The study was performed to investigate the relationship between perceived muscle tension and electromyographic hyperactivity and to what extent electromyographic (EMG) hyperactivity relates to personality traits in ébromyalgics. Thirty-six females with é bromyalgia performed isokinetic maximal forward è exions of the shoulder combined with surface EMG recordings of the trapezius and infraspinatus muscles. Signal amplitude ratio and peak torque were calculated in the initial and endurance test phases. Pain intensity, perceived general and local shoulder muscle tension, and personality traits using the Karolinska Scales of Personality were assessed pre-test. Neither perceived muscle tension nor muscular tension personality trait correlated with EMG muscle hyperactivity. Perceived general muscle tension correlated with aspects of anxiety proneness (including muscle tension) of the Karolinska Scales of Personality. Pain intensity interacted with many of the variables. We propose that when patients with é bro- myalgia report muscle tension that they may be expressing something other than physiological muscle tension.

    • ...Although some previously published studies have related FM and s-EMG [17,18], they provide no information concerning changes in the myoelectrical manifestations of fatigue as a marker of muscle functional reorganisation in FM. The aims of this non-invasive EMG-based (s-EMG) study of fibromyalgic patients and a matched control group were to assess whether FM muscle is different in terms of the development of muscle fatigue (i.e...
