Trigger Point Dry Needling and Proprioceptive Exercises for the Management of Chronic Ankle Instability: A Randomized Clinical Trial

Figure 4

Trigger point dry needling (TrP-DN) applied over the lateral peroneus muscle. With the patient in side-lying position, the needle was inserted into the skin over the TrP until the first local twitch response was obtained and moved up and down (2 to 3 mm vertical motions with no rotations) at approximately 1 Hz for 25–30 seconds.
