Working in just about any profession can put one at risk of repetitive stress injuries of the upper extremities. By contrast, RSI of the lower extremities usually occur in people whose jobs keep them on their feet for a significant portion of the day.
However, this does not necessarily involve intensive manual labor. Teachers, nurses and people who work in retail may be at risk for lower-extremity repetitive stress injury because of the time they spend standing, walking and sometimes climbing stairs. Many types of work-related lower extremity RSI can occur; these are some of the most common ones.
Plantar fasciitis
Shaped like a bowstring, the plantar fascia is a tough band of tissue that supports the arch of the foot. As one walks, the plantar fascia works as a shock absorber. However, according to the Mayo Clinic, jobs that require long hours standing or walking on hard surfaces can put pressure on the plantar fascia, causing it to stretch and tear. Plantar fasciitis pain tends to get better with activity and worse with rest. Patients often report a stabbing pain near the heel on the bottom of the foot.
Trochanteric bursitis
The greater trochanter is a part of the femur, i.e., the long bone of the upper leg. It extends outward from where the head of the femur articulates with the hip. The trochanteric bursa is a sac of fluid that covers the greater trochanter, cushioning and protecting it. Irritation of the bursa results in a painful condition of trochanteric bursitis. The Cleveland Clinic explains that the bursa can become irritated and inflamed due to overuse. Examples may include standing for a long period of time or frequently climbing stairs.
