Abstract
Objectives
Exercise therapy is recommended for low back pain (LBP) although the immediate effects on pain are highly variable. In 96 individuals with LBP this cross-sectional study explored 1) the magnitude of exercise-induced hypoalgesia (EIH), and 2) measures of pain sensitivity and clinical pain manifestations in individuals reporting a clinical relevant increase in back pain during physical activity compared with individuals reporting low or no increase in back pain during physical activity. Methods Cuff algometry was performed at baseline on the leg to assess pressure pain threshold (cPPT), tolerance (cPTT), and temporal summation of pain (cTSP). Manual PPTs were assessed on the back and leg before and after a six minute walk test (6MWT). Back pain was scored on a numerical rating scale (NRS) after each minute of walking. The EIH-effect was estimated as the increase in PPTs after the walk exercise. Results Twenty-seven individuals reported an increase of ≥2/10 in pain NRS scores during walking and compared with the individuals with
