Filter by:Swallowing; It is a complex, dynamic, sensorimotor process involving more than 30 muscles located bilaterally in the oral, pharyngeal, and esophageal regions and involving the safe delivery of the food taken from the mouth to the stomach as a result of sequential and coordinated movements. The cervical region is important in terms of swallowing function, as it acts as a bridge between the oral and esophageal structures through the pharynx, hosts the larynx and upper respiratory tract, which plays an important role in safe swallowing, and contributes to the stabilization and preservation of posture thanks to the muscles in its structure. Craniocervical flexion (CCF) occurs at the atlantooccipital joint and upper cervical segments such as C1-2. While superficial muscles such as the SCM and anterior scalene muscles contract in cervical flexion, deep muscles such as the longus colli and capitis, which are mainly primary cervical stabilizer muscles, are activated in CCF. CCF is a movement felt as flexion in the upper part of the cervical region with a slight retraction of the chin. It is also known that the suprahyoid muscles are activated in CCF. Swallowing in the CCF posture has been shown to occur with less suprahyoid muscle activation. The cervical region must provide proper alignment, posture, and stabilization for effective and safe swallowing. Postural changes in the cervical region, and changes in the position of the hyoid bone cause changes in gravity, oropharyngeal structures, and muscle length-tension relationship, thereby changing the dynamics of swallowing function. Therefore, it is not possible to consider the cervical region separately from the swallowing function. However, the focus of the exercises to be chosen for the cervical region is different and the effects that are likely to occur may also be different. There is no study in the literature on the activation of superficial and deep muscles activated during swallowing of craniocervical flexion training exercises, which aim to improve cervical region mechanics by focusing especially on deep cervical flexors. The aim of this study is to investigate the effect of craniocervical flexion training (CCF) on swallowing-related structures in healthy individuals.
This is a study for evaluation of posture of patients with neurological disease in rehabilitation department.
Current balance and stability interventions have been shown to improve balance through targeting balance impairments and retraining effects. However, there are key facilitators and barriers 'that older adults may face to participate in such interventions'. Additionally, physical activity interventions fail to integrate older adults into the co-design and co-production of PA interventions. The study will aim to identify the impact and practicalities of an exercise intervention in older adults by performing pre selected exercises with an elastic resistance band attached at the hip and chest region to challenge balance. Static posturography will assess the impacts of the exercise intervention on balance and stability. Researcher led interviews will focus on the participants perceptions of the activities and decision making of exercise selection by selecting components that they are confident to perform which is a key element to creating a practical and enjoyable exercise programme for the older population. This will co-create an intervention that is accessible, acceptable, and appropriate for older adults. The study will establish the physical impact and practicalities of a novel elastic band resistance exercise intervention in older adults by performing force plate posturography and researcher led interviews that will focus on the participants perceptions of the activities and intensity levels to co-create an intervention that is accessible, acceptable, and appropriate for older adults.
Obesity is a global health problem. It changes the measurement of the human body and makes a big change to move the body. The increased weight and mass change the way the limbs and whole body generate and react to force Excess fat also interferes with joint-muscle interactions that are important for functional capacity and postural balance The tendency to increase the thickness of the abdomen contributes to anterior movement of the COM of the body. The purpose of the study is to investigate the biomechanical effect of weight on foot stability in children.

