Straight Leg Raise Test with Braggard's Sign
- Tests for sciatica, sciatic nerve vs. hanstrings causing the problem
- Tests if client is experiencing sharp pain in back or if client has nerve pain down their leg, often to plantar surface of their foot.
- Client is supine. Therapist stands on the side of the table to be tested (side of leg nerve pain) and grasp's the clients heel and brings leg into hip flexion w/ knee extended @ 70-75 degrees, the sciatic nerve is streached. If pain increases before 70 degrees, lower the leg from point of pain about 10-20 degrees and then client dorsiflexes the foot and flexes the head and neck (Braggards sign)
- Positive test for nerve involvement and or hamstring contracture if pain is increased or there is numbness in either leg. If numbness again increases with Braggard's, disc involvement is present. If pain or numbness does not return, hamstring contracture is suspect.
