Bargraphs showing the mean (± SEM) durations of (i) Dominant, (ii) Non-social, (iii) Social and (iv) Submissive behaviours on pre-injury days 3–5 and post-injury days 1–3 and 4–6, in: (1) behaviorally tested control rats (n = 11); (2) sham-injured control rats (n = 7); (3) Pain alone following CCI (n = 6); (4) Pain and Disability following CCI (n = 7); and (5) Pain and Transient Disability following CCI (n = 5). Significant difference between pre- and post-injury days (Fisher's least significant difference) are shown: *P < 0.05.
