A total of 66 patients (57.6% males and 42.4% females) suffering from LBP of lumbar spine origin out of the 78 referred to the selected medical facilities qualified for the study; Data were analysed using descriptive statistics and interferential statistic of independent t-test. Alpha level was set at 0.05.
