Use Cases:

Eligibility concerns A school-based OT receives an evaluation request for a kindergartener with "poor fine motor skills." This classroom utilizes the KHA assessment paired with standardized reading scores. Assessment review, combined with clinical observation, shows motor metrics within normal limits but reveals the child had minimal exposure to handwriting instruction prior to the current year, and literacy growth and handwriting skills are growing together as expected. Data support Tier 1 support with the teacher and push-in whole-classroom support.

Progress monitoring: A first grader in the general education setting monitored quarterly in the general education setting. KHA tracks the metrics responsible for determining automaticity- the degree to which writing is automatic, requiring minimal to no conscious thought for letter formation. When automaticity is reached, the student is free to think about the content of their writing and what they want to convey- not the motor factors behind each letter. Velocity, pressure consistency, and legibility are monitored and considered over time- providing objective evidence of progress (or lack thereof) to guide appropriate intervention.

Differential screening: A third grader struggles with written output but reads at grade level; he receives additional services and support in other unrelated areas under an IEP. General education KHA data shows slow speed with high pause frequency during letter formation, suggesting motor automaticity issues rather than literacy delays. After data team meetings and an interdisciplinary consult is completed with parent or guardian permission, the stakeholders meet to discuss whether an OT evaluation is the best course of action.

IEP documentation: A parent has concerns about the need and level of services that are best for their child. KHA provides additional objective metrics, including percentile rankings against same-age peers, that highlight the amount of growth in response to instruction and, when needed, can provide baseline data for goal-writing.

ADULT REHABILITATION

Stroke, TBI, and Neurological event recovery

The Challenge: A 51-year-old individual recovering from a stroke wants to return to work as a financial advisor, but reports continued difficulty with writing tasks. How much function has been lost? What's the baseline for measuring recovery? Subjective observation recognizes some impairment, but professionals need quantified data to track progress with continued therapy.

What KHA Provides: Precise measurement of motor performance that quantifies subtle changes and documents recovery trajectory. Pressure regulation, smoothness of movement, speed, spatial organization, and automaticity are all measured and tracked over time.

Cognitive Decline, Movement Disorders, and Aging

The Challenge: A 49-year-old has noticed her handwriting has changed: smaller, less consistent, slower. She states it requires more effort to form letters. Her primary care team wants objective performance data to document the change quantitatively and track it over time.

What KHA Provides: Quantification of motor performance characteristics during structured handwriting tasks. Metrics include letter size variability, stroke velocity, pressure consistency, and movement variability. Performance is reported with normative percentile comparisons drawn from peer-reviewed reference data, supporting the licensed clinician's independent professional evaluation.

The Challenge: A second grader's written output is slow and difficult to read. Is it a motor problem? A literacy problem? Lack of instruction? Teachers and parents see the struggle but can't identify the source- and intervention depends entirely on the answer.

What KHA Provides: Objective data that distinguishes motor execution difficulties from cognitive/linguistic demands. When a child's writing speed or pressure patterns fall outside age-expected ranges, KHA provides documentation to support. When motor patterns are intact, the data points toward literacy-focused intervention instead. When literacy progress monitoring shows the student has the skills needed to express themselves in written form and the motor control to execute the task, KHA scores show the growth trajectories are proportionate and as expected.

Use Cases:

Baseline establishment: A young adult recovering from a TBI begins inpatient rehabilitation. Using KHA as part of the full assessment protocol provides objective metrics for fine motor domains, providing an additional documented starting point for measuring recovery and handwriting reacquisition.

Recovery tracking: A stroke survivor in occupational therapy is reassessed monthly. KHA shows progressive improvement in pressure consistency and velocity over 12 weeks: objective data to add to the holistic documentation of progress and support their continued improvement.

As part of a comprehensive return-to-work evaluation: A patient needs documentation of functional writing ability for vocational rehabilitation. KHA provides age-normed data showing where performance falls relative to same-age adults, supporting recommendations for accommodations or clearance.

Medication trial effects: Treatment response documentation: An individual receiving treatment that may affect fine motor control completes KHA assessments before and after treatment changes, providing objective performance documentation used to evaluate any changes that could be due to treatment response.

Use Cases:

Screening in primary care: Performance documentation in primary care: A geriatrician includes KHA performance measurements in annual wellness documentation for patients over 65, providing objective longitudinal motor performance data that the physician integrates with their broader clinical evaluation.

Differential assessment: Comprehensive evaluation support: A 68-year-old presents with memory complaints. Neuropsychological testing is inconclusive. KHA performance data shows motor metrics within normative reference ranges, providing objective measurement that the clinician integrates with the rest of the evaluation to inform their professional judgment.

Progression monitoring: Longitudinal motor performance tracking: A patient receiving treatment for a movement-related condition completes KHA assessments at regular intervals. KHA documents motor performance changes over time, providing objective data the clinician uses to inform treatment planning.

Research data collection: A memory clinic uses KHA to collect standardized motor performance measurements from participants in longitudinal studies. Consistent objective measurement at each visit supports research on motor performance characteristics over time.

UNIVERSITIES & RESEARCH

Academic Research and Normative Studies

The Challenge: Researchers studying handwriting, motor development, or neurological conditions need standardized measurement tools with millisecond precision. Existing methods are labor-intensive, subjective, or require expensive equipment that limits sample sizes.

What KHA Provides: Research-grade kinetic data collection on accessible hardware. Standardized protocols ensure reproducibility across sites. Minimal identifying data supports IRB-compliant research while maximizing scientific utility.

Use Cases:

Normative data collection: A university research team collects samples across age groups to establish updated developmental norms. KHA provides a consistent measurement methodology across all participants.

Intervention studies: Researchers comparing handwriting instruction methods use KHA pre- and post-intervention. Standardized metrics allow valid comparison across treatment groups.

Cross-site collaboration: Multiple institutions participate in a multi-site study on motor development. KHA ensures identical measurement protocols regardless of where data is collected, allowing seamless scoring and compilation of results across sites.

Longitudinal tracking: A research team follows a cohort of children from kindergarten through third grade. KHA provides consistent measurement at each time point, supporting analysis of developmental trajectories.
