OBJECTIVE: to determine whether erector spinae muscle oxygenation (OXY) and blood volume (BV) during a progressive isoinertial lifting evaluation (PILE) are modified by an exercise therapy program. DESIGN: pre (E1) and post (E2) exercise therapy experimental design. SETTING: Hospital. PARTICIPANTS: 24 subjects with chronic low back pain (LBP group) and 24 healthy subjects (control group) were evaluated. INTERVENTIONS: exercise program. MAIN OUTCOME MEASURES: The control group was evaluated once and the LBP group was evaluated before (E1) the exercise therapy program and 28 days thereafter (E2). The maximal load lifted, total work and total power were determined using the PILE test. Continuous wave near-infrared spectroscopy (cwNIRS; NIMS, Philadelphia, PA)was used to measureOXY and BV during the PILE test. RESULTS: The maximal load lifted, total power and total work were significantly lower in the LBP group (-42 ±5, -46 ± 6 and -67 ±6% at E1; p < 0.05) than in the control group. In the LBP subjects, these parameters improved significantly after the exercise therapy program (+20 ±3, +56 ±4 and +61 ±5%; p < 0.05). At each submaximal power (i.e. 25, 50, 75 and 100% of maximal load lifted at E1), OXY and BV were significantly higher at E2 than at E1. One-half recovery time for muscle oxygenation was significantly higher in the LBP group (at E1 and E2) than in the control subjects. CONCLUSION: The findings in this study suggest that LBP subjects present an impairment in their capacity to deliver O(2) at the level of the erector spinae muscle which can be partly restored by an exercise therapy program.
