Resisted Isometric Testing

Resisted isometric testing involves having a patient contract a muscle isometrically while the examiner resists movement. This helps determine if a lesion involves contractile tissues like muscle or tendon, or non-contractile tissues like joints. Increased pain with contraction suggests contractile tissue involvement, while pain with accessory motions suggests non-contractile tissues. Test results are classified as strong/painful, strong/painless, weak/painful, or weak/painless to localize pathology.

SOLUTION

RESISTED ISOMETRIC
CONTRACTIONS
What is resisted isometrics?

Resisted isometric contractions are the


movements consists of strong, isometric,
voluntary muscle contraction.
What is the aim of testing?

It is used primarily to determine weather the


lesion is in the contractile tissue such as
muscle or tendons or into the bone, or
involvement of inert tissues such as joint
surfaces, joint capsule or ligaments.
How to test it?

The joint is put in the neutral or resting


position so that minimal tension is placed on
the inert tissues.

 The patient is asked to contract the muscle as


strongly as possible while examiner resists to
prevent any movement from occurring.
INTERPRETATION

 Increased pain during isometric contraction,


caused by shortening of the muscle and
pulling of the tendon helps to confirm the
involvement of contractile tissues.
 Sometimes pain occurs with releasing of
contraction and lengthening occurs, this
would also be positive finding for lesion in
contractile tissue.

 The lack of pain during resisted isometric


testing, pain noted during limited accessory
motions, capsular pattern and particular end
feel during passive ROM help to confirm the
involvement of inert tissues.
RESULTS OF RESISTED
ISOMETRIC TESTING

1. Strong and painless:- There is no lesion or


neurological deficit involving the
tested muscle and tendon.
2. Strong and painful:- There is minor lesion
of the tested muscle or tendon.
3. Weak and painless:- There is a disorder of
the nervous system, neuromuscular junction,
or a compete rupture of the tested muscle or
tendon, or disuse atrophy.
4. Weak and painful:- there is a serious, painful
pathology such as a fracture or neoplasm.
Other possibilities include an acute
inflammatory process that inhibits muscle
contraction, or a partial rupture of the tested
muscle or tendon.
Example:-

 Bicipital tendinitis: Painful resisted isometric


testing

 Adhesive capsulitis of GH joint: Painless resisted


isometrics
