Objective 
To assess the efficacy of Kinesio Taping (KT) on venous symptoms, quality of life, severity, pain, oedema, range of ankle motion (ROAM) and peripheral muscle myoelectric activity in lower limbs of postmenopausal females with mild chronic venous insufficiency (CVI).

 

Design

Double-blinded randomized clinical trial with concealed allocation.

 

Setting 
Clinical setting.

 

Participants

123 consecutive postmenopausal females (age range 62-67) with early-stage CVI. No participant withdrew because of adverse effects.

 

Intervention

Participants were randomly assigned to an experimental group for standardised KT application for external (EG) and internal (IG) gastrocnemius muscle enhancement and ankle function correction or to placebo control group for sham KT application. Both interventions were performed three 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

Experimental group evidenced significant improvements in pain distribution, venous claudication, swelling, heaviness, muscle cramps, pruritus and CVI severity score (p≤0.042). Both groups reported significant reductions in pain (experimental, 95%CI, 1.6-2.1; control, 95%CI, -0.2-0.3). 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 1.02-3.42; left: EG 3.00-6.25, IG 3.29-5.3) and peak maximum contraction (right leg: EG 95% CI, 4.8-22.7, IG, 2.67-24.62; left: EG, 2.37-20.44, IG, 2.55-25.53), which were not changed in controls.

 

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