Randomized Controlled Trial Clinical Trial
The role of sensory and motor evoked potentials in the prognosis of Pott's paraplegia.
In view of paucity of evoked potential changes in Pott's paraplegia, it is proposed to evaluate the role of motor and somatosensory evoked potentials in predicting the outcome. ⋯ MEP and SEP both are helpful in predicting 6-month outcome. Combining SEP and MEP gives stronger correlation with 6-month outcome compared to only MEP or SEP. The potential role of evoked potentials in deciding different therapeutic strategies needs further studies.

Randomized Controlled Trial Clinical Trial
Glutamate evoked neck and jaw muscle pain facilitate the human jaw stretch reflex.
Although pain and neuromuscular function are clearly linked in several clinical conditions manifested in the craniofacial and cervical regions, it is unclear if pain in these regions influences reflexly evoked activity in the jaw or neck muscles in humans. The aim of the present study was to test the effects of glutamate-evoked jaw or neck muscle pain on the jaw stretch reflex recorded in both jaw and neck muscles. ⋯ The changes in neuromuscular activity documented in this study may be involved in the clinical occurrence of altered muscle activity in the orofacial and cervical regions as a result of deep tissue trauma and pain.

Randomized Controlled Trial Clinical Trial
Simultaneous modulation of the exteroceptive suppression periods in the trapezius and temporalis muscles by experimental muscle pain.
To investigate whether the exteroceptive suppression (ES) periods in the trapezius and temporalis muscles could be simultaneously modulated by either experimental trapezius muscle pain or temporalis muscle pain. ⋯ The findings of the present study provide evidence for a bi-directional effects reflecting convergence of muscle afferents from the trigeminal and upper cervical neural systems in humans, which may partly underlie the manifestations of pain referral between these two areas.

Randomized Controlled Trial Comparative Study Clinical Trial
Effects of TMJ anesthesia and jaw gape on jaw-stretch reflexes in humans.
To study the roles of afferent sensory inputs in the temporomandibular joint (TMJ) and of muscle length in the modulation of the jaw-stretch reflex in humans. ⋯ Blocking the afferent sensory input (including the mechanoreceptors) from the TMJ seems to have no influence on the sensitivity of the human jaw-stretch reflex. Instead, muscle spindles are the most likely receptors to be responsible for the reflex modulation that was observed in the present study.

CAP variables and arousals as sleep electroencephalogram markers for primary insomnia.
Polysomnographic (PSG) measures consistently reflect poor sleep quality and effective treatment in insomniac patients. ⋯ PSG investigation extended to CAP variables and EEG arousals can be an important procedure for the diagnosis of primary insomnia and evaluation of treatment efficacy.
