How this affects your claim in practice
In an overuse injury claim, the diagnosis is only the starting point. The records should connect nerve conduction study, ultrasound or specialist report where relevant and task frequency and force description with the worker's practical limits, including grip strength, keyboarding, tool use, overhead work and lifting tolerance and dominant-hand limits and two-handed tasks. If the insurer disputes whether repetitive work materially contributed, the response should address that reason directly.
Assessment source
- NSW Guidelines for the Evaluation of Permanent Impairment, paras 1.8-1.12: NSW Guidelines control the assessment method and AMA5 is used only where adopted and not modified.
- NSW Guidelines para 1.12: AMA5 Chapter 18 pain is excluded; chronic pain is assessed through the underlying diagnosed condition, while CRPS is assessed under the relevant NSW method.
- NSW Guidelines para 1.15: assessment should usually wait until maximum medical improvement, meaning the condition is stable and unlikely to change substantially in the next year.
- NSW Guidelines para 1.24: the effect on activities of daily living must not be used to increase or reduce an upper-extremity impairment calculated under the applicable upper-limb method.
- NSW Guidelines paras 1.26 and 2.8: values are rounded at each conversion stage; digit impairment converts to hand impairment, hand and other regional values convert to upper-extremity impairment, and AMA5 Table 16-3 converts upper-extremity impairment to WPI.
- NSW Guidelines paras 2.5 and 2.20: active movement is measured with a goniometer or inclinometer, passive movement is recorded for clinical comparison only, unreliable readings should be repeated, and the uninjured opposite limb may provide the worker's normal baseline.
- NSW Guidelines paras 2.8-2.13: values within one joint are added, same-limb regional values must be expressed in a common unit before combination, a deficit caused solely by a peripheral nerve lesion is not also rated as abnormal movement, and strength is used only in rare permitted cases.
- NSW Guidelines paras 2.14-2.20 modify the shoulder, biceps, impingement, joint-surface fracture and epicondylitis methods in AMA5 Chapter 16; para 2.21 directs upper-limb CRPS to the NSW Chapter 17 method rather than an AMA5 Chapter 16 or Chapter 18 pain rating.
- NSW Guidelines para 2.4: maximum upper extremity impairment is 60% WPI, equivalent to amputation through the shoulder.
What injuries or conditions may be assessed?
An overuse injury may be diagnosed as tendinopathy, tenosynovitis, bursitis, epicondylitis, nerve compression or another structure-specific upper-limb disorder.
- A general overuse label should be replaced by the accepted anatomical diagnosis before a permanent impairment method is selected.
Symptoms and findings that matter
Condition-specific findings may include local tendon provocation, repeatable active joint restriction, sensory loss in a named nerve distribution or measurable motor weakness.
Task frequency and force help explain causation and duties, but they do not become part of the WPI arithmetic.
What investigations are usually relevant
Investigations for overuse injury may include contemporaneous GP, specialist, physiotherapy or hand-therapy records identifying the exact diagnosis and progression to maximum medical improvement and ultrasound, MRI, X-ray, CT, operation reports or arthroplasty records where they explain tendon, labral, joint, fracture or surgical findings. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- Nerve conduction studies or EMG where clinically relevant, interpreted with the sensory and motor examination rather than used alone.
- Repeat active movement measurements and a clear note of whether pain, guarding or inconsistency affected the examination.
- Duties evidence describing overhead reaching, lifting, pushing, pulling, gripping, keyboard work, tool use and forearm rotation where relevant.
How WPI is assessed for this body part
Overuse WPI follows the method for the diagnosed tendon, joint or nerve. A conditional diagnosis-based value is used only when every NSW criterion is met.
Where movement and diagnosis-based methods both validly describe the same condition, the applicable NSW selection and non-combination rules prevent duplicate rating.

Worked assessment illustrations
These examples paraphrase the assessment reasoning in the source material. They explain method only and are not predicted outcomes.
Illustration 1
Overuse condition without measurable permanent loss
Assumed facts: Assume an accepted tendinopathy remains intermittently painful after treatment but active movement is full and repeatable and no special diagnosis-based NSW criteria are satisfied.
Method: The assessor cannot invent an overuse percentage. The recognised structure-specific method must produce an assessable result.
Illustrative outcome: On those assumed facts, symptoms and exposure do not by themselves establish WPI. This does not determine any individual assessment.
Source: NSW Guidelines paras 1.12, 2.5-2.13 and applicable diagnosis-specific provisions
What usually does not increase WPI
Pain, tenderness, weakness complaints or an imaging label without a stable measurable impairment.
Passive movement loss used as though it were active movement impairment.
