The application of dry needling usually is associated with
postneedling-induced pain.
A postneedling intervention to reduce this adverse
event is needed. OBJECTIVE: To determine the effectiveness of low-load exercise
on reducing postneedling-induced pain after dry needling of active trigger points
(TrPs) in the infraspinatus muscle in subacromial pain syndrome. DESIGN: A
72-hour follow-up, single-blind randomized controlled trial. SETTING: Urban
hospitals. PARTICIPANTS: Individuals with subacromial pain syndrome (n = 90, 52%
female, mean age: 35 +/- 13 years) with active TrPs in the infraspinatus muscle.
INTERVENTIONS: All individuals received dry needling into the infraspinatus
active TrP. Then, they were divided randomly into an experimental group, which
received a single bout of low-load exercise of shoulder muscles; a placebo group,
which received inactive ultrasound for 10 minutes; and a control group, which did
not receive any intervention. OUTCOME MEASURES: Numerical Pain Rating Scale (0-10
point) was administered postneedling, immediately postintervention (2 minutes),
and 24, 48, and 72 hours after needling. Shoulder pain (Numerical Pain Rating
Scale, 0-10) and disability (Disabilities of the Arm, Shoulder and Hand; Shoulder
Pain and Disability Index) were assessed before and 72 hour after needling.
RESULTS: The 5 x 3 analysis of covariance showed that the exercise group
demonstrated a larger decrease in postneedling-induced pain immediately after (P
= .001), 24 hours (P = .001), and 48 hours after (P = .006) than placebo or
control groups. No differences were found at 72 hours (P = .03). Similar
improvements in shoulder pain (P < .001) and related disability (Disabilities of
the Arm, Shoulder and Hand: P < .001; Shoulder Pain and Disability Index: P <
.001) were observed 72 hours after needling, irrespective of the treatment group.
CONCLUSIONS: Low-load exercise was effective for reducing postneedling-induced
pain on active TrPs in the infraspinatus muscle 24 and 48 hours after needling.
The application of a postneedling intervention did not influence short-term pain
and disability changes. LEVEL OF EVIDENCE: I.
