Summary

This study attempts to answer the following research question: what is the combined effect of low level laser therapy and neural mobilization on lumber disc prolapse in decreasing pain, improving functional disability, improving neural mobility and improve lumber flexion mobility?

Detailed description

Lumbar disc prolapse is a movement of disc material out of the intervertebral disc space. Protruded nucleus comes in contact with the surrounding nerves, causing their compression that in turn results in severe radicular pain. The purpose of this study is to assess the combined effect of low level laser therapy and neural mobilization on lumber disc prolapse, this assessment will be done through assessment of pain, functional disability, neural mobility and lumber flexion mobility. Subjects and Methods : 40 Patients with lumber disc prolapse and radiculopathy based on clinical examination by orthopedic surgeon and (MRI) imaging aged between 30 and 50 years . This study will be a double blinded randomized controlled trial . After including patients in the study, they will be randomly assigned into 2groups : Control group (A) (n=20): will receive placebo laser therapy plus neural mobilization. Experimental group (B) (n=20): patients will receive low level laser therapy plus neural mobilization Both control group and experimental group receive infrared as warming up before treatment for12 sessions, each for 15 min, 3 days per week, for a period of 4 weeks . All patients will perform all assessment procedures accurately (straight leg raising test, slump test and Schober's test ) and will fill (VAS) and (ODI) accurately. Mobilization will be through using slump sitting maneuver (Both techniques slider and tensioner).Neural mobilization will be applied in form of 3 sets every set 10 repetitions and the end Position was hold for 5 seconds and the rest between sets was 5 minutes. All the patients will receive 12 sessions (3 times/week for 4 weeks). : patients receive LLLT will lie in side lying on the non-affected side which is opposite to the side of radicular pain, hip and knee in flexion 90.Twenty points were established for treatment, 12 over the lumbar spine, at the same Side of the radicular pain and 8 points over thigh for 3 sessions per weak for 4 Weeks. The hypotheses for this study are: 1. There will be significant improvement in pain after combination of LLLT and neural mobilization. 2. There will be significant improvement in functional disability after combination of LLLT and neural mobilization. 3. There will be significant improvement in lumber flexion mobility after combination of LLLT and neural mobilization. 4. There will be significant improvement in neural mobility after combination of LLLT and neural mobilization.

Type	Name	Description
DEVICE	Low Level Laser Therapy by (Eme Physio, Lasermed 2200), GaAs laser, 1 cm2 beam area,7,000 Hz, 17 mW, 1 J/cm2, Pesaro, Italy)	(Eme Physio, Lasermed 2200), GaAs laser, 1 cm2 beam area,7,000 Hz, 17 mW, 1 J/cm2, Pesaro, Italy) . Patient lies in side lying on the non-affected side which is opposite to the side of radicular pain, hip and knee in flexion 90. Twenty points were established for treatment, 12 over the lumbar spine, at the same Side of the radicular pain, from l2 to s1 vertebra, distance between these points is 2 cm. In the thigh, eight points were marked at equal distances from each other, four in the path of l5 root and four in the path of s1 root from hip to knee. The leaser probe is held in 90 degree over the skin with complete skin contact
PROCEDURE	neural mobilization	Mobilization will be through using slump sitting maneuver (Both techniques slider and tensioner. •The slider neurodynamic mobilization technique: The patient moves actively and conversely from a position of neck and trunk flexion, knee flexion, and ankle plantar flexion, to a position of neck and trunk extension, knee extension and ankle dorsiflexion The tension neurodynamic mobilization technique: The patient moves actively and conversely from a position of neck and trunk extension, knee flexion, and ankle plantar flexion, to a position of neck and trunk flexion, knee extension, and ankle dorsiflexion
OTHER	placebo laser therapy	patients receive the same treatment on the same area as experimental group for the same period without turning on the device.
