Objective To introduce a newly designed massage instrument, the Hand Grip T-bar (HT-bar) and use it to relieve chronic non-specifi c low back pain (nLBP) through deep cross-friction massage (roptrotherapy). Method 22 subjects (9 males and 13 females, aged 51.6±6.7) with chronic nLBP were allocated randomly to a Roptrotherapy group (n=12) and a Transcutaneous Electrical Nerve Stimulation (TENS) group (n=10). The Roptrotherapy group received deep cross-friction massage with the HT-bar, which was made of metal and had a cylinder for increasing weight and grooves for an easy grip. It was applied across the middle and lower back for 20minutes a day, 3 days a week for 2 weeks. Th e TENS group received TENS for 20 minutes a day, 5 days a week for 2weeks. Th e outcome was measured on the pain numeric rating scale (PNRS), by the Oswestry disability index (ODI),and by the Roland & Morris Disability Questionnaire (RMDQ) at pre-treatment, at immediate post-treatment and 2 weeks later. Th e application of the HT-bar was assessed by a questionnaire to 19 therapists. Results At post-treatment, immediately and 2 weeks later, both groups showed signifi cant improvement in PNRS,ODI and RMDQ. During the two weeks after post-treatment, however, the Roptrotherapy group improved in PNRS,ODI and RMDQ, but the TENS group did not. Over 80% of the therapists responded that the HT-bar was useful and comfortable. Conclusion Th is study suggests that deep cross-friction massage can be a benefi cial therapeutic technique and that the HT-bar can be a useful instrument in deep cross-friction massage for chronic nLBP patients.
