Ambulant and wheelchair bowlers with restricted grip and upper body limb function, poor balance and co-ordination, unable to bowl a full length end or needing a splinting device to do so (Not including the bowling arm as used in Australia). Bowlers with no arms who bowl with their feet.
B6: Ambulant and wheelchair bowlers with reduced balance function (loss of 5 points or more) but able to bowl a full length end.
B7: Ambulant and wheelchair bowlers with minor balance problems (loss of less than 5 points).
B8: Ambulant bowlers, who have a permanent and irreversible disability, have lost 10 points on the bench test, but have no noticeable impairment of function. (Loss of 0-1 points on technical assessment)
