HUHN and ROBERT V. VOLSKI Business and industry are interested in reducing their direct and indirect costs of health services. The answer to reducing these costs for many companies has been to shift their emphasis from subsidizing sickness to promoting health and welfare in wellness, prevention, or fitness programs. Basic certification courses have been developed at a graduate level for fitness instructors, exercise test technologists, exercise leaders, and directors of preventive programs. These courses are open to a broad range of disciplines, including physical therapy. Physical therapists can perform different roles in industrial preventive programs to prevent on-the-job injuries and improve physical fitness. Physical therapists have both the education and the clinical experience to be effective in planning preventive programs. We have divided the comprehensive preventive exercise program into five phases: history questionnaire, evaluation, consultation, performance, and progress assessment. These phases, especially the evaluation of the patient, are discussed from the perspective of the contribution the physical therapist can make. The characteristics of successful company-sponsored exercise programs also are discussed. Key Words: Exercise therapy, Heart diseases, Industry, Physical therapy, Preventive health. General Motors in 1976 made headlines by spending more money on employee health benefits than on steel. Over the last decade, business and industry have given increasing attention to these rising health care costs. Estimates published in 1982 have placed the national price tag on health care at $470 billion. Of this, business annually pays approximately $170 billion, or about one third.1 Coronary heart disease and back pain create an appalling cost in lives, lost wages, disability, and lost productivity. Xerox Corporation estimates that its replacement costs for high level executives who have heart disease range from $500,000 to $ 1,000,000 a person in compensation and training costs. Back pain affects 75 million workers and accounts for $1 billion in lost output and $250 million in workmen's compensation claims annually.2 Business and industry, therefore, are interested in reducing their direct and indirect costs of health services. Direct costs include health, workmen's compensation, disability, and life insurance premiums. Indirect costs that are less noticeable and more difficult to quantify include absenteeism, lost productivity, poor job performance, employee turnover, and poor morale. The answer to reducing these costs for many companies has been to shift their emphasis from subsidizing sickness to promoting health and welfare in wellness, prevention, or fitness programs. In theory, some differences exist between the concepts of prevention, wellness, and fitness. Prevention deals with discouraging negative behavior such as smoking, poor eating habits, and lack of exercise. Wellness stresses the positive aspects of life style change, including the joy of living. Fitness programs emphasize exercise participation and the Mr. Huhn owns and directs Human Performance Center, 411 W Pueblo St, Santa Barbara, CA 93105 (USA).

All concepts, however, deal with improved health through self-responsibility. BUSINESS AND INDUSTRY PREVENTIVE SERVICES Many different health services are used by business and industry. Johnston and Blakney presented a diagram of their concept of both the "preventive health phase" and "rapid response phase" of a comprehensive industrial health program.3 Jacobs and Chovil have developed a framework to assess the role of company medical programs and company operations.4 These preventive services can be placed in the broad categories of 1) medical examinations, 2) medical fitness screening, 3) exercise programs, 4) health education and change in life style courses, and 5) safety activities. Medical examinations and screening may include health risk appraisals; questionnaires regarding musculoskeletal problems; and evaluations of cardiovascular endurance,flexibility,muscle strength, body composition, pulmonary function, and blood chemistries. Health action programs include a variety of exercise programs that usually emphasize cardiovascular endurance. Health education programs often emphasize cessation of smoking, control of hypertension, positive eating habits, management of stress, abstinence from alcohol and drugs, and proper lifting and moving techniques. Throughout these courses, the positive and joyful aspects of work usually are emphasized. In 1973, only 75 major corporations had physical fitness programs. Now the Fortune 500 companies comprise a major share of the 750 companies that have physical fitness programs. More than 400 major corporations such as Xerox, Johnson and Johnson, IBM, Prudential Insurance, Control Data, Kimberly Clark, Century Insurance, Ryder Systems, and General Foods offer some type offitnessprogram.5 1840 PHYSICAL THERAPY Downloaded from http://ptjournal.apta.org/ by guest on September 11, 2014 Although large corporations have established comprehensive