This study investigated the use of the long sitting test as an indicator of iliosacral dysfunction. Fifty-one subjects between the ages of 18 and 37 were assigned to either an experimental group or control group through a screening procedure. The 30 subjects in the control group had even posterior superior iliac spine (PSIS) heights and negative standing and sitting flexion tests. The 2 1 subjects in the experimental group had uneven PSIS heights, positive standing flexion tests, and negative sitting flexion tests. Measurements were taken of the change in the subjects' malleoli as they moved from a supine to a sitting position. Additional suppkmental and confirmational tests were then administered. The results of the long sitting test for iliosacral dysfunction were found to be significant at the 0.01 level. Possible influences on this test indicated by the confirmational and supplemental tests were also explored.

This research project was undertaken as a component of a comprehensive assessment of the University of Connecticut's freshman football team. The purpose of this study was to identify weaknesses in the neck musculature and note any relationships between strength differences and cervical spine stability. Neck muscle strength was evaluated using isometric contractions for the motions of flexion, extension, and right and left lateral flexion. Statistical correlations were derived for each of the 28 male subjects, who were divided into two groups of 14 linemen and 14 runningbacks. A Human Performance Regulator, which electrically evaluates neuromuscular force produced during an isometric contraction, was used to measure the force applied. A typical weightlifting power rack was used as a stabilization platform. The data recorded indicates that there are significant differences between the neck muscle strength of the two groups, as well as differences in neck muscle strength of individuals between their right and left sides. Looking at these muscular differences and their relationship to cervical vertebrae alignment during lateral flexion, the authors contend that blocking or tackling with the head in a laterally flexed position, to supposedly hit with the shoulder, places the cervical spine in a structurally weak position lacking muscular support, and predisposes the athlete to cervical spine injuries.

Twenty-one cases of transchondral fractures of the ankle, seen between 1980 and 1984, were studied. Twenty were available for follow-up. The average follow-up period was 23.5 months. In all cases but one the diagnosis was delayed. The diagnosis stated by clinical signs in medial transchondral fractures seems to be pathognomic: localized tenderness on the posterior medial side of the talus, pain increasing on exertion, and provocation of pain on passive plantar flexion.
