This study compared chronic and acute range of motion (ROM) changes of hip flexion and shoulder extension between men and women and a control group during a 12-week program. Comparative increases in flexibility in women were not significantly different from those in men. (JD)

Discusses techniques for studying large-scale brain activity, insights from computational modeling, and cognitive processes that could lead to a better understanding of cognition. Describes interactions between psychology and physiology in perception, structural levels of organization in the nervous system, techniques and research strategies. (RT)

The pain-control phase of a rehabilitation program may include flexion or extension exercises, lumbar mobilization, traction and selective injections. When the pain has been relieved, the patient advances to the training phase. (JD)

Changes in upper/lower lip integrated electromyographic (IEMG) amplitude and temporal measures related to linguistic factors known for their influence on stuttering were investigated in 12 male Dutch nonstutterers. Findings indicated that production of stressed, vowel-rounding gestures of words in initial position, longer words, and words in…

Develops a research-oriented method of studying the digestive system that integrates species' ecology with the form and function of this system. Uses problem-posing, problem-probing, and peer persuasion. Presents information for mammalian systems. (27 references) (MKR)

This article focuses on definitions of middle ear inflammation (otitis media), the epidemiology of this disorder, brief considerations of pathophysiology and management, and possible future therapies. (DB))

Uses a behavior model from control systems theory to analyze how we coordinate our own and each other's physical movements. Tests one person controlling a cursor with one handle or two, and two people controlling a cursor with two handles. Shows that control theory accurately predicts the results. (CH)

Long-term effects on auditory electrophysiology from early fluctuating hearing loss were studied in 27 children, aged 5 to 7 years, who had been evaluated originally in infancy. Findings suggested that early fluctuating hearing loss disrupts later auditory brain stem electrophysiology. (Author/DB)

This study of single-joint elbow flexion movements by 10 subjects with Down's syndrome (ages 14-19) and 6 control subjects concluded that there are no major qualitative deficits in the motor control mechanisms of individuals with Down's syndrome, but there might be problems with proper modulation of motor commands. (Author/JDD)

The body of data indicating sex differences in the brains of almost every mammalian family examined so far (rodents, birds, monkeys, and human beings) is reviewed. The differences in the hypothalamus, thalamus, corpus callosum, anterior commissure, and the hippocampus are described. (KR)

Study compared cardiac structure and function in adult male weight trainers, runners, and those who did both. Results indicate men who run or weight train and run have similar heart structural and functional characteristics and greater relative internal diameter and left ventricular wall thickness than men who only weight train. (SM)

The clinical characteristics of cocaine addiction, cocaine abstinence symptoms, and the short-term and long-term neurochemical actions of cocaine are discussed. The relative therapeutic value of various medications and treatment programs are discussed. (KR)

Research indicates the process of menstruation has no effect on female college students' academic performance when measured by quantitative tests, and it appears subjective complaints of paramenstrual dysfunction originate in socially mediated beliefs and expectations. Implications for academic assessment, student counseling, employment policy,…

Because many experts recommend stretching after exercise to relieve muscle soreness, 23 subjects performed a 30-minute step test to induce delayed muscle soreness. There was neither temporary relief of pain immediately after stretching nor a reduction in pain during the 3-day postexercise period. (Author/SM)

Astronauts on lengthy spaceflights must exercise regularly to forestall muscle atrophy and bone loss, but exercise presents unique problems in a weightless environment. All exercise equipment must have a harness or seat belt. Soviet and NASA space exercise plans and experimental ideas are discussed. (Author/SM)
