Brief Medical History Overview
low back pain (i need an answer)
hi every one ,
i have an assignement and i am confused
, and i wish some one help me and ansewrs my questions .
a person was strengthening the abdominal muscles by making straight leg raising.he felt pain at the low back,and the leg cant be raised to 90 degree. when he tried to decrease the low back pain, he made trunk flexion from long sitting position and tried to touch his toes by his fingers, then he felt pain at the back of the thigh.
On biomechanical basis answer the following questions:
1. what is the cause of pain at the low back and at the thigh back ?
2. why cant the leg be raised till 90 degree?
3. if the person asked u about the proper way to exercise the abdominal muscled, what would u advise him to do and why?
i wait for the answer 
thanx
