An evaluation of rapid exchange and simultaneous grip tests.

The usefulness of the rapid exchange grip test and a modification of this test, the rapid simultaneous grip test, in detecting submaximal grip efforts was evaluated. Uninjured subjects giving maximal or submaximal grip efforts were tested at grip rates of 80 and 100 repetitions per minute. Rapid exchange grip at 80 repetitions per minute yielded a sensitivity of 86% and a specificity of 97%. Rapid simultaneous grip at 80 repetitions per minute yielded a sensitivity of 81% and a specificity of 93%. Poorer sensitivities and specificities resulted when a clinical population of patients was tested. Patients who were not giving maximal efforts tended not to comply with the test protocol. The rapid exchange and rapid simultaneous grip tests do assist in detecting submaximal grip efforts; limits to these tests are emphasized.

Persistent posttraumatic orbital-antral fistula.

The case of a symptomatic persistent orbital--antral fistula after silicone orbital floor reconstruction is presented. Intermittent diplopia with Valsalva maneuvers was the patient's chief complaint. Periorbital cellulitis was a suspected complication of the fistula. This case emphasizes the importance of an often overlooked goal of orbital floor reconstruction, that is, isolation of the orbital cavity from the maxillary sinus. Greater care in positioning alloplastic implants may improve their function. Autogenous materials may be superior in orbital floor reconstruction.