programs, including instructor-led in-house exercise programs, smaller corporations and businesses face financial constraints for their fitness programs. The products most readily marketable to these smaller companies are health risk profiles and educational packages. These lack the employee participation that gives increased impetus to positive life style changes. Several alternatives exist and will be discussed. Studies Several definitive studies have researched the long-term benefits of corporate wellness programs. A study of 600 employees who received a comprehensive preventive health and activity program over a five-year period showed a significant reduction in the risk of coronary artery disease, amelioration of a wide range of health problems, and a large reduction in employee absenteeism.6 Shephard et al studied 234 men and 300 women who participated in a three session a week company fitness program for one year.7 They noted the following results: significant reduction in medical reimbursement costs, decrease in absenteeism of 1.3 days for each employee, 13.5% decrease in employee turnover, and 50% reduction in employee hospitalizations. Cox et al reported the results of a Canadian Life Assurance study.8 This controlled trial measured the effects of a wellregulated employee fitness program on physiological "fitness" scores and job satisfaction, productivity, and absenteeism. The results of these studies included the following: Turnover decreased from 15% to a rate of 1.5% for a 10-month period, productivity rose 31.3% in three departments with zero turnover, average monthly absenteeism figures decreased 20% in both the test and control companies, and net maximum benefit savings accounted for approximately 1 % of the company's payroll costs, or $231,000 annually. Metropolitan Life found that 100 employees who participated in a fitness program averaged 4.8 sick days a year compared with 6.2 days a year for the members of a control group who did not exercise (Wall Street Journal, September 15, 1981, p 56). Shephard summarized the results of many programs that have looked at cost-benefit and cost-effectiveness.9 He found promising benefits to the company and the employee, including an increase in worker satisfaction, an increase in productivity, and a decrease in absenteeism and turnover. Despite these encouraging reports, sound scientific data relative to these effects have been sparse.10 In general, most employee fitness research lacks reliable control groups and leaves open the question of self-selection because this research is predominantly cross-sectional in nature. Thus, the actual value of implementing physical activity and life style programs in business and industry is yet to be established scientifically. This same question haunts the advocates of the benefits of cardiac rehabilitation programs. Wright, of the Xerox Corporation, agrees on the lack of scientific proof.11 He points out, however, that far more important justification for physical fitness programs is the multiple informal indicators. Participants and nonparticipants at all levels of the company believe that the Xerox program is cost-effective and contributes greatly to employee job satisfaction, company loyalty, and productivity. Personnel Individuals with many different backgrounds, such as exercise physiologists, physical educators, nurses, and physical therapists, are being used by business and industry to carry out roles in prevention programs. To respond to the increasing demand for personnel, major universities have developed many preventive and rehabilitative programs at the graduate level during the last five years. The American College of Sports Medicine (ACSM), Preventive and Rehabilitative Exercise Committee, has developed a directory of these programs.12 This directory presents a description of 29 programs given by the faculty members at the respective institutions. The ACSM also has developed basic certification courses for fitness instructors, exercise test technologists, exercise leaders, and program directors.13 Educational courses are held separately from the certification. The process is designed to certify basic knowledge and skills in each category. The courses are open to a broad range of disciplines, including physical therapy. The ACSM certification is required or preferred for positions in many programs. Role of Physical Therapists Physical therapists have unique professional qualities to contribute to business and industrial preventive programs. Entry-level professional education prepares physical therapists not only in normal anatomy and physiology but also emphasizes pathology and health problems. During clinical practice, these professionals commonly treat injuries and problems that could have been prevented. Exercise programs are designed and modified for problems such as sprains, strains, arthritis, bronchitis, and myocardial infarction. For individuals to use preventive techniques effectively, they must have experience with the problems they are attempting to prevent. Textbook knowledge alone is