Original Eccentric Exercise/Tendinitis Study

Eccentric exercise in chronic tendinitis.Stanish WD, Rubinovich RM, Curwin S. Clin Orthop Relat Res. 1986 Jul;(208):65-8.

Chronic tendinitis, particularly of the Achilles tendon, frequently outwits traditional programs of therapy including surgery and/or prolonged immobilization. A hypothesis proposes that disruption of the tendon, micro or macro, occurs under specific conditions of eccentric loading. In order for the healing tendon to be adequately rehabilitated, the treatment program must include specific eccentric strength rebuilding exercises.

Diagnosis:  Nonspecific tendinitis

Outcome:  “44% of patients had complete relief of pain and function impairment, 43% had a marked decrease in symptoms (complaining of mild pain after athletic activities), 9% had virtually no change in their clinical state, and 2% were worse after the exercise program.”

When Assessed:  16 months

Subjects:  200 patients with tendinitis lasting 18 months, failed prior physical therapy and had at least 3 corticosteroid injections

Protocol:  6 week program, 3 sets of 10 reps, 1x per day, slow speed, medium speed, then fast speed, then add resistance.

Other Activity:  No mention.

Chad’s Comments:  Oldest of the research. No control, not very well described. 6 week program, but mean follow up was not until 16 months after the initiation of treatment.
