ABSTRACT:
7
Objective:
8
To determine whether dry needling of an active myofascial trigger point (MTrP) reduces pain
9
and alters the status of the trigger point to either a non-spontaneously tender nodule or its
RI PT
6
resolution.
11
Design:
12
A prospective, non-randomized, controlled interventional clinical study
13
Setting:
14
University campus
15
Participants
16
Fifty-six subjects with neck or shoulder girdle pain > 3 months duration and active MTrPs were
17
recruited from a campus-wide, volunteer sample. Fifty-two completed the study (23 male/33
18
female) with mean age of 35.8 years.
19
Interventions
20
Three weekly dry needling treatments of a single active MTrP
21
Main Outcome Measures
22
Primary Outcomes: Baseline and post treatment evaluations of pain using the verbal analogue
23
scale, the Brief Pain Inventory and the status of the MTrP as determined by digital palpation.
24
Trigger points were rated: active (spontaneously painful), latent (requiring palpation to reproduce
25
the characteristic pain) and resolved (no palpable nodule).
26
Secondary Outcomes: Profile of Mood States, Oswestry Disability Index, Short Form 36,
27
Cervical Range of Motion.

Primary outcomes: 41 subjects had a change in trigger point status from active to latent or

resolved; and 11 had no change (p < .001). Reduction in all pain scores was significant (p
