of etiology, may help avoid delays in diagnosis and treatment.

Abstract
This study aimed to evaluate the effect of exhaustive exercise on lumbopelvic-hip complex (LPHC) muscle activity, stability, and single-leg squat kinematics. Twenty-two healthy participants (12 females, 23.5 ± 3.1 years) were recruited. LPHC stability was measured by number of errors committed during a seated trunk control test (STCT). Surface electromyography recorded muscle activity of rectus abdominis (RA), external oblique, internal oblique (IO), erector spinae, and gluteus medius during the STCT and single-leg squat, and was normalized to peak activity during the task. Two-dimensional motion analysis quantified frontal and sagittal plane kinematics of the trunk, hip, and knee. Following exhaustive exercise, STCT performance worsened (number of errors: pre: 5.5 (interquartile range (IQR) = 1.4-9.0), post: 8.0 (IQR = 3.6-11.3), p = 0.026.), RA activity increased during the single-leg squat (pre: 42.1 (IQR = 33.6-48.5)%, post: 61.1 (IQR = 39.4-156.7 %, p =.004), and participants displayed less hip and knee flexion (hip: pre: 72.4 ± 22.1°; post: 66.2 ± 22.5°, p =.049; knee: pre: 72.4 ± 15.4°; post: 67.4 ± 18.2°, p =.005). Full-body exhaustive exercise negatively affected isolated LPHC stability and resulted in greater RA activity during the single-leg squat. Hip and knee flexion decreased during a single-leg squat after exhaustive exercise which could indicate decreased athletic performance, but changes in the quality of movement during other tasks should be further investigated.

Abstract
Patients with knee osteoarthritis (KOA) might have gait deviations, but few previous studies have discussed gait compensatory movements of the proximal and distal parts of muscle groups related to KOA. The study aimed to measure lumbar and hip movements during gait test and collect muscle activities of the lower extremities. Thirty-four participants with KOA and 28 healthy participants aged over 50 years were recruited for this study. Lumbar and hip motions during walking test were measured using inertial measurement units. Four muscle groups of the lower extremity (erector spinae, gluteus maximus, quadriceps muscle, and gastrocnemius) activities in gait were collected using surface EMGs. KOA patients used an 2.12∘anterior inclined lumbar spine (p = 0.007) and 22.94∘ flexed hip (p = 0.001) in gait compared to healthy participants. The KOA patients had a small hip movement range 30.19∘(p = 0.001) and a higher asymmetric stance time ratio 0.39 (p = 0.006). Patients with KOA showed decreased erector spinae and gluteus maximus muscle activation and increased activation of the quadriceps and gastrocnemius muscles during gait. In conclusion, patients with KOA used a hyperlordotic lumbar and hip flexed strategy, which overactivates distal extensor muscles through the whole gait and might cause overstress on the lower extremity joints.

Abstract
PURPOSE The middle cluneal nerve (MCN) is a pure sensory nerve around the middle buttock. Its entrapment between the iliac crest and the long posterior sacroiliac ligament elicits low back pain (LBP) that can be treated by MCN neurolysis or neurectomy. Because few studies examined the pathology of MCN entrapment (MCN-E) we subjected 7 neurectomized specimens from 6 LBP patients to pathologic study. METHODS We present 6 consecutive patients (7 sides) with intractable LBP who underwent successful MCN neurectomy. Their symptom duration ranged from 6 to 96 months (average 47.3 months); the follow-up period ranged from 6 to 17 months (average 11.7 months). The surgical outcomes were evaluated using the numerical rating scale (NRS) for LBP and the Roland-Morris Disability Questionnaire (RDQ) score. The resected MCNs underwent neuropathological analysis. RESULTS Postoperatively, all 6 patients reported immediate LBP amelioration; their NRS and RDQ scores were improved significantly. Pathological study of the 7 resected nerves showed that the myelinated fiber density was decreased in 6 nerves; we observed marked enlargement (n = 5), perineurial thickening and disruption (n = 6), intrafascicular fibrous changes (n = 5), myelinated fibers separated by fibrous cells under the perineurium (n = 4), and Renaut bodies (n = 3). The 7th nerve appeared normal with respect to the density and size of the myelinated fibers, however, the perineurium was slightly thickened. CONCLUSION We present pathological evidence at the MCN compression site of 7 nerves from 6 patients whose LBP was alleviated by MCN neurectomy, indicating that MCN entrapment can elicit LBP.

Abstract
BACKGROUND Calcific tendinitis is classically a painful condition that most commonly affects the rotator cuff, but may infrequently involve other tendons. CASE REPORT We discuss a 57-year-old man who presented to the emergency department with a 4-day history of right hip pain, described as the "worst pain in (his) life." The pain was first noticed at night and had progressively worsened. History, physical examination, and initial laboratory workup indicated an inflammatory vs. infectious process. Continued investigations with imaging techniques revealed the source of pain as calcific tendinitis involving the gluteus maximus tendon. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Symptoms of musculoskeletal pain in the emergency department are ubiquitous. In the proper clinical context, the diagnosis of calcific tendinitis, although uncommon, should be considered once emergent conditions are ruled out. Proper imaging techniques will facilitate accurate diagnosis, expedited pain management, and proper outpatient follow-up.

