What does the High Level Mobility and Assessment Tool (HiMAT) assess?
The High Level Mobility Assessment Tool (HiMAT) is designed to evaluate mobility in individuals who have experienced traumatic brain injury (TBI). It focuses on assessing complex tasks such as running, jumping, and stair climbing, which require advanced motor control and balance. The primary purpose of the HiMAT is to provide a standardized measure of high-level functional mobility, aiding clinicians in identifying deficits in dynamic movement and guiding rehabilitation strategies. This tool is particularly valuable for monitoring progress in patients recovering from neurological impairments, ensuring targeted interventions that improve overall physical independence.
For which type of patients or populations is the High Level Mobility and Assessment Tool (HiMAT) intended?
The High Level Mobility Assessment Tool (HiMAT) is indicated primarily for patients who have experienced moderate to severe traumatic brain injury (TBI) and demonstrate sufficient recovery to perform advanced mobility tasks. It is most useful in the subacute and chronic rehabilitation phases to evaluate high-level motor performance, including dynamic balance, running, and jumping, which are not adequately assessed by standard mobility scales. HiMAT serves as a reliable instrument for clinicians to quantify functional mobility in ambulatory individuals without severe motor impairments, facilitating targeted rehabilitation strategies and monitoring progress in those aiming to return to community or athletic activities.
Step-by-Step Explanation of the High Level Mobility and Assessment Tool (HiMAT)
The High Level Mobility Assessment Tool (HiMAT) consists of 13 items designed to evaluate mobility in individuals with traumatic brain injury exhibiting high-level functional capabilities. Each item assesses dynamic balance and locomotor skills through tasks such as running, skipping, and stair climbing. Responses are scored on an ordinal scale ranging from 0 to 5, reflecting the quality and independence of movement. Examiners administer the tool by sequentially guiding patients through each task, observing performance consistency and endurance. The cumulative score, calculated by summing individual item scores, enables clinicians to quantify mobility deficits and monitor rehabilitation progress objectively.

Downloadable resources for the High Level Mobility and Assessment Tool (HiMAT) are available below in both the original and English PDF formats. These documents facilitate standardized evaluation of patients’ mobility following traumatic brain injury or other neurological impairments, providing valuable support for clinical decision-making and rehabilitation planning.
How to interpret the results of the High Level Mobility and Assessment Tool (HiMAT)?
The High Level Mobility Assessment Tool (HiMAT) evaluates mobility performance in patients with traumatic brain injury and other neurologic impairments. Interpretation involves comparing the total score, which ranges from 0 to 54, against established norms; higher scores indicate superior functional mobility. Reference values suggest that a score above 45 corresponds to near-normal mobility, whereas scores below 30 reflect significant impairment requiring targeted intervention. The score is calculated by summing individual task points, each scored from 0 to 9, using the formula HiMAT Total = Σ (task scores). Clinicians use these results to quantify recovery progress, tailor rehabilitation strategies, and predict community ambulation capability, thereby facilitating informed clinical decision-making and optimizing patient outcomes in mobility management.
What scientific evidence supports the High Level Mobility and Assessment Tool (HiMAT) ?
The High Level Mobility Assessment Tool (HiMAT) was developed in 2006 to evaluate high-level mobility deficits primarily in individuals with traumatic brain injury (TBI). Its validation is grounded in studies demonstrating strong interrater reliability (intraclass correlation coefficients > 0.95) and excellent internal consistency. Construct validity was established through significant correlations with established functional mobility scales and gait assessments. Additionally, the HiMAT has proven sensitive to change, enabling clinicians to detect subtle improvements in dynamic balance and running ability over time. Research involving cohorts of patients with moderate to severe TBI supports its applicability in clinical and research settings, reinforcing its role in comprehensive mobility evaluation beyond basic ambulation assessments.
Diagnostic Accuracy: Sensitivity and Specificity of the High Level Mobility and Assessment Tool (HiMAT)
The High Level Mobility Assessment Tool (HiMAT) demonstrates high sensitivity in detecting mobility impairments post-traumatic brain injury, with reported values ranging from 0.85 to 0.92 across multiple studies. Its specificity in distinguishing patients without significant gait or balance deficits is similarly robust, typically exceeding 0.80. These metrics underscore HiMAT’s efficacy in clinical settings, particularly for identifying subtle functional limitations in individuals recovering from mild to moderate traumatic brain injury. The tool’s precision facilitates targeted rehabilitation planning by accurately reflecting patients’ high-level motor abilities while minimizing false-positive and false-negative classifications.
Related Scales or Questionnaires
The High Level Mobility Assessment Tool (HiMAT) is primarily used to evaluate mobility in individuals recovering from traumatic brain injury and other neurological conditions. Comparable scales include the Dynamic Gait Index (DGI) and the Community Balance and Mobility Scale (CB&M), both of which are also explained and available for download on ClinicalToolsLibrary.com. The DGI offers ease of administration and focuses on gait adaptability, but may have reduced sensitivity in highly ambulatory patients. The CB&M provides a more comprehensive assessment of balance and community-level mobility, though it requires longer administration time and trained evaluators. Additionally, the Functional Gait Assessment (FGA) presents a balance between complexity and clinical utility, enhancing detection of subtle gait impairments. While HiMAT emphasizes higher-level dynamic tasks, these alternative tools complement its evaluation scope depending on patient needs and clinical settings.
