The purpose of this study was to investigate the effects of suspension exercise on visual analogue scale (VAS), and isokinetic torque in chronic lower back pain (LBP) patients after 4 weeks. The thirty female subjects aged between 20 and 22 years (mean 20.76 years) were recruited from the H University in Korea. The subjects were randomly divided into three groups : the Supine group (0°G; n=10), the suspension 30° group (30°G; n=10), and the suspension 60° group (60°G; n=10), respectively. Each group completed a 3-minute × 3-set, 3 days/1 week for 4 weeks suspension exercise protocol at 0°, suspended -30°, or suspended -60°, respectively. Prior to comparison of VAS and isokinetic torque variables in 60°/s, the one-way ANOVA was performed for comparison of the anthropometric data among 3 groups. And then to examine the differences of the variables of 0°G, 30°G, and 60°G, a 3×2 mixed-model analysis of variance was completed. Also, we gained delta % between pre- and post-data. These delta % analyzed through non-parametric Kruscal-Wallis test and Scheffe' post hoc test. In the present results, suspension exercise were significantly decreased the expression of VAS parameters, and much more suppressed the expression of VAS parameters in the 60°G. In the isokinetic torque, suspension exercise were significantly increased the extensor peak torque (PT) and peak torque % body weight (PTBW), and much more enhanced the PT and PTBW in the 60°G. From our results, it can be inferred that suspension exercise can provide the protective LBP effect against LBP-induced pain and decreased isokinetic toque in extensor ability of LBP patients. Thus, the -60° suspension exercise is recommended for patients with chronic LBP.
