Generalized eruptive histiocytosis is a benign proliferative disorder of non-Langerhans cells. It is a very rare disease. The disease presents with soft to firm fleshy papules on face, neck and upper trunk. Biopsy is often needed to make the diagnosis because of its rarity and diverse presentation. There is tendency for the disease to regress spontaneously without treatment. Treatment, if any n...

The purpose of this study was to investigate the effect of the racket mass and the rate of strokes on the kinematics and kinetics of the trunk and the racket arm in the table tennis topspin backhand. Eight male Division I collegiate table tennis players hit topspin backhands against topspin balls projected at 75 balls · min(-1) and 35 balls · min(-1) using three rackets varying in mass of 153.5...

[Purpose] This study investigated the effects of gait time and trunk acceleration ratio in old-old adult females during stair climbing. [Subjects and Methods] Twenty-five older adult females who were able to walk independently volunteered for this study and were categorized into two age groups (older adults or old-old adults). Gait time and trunk acceleration ratio were measured using an accele...

This study investigated the validity of the top-down approach of inverse dynamics analysis in fast and large rotational movements of the trunk about three orthogonal axes of the pelvis for nine male collegiate students. The maximum angles of the upper trunk relative to the pelvis were approximately 47°, 49°, 32°, and 55° for lateral bending, flexion, extension, and axial rotation, respectively,...

It has been hypothesized that cutaneous melanoma at different anatomic sites develops through divergent pathways. We examined this hypothesis prospectively. We followed 152,949 women and 25,204 men free of cancer at baseline for up to 14 years in three large prospective studies. We examined risk factors for melanoma by anatomic location (head or neck, trunk, upper extremity, and lower extremity...

Abstract Introduction: Low back pain(LBP) affects many individuals and is known to be associated with impaired trunk control. While LBP can by treating underlying impairments, a better understandinf of the mechanistic origin disorder required. Trunk control has been commonly studied via an unstable sitting paradigm. Knowledge on how base support body segments work together complete task, this m...

Title of Document: POSTURAL COORDINATION PATTERNS: VISUAL ROTATION AND TRANSLATION Yuanfen Zhang, MA, 2006 Directed By: Professor John Jeka, Department of Kinesiology Recent studies have shown co-existing trunk-leg coordination patterns during quiet stance: in-phase and anti-phase for frequencies below and above 1 Hz, respectively. Two experiments investigated whether the nervous system assumes...

The aim of this study was to determine cognitive and motor status factors in female and male children aged 10-14, as well as developmental and/or integration functions according to gender. The study included 162 girls and 134 boys aged 10-14, divided into four groups: 84 girls aged 10-12 (mean age 11.26, SD 0.68), 84 boys aged 10-12 (mean age 11.41, SD 0.50), 78 girls aged 13-14 (mean age 13.52...

background and objective: neurofibromas occur as solitary and multiple forms. the solitary ones are extraneural and more common, histologically exhibiting spindle cells with wavy nuclei, scattered among collagen fibers. multiple neurofibromas are seen in neurofibromatosis (types i and ii), including intraneural (plexiform, cutaneous deep circumscribed) and extraneural (cutaneous, deep diffuse) ...

Individual body segment actions evolve during throwing skill development. Maximal trunk involvement is typically the last feature of the movement pattern to fully develop. The current study examined developmental levels of trunk action and the associated variability in the throwing motion. The throwing motions of children and adolescents were analyzed via motion capture and trunk actions were c...
