Dual-task differences in individuals with chronic ankle instability: A systematic review with meta-analysis.

Background: Individuals with Chronic Ankle Instability (CAI) demonstrate altered gait mechanics, impaired proprioception, and decreased postural control. In addition, individuals with CAI have been found to have complex neurophysiological changes, including during dual-task perturbations. However, the results of studies on whether cognitive tasks affect postural control are inconclusive.

Participant-Level Analysis of the Effects of Interventions on Patient-Reported Outcomes in Patients With Chronic Ankle Instability.

Context: Intervention studies for chronic ankle instability (CAI) often focus on improving physical impairments of the ankle complex. However, using an impairments-focused approach may miss psychological factors that may mediate function and recovery. Patient-reported outcome (PRO) measures can be used to assess several dimensions of the health-related quality of life (HRQoL) and deliver enhanced patient-centered care.

Association of Ankle Sprain Frequency With Body Mass and Self-Reported Function: A Pooled Multisite Analysis.

Context: Ankle sprains result in pain and disability. While factors such as body mass and prior injury contribute to subsequent injury, the association of the number of ankle sprains on body anthropometrics and self-reported function are unclear in this population. Therefore, the purpose of this investigation was to assess differences in anthropometric measurements and self-reported function between the number of ankle sprains utilizing a large, pooled data set.

Platelet-Rich Plasma versus Corticosteroid Injection for the Treatment of Lateral Epicondylitis: A Systematic Review of Systematic Reviews.

Background: Lateral epicondylitis (LE) is one of the most commonly reported musculoskeletal disorders in the upper extremity. The mechanism of LE is repetitive motion that causes a strain of the extensor tendons. This consequently causes pain and tendinosis at the tendinous attachment site on the lateral epicondyle.

The effects of visual biofeedback and visual biofeedback scale size on single limb balance.

Background: Controlling postural sway relies on the assessment and integration of external sensory stimuli by the central nervous system. When there is a loss of one or more of the sensory stimuli, there is often a decrease in balance performance. Visual biofeedback (VBF) has become a popular method to improve balance because of the supplementation to natural visual information with visual cues of the center of pressure.

Does the Method of Administration Affect Reliability of the Foot and Ankle Ability Measure?

Background: Region-specific patient-reported outcomes (PROs) are commonly used in rehabilitation medicine. Digital versions of PROs may be implemented into electronic medical records and are also commonly used in research, but the validity of this method of administration (MOA) must be established.

Purpose: To determine the agreement between and compare the test-retest reliability of a paper version (FAAM-P) and digital version (FAAM-D) of the Foot and Ankle Ability Measure (FAAM).

The reliability and validity of a digital version of the Cumberland Ankle Instability Tool.

Purpose: The Cumberland Ankle Instability Tool is a common patient reported outcome used to assess those with Chronic Ankle Instability. However, paper versions of the Cumberland Ankle Instability Tool have only been assessed for reliability purposes. The purpose of this study was to assess the agreement and reliability of a digital version of the Cumberland Ankle Instability Tool-Digital.

Cortical Measures of Motor Planning and Balance Training in Patients With Chronic Ankle Instability.

Context: Motor planning, a prerequisite for goal-driven movement, is a complex process that occurs in the cortex. Evidence has suggested that motor planning is altered in patients with chronic ankle instability (CAI). We know balance training can improve balance, but we do not know if it also improves motor planning.

The Effects of Cognitive Loading on Motor Behavior in Injured Individuals: A Systematic Review.

Background: Research suggests that individuals with musculoskeletal injury may have difficulty negotiating physical tasks when they are combined with cognitive loads.

Objective: Our objective was to conduct a systematic review to understand the effects of increased cognitive demand on movement patterns among individuals with musculoskeletal injuries.

Methods: A comprehensive search of PubMed, MEDLINE, the Cumulative Index for Nursing and Allied Health Literature (CINAHL), and SPORTDiscus was conducted to find research reports that included a population that had previously experienced an ankle, knee, or low back injury, included an uninjured control group, and assessed a dual-task paradigm.

Predicting dynamic balance improvements following 4-weeks of balance training in chronic ankle instability patients.

Objectives: Balance training typically features as a central component of exercise-based rehabilitation programs for patients with lateral ankle sprain and chronic ankle instability (CAI). The purpose of this study was to conduct a responder/non-responder analysis using existing data to identify factors associated with improvements in dynamic balance performance in CAI patients.

Design: Secondary data analysis.

Increased Visual Use in Chronic Ankle Instability: A Meta-analysis.

Purpose: The underlying cause of balance impairments in chronic ankle instability (CAI) patients remains unknown, but an altered use of sensory information has been hypothesized as a potential cause. The purpose of this systematic review with meta-analysis was to determine whether CAI patients use somatosensory information to the same extent as uninjured controls during static single limb stance.

Methods: We searched PubMed, CINAHL, SPORTDiscus, and Scopus databases from origin to March 2016 using the combination of key words, including postural control, postural stability, single limb stance, single leg stance, single leg balance, single limb balance, and time to boundary (TTB).

Balance Training Versus Balance Training With STARS in Patients With Chronic Ankle Instability: A Randomized Controlled Trial.

Context: Both balance training and selected interventions meant to target sensory structures (STARS) have been shown to be effective at restoring deficits associated with chronic ankle instability (CAI). Clinicians often use multiple treatment modalities in patients with CAI. However, evidence for combined intervention effectiveness in CAI patients remains limited.

Effects of a stocking on plantar sensation in individuals with and without ankle instability.

Introduction: It is unknown whether footwear has a beneficial or deleterious effect on cutaneous sensitivity. We aimed to test a preliminary model of footwear and its effect on tactile perception among groups of controls, copers, and chronic ankle instability participants.

Methods: Light-touch thresholds were obtained for 45 participants (age: 20.

Cognitive loading-induced sway alterations are similar in those with chronic ankle instability and uninjured controls.

Performing a cognitive task while balancing can result in either increased or decreased sway depending on the nature of the cognitive task, and is commonly used in pathologic populations to evaluate postural performance. A total of 39 participants were recruited into two groups: uninjured controls (n=20, age: 21.9±2.

Plantar Cutaneous Sensitivity With and Without Cognitive Loading in People With Chronic Ankle Instability, Copers, and Uninjured Controls.

Study Design: Controlled laboratory study.

Background: Deficits in light touch have recently been identified on the plantar surface of the foot in those with chronic ankle instability (CAI) but not in uninjured controls. It is unknown whether copers display similar deficits.

The effect of instructions on postural-suprapostural interactions in three working memory tasks.

Examining postural control while simultaneously performing a cognitive, or suprapostural task, has shown a fairly consistent trend of improving postural control in young healthy adults and provides insight into postural control mechanisms used in everyday life. However, the role of attention driven by explicit verbal instructions while dual-tasking is less understood. Therefore, the purpose of this investigation is to determine the effects of explicit verbal instructions on the postural-suprapostural interactions among various domains of working memory.
