The immediate effects of kinesiotm taping on shoulder external rotation in people with shoulder pain

Abstract

Objectives: Observing the immediate effect of KinesioTMTaping(KT) on dynamic balance(DB) and acceleration(ACC) of athletes and sedentary subjects Methods: The mean ages of athletes(n=25) and sedentary(n=25) were 21,36±2,07 and 21,64±1,62 years, weight 82,36±1,75 and 79,48±7,41kg, height 1,81±0,65 and 1,77±0,56cm, and body mass index were 24,99±4,07 and 25,20±2,12kg/cm2, respectively. They were all male and students of Yeditepe University. The athletes were in the soccer and American football teams of the university. All gave their own written consent to participate in the test protocols of the study voluntarily. Their lower extremity (LE) muscle power (JTech Myometry), and the flexibility of the LE antigravity muscles were assessed before. Their DB (Prokin PK 200) of both sides, speed and acceleration in 30m sprint (Research Tracker RT6) were assessed as before and after the KT applications on both calves to observe their immediate effects on the gastrosoleus group of muscles (p<0.05). The Y shaped KT were used starting from Achilles tendon as one piece and ending over medial and lateral heads of M.Gastrocnemius. Descriptive statistics were used to understand the physical properties of the participants. Wilcoxon and Mann- Whitney-U tests were used for the significance (p< 0.05) of the data and Pearson Correlation was used to understand the relation between the data. Results: Athletes’ lower extremity muscles were stronger (p< 0.05) than the sedentary, except the M.Gluteus maximus and ankle invertors. They achieved higher performance in 30m sprint and in DB tests than the sedentary. KT on gastrosoleus group improved the DB of both sides as perimeter length(°) of the centre of pressure (COP) and the area covered (%) by COP (p< 0.05) of the athletes, but not in the ML and AP displacements (°) of COP. The athletes forward (X) and resultant (XYZ) ACC and velocity (m/sec) were significantly higher after KT application (p<0.01). The soleus, ankle invertors-evertors were effective on the forward (X) ACC, but invertors were also effective on mean velocity of the athletes, compared to sedentary. Conclusion: The athletes benefited from the immediate effects of KT application during sprinting. It increased the ability of athletes to control the movements of COP in shorter distance and smaller area compared to sedentary. Since there is no difference in AP-ML displacement of COP of both groups, we can conclude that KT does not have immediate effect on ankle strategy for DB.
