Restricted activity and persistent pain following motor vehicle collision among older adults: a multicenter prospective cohort study

Table 3 Unadjusted relationships between three measures of restricted activity at 6 weeks and pain and functional outcomes at 6 months. Values are reported as unadjusted mean (SE)

^a Mean severity of MVC-related pain (0–10 scale) 6 months after MVC, N = 147
^b Mean score (0–10 scale) 6 months after MVC, N = 147
^c Mean change in score (0–18 scale) from baseline to 6 months after MVC, with higher value indicating greater difficulty with ADLs, N = 146
^d Mean change in score (0–12 scale) from baseline to 6 months after MVC, N = 138
^e Defined as a ≥ 25 point decrease in Physical Activity Score for the Elderly (PASE) during the 6 weeks following ED visit
