NCT ID: NCT05608850 Recruiting - Posture Clinical Trials

Acute Responses of Postural Alignment, Kinematic Synergy, and Intermuscular Coherence to Postural Muscle Facilitation

Start date: October 25, 2022
Phase: N/A
Study type: Interventional

Clinicians frequently assess and intervene on postural alignment. However, research demonstrating the effects of exercise interventions in moving postural alignment toward an evidence-based standard is lacking. Part of the difficulty in establishing such evidence has been a lack of theory-motivated conceptions of what "good" posture is. In other words, the prevailing understanding of postural alignment is based on the negation of what has been observed to associate with bad outcomes. This study will build upon preliminary findings from our laboratory that define good postural alignment on theoretical grounds. The investigators will measure motion capture and muscle activation patterns during simple postural alignment tasks before and after 1) a corrective exercise intervention, or 2) a control intervention based designed to inhibit superficial muscle tension. The corrective exercise intervention is designed to counteract the natural patterns in which the human skeleton tends to collapse from a standing position under the influence of gravity. The control intervention consists of passive, partner-assisted stretching. Regardless of initial assignment, all participants will crossover (i.e. switch interventions) and repeat the study procedures after a 1-week washout period. Behavioral indicators of movement and nervous system coordination will be used to quantify alignment before and after exercise, as well as the consistency of those alignment patterns with theoretically-defined standards. The knowledge gained from this study will contribute to evidence-based definitions of healthy postural alignment and help identify effective interventions by which clinicians can promote good posture.

NCT ID: NCT05417399 Recruiting - Cerebral Palsy Clinical Trials

Influence of Hawthorne Effect and Dual-tasks on Gait in CP

Start date: September 1, 2022
Phase:
Study type: Observational

It is the clinical experience of the authors that some children with cerebral palsy who walk in crouch gait show sufficient knee extension during the clinical gait analysis, but walk in considerable knee flexion when they leave the gait laboratory. Possible differences between walking in a gait lab and walking in daily life may be caused by the effect of observational awareness in the lab (also known as the Hawthorne effect), and the lack of dual-tasks (DT) during the analysis (which are common during daily life walking). Since so far there is no technique to reliably measure gait kinematics in children with CP outside of the laboratory, the researchers aim to objectify the influence of both the Hawthorne effect and dual-tasks by introducing different conditions during a standard clinical 3D gait analysis.

NCT ID: NCT05114629 Completed - Electromyography Clinical Trials

Biomechanics of Adaptive Rowing in Active and Inactive Manual Wheelchair Users

Start date: September 14, 2021
Phase:
Study type: Observational

This research is being performed to characterize the rowing stroke in active and inactive individuals who use a manual wheelchair. The investigators will be looking at muscle activity of four shoulder muscles (upper trapezius, lower trapezius, serratus anterior, and posterior deltoid) and motion of the arms, shoulder blade, and trunk during rowing. This will be done for three rowing conditions (1: adapted rowing ergometer, 2: rowing ergometer from a chair, 3: standard seated row exercise using an elastic band [TheraBand]). The investigators are also looking at shoulder strength, range of motion, quality of life, and community participation.

NCT ID: NCT04221698 Completed - Kinematics Clinical Trials

Do Young Triathletes Have a Greater Predisposition to Suffer Running Injuries

Start date: October 1, 2018
Phase: N/A
Study type: Interventional

In running 70% of the lower limb, injuries are produced in the running segment. The vast majority of sports-related musculoskeletal injuries in young athletes are caused by overuse. Previous research has shown a clear association between running-related injuries and kinematic patterns, showing the existence of a causal relationship between biomechanical alterations and injures. According to the evidence, that real-time visual and auditory feedback based on gait retraining should be considered to treat injured runners or prevent injuries. However, no previous studies have been carried out on whether gait retraining decreases running-related injuries incidence in young triathletes. The investigators propose a study to determine the effect of gait retraining on the decrease in the number of running-related injuries and improve the running efficiency in young triathletes.

NCT ID: NCT04056078 Recruiting - Shoulder Pain Clinical Trials

Nordic Throwing Shoulder Project (NTS - Project)

