To the Editor: The study by Dr Collacott and
colleagues1 contains sex bias and selection
bias; 19 of 20 subjects (95%) were men, 11 of 20 (55%) were disabled, and
6 of 20 (85%) were retired. It is possible that many such patients would deny
improvement from any therapy, to protect disability or monthly benefit claims.
It is also inappropriate to include a diagnosis of fibromyalgia, which is
controversial and not accepted by the majority of US physicians. 2 The statement implying that pain was caused by
spondylosis is not scientifically acceptable because all patients at mean
age 60 years display degenerative bone disease, which is generally asymptomatic.
