About Us


Our patented post offer employment testing system provides the definitive answers to these often unanswerable questions.
  • Does your new hire have the strength and fitness required to do their job?
  • Does your new employee have a pre-existing injury?
  • Is your employee ready to return to their job after recovering from an injury?
It is designed to assist employers in preventing workplace injuries by properly matching their employees’ physical abilities to their new job. Utilizing state-of-the-art, proprietary software, the PCP machine completes a collection of multiple strength measurements in as little as 30 minutes with results available to employers within minutes. 

Company Profile

From its start in 1988 as a single testing clinic in Salina, Kan., Occupational Performance Corporation (OPC) has expanded into a network of 100+ independently owned testing facilities located across the country. Orthopedic Surgeon, Dr. Gary Harbin, developed and patented the Physical Capacity Profile® (PCP) Testing System in response to numerous industry requests for help in reducing work-related injuries and associated workers’ compensation expenses. Dr. Harbin, like many medical professionals, found himself trying to determine how strong his patients had been, prior to an injury, by measuring an uninjured limb or by making educated guesstimates based on his education and experiences. The PCP provides him with better objective medical information, therefore reducing the medical liability that comes from the subjective nature of “guesswork”.

The PCP Testing System is used by medical teams for post-offer or pre-employment physical exams, as well as fit for duty and functional capacity evaluations (FCE’s). This process is very similar to pre-employment physicals provided today. Through computerized software, a comprehensive collection of 28 maximum-strength measurements are collected in as little as 30 minutes. Results are available in minutes for both the medical team and employer. The medical information is obtained and measured utilizing standards from the Department of Labor’s (DOL) five classifications of work and the American Medical Association (AMA) guidelines. The PCP testing system is ADA and HIPAA compliant and has successfully undergone EEOC audits.

Unlike other pre-employment physical exams, such as job simulation or physician physicals, the PCP provides objective baseline data about an employee’s maximum performance. Tests or physicals that do not record objective measurements are of little or no value in the rehabilitation process or in assisting with the reduction of workers compensation claims. Most state statutes only require employers to be responsible for the injury or degree of aggravation they caused. Without reproducible and measurable medical end points, physicians, therapists, and attorneys are simply left with subjective and disputable information.

PCP network locations have collectively tested over 750,000 employees. Current end users include public and private corporations, municipalities, self-insured workers compensation funds, statewide trade associations, and school districts. The labor force tested a wide range of employees: from clerical personnel to heavy industrial laborers. With the PCP system, employers of any kind can be assured they are hiring people with the appropriate strength to perform their jobs. Employees can have confidence that if injured, they will be fairly rehabilitated and/or compensated. When the workplace is safer and fewer claims are filed, EVERYONE wins.
