This book was released on 2012 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Lateral ankle sprains are the most common injury in sports, with an estimated 25,000 per day. Current research assesses postural control deficits following lateral ankle sprains; however most studies use static stances instead of dynamic stances. Most of the current research compares injured limb to non-injured limb, however bilateral impairments have been found to be present. Twenty Division I student athletes will be recruited to participate in this study, ten subjects will be NCAA Division I student athletes who have suffered a lateral ankle sprain. Control subjects will be healthy NCAA Division I student athletes, matched by height and gender with the injured subjects. Dynamic postural control will be evaluated by gait initiation, which will be assessed using the Vicon system and then compared to matched healthy control values. MANOVA revealed no significant difference in dynamic postural control following a lateral ankle sprain when compared to control group. Significant differences were found in range of motion assessment as well as perceived function assessment.

Available in PDF, EPUB and Kindle. Book excerpt: Context: Lateral ankle sprain is the most common lower extremity injury in sport. It is well documented that previous ankle sprains can predispose an individual to future injuries and is hypothesized that altered input from the damaged ligaments may inhibit motor neuron pool excitability and lead to diminished muscle activation and chronic weakness of surrounding muscles. This phenomenon, known as arthrogenic muscle inhibition (AMI), can be a limiting factor in rehabilitation and the pathways involved with these neuromuscular deficits are not completely understood. Objective: Determine the effect of acute LAS on reflex excitability of lower leg musculature over a 14 day period compared to healthy matched controls. Additionally, to determine the relationship between H-reflex and dynamic postural control, self-reported measures of function and pain in individuals with LAS within 36 hours of injury. Design: Case-Control. Setting: Clinical Laboratory. Participants: Eight patients with acute lateral ankle sprain (3 males, 5 females; age= 21±1.85 years, height=174.63±9.77 cm, mass=73.81±19.56 kg) and eight healthy participants (3 males, 5 females: age=20.38±1.60 years, height=173.99±9.21 cm, mass=73.98±17.87 kg) volunteered to participate in this study. All participants were individuals from the University community. Interventions: All participants reported for a total of 5 test sessions at 36 hours, 5, 7, 10, and 14 days following the initial ankle sprain; or from the day of enrollment as a healthy control. Spinal reflexive excitability of the lower leg musculature was assessed bilaterally in each participant as well as self-reported function and pain, and dynamic balance. Main Outcomes: For each lower leg muscle's spinal reflex excitability, a repeated measures 2x5 ANOVA was used to determine if differences existed between groups over time. Spearman's rho correlation coefficients were calculated in the injured group between measures of lower leg spinal reflex excitability and self-reported disability, pain, function, and dynamic stability, at 36 hours following the initial injury. Alpha levels were set a priori at P

Download or read book Long term Effects Following an Acute Lateral Ankle Sprain in a College aged Population written by Bethany A. Wisthoff and published by . This book was released on 2019 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ankle is the most common body part injured by an athletic population with ankle sprains consisting of 77% of all ankle injuries. Approximately 72% of patients following an ankle sprain have reported residual symptoms six to 18 months later. Of those that reported residual symptoms, 40% reported at least one moderate to severe symptom, which included: perceived ankle weakness, perceived ankle instability, pain, and swelling. Previous research has shown that approximately 30% of patients suffering an initial ankle sprain will develop chronic ankle instability. Chronic ankle instability (CAI) is defined by those that have suffered recurrent ankle sprains, may have prolonged symptoms, and may exhibit mechanical and/or functional instability. Functional deficits have been seen in those with CAI, specifically to postural control or dynamic balance. The overall purpose of the current study was to determine if differences existed in the severity of the ankle sprain, pain, and dorsiflexion range-of-motion (DFROM) and the long-term effects of talocrural joint laxity, ligament thickness, and dynamic balance measures after an acute ankle sprain (AAS) in a college-aged population. Secondarily, to determine if differences occur in these measures between AAS, CAI, and to those without a history of ankle sprains (CON). Those who experienced an AAS had increased inversion (INV) stress, INV talofibular interval (TI), and anterior drawer (AD) stress compared to CON and CAI. Anterior talofibular ligament (ATFL) thickness was greater in AAS than CON, and greater in CAI than CON. In DFROM, CAI had less ROM than CON. In the Y Balance Test (YBT), CAI had less relative reach distance in anterior (ANT), posteromedial (PM), and composite (COMP) compared to CON. AAS also had less COMP percentage than CAI and CON. As clinicians, we must be aware that those who sustain a lateral ankle sprain should be assessed in the areas mentioned (range-of-motion, ankle laxity, musculoskeletal ultrasound, dynamic balance) to determine if differences exist over time. This research shows that those that have sustained an AAS, regardless of whether or not they have sprained that ankle before, still show deficits in ankle laxity, ROM, and dynamic balance 6-months later; however, those with CAI continue demonstrating deficits over time.

