The Resisted Isometric Movement testing was an examination developed by Cyriax. It was originally called resisted movements, and is sometimes known as the resisted isometrics.
Contractile structures: Structures that can shorten and elongate in length like a muscle
Inert structures: Structures in the human body that cannot shorten or elongate in length. Eg: ligaments, tendons, capsule, bursa.
Procedure:[edit | edit source]
- The joint is positioned in mid range, keeping the inert tissues off of stretch and there must be no movement at the joint
- Muscles other than the testing muscles must not be included. Hence trick movements from surrounding muscles must be avoided.
- The patient must be instructed to exert a maximal effort during the test.
- Examiner must be attentive in identifying pain or weakness that would be due to a nerve involvement
Weakness: Minor weakness need to be detected with the hands well positioned to offer resistance and counter pressure.
Interpretation[edit | edit source]
Strong and painless: No lesion in the contractile structure
Strong and painful: Minor lesion in a part f the muscle or tendon and its attachment.
Weak and painless: There could be a complete rupture of the muscle or tendon, but most commonly might be a malfunction of the nerves. This impaired function of the nerve leads to muscle weakness.
Weak and painful: Serious impairment, like a secondary deposit or a fracture might be present. However, if a patient is reluctant to replicate the severe pain it may appear as apparent weakness
Painful on repetition: Intermittent claudication could be the reason a the movement is painless and strong initially but hurts on repetition.
All resisted movements painful: A gross lesion lying proximally, which would mostly be a capsular leision,
