Use Cases:

Eligibility concerns A school-based OT receives a consult 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 supports 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 automoticity- the degree to which writing is automatic, requiring minimal to no concious thought going to letter formation. When automoticity 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 a interdiciplinary consult is competed 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 is 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 clinicians need quantified data to track progress and justify continued therapy.

What KHA Provides: Precise measurement of motor control that detects subtle deficits and documents recovery trajectory. Pressure regulation, movement smoothness, speed, spatial organization, and automoticity are all quantified and tracked over time.

Cognitive Decline, Movement Disorders, and Aging

The Challenge: An 49-year-old has noticed her handwriting has changed- smaller, shakier, slower. She states it requires far more effort to concentrate on forming the letters. Is this normal aging? A medication side effect? A sign of some neurological changes warranting a full evaluation by a neurologist? The handwriting change is visible, but the underlying cause isn't- and early identification of the cause is important to understanding changes in function.

What KHA Provides: Detection of subtle motor changes that may precede clinical diagnosis. Research shows handwriting kinematics change years before progressive degenerative neurological conditions are formally diagnosed. KHA captures the metrics that matter according to research: micrographia patterns, tremor signatures, speed degradation, and pressure dysregulation.

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, clinicians have documentation to support services. 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 reaquisition.

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 holistic documentation of progress and support continued insurance authorization.

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: An individual with essential tremor begins new medication. KHA assessments before and after medication change provide objective data on pharmacological affects on fine motor control.

Use Cases:

Screening in primary care: A geriatrician incorporates KHA into annual wellness visits for patients over 65. Subtle changes in motor patterns over successive years trigger referral to neurology to take a closer look before any additional symptoms may become clinically obvious.

Differential assessment: A 68-year-old presents with memory complaints. Neuropsychological testing is inconclusive. KHA assessment shows intact motor patterns, suggesting cognitive rather than motor etiology or reveals subtle motor patterns that warrant a referral to a different specialist.

Progression monitoring: A patient with early Parkinson's is monitored incrementally. KHA documents motor changes over time, providing objective data for medication adjustments, treatments, and functional planning.

Research participation: A memory clinic uses KHA to screen participants for longitudinal studies. Consistent, objective motor measurement at each visit supports research on early biomarkers.

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 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 seemless scoring and compilation of results across cites and 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.