Abstract
BACKGROUND Cellulite is an aesthetically displeasing rippling or dimpling of the skin, primarily on the buttocks/thighs. A recent study showed a novel acoustic subcision device produced significant short-term (12-week) improvement in the appearance of cellulite after a single rapid acoustic pulse (RAP) treatment. OBJECTIVE To evaluate the long-term (>52-weeks) efficacy and safety of RAP treatment for improvement in the appearance of cellulite. MATERIALS AND METHODS In this prospective, multicenter trial, female participants ( n = 42) with severe cellulite were treated with the acoustic subcision device in a single visit. At >52 weeks, blinded board-certified dermatologists assessed efficacy by correctly identifying post-treatment photographs and using a 6-point simplified Cellulite Severity Scale (CSS). Participant satisfaction was also collected. Safety was assessed throughout. RESULTS The blinded panel correctly identified post-treatment photographs at a rate of 95.2%; 70.4% of participants had a >1-point reduction in the CSS score from baseline (mean reduction of 1.09). All participants (100%) reported improved cellulite appearance. Overall pain during treatment was rated as 2.4 and 0.3 post-treatment (pain scale 0-10). No device or treatment-related adverse events were reported at the >52-week follow-up. CONCLUSION Rapid acoustic pulse treatment significantly improved the long-term appearance of cellulite and was well-tolerated.

Abstract
In the United States, wheelchair cushions are classified using HCPCS codes. Cushions classified as Skin Protection cushions are provided for wheelchair users who are at risk of tissue damage. Cushions designed for bariatric users fall into a category of cushions with width of 22 inches or greater. Current coding procedures require tests that are designed for 41-43-cm-wide cushion so cannot evaluate wider cushions. The objective of this study was to evaluate the performance of heavy-duty or bariatric wheelchair cushions using an anthropometrically appropriate buttock model and loading profile. A rigid buttock model, designed to reflect the anthropometry of persons using cushions over 55 cm in width was loaded onto six bariatric-sized wheelchair cushions. Two applied loads, 75 and 88 kg, represented the 50th and 80th percentile of persons who would be expected to use a 55-cm-wide cushion. None of the cushions indicated a bottomed-out state at the 88 kg load, suggesting that they could adequately support users weighing 135 kg. However, when evaluating cushions at their maximum rated loads, two of the six cushions were approaching or had bottomed-out. This study indicates that a more valid approach to classify Skin Protection bariatric cushions is needed.

Abstract
Advancements in systems for prevention and management of pressure ulcers require a more detailed understanding of the complex response of soft tissues to compressive loads. This study aimed at quantifying the progressive deformation of the buttock based on 3D measurements of soft tissue displacements from MR scans of 10 healthy subjects in a semi-recumbent position. Measurements were obtained using digital volume correlation (DVC) and released as a public dataset. A first parametric optimisation of the global registration step aimed at aligning skeletal elements showed acceptable values of Dice coefficient (around 80%). A second parametric optimisation on the deformable registration method showed errors of 0.99mm and 1.78mm against two simulated fields with magnitude 7.30±3.15mm and 19.37±9.58mm, respectively, generated with a finite element model of the buttock under sitting loads. Measurements allowed the quantification of the slide of the gluteus maximus away from the ischial tuberosity (IT, average 13.74 mm) that was only qualitatively identified in the literature, highlighting the importance of the ischial bursa in allowing sliding. Spatial evolution of the maximus shear strain on a path from the IT to the seating interface showed a peak of compression in the fat, close to the interface with the muscle. Obtained peak values were above the proposed damage threshold in the literature. Results in the study showed the complexity of the deformation of the soft tissues in the buttock and the need for further investigations aimed at isolating factors such as tissue geometry, duration and extent of load, sitting posture and tissue properties.

Abstract
Maintaining a vacuum when applying negative pressure wound therapy (NPWT) is the key to its function, which is a challenge in the perineum, buttocks, and sacrococcygeal region. A retrospective cohort study was conducted to assess the effect of hydrocolloid dressings on preventing air leakage when applying NPWT in these regions. There were 61 patients in Group A (without the aid of hydrocolloid dressings) and 65 patients in Group B (with the aid of hydrocolloid dressings). The hydrocolloid dressing-assisted NPWT significantly reduced the incidence of air leakage compared with conventional NPWT placement (24.6% vs. 7.7%; risk ratio, 3.20; 95% confidence interval, 1.24-8.27; p = 0.009), while decreasing the number of open NPWT applications (2.2 vs. 1.7; difference, 0.43; 95% confidence interval, 0.19-0.66; p < 0.001), shortening hospital stays (20.1 vs. 16.1; difference, 4.07; 95% confidence interval, 1.68-6.46; p = 0.01), and reducing the incidence of adverse skin events (18.0% vs. 4.6%; risk ratio, 3.91; 95% confidence interval, 1.14-13.34; p = 0.017). These findings support the routine use of hydrocolloid dressing-assisted NPWT placement in the perineum, buttocks, and sacrococcygeal region.

