In one studied the effect of patient-specific three-dimensional lumbar traction on pain and functional disability in individuals with lumbar intervertebral disc prolapse. Twenty-five participants (age range: 34-67 years) diagnosed with lumbar intervertebral disc prolapse were included in this study. Patient-specific three-dimensional lumbar traction was given as three sessions per week for the duration of one month. All participants completed a 10-cm visual analog pain scale and pain pressure threshold to assess pain and the Oswestry disability index to assess the functional disability. Twelve sessions of patient-specific three-dimensional lumbar traction promoted a reduction in pain and improvement in functional disability among subjects with lumbar intervertebral disc prolapse.Another studied to evaluate the effectiveness of traction in improving low back pain, functional outcome, and disk morphology in patients with herniated intervertebral disks. They included randomized control trials which involved adult patients with low back pain associated with herniated disk confirmed by magnetic resonance imaging or computed tomography, compared lumbar traction to sham or no traction, and provided quantitative measurements of pain and function before and after intervention. Methodological quality was assessed using the physiotherapy evidence database (Pedro) scale and Cochrane risk of bias assessment. Compared with sham or no traction, lumbar traction exhibited significantly more pain reduction and functional improvements in the short term, but not in the long term.~In Pakistan most of the physiotherapists used the two-dimensional traction bed for lumbar traction. There is insufficient study on Three-dimensional Traction unit. And there is no literature review is available on comparison of the 2d and 3d traction. To the best of researcher's knowledge, it can be concluded that insufficient literature is available on th
The aim of study will be comparative effectiveness of the 2d and 3d lumbar traction on pain and functional disability in lumbar radiculopathy. This study will be useful for the physiotherapists to know which traction equipment will be more effective for the treatment of the lumbar radiculopathy
