This study aimed at assessing the effects of trunk strengthening exercises on chronic, mechanical low-back pain and compare the use of isokinetic dynamometer and therapeutic ball. Nineteen patients with chronic low back pain were randomly divided into two groups of trunk muscle strengthening, namely the ball group (5 men and 5 women, mean age 31,2±8,2) and the dynamometer group (2 men and 7 women, mean age 37.9±11.2). Patients attended two weekly sessions during three months and were evaluated before and after treatment as to pain (visual analog scale), functional disability (Roland Morris questionnaire), mobility (Schöber and fingertip-to-floor tests), and trunk concentric extensor and flexor muscles force (by the isokinetic dynamometer). The parameters selected to evaluate muscular performance were: peak torque, peak torque angle, power, work, acceleration time, and flexor/extensor ratio. Data were statistically analysed and the significance level set at 5%. A significant (p
