Of 214 croquet players who responded to a questionnaire, 76 reported a
t least one injury to hand, wrist or forearm caused by striking the ba
ll. There was no obvious relation to which of the three main grips the
player applied to the mallet. Injuries were somewhat more frequent wh
en the mallet shaft consisted of fibreglass than when it was wood, met
al or carbon fibre, but a causal relation has not been established. Ba
ck injuries seem less troublesome in croquet than in golf.
