CIRS Functional Capacity Evaluation & Work Simulation 1 — Questions and Answers
Question 1: What is the PRIMARY purpose of a Functional Capacity Evaluation (FCE) in industrial rehabilitation?
- To diagnose a worker's underlying medical condition
- To prescribe pharmacological pain management strategies
- To objectively measure a worker's physical abilities relative to job demands (Correct answer)
- To assess a worker's psychological readiness for return to work
Correct answer: To objectively measure a worker's physical abilities relative to job demands
An FCE objectively measures a worker's physical functional abilities and compares them to the specific demands of their job, guiding safe return-to-work decisions.
Question 2: Which validity indicator during FCE grip strength testing most reliably distinguishes maximum voluntary effort from submaximal effort?
- Visual Analog Scale (VAS) pain rating during the test
- Coefficient of variation (CV) below 15% across repeated trials (Correct answer)
- Worker's self-reported effort level on a 0–10 scale
- Time to fatigue on a sustained static grip hold
Correct answer: Coefficient of variation (CV) below 15% across repeated trials
A coefficient of variation below 15% across repeated grip strength trials is generally accepted as indicative of consistent, maximum voluntary effort by the examinee.
Question 3: According to the Dictionary of Occupational Titles (DOT), 'Medium' work requires lifting a maximum of how many pounds occasionally?
- 20 pounds
- 35 pounds
- 50 pounds (Correct answer)
- 100 pounds
Correct answer: 50 pounds
The DOT classifies Medium work as requiring a maximum lift of 50 pounds occasionally and frequent lifting or carrying of up to 25 pounds.
Question 4: A positional tolerance test during an FCE is PRIMARILY designed to evaluate a worker's ability to:
- Coordinate fine motor movements during assembly tasks
- Maintain static postures such as sitting, standing, or kneeling over time (Correct answer)
- Perform progressive lifting from floor to overhead in sequence
- Demonstrate cardiovascular endurance during sustained dynamic activity
Correct answer: Maintain static postures such as sitting, standing, or kneeling over time
Positional tolerance tests measure how long a worker can sustain specific static postures required by their job, such as prolonged sitting at a workstation or sustained standing.
Question 5: The Isernhagen Work Systems (IWS) FCE protocol is notable because its test criteria are based on which classification framework?
- ICD-10-CM musculoskeletal diagnostic categories
- Dictionary of Occupational Titles (DOT) physical demand levels (Correct answer)
- ADA essential functions determination framework
- OSHA recordable injury severity criteria
Correct answer: Dictionary of Occupational Titles (DOT) physical demand levels
The IWS FCE was developed using Dictionary of Occupational Titles (DOT) physical demand level criteria, allowing evaluators to directly compare worker abilities to standardized occupational demands.
Question 6: In an FCE report, the term 'safe maximum' refers to the:
- OSHA-mandated weight limit established for the worker's specific industry
- Highest level of physical activity a worker can sustain without undue risk of re-injury (Correct answer)
- Worker's self-reported comfortable maximum effort during testing
- Maximum functional level prescribed by the treating physician prior to the evaluation
Correct answer: Highest level of physical activity a worker can sustain without undue risk of re-injury
The safe maximum is the evaluator's clinical determination of the highest functional level the worker can perform without risking further injury, based on test performance and clinical judgment.
Question 7: During Jamar dynamometer grip strength testing, which handle position response pattern is most consistent with genuine maximum voluntary effort?
- Peak force at position 1 with linearly decreasing force at each subsequent position
- A bell-shaped curve with peak force at the second or third handle position (Correct answer)
- Uniformly high and nearly identical force across all five handle positions
- Random variation with no discernible pattern across the five positions
Correct answer: A bell-shaped curve with peak force at the second or third handle position
Biomechanical research supports a bell-shaped curve peaking at handle positions 2 or 3 as characteristic of maximum voluntary effort due to the length-tension relationship of the finger flexors.
