Effectiveness of Lumbar Belt on Pain and Lumbar Mobility in Patients with Chronic Low Back Pain- An Experimental Study
Main Article Content
Abstract
Background - Low back pain is more common now a days. But there is limited evidence of efficiency of lumbar belt for treatment of low back pain1. There is also lack of methodology in the studies reported on the efficiency of the device.
Objective - To evaluate the effectiveness of lumbar belt in chronic low back pain and to evaluate the mobility and disability of the trunk after using lumbar belt for chronic low back pain.
Materials and Methods- 32 subjects were included in this study with age group between 25 to 45 years. Subjects was divided in to two groups through lottery method. Data collection sheet was used to obtain demographic details such as patients age, gender, address, contact details. Before the treatment (at day 0) and after treatment (at days 15), Pain of back was determined by Visual analogue scale (VAS), disabilities of the spine determined by modified Oswestry disability index (MODI) and spine mobility (ROM) measured by modified Schober’s test (MST) in both groups. Both groups were treated by IFT (4P) and Hot pack over back for 15 mins and experimental group was advised to wear lumbar belt during the treatment period as daily minimum of 8 hours except during sleeping time.
Result- Paired T – test and 2- tailed test was used to analyse the data, since the P-value of paired sample test for individual group (pre and post scores) of VAS and MODI is <0.01, so there is significant difference between pre and post scores. But, the P-value of pre and post score of MST for experimental (belt wearing) group is not <0.01, so, there is no significant difference of mobility of spine in experimental group. In 2 – tailed test the P- value of VAS and MODI is not < 0.01, so, there is no significant different in pain and disability after compared in between both groups. But, in 2- tailed test the p-value is < 0.01 in MST after
compared in between both groups. Therefore, we can say that there is a significant difference in the amount of change in MST (cm) between the Experimental and control groups.
Conclusion-The present study provided evidence to prove that use of lumbar belt in chronic low back pain reduce trunk mobility.
