RESUMEN
AIM OF THE STUDY: To find out the efficacy of unilateral posteroanterior (PA) mobilization over type IA and type IIA sacralized lumbosacral transitional vertebrae in patients with low back pain with or without leg pain. RESEARCH DESIGN: experimental randomized control study. SAMPLE SIZE: 30 subjects, SAMPLING: simple random sampling. GROUP A - 15 subjects - self lumbar mobility and stretching exercises + Unilateral PA mobilization + hot pack. GROUP B - 15 subjects - self lumbar mobility and stretching exercises + hot pack. Before initiating treatment, subjects were assessed for dependent variables: Pain intensity by VAS, Forward bending and side bending ROM by modified finger to floor method with the help of an inch-tape and functions by Modified Oswestry Functional Disability Questionnaires. Post test measurements were taken after completion 2 weeks of therapy. The results of the study suggest that unilateral PA pressure is an effective mobilization method in reducing low back pain, improving ROM and related disability as compared to impairment based exercises alone in patients with low back pain with or without radiation to lower limbs having abnormally large transverse processes and hypomobile type IA and IIA lumbo-sacral transitional vertebrae.
