Early Symptom Intervention

What is an Early Symptom Intervention?

Early symptom intervention, ESI, is a program designed to help improve employee health by focusing on alleviating musculoskeletal discomforts. By improving the employee’s health, the company should see an increase in productivity, a reduction in injury rates and a decrease in worker’s compensation cost. Companies that utilize ESI programs have reported a 100% return on investment and 90% reported a reduction of loss time by 25%.¹  The ESI program focuses on improving musculoskeletal discomforts by developing exercise programs, utilizing soft splints, posture modifications and ice or heat. ESI could address conditions including but not limited to sprains and strains, muscle tightness, soreness and fatigue.
