Three-Part Question:
In [adults with lateral epicondylitis] is [eccentric exercise more beneficial than other non invasive treatments] at [decreasing pain and improving function]
Clinical Scenario:
A 31 year old male presents with a 3 month history lateral epicondylitis. You are planning to use standard treatments of electrotherapy, ICE, and exercises to improve his symptoms. You have heard from a colleague about an exercise regime based on eccentric muscle contractions and you wonder if there is any evidence of greater efficacy than the usual treatments.

Cochrane Database and PEDro database: lateral epicondylitis
Outcome:
7 papers and 1 abstract were retrieved. Only 3 papers and the abstract were relevant to the 3 part question. There is a Cochrane protocol registered but not converted to a review (Smidt 2004).

All received
Eccentric exercise
Single group study comparing to uninjured side. 1. Pain VAS 1. mean decrease of 5/10 Generally insufficient data to perform detailed analysis
2. Strength 2. torque diff between injured/uninjured side = NSS
3. Return to activity 3. 13/15 subjects moderate/marked/ complete decrease in symptoms
4. Ultrasound scan 4. no data available
Adapted eccentric training in chronic lateral epicondylitis rehabilitation Croisier, Jl., Foidart,M. Crielaard,JM., Forthomme,B 2005 France N = 76 lateral epicondylitis
2 groups of treatment
Eccentric exercise v conventional physio treatment (TENS, ICE, ultrasound therapy, frictions, stretching)
Abstract 1. VAS 1. After 20 treatments Eccentric group less pain than control (P < 0.01) Abstract only.
Patients assigned, not randomised.
Control group had other multiple treatments
No detailed results data available
2. Return to offending activity 2. Return with complete or marked relief of symptoms 74% of treatment group v 33% control group
3. Strength 3. No data available
4. Ultrasound scan 4. Improved tendon structure 89% treatment group v 60% control group.

Clinical trial.
Parallel group design
1.VAS 1. Gp 1= 8.8 – 1.9@wk4 +1.5@wk16; Gp. 2 = 8.6 - 1.7 @ Wk4 + 1.6@wk16. NSS between Gps. But within Gps p < 0.0005 Sequential allocation not randomisation
No power calculation
Author Commentary:
There is one study in abstract form directly comparing eccentric exercise with standard physiotherapy for tennis elbow. This reveals some limited evidence of the benefit of eccentric exercise, but detailed critique cannot be made on the abstract. There is some other limited data from full papers that eccentric training is no better than either ICE and/or stretching treatments.
Bottom Line:
Present limited evidence suggests that eccentric exercise is no better than other standard physiotherapy treatments for chronic lateral epicondylitis.