Download or read book Ankle Function Alterations Following Acute Ankle Sprains Over a 14 Day Period written by Michael Sean Patrick Mayes and published by . This book was released on 2014 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The objective of this study was to determine the effects of an acute lateral ankle sprain on self-reported function, self-reported pain, self-reported global function, joint effusion, dorsiflexion range of motion, and dynamic stability over a 14 day period following injury compared to healthy matched controls. Design and Setting: A case-control design was conducted in a laboratory setting. Subjects: Twenty-nine participants with an acute lateral ankle sprain (LAS) were assigned to a LAS group (10 males, 19 females; 20.41 ± 2.18 years; 176.44 ± 11.00 cm; 74.22 ± 14.33 kg), and twenty-two healthy participants were assigned to a control group (11 males, 11 females; 20.95 ± 2.97 years; 178.61 ± 10.96 cm; 76.39 ± 13.81 kg). Procedure: Experimental measures All participants were asked to report for a total of five tests sessions done at 36 hours, 5, 7, 10, and 14 days following initial injury; or from the day of enrollment as a healthy control. Each testing session lasted approximately 1 hour, with self-reported function and self-reported pain was assessed using the FADI, FADI Sport and VAS. Dynamic balance was assessed using the SEBT anterior, posteromedial, and posterolateral reach directions. Ankle girth was measured using the figure-of-eight method. Dorsiflexion range of motion was assessed using a goniometer. Frequency of rehabilitative exercises athletic, athletic participation and use of therapeutic modalities was collected using a treatment questionnaire. Results: Significant differences were found fourteen days following injury in all self-reported outcomes in the LAS group compared to Healthy controls (P=0.05). Significant decreases DF were found up to seven days post injury (P=0.05). Significant dynamic stability deficits were seen up to fourteen days following injury in the anterior reach and posteromedial reach of the star excursion balance text (SEBT) (P=0.05). No significant findings were seen in the posterolateral reach direction of the SEBT (P=0.05) at any time point. No significant findings were seen in ankle girth (P=0.05) at any time point. Conclusion: Those who suffer from a LAS exhibit decreased self-reported function, decreased dynamic postural control, decreased DF range of motion, increased self-reported pain, and increased ankle girth. While studies investigating acute function alterations in ankle sprains for 14 days following injury are limited, these results should be taken into consideration when making rehabilitation and return-to-play decisions. Clinicians may need to consider the possibility that a LAS return-to-play protocol time frame should be increased further than two weeks post injury. Word Count: 396.

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 2018 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic ankle instability (CAI), a pathological condition characterized by repetitive bouts of the ankle giving way, commonly develops following a lateral ankle sprain injury. Individuals with CAI have been shown to exhibit deficits in postural control and alterations in movement dynamics, which have been suggested to be contributing factors to the recurrent injury paradigm. The purpose of this investigation was to conduct a comprehensive biomechanical analyses to examine the influence of CAI on postural control and movement dynamics during a single leg squat, side-cut task, and single leg landing on an inverted surface. Fifteen participants with CAI and fifteen participants without CAI completed the study following a between-subjects design, with limb serving as the repeated measure during the single leg squat. Each participant completed a single leg squat, side-cut task, and unexpected and expected single leg landings on a tilted surface. Results from the single leg squat and single leg landings on the tilted surface were analyzed using a 2 x 2 mixed-model ANOVA, while results from the side-cut task were analyzed using an independent samples t-test. Statistical significance was considered for all dependent variables when p

