Impacts Post Concussion with Dual-Task Gait Balance Control
Impacts post concussion with dual-task balance control Free Phone Consultation As the recognition of concussions in adolescent populations continues to grow, there is still no universally agreed-upon regulation for returning to activity post-injury. While traditional protocols rely heavily on symptom checklists and basic cognitive assessments, recent clinical research shows that hidden deficits—specifically in dual-task gait and balance control—often persist long after an athlete feels “ready” to return to play. It has been hypothesized that gait stability during dual-task walking may be particularly sensitive to long-term disruptions after a concussion. Understanding how brain injury impacts movement during these complex tasks is crucial for preventing premature return-to-activity and reducing the risk of secondary injuries. What Is Dual-Task Gait Testing? Dual-task gait testing evaluates a patient’s ability to walk (a motor task) while simultaneously completing a cognitive task, such as counting backward, answering questions, or processing visual cues. Walking normally requires dynamic coordination between the vestibular system, vision, and executive brain function. When healthy, your brain handles walking and cognitive processing seamlessly. However, following a mild traumatic brain injury (mTBI), the brain’s processing capacity is compromised. When forced to multitask, gait mechanics often deteriorate. What the Research Says About Post-Concussion Balance Control A key clinical study examining adolescent recovery looked at a cohort of adolescents who returned to activity within two months of their injury. The participants’ cognition, symptom severity, and balance control during single-task and dual-task walking were observed before and after returning to pre-injury activities. Key Findings From the Study: Persistent Balance Deficits: Even after reporting normal symptom scores and returning to pre-injury activities, participants demonstrated increased medial/lateral (side-to-side) center of mass displacement. Elevated Gait Velocity Anomalies: Walking speed and stability fluctuated significantly under dual-task conditions compared to single-task walking. Premature Return Risk: Returning to high-demand sports or activities while these subtle balance impairments remain can increase the risk of secondary musculoskeletal injuries. Read the full study: Return to Activity after Concussion affects Dual-Task Gait Balance Control (PDF) Why Traditional Concussion Protocols Miss these Deficits Standard return-to-play guidelines traditionally rely on static balance testing (such as standing on one foot with eyes closed) and paper-and-pencil neurocognitive evaluations. While helpful, static tests do not replicate real-world athletic conditions. In sports, an athlete must run, change direction, process visual cues, anticipate contact, and execute tactical decisions simultaneously. Static balance tests miss the functional neurological strain caused by real-world movement. Incorporating dynamic, dual-task gait analysis bridges this gap, providing objective data on whether the brain is truly ready for sports-specific demands.

Exercise Prescription Patterns in Patients Treated with Vestibular Rehabilitation After Concussion
Exercise Prescription Patterns in Patients Treated with Vestibular Rehabilitation After Concussion Free Phone Consultation Dizziness and balance dysfunction are among the most persistent and debilitating symptoms following a mild traumatic brain injury (mTBI) or sports-related concussion. Clinical studies show that 23% to 81% of post-concussion patients report dizziness during the acute phase, and 16% to 18% continue to experience persistent dizziness three months after injury. While Vestibular Rehabilitation Therapy (VRT) is known to significantly reduce dizziness and improve postural control, understanding how expert clinicians sequence and progress exercise prescriptions provides valuable guidance for optimal recovery. A key retrospective study evaluated these exercise prescription patterns to reveal how physical therapists successfully treat vestibular deficits post-concussion. Study Overview & Patient Demographics The study analyzed a cohort of 104 post-concussion patients (mean age of 24) who received a customized vestibular rehabilitation home exercise program. Initiation of Therapy: Interventions began between 7 and 181 days post-concussion, with a median start time of 33 days. Frequency & Duration: Patients completed a range of 2 to 13 physical therapy visits (mean of 4 visits) with physical therapists who had at least 3 years of specialized experience in vestibular therapy. Exercise Customization: Standardized home exercise software (Visual Health Information, WA, USA) was adapted and progressed by treating therapists to match each patient’s functional deficits. The 5 Core Categories of Vestibular Rehabilitation Expert clinicians categorized prescribed exercises into five distinct domains based on patient needs: Eye-Head Coordination: Focuses on restoring gaze stability, vestibulo-ocular reflex (VOR) function, smooth pursuits, saccades, and convergence. Sitting Balance: Maintains upright trunk alignment and stability while seated, including weight-shifting tasks. Standing Static Balance: Challenges balance in stationary positions (e.g., single-leg stance, tandem positioning, or standing on foam pads). Standing Dynamic Balance: