Filter by:Introduction: The loss of normal values of ROM due to the lack of flexibility and strength in the hip flexors, quadriceps and hamstrings in soccer players can cause a loss of mobility of the hip and knee joint. Proprioceptive neuromuscular facilitation is an active-assisted stretching technique used to improve flexibility and therefore the ranges of joint mobility. Aim. To assess the effectiveness of an intervention by proprioceptive neuromuscular facilitation in the improvement of flexibility and strength in the hamstring, hip flexor and quadriceps musculature compared to conventional stretches in football players. Study design. Randomized, multicentric, single-blind clinical study. Methods. The 30 players will be randomly assigned to the study groups: experimental (proprioceptive neuromuscular facilitation and static stretches) and control (static stretches). The treatment will last 6 weeks, with two sessions a week of 5 minutes each. The study variables will be the range of hip mobility (using goniometry), hamstring flexibility (using the EPR test, inclinometer) and the strength of hip flexors, quadriceps and hamstrings (through the RM test). A descriptive statistical analysis will be carried out calculating the main statistical characteristics and after calculating the normality of the sample (test Kolmogorov- Smirnov), the differences between evaluations in each group (t-student test) and the intra- and intersubject effect will be calculated (ANOVA of repeated measures). Expected results. Improved hip mobility, hamstring flexibility and strength in hip flexors, quadriceps and hamstrings muscles.
Introduction: In jumping sports the tendinopathies of patellar and Achilles tendon are very frequent. Sports performance is the action that optimizes the relationship between physical abilities and the exercise to be performed. Good proprioceptive work favors the correct execution of the technique in jumping sports. Aim: To evaluate the effectiveness of the lower limb proprioception exercise in the increase of sports performance, in adults and federated long jumpers Study design: Randomized single-blind multicenter study, with follow-up period. Methods: The 139 subjects included in the study will be randomly assigned to the two study groups: experimental (proprioception protocol) and control (non-intervention group). The intervention will be carried out for 4 weeks, with two weekly sessions, lasting 25 minutes. Three evaluations were carried out (baseline, post-intervention and follow-up). The study variables will be: Proprioception (evaluated by the Romberg test and the SEBT), and sports performance (evaluated with vertical, horizontal jump and competition simulation tests). The analysis of normality will be carried out by the Kolmogorov Smirnof test and in the case of homogeneity of the groups, through the t-student test of related measures and an ANOVA of repeated means, we will calculate the difference between the different evaluations and the effect intra and intersubject. Expected results. To observe improvement in sports performance, once the proprioceptive exercises have been carried out.
Introduction. The prevalence of ankle injuries in basketball are high. The lack of balance in the ankle is one of the main causes that produces these injuries. The goal of core training is to increase the physical capacities of resistance strength in the abdomen and analyze if it produces improvement in proprioception in the ankle joint in basketball players. Objective. To evaluate the effectiveness of Core training to improve the strength of the abdomen and analyze if it produces improvement in proprioception in ankle of basketball players. Study design. Randomized, multicentric, single-blind clinical study with a follow-up period. Methods. The 30 participants recruited will be randomly assigned to the two study groups: experimental (Core training for strength in the abdomen) and control (without intervention). The treatment will last 4 weeks, with 3 weekly sessions, approximately 20 minutes each. There will be three evaluations (pre-intervention, post-intervention and follow-up). On the dependent variables: strength core resistance (evaluated with Trunk Flexor Test, Trunk Extender Test, and Side Bridge Test) and proprioception (measured with the Star Excursion Balance tests and Romberg test) With the Kolmogorov Smirnov statistical test we will calculate the normality and with the t-student test of paired data and an ANOVA of repeated measures, we will obtain the difference between the three evaluations and the intra and intersubject effect, respectively. Expected results. To observe improvement in strength in the abdomen and analyze if it produces improvement in proprioception in the ankle of basketball players.
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 osteoarthritis (OA) is a chronic and degenerative disease which brings articular cartilage degeneration. As a consequence, balance and proprioception could be dangerously reduced after total knee arthroplasty. Several studies demonstrated the correlation between OA, proprioception reduction and increased risk of falling. The aim of this study is to evaluate the proprioception improvement in patients with total knee arthroplasty.

