L/S Special tests
| Question | Answer |
|---|---|
| Lasegue's test (SLR) purpose | Identifies dysfunction or neurological structures supplying lower limb |
| Lasegue's test (SLR) description | Pt supine, hip IR and add, and knee extended, examiner flexes hip until pain/tightness in back or back of leg. Examiner slowly drops leg back (extends it) slightly until pt feels no pain/tightness. Pt then asked to flex neck or examiner DF pt's foot. |
| Lasegue's test (SLR) results | Reproduction of pathological neurological symptoms when foot is DF |
| Femoral nerve traction test purpose | identify compression of femoral nerve |
| Femoral nerve traction test description | pt lies on unaffected side. Unaffected limb slightly flexed at the hip & knee. Examiner grasps the pt's affected limb & extends the knee while gently extending the hip (15degrees). Pt knee is then flexed on affected side to further stretch the femoral n. |
| Femoral nerve traction test result | neurological pain radiates down the anterior thigh if the test is positive |
| Valsalva maneuver purpose | identify a space occupying lesion |
| Valsalva maneuver description | Seated pt asked to take a breath, hold it, and then bear down as if evacuating the bowels |
| Valsalva maneuver result | If pain increases, indicates intrathecal pressure |
| Babinski test purpose | Identifies UMN lesion |
| Babinski test description | The examiner runs a pointed object along plamnatar surface of patients foot |
| Babinski test result | Positive: suggests UMN lesion. Reflex demonstrated by extension of big toe and abdution (splaying) of the other toes |
| Quadrant test purpose | Identify compression of neural structures at the intervertebral foramen and facet dysfunction |
| Quadrant test description | Pt stands and extends the spine while examiner controls the movement by holding pt's shoulders. Overpressure applied inextension while side flexion and rotation to the side of pain. Mvmt continued until limit reached/symptoms produced |
| Quadrant test result | Positive: max narrowing of intervetebral foramen and stress on facet joint to side on which rotation occurs. Positive if symptoms are produced |
| Stork standing test purpose | Identifies spondylolisthesis |
| Stork standing test description | Pt stands on 1 leg and extends the spine while balancing on the leg. Test repeated with pt standing on the opposite leg |
| Stork standing test result | Positive: indicated by pain in the back and associated with pars interarticularis stress fracturev (spondylolisthesis). If stress fracture is U/L, standing on ipsilateral leg causes more pain |
| Mckenzie's side glide test purpose | differentiates between scoliotic curvature verses neurological dysfunction causing abnormal curvature of the trunk |
| Mckenzie's side glide test description | Pt stands. Examiner grasps pt's pelvis with B hands and places shoulder against lower thorax. Using shoulder as block, the examiner pulls pelvis toward the examiner's body. The position help 10-15 sec, then the test repeated on other side |
| Mckenzie's side glide test results | positive: increased neurological symptoms on affected side |
| Bicycle (Van Gelderen's test) purpose | differents between intermitten claudication and spinal stenosis |
| Bicycle (Van Gelderen's test) description | Pt on ex bicycle & pedals against resistance upright to accentuate lordosis. Pain into butt & posterior thigh occurs, followed by tingling in the affected LE, the 1st part is positive. Then lean forward and pedal. If pain subsides, 2nd part is positive. |
| Bicycle (Van Gelderen's test) results | Patient with intermittent claudication of LE typically experiences an increase in symptoms with continued exercise regardless of position of the spine |
| Prone instability test purpose | Test for likelihood of a patient with LBP responding to stabilkization exercise program |
| Prone instability test description | Pt prone so trunk rests on bed and feet on floor, with hips flexed and trunk relaxed. PT PAs over symptomatic SP, and reproduction of sympt noted. Release PA, and patient lifts feet off producing global co-contract of abdomainl, ES, glutes. |
| Prone instability test results | PA with feet up, decrease in symp. = positive. Pt with LBP, who present with negative prone instability test, are unlikely to respond to a stabilization exercise program |
