Supernumerary ectopic limb(s) (SEL) is a congenital anomaly defined as the presence of accessory limb(s) attached to various body regions. This paper describes a case of SEL with ectopic lung and ectopia cordis in a newborn calf, based on macroscopic, microscopic and radiographic findings. External features of multiple congenital anomalies included an ectopic lung growing over the middle of the backbone and covered with normal haired skin. Ectopia cordis was found in the abdominal cavity and attached to the liver. Two extra abnormal limbs originated separately from within the ectopic lung. Most of the abdominal organs were exposed to the outside through the opened abdominal cavity. Microscopically the ectopic lung tissue had edema in the connective tissue around the bronchus and artery. Changes in other organs included congestion of the renal medulla, infiltration of inflammatory cells (lymphocytes and eosinophils) around the hepatic portal tract, and edema surrounding blood vessels and neurons in the brain. The rudimentary humerus of the forelimb was attached to the thoracic spine, as viewed radiographically. The hindlimb was consisted of an irregularly shaped femur, short tibia and fibula, two tarsal bones, one metatarsal bone, and three phalanges. This is the first description of congenital anomalies involving the SEL, ectopic lung and ectopia cordis in a calf.

Background: Neurodynamic mobilization is divided into slider mobilization and tensioner mobilization. However, movement direction in neurodynamic mobilization has been overlooked in neurodynamic exercise program. Objective: To examine the effect of movement direction in neurodynamic mobilization on upper limb mobility and pain. Design: Quasi-experimental study Methods: Twenty-two adults positive for neurodynamic test for the median nerve were recruited for participation in this study. Twenty-two subjects were allocated to the applied neurodynamic mobilization at limited side group (ANTLS, n=7), the applied neurodynamic mobilization at contralateral limited side group (ANTCLS, n=7), and the applied neurodynamic mobilization at bilateral side group (ANTBS, n=8). Before the intervention upper limb limited was measured neurodynamic test for the median nerve, pain was measured using visual analogue scale (VAS), movement direction in neurodynamic mobilization was applied to each group, and then re-measured using neurodynamic test for the median nerve and VAS. Differences the Intra-groups before and between the intergroups after intervention were analyzed. Results: In the ANTLS and ANTBS groups, a statistically significant increase in ROM and decrease in VAS score in the population before and after intervention were indicated. Statistically significant differences in VAS and ROM from before to after intervention were found among the ANTLS, ANTCLS, and ANTBS groups. Conclusions: The results of the present study indicate that movement direction in neurodynamic mobilization must be considered within the limits of its selected range of the neurodynamic exercise program.

Purpose: The aim of the study was to investigate neck posture, range of motion, muscle endurance and self-report of pain and disability in smartphone users. Methods: Seventy-eight university student volunteers, aged between 18 and 30 years (mean age 23.2), were assessed for: a head-neck posture by measuring cranial vertical angle, neck range of motions using cervical range of motion device, and a deep neck flexor endurance using a stabilizer. Finally, subjects were asked about their neck pain and completed disability questionnaires, ie, Short Form McGill Pain Questionnaire, Neck Disability Index, and World Health Organization Disability Assessment Schedule 2.0. Results: Thirty-eight subjects experienced recurrent neck pain with/without upper limb pain (neck pain group) and 40 reported no current neck pain with/without upper limb pain (no neck pain group). Differences were found between groups on pain and disability questionnaires. Subjects with neck pain had significantly higher disability scores than those of no neck pain group. However, there were no differences observed between groups in a head-neck posture, neck range of motions, and deep neck muscle endurance time. The smartphone usage time was negatively correlated with neck pain intensity and disability score whereas it had positive relationship with flexibility and posture. Conclusion: Group differences were observed as lower capacity not only for neck specific daily activities but for general functioning in daily routine when the neck pain and no neck pain groups were compared. Therefore, functioning in daily activities should be investigated as prevention for further developing neck pain in smartphone users.

PURPOSE: This study was conducted to identify the effects of altering foot position on quadriceps femoris including vastus medialis obliques (VMO), vastus lateralis (VL) and rectus femoris (RF) activation during wall squat exercises. METHODS: All subjects (n = 15) were selected and randomly performed three kinds of wall squats: 1) GWS (General Wall Squat), 2) WSS1/4 (Wall Squat Short 1/4), and 3) WSS1/2 (Wall Squat Short 1/2). Each subject completed all three kinds of wall squatting exercises at three different times and recorded the muscle activity data of vastus medialis obliques, vastus lateralis and rectus femoris. RESULTS: Compared with GWS exercise, VMO and RF muscle activity significantly increased under WSS1/2 exercise (p < .05), while only RF muscle activity significantly increased under WSS1/4 exercise (p < .05). CONCLUSION: The results of the present study indicate that moving the foot toward the wall during wall squats has a positive effect on quadriceps activation. The exercise of wall squat short can not only be used as the lower limb muscle strengthening training for normal people, but also as the recovery training for patellofemoral pain syndrome patients in the rehabilitation stage. Besides, Anterior cruciate ligament patients can also try this exercise according to the advice of doctors and therapists.

