We aimed to investigate the local anesthetic effect of 2-adamantanamine in spinal anesthesia. The dose-response curves were constructed after intrathecally injecting the rats with five doses of 2-adamantanamine and a common local anesthetic mepivacaine. The quality and duration of 2-adamantanamine at producing spinal nociceptive, proprioceptive and motor block were compared with that of mepivacaine. We revealed that 2-adamantanamine provoked spinal nociceptive, proprioceptive and motor block dose-dependently...

It has been recently shown in rats that spontaneous movements of whisker pad macrovibrissae elicited evoked responses in the trigeminal mesencephalic nucleus (Me5). In the present study, electrophysiological and neuroanatomical experiments were performed in anesthetized rats to evaluate whether, besides the whisker displacement per se, the Me5 neurons are also involved in encoding the kinematic properties of macrovibrissae movements, and also whether, as reported for the trigeminal ganglion, even within the Me5 nucleus exists a neuroanatomical representation of the whisker pad macrovibrissae...

The neuregulin-1 (NRG1) signaling pathway plays an important role in the development of the peripheral neuromuscular system, including in muscle spindle and postnatal myelination. We previously showed that NRG1 on the axonal membrane regulates peripheral nerve myelination through Grb2-associated binder 1 (Gab1), a scaffolding mediator of receptor tyrosine kinase signaling. Here, we determined the role of Gab1 in the development of muscles and the muscle spindle using muscle-specific conditional Gab1 knockout mice...

Bell's palsy (BP) in children is a rare case with no documented evidence regarding its rehabilitation management. Till date, individuals with BP are being treated with electrical stimulation are proportionately greater than other conventional means such as facial exercise and massage. These conventional modes of treatment have proved to have less incidence of synkinesis with more benefits. Here, we report a case of a 7-year-old boy diagnosed clinically to have right idiopathic facial nerve paralysis, who underwent 14 days of facial proprioceptive neuromuscular facilitation exercises along with facial therapeutic massage...

LLow ankle sprains are common injuries in young athletes. Hence, it is imperative that low ankle sprains are diagnosed and treated quickly and effectively. We reviewed the: (1) anatomy; (2) imaging; (3) physical exam findings; and (4) treatment modalities regarding these injuries. Plain radiographs are standard of care and routine MRI is not recommended for suspected sprains. However, physical exam findings often may guide management decisions. The majority of patients diagnosed with low ankle sprains are treated with a one- to two-week immobilization period with physical therapy focused on peroneal proprioception and strength...

Hypermobility may be associated with decreased lower extremity proprioception, which in turn may increase injury risk. The prevalence of hypermobility in dancers varies across studies, but joint hypermobility appears to be more common in dancers than in the general population. The purpose of this study was to determine how hypermobility affects eyes-closed single-limb balance as an indirect measure of proprioception in dancers. The secondary aim was to compare hypermobility and balance across dancer affiliation groups...

PATIENT: This report describes the case of a 68 year old female patient who presented with the chief complaint of difficulty in chewing and poor aesthetics due to missing teeth. The patient was interested in saving the remaining natural teeth and desired minimal tissue coverage from the prosthesis. After consideration of all the factors involved, it was deemed advisable to resort to a palate free maxillary telescopic complete denture and a mandibular removable partial denture. DISCUSSION: Considering the age of the patient and the cost involved, implant supported prosthesis was ruled out as a treatment option for the patient...

BACKGROUND: Kinesthesia (sense of limb movement) has been extremely difficult to measure objectively, especially in individuals who have survived a stroke. The development of valid and reliable measurements for proprioception is important to developing a better understanding of proprioceptive impairments after stroke and their impact on the ability to perform daily activities. We recently developed a robotic task to evaluate kinesthetic deficits after stroke and found that the majority (~60%) of stroke survivors exhibit significant deficits in kinesthesia within the first 10 days post-stroke...

A classic problem in psychology is understanding how the brain creates a stable and accurate representation of space for perception and action despite a constantly moving eye. Two mechanisms have been proposed to solve this problem: Herman von Helmholtz's idea that the brain uses a corollary discharge of the motor command that moves the eye to adjust the visual representation, and Sir Charles Sherrington's idea that the brain measures eye position to calculate a spatial representation. Here, we discuss the cognitive, neuropsychological, and physiological mechanisms that support each of these ideas...

There has been compelling evidence favoring the idea that human adults similarly represent number and time along a horizontal mental number line (MNL) and mental time line (MTL), respectively. Yet, analogies drawn between the MNL and MTL have been challenged by recent studies suggesting that adults' representations of number and time arise from different spatial frames of reference; whereas the MNL relies on both hand-centered and object-centered coordinates, the MTL appears to be exclusively anchored on object-centered coordinates...

A network of myelinated nerve fibers in the peritoneum covers the abdominal wall. We studied the topographic distribution of this network, explored the fibers' destination in the central nervous system, and examined the markers in these fibers in order to identify the nature of the sensation conveyed by the network of nerve fibers in rats. We used Sihler's method, which stains myelinated fibers in whole mount materials, and observed a dense nerve network and endings toward the peritoneal cavity in the peritoneum that covers the abdomen's lateral bulge...

PURPOSE/BACKGROUND: Shoulder proprioception is essential in the activities of daily living as well as in sports. Acute muscle fatigue is believed to cause a deterioration of proprioception, increasing the risk of injury. The purpose of this study was to evaluate if fatigue of the shoulder external rotators during eccentric versus concentric activity affects shoulder joint proprioception as determined by active reproduction of position. STUDY DESIGN: Quasi-experimental trial...

The paradigm of the rubber hand illusion was applied to a shadow to determine whether the body-shadow is a good candidate for the alternative belonging to our body. Three kinds of shadows, a physical hand, a hand-shaped cloth, and a rectangle cloth, were tested for this purpose. The questionnaire results showed that both anatomical similarity and visuo-proprioception correlation were effective in enhancing illusory ownership of the shadow. According to the proprioceptive drift measurement, whether the shadow purely originated from the physical body was a critical factor in yielding the significantly positive drift...

Somatoparaphrenic symptoms after left-hemisphere damage are rare. To verify the potential role of body-related sensory (proprioceptive, visual, and somatosensory) manipulation in patients experiencing sensations of hand disownership, the symptoms of a patient suffering from right-hand somatoparaphrenia were monitored and clinical and neuropsychological variables were controlled. Four types of manipulation were administered: changes in spatial position of the hand, multisensory stimulation, and self-observation using video or mirrors...

The coracoacromial ligament (CAL) was first described as a pain generator by Dr Charles Neer in the early 1970s. Since that time, considerable controversy regarding CAL management during acromioplasty has persisted. This review aims to better understand the role of the CAL in shoulder physiology and pathology. Sixty-six articles from 1958 to 2016 were identified using an electronic search of PubMed, Cochrane Library, AccessMedicine, and MD Consult for case series as well as cohort and prospective studies. The authors used "coracoacromial ligament" and "coracoacromial veil" as medical subject headings (MeSH)...
