Effects of structured relaxation on retrieval from long term storage: an EMG study.

The effects of 20 min structured relaxation immediately prior to retrieval were observed for word lists learned 48 hours previously. Error probabilities and response latencies were scored at acquisition and retrieval for paired associates at two levels of response dominance. Frontalis isometric muscles tension was measured just prior to and during retrieval. Relaxation markedly reduced EMG activity associated with muscle tension. This effect did not extend to the retrieval period. Error probabilities were significantly lower for retrieval preceded by relaxation but the interaction between relaxation and response dominance proved non-significant. These findings suggest that states of low arousal do not bias memory search to readily accessible information as appears to be the case for high arousal.

Femoral neuropathy after renal transplantation.

We report nine cases of neuropathy occurring after renal transplantation, seven of them femoral and two lateral femoral cutaneous. The average time of onset of symptoms is 2.2 days after surgery. Quadriceps weakness, hypoesthesia, and abnormal results of EMG and nerve conduction studies are common and occur on the same side as the operation. The symptoms usually resolve within weeks, but motor and sensory changes can persist. The lesion is thought to be secondary to compression caused by a hematoma at the operative site.

The 1977 Busselton children's survey.

A health survey of 551 high school students in the coastal town of Busselton, Western Australia, was undertaken in November, 1977. Physical measurements showed that approximately 17% of the boys and 24% of the girls were overweight (115% or more of their standard weight for height and age). Blood pressures ranged from 108/64 mmHg at 13 years to 129/70 mmHg at 17 years for boys, and 109/63 mmHg to 116/66 mmHg for girls of the same age group. Fasting plasma glucose, cholesterol and triglyceride values were also obtained. Twenty-seven per cent of the girls and 17% of the boys were regular smokers, a habit often acquired by the age of 12 years. Most of the children watched television from two to four hours daily during the week, and for longer periods at weekends. Although most had satisfactory levels of physical fitness, there was a trend towards poor performance in overweight children, and there was a significant decrease in participation in regular sports by the older teenagers.
