Abstract
Results Compared to controls TTH patients had a significantly weaker neck extension (21.49±10.31Nm) vs. (17.07±9.16 Nm) (p= 0.02) resulting in a significantly lower Extension/ Flexion moment ratio (p=0.03). TTH-patients also showed a tendency to significantly lower shoulder abduction strength (44.3±19.3 Nm) vs. (38.7, ±15.9 Nm.) (p = 0.05). Conclusions The reduced neck Extension/Flexion ratio due to decreased strength of the neck extensors and the borderline lower shoulder abduction strength, suggests an unbalanced muscle activity in TTH patients. No conflict of interest.
Highlights
Tension-type headache (TTH) is associated with increased muscle tenderness, with an increasing headache frequency and intensity
The potential role of the peripheral muscles in TTH is unclear, and it is unknown if tenderness is related to strength
The Maximal Voluntary Isometric Contraction (MVC) in neck extensor and flexor muscles were tested with the subject seated upright
Summary