Abstract
Stress urinary incontinence presents a condition not only found in female elderlies, but also in young athletes participating in high-impact sports such as volleyball or trampolining. Repeated jumps appear to be a predisposing factor. Yet the pathophysiology remains incompletely elucidated to date; especially with regard to the influence of the surrounding buttock tissues including gluteus maximus. The present study assessed the morpho-mechanical link between gluteus maximus and the pelvic floor female bodies. 25 pelves obtained from Thiel embalmed females were studied in a supine position. Strands of tissues connecting gluteus maximus with the pelvic floor obtained from 20 sides were assessed mechanically. Plastinates were evaluated to verify the dissection findings. In total, 49 hemipelves were included for data acquisition. The fascia of gluteus maximus yielded connections to the subcutaneous tissues, the fascia of the external anal sphincter and that of obturator internus and to the fascia of the urogenital diaphragm. The connection between gluteus maximus and the urogenital diaphragm withstood an average force of 23.6 ± 17.3 N. Cramér φ analyses demonstrated that the connections of the fasciae connecting gluteus maximus with its surroundings were consistent in the horizontal and sagittal planes, respectively. In conclusion, gluteus maximus is morphologically densely linked to the pelvic floor via strands of connective tissues investing the adjacent muscles. Though gluteus maximus has also been reported to facilitate urinary continence, the here presented morpho-mechanical link suggests that it may also have the potential to contribute to urinary stress incontinence. Future research combining clinical imaging with in-situ testing may help substantiate the potential influence from a clinical perspective.

Abstract
The purpose was to compare the electromyographic (EMG) activity of the Hang Power Clean (HPC) and Hang Power Snatch (HPS) with the Hang Clean Pull (HCP) and Hang Snatch Pull (HSP). Additionally, the influence of weightlifting expertise (beginner, advanced and elite) on EMG activity was analyzed. Twenty-seven weightlifters (beginner: n = 11, age: 23.9 ± 3.2 years, bodyweight: 75.7 ± 10.5 kg; advanced: n = 10, age: 24.8 ± 4.5 years, bodyweight: 69.4 ± 13.9 kg; elite: n = 6, age: 25.5 ± 5.2 years, bodyweight: 75.5 ± 12.5 kg) participated in this study. Participants performed two repetitions of HPC, HPS, HCP, and HSP at 50%, 70%, and 90% 1RM, respectively. The EMG activity of vastus lateralis (VL), gluteus maximus (GM), erector spinae (ES), rectus abdominis (RA) and trapezius (TZ) was recorded and normalized to the maximum voluntary isometric contraction (MVIC) of each muscle. There were significant differences in RA and ES EMG activity at 70% and 90% 1RM during HPC compared to HCP in the beginner group (p < 0.05, Hedges g = 0.50-1.06). Significant greater ES activity was observed in the beginner, advanced, and elite groups (p < 0.05, g = 0.27-0.98) during the HPS when compared to the HSP at 50-90% 1RM. TZ muscle activity was significantly greater at 50% and 70% 1RM in the HCP compared to the HPC in the elite group (p < 0.05, g = 0.61-1.08), while the beginner group reached significance only at 50% 1RM favoring HPC (p < 0.05, g = 0.38). Moreover, the EMG activity of the TZ during the HSP and HPS was significantly different only at 50% 1RM in the elite group and favored HSP (p < 0.05, g = 0.27). No differences were observed between the levels of weightlifting expertise. Based upon the results of this study, the overall pattern of EMG activity of the predominant muscles involved in HPC/HPS and the corresponding weightlifting pulling derivatives, apart from the stabilizing muscle (RA and ES), is similar at higher intensities (>70% 1RM) and expertise does not influence muscle activity.

Abstract
BACKGROUND Mpox, previously known as monkeypox, -is an orthopoxvirus infection of the skin and previously a public health emergency of international concern. It reemerged in Nigeria over 5 years ago and has since spread to other parts of the world. This is a case report of a confirmed patient who was managed at Irrua Specialist Teaching Hospital, Irrua, Edo State, Nigeria before the global surge. This report shows peculiar differences from previous patients managed at the same center in terms of the relatively prolonged eruptive phase, possible seasonal occurrence of mpox in the community, and some traditional care for mpox and skin rashes. It also corroborates previous reports of possible sexual transmission of mpox in Nigeria before the report from the global outbreak. CASE PRESENTATION The patient is a 30-year-old Nigerian male artisan with a 2-month history of raised rashes on the body that started on the genitals then involved other parts of the body. There was history of sore throat and unprotected sex with a female partner with similar rash whose other sexual history could not be ascertained. There was also history of "seasonal" rash in his village for about 7 years prior to his symptoms. Examination showed multiple vesicles and some nodules (ulcerating, healing, and healed) on the face, trunk, limbs, gluteal region, scrotum, palms, and sole, an almost circumferential penile ulcer, and lymphadenopathy. Polymerase chain reaction skin samples sent for mpox returned positive, while retroviral and coronavirus disease 2019 screenings were negative. He was managed in isolation while contact tracing in the affected community was initiated. CONCLUSION Atypical presentations of mpox, as managed in Irrua before the global surge, emphasize the varied spectrum of presentations (typical and atypical) in Nigeria. Therefore, there is a need for a higher index of suspicion for the uncommon presentations which will strengthen case recognition, case management, and community-based interventions as well as surveillance in the prevention and control of mpox in Irrua, its environs, Nigeria, and the world.

