History - 3 Major Areas

• Workers Compensation

• Social Security

• Employment Selection

Page 11: Industrial Rehabilitation

History: Workers’ Compensation

• Early 1900’s - trend toward awareness of rehab of physically disabled

• Prior to 1910 the only recourse to bring a suit against their employers in court to claim damages for work related injuries

Page 12: Industrial Rehabilitation

Workers’ Compensation Law• Early 1900’s increasing number of claims

being settled in favor of plaintiff but many did not have resources to go to trial

• only 6% workers received financial relief

• employers risk of liability in isolated cases was astronomical - out of business in single claim

Page 13: Industrial Rehabilitation

History - Workers’ Compensation

• State Workers Compensation Law– 1910 New York – 1911 Wisconsin

• mandated employer-financed insurance programs• created a “no fault system” where workers gave up

right to sue and employers accepted limited liability• purpose was prevention of poverty, not disability

prevention

Page 14: Industrial Rehabilitation

Workers’ Compensation Law

• varies from state to state

• costs are paid by employer to state fund or insurer

• each state determines specific benefits received

Page 15: Industrial Rehabilitation

History: Workers’ Compensation• By 1920, 42 out of 48 states & DC had WC laws• has been called the “most dramatic event in 20th

century of American civil justice”*• for 25 years was the only social disability income

program in the US

*Darling-Hammond L, Keisner TJ: The law and economics of workers’ compensation, Santa Monica CA, 1980, Rand Publications.

Page 16: Industrial Rehabilitation

Understanding Workers Comp

• Who pays and why?– Every employer except

• family business, only family employees

• self-insured

– Point is to spread risk• riskier industries pay more

• higher injury rates pay more

Page 17: Industrial Rehabilitation

Who is Covered

• Everyone except– Baby-sitters– Temporary agriculture– Religious school teaching– Part-time domestic help– Family members in family business

Page 18: Industrial Rehabilitation

What is Covered?

• Work-related injuries or illnesses– must “arise out of and in the course of

employment

• Includes– organized recreational functions– travel– homework– unauthorized presence in workplace

Page 19: Industrial Rehabilitation

Pre-existing Conditions: Pre-disposing to Injury

• If it occurs at work, it arises out of employment as far as the law is concerned

• does not matter if the injury occurs during an activity that would not have been injurious but for the preexisting sensitivity

• Employers must “take employees as they find them”

Page 20: Industrial Rehabilitation

Pre-existing Conditions: Causing Injury

• When cause is unclear, law will not attribute it to work unless evidence points in that direction

• King v. TTC Illinois Inc., Montana, 2000– Truck driver, smoker, HBP, high cholesterol– died in cab of truck after handling tarps– medical examiner concluded death caused by

preexisting heart condition– court sided with med examiner

Page 21: Industrial Rehabilitation

History - Workers’ Compensation

• 1920’s saw decline in the workers compensation system

• Disputes arose over whether injuries were work-related and the extent of disability

• By mid-1930’s debate began over whether to add disability to the social security system

Page 22: Industrial Rehabilitation

History: Social Security Disability

• Social Security system added disability coverage in increments:

– ‘54 disabled exempt from making social security payments– ‘56 disability benefits began for those between 50 and 65 were

unable to work due to disability– ‘58 monthly benefits paid to dependents– ‘60 age limitation of 50 years removed– ‘65 12-month requirement added– ‘72 benefits increased & Medicare benefits available to those

whose disability lasted for at least 2 years

Page 23: Industrial Rehabilitation

SSA’s Definition of Disability

• The inability to do any substantial gainful activity (SGA) by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.

Page 24: Industrial Rehabilitation

SSA’s Definition of Disability

• Impairment must be so severe that person is not only unable to do past work but considering age, education, and work experience engage in any other substantial gainful work which exists in the national economy

Page 25: Industrial Rehabilitation

Five Step SSA Disability Determination Process

• Is the individual engaged in SGA?

• Does the individual have a severe impairment?

• Does the impairment meet the listings?

• Can the individual do past relevant work?

• Can the individual do other work?

