Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Repeated back extension exercises as described by McKenzie from prone position has been widely suggested for patients with lumbosacral radiculopathy (LSR). It has been reported to decrease radicular symptoms which could be due to the decompression effect of this exercise on the compromised nerve root. Moreover, mechanical traction have a debatable effect on lumbosacral patients with little evidence that supports its effectiveness. Thus, the investigators hypothesize that performing a combination of lumbar traction and repeated back extension exercise will improve the soleus H-reflex, pain, and function of lumbosacral radiculopathy patients.

Study Groups

repeated back extension exercise (McKenzie)

Repeated back extension exercise as described by McKenzie in prone position was performed of three sets of ten repetitions with one minute rest between the sets. The patient was asked to reach the maximum extension possible in all attempts and maintain this position for one second. The intervention was done 3 times per week for 6 weeks.

Group Type ACTIVE_COMPARATOR

Repeated back extension exercise (McKenzie)

Intervention Type OTHER

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.

Combined mechanical lumbar traction and repeated back extension exercise (McKenzie)

Participants allocated to mechanical lumbar traction received the McKenzie approach described above in combination with mechanical lumbar traction. The traction was applied using a 3D ActiveTrac table which is a motorized split table. Participants were placed in prone position and static traction was applied for 15 minutes at an intensity of 40% to 60% of the participant's body weight. At the end of traction intervention, participants continued with the McKenzie repeated back extension exercise intervention. The intervention was done 3 times per week for 6 weeks.

Group Type EXPERIMENTAL

Repeated back extension exercise (McKenzie)

Intervention Type OTHER

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

Intervention Type 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.