Abstract
OBJECTIVES To measure buttock pressure during toilet seating in persons with spinal cord injury (SCI). DESIGN A case series study. SETTING Kibikogen Rehabilitation Center for Employment Injuries. METHODS The study included 41 persons with SCI. Buttock pressure was measured during toilet seating, with or without a toilet seat cushion (foam cushion, gel cushion, air cushion) on the toilet seat. RESULTS The subjects were classified into three groups according to the site of the maximum pressure [greater trochanter (GT) region, ischial tuberosities (IT), and sacral region (SR)] recorded on the pressure map of the non-cushioned toilet seat, into the GT, IT and SR groups, respectively. All three types of cushions altered the buttock pressure distribution during no-cushion toilet seating. In the GT group, all three cushions significantly reduced the peak pressure in the GT area, compared to the control (no-cushion). The foam cushion significantly increased the peak pressure in the IT area (Pisch) in the GT group, relative to the control. However, the foam cushion significantly increased while the gel cushion significantly reduced Pisch, relative to the control. In SR group, the air cushion significantly reduced the peak pressure in the SR, relative to the control. CONCLUSION We recommend the use of the gel cushion for the IT group and the air cushion in GT and SR group to reduce buttock pressure during toilet seating in persons with SCI.

Abstract
INTRODUCTION Investigating the possible relationship between neuromuscular changes and movement alterations could help to describe the mechanisms underlying patellofemoral pain (PFP). OBJECTIVE To investigate whether activation and muscle strength of the trunk and lower limb and muscle resistance of the trunk predict the knee frontal and trunk sagittal kinematics in women with and without PFP. METHOD Sixty women (PFP, n = 30; asymptomatic, n = 30) underwent the single-leg squat test to collect electromyographic and kinematic data. Activation of transversus abdominis/internal oblique, gluteus medius (GMed), and vastus medialis oblique (VMO); knee frontal and trunk sagittal angles were analyzed. Participants also underwent maximal isometric tests to determine lateral trunk, hip abductor, and knee extensor torques and performed a lateral trunk resistance test. Multiple regression was used to determine predictive models. RESULTS In the PFP group, knee frontal angle (R2 = 0.39, p = 0.001) was predicted by GMed activation (β = 0.23, p = 0.000) and hip abductor torque (β = 0.08, p = 0.022). No variable was able to predict trunk sagittal kinematics in this group. In the asymptomatics, knee frontal angle (R2 = 0.16, p = 0.029) was predicted by hip abductor torque (β = 0.07, p = 0.029), while trunk sagittal angle (R2 = 0.24, p = 0.024) was predicted by VMO activation (β = 0.12, p = 0.016). CONCLUSION Kinematics is predicted by the muscles acting in the respective planes, such that hip abductors capacities are related to the knee frontal alignment in both groups, and that of the VMO is related to the trunk sagittal alignment only in asymptomatic women.

ABSTRACT Goodman, WW, Helms, E, and Graham, DF. Individual muscle contributions to the acceleration of the center of mass during the barbell back squat in trained female subjects. J Strength Cond Res 37(10): 1947-1954, 2023-The squat is used to enhance performance and rehabilitate the lower body. However, muscle forces and how muscles accelerate the center of mass (CoM) are not well understood. The purpose was to determine how lower extremity muscles contribute to the vertical acceleration of the CoM when squatting to parallel using 85% one-repetition maximum. Thirteen female subjects performed squats in a randomized fashion. Musculoskeletal modeling was used to obtain muscle forces and muscle-induced accelerations. The vasti, soleus, and gluteus maximus generated the largest upward accelerations of the CoM, whereas the muscles that produced the largest downward acceleration about the CoM were the hamstrings, iliopsoas, adductors, and tibialis anterior. Our findings indicate that a muscle's function is task and posture specific. That is, muscle function depends on both joint position and how an individual is interacting with the environment.

Abstract
OBJECTIVE the aim of the current study was to compare the lower limb muscle activation pattern in soccer players with and without lumbar hyperlordosis during single-leg squat performance. METHODS thirty male collegiate soccer players (15 with and 15 without lumbar hyperlordosis) performed the SLS task. Surface EMG was used to record the activation of eleven lower limb muscles. The activation of these muscles reduces to 100 points during the SLS cycle, where 50% demonstrates the maximum knee flexion, and 0% and 99% demonstrate the maximum knee extension. RESULTS soccer players with lumbar hyperlordosis had higher muscle activation than those with normal lumbar lordosis in gluteus maximus, biceps femoris, and medial gastrocnemius. By contrast, they had lower gluteus medius, vastus medialis oblique, rectus femoris, soleus, and medial gastrocnemius (only in the final ascent phase of the SLS) muscle activity than the normal group during the SLS. CONCLUSION this alteration may negatively affect targeted muscle performance during the SLS. Subsequent study is required to specify whether such an alteration in the lower limb muscle could be accompanied by injury in soccer players and change in their athletic performance.

