Gait kinematics and kinetics in patients with chronic ankle instability and healthy controls: A statistical parametric mapping analysis.

Background: Chronic ankle instability (CAI) is associated with changes in gait biomechanics which may be related to chronic dysfunction. Traditional statistical models may be limited in their ability to assess the complex 3D movement of the lower extremity during gait. Multivariate analysis of the lower extremity kinematics may reveal unique biomechanical differences associated with CAI.

Ankle kinematics during a drop-vertical jump in patients with chronic ankle instability and healthy controls: A bivariate confidence interval comparison.

Background: Chronic ankle instability (CAI) has been associated with frontal and sagittal plane kinematic differences compared to patients with no history of ankle sprain during landing tasks. Single plane kinematics are often statistically compared to identify group differences, however, the complex, multi-planar motions of the ankle allow for unique kinematic adaptations at the joint and univariate waveform analysis may be limited in the assessment of joint motion. Bivariate confidence interval analysis allows for statistical comparisons to be made when considering the simultaneous frontal and sagittal plane kinematics of the ankle.

Objective: To determine effects of 4-weeks of impairment-based rehabilitation on lower extremity neuromechanics during jump-landing.

Design: Descriptive laboratory study.

Participants: Twenty-six CAI subjects (age = 21.

Effects of rehabilitation on joint-coupling in patients with chronic ankle instability.

Chronic ankle instability (CAI) is associated with kinematic changes in the lower extremity. Alterations in joint-coupling have been identified during gait in patients with CAI. Rehabilitation remains the gold-standard for clinical treatment of CAI but little is known on the effects of rehabilitation on joint-coupling variability.

Chronic ankle instability patients exhibit higher variability in lower extremity joint-coupling variability during drop vertical jumps.

Chronic ankle instability (CAI) has been associated with biomechanical alterations during landing tasks. While joint coupling differences have been reported during gait in patients with CAI, there is no known research assessing joint coupling during a drop-vertical jumping (DVJ). Joint coupling variability measure may provide information on the sensorimotor health of these patients.

Lower Extremity Biomechanics During a Drop-Vertical Jump in Participants With or Without Chronic Ankle Instability.

Context:   Chronic ankle instability (CAI) is a condition characterized by range-of-motion, neuromuscular, and postural-control deficits and subjective disability, reinjury, and posttraumatic osteoarthritis. Differences have been reported in kinematics, kinetics, surface electromyography (EMG), and ground reaction forces during functional tasks performed by those with CAI. These measures are often collected independently, and the research on collecting measures simultaneously during a movement task is limited.

Comparison of Muscle Temperature Increases Produced by Moist Hot Pack and ThermoStim Probe.

ThermoStim Probe (TSP) has recently joined the market as a superficial heating modality. Although there is limited research into the intramuscular heating capability of superficial heating modalities in general (moist hot pack [MHP], paraffin, warm whirlpool), no previous research has examined intramuscular heating capability of TSP. Evaluate rate and magnitude of intramuscular heating via TSP compared with hydrocollator MHP, and determine if TSP can increase tissue temperature 3°C-4°C (vigorous heating range).

Effect of Impairment-Based Rehabilitation on Lower Leg Muscle Volumes and Strength in Patients With Chronic Ankle Instability: A Preliminary Study.

Patients with chronic ankle instability (CAI) have demonstrated atrophy of foot and ankle musculature and deficits in ankle strength. The effect of rehabilitation on muscle morphology and ankle strength has not previously been investigated in patients with CAI. Our objective was to analyze the effect of impairment-based rehabilitation on intrinsic and extrinsic foot and ankle muscle volumes and strength in patients with CAI.

Lower extremity joint coupling variability during gait in young adults with and without chronic ankle instability.

Chronic ankle instability (CAI) is a condition resulting from a lateral ankle sprain. Shank-rearfoot joint-coupling variability differences have been found in CAI patients; however, joint-coupling variability (VCV) of the ankle and proximal joints has not been explored. Our purpose was to analyse VCV in adults with and without CAI during gait.

BeWell24: development and process evaluation of a smartphone "app" to improve sleep, sedentary, and active behaviors in US Veterans with increased metabolic risk.

Lifestyle behaviors across the 24-h spectrum (i.e., sleep, sedentary, and active behaviors) drive metabolic risk.

Effects of ankle destabilization devices and rehabilitation on gait biomechanics in chronic ankle instability patients: A randomized controlled trial.

