Effects of kinesio taping on venous symptoms, bioelectrical activity of the gastrocnemius muscle, range of ankle motion, and quality of life in postmenopausal women with chronic venous insufficiency: a randomized controlled trial.

OBJECTIVE

To assess the efficacy of Kinesio taping (KT) on venous symptoms, quality of life, severity, pain, edema, range of ankle motion (ROAM), and peripheral muscle myoelectrical activity in lower limbs of postmenopausal women with mild chronic venous insufficiency (CVI).

DESIGN

Double-blinded randomized controlled trial with concealed allocation.

SETTING

Clinical setting.

PARTICIPANTS

Consecutive postmenopausal women (N=123; age range, 62-67y) with early-stage CVI. None of the participants withdrew because of adverse effects.

INTERVENTION

Participants were randomly assigned to an experimental group for standardized KT application for external gastrocnemius (EG) and internal gastrocnemius (IG) muscle enhancement and ankle function correction or a placebo control group for sham KT application. Both interventions were performed 3 times a week during a 4-week period.

MAIN OUTCOME MEASURES

Venous symptoms, CVI severity, pain, leg volume, gastrocnemius electromyographic data, ROAM, and quality of life were recorded at baseline and after treatment.

RESULTS

The experimental group evidenced significant improvements in pain distribution, venous claudication, swelling, heaviness, muscle cramps, pruritus, and CVI severity score (P≤.042). Both groups reported significant reductions in pain (experimental group: 95% confidence interval [CI], 1.6 to 2.1; control group: 95% CI, -0.2 to 0.3). There were no significant changes in either group in quality of life, leg volume, or ROAM. The experimental group showed significant improvements in root mean square signals (right leg: EG 95% CI, 2.99-5.84; IG 95% CI, 1.02-3.42; left leg: EG 95% CI, 3.00-6.25; IG 95% CI, 3.29-5.3) and peak maximum contraction (right leg: EG 95% CI, 4.8-22.7; IG 95% CI, 2.67-24.62; left leg: EG 95% CI, 2.37-20.44; IG 95% CI, 2.55-25.53), which were not changed in controls.

CONCLUSIONS

KT may reduce venous symptoms, pain, and their severity and enhance gastrocnemius muscle activity, but its effects on quality of life, edema, and ROAM remain uncertain. KT may have a placebo effect on venous pain.
