This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: It has been proposed that inadequate rest intervals may contribute to decreased performance of activities. However, previous research has not investigated the effect of rest interval on performance of the Star Excursion Balance Test (SEBT) in individuals with and without chronic ankle instability. Objective: To determine whether rest interval affects performance of the SEBT associated with chronic ankle instability (CAI) and whether neuromuscular function, postural control or biomechanics can be associated factors which may help discriminate between healthy individuals and those with CAI during the SEBT. Design: 2-group counterbalanced study. Participants: Participants included 24 individuals with a history of at least one ankle sprain in the past year and at least 2 episodes of giving way in the past 6 month prior to study enrollment, and 24 individuals with no history of ankle sprain or instability in their lifetime. Methods: Subjects completed 3 trials in each of the 3 reach directions (anteromedial, medial, posteromedial) in random order. A total of three visits were required in order to complete the 3 rest intervals (10, 20, 40 seconds). Normalized maximum reach distance, electromyographic (EMG) activation of tibialis anterior, peroneus longus, and medial gastrocnemius muscles, multiplanar motion of the lower extremity, coupling angles (CA) of lower extremity segments and maximum lateral center of pressure velocity were calculated and compared between groups in each direction for each rest interval. Results: Rest interval did not influence differences of reach distance, EMG ankle muscle activation, kinematics and center of pressure velocity between healthy individuals and those with CAI during the SEBT. However, the rest interval of 20 seconds demonstrated differences in CAs of tibial internal rotation/dorsiflexion (TIR/DF) and tibial internal rotation/eversion (TIR/EV) between healthy individuals and those with CAI during the SEBT. Overall, reach distance, mean amplitude of EMG ankle muscles, kinematics and joint CAs were different between healthy individuals and those with CAI during the SEBT regardless of rest interval. Discussion: Based on these results, differences exist in neuromuscular functions and biomechanics between healthy individuals and those with CAI when performing the SEBT. A rest interval time of 20 seconds between trials during the SEBT is an appropriate time to discriminate joint CAs of TIR/DF and TIR/EV between healthy individuals and those with CAI during the SEBT. These findings have implications for treatment and possible prevention of CAI.

This book was released on 2019-02-08 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: The control of balance by the central nervous system is crucial to maintain our posture and perform efficiently our daily motor tasks. This control requires the development of dynamical phenomena sub-served by highly-coordinated patterns of muscle activation/deactivation disseminated throughout the whole-body and called “postural adjustments”. Establishing the interaction between balance control, locomotion and cognition has important clinical implication, especially in term of falls prevention, and will improve our knowledge on the underlying neural correlates. This Research Topic provides an up-to-date picture of the relationship between postural adjustments, body balance and motor performance in healthy (young and older adults) and pathological participants. It includes 36 contributions (1 editorial, 28 original articles, 4 reviews and 3 methods articles) which are separated into four sections: 1. Postural maintenance and multisensory integration, 2. Anticipatory postural adjustments associated with voluntary movement, 3. Postural adjustments associated with predictable and unpredictable external perturbation, 4. Gait assessment and rehabilitation in aging. Beside their basic interest of unveiling the mechanisms behind motor control, results from the investigations of this topic are relevant to develop new methods or tools to improve postural stability and motor performance, with applications in the fields of neurodegenerative conditions, rehabilitation, ergonomics and sports sciences.

This book was released on 2009 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Chronic ankle instability (CAI) is associated with deficits in strength, balance, and static postural stability, however dynamic postural stability during transitional movements have received limited investigations. The purpose of this study was to assess dynamic postural stability in individuals with CAI during varying speeds of gait initiation (GI). There were twenty eight voluntary subjects, 14 (M8:F6) subjects with CAI and 14 (M8:F6) control subjects (healthy young athletes, HYA). CAI was assessed using the Foot and Ankle Ability Measure (FAAM) tool. Control subjects had no history of any LAS. Data was collected using two non-conducting forceplates and an electromagnetic tracking system. Subjects performed five trials of each task, first normal speed GI and then fast speed GI. There were no significant differences noted for both A/P and M/L movement and velocity of COP during S1. There were also no significant differences between groups for initial step length or initial step velocity. Lastly, there were no significant differences found between groups for COP-COM at the end of single support phase of gait. The results of this study suggest that GI may not be a challenging enough task to evoke deficits in postural control in individuals with CAI. The GI motor program likely remains unaffected by the development of CAI and these individuals are likely able to compensate for any functional deficits they may experience. Future research should investigate these motor programs using EMG data and also possibly secondary tasks that may challenge these individuals more.

