OBJECTIVE:
The purpose of this study was to investigate the immediate effect of electric point stimulation in treating latent upper trapezius trigger points compared to placebo.
DESIGN:
Double blind randomised placebo-controlled trial.
SETTING:
Anglo-European College of Chiropractic.
PARTICIPANTS:
Sixty participants with latent upper trapezius trigger points.
INTERVENTIONS:
Electric point stimulator type of TENS, or detuned (inactive) electric point stimulator type of TENS.
MAIN OUTCOME MEASURES:
The three outcome measures were pressure pain threshold at the trigger point, a numerical rating scale for pain elicited over the trigger point, and lateral cervical flexion to the side opposite the trigger point.
RESULTS:
On the outcome of pressure pain threshold the electric point stimulator group had a mean change of 0.49 (0.99) kg/cm(2), while the placebo group had a mean change of 0.45 (0.98) kg/cm(2) (t = 0.16, df = 58, p = 0.88). For change in pain over the trigger point, the electric point stimulator group had a mean decrease of 0.93 (0.87) points, while the placebo group had a mean decrease of 0.23 (0.97) points (t = 0.70, df = 58, p = 0.005). On the outcome of change in lateral cervical flexion the electric point stimulator group had a mean increase of 2.87 (4.55) degrees, while the placebo group had a mean increase of 1.99 (2.49) degrees (t = 0.92, df = 58, p = 0.36).
CONCLUSION:
Electric point stimulator type of TENS is superior to placebo only in reduction of pain for treating latent upper trapezius trigger points.
