The Hara Test is a multi-item assessment used in throwing athletes to screen shoulder, scapular and upper-limb kinetic chain findings that may relate to throwing symptoms. It should be treated as a structured clinical screen rather than a diagnostic test. Current overhead athlete literature supports assessing the whole kinetic chain, including the trunk, lower limb and scapular region, rather than focusing only on the shoulder joint.
A baseball pitcher reports shoulder discomfort during throwing, but isolated rotator cuff testing does not explain the full picture. Their symptoms may relate to scapular control, thoracic rotation, shoulder ROM, trunk timing, hip strength or fatigue.
The Hara Test provides a structured way to screen multiple shoulder and upper-limb kinetic chain findings in throwing athletes. It should not be described as diagnosing a specific injury. Its value is in identifying patterns that may need further testing or tracking.
Test name: Hara Test
Body region: Shoulder, scapula, upper limb and throwing kinetic chain
Purpose: Screen movement, posture, mobility and strength findings relevant to throwing shoulder symptoms
Positive finding: One or more abnormal or asymmetrical findings across the selected Hara Test items
Negative finding: No meaningful abnormal findings or side-to-side differences
Best used with: Shoulder ROM, scapular assessment, rotator cuff strength, thoracic mobility, hip/trunk assessment and throwing history
Key limitation: Current 2020+ diagnostic accuracy evidence for the exact Hara Test is limited
The Hara Test is a structured shoulder and upper-limb screen used in some throwing athlete settings. It is commonly described as including multiple items related to scapular position, shoulder mobility, strength and upper-limb kinetic chain function.
Because versions and item lists may vary, the exact items used should be recorded clearly.
The test is used to identify possible physical findings that may relate to throwing symptoms or performance limitations.
It may help guide follow-up testing for shoulder ROM, scapular control, rotator cuff strength, thoracic mobility, hip strength, trunk control and throwing workload.
The Hara Test assesses patterns across multiple shoulder and kinetic chain items. It does not diagnose a labral tear, rotator cuff tear, impingement syndrome or throwing injury.
Findings may reflect movement control, mobility, strength, asymmetry, fatigue or sport-specific adaptation.
This test may be useful for baseball pitchers, throwers, overhead athletes, racquet sport athletes and clients whose symptoms occur during repeated high-speed upper-limb actions.
Use when the client’s sport or task involves repeated throwing or overhead loading and you want a structured screen of relevant shoulder and kinetic chain findings.
Use caution with acute shoulder trauma, severe pain, recent surgery, high irritability, instability symptoms or any item that provokes symptoms beyond what is clinically useful.
Modify or defer individual items when needed.

Choose the Hara Test items to be used and record the version.
Most items are performed in standing, sitting or shoulder-specific positions depending on the item.
Observe shoulder, scapular, trunk and arm movement from the front, side and back as required.
Use manual contact only where needed for measurement or resistance testing.
Standardise the position for each item so side-to-side comparison is meaningful.
Assess the selected items, such as scapular position, shoulder ROM, strength, flexibility or movement control.
Ask the client to report pain, tightness, weakness, fatigue, throwing-related symptoms and whether symptoms are familiar.
A positive or abnormal finding is asymmetry, reduced control, pain, weakness, mobility restriction or item-specific abnormal result.
A negative finding is no meaningful asymmetry, pain or abnormal item response.
Stop any item if pain increases sharply, instability symptoms occur, compensation dominates or the client cannot perform it safely.
Do not combine all findings into a diagnosis. Record item-level results.
A positive Hara Test item may suggest a movement, mobility or strength finding that deserves further assessment. A cluster of findings may help guide training or return-to-throwing planning.
A negative Hara Test does not exclude throwing-related shoulder pathology. Throwing symptoms may still relate to workload, mechanics, fatigue, tissue capacity or other regions of the kinetic chain.
Interpretation is stronger when paired with throwing history, workload, shoulder ROM, rotator cuff strength, scapular assessment, trunk and hip findings, and functional throwing progression.
The Hara Test is an 11-part shoulder assessment mainly used with baseball players who have throwing-related shoulder issues.
Research suggests that lower scores may be linked with shoulder pain and difficulty throwing.
A score of 8 or less out of 11 may suggest the player is more likely to have throwing-related shoulder pain.
A score of 7 or less out of 11 may suggest the player may be unable to throw properly and should be assessed further.
However, there is currently limited research showing the exact sensitivity, specificity, or diagnostic accuracy of the full Hara Test.
So, the Hara Test is best used as part of a broader shoulder assessment, rather than as a stand-alone diagnostic test.
Current overhead athlete literature supports full kinetic chain assessment because the lower extremity, trunk and scapular region contribute to throwing and serving mechanics.
Reliability depends on the exact items used, examiner consistency, measurement tools, fatigue state and how abnormal findings are defined.
Because the Hara Test contains multiple items, repeatability improves when each item is recorded separately rather than using only a broad positive or negative result.
Common errors include treating the Hara Test as diagnostic, not recording item-level results, failing to compare sides, ignoring throwing workload, not assessing the trunk or lower limb, and overinterpreting one abnormal item.
Limitations include variable test versions, limited current diagnostic accuracy evidence, sport-specific adaptation and dependence on examiner skill.
Use the Hara Test to identify shoulder and kinetic chain findings that may guide further testing, exercise programming and throwing progression. It is especially useful when findings are tracked over time and connected to workload and symptoms.
Record test name, version used, item-level findings, side tested, pain score, symptom location, mobility restrictions, strength deficits, scapular findings, compensation, throwing symptom relevance, confidence in result and follow-up tests required.
Add related shoulder ROM, rotator cuff strength, thoracic rotation, hip ROM, trunk control, workload, pitch count and return-to-throwing notes where relevant.

Throwing Assessment
It screens multiple shoulder, scapular and upper-limb kinetic chain findings relevant to throwing athletes.
No. It is a screening tool, not a diagnostic test for a specific injury.
It is most useful for throwing and overhead athletes.
Record each item separately, including side, pain, mobility, strength, scapular findings and compensation.
No. Throwing readiness also depends on symptoms, workload, strength, ROM, mechanics and graded exposure.
The Hara Test is a structured throwing shoulder screen.
It should be recorded item by item.
It does not diagnose a specific injury.
Whole kinetic chain assessment is important in throwers.
Measurz should capture item-level findings, symptoms and follow-up tests.
