STUDY DESIGN Retrospective study. PURPOSE To investigate the influence of fat infiltration at low back extensor muscles on osteoporotic vertebral fracture. OVERVIEW OF LITERATURE In persons with stronger back muscles, the risk of osteoporotic vertebral fractures will likely be lower than in those persons with weaker back muscles. However, the degree of influence of fat infiltration of the b...

Under normal circumstances, blood collected from superficial venous capillaries is directed upward and inward via one-way valves into superficial veins. These in turn drain via perforator veins, which pass through muscle fascia into deeper veins buried under the fascia. Leakage in a valve causes retrograde flow back into the vein. Unlike deep veins which are thick-walled and confined by fascia,...

The histochemical characteristics, cross-sectional area and capillary of the skeletal muscle fibers of the anterior and posterior regions of the superficial masseter and the temporalis muscles are described for juvenile and adult rhesus monkeys of both sexes. Slow twitch fatigue resistant (S), fast twitch fatigue resistant (FR) and fast twitch fatigable (FF) fibers were found in varying proport...

The author has derived the closed-form dynamic equations for a planar musculoskeletal chain composed of generic number n rigid links connected by ideal revolute joints. Single-joint and multi-joint muscles have been modeled as linear force actuators that can span from one joint to all joints chain. shape size each individual link accounts different alignments among center mass link, centers rot...

BACKGROUND Specific stabilizing exercises activating deep local muscles in coordination with global muscles are recommended in the treatment of pregnancy-related lumbopelvic pain. Some studies have suggested that recruitment of the deepest abdominal muscle, transversus abdominis, is crucial in the development and improvement of lumbopelvic pain. OBJECTIVE This exploratory study aimed to descr...

OBJECTIVE There is some evidence for the efficacy of acupuncture in chronic low back pain, but it remains unclear which acupuncture modes are most effective. Our objective was to evaluate the effects of two different modes of trigger point acupuncture on pain and quality of life in chronic low back pain patients compared to standard acupuncture treatment. METHODS Thirty five consecutive out-p...

OBJECTIVES This study evaluated the effects of facial stimulation over the superficial muscles of the face in individuals with facial lipoatrophy associated with human immunodeficiency virus (HIV) and with no indication for treatment with polymethyl methacrylate. METHOD The study sample comprised four adolescents of both genders ranging from 13 to 17 years in age. To participate in the study,...

This study examined the anatomical and functional relationships between the abductor pollicis longus (APL) and the abductor pollicis brevis (APB) muscles. The APL has 2 divisions, a distal superficial division and a more proximal deep one. A direct anatomical connection between the extrinsic and intrinsic muscles of the thumb is made up by the deep division of the APL, the APB and the trapezium...
