Cumulative Trauma Disorder Risk Screening Point Scorer

Independent CTD observed factor presence and explicitly caller weights, no medical diagnosis or invented validated screening scale. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.

Description

A cumulative-trauma screen summarizes independently annotated indicators with supplied point weights.

A cumulative-trauma screen summarizes independently annotated indicators with supplied point weights.^[1]

Its unresolved point allowance preserves missing evidence without providing a diagnosis or validated clinical scale. Use this tool to calculate cumulative Trauma Disorder Risk Screening Point Scorer from the supplied measurements and assumptions.

When to use Cumulative Trauma Disorder Risk Screening Point Scorer

Use this tool to calculate cumulative Trauma Disorder Risk Screening Point Scorer from the supplied measurements and assumptions. Establish the observation protocol, units, task and reference population or review criterion before entering measurements.

How to use Cumulative Trauma Disorder Risk Screening Point Scorer and understand its results

Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
Enter observedCtdScreenFlags, knownCtdScreenFlags, callerCtdScreenPointWeights, using the field meanings and rules below, then run the tool.
Read knownScreenPoints, unassessedMaximumAdditionalPoints. Interpret the fields using their units, signs and evidence conventions below.
If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.

Input field	Meaning	Value type	Requirement
observedCtdScreenFlags	Observed ctd screen flags; binary 0/1 under the definitions below	list of number	Required
knownCtdScreenFlags	Known ctd screen flags; binary 1=known, 0=unknown, in the order described below	list of number	Required
callerCtdScreenPointWeights	Caller ctd screen point weights	list of number	Required

Enter nonempty aligned binary indicator flags and known flags with nonnegative point weights. Sum weight×indicator only where known=1; separately sum weights where known=0 as maximum additional unresolved points. Unknown indicator placeholders do not contribute to the known score. All-zero weights are allowed; no risk band, diagnosis or validated default questionnaire is installed.

knownPoints=Σknown_i×observed_i×weight_i; unresolvedMaximum=Σ(1−known_i)×weight_i

Use the exact units, boundary rules, ordering and missing-evidence conventions above.

Output field	Meaning	Value type
knownScreenPoints	Known Screen Points; follow the units, sign, ordering and evidence convention stated above	number
unassessedMaximumAdditionalPoints	Unassessed Maximum Additional Points; follow the units, sign, ordering and evidence convention stated above	number

Limitations and assumptions

Its unresolved point allowance preserves missing evidence without providing a diagnosis or validated clinical scale. Interpretation depends on the units, sampling scope and exact model described above.

All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.

Alternative or Complementary methods

Use Laptop-only Posture Risk Score Quick Rater for this related task: A posture screen can sum weights for independently observed indicators.

Use Mouse Elbow Anchored Movement Risk Flag Checker when its separate inputs and assumptions fit the question: Mouse-use evidence can be compared with explicitly supplied screening classes.