Involves weight transfer and balance movement while standing in place (e.g., marching, stepping side-to-side, or turning). Ambulation: Integrates dynamic balance with walking (e.g., forward/backward walking, gait with head turns, obstacle navigation, and running). Prevalence of Functional Impairments The study highlighted three primary areas where concussion patients experienced the most severe functional deficits: Eye-Head Coordination Impairments (95% of patients): Nearly all participants suffered from gaze instability or vestibulo-ocular reflex (VOR) disruption, causing severe symptom spikes during head or visual motion. Standing Static Balance Impairments (88% of patients): Most patients demonstrated postural instability even weeks after injury, increasing their fall risk and spatial disorientation. Ambulation Impairments (76% of patients): Dynamic walking deficits were widespread, resulting in slower gait speed, shortened stride length, and wider step width. Clinical Reasoning: Prioritizing Eye-Head Tracking First A critical finding of this research was the decision-making sequence used by specialized physical therapists. Therapists did not address ambulation impairments on the initial visit. Instead, initial care prioritized eye-head coordination and static balance. Addressing vestibulo-ocular dysfunction and gaze instability early in therapy reduces visual-motion sensitivity and stabilizes sensory input. Once eye-head coordination improves, patients can safely progress to dynamic walking, complex movement, and return-to-play protocols without overwhelming the nervous system. Overall, the study demonstrates that expert physical therapists prescribe exercise patterns post-concussion that closely parallel protocols used for unilateral vestibular hypofunction, underscoring the vital role of specialized vestibular care in concussion management.

Vestibular/Ocular Motor Screening in Assessing Concussions
Vestibular/Ocular Motor Screening in Assessing Concussions Free Phone Consultation Vestibular and oculomotor impairments are among the most frequent and persistent complications following a sports-related concussion or mild traumatic brain injury (mTBI). Up to 60% to 80% of concussed athletes experience visual symptoms or vestibular dysfunction, such as dizziness, double vision, nausea, or motion sensitivity. Traditional sideline assessment tools—such as cognitive testing (SAC/ImPACT®) or postural stability tests (BESS)—often miss isolated visual and vestibular deficits. The Vestibular/Ocular Motor Screening (VOMS) tool was developed specifically to fill this diagnostic gap by systematically evaluating symptom provocation during specific eye movements and head motion challenges. What Is the VOMS Assessment? The VOMS is a brief, objective clinical screening protocol designed for individuals aged 9 to 73. Prior to testing, patients rate their baseline symptoms across four domains: headache, dizziness, nausea, and fogginess on a 0 to 10 scale. Therapists then administer five specific subtests, recording changes in symptoms and measuring physical movement thresholds: Smooth Pursuits: Tests the ability to smoothly track a slow-moving target horizontally and vertically while keeping the head stationary. Saccades (Horizontal & Vertical): Evaluates rapid eye jumps between two fixed targets spaced 3 feet apart, tested both side-to-side and up-and-down. Near Point of Convergence (NPC): Measures the distance (in centimeters) at which double vision occurs as a target is brought slowly toward the bridge of the nose. Vestibulo-Ocular Reflex (VOR – Horizontal & Vertical): Assesses gaze stability by having the patient rotate their head side-to-side or up-and-down while maintaining focus on a fixed central target. Visual Motion Sensitivity (VMS): Evaluates visual-vestibular integration by having the patient rotate their head, eyes, and torso in unison while focusing on their thumb held at arm’s length. Key Diagnostic Findings & Metrics Landmark clinical studies demonstrate that the VOMS possesses high internal consistency and strong diagnostic sensitivity when screening for sports-related concussions: High Sensitivity for Concussion: Any single VOMS subtest that provocaes an increase in symptom scores (headache, dizziness, nausea, or fogginess) significantly increases the probability of a concussion diagnosis. Near Point of Convergence (NPC) Recession: An abnormal convergence distance of 5 centimeters or greater from the bridge of the nose serves as a primary marker for ocular motor convergence insufficiency post-injury. VOR & VMS Provocation: The VOR and Visual Motion Sensitivity subtests are particularly effective at differentiating concussed athletes from healthy controls, as visual-motion integration is highly vulnerable to head trauma. Clinical Impact on Targeted Concussion Rehabilitation Integrating VOMS into initial post-injury evaluations offers several clinical advantages: Phenotype Subtyping: Helps clinicians differentiate between vestibular-ocular concussions, cervical spine involvement, and anxiety-driven dizziness. Targeted Exercise Prescriptions: Pinpoints exact visual or vestibular deficits early, allowing physical therapists to prescribe immediate, customized gaze stabilization (VOR) and convergence therapy. Safer Return-to-Play Progression: Prevents premature clearance by ensuring an athlete’s visual tracking and motion sensitivity are fully restored alongside cognitive function. See full study.