Abstract
This study aimed to determine which muscle the gluteus maximus, gluteus medius, gluteus minimus (Gmin), or tensor fasciae latae (TFL) contributes most to hip abduction strength and to identify effective sites for cross-sectional area (CSA) Gmin and TFL measurement in hip osteoarthritis (OAhip) patients. Twenty-eight patients with OAhip were included. The muscle CSA and volume were determined using magnetic resonance imaging. Peak isometric strength was determined using hand-held dynamometry. Muscle volumes were normalized to the total muscle volume of hip abductors. Multiple regression analysis was performed. The difference between the CSA of Gmin and TFL was calculated, and correlations with volume and muscle strength were determined. Gmin volume was related to abductor muscle strength (p=0.042). The peak CSA of the Gmin correlated with muscle volume and strength. The CSA of the TFL correlated with volume, with no difference between the CSA of the most protruding part of the lesser trochanter and peak CSA. Gmin volume was strongly related to abductor muscle strength. Peak CSA is a useful parameter for assessing the CSA of the Gmin among patients with OAhip. The CSA of the TFL should be measured at the most protruding part of the lesser trochanter.

Abstract
The study aimed to investigate the presence of directional preference using the Clinical Pilates method of clamshell exercise among relatively healthy young adults, and the influence of hip flexion angles on maximum isometric strength (handheld dynamometer) and muscle activities (electromyography). The clamshell assessment involves testing in varying angles of hip flexion (0°, 30°, 60° and 90°) and 21 participants were tested. Directional preferences in the transverse and anteroposterior axes of movements were present among the participants. Gluteus medius activation was highest in the non-problem side across all hip flexion angles. In contrast, the problem side showed dysfunction of the gluteus medius, especially at the 60° hip flexion angle, 0.89 unit (ratio of maximal voluntary isometric contraction) reduction per 1 N force exerted, 95% CI -1.69 to -0.09, p = 0.031. Comparison against the non-problem side found gluteus medius activity lower on the problem side, mean difference (SD) was 26.2 (56.1), p = 0.045. Therefore, directional preference is not limited to people with injuries and can exist in healthy individuals or people who have recovered from injuries. The gluteus medius was identified to be dysfunctional on the problem side and Clinical Pilates clamshell assessment is potentially useful in assessing for motor coordination impairment.

Abstract
ABSTRACT Marchetti, PH, Gomes, WA, Da Silva, JJ, Magalhaes, RA, Teixeira, LFM, and Whiting, WC. Backseat inclination affects the myoelectric activation during the inclined leg press exercise in recreationally trained men. J Strength Cond Res 37(10): e541-e545, 2023-Changes in the angle between the seat and backrest during the inclined leg press (ILP) exercise may influence myoelectric activity. The purpose of this study was to evaluate the myoelectric activity between 2 different angles between the seat and backrest (90° and 125°) during the ILP exercise in recreationally trained men. Fifteen young, resistance-trained men (age: 26.8 ± 5.3 years, height: 173.8 ± 6.6 cm, total body mass: 81.6 ± 7.6 kg) performed 1 set of 10 repetitions at 70% of their body mass during the ILP exercise using 2 different angles between the seat and backrest (ILP90° and ILP125°). Surface electromyography (peak RMS 90 and iEMG) was used to measure the myoelectric activity of the vastus lateralis (VL), biceps femoris (BF), and gluteus maximus (GM). A paired t test was used to measure differences in knee and hip joint displacement, peak RMS 90 , and iEMG between ILP90 and ILP125. The hip angle presented a greater displacement during the ILP125 when compared with ILP90 ( p < 0.001), considering a similar knee joint displacement. For the VL, there was observed greater myoelectric activation (peak RMS 90 and iEMG) during ILP125 when compared with ILP90 ( p < 0.05). For the BF, there was observed greater myoelectric activation (peak RMS 90 and iEMG) during ILP90 when compared with ILP125 ( p < 0.05). However, GM did not present differences between ILP90 and ILP125. In conclusion, the angle between the seat and backrest (ILP90 or ILP125) altered the myoelectric activation of the VL and BF with no difference for the GM.

