Abstract

In this study, a 4-item battery of core stability (CS) tests modeled on core stabilization activities used in training and rehabilitation research was developed, and a measurement schedule was established to maximize internal consistency and stability reliabilities. Specifically, we found that 4 test administrations on each of 4 days produced intraclass correlation coefficients that in most instances exceeded 0.90 and stability reliability coefficients on the third and fourth days of testing that exceeded 0.90 for 2 of the tests and 0.80 for the other 2. Thus, it is recommended that in future research, examiners administer the battery for at least 3 days and consider the data collected on day 3 as the best estimate of participant CS.

Femoral nerve entrapment: a new insight.

Compression of the femoral nerve in the iliac fossa has been reported as a consequence of several pathologies, but never as a result of muscular compression. Aberrant slips of iliacus, however, have occasionally been reported to cover or split the femoral nerve. This study aimed to assess such variations as potential factors in femoral nerve compression. A large and homogeneous sample of 121 embalmed cadavers (242 specimens) was studied. Statistical comparisons were made using the chi-squared test. Muscular slips from iliacus and psoas, piercing or covering the femoral nerve, were found in 19 specimens (7.9%). No significant differences by sex or side were found. The more frequent variation was piercing of the femoral nerve by a muscular slip (17 specimens, 7.0%). The nerve then entered the thigh as one or more branches. The less frequent variation found was a muscular slip or sheet covering the femoral nerve as it lay on iliacus (2 specimens, 0.8%). Each disposition may be a potential risk for nerve entrapment.

Measurement of tension-free vaginal tape trocar insertion and exit forces.

BACKGROUND/AIMS: This study aims to establish a model to measure the forces required for tension-free vaginal tape (TVT) trocar application using a pressure transducer. METHODS: A 3.5 x 3.5 cm pressure transducer was constructed from piezo-resistive material. The transducer digitally recorded the surface contact pressure (pressure = force/area) profile continuously during TVT trocar application. Recordings were successfully obtained from 24 subjects. RESULTS: The mean (standard error) peak contact pressures during application at the right and left side vaginal walls, and right and left side abdominal walls were 1.05 (0.12) pounds per square inch (psi), 1.08 (0.21) psi, 2.49 (0.3) psi and 2.49 (0.3) psi, respectively. On both the right and left side, pair-wise comparisons between trocar insertion and exit forces were significantly different (p < 0.001). CONCLUSION: A model has been developed by which TVT trocar application forces can be objectively measured. The TVT trocar exit force is substantially greater than the insertion force, regardless of side.
