Background: Straight leg raise (SLR) test is commonly used by physiotherapists to differentiate movement dysfunctions associated with neural tissue. Normative data regarding frequency and location of symptoms for SLRwith its various sensitizing additions is lacking in literature. Study design & Purpose: A cross sectional, observational study of normal responses to various sensitizing additions to SLR. Subjects: Eighteen asymptomatic volunteers (11 males, mean age 23.54± 1.65 years; 7 females, mean age 22.71± 1.54 years; total 36 lower limbs) were included based on convenience sampling. All subjects completed a screening examination to rule out pre-existing pathology of spine and lower extremity. Method: Following an initial application of sensitizing addition, SLR was administered. The sensitizing additions (plantar flexion + inversion, dorsiflexion, medial hip rotation, passive neck flexion, hip adduction, dorsiflexion + inversion, dorsiflexion + eversion) were added in a random order. Data collected include the sensation type and location on the body chart, P P and normal range of motion of SLR using modified reliable 1, 2 pendulumgoniometer. Result analysis: Sensation location&description are analyzed based on frequency distribution. Conclusion: Stretch, tingling, cramping and numbness are the types of sensations perceived along the distribution of the nerve component towhich the test is applied.
