External supports improve knee performance in anterior cruciate ligament reconstructed individuals with higher kinesiophobia levels.

BACKGROUND The objectives of this study were to investigate the effects of knee brace (KB) and kinesiotaping (KT) on functional performance and self-reported function in individuals six months post-ACLR who desired to return to their pre-injury activity levels but felt unable to do so due to kinesiophobia. METHODS This was a cross-sectional study involving 30 individuals six months post-ACLR with Tampa Kinesiophobia Scores >37. Individuals were tested under three conditions: no intervention, KB and KT in a randomized order. Isokinetic concentric quadriceps and hamstring strength tests, one leg hop test, star excursion balance test and global rating scale were assessed under the three conditions. RESULTS The involved side showed that KT and KB significantly increased the hop distance (P=0.01, P=0.04) and improved balance (P=0.01, P=0.04), respectively, but only KB was found to increase the quadriceps and hamstring peak torques compared to no intervention (P<0.05). Individuals reported having better knee function with KB when compared to no intervention (P<0.001) and KT (P=0.03). CONCLUSIONS Both KB and KT have positive effects in individuals post-ACLR which may assist in reducing kinesiophobia when returning to their pre-injury activity levels, with the KB appearing to offer the participants better knee function compared to KT.

Which one Enhances Muscular Performance in ACL Reconstructed Subjects Brace or Tape

Objectives: The aim of this study was to investigate the effects of functional knee brace and kinesiotaping on muscular performance in anterior cruciate ligament reconstructed subjects who reached return to sport phase of the rehabilitation. Methods: Twenty (17 males, 3 females, Age: 24.7±7.1 years, Body weight: 74.4±12.0 kg, Height: 177.9±6.5 cm, BMI: 23.9±3.6 kg/m2) subjects who underwent anterior cruciate ligament reconstruction by using hamstring tendon auto graft were included in this study. When the subjects reached the return to sports phase of rehabilitation which was 6th months after surgery, knee muscle strength, jump performance and balance tests were performed 3 times: bare, with knee brace and with kinesio taping. The order of the tests were randomized to eliminate the effects of fatigue and motor learning. Quadriceps and hamstring muscle strength was measured on an isokinetic dynamometer at 180 °/s and 60°/s angular velocities. Vertical Jump (VJ) and One Leg Hop Tests (OLHT) were used to assess jump performance. Star Excursion Balance Test (SEBT) with anterior, posteromedial and posterolateral reach distance was used to assess the dynamic balance. When all tests were performed, the subjects were asked under which test condition they felt more confident. Repeated measures of ANOVA was used to analyze the difference among three test conditions (bare, kinesiotaping, knee brace). Bonferroni post hoc test was used for pairwise comparison. Results: SEBT posteromedial (PM)and posterolateral (PL) reach distances were found significantly different among three test conditions(PM: F(2,38)=3.42,p=0.04), PL: F(2,38)=4.37,p=0.02). Kinesiotaping increased posteromedial reach distance (p=0.03). On the other hand, brace decreased posterolateral reach distance (p=0.04). VJ and OLHT performance were also found significantly different between three test conditions (VJ: F (2,38)=3.44,p=0.04, OLHT: (F(2,38)=4.04,p=0.02). Kinesio taping increased one leg hop distance (p=0.01). However, brace decreased VJ distance (p=0.04). Kinesiotaping had no effect on quadriceps and hamstring strength (p>0.05). Only brace increased the quadriceps strength at 180 °/s (p=0.02). 40% of the subjects felt more confident with knee brace; 25% of them were more confident with kinesiotaping and the rest (35%) of them were more confident with no brace and kinesiotaping. Conclusion: Kinesiotaping enhances balance and jump performance except for increasing knee strength in ACLR subjects at 6th months after surgery when they normally return to their sport. Although, knee brace increases quadriceps strength, it has adverse effect on functional performance . Therefore, Kinesiotaping can be applied for those patients when they start their sport specific training to enhance functional performance.

Effect of Kınesıotapıng and Knee Brace on Functıonal Performance in Recreatıonal Athletes

Objectives: Kinesiotaping is a popular taping method that is used for both therapeutic and performance enchancement purposes. Knee braces are widely used for prevention in sport injuries but their performance effectiveness is still controversial. The aim of this study was to determine whether kinesiotape or brace was more effective on functional performance. Methods: A total twenty male recreational football players (Mean±Standart Deviation (SD) age: 22.5±0.68 years, height: 175.15±3.37 cm, body weight: 74.52±12.41 kg), voluntarily participated in this study. Participants were tested with kinesiotape, with brace and without kinesiotape and brace. Tests were applied one day after patellar kinesiotaping (correction technique). Balance property measured with Modified Y balance Test (dynamic test), agility measured by T test, muscle strength and anaerobic power assessed by vertical jump and triple hop tests. Wilcoxon signed rank test was employed for determining the statistical significance of tests with kinesiotape, with brace and without kinesiotape and brace. Results: In analysis; There were statistically significant differences found in Triple hop test with kinesiotaping and without kinesiotaping and brace, in T test with bracing and kinesiotaping, in vertical jump with kinesiotaping and without kinesiotaping and brace (p<0.001) (in the favour of kinesiotaping in all tests) No statistically significant difference was found in modified Y balance test all groups (p> 0.05). Conclusion: Consequently, kinesiotaping had positive effects on agility and muscle strength but had no effects on balance in football players. On the other hand, brace had no effects on functional performance tests.