In healthy individuals, many postural musculoskeletal problems arise due to various reasons. The cervical region is the region where these problems are most common. The cervical region ranks second in the general population after the lumbal area of musculoskeletal system disorders and affects close to 70% of the general population.The most important causes of this posture disorder are; muscular performance and strength are inadequate, as well as decreased proprioception of the muscles, deterioration of the individual balance systems that result in individual visual or vestibular problems. Exercise therapy is at the forefront of these methods, while a variety of methods are applied in the prevention and treatment of neck problems. Recent studies have focused on multifaceted treatments including exercises to improve strength, endurance and coordination of cervical muscles, proprioceptive training, relaxation exercises to prevent muscle tension, stabilization exercises and behavior modification. Cervical stabilization exercises are a frequently used exercise approach. Cervical stabilization exercises, which are different from ordinary exercises, are based on biomechanics, neurophysiology and physiotherapy research. The main objective of this method is; improve body awareness, maintain posture uniformity, improve strength, endurance, coordination and proprioception. Stabilization exercises also increase the strength and endurance of the postural and stabilizer muscles, improving stability control in the stabilized and non-stabilized positions. Another method that contributes to the development of balance and proprioceptive sense is vibration application. Proprioception plays an important role in ensuring the coordination of movements. When the proprioception input is disturbed, both the position sense and the speed of movement may be affected. Muscle-tendon vibration is a noninvasive method that is often used in proprioception studies. It has been suggested that the vibration application are the enhancing effect of the proprioceptive. However, there is not enough research on this subject. The purpose of this study is to determine whether the cervical stabilization exercises to be applied to the cervical region and the local vibration applied to the neck muscles are related to muscle performance, proprioception and balance and their superiority with each other.
Persons with HIV can present vestibular system impairments, affecting postural stability. There is scarce literature related to the contribution of the visual and somatosensory systems in maintaining postural stability in persons with HIV. The purpose of this study is to describe the sensory systems used to maintain postural stability and how the sources of sensory information contributes to postural stability in asymptomatic persons with HIV. Postural stability was measured in 20 asymptomatic persons with HIV (11 male, 9 female, aged 43 ± 8 years). Static postural stability was evaluated during eight conditions that perturbed the visual, somatosensory and vestibular inputs. A paired-samples t-test was conducted to compare center of pressure (COP), antero-posterior displacement (APD) and right-left displacement (RLD) on stable and unstable surface and to characterize each balance sensory system. There was a significant difference in the COP and APD of eyes open condition compared to the remaining conditions on stable surface. Furthermore, there was a significant difference in the COP, APD and RLD for the eyes open on a foam surface compared to the remaining conditions on an unstable surface. Postural instability can be detected in asymptomatic persons with HIV under challenging conditions, previous to the evident appearance of balance impairments.
The aging population is at an exceptionally high risk of debilitating falls, contributing significantly to reduced independence and quality of life. It remains extremely challenging to screen for falls risk, and programs designed to mitigate falls risk have only modestly influenced the sizeable portion of the aging population experiencing one or more falls annually. Balance control in standing and walking depends on integrating reliable sensory feedback and on planning and executing appropriate motor responses. Walking balance control is especially dynamic, requiring active and coordinated adjustments in posture (i.e., trunk stabilization) and foot placement from step to step. Accordingly, using a custom, immersive virtual environment, the investigators have shown that sensory (i.e., optical flow) perturbations, especially when applied during walking, elicit strong and persistent motor responses to preserve balance. Exciting pilot data suggest that these motor responses are remarkably more prevalent in old age, presumably governed by an increased reliance on vision for balance control. Additional pilot data suggest that prolonged exposure to these perturbations may effectively condition successful balance control strategies. Founded on these recent discoveries, and leveraging the increase reliance on vision for balance control in old age, the investigators stand at the forefront of a potentially transformative new approach for more effectively identifying and mitigating age-related falls risk. The investigator's overarching hypothesis is that optical flow perturbations, particularly when applied during walking, can effectively identify balance deficits due to aging and falls history and can subsequently condition the neuromechanics of successful balance control via training.
