OBJECTIVE: To investigate the effectiveness of aquatic exercise in improving
lower limb strength in people with musculoskeletal conditions.
DATA SOURCES: A
systematic search used 5 databases, including MEDLINE, CINAHL, Embase,
SPORTDiscus, and The Cochrane Library.
STUDY SELECTION: Randomized controlled
trials evaluating aquatic exercise with a resistance training component for
adults with musculoskeletal conditions compared with no intervention or
land-based exercise were identified. Fifteen studies from the initial yield of
1214 met these criteria. DATA EXTRACTION: Data related to participant
demographics, study design, and methods, interventions, and outcomes, including
numerical means and SDs, were extracted independently by 2 reviewers. DATA
SYNTHESIS: Nine of the 15 studies were of high quality, scoring at least 6 on the
Physiotherapy Evidence Database Scale. Limited consideration of the prescription
of resistance in the aquatic exercise and application of resistance training
principles existed. Low- or very low-quality evidence indicates there was no
difference in average effect between aquatic exercise and no exercise in
improving hip abductor strength (standardized mean difference [SMD], .28; 95%
confidence interval [CI], -.04 to .59), knee extensor strength (SMD, .18; 95% CI,
-.03 to .40), knee flexor strength (SMD, .13; 95% CI, -.20 to .45), or lower limb
endurance (SMD, .35; 95% CI, -.06 to .77). Low-quality evidence indicates no
difference in average effect between aquatic and land exercise for knee extensor
(SMD, -.24; 95% CI, -.49 to .02) or flexor strength (SMD, -.15; 95% CI, -.53 to
.22). CONCLUSIONS: It is likely that the inadequate application of resistance in
water is a significant contributor to the limited effectiveness of aquatic
exercise interventions in improving hip and knee muscle strength in people with
musculoskeletal conditions. Future research is needed to quantify resistance with
aquatic exercises and to determine if using opportunities for greater resistance
in aquatic rehabilitation and appropriate resistance training principles can be
more effective in improving muscle strength.
