Summary

What Researchers Did

Researchers measured intentional tremor in six subjects during a U.S. Navy experimental chamber dive to 49.5 ATA, obtaining objective measures at various depths using a specialized tremor device.

What They Found

All six subjects showed a marked increase in tremor, interfering with fine motor performance at depths greater than 1000 fsw (31.3 ATA). A statistically significant increase in signal frequency was also observed.

Canadian Relevance

This study has no direct Canadian connection.

Study Limitations

The study's findings are limited by its small sample size of six subjects and its focus on a highly specific experimental chamber dive environment.
