Thirty low back pain patients with lumbar sacralization were divided into two groups, group A (extensor-flexor) and group B (flexor-extensor). In the 1st session of 6-week training group A started low back extensors strengthening and group B did flexor and in the 2nd session, the training programs were shifted between groups. The visual analog scale (VAS) was used to scale pain of low back of lumbar spine and knee. MicroFET3 was used to evaluate ROM. Cybex NORM was used to measure isometric strength of low back flexor, extensor and isokinetic strength of knee extensor at 60˚/sec, 120˚/sec and 180˚/sec. After 6-week training, low back maximal isometric strengths were significantly improved in both groups. Low back ROM was significantly improved in both groups. However strength and ROM not were significantly different between two groups. Quadriceps strengths were significantly improved in all 3 angular velocities of both right and left, particularly after extensor training. Low back extensor training was more efficient than flexor in pain control of low back and knee. Low back strengthening training for low back patients with lumbar sacralization may improve isometric strength, ROM and pain scale of low back, and further improve quadriceps isokinetic strength and knee pain scale, particularly in extensor strengthening.
