Electrical neuromodulation of spinal networks improves the control of movement of the paralyzed limbs after spinal cord injury (SCI). However, the potential of non-invasive spinal stimulation to facilitate postural trunk control during sitting in humans with SCI has not been investigated. We hypothesized that transcutaneous electrical stimulation of the lumbosacral enlargement can improve trunk posture. Eight participants with non-progressive SCI, C3-T9, AIS A or C, performed different motor tasks during sitting...

Feng Xu, Nicholas C Bambakidis
In anterosuperior-projecting anterior communicating artery (ACoA) aneurysms, the aneurysm dome usually adheres to one or both proximal A2 segment, which may present technical difficulties. This video demonstrates microsurgical clipping of a ruptured anterosuperior-projecting AComA aneurysm. A 52-year-old male presented with a Hunt-Hess grade II subarachnoid hemorrhage (SAH). Computed tomography showed SAH in the basal cisterns, sylvian and interhemispheric fissures. Angiography demonstrated a wide-necked AComA aneurysm projecting anterosuperiorly...

Recently, an equation that allows investigators to correct echo intensity for subcutaneous fat was developed. We evaluated correlations between uncorrected and corrected echo intensity versus measures of lower-extremity function. Twenty-three older adults (11 men, 12 women; mean age = 72 y) participated. B-Mode ultrasonography was used to quantify rectus femoris echo intensity and subcutaneous fat thickness. Knee extensor isometric peak torque and rate of torque development at 200 ms (RTD200) were determined (joint angle = 90°)...

BACKGROUND:  Microvascular reconstruction of the anterior cranial fossa (ACF) creates difficult challenges. Reconstructive goals and flap selection vary based on the defect location within the ACF. This study evaluates the feasibility and reliability of free tissue transfer for salvage reconstruction of low, middle, and high ACF defects. METHODS:  A retrospective review was performed. Reconstructions were anatomically classified as low (anterior skull base), middle (frontal bar/sinus), and high (frontal bone/soft tissue)...

Mutations of the encoding genes of collagen VI (COL6A1, COL6A2 and COL6A3 ), are responsible for two classical phenotypes (with a wide range of severity), the Ullrich congenital muscular dystrophy (UCMD) and the Bethlem myopathy (BM). We present a male patient of 49 years old, with symptoms of muscle weakness beginning in childhood and of very slowly progression. At the age of 42, the neurological examination revealed proximal lower limb muscle weakness and contractures of fingers flexors muscles, positive Gowers manoeuvre and a waddling gait...

To improve poor oncological outcomes of conventional abdominoperineal excision (APE), an extralevator abdominoperineal excision has been developed. This technique is associated with a larger pelvic floor defect and needs position changing and flap reconstruction, which increase operating time and morbidity without proof of best oncological results. Based on the recent development of transanal approaches for retrograde transanal mesorectal excision, we describe a novel approach for APE by a primary perineal dissection...

A rugby scrum's front row must act uniformly to transfer maximal horizontal force and improve performance. This study investigated the muscle activation patterns of lower extremity muscles in front row forwards during live and machine scrums at professional and amateur levels. Electromyography was collected bilaterally on vastus lateralis, rectus femoris and gastrocnemius muscles of 75 male rugby prop players during live and machine scrums. ANOVAs compared muscle reaction time, rate of change in muscle amplitude and muscle amplitude between groups and conditions...

Recently, addition of a gymnastics glide kip to a standard pull-up (SPU) has resulted in the kipping pull-up (KPU). Changes in muscle activation and kinematics were evaluated with eleven athletes performing sets of 5 SPU and 5 KPU. Surface electromyography of upper body and lower body muscles was recorded along with movement kinematics obtained via markers and motion tracking software. Most kinematic variables were significantly higher in the KPU including (KPU minus SPU deg): Max hip angle (48.8° ± 6.8°, p < 0...

BACKGROUND: Facial edema is a common complication after neck dissection and/or chemoradiotherapy for head and neck cancer. Edema subsides spontaneously in most cases but sometimes persists, in which case surgical intervention is required. We report a case of severe facial edema that showed significant improvement upon lymphovenous anastomosis (LVA). METHODS: A 66-year-old man with oral floor cancer developed progressive facial lymphedema after tumor resection, bilateral neck dissections, chemoradiotherapy, and fibular and rectus abdominis musculocutaneous flap transfer...
