ABSTRACT
Objective: To investigate the influence of Swiss ball exercises on clinical efficacy and stability of lumbar vertebra in patients with protrusion of lumber intervertebral disc. Method: Thirty patients with non-acute protrusion of lumber intervertebral disc were divided by gender and clinics orders into control and exercises group. Roland Morris questionaire(RMQ) and visual analogue seale(VAS) were selected as pain assessment. Pain, abdominal and back muscle strength were assessed respectively before treatment, 2 and 4 weeks after Swiss ball exercises. Both Swiss ball exercises and lumbar traction were used in exercises group. Lumbar traction was used in control group. Result: Compared with before treatment, RMQ and VAS scores decreased significantly after 4 weeks in control and exercises groups (P<0.05, P<0.01). Compared with control, RMQ and VAS scores in exercises group decreased significantly after 2 and 4 weeks respectively (P<0.05, P<0.01). Compared with control, abdominal and back muscle strength in exercises group increased significantly after 2 and 4 weeks respectively (P<0.05, P<0.01). Conclusion: The low back pain symptom of patients with protrusion of lumber intervertebral disc decreased significantly and abdominal and back muscle strength increased significantly by beth Swiss ball exercises and lumbar traction. The stability of lumbar vertebra of patients with protrusion of lumber intervertebral disc increased significantly.
