Active clinical trials for "Somatosensory Disorders"

Tension-type headache is a headache that starts from the cervical and suboccipital regions, spreads from the back of the head to the parietal, frontal and temporal regions, and is felt in the form of compression, pressure and heaviness. Increased muscle and fascia tone in the cervical and cranial region, together with active trigger points and factors that trigger pain, cause tension-type headache. Head and neck fascia serves as an important proprioceptive structure in our body. Abnormal inputs from mechanoreceptors and structures around the joint cause deterioration in joint position sense. This study was planned to investigate the effects of the new facial distortion model on pain intensity, cervical posture and joint position sense, unlike the manual techniques used in previous studies in tension-type headache.

To determine the combined effects of proprioceptive neuromuscular facilitation and electrical muscle stimulation on spasticity and hand function in stroke patients.

This project assesses the feasibility, reliability, and validity of the PROMT in children with a UMN lesion. The study questions are: is the newly developed PROMT a feasible, reliable, and valid tool to assess lower limb proprioception in children with UMN lesions? Does the PROMT differ between children with UMN lesion and controlled neurotypically developing peers? Further, does the proprioception modalities assessed with the PROMT correlate with motor function in this group of children?

Supplementing or augmenting sensory information to those who have lost proprioception after stroke could help improve functional control of the arm. Thirty subjects will be recruited to a single site to evaluate the ability of supplemental kinesthetic feedback (a form of vibrotactile stimulation) to improve motor function. Participants will be tested in performing reaching movements as well as more functional tasks such as simulated drinking from a glass

With the change in lifestyle, most physical tasks are now performed by machines. As a result, sitting has become the most common learning posture and office posture, and cervical and lumbar spondylosis are becoming increasingly prevalent in younger people. One-third of life is devoted to sleep, and bad sleeping posture can place incorrect strain on the cervical and lumbar spine, resulting in irreversible and detrimental repercussions if not treated seriously. Sleep disorders have become an important public health concern because they can have detrimental effects on both mental and physical health. A pillow can give adequate support for the head and neck and assist sleepers in maintaining proper neck and thoracic curvature. Studies have demonstrated that a comfortable sleeping pillow helps relax the neck muscles, hence facilitating sleep, and efficiently alleviate pain in the neck, shoulders, back, and head. There is consensus among researchers that supporting the natural lordotic curve of the cervical spine is necessary to achieve longer periods of deep sleep. In addition, a pillow can improve sleep quality by cooling the head, lowering body temperature, reducing sweating or slowing the heart rate during sleep. However, the level of evidence to support these claims is so far limited. It has been claimed by pillow manufacturers that many design-related pillow parameters are effective in improving sleep quality and reducing neck pain. However, most of these recommendations are based on personal experience. This study recommends the most suitable pillow for people in forward head postures based on the body pressure distribution of the head, neck and upper body. The proposed pillows were evaluated in two parameters: comfort and support.

This clinical study evaluates the acute effect of glycerol ingestion on performance (power output), weight, urine specific gravity, biochemical (antioxidants and lactate) and metabolic (indirect calorimetry) markers in international athletes in hot conditions. The investigators hypothesized that acute glycerol ingestion can prevent performance loss (power generated at submaximal intensity) in hot conditions. To justify this hypothesis, the investigators will measure the aforementioned markers, which could establish a cause-effect relationship between acute glycerol intake and decreased performance loss in hot conditions.

The purpose of this study is to investigate the acute effects of foam rolling on elbow joint sensorimotor function with healthy participants . Study group will receive foam rolling exercise. Control group will receive no foam rolling exercise. Control group will be given a brochure including information about proprioception and foam rolling.

Both taping and balance exercises have effects on dynamic balance, so this study compared ankle taping and balance exercise on postural stability indices in healthy women. we hypothesized that both balance exercise and taping would increase stability indices but the effects of balance exercise was more greater than taping.

The purpose of this study is to investigate the long-term effects of foam rolling on elbow proprioception, strength and functional motor performance with healthy participants . Study group will receive foam rolling exercise. Control group will receive no foam rolling exercise. Control group will be given a brochure including information about proprioception and foam rolling.

Our sense of touch is essential to explore our environment and experience life and is based on signals from receptors in the body that are sensitive to different types of stimulation. The TACTHUM projects aims to investigate the fundamental firing of mechanoreceptors in the body to various external stimuli, with an end-aim to better understand the human somatosensory system and to apply this knowledge to provide comprehensive sensory feedback in prosthetics. We have a vast system of peripheral receptors in the skin and muscles that provide us with exquisitely detailed information about our everyday interactions. When there is injury to a body part, such as in amputation, there is a significant loss of somatosensory input. Prosthetic devices have greatly developmed in the past few years, especially with the introduction of useful sensory feedback. However, there is a lot to discover both about the workings of the somatosensory system and how to recreate this to give feedback in a prosthetic device. The main objective of the TACTHUM project is to understand how to recover and apply useful somatosensory feedback in prostheses for amputees. There are a number of other sub-objectives, to: Determine how tactile mechanoreceptors encode the texture of natural surfaces during passive and active exploration. Investigate how our sense of touch varies with emotional state. Explore what happens to our sense of touch when we explore surfaces at different temperatures. Understand the origin of our perception of humidity. Investigate differences in the encoding of tactile information with age. Determine the perceptions generated by the stimulation of single tactile afferents. Study changes in spontaneous activity and responses to tactile stimulation on the residual limb of amputees. To accomplish these objectives, we will primarily use the technique of microneurography, in vivo recordings from peripheral nerves, to gain direct information about the firing of peripheral neurons in humans. In conjunction with this, we will use a variety of mechanical and thermal stimuli to excite somatosensory fibers and register the activity of other physiological and perceptual measures. This will allow us to gain a fuller understanding of how the incoming somatosensory signals are interpreted and processed. Overall, we aim to explore how more naturalistic tactile interactions are encoded and how these can be translated to provide realistic prosthetic feedback.
