Background: Cervical dystonia (CD) involves clinical and motor manifestations, and visual and cognitive dysfunctions may also be frequent.
Objective: To evaluate functional vision, visual attention, and cognitive aspects in patients with CD compared with a control group.
Methods: Fifty patients with CD were assessed using the Useful Field of View Test (UFOV), the Mini Mental State Examination (MMSE), and the Trail Making Tests (TMT-A and TMT-B), and compared with an identical number of health controls matched by sex, age, and educational level.
Results: No differences were seen between the groups in terms of MMSE score ( = 0.481), but the CD patient group had poorer scores for the TMA-A ( = 0.004) and TMT-B ( = 0.004). For the UFOV subtests, a decrease was found for visual processing speed ( < 0.001), divided attention ( < 0.001), and selective attention ( = 0.001), as well as higher frequency in the categories with higher risk index in the UFOV test ( < 0.001).
Conclusion: Patients with CD may exhibit decreased functional vision and visual attention, as well as higher risk in performing complex activities.

Background: Medically refractory hypertonia (MRH) within the pediatric population causes severe disability and is difficult to treat. Neurosurgery for mixed MRH includes intrathecal baclofen (ITB) and lumbosacral ventral-dorsal rhizotomy (VDR). Surgical efficacy limitations can be mitigated by combining the two into a multimodal strategy.

Repetitive intramuscular injections of botulinum neurotoxin (BoNT) have become the treatment of choice for a variety of disease entities. But with the onset of BoNT therapy, the natural course of a disease is obscured. Nevertheless, the present study tries to analyze patients' "suspected" course of disease severity under the assumption that no BoNT therapy had been performed and compares that with the "experienced" improvement during BoNT treatment.

Background: Botulinum toxin is an attenuated neurotoxin of Clostridium Botulinum gram positive bacterial, which is used in medication sialorrhea, cervical dystonia, hyperhidrosis and non-surgical cosmetic operation (aesthetic) such as facial wrinkles and reduced the bulky appearance hypertrophied of masseter muscle. This study was designed to revealed the effect of zygomiticus inoculation of botulinum toxin B in zygomatic muscle of rats on zygomatic bone.
Methods: A total of 25 male albino rats (200-260 gm) were injected facial intramuscular by a single dose of 2.

Introduction: Cervical dystonia (CD) is characterized by involuntary neck muscle spasms that lead to abnormal head movements or postures. It is associated with somatosensory (tactile and proprioceptive) dysfunction. Here we tested whether vibro-tactile stimulation (VTS) of the cervical muscles constitutes a non-invasive form of neuromodulation of the somatosensory system that can provide temporary symptom relief for people with CD.

Background: Sprengel deformity is a rare congenital malformation of the scapula defined by malposition during embryonic development. Affected individuals have limited range of motion of the shoulder and torticollis. Surgical reconstruction is an option to treat patients with severe deformity and functional impairment.
