What type of joint mobilization involves a small amplitude glide at the beginning of the range of motion?

Grade 1 joint mobilization involves a small amplitude glide that occurs at the beginning of the range of motion. This type of mobilization is designed primarily to alleviate pain and reduce muscle guarding. It targets the joint's perception of movement without significantly stressing the surrounding tissues or exceeding the available range of motion.

The primary goal of a Grade 1 mobilization is to provide a neuromuscular response without pushing the joint into a discomfort zone, making it beneficial for patients who may have acute pain or inflammation. By carefully applying small oscillations at the start of the range, practitioners can help in managing pain and improving the patient's overall joint function without risking further injury.

Understanding the other grades is crucial for context. Grade 2 also targets the range of motion but involves larger amplitudes performed within the mid-range of the joint motion. Grade 3 and Grade 4 mobilizations engage larger movements that take the joint past the neutral zone into the end range, which primarily focuses on increasing mobility rather than pain management.
