[Case-control study on comprehensive rehabilitation for postoperative pain after spinal surgery].
OBJECTIVE
To evaluate the effect of interferential electrical stimulation (IES) in pain relief after spine surgery.


METHODS
From January 2004 to December 2008, 166 patients after spine operation received pain treatment. All the patients were divided into two groups: the drug treatment group, which was the control group, including 46 cases, 22 patients were male and 24 patients were female, with an average age of (51.0 +/- 6.5) years; and the IES treatment group, including 120 cases, 50 patients were male and 70 patients were female, with an average age of (48.0 +/- 5.6) years. Before treatment, there were 4 patients with pain of Grade III in the control group, in which 3 patients had stenosis, 1 patient had spondylolisthesis; 42 patients had Grade II pain. In the IES group before treatment,17 patients had Grade II pain, in which 13 patients had stenosis, 4 patients had spondylolisthesis; 103 patients had Grade II pain. The preoperative and postoperative pains were evaluated and compared by the WHO Pain Criteria.


RESULTS
The composing of IES group with pain grade III, II and I were 1/96/23, 0/17/103, 0/0/ 120 at the 3rd day, the 7th day and the 14th day after treatment respectively, while in the control group they were 4/42/0, 2/ 44/0, 0/4/42 respectively. There were statistical differences between the two groups with Kruskal-Wallis test. The percent of mid and severe grade pain decreased much faster in IES group.


CONCLUSIONS
Interferential electrical stimulation (IES) therapy can improve patients' postoperative pain relief more quickly and reduce duration of hospitalization.