Abstract
Sussex cattle breed is characterized by their distinctive solid red coat colour and white tail switch. Sussex cattle are known for being easy to handle and manage, making them an ideal choice for cattle farmers. The phenotypic characterization of this cattle breed in South Africa is unknown. Hence, the objective of this study was to characterize the morphological structure, phenotypic and body indices traits of Sussex cattle in South Africa at Huntersvlei farm, Frere State province of South Africa. One hundred and one weaners (n = 101) between 6 and 8 months old (female = 57 and male = 44) and fifty yearlings between 12 and 15 months old (female = 15 and male = 35) were used in this study. Body weight at weaning, yearling and linear body measurements such as head length (HL), head width (HW), ear length (EL), ear width (EW), sternum height (SH), withers height (WH), heart girth (HG), hip height (HH), body length (BL), rump length (RL), and rump width (RW) were measured. Moreover, the animals were assessed for coat colour and horn presence. Descriptive statistics, Pearson's correlation and Principal Component Analysis (PCA) were used to describe the Sussex cattle breed. The results indicated that male Sussex cattle had highly significant (p < 0.01) mean numeric values for the BW and morphometric traits. The results further showed that Sussex cattle had highly significant (p < 0.01) increase for the BW and morphometric traits as age advances in all sexes. Interaction effect of sex and age showed a highly significant (p < 0.01) effect with BW and measured morphometric traits, while moderately significant (p < 0.05) with EW. Male Sussex cattle showed highly significant (p < 0.01) higher mean numeric values for the body index (BI), length index (LI) and compact index (CI) indices. While female Sussex animals showed highly significant (p < 0.01) mean numeric values for area index (AI) and proportionality (PR). Body weight showed a positive highly significant (p < 0.01) correlation with the measured morphometric traits except for the moderate significant (p < 0.05) correlation with EL. Coat colour traits ranged from 15 (9.93%), 103 (68.21%) to 33 (21.85%) for light, moderate and dark colours, respectively. While horn presence traits ranged from 48 (31.79%), 42 (27.81%) to 61 (40.40%) for polled, scur and horned respectively. The PCA results extracted only two components in both sexes of the animals. The morphological variations obtained in this study could be complemented by performance data and molecular markers of single nucleotide polymorphism (SNP) to guide the overall breed characterization, conservation and development of appropriate breeding and selection strategies.

Abstract
PURPOSE Entrapment of the middle cluneal nerve (MCN-E) can elicit low back pain (LBP). Patients whose LBP responds only transiently to the analgesic effects of MCN blockage may be candidates for surgery. This study addresses its long-term efficacy. METHODS We initially subjected 34 MCN-E patients (48 sides) to surgical release. Of these, 4 were excluded from this study because their follow-up was shorter than 24 months. The mean age of the 30 included patients was 71.5 years; the mean postoperative follow-up period was 40.4 months. Clinical outcomes were assessed on the Numerical Rating Scale (NRS) for LBP and the Roland Morris Disability Questionnaire (RDQ) before surgery and at the latest follow-up visit. RESULTS The 30 patients (44 sides) reported severe LBP, leg symptoms were elicited by 32 sides. A mean of 1.4 MCN branches were surgically released, 32 sides were addressed by neurolysis, 7 by neurectomy, and 5 underwent both procedures due to the presence of 2 nerve branches. There were no complications. In the course of a mean follow-up of 26.3 months, MCN-E elicited recurrent symptoms on 6 sides; all had undergone neurolysis or neurectomy and a second operation improved the symptoms. All patients showed significant improvement at the last follow-up visit. Postoperatively both their NRS for LBP and their RDQ scores were improved (pre- vs. postoperative scores, p < 0.05). CONCLUSIONS While surgical release of MCN-E is expected to yield long-term symptom relief, on 6 of 32 sides (18.8%) treated by neurolysis the patients reported pain recurrence. Whether neurectomy effectively prevents the recurrence of MCN-E in the long term requires further study.

Abstract
AIMS To determine adverse effects of ventrogluteal intramuscular injections versus dorsogluteal intramuscular injections. DESIGN A systematic review and meta-analysis. METHODS MEDLINE, EMBASE, CINHAL, CENTRAL, LILACS(BVS), BDENF (BVS), WoS, IRCTP(WHO), ClinicalsTrials.gov and PROSPERO databases were searched with no restriction on year or language. Preferred Reporting items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. RESULTS A total of 1429 participants from 17 studies were included. The meta-analysis found that ventrogluteal injection site had significant relation to lower pain in 9 studies (SMD = -0.63, 95% CI = -0.87, -0.39), bleeding in 4 studies (SMD = -3.46, 95% CI = -6.07, -0.86) and hematoma in 2 studies; after 48 h (SMD = -0.25, 95% CI = -0.39, -0.11), and after 72 h (SMD = -0.16, 95% CI = -0.26, -0.06), if it was compared with dorsogluteal site injection. No differences were found when comparing the possibility of intramuscular injections given into de subcutaneous tissue. In three studies, ventrogluteal site did not significantly reduce the risk of subcutaneous injection (OR 0,62, 95% CI = 0.16, 2.41).

Abstract
Pilonidal disease is an acquired disease caused by infected hair follicles imbedded in the midline gluteal area. The diagnosis is made based on clinic examination. Treatment is based on disease severity with minimal invasive techniques like the Bascom I procedure, Moshe Gibs procedure, or video-assisted pilonidal sinus ablation best suited for less complicated cases. However, for recalcitrant diseases, more advanced techniques are needed such as the Karydakis, Limberg, or V-Y advancement flaps.

