OBJECTIVE: To evaluate the efficacy and safety of short-wave therapy with sham or
no intervention for the management of patients with knee osteoarthritis. METHODS :
We searched the following databases from their inception up to 26 October 2016 :
MEDLINE, CENTRAL, EMBASE, Physiotherapy Evidence Database, CINAHL and OpenGrey. Studies included randomized controlled trials compared with a sham or no
intervention in patients with knee osteoarthritis.
The results were calculated
via standardized mean difference (SMD) and risk ratio for continuous variables
outcomes as well as dichotomous variables, respectively. Heterogeneity was
explored by the I2 test and inverse-variance random effects analysis was applied
to all studies. RESULTS: Eight trials (542 patients) met the inclusion criteria.
The effect of short-wave therapy on pain was found positive
(SMD, -0.53; 95% CI,
-0.84 to -0.21). The pain subgroup showed that patients received pulse modality
achieved clinical improvement (SMD, -0.83; 95% CI, -1.14 to -0.52) and the pain
scale in female patients decreased (SMD, -0.53; 95% CI, -0.98 to -0.08). In terms
of extensor strength, short-wave therapy was superior to the control group ( p <
0.05, I2 = 0%). There was no significant difference in the physical function
(SMD, -0.16; 95% CI, -0.36 to 0.05). For adverse effects,
there was no
significant difference between the treatment and control group. CONCLUSION:
Short-wave therapy is beneficial for relieving pain caused by knee osteoarthritis
(the pulse modality seems superior to the continuous modality), and knee extensor
muscle combining with isokinetic strength. Function is not improved.