This book was released on 2014 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Context: Mechanical and neuromuscular deficiencies are commonly studied in participants with chronic ankle instability (CAI). Recent evidence suggests mechanical laxity alone may not characterize the condition of CAI. Alterations in the central nervous system (CNS) following ankle sprains are likely to characterize the condition of CAI, yet few studies have quantified CNS alterations directly in CAI populations. Ankle sprain copers are individuals that do not present with prolonged dysfunctions following an initial ankle sprain. There have been limited examination of CNS alterations in patients with ankle sprain history, and to our knowledge none that have attempted to comprehensively consider CNS and mechanical differences between CAI, ankle copers, and healthy control groups. Objective: Determine if differences exist in spinal reflex excitability and ankle laxity between ankle sprain copers, CAI patients, and healthy controls. To identify which variables best predict performance on the star excursion balance test (SEBT) for each group. Design: Case control study. Setting: Research laboratory. Patients or Other Participants: Thirty-five participants with CAI (17M, 18F; 21.97±3.55yrs; 169.26±8.35cm; 72.40±14.79kg), 26 participants categorized as ankle sprain copers (10M, 16F; 21.50±4.17yrs; 168.35±10.83cm; 73.22±19.84kg) and 22 healthy control participants (8M, 14F; 21.45±3.43yrs; 166.75±7.63cm; 67.07±13.50kg) volunteered. Interventions: Spinal reflex excitability was assessed using Hoffman reflex (H-reflex) testing. Participants' ankle laxity was measured with an ankle arthrometer. Corticomotor excitability was assessed using transcranial magnetic stimulation (TMS). Range of motion was assessed using the weight bearing lunge test (WBLT) and open kinetic chain dorsiflexion (OKCDF) was assessed using a bubble inclinometer. Dynamic postural control was assessed using the SEBT. Main Outcomes: Spinal reflex excitability was assessed for the maximal H-reflex and muscle-response, from which the H:M ratio was calculated. Ankle laxity was measured as the total displacement in the anterior-posterior directions (mm) and total motion in the eversion-inversion directions (degrees). Corticomotor excitability was analyzed using active motor threshold (AMT) and silent periods (SP). Dorsiflexion was measured as distance from the wall during the WBLT (cm) and as possible range of motion for OKCDF (deg). Normalized reach distances for the anterior, posterolateral, and posteromedial reach distances of the SEBT. One-way ANOVAs were used to make groups comparisons for each dependent variable. Significance was set a priori at P

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 Structural and Functional Adaptations of Ankle Stability Do Not Affect Symptomatic Response and Clinical Outcome written by Erik A. Wikstrom and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Lateral ankle sprains are the most common orthopedic injury in the United States. More than 70% of people who sprain their ankle will have a recurrent episode and about 50% will develop ankle instability. This disability decreases quality of life by limiting the activities that individuals can perform comfortably and with confidence. However, it is unclear why some people can inherently compensate or cope (copers) and others cannot (non-copers). This investigation explored structural and functional adaptations among copers and non-copers to determine how those adaptations might influence symptomatic response and performance based clinical tests. Specifically, we examined the structural (fibula position relative to the tibia and ligament stiffness) as well as functional adaptations (static and dynamic postural control) among the two patient populations and a control group. A total of 72 subjects were recruited (24 in each patient group and 24 healthy controls) and underwent a series of lateral radiographic (x-ray) images and a joint stiffness test of both the right and left ankle followed by a static and dynamic balance test. The results indicated that non-copers had significantly increased disability as shown by the FADI, FADI Sport, and SRQAF. Similarly, both copers and non-copers had increased joint stiffness when compared to healthy controls. In addition, differences in static and dynamic postural stability were revealed. However, the secondary variables examined in this investigation appear to have little influence on the primary outcome variables. However, none of the performance based clinical tests or secondary variables related to the inclusionary criteria or self-report symptoms of disability, which indicates the need to reexamine the variables that we have based our ankle instability research on.

This book was released on 2020-07-12 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Social Security Administration (SSA) administers two programs that provide disability benefits: the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. SSDI provides disability benefits to people (under the full retirement age) who are no longer able to work because of a disabling medical condition. SSI provides income assistance for disabled, blind, and aged people who have limited income and resources regardless of their prior participation in the labor force. Both programs share a common disability determination process administered by SSA and state agencies as well as a common definition of disability for adults: "the inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months." Disabled workers might receive either SSDI benefits or SSI payments, or both, depending on their recent work history and current income and assets. Disabled workers might also receive benefits from other public programs such as workers' compensation, which insures against work-related illness or injuries occurring on the job, but those other programs have their own definitions and eligibility criteria. Selected Health Conditions and Likelihood of Improvement with Treatment identifies and defines the professionally accepted, standard measurements of outcomes improvement for medical conditions. This report also identifies specific, long-lasting medical conditions for adults in the categories of mental health disorders, cancers, and musculoskeletal disorders. Specifically, these conditions are disabling for a length of time, but typically don't result in permanently disabling limitations; are responsive to treatment; and after a specific length of time of treatment, improve to the point at which the conditions are no longer disabling.
