The effect of Tai Chi Quan and computerized balance training on postural stability in older subjects. Atlanta FICSIT Group. Frailty and Injuries: Cooperative Studies on Intervention Techniques.

BACKGROUND AND PURPOSE: This study explored whether two exercise programs would affect the ability to minimize postural sway of 72 relatively inactive, older subjects who participated in the Atlanta FICSIT trial. SUBJECTS: Subjects were randomly assigned to (1) a computerized balance training group, (2) a tai chi group, or (3) an educational group serving as a control for exercise. Each group consisted of 24 members. METHODS: All subjects were evaluated under four postural conditions before, immediately after, and 4 months following their respective interventions, each of which was given over 15 weeks. RESULTS: Platform balance measures revealed greater stability after training among subjects in the balance training group but little change in stability among subjects in the tai chi and educational group. Subjects in the tai chi group were less afraid of falling after training compared with subjects in other groups with similar covariates. CONCLUSION AND DISCUSSION: Unlike computerized balance training, tai chi does not improve measures of postural stability. Because tai chi delayed onset to first or multiple falls in older individuals, this effect does not appear to be associated with measures of enhanced postural stability. Tai chi may gain its success, in part, from promoting confidence without reducing sway rather than primarily facilitating a reduction in sway-based measures.

Sampling in physical therapy research.

Although the importance of appropriate statistical analyses of the results of physical therapy research is well documented, the theory and methodology of sampling, the procedure by which the data of research are usually obtained, has received much less attention in the physical therapy literature. To help fill this gap, some of the basic concepts and techniques of sampling are discussed.

Beyond analysis of variance. A comparison of some multiple comparison procedures.

In analysis of variance, when the null hypothesis of no difference among several treatment means is rejected, the investigator concludes that not all treatment means are equal. The logical question that arises at this point concerns which means, then, are different from which others. In many research reports, this question is never answered. In those instances where an attempt is made to pinpoint just where the differences among means occur, the procedure employed is frequently inappropriate. This article describes the most frequently used of the theoretically sound procedures that are available for making all possible comparisons among means. Four procedures are illustrated with the same experimental example.
