Abstract Hakkinen A, Ylinen J, Rinta-Keturi M, Talvitie U, Kautiainen H, Rissanen A. Decreased neck muscle strength is highly associated with pain in cervical dystonia patients treated with botulinum toxin injections. Arch Phys Med Rehabil 2004;85:1684–8. Objectives To compare the isometric neck muscle strength of cervical dystonia patients treated with botulinum toxin injections with that of healthy control subjects and to evaluate the association between neck strength, neck pain, and disability in these patients. Design Clinical cross-sectional study. Setting Outpatient rehabilitation and neurology clinics in a Finnish hospital. Participants Twenty-three patients with cervical dystonia wi…

ASYMMETRY OF SELECTIVE ATTENTION IN HEALTHY SUBJECTS AND PATIENTS WITH CERVICAL FOCAL DYSTONIA

The environment continuously provides a wealth of information through our senses. This poses a major challenge to our brains to effectively process the relevant pieces of information over space and time, involving attentional processes. Attention selects, modulates and sustains focus on information most relevant for behaviour going beyond our limited capacity to process competing options. Voluntary allocation of attention to features, objects, or regions in space is controlled by top-down mechanisms. On the other hand, salient stimuli can automatically attract attention, even though the subject does not have intentions to attend to these stimuli. A key question is how attention is shaped by…

Reduced Neck Muscle Strength and Altered Muscle Mechanical Properties in Cervical Dystonia Following Botulinum Neurotoxin Injections : A Prospective …

2016

Cervical dystonia (CD) is a focal dystonia causing involuntary activation of neck and shoulder muscles resulting in abnormal, sustained and painful posturing that may lead to physical disability and social withdrawal [1]. In recent years, botulinum neurotoxin (BoNT) has become the first line therapy for CD [2]. A subjective feeling of neck weakness has been reported as one of the most common localized adverse events of BoNT [2-7]. In clinical practice, this may sometimes be reported as having difficulty keeping the head upright. Although the effects of BoNT have been widely studied [2,5], there have been no prospective studies quantifying changes in maximal isometric neck muscle strength. O…
