Abstract

The purpose of this study was to compare the effects of exercise therapy, alternating cold and hot (ACH) therapy and low intensity laser (LIL) therapy in patients with chronic lumbar muscle strain (CLMS). Thirty-two patients were randomly allocated to four groups: exercise group, ACH group, LIL group, and combination group of exercise, ACH and LIL, eight in each group. Sixteen treatments were given over the course of 4 weeks. Lumbar muscle endurance, flexion and lateral flexion measures, visual analogue scale (VAS) and lumbar disability questionnaire (LDQ) were used in the clinical and functional evaluations before, immediately after, and 4 weeks after treatment. It was found that the values of endurance, VAS and LDQ in all groups were significantly improved from before to after treatment (P < 0.01). The combination group showed significantly larger reduction on pain level and functional disability than the other groups immediately and 4 weeks after treatment (P < 0.01). Pain level reduced significantly more in the ACH group than in the exercise group or the LIL group immediately and 4 weeks after treatment (P < 0.05). Lumbar muscle endurance and spinal ranges of motion in all groups were improved after treatment but there was no significant difference between any therapy groups. In conclusion, exercise therapy, ACH therapy and LIL therapy were effective in the treatment of CLMS. ACH therapy was more effective than exercise therapy or LIL therapy. The combination therapy of exercise, ACH and LIL had still better rehabilitative effects on CLMS.
