Following are the LLNT mentioned below:
1.Straight Leg Raise (SLR) Test:
This is a fundamental test where a supine patient’s straight leg is passively lifted until their symptoms are reproduced.
Positive Result:
Reproducing radicular symptoms between \(30 degree-70 degree) suggests involvement of the L4/5 or L5/S1 nerve roots.
2.Braggard’s Test:
This is an adjunct to the SLR test.After symptoms are reproduced, the leg is lowered slightly,the ankle is dorsiflexed, and the leg is lifted again.
If the original symptoms are reproduced with dorsiflexion,it is a positive test.
3.Slump Test:
This test is used to assess the neural structures within the vertebral canal and foramen.
Procedure:
The patient sits on the edge of a table and performs a series of movements:Slumps their back (flexes),places hands behind their back,tucks their chin to their chest and then actively extends their knee. Overpressure is applied at various stages.
Positive Result:
The reproduction of neurological symptoms like shooting pain or numbness indicates a potential issue.
4.Prone Knee Bend (PKB) Test:
This test can be used to assess for a positive response related to the femoral nerve.
Procedure:
The patient lies on their stomach and the clinician bends the patient’s knee.
Positive Result:
Reproduction of symptoms in the anterior thigh or groin can be a positive sign.
Why these Tests are performed?
Identify Nerve Involvement:
They help determine if a patient’s symptoms are due to nerve compression,irritation, or tethering, rather than just muscle or joint problems.
Diagnose Conditions:
They are used in diagnosing conditions like sciatica,which is often caused by a herniated disc or nerve root entrapment.
Inform Treatment Plans:
By identifying the source of the pain.Therefore,clinicians can create more targeted treatment plans that address the true cause of the symptoms.
