Joint Mobilization

Joint mobilization or joint mob is a manual technique to improve joint accessory motion and to reduce joint pain by using specific oscillatory or sustained stretch technique. Mobilization is a manual therapy intervention and is classified by five grades of motion, each of which describes the range of motion of the target joint during the procedure.

Grade 1 - Activates Type I mechanoreceptors with a low threshold and which respond to very small increments of tension. Activates cutaneous mechanoreceptors.

Grade 2 - Similar effect as Grade I. By virtue of the large amplitude movement it will affect Type II mechanoreceptors to a greater extent.

Grade 3 - Similar to Grade II. Selectively activates more of the muscle and joint mechanoreceptors as it goes into resistance, and less of the cutaneous ones as the slack of the subcutaneous tissues is taken up.

Grade 4 - Similar to Grade III. With its more sustained movement at the end of range will activate the static, slow adapting, Type I mechanoreceptors, whose resting discharge rises in proportion to the degree of change in joint capsule tension.

Grade 5 - This is the same as joint manipulation. Use of the term Grade 5 is only valid if the joint is positioned near to its end range of motion during joint manipulation.

I have uploaded videos of joint mobilization for each joint. Below is the link. So, happy studying...! =D
