Post-Polio Syndrome as a Model for Musculo-Tendinous Overuse Syndromes in Military and Civilian Populations.
Abstract
Musculoskeletal injuries are common among military recruits: incidence rates of 20-90% have been reported. Of these, as many as 87% are due to overuse. The objective of this project was to predict individual's susceptibility to muscle overuse injury based on their pattern of weakness and to develop ways of preventing and treating these overuse injuries. The hypothesis is that focal weakness predisposes to overuse syndromes related to the weakened muscles and/or those used in compensatory movement strategies. The muscle weakness experienced by many polio survivors results in a pattern of accelerated overuse. This puts this population in a unique position to serve as an accelerated model for the same weakness-overuse-injury cycle experienced by military recruits and occupational athletes. Muscle strength, range of motion, and symptomatology data have been collected on 194 polio survivors and 226 able-bodied subjects. Among polio survivors, overuse symptoms were most common in the wrist, shoulder, knee and foot. There was a decrease in the mean strength of several muscle groups among polio survivors over a 6-9 month period. Several models were developed to define the relationship between specific areas of muscle weakness and overuse symptoms. In many cases, early results support the a priori predictions.
