Comparison of the effects of vibration technique and resistive exercise on knee pain and proprioception in patients with chondromalacia patellae

Abstract

Methods: In the present study, 35 men (mean ± standard deviation of: age = 22.6±2.9 years, height = 175.5±8.3 cm, and weight =77.6±9.3 kg) were selected via convenience sampling and randomly assigned to three groups, including the vibration technique (n=12), resistive exercise (n=12), and control (n=11). The first two groups followed their own specific protocol 3 days per week for 8 weeks, and were forbidden from participating in any sport or physical activity. Pain intensity and active angle reproduction error (AARE) for 45˚ knee flexion were assessed using Visual Analogue Scale (VAS) and the Biodex system.