insufficient. Physical therapists have both the education and clinical experience to be effective in dealing with prevention. Preventive programs must consider both the cardiopulmonary and neuromusculoskeletal areas. Physical therapists have tended to develop expertise in specific areas. More individuals have advanced knowledge and skills in dealing with neuromusculoskeletal problems than with cardiopulmonary problems. To deal with cardiopulmonary problems effectively, an individual must have knowledge of cardiopulmonary pathology, exercise physiology, and in some cases electrocardiography. Physical therapists have sought out postgraduate educational opportunities to upgrade their proficiency. They have gained an additional knowledge base and skills in groupexercise leadership and planning exercise programs. The certified cardiopulmonary physical therapists have demonstrated a very high level of competence in all of these areas.14 Overall, physical therapists need broad backgrounds in dealing with cardiopulmonary and neuromusculoskeletal problems, or they need to pool their skills with others. Physical therapists can be used for many different roles in industrial preventive programs. Two broad areas are preventing on-the-job injuries and, therefore, workmen's compensation claims and improving physical fitness and possibly preventing disease. Their roles in either program can be categorized as consultants, educators, exercise leaders, or program directors. Volume 65 / Number 12, December 1985 Downloaded from http://ptjournal.apta.org/ by guest on September 11, 2014 1841 Some physical therapists are currently working with business and industry in preventing on-the-job injuries. As consultants, they have developed injury profiles on a specific business's workers. They have prepared profiles of the physical demands and biomechanics of specific jobs. This information has been used to develop educational presentations on injury prevention. They have also used this to train safety personnel. Other physical therapists have been involved directly as exercise leaders or program directors of company fitness programs. The role of these individuals will be described in the remainder of this article. COMPANY FITNESS PROGRAM ELEMENTS Previous discussion of the needs and benefits of preventive exercise programs left open the questions of hard scientific data. Therefore, for a preventive exercise program to be successful, upper management and the company medical director must be convinced of its value, endorse the program, and participate in it.10 Other elements that lead to a successful program include employee involvement in program planning, promotional planning, convenience, conducive environment, professional leadership, and management information systems to provide data for program evaluations. Comprehensive preventive exercise programs can be divided into five phases: history questionnaire, evaluation, consultation, performance, and progress assessment. History Questionnaire The history questionnaire ideally would contain questions regarding general health, musculoskeletal problems, exercise and physical activity, weight and eating habits, and a cardiovascular risk factor analysis, which includes stress. A health hazard appraisal questionnaire can be a part of this or a separate entity.15 This tool compares individual responders to a data base of national norms and statistical data. Medical Screening and Evaluation An evaluation is helpful to establish a baseline. A physician's physical examination may include some of the items that will be discussed. The purpose of this separate evaluation, however, is to establish a baseline of fitness, assist in planning an exercise program, and recommend corrective measures or further testing for problems observed. A number of decisions must be made to determine the most appropriate type of evaluation. The location of the evaluation can be a fitness facility, professional office, hospital, school, work site, or mobile van. The comprehensiveness of the testing and the number of tests administered will determine how many individuals can be tested at one time. For example, if maximal stress testing is done on a treadmill with a 12-lead ECG, more time and personnel will be required than for submaximal testing with telemetry monitoring on a bicycle ergometer. Specific tests must vary and match the group to be tested. For example, strength testing of shoulders may not be necessary for women interested in fat loss but, for a fireman, such a test would be mandatory. A group of 25year-old highway patrolmen would not benefit as much from 12-lead ECG monitoring as a group of 50-year-old executives. Comprehensiveness of the testing may also come down to finances. Compromises may be necessary to reduce costs of administration—specifically personnel and equipment. Because some of the tests can be carried out by relatively inexperienced personnel, a clinician can use those being tested to monitor testing stations. Another consideration is work specificity. Is the test designed to be relevant to job