Active clinical trials for "Somatosensory Disorders"

The purpose of the study is to assess changes in health-related quality of life in patients undergoing surgical correction of pectus carinatum. In addition, the study assessed long-term effects of surgical intervention in relation to the development of persistent postoperative pain and / or sensory disturbances in the surgical field.

Cerebral Palsy (CP) is a non-progressive neurodevelopmental disorder characterized by posture and movement disorders as a result of damage to the immature brain for any reason before, during or after birth.In addition to tone, postural and neuromuscular control in children with Cerebral Palsy; Problems are also observed in communication skills, perceptual and cognitive systems and sensory systems.

Introduction Anterior knee pain (AKP) commonly affects physically active as well as sedentary individuals and the aetiology remains unknown. Altered joint position sense (JPS) impacts accurate motor action and knee joint stability. It is unclear whether people with AKP have altered JPS. The aim of this study was to investigate the JPS of individuals with AKP. Methods A descriptive cross-sectional design was used to measure JPS in twenty-five participants with unilateral or bilateral AKP. The Vicon 3D motion analysis system was used to assess JPS by means of active joint position sense testing during single leg squat and active knee extension in sitting. Target angles were self-determined based on each participant's capabilities. The absolute error (AE) was used as the main outcome measure. Impaired JPS was classified as an AE equal to or greater than five degrees.

Aims: Examine the effects of a community Tai Chi program on measures of balance and sensorimotor function. Methods: In a pre-test and post-test design, balance was measured in older adults (N=344; 73.4±7.4 years) with 30-second chair stand, timed-up and go, and 4-stage balance test following a 12-week community-based tai chi intervention. Balance measures and additional sensorimotor measures, including hip abductor electromechanical delay and hip proprioception, were measured in a smaller sample of older adults (n=11; 67.3±3.7 years).

The term proprioception was first introduced by Sherrington in 1906, who described it as a type of feedback from the limbs to the central nervous system. Based on the early descriptions by Sherrington and others, the contemporary terms of joint position sense (JPS), kinaesthesia (perception of active and passive motion), and sense of tension or force sense are considered sub modalities of proprioception. For the extremity joints, goniometers (universal, bubble, digital) can also be used to measure active JPS. Depending on the device used and the extremity joint measured, reliability and measurement error of active movement goniometry can range widely and this should be carefully considered if goniometry is used to measure active JPS of extremity joints. Kinesthesia, can be measured by calculating the passive motion detection threshold of individuals. The force sense (FS), commonly assessed using force reproduction, has also been used as a measure of proprioception. Assessing force reproduction by limb matching involves the use of a reference force, usually determined as a percentage of a Maximal Voluntary Isometric Contraction (MVIC), and attempting to replicate that force. Proprioception can be decreased in those who suffer from knee injury. Because patients with severe degenerative joint disease often require total knee arthroplasty to relieve pain, improve stability, and restore function. Due to problems such as oedema, immobilization and subjective pain after surgery, it is difficult to evaluate proprioception with joint repositioning method. In such cases, the assessment of FS could be of particular interest in the knee region. FS can also be measured by the accuracy of reproducing a specific target force. For example, the pressure biofeedback device (PBD) used for assessing the cranio-cervical flexion test could be considered a method of assessing force sense in the cervical spine. The ability to hold steadily or the accuracy in achieving and maintaining a desired pressure can be used. However, for the knee region, there is no method to measure the force sense via a device that can be used in clinical practice. The aim of this study was to establish a method for measuring FS that could be applied quickly and practically in the clinic, and to correlate the outcomes with surface electromyographic (EMG) muscle activation levels from M. Quadriceps femoris to demonstrate the applicability and objectivity of this method.

The goal of this observational study is to compare the validity and reliability of three Different methods used for wrist proprioception measurement in the healthy population. The main question[s] it aims to answer are: Are the methods valid and reliable? Which method is superior? Wrist proprioception measurement of the participants is performed. Researchers compared the inclinometer, goniometer, and joint position sense goniometer to determine the superior method.

To investigate long term affects of multiple concussions on the cognition, balance, proprioception, and biomarkers in retired National Hockey League players

This study aimed to evaluate the association between the isokinetic knee strength and/or proprioception performance with the functional performance on the functional Hop-tests and Y-balance test. This study included 20 healthy individuals who performed an isokinetic assessment of knee proprioception (joint position sense, JPS and threshold to detection of passive motion, TDPM) and flexors/extensors strength. At the same time, they performed a functional testing consisting of three Hop-tests (single, triple and cross-over) and the Lower Quarter Y-Balance Test (YBT-LQ). We tested the correlation between the isokinetic and functional performances, and limb symmetry indexes.

The investigators propose to explore the hypothesis that vibrotactile channels for indicating spatial orientation can be exploited as a sensory prosthesis. The specific research applications will be used for guiding visual orientation, to provide alternative feedback to vision and vestibular signals for controlling balance, and for directional and lateralisation cueing in patients with neglect syndromes. The programme will study whether vibrotactile feedback improves performance and also if it speeds rehabilitation when used as an adjunct to conventional therapy.

The loss of sensorial feedback causes gait impairment in hemiparesis. The studies show that proprioceptive impairment of knee is related to falling in these patients. The aim of this study is to investigate the effects of proprioception on balance and gait functions in hemiparetic individuals.