Page 26: Industrial Rehabilitation

History - Rehabilitation

• World War I - disabled veterans’ vocational needs

• 1920 - Passage of Vocational Rehab Act - Provided funds for vocational rehab– veterans WWI– industrially injured

• Amendments in 1943 & 1954

Page 27: Industrial Rehabilitation

History - Employment Selection• Americans with Disabilities Act (ADA)

July 26,1992– extended legal protection from employment

discrimination to handicapped Americans– goes beyond traditional equal employment law

and affirmative action by requiring individualized treatment on a better-than-equal basis

– tests cannot be used to screen out disabled individuals unless they are job-related

Page 28: Industrial Rehabilitation

ADA

• All employers of 15 or more people• protects “qualified persons with a disability”

– physical or mental impairment substantially limits one or more major life activities

• “record of”• “regarded as having”

– has requisite skills, experience, education, & other job-related requirements

– able to perform essential functions with or without reasonable accommodations

Page 29: Industrial Rehabilitation

ADA - Substantial Limitation of Major Life Activity

– Caring for self– Performing manual tasks– Walking – Seeing – Hearing– Speaking– Breathing– Learning– Working– Participating in community affairs

Page 30: Industrial Rehabilitation

ADA - Essential Functions

• Job function considered essential if:– reason job exists is to perform function– limited number of employees available

among whom performance of function can be distributed

– highly specialized so that the incumbent is hired for the ability to perform the function

Page 31: Industrial Rehabilitation

ADA - Reasonable Accommodations

• modifications or adjustments to job to enable impaired person to enjoy equal employment– job application process– work environment– benefits & privileges

Page 32: Industrial Rehabilitation

ADA - Undue hardship

• If necessary modifications create “undue hardship” employer does not have to provide

• Factors considered:– nature and cost– financial resources of employer– effect on the operation of the facilities/business

Page 33: Industrial Rehabilitation

History - Injury Prevention• Williams-Steiger Occupational Safety & Health

Act 1970– assure safe and healthful working conditions for men

and women– no specific ergonomic standards– ergonomic considerations covered under the general

duty clause• employers responsible for furnishing employees a place of

employment free from recognized hazards that are likely to cause death or serious physical harm to employees

Page 34: Industrial Rehabilitation

OSHA

• Regulatory body

• Employers of 11 or more people

• Reduce hazards/comply with standards

• Conducts inspections

• Issues fines

• No ergonomic standards per se

Page 35: Industrial Rehabilitation

History - Injury Prevention• 1991 - OSHA published “Ergonomics

Program Management for Meatpacking Plants” covering primary components of an effective ergonomics program:

• Worksite Analysis– Hazard Prevention & Control– Medical Management– Training & education

Page 36: Industrial Rehabilitation

NIOSH• set up by same act that established OSHA• directed by Secretary of Health & Human

Services• authorized to develop standards & conduct

research• Work Practices Guide for Manual Lifting

including formula for calculating recommended weight limit for lifting tasks

Page 37: Industrial Rehabilitation

Governmental agencies

• Department of Labor– description/classification of work

• Social Security Administration– disability determination

• NIOSH– research

• OSHA – regulatory

The BIG PICTURE...

• Continuum of Care– Medical Model vs Work Recovery Model– Acute, Subacute, Chronic

• medical management

• work recovery management

• Role of assessment

• Importance of function

Page 40: Industrial Rehabilitation

Continuum of Care• Medical Model

– Acute

– Sub-acute

– Chronic

• Work Recovery Model– Off Work

– Transitional modified duty

– Return to full duty

– Permanent modified duty

– New permanent position

– Disability

Page 41: Industrial Rehabilitation

Acute Care: Medical Side

• Acute– promote healing of tissue– minimize symptoms– maximize function

• Important to begin asking about job tasks and demands early!– usually patient or employer self-report– can explore occupational information

• DOT• Job Exploration Software

Page 42: Industrial Rehabilitation

Work Related Function

• Early emphasis on work-related function is one of the hallmarks of a holistic clinician!

Page 43: Industrial Rehabilitation

Acute Care: Work Recovery

• Acute- Off work – Begin by asking about home function– Be specific

• activity• duration

– performing functional activities at home• sitting• standing• walking• lying• light materials handling

Page 44: Industrial Rehabilitation

Acute Care: Work Recovery• Aim for graded progression of home function• Scheduled and structured• As a measure of outcome• Set stage for

– problem solving

– pain management• exercise

• positioning

Page 45: Industrial Rehabilitation

Work Function

• Based on demands of job– Work simulation– Work conditioning exercises– Graded with specific goals

Page 46: Industrial Rehabilitation

Acute Care: Work Recovery

• Acute -Transitional modified work– original job– new temporary job

• meaningful work is optimal

– guided by functional testing– communication with supervisory personnel is

essential– progression

Page 47: Industrial Rehabilitation

Importance of Function• Only way we have of knowing whether we

are making a significant difference in the lives of the patients we treat is to find out about function of patient & work demands

– self-report• accuracy

• motivation

– observational measurement is preferable

Page 48: Industrial Rehabilitation

Importance of Work-Related Functional Assessment

• Only objective means of determining whether patient abilities meet functional demands of work is to evaluate– asking patient to perform functional task– measuring physical demands of work– match?

