Güzel İ. Early Effects of Different Sensory Stimuli on Balance, Joint Position Sense and Light Touch Sensation Applied to the Knee Joint in Healthy Individuals, Hacettepe University Institute of Health Sciences, Orthopedic Physiotherapy and Rehabilitation Master Thesis, Ankara, 2020. The aim of this study was to investigate the early effects of stimuli for different sensory receptors on joint position sense, balance and mild tactile sensation in healthy individuals and to compare these effects with each other. A total of 125 healthy subjects aged between 18-40 years were included in the study. The participants were divided into 5 different groups according to application types: 1) hot application group, 2) cold application group, 3) pressure application group, 4) vibration application group and 5) pain application group. Stimuli were applied as 20 minutes hotpack to the knees of the participants in the Hot Application Group, 15 minutes coldpack to the knees of the participants in the Cold Application Group, 5 minutes pressure with blood pressure cuff to the knees of the participants in the Pressure Application Group, 5 minutes vibration with diaposon to the knees of the participants in the Vibration Application Group; 60 seconds pain with Burst TENS to the knees of the participants in the Pain Application Group. Participants in each group were evaluated before and after these 5 applications. The measurement results before and after the application were analyzed by comparing them within and between groups. After the application, it was observed that the balance in the Cold Application Group was deteriorated, and the sense of joint position and light touch decreased (p<0.05). In the Hot Application Group and Pressure Application Group, it was found that the balance improved after application and the sensation of joint position and light touch increased (p<0.05). There was no significant difference between the Vibration and Pain Groups before and after the application (p>0.05). When the application groups were compared with each other, a significant difference was found between the groups for each parameter. In line with these findings, it was found that hot application and pressure application increased the knee joint position sense, light touch and balance; however, it was concluded that cold application negatively affected these parameters.