This book was released on 2013 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The objective of this study was to determine the effectiveness of two intervention programs focusing on proximal alterations or distal alterations on improving dynamic postural control and self-reported disability in patients with chronic ankle instability (CAI). Design and Setting: A double blinded, randomized control trial was conducted in a laboratory setting. Subjects: Twelve patients with CAI were randomly assigned to an Ankle intervention group (4 males, 2 females; 21.5±2.81 years; 176.74±10.91 cm; 83.14±20.85 kg), or to an Ankle/Glut intervention group (2 males, 4 females; 19.5±1.52 years; 168.48±7.82 cm; 80.74±27.63 kg). Procedure: Experimental measures were measured pre- and post-intervention period. All participants filled out the Foot and Ankle Ability Measure (FAAM) and FAAM Sport during pre- and post-testing to test for improvement in self-reported function following the intervention. The Star Excursion Balance Test (SEBT) and Time to Stabilization (TTS) were tools used to assess dynamic postural control. Lastly, the participant's hip abduction strength (HABD) and external rotation strength (ER) were determined using a hand-held dynamometer. Hip ER was tested in a seated position, while HABD was tested in a sidelying position. Participants were randomly assigned to the Ankle or Ankle/Glut intervention group and took part in a four-week exercise program. The Ankle intervention group participated in traditional ankle rehabilitation of four directional therabands, wobbleboard, and single-leg balance exercises, whereas the Ankle/Glut intervention group took part in the same traditional ankle rehabilitation along with gluteal exercises of rotational lunges and rotational squats. Both groups met twice a week, for approximately 20 minute sessions, with the first exercise intervention occurring immediately following pre-testing of outcome measures and the day prior to post-testing after four-weeks. During the first week, the gluteal exercises were performed with no resistance. During the 2-4 weeks of the intervention, participants wore a weight vest to which 5% of body mass was added each week, resulting in resistances of 5%, 10%, and 15% of body mass during weeks 2, 3, and 4, respectively, of the intervention. Significance was detemined using dependent t-tests between pre and post values (p

Download or read book Handbook of Human Motion written by and published by Springer. This book was released on 2018-04-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Human Motion is a large cross-disciplinary reference work which covers the many interlinked facets of the science and technology of human motion and its measurement. Individual chapters cover fundamental principles and technological developments, the state-of-the-art and consider applications across four broad and interconnected fields; medicine, sport, forensics and animation. The huge strides in technological advancement made over the past century make it possible to measure motion with unprecedented precision, but also lead to new challenges. This work introduces the many different approaches and systems used in motion capture, including IR and ultrasound, mechanical systems and video, plus some emerging techniques. The large variety of techniques used for the study of motion science in medicine can make analysis a complicated process, but extremely effective for the treatment of the patient when well utilised. The handbook descri bes how motion capture techniques are applied in medicine, and shows how the resulting analysis can help in diagnosis and treatment. A closely related field, sports science involves a combination of in-depth medical knowledge and detailed understanding of performance and training techniques, and motion capture can play an extremely important role in linking these disciplines. The handbook considers which technologies are most appropriate in specific circumstances, how they are applied and how this can help prevent injury and improve sporting performance. The application of motion capture in forensic science and security is reviewed, with chapters dedicated to specific areas including employment law, injury analysis, criminal activity and motion/facial recognition. And in the final area of application, the book describes how novel motion capture techniques have been designed specifically to aid the creation of increasingly realistic animation within films and v ideo games, with Lord of the Rings and Avatar just two examples. Chapters will provide an overview of the bespoke motion capture techniques developed for animation, how these have influenced advances in film and game design, and the links to behavioural studies, both in humans and in robotics. Comprising a cross-referenced compendium of different techniques and applications across a broad field, the Handbook of Human Motion provides the reader with a detailed reference and simultaneously a source of inspiration for future work. The book will be of use to students, researchers, engineers and others working in any field relevant to human motion capture.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BACKGROUND: Ankle sprains are the most common injuries among physically active people, with 40-70% developing functional ankle instability (FAI), characterized by frequent episodes of "giving way" and sensations of joint instability. Kinesio Taping, ® an intervention that has recently gained popularity may help decrease postural control deficits related to FAI. This study examined the immediate and prolonged effects of Kinesio Taping® on postural control in subjects with FAI and investigated differences between healthy, coper, and unstable ankles as measured through single-limb balance on a forceplate. METHODS: Sixty physically active, college-aged participants (height: 172.5 ± 9.7 cm, mass: 74.2 ± 16.2 kg, age: 21.5 ± 2.6 years) were sorted into three separate groups: healthy control, copers, and FAI. Subjects were stratified using the Cumberland Ankle Instability Tool (CAIT) combined with their history of ankle injury. Dependent variables were time to boundary (TTB) measures and traditional center of pressure (COP) measures in both the mediolateral (frontal) and anteroposterior (sagittal) planes. Testing was performed at baseline, immediately after application of the tape, 24 hours post-tape application, and immediately after removal of the tape. RESULTS: Significant group main effects for COP standard deviation (F2,57 = 4.309, p = 0.018) and range (F2,57 = 4.918, p = 0.011) in the sagittal plane were noted. Significant condition main effects for TTB absolute minima (frontal plane, F 3,159 = 1.607, p = 0.015) and standard deviation (frontal, F3,138 = 5.710, p = 0.002 and sagittal plane, F3,141 = 0.889, p = 0.029) were also noted. Post hoc testing revealed decreased COP standard deviation and range for the ankle instability group compared to controls and significant improvements at 24 hours post-tape in all groups for TTB absolute minima (p = 0.025) and standard deviation (frontal plane, p = 0.002). CONCLUSIONS: Deficits in COP variables were seen in unstable ankles as compared to both healthy ankles and copers. Minor improvements in TTB measures after 24 hours of continuous wear of Kinesio® tape were observed in healthy, coper, and unstable ankles. Since between group differences were seen in COP measures, but improvements post-tape application were seen only in TTB variables, we can conclude that Kinesio® tape did not improve the specific postural control deficits experienced by unstable ankles. Therefore, while Kinesio® tape may provide a small benefit to postural control at the ankle, it does not appear to be effective at improving ankle instability deficits. Keywords: balance, time to boundary, center of pressure.