• yes return to work• no further treatment or modified

work

Page 49: Industrial Rehabilitation

Appropriate Measurement for the Acute Stage

• Not full blown FCE• Not formal job demands analysis• Instead:

– informal visit to the job site– observe the job– use the information to develop a brief screen of

the most demanding aspects of the job

Page 50: Industrial Rehabilitation

What does the informal job site visit accomplish?

• Increases your – comfort level with the industrial environment– credibility in the eyes of your patient– patients’ level of trust– ability to market other industrial services– value in the scheme of treatment

• physicians• case managers

Page 51: Industrial Rehabilitation

To maximize effectiveness in treating work-related injuries -get out of the clinic and into the

work place!

Page 52: Industrial Rehabilitation

Acute Management• Hands-on does not preclude patient

participation– Self mobilization

– Home program

– Home administration of modalities

– Home positioning

– Functional activity

• Patient should have goals related to function

Page 53: Industrial Rehabilitation

Example: Home Program for Acute Back Patient

– Spend five 20-minute sessions in side lying with towel roll between iliac crest and rib cage

– Perform 10 reps of extension exercise every hour

– Apply ice pack for 20 minutes twice a day

– Walk for 15 minutes 5 times per day

– Stand for 15 minutes 5 times per day

– Perform 10 reps of stretching exercises 2 times per day

Page 54: Industrial Rehabilitation

What Don’t Want...• Inactivity!• Unstructured daily regimen

Because...• promotes the sick role • encourages

– Disuse atrophy

– De-conditioning

– Decreased mobility

Page 55: Industrial Rehabilitation

Essential Elements of Success

• Program should be regimented with patient keeping a home program log

• Set specific measurable goals• Begin return to work/modified work

discussions early• Demonstrate interest and knowledge

regarding functional/work activities

Page 56: Industrial Rehabilitation

Knowledge of Work-Related Function

• Therapist knowledge regarding work function – creates face validity for worker– builds trust– improves quality of treatment

• work simulation• work conditioning• transitional duty

Page 57: Industrial Rehabilitation

Subacute: Medical Management

• Subacute - Shift toward more– work simulation– work conditioning– work recovery/transitional duty– posture/body mechanics training– functional testing

By the end of the sub-acute phase, should know whether the patient can return to former work.

Page 58: Industrial Rehabilitation

Subacute: Work Recovery• Transitional modified duty

– duration increases

– duties increase

• Work conditioning– job specific

– strengthen, stretching, endurance

• Work simulation– to assist with progression to next stage of

transitional work/full duty

Page 59: Industrial Rehabilitation

Chronic: Medical Management

• Shifts more toward

– pain management– psychological interventions– coping with residual functional capacity

Page 60: Industrial Rehabilitation

Chronic: Work Recovery

• Former job with modifications

• Placement in same line of work, different job– same employer– different employer

• Vocational assessment, exploration, counseling, retraining for new work

Pre-Work Screens

Page 62: Industrial Rehabilitation

Traditional Return-to-WorkDisability Decision-Making

• Client self-report• Do you think you are ready to go back to work?• Do you think you are able to work?

• Impairment/diagnosis-based decision

• Imaging studies

• Range of motion

• General impressions

No objective information regarding job

demands or patients’ functional abilities

Page 63: Industrial Rehabilitation

The Well-Designed FCE• Comprehensive • Standardized Yet Flexible• Clear Report Format• Safe• Practical • Objective• Reliable• Valid

Page 64: Industrial Rehabilitation

Comprehensive• Covers all physical demands

defined by DOL in the Dictionary of Occupational Titles

• Does not focus exclusively on materials handling

Page 65: Industrial Rehabilitation

Standardized Yet Flexible• Procedures• Equipment• Verbal Instructions• Scoring System

• Ability to chose individual items for job-specific testing

Page 66: Industrial Rehabilitation

A Clear FCE Report

• Overall level of work (Sedentary, Light, Medium, Heavy, Very Heavy)

• Percent of day individual demands can be performed (Constantly, Frequently, Occasionally, Never)