Abstract
Acute compartment syndrome is a surgical emergency that, if unrecognised, leads to tissue and muscle ischaemia, necrosis, multi-organ failure and even death. Gluteal compartment syndrome is a rare type of compartment syndrome that typically occurs as a sequela of trauma, and its presentation may be difficult to recognise. We describe a case of a patient who developed gluteal compartment syndrome following a prolonged renal surgery in lateral decubitus position. Our case report aims to raise clinicians' awareness to consideration of this rare syndrome in patients presenting with lower extremity or back pain after prolonged surgery.

Abstract
OBJECTIVES Compare lower extremity muscle volume in females with patellofemoral pain (PFP) to a cohort of pain-free females and investigate the relationship between thigh and hip muscle volume and torque. DESIGN Cross-sectional. PARTICIPANTS Twenty-one females, 13 with PFP and 8 pain-free controls. MAIN OUTCOME MEASURES We quantified normalized lower extremity muscle volume (cm3/kg*m) via magnetic resonance imaging and isometric hip and thigh torque (Nm/kg) via a multimodal dynamometer. RESULTS Versus pain-free individuals, females with PFP had smaller muscle volume of the anterior hip (P < 0.019; d = 0.97-2.42), deep external rotators (P < 0.006; d = 1.0-3.93), hamstrings (P < 0.009; d = 1.09-2.12), rectus femoris (P < 0.001; d = 1.79), and vastus intermedius (P < 0.001; d = 1.88). There was no difference in muscle volume of the gluteus maximus (P = 0.311; d = 0.22), gluteus medius (P = 0.087; d = 0.87), vastus lateralis (P = 0.22; d = 0.39), and vastus medialis (P = 0.47; d = 0.04). Gluteus maximus volume was moderately correlated to hip abduction torque (r = 0.60; P = 0.03). Vasti muscles and semitendinosus volume were moderately correlated to knee extension (r = 0.57-0.69; P < 0.05) and flexion (r = 0.66; P = 0.01) torque, respectively. CONCLUSION Females with PFP present with lesser thigh and hip muscle volumes, with variability in volumetric profiles across participants. Lower extremity knee extension and hip abduction strength are moderately associated with the vasti and gluteus maximus muscle volume, respectively.

Abstract
OBJECTIVE Walkers are actively used to improve gait ability in patients with incomplete spinal cord injury (ISCI). This study aimed to investigate the immediate effect of weight load during walker gait training on lower limb muscle activity and gait ability in patients with ISCI using a dependence feedback walker (DFW). DESIGN A single group cross-sectional design. SETTING Local rehabilitation hospital. PARTICIPANTS Fourteen patients with ISCI (62.00 years, Onset duration: 20.57months). INTERVENTIONS The DFW was used to measure the change in lower limb muscle activity and gait ability on walker dependence during the 20-meter walk. Based on the initial measurement of walker dependence, three levels of walker dependence threshold were set (100%, 60%, and 20%). If the weight loaded on the walker exceeded the three threshold levels of walker dependence, auditory and visual feedback was generated. OUTCOME MEASURES During the 20-meter walk, changes in both lower limb muscle activity (rectus femoris, biceps femoris, medial gastrocnemius, tibialis anterior, and gluteus medius) and gait ability (velocity, cadence, and single-limb support phase) were measured by surface electromyography and 3-axis accelerometer. RESULTS The increase in lower limb muscle activation and improvement of gait ability were greater during 20% walker dependence gait training than during 100% walker dependence gait training (P < 0.05). CONCLUSION Reduction of walker dependence by extrinsic feedback generated via DFW during walker gait training may lead to increased lower limb muscle activity and improved gait. These results could be useful for successful self-gait training and improving walking independence in patients with ISCI.

Abstract
Background and Objectives: Surgical management of local recurrence of soft tissue sarcomas (STS) is still challenging. In this article, we report on multiple flap reconstructions for multiple local recurrences of STS. Their feasibility will be validated by examining clinical cases. Materials and Methods: Patients who underwent multiple flap reconstructions for multiple local recurrences of STS between April 1997 and October 2021 were included in this retrospective study. Patient demographics, tumor characteristics, surgical characteristics, and postoperative complications were examined. Results: Twenty operations of eight patients were identified. The location of the defects was the back in two, the buttock in two, the groin in two, and the lower extremities in two. The average total number of wide resections was 4.0 and the average total number of flap reconstructions was 2.5. The average follow-up period was 109.4 months. The average size of the defect was 102.4 cm2 and the average flap size was 15.7 × 10.8 cm. The histological diagnoses were malignant fibrous histocytoma (MFH) in eight operations, osteosarcoma in two operations, myxoid liposarcoma in two operations, undifferentiated pleomorphic sarcoma (UPS) in six operations, and myxofibrosarcoma (MFS) in one operation. Of twelve subsequent operations, the resection of the previously transferred flap was performed in six operations (50%). The occurrence of take back, flap complications, and donor-site complications in the primary operation group was 25%, 25%, and 12.5%, respectively. The occurrence of take back, flap complications, and donor-site complications in the second and subsequent operation group was 0%, 0%, and 16.7%, respectively. Conclusions: Multiple operations including wide resections followed by flap reconstructions for multiple local recurrences are feasible. Reconstructive surgeons should choose the options of the flaps considering the future local recurrence for tumors with a high risk of recurrence.

