Trigger points are the tight fibrous areas of muscle, which can impact on the muscles performance and often cause pain locally as well as referred pain.
Needles are single use and inserted into the muscle fibre where the trigger point has been located by the therapist. The practitioner may move the needle to find the trigger point and usually a referred pain is felt by the client followed by a local twitch response. This is the way the muscle releases. After 2-3 twitch responses are felt, the needle is taken out. Gentle stretching helps to relieve any residual pain.
