The therapists compared two groups of patients in the same age range (19 to 55 years). One group had whiplash injuries at least six months ago. The second group had degenerative changes as a result of disc problems or arthritic bone spurs.
Findings showed patients in both groups had a 25 to 35 per cent decrease in total neck range of motion. This represents a moderate-to-severe degree of neck disability.
A closer look at the data did show that the group with degenerative changes had a slightly higher severity of disability. Whiplash patients tend to have greater loss of motion in extension whereas patients with degenerative changes had a more global loss of motion in all directions.
Pain more than structure or anatomy appeared to be the real factor limiting function in these two groups. So you ladies can compare pain levels, function, and range of motion and get a pretty good idea of which condition is more limiting.
