About this trial

The aim of the study is to investigate the effect of performing combined lumbar traction and repeated back extension exercise (McKenzie) on soleus H-reflex, pain, and disability in patients with lumbosacral radiculopathy. The main question that it aims to answer is:

Does the combination of lumbar traction and back extension exercise (McKenzie) improves soleus H-reflex, pain, and function in patient with lumbosacral radiculopathy? participants will be randomized into 2 groups: one group will include repeated back extension exercise (McKenzie Approach) without mechanical traction and the other group will include the same but in combination with mechanical traction.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patient with chronic unilateral lumbosacral radiculopathy (more than 3 months duration)

Age:35- 60 years

Both male and female

People with L5-S1 postero-lateral disc herniation or protrusion.

Disqualifiers

Subjects with lumbosacral Surgery.

Subjects with stenosis or scoliosis.

Subjects with cardiac problem or cancer.

Subjects with peripheral neuropathy.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Repeated back extension exercise (McKenzie)

    Other intervention

    repetitive back extension exercises in prone position with 1 minute hold on maximal back extension. 3 sets of 10 repetitions with 1 minute break between sets. The intervention was done 3 times per week for 6 weeks.

  • Mechanical traction

    Device

    The traction was applied using a 3D ActiveTrac table. This motorized split table applied static traction to the lumbar spine with the participant in a prone position. The intensity of the force of traction was 40% to 60% of the participant's body weight applied for 15 minutes. The intervention was done 3 times per week for 6 weeks.

Treatment groups

60 Participants
are divided into 2 treatment groups
Group A: repeated back extension exercise (McKenzie)Active comparator 1 intervention
Group B: Combined mechanical lumbar traction and repeated back extension exercise (McKenzie)Experimental treatment 2 interventions