• Tolerance for the 8 hour day FCEFCESummarySummary

ReportReport

Page 67: Industrial Rehabilitation

A Clear FCE Report

• # of tasks with self-limiting behavior• Inconsistencies in performance• Interpretations/Conclusions

– Major areas of dysfunction– Factors underlying limitations– Discrepancy between job demands & pt abilities

• If indicated:• Job Specific Testing• Job/Occupation Comparisons• Recommendations

Page 68: Industrial Rehabilitation

Safe• Minimize chance of injury during

FCE– Heart rate monitor

– Allow patient to stop if need arises

– Therapist observing body mechanics/alignment

– Well-defined safe stopping points

– Clear contraindications and pre-cautions

Page 69: Industrial Rehabilitation

Objective Projections• Minimize clinical “guesswork”

• Projecting to 8-hour day

What is Reliability?

• Reliability = Consistency

• If different therapists administer an FCE to the same patient, will they obtain the same results?

Page 73: Industrial Rehabilitation

What is Validity?

• Validity = Accuracy

• Can the FCE accurately predict a safe maximum level of work?

Reliability and validity are criticalReliability and validity are criticalto to trustingtrusting FCE results! FCE results!

Page 74: Industrial Rehabilitation

Why Are Reliability and Validity Important?

• Without proven reliability and validity, you and the patient do not know if test results are accurate

• Legal defensibility: Daubert v. Merrill Dow Pharmaceuticals 1993 Supreme Court Ruling

If testimony does not meet standards FCE results may be considered inadmissible

Page 75: Industrial Rehabilitation

Reliability and Validity of FCE

• Smith et al: Am J Occup Ther, 1986

• Dusik et al: J Occup Med, 1993

• Saunders et al. Physical Therapy, 1997

• Alpert et al. J Occup Rehab, 1991

• Matheson et al. Spine, 1995

Page 76: Industrial Rehabilitation

Summary of Research

• All of these studies made important contributions to the literature

• However, limitations include:– Many studies focused primarily on the manual

materials handling aspect of FCE– Many studies addressed either reliability or

validity but not both– Methodological flaws with several of the

studies

Page 77: Industrial Rehabilitation

Interrater Reliability and Concurrent Validity

Lechner et al: Journal of Occupational Medicine, 1994

• Two therapists evaluated the same 50 patients for reliability using a new FCE protocol, Physical Work Performance Evaluation (PWPE)

• Concurrent validity: PWPE (FCE) predictions were compared to actual work status

Page 78: Industrial Rehabilitation

Predictive ValidityLechner, Page, Sheffield: (abstract) Physical

Therapy 1996

• Study conducted at Baptist Medical Center Montclair, Birmingham, AL

• 30 Workers Compensation patients who were admitted to a interdisciplinary work hardening program using PWPE (FCE) protocol

• Compared PWPE recommendations to actual return to work level

Page 80: Industrial Rehabilitation

Predictive Validity• Recommendations based on discharge

PWPE:• RTW - full duty

• RTW - modified duty

• No RTW

• Substantial agreement between recommendations and:

• Initial RTW Kappa of .74

• 3 month follow up Kappa of .69

• 6 month follow up Kappa of .71

Page 81: Industrial Rehabilitation

Contributions of PWPE Research

• These studies are the only ones that have examined both reliability and validity of a comprehensive test published in the peer-reviewed medical literature

Page 82: Industrial Rehabilitation

Common Misuse of FCE

Page 83: Industrial Rehabilitation

“Can’t Catch the Faker, Why Not? ”

• Many of the traditional tests used to “catch the faker” have not been adequately researched

• It is impossible to infer motivation from these tests, in a legally defensible way

• Clinicians who are marketing their services and making this claim are misrepresenting themselves

Page 84: Industrial Rehabilitation

Sincerity of EffortAny statement that implies decreased

motivation

• “symptom magnification”• “exaggerated pain behavior”• “invalid or conditionally valid FCE”• “malingerer”

Page 85: Industrial Rehabilitation

Sincerity of Effort“Measures” typically used to justify statements about

sincerity of effort

• Coefficient of Variation (CV, COV)

• Waddell’s Non-Organic Signs (NOS)

• Bell-shaped curve

• Rapid exchange grip

• Correlation of heart rate to pain scores

• Correlation of pain scale to behavior

• Correlation of impairment measures (ROM, MMT, etc.) to function

• “Validity scales”

