This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Ankle bracing has not been studied for its effects of knee joint kinematics and kinetics in the adolescent female athlete. Hypothesis: A) A statistically significant mean increase of knee joint valgus and extensor moments and valgus angles would be found in the braced group during the drop vertical jump and the single log hop tests and B) A statistically significant mean decrease in knee joint varus and extensor moments and valgus angles will be found between pre- and post-test acclimation periods in the braced condition. Study Design: Randomized Controlled Trial. Methods: Fifteen adolescent female athletes performed Drop Vertical Jump (DVJ) and Single Leg Hop (SLH) tests without ankle bracing and with a lace-up style ankle brace. Subjects wore braces over a 1 week period and retested. Results: During the DVJ, bracing increased knee extensor moments during the first 50 ms of landing but had no affect on knee frontal plane moments. Bracing increased vertical ground reaction force (vGRF) within the first 50ms of landing, and peak vGRF with less time to achieve peak vGRF. During the SLH, bracing increased knee flexion at IC and decreased knee frontal plane displacement into valgus. Ankle bracing increased vGRF within the first 50ms of landing and decreased stance time. Conclusions: Ankle bracing increased vGRF and knee extensor moments during the first 50ms of landing. Clinical Relevance: The adolscent female athlete may be at risk for knee injury during the initial landing phse when wearing a lace-up style ankle brace.

Available in PDF, EPUB and Kindle. Book excerpt: The purposes of this study were to investigate the kinematics of two ankle brace testing protocols. They were drop landing on a slanted surface and the inversion drop test. Difference in kinematics and ground reaction forces of drop landing wearing an ankle brace on flat and lateral slant surfaces were also investigated. Eleven healthy subjects performed five trials in each of six dynamic movement conditions. They were an ankle inversion drop test on the inversion platform, drop landing from 0.45 m onto slant surface, and drop landing from 0.45 m onto flat surface with and without an ankle brace. A 7-camera motion analysis system was used to obtain the threedimensional kinematics. In addition, a force platform was used to measure the ground reaction forces (GRF) during drop landing. A 2 x 2 (brace x movement) repeated measures ANOVA was used to evaluate selected variables for inversion drop test and landing on slant surface (p

This book was released on 2008 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The purpose of this study was to compare a lace-up ankle brace with a no-brace condition on the ability to return an athlete with CAI to a stable state by measuring the TTS following a jump-landing task. Design: Repeated measures within-subject design. Setting: Athletic Training Research Laboratory. Patients or Participants: Ten subjects, five males and five females (18.5625±.814yr; 174.0963±7.191cm; 69.2937±8.277kg) that fit the criteria for chronic ankle instability participated in this study. Measurements: Subjects participated in two separate testing sessions during which a jump-landing task was performed with one of two conditions: lace-up ankle brace or no ankle brace. The brace condition was randomized. During each session, five trials of a jump-landing task were performed on each leg. The jump-landing task consisted of a single-leg landing from a double-leg jump height equivalent to 50% of the subject's maximum jump height. Subjects jumped off of both feet from a distance 70cm away from the center of the force plate, reached up and touched the indicated marker, and landed on the force plate on a single test limb. The landing leg was randomized. Ground reaction forces were used to calculate TTS in the medial/lateral (MLTTS) and anterior/posterior (APTTS) directions. The independent variables were Condition (brace, no brace) and Side (injured, non-injured). A separate two-within (Condition, Side) repeated measures ANOVA was performed for APTTS and MLTTS. Main Outcome Measure(s): APTTS and MLTTS. Results: For APTTS, the Side by Condition interaction was not statistically significant (F1,9 = .004; p=.952). For MLTTS, the Side by Condition interaction was not statistically significant (F1,9 = .023; p= .884). No measurements were found to be statistically significant in either direction. Conclusion: This study was designed to show if the use of an ankle brace, like the Swede-O Universal would assist those subjects with CAI in reducing the amount of time it takes for them to stabilize after a jump landing task. Although the results of this study do not support these conclusions with statistical significance, it may provide an important direction in examining the connection between TTS, ankle bracing, and those with CAI. There is a definite need for further testing on more subjects with CAI so we can make a better conclusion about the use of the Swede-O Universal and its ability to reduce time to stabilization after a jump-landing task.

Lawson and published by . This book was released on 2015 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined repeated bouts of fatigue and its influence on biomechanical variables of drop landings known as risk factors for ACL injury. A repeated measures ANOVA was performed on fatigued conditions and gender as the independent variables. The dependent variables studied included: max ground reaction force, time to peak ground reaction force, sagittal hip, knee, and ankle angles, frontal knee angles, and knee joint moments. A 20-sec wingate anaerobic test was used as the repeated fatigue protocol and 5-drop landings were recorded in each fatigue condition. Results indicated that no significant differences across fatigue groups for max vertical ground reaction force, time to peak ground reaction force, knee joint moments (sagittal, frontal, transverse planes), hip flexion, knee flexion, ankle flexion, and knee abduction angles. Gender was noted as a significant factor regardless of fatigue condition on max vertical ground reaction force, ankle and knee flexion, and knee abduction angles.

This book was released on 2023-11-23 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomechanical performance is a key to evaluating effectiveness in physical medicine and rehabilitation for neuromusculoskeletal disorders. Assessments can be applied to degenerative dysfunction (e.g., falls or knee osteoarthritis in older adults) and sports-related injuries (e.g., ankle sprain or anterior cruciate ligament injury). Patients' body movements and daily activity functions can be compared to the state of pre-injury condition or to the level of healthy individuals. Some cutting-edge studies have gone a step further and used biomechanical performance to develop physical medicine and rehabilitation approaches and explore the mechanisms behind their effectiveness. However, such studies are still relatively rare. This research topic is intended to encourage more relevant projects to be published. This research topic aims to encourage researchers to use biomechanical performance to design advanced physical medicine and rehabilitation approaches, evaluate the effectiveness of the rehabilitation approaches, and explore the mechanisms by which rehabilitation approaches work for neuromusculoskeletal disorders. Some studies have developed stretching approaches for the rehabilitation of knee osteoarthritis in older adults by measuring biomechanical performance during functional activities. Some studies indicated that the mechanism of physical activity to reduce falls in older adults lies in its effectiveness in increasing proprioceptive sensitivity, and further indicated that rehabilitation of proprioception may be a key to reducing falls in the fall-prone older adult population. Some other studies analyzed biomechanical performance in ankle ligament injuries to understand when, how, and why ligaments fail. As a result, this research topic will expand the application of biomechanical performance to better understand and treat neuromusculoskeletal disorders.