Unlabelled: Patients with chronic ankle instability (CAI) have altered gait patterns, which are characterized by increased inversion positioning during gait. Ankle destabilization devices increase peroneus longus muscle activation during gait, which may increase eversion.

Objective: To determine whether incorporating destabilization devices into a 4-week impairment-based rehabilitation program has beneficial effects on gait biomechanics and surface electromyography (sEMG) compared to impairment-based rehabilitation without destabilization devices in CAI patients.

Rehabilitation for Chronic Ankle Instability With or Without Destabilization Devices: A Randomized Controlled Trial.

Context: Individuals with chronic ankle instability (CAI) have deficits in neuromuscular control and altered movement patterns. Ankle-destabilization devices have been shown to increase lower extremity muscle activity during functional tasks and may be useful tools for improving common deficits and self-reported function.

Objective: To determine whether a 4-week rehabilitation program that includes destabilization devices has greater effects on self-reported function, range of motion (ROM), strength, and balance than rehabilitation without devices in patients with CAI.

Differences in hip-knee joint coupling during gait after anterior cruciate ligament reconstruction.

Background: After anterior cruciate ligament injury, patients have increased risk for developing degenerative osteoarthritis, potentially due to the kinematic changes that persist after surgical reconstruction. Current research only describes single joint kinematic differences rather than the way in which two joints behave concurrently, termed joint coupling. The purpose of this study was to compare knee motion relative to hip motion in anterior cruciate ligament reconstructed and healthy limbs during walking and jogging.

Supervised rehabilitation versus home exercise in the treatment of acute ankle sprains: a systematic review.

In competitive sports medicine, supervised rehabilitation is the standard of care; in the general population, unsupervised home exercise is more common. We systematically reviewed randomized, controlled trials comparing outcomes for supervised rehabilitation versus home exercise programs. Supervised rehabilitation programs resulted in (1) less pain and subjective instability, (2) greater gains in ankle strength and joint position sense, and (3) inconclusive results regarding prevention of recurrent ankle sprains.

Altering Shank-Rear-Foot Joint Coupling During Gait With Ankle Taping in Patients With Chronic Ankle Instability and Healthy Controls.

Context: Lateral ankle sprain (LAS) is one of the most common injuries in active individuals. Chronic ankle instability (CAI) is a condition that commonly occurs after LAS and is associated with long-term disability and a high risk of multiple ankle sprains. Ankle taping is a commonly used intervention for the prevention of ankle sprains.

Shank-rearfoot joint coupling in young adults with chronic ankle instability: a cross-correlation analysis.

Aim: Chronic ankle instability (CAI) has been associated with changes in gait kinematics which may be associated with the continued instability in this population. Abnormalities in shank-rearfoot joint coupling during gait may be associated with CAI. Cross-correlation analysis provides an estimate of both synchronous and asynchronous coherency between shank and rearfoot motion during gait.

Shank-rearfoot joint coupling with chronic ankle instability.

Chronic ankle instability (CAI) results in longstanding symptoms and subjective feelings of "giving way" following initial ankle sprain. Our purpose was to identify differences in joint coupling and variability between shank internal/external rotation and rearfoot inversion/eversion throughout the gait cycle of CAI subjects and healthy controls. Twenty-eight young adults participated (CAI, n = 15, control, n = 13).

Insomnia treatment acceptability and preferences of male Iraq and Afghanistan combat veterans and their healthcare providers.

Sleep difficulty is a prevalent problem among returning Veterans. Although there is strong evidence for the efficacy and durability of cognitive-behavioral treatment for insomnia (CBT-I) in the general population, the interventions require motivation, attention, and adherence from patients to achieve successful outcomes. Given the unique characteristics of Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) Veterans who have experienced blast-related injuries and other trauma, CBT-I for these patients may require modification, including alternative delivery methods, to ensure effective implementation and positive outcomes.

Total synthesis of salicylihalamides A and B.

The paper illustrates two efficient routes to macrolactone 19 containing a 3-(para-methoxybenzyloxy)propyl side chain at C-15. The chiral center at C-15 was introduced by a Noyori reduction of keto ester 5. The intermediate common to both routes, aldehyde 8, was prepared from keto ester 5.

A formal total synthesis of the salicylihalamides.

The synthesis of the macrolactone 23 is described. The synthesis features a diastereoselective hydroboration of the chiral alkene 17 followed by a Suzuki cross-coupling reaction with the benzoate 5. The resulting seco acid 21 was converted to the macrolactone 23 by a Mitsunobu lactonization using immobilized triphenylphosphine.
