Innovations in hearing loss detection &...( ntence materials (VA Sentence Test--VAS...),Health

ntence materials (VA Sentence Test--VAST) was developed using principles of the Neighborhood Activation Model (word-usage frequency and word confusability). Each sentence had three target words that were used as the measure in an adaptive threshold technique. Ten listeners with varying degrees of hearing sensitivity participated in five test sessions over 5 to 10 days. Data indicated word-recognition performance improves with repeated exposure to the test paradigm across several days of exposure. Improved performance across test sessions was not appreciably affected by age and degree of hearing loss.

Resistance exercises improve muscle coordination and strength in elders, pg 253
Eighty-nine elders with limited physical functioning participated in a study to evaluate if resistance training improved coordination and muscular strength. Study volunteers were place into one of two groups: either a no-treatment control or a 6-month in-home video-facilitated elastic-band resistance exercise program. The intervention group improved knee extension strength by 17 percent and hip extension by 21 percent and improved coordination and timing between peak knee and hip extension powers during lifting. Resistance-trained elders with a physical disability demonstrated strength benefits and improved coordination and more efficient lifting. More leg muscle power yields better functional lifting performance.

Cadaveric model aids in evaluating surgery techniques to repair shoulder dislocation, pg 265
Article discusses the development of a novel cadaveric shoulder dislocation model that yields in vivo pathology, structural and functional changes within the body. Using a custom testing device that simulated shoulder muscle forces, cadaveric shoulders were dislocated. Forcible positioning using this shoulder dislocation model yielded inflammation and tearing of the shoulder and stretching similar to lesions observed in vivo. Shoulder instability i
