Independent occupational therapy expert witness opinion is provided with analysis directed to functional and vocational capacity across personal injury, insurance, and disability matters.
The focus is on how an individual performs within real-world demands - not simply whether tasks can be completed, but whether activity can be sustained, output maintained, and the cumulative requirements of daily life and employment met. Diagnosis alone does not determine capacity; the emphasis is on how impairment translates into observable limitation across performance, endurance, and reliability.
Central to this approach is the distinction between theoretical ability and capacity that is practically achievable and sustainable. Conclusions are grounded in whether function can be maintained over time within the expectations of real-world environments.
Functional and vocational capacity analysis addresses the key questions that arise across medicolegal contexts:
A structured analytical framework is applied to ensure conclusions are grounded in observable performance and consistent reasoning:
Capacity is assessed in relation to the demands of daily life and employment, rather than in isolation:
Functional and vocational capacity analysis underpins a wide range of medicolegal matters:

Functional capacity refers to the ability to perform tasks and activities within real-world environments, while vocational capacity relates to engagement in employment. In a medicolegal context, the analysis focuses on how these domains interact — whether functional ability can be translated into sustained, reliable work performance. Emphasis is placed on observable behaviour, endurance, and consistency rather than diagnosis alone. Conclusions are formed by determining whether capacity aligns with real-world expectations.
Distinction is made by examining whether activity can be performed consistently, repeatedly, and without deterioration over time. Capacity demonstrated in structured or controlled settings is considered in the context of whether it can be maintained within daily life or employment. Productivity, persistence, and tolerance for workload demands are key factors. Ability that cannot be sustained beyond short durations is not considered indicative of real-world capacity.
Sustainability is evaluated through endurance, fatigue, and the ability to maintain performance across consecutive tasks and days. This includes consideration of recovery between activities and the impact of cumulative workload. Patterns of performance are examined to determine whether capacity is stable or prone to decline. Function that leads to deterioration or reduced reliability is distinguished from capacity that can be maintained over time.
Consistency is assessed by comparing performance across tasks, environments, and timeframes. Observed function is examined alongside reported limitation to determine overall reliability. Variability is interpreted in context, including whether it aligns with the nature of impairment. Greater weight is given to repeated patterns of behaviour than to isolated observations when forming conclusions.
Analysis considers how different domains of function interact to influence overall performance. Physical tolerance, cognitive processing, and psychological factors such as stress response or behavioural patterns are evaluated together. The combined effect of these factors is examined in relation to real-world demands. This ensures conclusions reflect the complexity of functional capacity rather than isolated components.
Employability is determined by evaluating whether functional capacity aligns with the demands of available work, including productivity, reliability, and sustainability. This includes consideration of whether skills and experience can be applied within functional limits. Roles that cannot be performed consistently or within tolerance are excluded. Conclusions are based on compatibility with realistic employment expectations
Occupational therapy medicolegal opinion is limited to independent assessment of functional and vocational capacity. It does not extend to costings, care needs assessments, treatment recommendations, or rehabilitation planning. This ensures conclusions remain objective and focused on functional issues relevant to legal and insurance determination. Maintaining this boundary supports independence and evidentiary integrity.
