Weight-bearing characteristics of rats with lumbar radiculopathy (six days post-operation). Rats with NP alone had unbalanced weight-distribution, supporting significantly less weight on their affected limb relative to their contralateral limb (∀, P = 0.048). This weight-distribution was significantly different from pre-operative controls (*, P = 0.022). Rats with NP and sTNFRII treatment had improved weight distribution relative to rats with NP alone (^, P = 0.005). Data are presented as mean ± standard error.
