Summary

What Researchers Did

Researchers conducted a comparative non-randomised study to evaluate the short-term and long-term effects of hyperbaric oxygen therapy on 32 Japanese professional or semi-professional rugby players with grade 2 medial collateral ligament injuries.

What They Found

They found that visual analog scale (VAS) scores for pain while walking significantly decreased from 37.4 to 32.4 immediately after hyperbaric oxygen therapy (p<0.001). The abstract does not provide the results for the time to return to play, which was the intended long-term outcome.

Canadian Relevance

This study was conducted in Japan and has no direct Canadian connection.

Study Limitations

Key limitations include the non-randomised design and the abstract's incomplete reporting of the long-term outcomes, such as time to return to play.
