Abstract: Objective To investigate the effects of vacuum suction stereo-dynamic interferential electrotherapy and McKenzie therapy on lumbar disc herniation in aged patients.Methods 70 aged patients with lumbar disc herniation are randomly divided into two groups,experiment group and control group.Each contained 35 patients.Both are treated 15 min daily with the SD5101 therapeutic.For the experiment group,McKenzie therapy is employed 3～4 times per day additionally.They were evaluated with Graded Efficacy For Relieving Lumbar Pain before and after treatment.Follow-up observation lasted for 10 months to record the time of treatment and recurrence rate of both groups.Results For short-term curative effect,no statistical differences were observed between these two groups(P>0.05).For the curative effects on single-segment or multi-segment lumber disc herniation,statistical differences were observed before and after treatment in each group(P<0.05),but were not between them(P>0.05).The curative effects are negatively correlated with the course of treatment(For experiment group:r=-0.72;For control group:r=-0.64).No statistical differences were observed between these two groups in terms of the total correlation coefficient(P>0.05).The time of treatment in experiment group is shorter than that in control group(P<0.05).The recurrence rate in experiment group is lower than in control group(P<0.01).Conclusion Vacuum suction stereo-dynamic interferential electrotherapy combining with McKenzie therapy is an efficient method in treating aged patients with lumbar disc herniation.