requirements or is it for healthrelated components of fitness? If work-related testing is a factor in hiring or firing, then all tests must be shown to represent abilities required for functioning successfully on the job. Can a highway patrolman of 26% body fat be shown to be less capable of handling his job than one of 15%? Such a test may not be used to hire or fire even though it may be linked to optimal health. Classification of test results poses a problem. Most individuals are motivated by a comparison of their specific results with others of similar age and sex. The comparison standards are difficult, however, because of the high variability of testing procedures, variability of the test itself, or lack of adequate sampling for noncollege age groups and different sports. Establishing what is an optimal result for many tests is also difficult. For example, what is optimal flexibility of the hamstring muscles—90 degrees or 110 degrees? Will a more flexible individual have fewer injuries? Should 90 degrees be classified as fair, good, excellent, or optimal? However testing standards have been developed, care must be given to select standards of the highest reliability. Components that may be tested are cardiovascular endurance, joint screening, body composition, muscle strength, flexibility, pulmonary function, and blood chemistry. These evaluation procedures are in addition to the examination done by a physician. Cardiovascular endurance. The evaluator may choose from a variety of tests including measured oxygen consumption testing with full 12-lead ECG, maximal treadmill testing estimating the oxygen consumption (Vo2), submaximal bicycle testing estimates of Vo2 with or without ECG monitoring, step tests with heart rate recovery, or field tests.16 Decisions must be made on the importance of physiological and metabolic components or ECG results. Physician supervision and interpretation may be mandatory for some tests, and others may be done without the physician present. Body composition. Testing choices are underwater weighing, impedence testing, skin fold measurements, and girth measurements.16 Each test has its advantages and disadvantages. Underwater weighing with measured residual volume (not estimates by vital capacity) still is considered to be the best of these methods. Impedence testing is much faster, but it has not been proved with many types of patients. Skin fold measurements vary according to the tester's capabilities and the specific formula that is used. Girth measurements are helpful to show local changes and may be better used as a motivator for those who have higher percentages of body fat. Joint screening. Many physical fitness evaluations do not include joint screening because, either the clinicians lack expertise or do not recognize its value. Joint screening is certainly an important measure because abnormalities of the musculoskeletal system may require modifying the type of cardiovascular exercise one performs. The joints most important to be screened are the shoulders, low back, knees, feet, and ankles. Screening procedures include postural evaluation of anatomical abnormalities, range of motion and strength, ligamentous stability, and dynamic biomechanical evaluation PHYSICAL THERAPY 1842 Downloaded from http://ptjournal.apta.org/ by guest on September 11, 2014 that may include videotape analysis. Corrective recommendations, such as strengthening, range-of-motion, or proprioceptive exercises; foot orthotics; or improved or modified body mechanics, enhance a patient's abilities to continue exercise indefinitely. Muscle strength. An evaluator has multiple choices for testing this component. Consideration must be given to the muscle groups most important for the group being tested. Testing can be done by using Cybex®* or isokinetic devices, isotonic devices, isometric devices, tests done against an individual's body weight, or manual muscle testing. The best approach may be to rule out pathological conditions first with manual muscle tests and then to test specific muscle groups that correlate with functional activities. Areas of the body to be tested include the upper extremities, lower extremities, abdominal muscles, and back extensor muscles. Explanatory statements should emphasize the specificity of strength measurements. Testing procedures should be similar to the most appropriate method of carrying out remedial exercises. For example, in place of performing a timed, bent knee sit-up with the knees held as a test of abdominal endurance, a more appropriate test might be the absolute number of abdominal curls performed by the patient with the legs over a chair. Care must also be used in selecting one-maximum repetition tests because of their injury potential. Flexibility. Often, the evaluator administers the sit and reach test and draws general conclusions from it as to total body flexibility. Flexibility is specific to the muscle group being tested. Comprehensive lower extremity testing may be appropriate for athletes. Measurements can be made objectively by goniometer or