[Purpose] The purpose of this study was to elucidate whether skin extensibility decreases when a contracture develops as a result of joint immobilization. [Subjects] This study was conducted on six female Wistar rats. [Methods] The rats were divided into two experimental groups. In the immobilized group, the right ankle joints were immobilized in complete plantar flexion by plaster casts for two weeks. In the control group, the left ankle joints had no intervention. On the final day, skin extensibility was determined from a length-tension curve by collecting skin from the posterior aspect of the ankle joint and using a tensile strength tester. [Results] Compared with the control group, the immobilized group showed a significant decrease in skin extensibility. [Conclusion] The results demonstrated that the extensibility of the skin itself decreases when joint contracture develops.

Bilateral Preseptal Cellulitis and Upper Eyelid Abscess Without Predisposing Factors: A Case Report and Pathogenic Hypothesis.

Bilateral preseptal cellulitis without accompanying sinusitis or skin trauma is uncommon. In this report, we present a case of bilateral preseptal cellulitis and an upper eyelid abscess in an otherwise healthy child. A nine-year-old girl presented with severe and progressive bilateral swelling of the upper lids that showed an unsatisfactory response to medical treatments (intravenous ceftazidime and vancomycin) and warranted a referral to our facility.

Spine kinematics are commonly measured by external sensors such as motion capture and accelerometers. However, these skin-based measures cannot directly capture intervertebral motion of the lumbar spine. To date, research in this area has focused on the estimation of intervertebral kinematics using static trials but no study has analyzed agreement throughout the dynamic range of motion.

Pathological tremors can often be debilitating to activities of daily living and significantly affect the quality of life. Such tremulous movements are commonly observed in wrist flexion-extension (FE). To suppress this tremor we present a wearable robot (WR) with a customized mechanical metamaterial (MM) as the physical human-robot interface (pHRI).
