Fig. (2) Sciatic pain and pain reduction. (A) Patients have been treated with high-tone electrical muscle stimulation (HTEMS; n=59) or transcutaneous electrical nerve stimulation (TENS; n=41). Each treatment modality was administered for a period of 45 min per day, 5 times per week, within 7 days, in the first phase. The treatment effect of short-term application of HTEMS of 10 ± 17 (10 [0-20]; p<0.001) mm and 4 ± 15 (0 [0-10]; n.s.) mm with TENS in pain intensity on the VAS was significantly different between both groups (p=0.046). (B) After crossover and wash-out phase, patients were treated with the other treatment (i.e., HTEMS; n=40 & TENS; n=54) for a period of 45 min per day, 5 times per week, within 7 days, in the second intervention phase and a reduction of 13 ± 15 (10 [0-20]) mm VAS (p<0.001) with HTEMS treatment and of 7 ± 14 (10 [0-20]) mm VAS (p=0.0015) with TENS was achieved. *p<0.05; #p<0.05; ###p<0.001; H1: first intervention phase with HTEMS; H2: second intervention phase with HTEMS; n.s.: not significant; T1: first intervention phase with TENS; T2: second intervention phase with TENS; VAS, visual analog scale.
