BACKGROUND: Upper limb repetitive strain injury is a common problem in western countries, causing human suffering and huge economical losses. Patients with prolonged pain associated with repetitive tasks in the work place can face both psychological and physical difficulties. Different treatment programmes, physical, psychological, behavioural, social and occupational treatments have been developed and used to help these patients.

Evolution of altruism by group selection involves sacrifice of some individuals, not to the "group as a whole," but to other individuals in the group. Deme-group selection may establish strictly altruistic genes in a population, but only under limited conditions, and perhaps never among vertebrates, among which apparently altruistic behaviors may always potentially benefit the altruists. Responsive-group selection is a more effective mode of evolution of altruism, conspicuous in man.

Step duration, measured in hemiparetic patients walking on a circular path, showed that step duration of the affected foot is usually longer. Functional electrical stimulation of the peroneal nerve in the swing phase of the step (eliminating foot drop) shortened step duration in the majority of cases.

Using 133Xe regional cerebral blood flow (CBF) imaging, two male groups having high and low hypnotic susceptibility were compared in waking and after hypnotic induction, while at rest and while experiencing ischemic pain to both arms under two conditions: attend to pain and suggested analgesia. Differences between low and highly-hypnotizable persons were observed during all hypnosis conditions: only highly-hypnotizable persons showed a significant increase in overall CBF, suggesting that hypnosis requires cognitive effort.

The study examined the effectiveness of behaviorally-induced vasodilation (hypnosis with biofeedback and autogenics) in the treatment of upper extremity repetitive strain injuries (RSI). Thirty patients with recent onset of upper extremity RSI symptoms were randomly assigned to 1 of 2 treatment conditions, i.e., hypnotically-induced vasodilation or a waiting-list control. Treatments were given on an individual basis, once a week for 6 weeks. Patients in the treatment condition showed highly significant increases in hand temperature between pre- and post-treatment.