Start date: February 24, 2020
Phase:
Study type: Observational

As a part of the Olympic program and with 150 countries in the international Handball Federation team handball has become a worldwide popular sport. Unfortunately, a large number of different types injuries have been reported among team handball players, and shoulder pain has some of the biggest incidence. In handball 44-75% of the athletes had a history of shoulder pain and a weekly prevalence of shoulder problems in 28% of the athletes. Shoulder pain has been reported to have an impact on the athletes' training activities, performance, and daily life. Several studies have established risk factors for shoulder injuries among overhead athletes, with a focus on the range of motion in glenohumeral joint (ROM), shoulder strength and scapula control. Injury occurrence results from a combination of possessing these different risk and the amount of throwing. Thereby training overhead sports must be considered a primary risk factor for shoulder injury. However, several studies have performed kinematics analysis of different throws techniques commonly used in team handball. But no studies havn't investigated kinematics and kinetics of different throwing techniques in relation to team handball players and the development of shoulder pain, and if a throwing technique or a wrong throwing technique stresses the shoulder joint more than other throwing techniques. In baseball it was found that youth pitchers throwing with a curveball was associated with a 52% increased risk of shoulder pain and the slider was associated with an 86% increased risk of elbow pain, and there was a significant association between number of throws and rate of shoulder pain. Two types of wind-ups are used in handball, and those different wind-ups also changed the throwing kinematics and throwing performance. Investigators found that the pelvis rotation was more important in the throw with the circular wind-up than in the whip-like wind up. In addition, the total throwing time was longer with the circular wind up. This could result in less stress and forces on the shoulder joint when compared with the whip like to reach the same performances. The questions arises whether the used throwing techniques of the handball players during training and matches are a risk factor for shoulder pain and if some throwing techniques cause bigger risk than other throwing techniques as the players could put more force on the shoulder and elbow joint.

NCT ID: NCT03439800 Recruiting - Rehabilitation Clinical Trials

Effects of Motor Imagery Training on Gait and Brain Activation Pattern of Individuals With Parkinson's Disease

Start date: February 15, 2018
Phase: N/A
Study type: Interventional

INTRODUCTION: Mental practice (MP) and action observation (AO) are characterized as cognitive strategies that contribute to motor planning and learning in diverse populations. Individuals with Parkinson's Disease (PD) are recent targets, since, with disease progression, they need external strategies to aid in motor organization. However, there is still no evidence of the efficacy of MP and AO in the gait of PD. OBJECTIVES: To compare the effects of physical practice preceded by MP and AO on gait performance in individuals with Idiopathic PD (IPD). METHODS: A controlled, randomized, single-blind clinical trial with 66 individuals with IPD, aged between 50 and 75 years, without cognitive deficit and in the moderate phase of the disease will be performed. For the inclusion and characterization of the sample, the following instruments / equipment will be used: (1) Identification form (sociodemographic, clinical and anthropometric aspects); (2) Mini Mental State Examination and Montreal Cognitive Assessment (cognitive level); (3) Hoehn and Yahr Scale (level of physical disability); (4) Revised Movement Imagery Questionnaire (sharpness of the mental image); (5) Qualisys Motion Capture Systems® (gait kinematics); (6) Emotiv Epoc + (electroencephalographic activity); (7) Unified Parkinson's Disease Rating Scale - UPDRS (motor function and activities of daily living); (8) Timed Up and Go Test - TUG Test (mobility); and (9) Parkinson's Disease Questionnaire - PDQ-39 (quality of life).Participants included will be randomly assigned to two groups: experimental (n = 33), who will participate in MP + AO and physical gait practice; and control group (n = 33), who will participate only in the physical practice of gait. Both groups will be submitted to 12 training sessions (3x / week, for 4 weeks) and will be reevaluated 10 minutes, 7 days and 30 days after the last training session with respect to items (4), (5), (6) and (8) of the evaluation. Primary outcomes will be velocity, stride length and range of motion of the hip and the secondary ones will be sharpness of the mental image, electroencephalographic activity and performance in the TUG Test. The normality in the data distribution will be verified through the Shapiro-Wilk test. The "t" test and the Mann-Whitney test will be used to verify the homogeneity of the groups in the baseline. A repeated measures ANOVA will verify the interaction between the groups at the moments observed.

NCT ID: NCT02716389 Completed - Reliability Clinical Trials

Cervical Kinematics' Reliability: Zero Positioning Using a 3-D-bulls Eye Spirit Level

Start date: March 2016
Phase: N/A
Study type: Interventional

The measurement of cervical spine range of motion (ROM) figures among the most common aspects of clinical diagnosis. Good reliability has been demonstrated for assessments using ultrasonic movement analysis systems, such as Zebris CMS 70 (Isny, Germany). However, in contrast to combined measurements of movement amplitudes (e.g., flexion plus extension in the sagittal plane), separating the respective components provides less reliable results. Current research suggest that this is due to the participants' determination of the zero position. This position is influenced by possible disposed treatments and, in particular, by the subject in case of subjective determination. The present study therefore aims to examine the test-retest reliability of separate ROM assessments using a bulls eye spirit meter. Twenty healthy participants will be included in the trial that adopts a two-armed randomized, crossover design. With a washout-period of one week in between, each subject participates in two sessions in a randomised order. In both sessions, cervical ROM (flexion/extension, rotation, lateral flexion) will be measured twice (with a five-minute wait period). In all measurements, the zero position will be determined by means of a bulls eye spirit level. The difference of the two sessions consists in the design of the waiting period. In one session, the subjects will keep the mask carrying the ultrasound markers on their head. In the other session, the mask will be removed during the break.
