Is isokinetic strength testing done with isokinetic dynamometer?

The dynamometer supports and aligns a limb while you push or pull against resistance. It adjusts the resistance so the selected joint moves at a set speed, rather than allowing the limb to accelerate freely. The clinician can compare force through the movement and may compare one side with the other or reassess the same muscle group later.

The appointment usually includes an explanation, positioning, practice efforts and recorded efforts. Results are interpreted alongside pain, range of motion, technique, fatigue and the reason for testing. A number alone does not describe how safely you perform everyday activities.

Wear clothing that allows the joint to be positioned and tell the clinician about recent surgery, pain, swelling, dizziness or a condition affecting movement. Follow the warm-up and effort instructions, keep the tested body part aligned, and report sharp pain rather than forcing through it.

Avoid an unusually hard workout before the appointment unless your clinician has advised it. Bring details of relevant exercises, injuries and goals so the result can be interpreted in context. The test may be adapted or postponed if symptoms make maximal effort unsuitable.

Tell the clinician immediately if testing causes sharp or escalating pain, a feeling of giving way, unusual shortness of breath, faintness, chest discomfort, new numbness or sudden weakness. Seek medical help after the appointment for persistent severe pain, marked swelling, loss of function or symptoms that do not settle with the advised rest.

Which muscle groups and movement will be tested? Is maximal effort appropriate for my injury and health? How will pain or limited range affect the result? Will both sides be compared? How will the findings change my exercise programme, and when should the test be repeated?
