What are isokinetic tests?

What are isokinetic tests?

Isokinetic testing is a strength test for the muscles around the knee using specific equipment. It’s used to compare the strength of the affected knee against the unaffected leg. This test is useful if you have a knee injury, are recovering from surgery or suffering from a long-term problem with your knee.

What is the isokinetic strength test?

Strength Testing Using Isokinetic Dynamometry Isokinetic dynamometers are able to test the strength (torque) and power of different muscle groups. The equipment can be modified in order to assess a number of different upper and lower body limb motions.

What test is performed to see if ACL is intact?

The Lachman test is used to diagnose an anterior cruciate ligament (ACL) tear. The ACL is one of four major knee ligaments that contribute to the stability of the knee joint. An ACL tear often occurs as a sport-related injury and may require surgical reconstruction for treatment.

Is isokinetic testing considered functional testing?

FCEs use a test battery as described in the name, that is, they are functional and attempt to evaluate capacity of overall human performance. There have appeared in the literature some works that indicate that isokinetic testing is related to functional performance.

What is isokinetic knee strength?

Isokinetic dynamometry Isokinetic movement is defined by maintaining an angular velocity of constant movement throughout the joint path. The current isokinetic dynamometry system allows evaluating in both concentric and eccentric modes of exercise.

What is isokinetic exercise used for?

Isokinetic exercise is a form of strength training that can increase muscle tone, strength, and endurance. It can also help improve balance and coordination, and boost metabolism. Strength training makes everyday activities easier to perform, and can increase your athletic performance.

What is isokinetic muscle action?

Definition. An isokinetic muscle contraction occurs when the velocity of the muscle contraction remains constant while the length of the muscle changes. The force exerted by the muscle is not fixed, and can vary depending on the position of the joint in its range of motion and the participation effort of the subject.

What is the gold standard for ACL?

BPTB has historically been considered the “gold standard” for ACL reconstruction. The BPTB autograft is frequently chosen because of its excellent clinical results and high level of patients satisfaction in long term followup.

What is an example of isokinetic muscle contraction?

Outside of a gym or physical rehabilitation setting, isokinetic contractions are rare. The closest example may be swimming the breaststroke in which water provides constant resistance to the movement of your arms.

What is an example of isokinetic?

One example of an isokinetic exercise is a stationary bike that responds to a constant leg movement by the user. The resistance offered by the stationary bike may vary, while the speed of limb motion and subsequent revolutions per minute stays the same.

What is an example of an isokinetic muscle contraction?

What is an example of an isokinetic exercise?

Is isokinetic testing useful in rehabilitation patients after ACL reconstruction?

INTRODUCTION. Isokinetic testing is a commonly utilized tool for the assessment of muscular strength in orthopedic and sports medicine setting abroad, but in our country or region were poor documented studies about it. In rehabilitation patients after ACL reconstruction isokinetic testing we use it for evaluation and treatment planning.

How do you interpret isokinetic results?

Another way to explore isokinetic results is to divide range of motion into three sections. The first is time to attain velocity (TTAV), the second is load range (LR) wherein specific velocity defined is sustained and finally deceleration time (DT).

Does isokinetic dynamometer test for knee flexion?

Testing was performed on a Biodex System 4 isokinetic dynamometer in concentric mode at 60, 120 and 300 °/s, for knee flexion and extension. Statistically significant differences were seen for extension ROM at 60 °/s where ROM was greater in the control group.

What is the frequency of isokinetic testing?

Testing was performed in the concentric isokinetic mode at 60, 120 and 300 °/s, for knee flexion/extension with a sampling frequency of 100 Hz. Participants were instructed to not perform any physical activities on the day of testing.