One of major challenges in orthodontics is to inhibit relapse and ensure stability of treatment outcomes. Retention is the phase of orthodontic treatment that attempts to keep teeth in the corrected position after correction with orthodontic braces. Without retention there is a tendency for the teeth to return to their initial position (1). Retention is usually necessary to overcome the elastic recoil of the periodontal supporting fibers and to allow remodeling of the alveolar bone. The bonded orthodontic lingual retainer constructed from composite and orthodontic wires provides an esthetic and efficient system for maintained retention and has been shown to be an effective means of retaining aligned anterior teeth in the post treatment position in the long term. This has been in popular use as a method of retention since the late 1970s (2). The traditional retainers, which are still in use, are multi-strand stainless steel retainers such as Penta-one® 0.0215 (Masel Orthodontics, Carlsbad, CA, USA). The main problem with multistrand stainless steel retainers is their high rate of failure. Clinical studies indicate that 5% to 37% of mandibular retainers fail during retention in some form, either bond failure or wire breakage (3-5). Reliance Orthodontic Products, Inc. (Itasca, IL, USA) recently introduced a bonded retainer system (Ortho-Flextech™ chain). This retainer's bonding is claimed to be quick and easy by reducing chairside time and eliminating laboratory costs (6). One other recently introduced retainer is Memotain™ (CA-Digital in Mettmann, Germany). Memotain is a CAD/CAM fabricated lingual retainer made of 0.014 X 0.014-inch rectangular nickel-titanium. The wire is highly flexible and custom cut to precisely adapt to the patient's lingual tooth anatomy. According to manufacturer, Memotain offers numerous perceived advantages to traditional multistranded lingual wires, including no need for wire measuring or bending, individually optimized placement, greater accuracy of fit, tighter interproximal adaptation, less tongue irritation, better durability, and resistance to microbial colonization (6). However, randomized clinical trials are necessary to determine whether these advantages are substantiated with scientific data. A recent review by the Cochrane group concluded that to date there is insufficient evidence to single out any particular retention strategy as the preferred method: it was recommended that future studies should include true randomization, reporting of dropouts, adequate sample size calculation, and a minimum follow-up period of 3 months (8). Thus, the aims of this multicenter, randomised controlled trial are: - To compare and evaluate the effectiveness and failure rate of Penta-one multistrand, Ortho-Flextech and Memotain retainers with each other - To compare the possible complications between the three retainers over time - To establish the cost-effectiveness of the three retainers - To evaluate the effectiveness of sandblasting in the retention of the wires
Introduction. The most popular injuries in volleyball are the ones who occur in knee joints, due the jumps and landings that happen through the game. For this reason there is a high index of loss of stability because of the dynamic valgus during the landing, a loss of balance and a decrease of power during the jumps. Objective. Evaluate the effectiveness of neuromuscular training in combination with strengthening of CORE in the improvement of knee joint stability, balance and power in vertical jump in volleyball players from 18 to 25 years old. Study design. Randomized, multicenter, single-blind clinical study with follow-up period. Methods. The study will be realized with an initial sample of 30 players, which in a random way, will be divided into two groups: experimental and control. It will be realized an initial evaluation where sociodemographic, anthropometric and clinical measures will be taken, and the study variables: knee joint stability (single leg squat test), balance (star excursion balance test) and vertical jump (sargent jump test). The intervention will last six weeks, with two sessions per week of approximately twenty minutes each. Expected results. The investigators expected to observe improvement in the stability in the knee joint, balance and power in the vertical jump in 18-25 years volleyball players that have received a neuromuscular training with strengthening of CORE.
A retrospective one-time evaluation of total knee patients one year or more postoperative, to compare antero-posterior (AP) stability with the TELOS Stress device/stress x-rays and clinical outcomes. Multiple implant brand/models will be included in the study.

The proposed project is a Randomized Controlled study design. Seniors (age >65) willing to participate in the study will be shortly interviewed to assess eligibility according to the inclusion-exclusion criteria. The first 60 subjects who upon questioning were judged to meet the following inclusion criteria: 1. able to stand independently 90 seconds 2. able to walk 10 meters (with cane if necessary) 3. able to understand verbal instructions. The exclusion criteria will be: 1. Serious visual impairment 2. Inability to ambulate independently (cane acceptable, walker not). 3. Severely impaired cognitive status (score less then 24 in Mini Mental State Examination). 4. Persons with impaired communication capabilities. The whole project will be conducted over a period of 24 months. The proposed study is a randomized experimental intervention/ control group design. A total of 60 elderly volunteer subjects will be randomly assigned to two groups, exercise group (30) and control group (30). Twelve training periods will be performed with 8 subjects participating in training during each period (4 exercise groups). The exercise group will meet on 24 occasions over a period of 12 weeks (2 times/week). Gait and balance function will be tested in both groups with well established measuring techniques before and after the training period. The measuring techniques 1. Medical background variables. 2. Berg Balance Scale. 3. Late life Function and Disability Instrument. 4. Get up and go test - stand up and walk 3 meters turn around and walk back to the chair. 5. Fall Efficacy Scale 6. Fall incidence and fall severity. 7. 6-minute walk test. The control group will not perform any specific balance training during the 12 week period. These individuals from control will participate in a separate exercise program after the training period. The water training intervention is performed on different levels where each level reflects different increasing demands on the postural control system. The water exercises also include perturbation exercises that trigger specific reflex-like balance responses. On each level the instructor can instantly modify an exercise to be more or less challenging for each participant.
