Proximal wrist extensor tendinopathy

Proximal wrist extensor tendinopathy, which is also known as tennis elbow, is pain at or just distal to the lateral humeral epicondyle within the proximal wrist extensor tendon. It occurs commonly in certain athletes but can also occur in people with jobs that require repetitive movements of the hand and upper limb. In most cases the tendon involved shows no signs of inflammation or tendonitis, but instead shows fibroblasts, vascular hyperplasia, and disorganized collagen. Diagnosis is often made by history and physical exam alone. Most people respond to conservative measures including activity modification, analgesics, manipulation of tissue, and exercise. In some cases, an injection of corticosteroid or botulinum toxin may be used. Surgery is rarely needed

The conundrum of exercise for older men in TR settings

The purposes of this study were to determine how older men distinguished exercise from being physically active and to identify motives for exercising. Subjects were interviewed using a prepared script. They were encouraged to talk about how they characterized their exercise and physical activity (PA). Several themes emerged after transcripts were reviewed, including a tendency for men to engage in PA and exercise alone, a clear distinction between exercise and PA, and the primacy of psychological and mental benefits as motives for exercise. Comparisons were drawn between the male subjects in the present study and qualitative studies using older women as subjects, with some interesting gender contrasts apparent. The article ends with implications for practitioners.</jats:p

Growth properties and critical current measurements of Sm1+xBa2-xCu3O7-delta films on biaxially textured Ni tapes

The growth properties and field dependent critical current densities of Sm1+xBa2-xCu3O7-delta (SBCO) films on biaxially textured Ni tapes with CeO2/YSZ/CeO2 buffer layers were investigated. The window of substrate temperature (T-s) for c-axis normal growth in 5 mTorr of oxygen pressure were wider than 150 degreesC. The upper limit of T-s-window was much higher than that of Y1Ba2Cu3O7-delta (YBCO) films. Around the lower limit of T-s, SBCO films grew in [103] normal textures. The zero field critical currents (J(c)) were similar to6 times smaller than those of YBCO films, while the estimated pinning energies were less dependent on external fields than that of YBCO.