Page 86: Industrial Rehabilitation

Sincerity of Effort

If any of these measures are used to justify accusations of a lack of sincere effort or motivation…

Problem: Research supporting the reliability and validity if

these protocols for the purpose of detecting sincerity of effort/motivation is lacking…not defensible

Page 87: Industrial Rehabilitation

The Good News

• We can document self-limiting behavior (stopping before maximum effort is reached)

• We know the extent of self-limiting behavior in motivated patients

• We can document inconsistent performance• New research-based protocols becoming available

that allow us to link inconsistencies with non-compliance

• We can document atypical performance

Page 88: Industrial Rehabilitation

Sincerity of Effort

Test results need to be expressed very carefully

• “Patient self-limited on…”

• “Patient demonstrated the following functional inconsistencies”

• “Patient’s test results were similar to a research group who were instructed to intentionally withhold.”

Page 89: Industrial Rehabilitation

The Challenge

• To distinguish between appropriate and inappropriate tests of sincerity of effort

• Not overstate test results and increase exposure to litigation

Page 90: Industrial Rehabilitation

Additional InformationLechner et al. Detecting Sincerity of Effort :

A Summary of Methods and Approaches. Physical Therapy, July 1998.

• Review article: Discusses in detail the problems with commonly utilized methods for evaluating sincerity effort.

Page 91: Industrial Rehabilitation

Additional InformationSchapmire et al: Simultaneous Bilateral Testing:

Validation of a New Protocol to Detect Insincere Effort During Grip and Pinch Strength Testing. Journal of Hand Therapy, Vol 15, No. 3.

• Research supporting new sincerity of effort testing.

Page 92: Industrial Rehabilitation

What Is Job Demands Analysis?

• Job Demands Analysis defines:

– essential functions or tasks of the job– physical demands of those functions– percent of day spent performing the physical

demands– forces being exerted – environmental conditions– equipment used

Page 93: Industrial Rehabilitation

Difference Between JDA and Hazard Identification

• JDA– defines the essential physical demands of the job

• Hazard Identification– identifies physical demands that exceed safe

limits

Can the two overlap? Yes, one can lead to the other but need to know the employer’s purpose for analysis.

Page 94: Industrial Rehabilitation

How are the Results of Job Demands Analysis Used?

• ADA job descriptions

• Pre-Work screening

• Transitional duty

• Return-to-work decisions

• Setting pay rates

Matching worker abilities to job demands!

Page 95: Industrial Rehabilitation

The Importance of Job Classification

• Report the results of JDA by using a classification system defined by the DOL

• Provide additional information– Climbing (stairs & ladder)– Reaching (Overhead & forward)– Lifting (above vs. below waist)

Page 96: Industrial Rehabilitation

Classification of Job Demands • Defined in DOT, SCO, & COJ• Classifies manual materials handling demands:

Occasional Frequent (50%) Constant (20%)

– Very Heavy > 100 lb.> 50 > 20– Heavy 51 - 100 lb. 25 - 50 10 - 20– Medium 21 - 50 lb. 10 -25 1 - 10– Light 11-20 lb. 1 - 10 *– Sedentary 1 -10 lb. * *

* negligible weight

Page 97: Industrial Rehabilitation

Classification of Physical Job Demands

• Non-materials handling demands

– standing

– walking

– sitting

– reaching

– crouching

– stooping

– kneeling

– crawling

– climbing

– handling

– fingering

– balancing

Page 98: Industrial Rehabilitation

Classification of Physical Job Demands

• Non-materials handling tasks classified according to duration of demand within the work day

– Constantly 2/3 to the full day– Frequently 1/3 to 2/3 of day– Occasionally up to 1/3 of day– Never not required

Page 99: Industrial Rehabilitation

Classification of Physical Job Demands

• Dexterity Demands

– classified as an aptitude by the DOT– Rated on a 1 -5 scale

• 1 = top 10% of population

• 2 = highest 1/3, exclusive of top 10%

• 3 = middle 1/3

• 4 = lowest 1/3, exclusive of bottom 10%

• 5 = lowest 10% of population

Page 100: Industrial Rehabilitation

Classification of Physical Job Demands

• Two types of dexterity

– Manual:• “Ability to move hands easily and skillfully. To

work with hands in placing and turning.”

– Finger:• “Ability to move fingers and manipulate small

objects with fingers, rapidly or accurately.”

