Table 7 Multiple linear regression analyses of physical activity measures against RMDQ change

From: Does a patient’s physical activity predict recovery from an episode of acute low back pain? A prospective cohort study

Predictor β (95% CI) p-value
RT3 VM/hr/wk change 0.00 (0.00 - 0.00) 0.81
*RT3VM change (low RT3 VM/hr group) 0.00 (0.00 - 0.00) 0.89
PAEE kcals/kg change (7D-PAR) −0.01 (−0.41 - 0.02) 0.45
**PAEE kcals/kg change (7D-PAR) 0.31 (−0.08 – 0.18) 0.27
Self –report of return to normal activities at 3 months −3.14 (−4.64 – 1.65) < 0.001
  1. β Regression coefficients adjusted for PA measures and age, BMI, occupation, activity levels prior to the onset of LBP, fear avoidance, levels of anxiety, depression and baseline RMDQ and pain levels.
  2. *Low RT3 VM/r/wk group defined as below the mean RT3 VM/hr/wk at baseline.
  3. **Low PAEE group defined as below mean PAEE kcals/kg at baseline.
