Do textbooks agree on their advice on ice?

OBJECTIVE

To study ice therapy guidance in sports medicine textbooks.

DATA SOURCES

A systematic search of a convenience sample of textbooks.

STUDY SELECTION

45 general sports medicine texts were included in the study.

DATA EXTRACTION

The indices and chapter headings of each text were searched using key words "ice," "cryotherapy," "soft tissue injury," "muscle," and "bruise."

DATA SYNTHESIS

In 17 of the textbooks, there was no guidance on the duration, frequency, or length of ice treatment or on the use of barriers between ice and the skin. Advice on treatment duration was given in 28 texts but recommendations differed depending on the particular ice therapy, injury location, or severity. There was considerable variation in the recommended duration and frequency of advised treatments.

CONCLUSION

There was little guidance in the standard textbooks on ice application, and the advice varied greatly. There is a need for evidence-based sport and exercise medicine with a consensus on the appropriate use of ice in acute soft tissue injury.