The purpose of this study os to investigative the effect of Carrageenan-Induced Pain on lower limb muscle and ligament of rat. To evaluate pain mechanism in muscle and ligament, pain was induced by the injection of 2% $0.1m{\ell}$ carrageenan into the left lower limb muscle of rats after rats were anesthesized with 3% enflurane. Rats were killed on 72 hours after pain induction under the anesthesia. anterior rectus femoris muscle and its ligament were removed from rat hind limb. Morphological changes of them were peformed by the observation of light and electron microscopes. In the light microscopic findings, the muscle cells were polyheadral and situated with each other without small gap in control group. nucleus of cell was seen along the cell margin, and muscle cell groups were divided by regular narrow gap in cross section. In the pain-induced group, muscle cell groups were divided each other by the irregular gap, and some of groups formed larger than other cell groups by the fusion. Intercellular gap of most cell groups were increased compared with control groups. And also, perimysium of muscle cell groups was swollen in cross section. In control group, muscle cells contacted each other closely and each cell was divided by perimysium. The intracellular gaps were not seen between myofibrills, and also striations were well defined between muscle cells in longitudinal section. In pain-induced group, muscle cells were divided by the small intracellular gaps. And also, muscle cell showed many a short cross or longitudinal intercellular gaps in longitudinal section. In light microscopic findings of control group, tendon was composed with many tendon fibers contacted each other closely without gap. The free margin of tendon was fused, and apso the tendon fibers did not invaded between muscles. In pain-induced group, tendon was divided small groups by intertendinous gap, and also the margin of tendon divided by small groups. In the free margin, tendon invaded into muscle cells, and also fibroblasts between tendon fibers were long and lance-shaped. From these results, it is suggested that pain induction by carrageenan injured rat skeletal muscle and ligament by the morphological changes.

Objectives: This study presented the case of a 49-year-old Korean female with phantom limb pain after below right knee amputation and aimed to assess the effectiveness of Korean medicine treatment. Methods: The patient was treated with scalp acupuncture, electroacupuncture and herbal medicine. We executed a numerical rating scale (NRS), conducted a global assessment (G/A), administrated a Short-Form McGill Pain Questionnaire 2 (SF-MPQ-2) and measured total daily sleep time to evaluate symptom improvement. Results: The patient's G/A scores decreased from 10 to 2 and SF-MPQ-2 points decreased from 20 to 6 after treatment. The total daily sleep time did not changed due to anxiety. Conclusions: This study suggests that Korean medicine treatment could be effective in treating phantom limb pain after amputation. Further studies are needed.

Three dogs were admitted for repair of bone fracture. Case 1 (Maltese, 1.8 kg, intact female, 5-month-old) and case 2 (poodle, 3.0 kg, intact female, 6-month-old) had non-weight bearing lameness in the left pelvic limb, and case 3 (mixed, 3.3 kg, intact female, age unknown) had non-weight-bearing lameness in the left thoracic limb. On orthopedic examination, there was pain, crepitus, palpable instability and substantial soft tissue swelling on the affected side. No neurological deficits were identified. Radiographs revealed left proximal metaphyseal tibial and fibular fractures in cases 1 and 2, and left proximal metaphyseal radial and ulnar fractures in case 3. All cases had closed long-bone fractures with short juxta-articular fracture segments. Under fluoroscopic guidance, proper placement of the ring fixation elements was confirmed during surgery. Two or three rings were used to stabilize fractures with traditional circular external skeletal fixators (CESF). Postoperative radiographs showed acceptable alignment and apposition of the previously identified fracture. Time to radiographic union ranged from 5 to 14 weeks and there were no signs of implant failure or pin tract infection. Functional outcomes were excellent in all cases. CESF can be successfully used to reduce short juxta-articular fractures in which bone plates or external skeletal fixation cannot be applied.

As technology advances, there is increasing need for research in different fields where this technology is applied. On of the most researched topic in computer vision is Human activity recognition (HAR), which has widely been implemented in various fields which include healthcare, video surveillance and education. We therefore present in this paper a human activity recognition system based on scale and rotation while employing the Kinect depth sensors to obtain the human skeleton joints. In contrast to previous approaches that use joint angles, in this paper we propose that each limb has an angle with the X, Y, Z axes which we employ as feature vectors. The use of the joint angles makes our system scale invariant. We further calculate the body relative direction in the egocentric coordinates in order to provide the rotation invariance. For the system parameters, we employ 8 limbs with their corresponding angles each having the X, Y, Z axes from the coordinate system as feature vectors. The extracted features are finally trained and tested with the Long short term memory (LSTM) Network which gives us an average accuracy of 98.3%.

To consider the iliac fossa as the vascular anastomosis site of kidney transplantation for the short-term study of acute rejection in pigs. Twelve domestic pigs weighing 39~48 kg underwent heterotopic renal allgraft transplantation. The experimental animals were divided into 2 groups in terms of renal vascular anastomosis site; the external iliac artery and vein were used in iliac fossa model (n = 6), the abdominal aorta and the caudal vena cava inferior to the kidney were used in abdominal cavity model (n = 6). Renal function was evaluated by daily measurement of plasma creatinine and BUN concentrations. The experiments' health including postoperative complications was also assessed daily for 8 days after transplantation. After euthanazation gross and histopathologic analysis was performed. All six pigs in iliac fossa model developed neuropraxia and lameness of the ipsilateral pelvic limb. However, no necrosis was observed in any pigs. In the abdominal cavity model, durations of both the surgical operation and the vascular anastomosis were significantly longer than those in the iliac fossa model. Furthermore, ischemia injury of the transplanted kidney was increased in abdominal cavity model, which induced accelerated-acute immune response from day 4 after transplantation. Despite of pelvic limb complication, the iliac fossa model showed more advantages including not only less ischemia time related to easy vascular anastomosis, but also less immune response during the acute rejection period. The results indicate that the iliac fossa model may be appropriate to the study of acute rejection in porcine kidney transplantation.
