Dry needling has the advantage of providing an
objective criterion of effectiveness. When the needle reaches the
locus of the trigger point, an
involuntary muscle contraction (local twitch response, LTR) occurs, typically several contractions per single insertion.
The practitioner holds the trigger point with a
pincer or flat grip and performs
linear movements of the needle within the trigger point. There are
two main techniques:
- “Sewing machine” technique – the needle remains in the subcutaneous fat layer and moves along with it.
- Conical insertion technique – the angle of needle insertion is altered during the procedure.
Typically,
10–12 insertions are performed per session. This can be complemented with a
hot moist compress (moist heat pad).
Trigger point injections (injecting a drug into the trigger point) are
not required to treat the trigger itself; they are used
only for pain relief. However, injections carry a
higher risk of complications and side effects, such as accidental injection into a vessel or nerve