Abstract
BACKGROUND Tai Chi is an excellent traditional Chinese physical fitness exercise, and its unique balancing movements are very important for improving human balance. In this study, the two most representative Tai Chi balance movements, "knee lift balance" and "leg stirrup balance", were selected to establish the lower limb bone muscle model of Tai Chi balance movements by using computer simulation modeling technology, aiming to analyze the characteristics of the lower limb movement mechanisms of typical balance movements, to provide a quantitative theoretical basis for improving the scientific level of Tai Chi. METHOD A total of 16 subjects were recruited for this study. the BTS three-dimensional motion capture system and three-dimensional force platform were used for motion data acquisition, the physiological electromyographic signals were collected using BTS surface electromyography, and the lower limb bone muscle model of Tai Chi balance movements was established by AnyBody human simulation. RESULT In the knee lift balancing movement, the balance leg hip abduction/adduction angle, hip flexion/extension moment, and the strength of the rectus femoris muscle, biceps femoris short capitis, and iliacus muscle of the amateur group was significantly smaller than that of the professional group (P < 0.01). In the leg stirrup balance movement, the knee flexion/extension angle of the balancing leg in the amateur group was significantly greater than that in the professional group (P < 0.01), and the hip flexion/extension angle, hip inversion/abduction angle, knee flexion/extension moment, hip flexion/extension moment, the strength iliacus, gluteus maximus, and obturator internus were significantly smaller than those in the professional group (P < 0.01). The integral EMG of the biceps femoris of the support leg in the amateur group was significantly smaller than that of the professional group (P < 0.01). The integral EMG of the lateral femoral muscle of the balance leg was significantly smaller than that of the professional group (P < 0.01). CONCLUSION In this study, we found that the balancing leg of the balancing movement has a larger hip joint angle, the stirrup balancing knee joint angle is smaller, and the hip and knee joint moments are larger. This is related to joint activity and muscle activation, and amateurs should pay attention to increasing the range of motion of the hip joint and decreasing the range of motion of the knee joint when practicing to better stimulate exercise of the lower limb joints. In addition, the practice of balancing movements should strengthen the iliacus muscle, which plays an important role in maintaining the stable balance of the lower limbs, and strengthen the knee flexor and extensor muscles and hip adductor/abductor muscles of the balancing leg, thus promoting the stability of the balancing leg movements.

Abstract
OBJECTIVES Single-leg (SL) tasks are included as assessment and intervention strategies in several dysfunctions due to the inherent motor control requirement. The recruitment of gluteus maximus (GMAX) and medius (GMED) muscles is essential for proper biomechanical control of the knee and hip joints. The study aims to identify the role of gluteal activation in the biomechanical control of the lower limb during SL tasks. METHODS This is a systematic review with searches performed in Pubmed, CINAHL, MEDLINE, Web of Science, and Sportdiscus databases. Cross-sectional studies carried out with asymptomatic individuals were selected, containing hip and knee kinematic and kinetic outcomes assessed through 3D or 2D movement analysis and EMG activity of GMED and GMAX muscles. Two independent reviewers performed the procedures to select the studies, determine the methodological quality and extract the data. RESULTS The initial search resulted in 391 studies, and after the assessment procedures, 11 studies were included. Lower GMAX activation was associated with greater hip internal rotation (HIR) excursion and greater HIR moment, and lower GMED activation was associated with greater hip adduction (HAD)/knee abduction (KAB) excursions and greater KAB moment during single-leg squat (SLS). CONCLUSIONS The SL tasks showed a relevant association between the gluteal EMG and other biomechanical outcomes, mainly the SLS task. Interpretation must be cautious, as most studies present high and moderate methodological quality, especially on kinetic data.

Abstract
Individuals with neuromuscular deficits often walk with wider step widths compared to healthy adults. Wider steps have been linked to a higher destabilizing frontal-plane external moment and greater range of frontal-plane whole-body angular momentum (HR), which is an indicator of decreased balance control. The purpose of this study was to experimentally determine 1) how step width alters balance control during steady-state walking, and 2) if step width changes the balance response strategies following mediolateral surface perturbations in healthy adults. Fifteen healthy young adults (7 male, age: 25 ± 4 years) walked on an instrumented treadmill at narrow, self-selected, wide and extra-wide step widths. During perturbed trials, the treadmill provided random mediolateral surface translations to each foot midway through single-leg-stance. Muscle electromyography, biomechanical measures (HR, frontal-plane external moment and joint moments) and deviations (differences in these measures between the perturbed and unperturbed walking trials) were compared across step widths. During steady state walking, wider steps were associated with decreased balance control. Increasing step widths were also associated with increased gluteus medius activity and reduced hip abduction and ankle inversion moments, which suggests healthy subjects rely more on a lateral ankle strategy to maintain balance at increasing step widths. There was no change in the plantarflexion moment. During perturbed walking, lateral, but not medial, surface translations adversely affected balance control. Further, wider steps did not change the balance response strategies following the perturbations, which suggests healthy individuals have the capacity to respond similarly to the perturbations at different step widths.
