Hi Yaro, your assessment method will determine much of course. I have found the most persuasive and sensitive method is to attempt passive mobs at the considererd joint ( obviously for lateral thigh pain this will be L4 ) and discover if the two important signs are present , resistance and pain. If both are present then the joint will improve with Continuous Mobs till relaxation and comfort are restored, this may take up to ten minutes in some cases. A re-check of the complained of symptoms at the lateral thigh will then reveal a change , provided as is commonly true, referred events were taking place. This is almost always true in cases formerly thought to have been "ilio tibial band syndrome " where 'tightness'of the itb had been incorrectly assumed to be the initiative for pain.
