OBJECTIVE. We assessed the prevalence of fear of falling (FoF) in a sample of people with chronic stroke and compared multiple variables (balance, anxiety, depression, activity and participation, and stroke severity) in people with and without FoF. METHOD. This study was a secondary analysis of data collected from a cross-sectional study of mobility after stroke in 77 participants with chronic stroke (>6 mo poststroke). RESULTS. Of the 77 participants, 51 (66%) reported experiencing FoF. People with FoF had significantly decreased balance (p< .001) and activity and participation (p = .006) and significantly increased anxiety (p = .007). People with FoF also had significantly worse stroke severity (p = .001). CONCLUSION. FoF is a prevalent concern in the chronic stroke population. The presence of FoF was associated with a variety of negative consequences. Occupational therapy practitioners should address FoF to help clients manage FoF and possibly improve recovery.

In 1991, five different total joint replacement surgeons performed 337 primary total knee replacements and 250 primary total hip replacements. They revised 25 total knee replacements and 73 total hip replacements. The average length of stay was 6.6 days for the primary total knee arthroplasty and 7.5 days for knee revisions. For total hip replacement, average stay was 5.9 days for primary surgery and 6 days for revisions. The operative time required for each of the five surgeons to complete a total knee replacement increased 55%, 3%, 38%, 72% and 38%; whereas for the total hip replacement, time increased 87%, 77%, 84% and 58%. Overall, there was a 41% increase in operating time for revision total knee replacements and a 77% increase for revision total hip replacement. Allowable charges by Medicare in 1993 for a primary knee and hip replacement were $1,298 and $1,363, respectively. Revision total knee replacement increased 24.3% ($1,613) and revision total hip replacement increased 30.8% ($1,782) in the state of Indiana. These figures do not encourage those surgeons who are capable of doing total joint replacements to revise other surgeons' problems.

A prospective study was done on Indiana University freshman football players to determine if the incidence of lumbar spondylolysis and spondylolisthesis followed the pattern of previous studies. Using x-ray film evaluation, 145 freshman players were followed through their careers from 1978 to 1983. As in previous studies, a higher percentage (15.2%) of the defect was found than exists in the general population. However, only 2.4% of these players developed the problem in college, a much lower figure than previously found. Affected team members played a variety of positions. In addition to spondylolysis, some other problems, such as spina bifida occulta, were found. Theories on the cause of spondylolysis and spondylolisthesis are reviewed, and preventive suggestions such as more careful training and weight lifting are presented.

Two hundred and eight skin knives and 374 deep knives were evaluated in 153 clean orthopedic cases with and without a horizontal wall-less laminar air-flow system. There was no statistical difference in contamination frequency between the skin and the deep knives with and without the laminar air-flow. However, the knife blades were found to be contaminated less than laminar air-flow was used than when it was not (P less than 0.005). No correlation could be made between the cultures of the wound edges and the depth of the wound with the contaminated knife blades.