estimated visually. The latter testing can be graded as hypermobile (4), normal (3), tight (2), or very tight (1). Comprehensive testing might include hamstring, gastrocnemius, soleus, quadriceps femoris, hip flexor, hip adductor, low back, tensor fascia lata, hip external rotator, and hip internal rotator muscles.17 Differentiation must be made between capsular and muscle tightness. Pulmonary function. Forced vital capacity and forced expiratory volume in one second (FEVi) are the most important screening procedures. Another important test is FEV25-75. Residual volume testing can be done if precise underwater weighing body composition results are desired. Blood chemistry. A lipid panel with determinations of total cholesterol, high density lipoprotein (HDL), low density lipoprotein, very low density lipoprotein, total cholesterol to HDL ratio, and triglycerides may be very important, especially for men who are over 40 years of age. Many other blood chemistry panels can be done at relatively little expense. Consultation Consultation may include a description of the tests, individual specific results, a categorization of the results by comparison with similar age and sex groups, and a presentation of an individualized exercise plan. The plan is based on the history questionnaire, individual goals, and results of the screening evaluation. Computerization of these results is possible and may enhance acceptability by those tested. The computer also provides group summaries that would be help- * Cybex, Div of Lumex, Inc, 2100 Smithtown Ave, Ronkonkoma, NY 11779. ful to management. A consultation may be given individually or in a group. Further comprehensive testing may be indicated by the screening testing results. Referral may be made to other health professionals. Exercise recommendations should be given for cardiovascular endurance activities, strengthening, and flexibility. The therapist should give specifics for frequency, duration, and intensity for each type of exercise; progression; short- and long-range goals; and appropriate recreational activities and activities of daily living. Exercise Performance If we examine the types of programs that are provided at this time, we see a great variation in application and style. We can, however, basically classify all programs into four categories: 1) home programs or individually carried-out programs; 2) company-sponsored programs that may include partial payment of memberships in YMCAs or YWCAs, racquetball centers, or health spas; 3) company-sponsored programs outside of the work place (eg, softball program at a county recreational facility or aerobic dancing at a nearby gymnasium); and 4) company-sponsored and organized programs at in-house facilities. Each of these programs has specific advantages and can be used depending on company resources and commitment. Company-sponsored programs outside of the work environment relieve the company of some administration and planning. The employer does have some control over the content of the program and may choose a specific program for a target health problem (eg, hypertension, obesity, or diabetes). Company-sponsored in-house programs offer greater potential for long-term adherence because the employees have the greatest opportunity to participate in these programs. An in-house program also gives the employer the opportunity to research cost-effectiveness. Successful company fitness programs have the following characteristics10: 1. Top level management participates. 2. Dynamic professional leadership is employed or contracted. 3. The program emphasizes endurance exercise with adjunctive strengthening and flexibility programs and also includes recreational activities and sports. 4. Participants join with a partner of similar ability at least one time a week for exercise. 5. Performance agreements may be exchanged among the partners. 6. Exercise logs are completed and turned in to the program director monthly. Comments from the director are resubmitted to the participant. 7. Exercise clubs are formed such as bicycling, swimming, and jogging. 8. Safe competition is built in for interested participants after baseline level of fitness has been achieved. 9. A logo, T-shirts, and awards are used. Progress Reassessment Periodic reassessment is done to determine progress and maintain motivation. Complete reevaluations may be done on an annual basis with similar interim evaluations every two to three months. Volume 65 / Number 12, December 1985 Downloaded from http://ptjournal.apta.org/ by guest on September 11, 2014 1843 SUMMARY Preventive programs for business and industry are being established with increasing frequency. Economic motivation, either directly or indirectly, is the major reason for implementation. Personnel with many backgrounds have contributed to these programs. Physical therapists can play a major role because of their musculoskeletal expertise. Those with cardiopulmonary backgrounds in electrocardiography, cardiopulmonary pathology, and exercise physiology are even more valuable to the programs. REFERENCES 1.
