Brief summary

this study was conducted to investigate the effects of lumbar extension traction in patients with unilateral lumbosacral radiculopathy due to L5-S1 disc herniation. Sixty four patients with confirmed unilateral lumbosacral radiculopathy due to L5-S1 disc herniation and lumbar lordotic angle measured less 39 degrees were randomly assigned to traction or a control group.The control group (n=32) received hot packs and interferential therapy, whereas the traction group (n=32) received lumbar extension traction in addition to hot packs and interferential therapy. Absolute rotatory angle (ARA), back and leg pain rating scale, Oswestry Disability Index, modified Schober test, H reflex (latency and amplitude) and intervertebral movements were measured for all patients at three intervals (before treatment, after 10 weeks of treatment, and at follow-up of six months). There was a significant difference between the traction and control groups adjusted to baseline value of outcome for all measured variables at 10 weeks post treatment with respect to ARA (P=0.000), ODI ( P=0.002), back and leg pain (P=0.009), (P=0.005), modified Schober test (p=0.002), latency and amplitude of H reflex(p=0.01), ( p=0.000), intervertebral movements (p>0.05) and at follow-up for all previous variables (p>0.05). Lumbar extension traction in addition to hot packs and interferential therapy decreased pain, disability and H reflex latency while increased lumbar flexibility, H reflex amplitude, and segmental intervertebral movements 100 patients were initially screened.After the screening process, 68 patients were eligible to participate in the study. patients registered but Not randomized (n=4) Due to early discharge for non -medical reasons and Total number of patients registered (n=64) randomization.

Interventions

Patients received hot packs ( hydrocollator). A hydrocollator pack is a silica gel filled pack that is soaked in hot water for a minimum of 20 minutes. The gel pack is wrapped in towels 3 to 5 layers underneath and 1 on top to provide prolonged moist heat. During application, patients were asked to adopt prone position the hot packs was applied on the lumbosacral region for 15 minutes.This conventional treatment was to be repeated three times per week for 10 weeks. interferential therapy.

During interferential application, patients were asked to adopt prone position. Interferential treatment was introduced using electrotherapy device. The interferential therapy was delivered at the lumbosacral region with an amplitude-modulated constant frequency of 100 Hz and a pulse duration of 125 micro seconds due to its analgesic effect, for a 20-minutes.This conventional treatment was to be repeated three times per week for 10 weeks. The patients additionally received lumbar extension traction. In this type of traction, there is vertical load applied by a posterior padded strap between the upper torso and lower pelvis while the upper torso and femur were stabilized by other straps. The patients were having traction three times a week for ten weeks. The traction began at three minutes/session, increased one minute/session to 20minutes, at which time traction was applied for 20minutes/session all treatments were administered simultaneously over the10 weeks.

Inclusion criteria

patients with absolute rotatory angle was less than 39 degrees. then a participant was referred to the study. patients had a confirmed chronic unilateral lumbosacral radiculopathy associated with L5-S1 lumbar disc prolapse , and duration of symptoms more than 3 months to avoid acute stage of inflammation. Patients underwent magnetic resonance (MR) imaging, which detected disc lesion corresponding to the S1 nerve root. All patients had unilateral leg pain with mild to moderate disability according to ODI (up to 40%). They all had side-to-side H reflex latency differences of more than 1msec.

Exclusion criteria

included previous history of lumbosacral surgery, metabolic system disorder, cancer, cardiac problems, peripheral neuropathy or history of upper motor neuron lesion, spinal canal stenosis, rheumatoid arthritis, osteoprosis, inability to tolerate lumbar extension position, spondylolisthesis , scoliotic deformity and any deformity of lower extremity that may interfere with global alignment.
