This study was designed to investigate the effects of injection with a local anesthetic agent or dry needling into a myofascial trigger point (TrP) of the upper trapezius muscle in 58 patients. Trigger point injections with 0.5% lidocaine were given to 26 patients (Group I), and dry needling was performed on TrPs in 15 patients (Group II). Local twitch responses (LTRs) were elicited during multiple needle insertions in both Groups I and II. In another 17 patients, no LTR was elicited during TrP… 
Comparison of lidocaine injection, botulinum toxin injection, and dry needling to trigger points in myofascial pain syndrome
TLDR
Injection is more practical and rapid, since it causes less disturbance than dry needling and is more cost effective than BTX-A injection, and seems the treatment of choice in MPS.
Different Substances and Dry-Needling Injections in Patients with Myofascial Pain and Headaches
TLDR
Levels of pain intensity, frequency and duration, local post-injection sensitivity, obtainment time and duration of relief, and the use of rescue medication were evaluated and all three groups showed favorable results for the evaluated requisites.
Botulinum Toxin, Lidocaine, and Dry-Needling Injections in Patients with Myofascial Pain and Headaches
TLDR
Considering its reduced cost, lidocaine could be adopted as a substance of choice, and botulinum toxin should be reserved for refractory cases, in which the expected effects could not be achieved, and the use of a more expensive therapy would be mandatory.
The effect of dry needling on the active trigger point of upper trapezius muscle: Eliciting local twitch response on long-term clinical outcomes.
TLDR
DN without elicit LTR has superiority over the DN along with eliciting LTR while the treatment aimed to receive long-term effects, and there was no significant difference between groups according to the disability.
Paraspinal Stimulation Combined With Trigger Point Needling and Needle Rotation for the Treatment of Myofascial Pain: A Randomized Sham-controlled Clinical Trial
TLDR
This study highlighted the greater efficacy of MDIMST over the placebo-sham and LTrP-I and indicated that both active treatments are more effective than placebo- sham for MPS associated with limitations in active and routine activities.

TLDR
Trigger point injection is a valuable procedure for pain relief for patients in both group and patients with FMS are likely to experience significant but delayed and attenuated pain relief following injection of their active TrPs compared to myofascial pain patients with similar TrPs but without FMS.
Acupuncture Needling versus Lidocaine Injection of Trigger Points in Myofascial Pain Syndrome in Elderly Patients – a Randomised Trial
TLDR
Both groups improved, but there was no significant difference in reduction of pain in the two groups at any time point up to one month, and the range of cervical movement improved in both groups, apart from extension in the acupuncture needling group.
Effects of Trigger Point Dry Needling on Neuromuscular Performance and Pain of Individuals Affected by Patellofemoral Pain: A Randomized Controlled Trial
TLDR
TrP-DN at the quadriceps combined with stretch can reduce the pain, and improves the clinical symptoms and function, the VMO/VL ratio, and the coordination of VMO and VL in patients with PFPS.
Immediate Effects of Dry Needling and Myofascial Release on Local and Widespread Pressure Pain Threshold in Individuals With Active Upper Trapezius Trigger Points: A Randomized Clinical Trial.
TLDR
A single application of DN or MR generated local and distant hypalgesic responses superior to placebo and future trials are needed to examine whether these findings occur in long-term follow-ups.
Effects of dry needling of active trigger points in the scalene muscles in individuals with mechanical neck pain: a randomized clinical trial
TLDR
This trial suggests that a single session of DN over active TrPs in the scalene muscles could be effective at reducing pain and increasing inspiratory vital capacity in individuals with mechanical neck pain.
