Practice schedule and acquisition, retention, and transfer of a throwing task in 6-yr.-old children.

Earlier studies have raised questions about the usefulness of variable and random practice in learning motor tasks so this study was designed to investigate the effects of contextual interference in young children, and specifically to evaluate the effectiveness of variable or random practice structure in 6-yr.-old boys and girls. Participants on a variable practice schedule showed better performances than those on a blocked schedule. The differences between the two groups were significant in the acquisition, retention, and transfer phases. These results support the hypothesis that contextual interference enhances skill learning. Because the study involved groups of young children in the setting of their normally scheduled physical education class, the practical applications of the results are evident.

Rehabilitation of the elbow in the throwing athlete.

Rehabilitation following an injury to the elbow joint complex is common in physical therapy practice. The unique anatomical considerations of the elbow joint provide a significant challenge to the therapist in rehabilitating elbow injuries. The purpose of this paper is to describe the rehabilitation process for various elbow pathologies and provide a rationale for their treatment. The rehabilitation process for the injured elbow presented in this paper will emphasize phases that are progressive, sequential, and based on clinical and scientific research.

Denying behavior: throwing experience out.

A recent paper (Skarda, 1986) from a distinguished laboratory of experimental neurophysiology denies the classical concept of neural representation. According to this essay, which is itself a critique of a basic neuroscientific assumption as implied in a new book about the mind-brain problem, it is wrong to suppose that patterns of neural activity represent anything. Representations should be replaced by "self-organizing neural processes that achieve a certain end-state of interaction between the organism and its environment in a flexible and adaptive manner." Although this alternative wording is neither surprising nor radical, and would prove acceptable to most biologists as an adequate description of one important aspect of organized cellular activity, its author's dogmatic denial of "representation" as a metaphor for other important aspects of living behavior seems both surprising and unnecessary.

Reconsidering hepatorenal syndrome. Throw in the towel? Not so fast!

For many years, hepatorenal syndrome was considered a uniformly and rapidly fatal complication of end-stage liver disease. Although the syndrome still carries a poor long-term prognosis, increased understanding of its hemodynamic derangements has led to new pharmacologic treatments that significantly improve short-term outcomes. In this article, Drs Tong, Hurley, and Hayashi discuss a case of remarkable reversal of hepatorenal syndrome with use of oral midodrine hydrochloride, subcutaneous octreotide acetate, and intravenous albumin. The authors highlight the great progress that has been made in this field and review new therapeutic options that are on the market or under study. It is important for physicians who are caring for patients with hepatorenal syndrome to know about and consider the available treatments before an approach of "supportive care only" is taken.
