Effects of 4-week impairment-based rehabilitation on jump-landing biomechanics in chronic ankle instability patients.

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.

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.

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.

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 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).
