Lateral epicondylosis (LE) is
relatively common with an annual incidence in the general population of 1% to 3%.
Systematic reviews have identified exercise is effective,
but have not
established specific exercise parameters. PURPOSE: The purpose of this systematic
review was to synthesize the quality and content of clinical research addressing
type and dosage of resistance exercises in lateral epicondylosis. METHODS:
Computerized bibliographic databases (1990-2010) were searched using relevant
keywords; bibliographies of included papers were hand searched. Of 594 screened
abstracts, 11 articles (12 studies) met inclusion criteria. Articles were
randomly allocated to pairs of reviewers who independently verified data
extraction and appraised the full text, using a structured critical appraisal
tool with 24 items. Data extraction was limited by a lack of consistent reporting
of elements of exercise dosage. RESULTS: The mean quality rating of the studies
was 72%, with 2 papers exceeding 75% quality. Of the 12 studies, 9 addressed the
effects of isotonic (eccentric/concentric) exercises, 2 studied the effect of
isometric and one studied isokinetic exercises. The exercise programs ranged over
a period of 4 to 52 weeks. Exercises were prescribed 1 to 6 times per day, with
an average duration of 15 minutes per session, and average of 15 repetitions
(range: 3 to 50), with 1 to 4 sets per session. CONCLUSION: All the studies
reported that resistance exercise resulted in substantial improvement in pain and
grip strength; eccentric exercise was most studied. Strengthening using
resistance exercises is effective in reducing pain and improving function for
lateral epicondylosis but optimal dosing is not defined.
