Summary

To determine the effect of high-power laser therapy on the size of herniated disc and functional outcome in patients with lumbosacral radiculopathy.

Detailed description

A herniated disc is a condition in which annulus fibrosus is damaged enabling the nucleus pulposus (which is normally located within the center of the disc) to herniate. It is a common cause of back pain. Unlike mechanical back pain, herniated disc pain is often burning or stinging, and may radiate into the lower extremity. Furthermore, in more severe cases, there can be associated with weakness or sensation changes. herniated disc injury may compress the nerve or the spinal cord causing pain consistent with nerve compression or spinal cord dysfunction, also known as myelopathy. Lumbosacral radiculopathy is a disorder that causes pain in the lower back and hip which radiates down the back of the thigh into the leg. This damage is caused by compression of the nerve roots which exit the spine at levels of L1- S4. The compression can result in tingling, radiating pain, numbness, paraesthesia, and occasional shooting pain. A combination of factors including pressure, inflammation, and an immune response seem to be implicated in the pathogenesis of both acute and chronic radicular pain. Pressure would not be a cause of pain, but rather of nerve dysfunction such as weakness and numbness, while the addition of both inflammation and immune response could explain the severe pain experienced by patients suffering from radicular pain. High power laser therapy (HPLT) is a new, non-invasive, painless, and powerful method with anti-inflammatory and reparative effects. HPLT has therapeutic benefits through photochemical, photothermal, and photomechanical mechanisms, possibly due to its potential for reducing inflammation, enhancing microcirculation, and stimulating immunological proteins and nerve regeneration and secretion of β-endorphins. MRI: It is the study of choice to visualize herniated disc. MRI findings will help surgeons and other providers plan procedural care if it is indicated. Disc protrusion and nerve root compression can be identified. As Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in the body. Imaging for diagnosis disc herniation are X-rays: These are very accessible at most clinics and outpatient offices. This imaging technique can be used to assess for any structural instability. If x-rays show an acute fracture, it needs to be further investigated using a computed tomogram (CT) scan or magnetic resonance imaging (MRI) .

Conditions

• Herniated Lumbar Disc

Interventions

Type	Name	Description
DEVICE	High power Laser Therapy	A total course protocol: 18 sessions, for 6 weeks ,3 sessions per week. Patients will receive High power Laser treatment. manually set to bio stimulation mode with high peak power (5 - 6 W), energy per impulse 150 mJ/c2, wavelength measuring 1064 nm, and spot beam diameter area of 1 cm2. The hand piece was positioned in contact with and perpendicular to the treated area with the patient inside lying position with knee to chest. Scanning will perform transversely and longitudinally paravertebral region on the lower lumbar area at the level of the disc concerned. Each session included three phases (fast scan, sensitive trigger points, slow scan) and had a total duration of 20 minutes. During each session, a total energy of 3000 J was applied through three phases of treatment.
DEVICE	physical therapy exercise program and hot pack	this group will receive the same selected physical therapy exercise program (45 minutes) and hot pack (10 min) for 18 session. All patients will attend the physical therapy clinic three times weekly for 6 weeks
