How this service works
Verheyden 2004 original Trunk Impairment Scale from caller-assigned static sitting balance 0-7, dynamic sitting balance 0-10, and coordination 0-6 (max 23). If static sitting balance is 0, the total is 0. magent does not examine sitting balance or copy the item list. Not TIS 2.0, not Fujiwara 2004, and not a severity band.
Output
Returns the computed TIS total score (integer 0–23) per the Verheyden 2004 original algorithm. If static sitting balance is 0, the total is forced to 0 regardless of other subscale values.
Example use cases
Stroke rehab TIS documentation
“My stroke patient scored 6 on static sitting balance, 8 on dynamic sitting balance, and 5 on coordination — what's their Verheyden 2004 TIS total?”
Zero static balance edge case check
“If a patient has a static sitting balance score of 0, a dynamic sitting balance of 4, and a coordination score of 3, what is their original TIS total under Verheyden 2004?”
Clinical trial data entry scoring
“I need the original Trunk Impairment Scale totals for a trial participant: static sitting balance 3, dynamic sitting balance 6, coordination 2 — give me the Verheyden 2004 score.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/trunk_impairmentWhen to prefer
Use this endpoint when you need the original Verheyden 2004 TIS total (max 23) computed from discrete subscale scores. Do not use this for TIS 2.0, Fujiwara 2004, or any severity banding — those are different instruments. Ideal when an agent already has the three subscale scores and needs the validated arithmetic total for charting, clinical trials, or rehab documentation.
Side effects
- Missing required query parameter (static_sitting_balance, dynamic_sitting_balance, or coordination) returns an error
- Subscale value outside permitted enum range (e.g. coordination > 6) returns a validation error
- Non-integer or string values for subscale parameters return a schema validation error