Grip or other strength loss used to duplicate pain, restricted movement, deformity or nerve loss.
An activities-of-daily-living adjustment added to or subtracted from the calculated upper-extremity value.
The same functional loss counted once under a nerve method and again as restricted movement.
Evidence checklist
The records for overuse injury should include the accepted injury description and any dispute notice identifying the body part and diagnosis and repeat active range-of-motion measurements and opposite-side comparison where appropriate. They are most useful when the diagnosis, examination and practical restrictions are consistent.
- Imaging, operative reports and treatment records for the actual tendon, joint, fracture or arthroplasty condition.
- Sensory mapping, motor testing, static two-point discrimination or electrodiagnostic evidence where a nerve lesion is alleged.
- Work-duties and therapy records explaining the practical movement or nerve function affected.
How this injury commonly happens at work
Work-related overuse injury can arise through high-repetition tool, keyboard, scanning or gripping work and sustained wrist or elbow posture. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related overuse injury can arise through forceful hand use and vibration exposure. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For overuse injury, an insurer may dispute whether repetitive work materially contributed and whether symptoms are unrelated or constitutional. The written decision should be answered with evidence directed to those reasons.
Further disputes about overuse injury may concern whether modified duties truly reduce repetition and force. The decision notice should identify which issue is relied on and the evidence said to support it.
Treatment and surgery issues
Depending on the diagnosis and treating opinion, management of overuse injury may involve splints, hand therapy, injections, decompression or tendon release where supported. The request should explain the expected functional benefit and its connection to the accepted injury.
Weekly payments and work capacity
Capacity evidence for overuse injury should address grip strength, keyboarding, tool use, overhead work and lifting tolerance and dominant-hand limits and two-handed tasks. Proposed duties must be sustainable for the proposed hours, not merely possible once.
For overuse injury, capacity evidence should address safe duties that avoid repetition or forceful use and weekly payments where partial capacity is disputed. The question is whether those activities can be performed safely, reliably and for the proposed hours—not whether a task can be attempted once.
How NSW Work Injury Claim can help
For overuse injury, a claim review can help to separate diagnosis, work exposure and capacity evidence and test suitable duties against actual hand, wrist, elbow or shoulder demands. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
For overuse injury, a claim review can help to review treatment denial reasons and IME assumptions and plan WPI or dispute steps where appropriate. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
Common questions about overuse injury claims
How can work cause or aggravate overuse injury?
For overuse injury, the relevant work history may include high-repetition tool, keyboard, scanning or gripping work, sustained wrist or elbow posture, and forceful hand use. A claim still depends on the actual chronology and medical evidence. The records should identify what changed, when symptoms began or worsened, and how the diagnosed condition affects the worker's duties.
How is WPI assessed for overuse injury?
For overuse injury, overuse WPI follows the method for the diagnosed tendon, joint or nerve. A conditional diagnosis-based value is used only when every NSW criterion is met. Condition-specific findings may include local tendon provocation, repeatable active joint restriction, sensory loss in a named nerve distribution or measurable motor weakness. The assessor must apply the NSW Guidelines to the accepted, stable condition; the diagnosis or an operation does not by itself determine a percentage.
Which records are most useful for an overuse injury assessment?
An overuse injury assessment commonly needs the accepted injury description and any dispute notice identifying the body part and diagnosis, repeat active range-of-motion measurements and opposite-side comparison where appropriate, imaging, operative reports and treatment records for the actual tendon, joint, fracture or arthroplasty condition, and sensory mapping, motor testing, static two-point discrimination or electrodiagnostic evidence where a nerve lesion is alleged. Those records are most useful when they describe the same diagnosis, examination findings, treatment history and practical work restrictions.
What does an insurer commonly dispute about overuse injury?
For overuse injury, common issues include whether repetitive work materially contributed, whether symptoms are unrelated or constitutional, and whether modified duties truly reduce repetition and force. The response should address the insurer's stated reason with the relevant chronology, clinical findings, investigations and duties evidence rather than relying on the diagnosis alone.
How can overuse injury affect weekly payments and suitable duties?
Capacity evidence for overuse injury may need to address grip strength, keyboarding, tool use, overhead work and lifting tolerance, dominant-hand limits and two-handed tasks, and safe duties that avoid repetition or forceful use. A certificate should describe what the worker can do safely and sustainably. Proposed duties should then be checked against those restrictions and the real demands of the job.
What does not establish WPI for overuse injury by itself?
For overuse injury, pain, tenderness, weakness complaints or an imaging label without a stable measurable impairment. WPI depends on the accepted injury, objective findings and the method required by the NSW Guidelines after the condition has stabilised.
