A report was made of tests on the voluntary strengths of 15 male adults with acute low back syndromes by use of a strength testing program. The feet of each subject were placed in prescribed positions relative to an instrumented workpiece, which measured the hand forces exerted in a series of tasks. Subjects exerted forces on the workpiece in six different directions. The major findings were: acute back syndrome patients have considerable physical ability in many of the situations examined, often fully comparable to that of healthy subjects; generally, either patients were unable even to assume a given position, or else their performances were close to normal in all exercises in each position; and the positions which a significant number of patients could not assume were those involving substantial trunk twisting, or combinations of bending and twisting.