Concussion Rehab Focusing on the Inner Ear and Cervical Spine
Concussion rehab focusing on the inner ear and cervical spine Free Phone Consultation Persistent dizziness, neck pain, and headaches are among the most common and challenging symptoms following a sports-related concussion or mild traumatic brain injury (mTBI). Because the mechanical forces involved in head trauma require as little as 4.5g to injure cervical spine tissues—far lower than the 70g–120g force typically needed to cause a concussion—brain injuries almost always co-occur with cervical spine strain. Disruptions to both the inner ear (vestibular system) and the cervical spine (neck) create overlapping symptoms, making targeted, dual-focus physical therapy critical for full recovery. The Overlap: Inner Ear vs. Cervical Spine Involvement Disentangling whether dizziness and balance issues stem from the inner ear, the neck, or both is essential for effective treatment planning: Vestibular System (Inner Ear): Responsible for sensing head position, linear motion, and rotational movement. Concussion-induced vestibular dysfunction often leads to room-spinning vertigo, gaze instability during head movements, motion sensitivity, and postural imbalance. Cervical Spine (Neck): High concentrations of proprioceptive nerve receptors in the upper cervical spine send continuous feedback to the brain regarding head-on-neck positioning. Mechanical strain to upper neck joints and muscles causes cervicogenic dizziness, stiffness, occipital headaches, and impaired spatial orientation. Sensory Mismatch: When the inner ear and cervical spine send conflicting signals to the brain, patients experience persistent disorientation, lightheadedness, and motion sickness. Key Research Findings on Combined Rehabilitation Landmark clinical trials evaluating post-concussion physical therapy demonstrate that treating either system in isolation is far less effective than addressing both simultaneously: Significantly Higher Clearance Rates: Patients with persistent post-concussion dizziness and neck pain who received combined cervicovestibular physical therapy were nearly 4 times more likely to be medically cleared for return-to-play within 8 weeks compared to those receiving standard rest and gradual exertion protocols alone. Accelerated Time to Recovery: Integrating cervical spine manual therapy with vestibular exercises dramatically shortened the duration of persistent symptoms. Reduced Post-Concussion Syndrome (PCS) Risk: Early intervention targeting upper neck joints and inner ear reflexes prevents chronic compensation patterns and reduces long-term disability. Essential Components of Cervicovestibular Therapy A targeted rehabilitation program focuses on restoring normal joint mechanics, visual tracking, and sensory integration: Cervical Spine Manual Therapy: Gentle joint mobilization, soft-tissue release, and deep cervical flexor retraining to reduce neck pain, restore range of motion, and alleviate cervicogenic headaches. Vestibulo-Ocular Reflex (VOR) Retraining: Gaze stabilization exercises that re-train the eyes to stay focused on a target while the head is in motion. Cervico-Ocular Reflex & Proprioceptive Exercises: Joint position error (JPE) testing and laser-guided target tracking to restore accurate head-on-neck spatial awareness. Habituation & Balance Training: Controlled exposure to symptom-provoking environments and dynamic standing balance tasks to reduce visual motion sensitivity. See full study.
