dc.description.abstract | Background: fibromyalgia is a relatively common condition with widespread pain and pressure allodynia, but
unknown aetiology. For decades, the association between motor control strategies and chronic pain has been a
topic for debate. One long held functional neuromuscular control mechanism is differential activation between
regions within a single muscle. The aim of this study was to investigate differences in neuromuscular control, i.e.
differential activation, between myalgic trapezius in fibromyalgia patients and healthy controls.
Methods: 27 fibromyalgia patients and 30 healthy controls performed 3 minutes bilateral shoulder elevations with
different loads (0-4 Kg) with a high-density surface electromyographical (EMG) grid placed above the upper
trapezius. Differential activation was quantified by the power spectral median frequency of the difference in EMG
amplitude between the cranial and caudal parts of the upper trapezius. The average duration of the differential
activation was described by the inverse of the median frequency of the differential activations.
Results: the median frequency of the differential activations was significantly lower, and the average duration of
the differential activations significantly longer in fibromyalgia compared with controls at the two lowest load levels
(0-1 Kg) (p < 0.04), but not at the two highest load levels (2 and 4 Kg).
Conclusion: these findings illustrate a different neuromuscular control between fibromyalgia patients and healthy
controls during a low load functional task, either sustaining or resulting from the chronic painful condition. The
findings may have clinical relevance for rehabilitation strategies for fibromyalgia. | nb_NO |