Page 101: Industrial Rehabilitation

Classification of Physical Job Demands

• Shortcomings with DOT classification system:– Very general

• climbing - ? ladder Vs stairs• reaching - ? overhead, forward, backward

– Categories very broad• 1/3 to 2/3 of day• 21 - 50 lb.

Page 102: Industrial Rehabilitation

Reliability

• Pilot studies showed that when therapists perform JDA without a structured format, it was not very reliable

• Two therapists analyzing the same job had different results

• REQUIRES STANDARDIZED PROCESS TO ACHIEVE CONSISTENCY AND ACCURACY

Page 103: Industrial Rehabilitation

Basic Steps of Job Analysis

• Determine the tasks of the job

• Determine the frequency & duration of each task

• Determine % day task is performed

• Observe/videotape the tasks

• Measure forces and distances

Page 104: Industrial Rehabilitation

Basic Steps of Job Analysis

• Determine the percent of task each demand is performed

• Determine the adjusted percent of day each demand is performed by:– multiplying the task % x demand %

• Sum the adjusted percentages to determine the total percent of day each demand is performed

Page 105: Industrial Rehabilitation

Basic Steps of Job Analysis• Translate the % into:

– Constantly– Frequently– Occasionally– Never

• Determine the highest weight/force handled for each type of lift to classify the job Sed to V. Heavy

Page 106: Industrial Rehabilitation

Contents of Report• Tasks • Environment• Tools/equipment• Protective equipment• Overall level of work• Percent of day performing each demand

– C,F,O,N• Force demands• Distance over which forces applied

Page 107: Industrial Rehabilitation

Optional Aspects of Report

• Comparisons to patient abilities• Recommendations for transitional duty• Recommendations for post-offer screening• Areas for further hazard assessment

Selection of these components will depend on what the employer wants.

Three MUSTS for Preemployment Screening

• JOB RELATED JOB RELATED JOB RELATED!

• DOCUMENT DOCUMENT DOCUMENT!

• FOLLOW-UP FOLLOW-UP FOLLOW-UP!

Page 112: Industrial Rehabilitation

Important Considerations

Americans with Disabilities Act

(ADA)

Test only the essential

functions of the job!

Page 113: Industrial Rehabilitation

Optimal Sequence

• Interview

• Conditional offer

• Post-offer/ screen

– medical screen

– physical abilities testing

– drug screening

Page 114: Industrial Rehabilitation

Traps to AVOID!• Pre-offer testing

• Predicting future injury

• General strength testing

• Making comparisons to normative data

• Adverse impact

ADAADA EEOCEEOC

Page 115: Industrial Rehabilitation

PROBLEMS with Pre-Offer Tests

Safety Issues• Cannot perform medical screening• Cannot monitor physiological responses to

testing

Page 116: Industrial Rehabilitation

PROBLEMS with Pre-Offer Testing

• As a health care professional, your pre-offer exam may be considered medical just because it was administered by a health professional

Page 117: Industrial Rehabilitation

Predicting Future Injury

Consensus among the medico-legal community:

Virtually impossible to deny employment based on pre-offer testing that predicts future injury

Page 118: Industrial Rehabilitation

Predicting Injury• Based on speculation• Applicant perceived as person with a disability

Must make reasonable accommodation

PROBLEMS! LITIGATION!

Page 119: Industrial Rehabilitation

INSTEAD...

DETERMINE WHETHER PHYSICAL ABILITIES MEET JOB DEMANDS

AVOID PROBLEMS!

AVOID LITIGATION

Page 120: Industrial Rehabilitation

Avoid Causing Adverse Impact

• Adverse impact

– selection rate for any race, sex, or ethnic group less than 80% of rate for the group with the highest selection rate.

Page 121: Industrial Rehabilitation

Example of Adverse Impact

• Example:

– 60% of male applicants pass post-offer screen but only 15% of female applicants pass (.15 /.60 = .25)

– Considered adverse impact: the pass rate for women is only 25% of the pass rate for men.

Page 122: Industrial Rehabilitation

General Strength Testing

Faculty at Washington University; Dueker JA, Ritchie SM, Knox TJ, Rose SJ in JOM, Jan ‘94:

“isokinetic trunk evaluation was of no value in employee selection”

Page 123: Industrial Rehabilitation

General Strength Testing

Faculty from the Department of Orthopaedic Surgery, Glasgow, Scotland; Newton M & Waddell G in Spine ‘93:

“...inadequate scientific evidence

to support the use of iso-machines in pre-employment screening ...or medico legal evaluation.”

Page 124: Industrial Rehabilitation
