Randomized Controlled Trial Comparative Study Clinical Trial
The effect of a fear-avoidance-based physical therapy intervention for patients with acute low back pain: results of a randomized clinical trial.
A randomized clinical trial with 4-week and 6-month follow-up periods. ⋯ Patients with elevated fear-avoidance beliefs appeared to have less disability from fear-avoidance-based physical therapy when compared to those receiving standard care physical therapy. Patients with lower fear-avoidance beliefs appeared to have more disability from fear-avoidance-based physical therapy, when compared to those receiving standard care physical therapy. In addition, physical therapy supplemented with fear-avoidance-based principles contributed to a positive shift in fear-avoidance beliefs.

The authors investigated the association of L5 proximal nerve root injury with spinal cord neuronal apoptosis (histologic) and whether exogenous erythropoietin therapy might reduce apoptosis/or pain (behavioral). ⋯ Our findings indicated that L5 proximal nerve root crush increased neuronal apoptosis in the superficial dorsal and ventral horn that correlated with mechanical allodynia. Exogenous recombinant human erythropoietin facilitated receptor-mediated neuroprotection of spinal cord neurons and faster recovery from mechanical allodynia. Erythropoietin may be a potential therapeutic factor for patients with low back pain by providing pain relief and neuroprotection.
