Effects of deep heat therapy on the patients with chronic low back pain.

A randomized clinical trial was conducted in the Department of Physical Medicine & Rehabilitation, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh, from 1st April 2006 to 31st March 2007. A total of 102 patients of Chronic LBP were included in the study. Out of them, 42 (41.2%) were male and 60 (58.8%) were female and male: female ratio was 1:1.43. The mean age of the patients was 42.22+/-8.07 years. They were divided randomly into two groups by the way of lottery for the clinical trial. Group A was treated with short wave diathermy (SWD) and non steroidal anti inflammatory drugs (NSAID) and Group B was treated with placebo SWD and NSAID. After treatment the result was compared and student's 't' test was done to see the level of significance. There was significant improvement after treatment in both the group (P=0). In comparison between two groups, it was found that there was no significant improvement in pre-treatment, after 1st week and after 2nd week. Improvement was found in Group A than Group B after 3rd week (P=0.05). And the improvement was gradually increased in Group A in comparison to Group B. Finally, it was found that there was significant improvement in Group A than Group B after 6th week (P=0). From the present study, it may be concluded that both the treatment (NSAID and SWD) is effective for the treatment of Chronic LBP. But the patient may be more benefited if SWD is used as an adjunct to NSAID.
