What effect did the twitch response have on pain change in patients undergoing dry needling?

The twitch response during dry needling is a fundamental aspect of the treatment’s efficacy. When the needle is inserted into a myofascial trigger point, it can elicit a local twitch response, which is an involuntary contraction of the muscle fibers. This twitch response indicates a release of tension and can be associated with several physiological changes in the muscle tissue.

The significance of the twitch response lies in its ability to affect pain perception in patients. Research indicates that when a twitch response occurs, it contributes to a greater change in pain levels, often resulting in reduced pain intensity following treatment. The mechanism behind this is believed to involve the modulation of nociceptive pathways and an increase in local blood flow, which can help facilitate healing and reduce muscle tightness.

Furthermore, the mechanical action of the needle and the subsequent twitch response may help interrupt the cycle of pain and dysfunction, leading to improved muscle function and pain relief. This outcome aligns with clinical observations that patients reporting a noticeable twitch response during sessions tend to experience more substantial pain relief compared to those who do not elicit this response.

While other options, like increased pain severity or reduced muscle stiffness, touch upon symptoms related to dry needling, they do not reflect the beneficial outcomes associated with the twitch response
