Objective & Hypothesis

Results

Objective• To determine if Kinesio® Tape has an effect on eccentric force

production of the rectus femoris in healthy, non-injured individuals as measured by the Biodex System 4 Pro Isokinetic Dynamometer.

Hypothesis• Kinesio® Tape applied for muscle facilitation of the

quadriceps femoris will improve overall eccentric muscle torque as measured by the Biodex System 4 Pro Isokinetic Dynamometer.

• Kinesio® Tape is a therapeutic elastic tape created to simulate the elasticity of human skin, and is used for a multitude of applications ranging from rehabilitation to optimization of performance.

• Multiple studies have investigated Kinesio® Tape’s effects on concentric strength. However, current literature islimited regarding Kinesio® Tape’s effects on eccentric contractions.

Randomized Controlled Trial conducted at Florida Gulf Coast University

Partiicpants

• 51 healthy individuals ages 18-40 years. • No knee injury or surgery in the past 6 months, no lower

extremity rehabilitation in the last 6 months, no use of Kinesio® Tape around the knee within the past month, medically cleared PAR-Q and Health History Questionnaire.

Interventions

• Kinesio® Tex Tape Gold with a “Y” cut for muscle facilitation technique for the rectus femoris.

Outcome Measures

• Muscle peak torque (ft-lbs), time to peak torque (milliseconds), average peak torque (ft-lbs) measured at 60 deg/sec and 180 deg/sec for the rectus femoris on the Biodex Isokinetic Dynamometer.

• IBM SPSS Statistics v22 • Paired t-Test for dependent samples • Variables:

peak torque, time to peak torque, angle of peak torque, max repetition total work, total work, average power, acceleration time, deceleration time.

Tape vs. No Tape:• there were no statistical differences found regardless

of the speed of the eccentric contraction.

First Trial vs. Second Trial:• regardless of the tape condition resulted in a

statistically significant greater average power for the second trial.

Data Analysis

• This study’s findings were inconclusive as to the ability of Kinesio® Tape to affect the eccentric force production of the quadriceps.

• Further research should include sham tape and mitigating the learning effect of the Biodex Isokinetic Dynamometer in eccentric mode.

Table 2. First Trial vs. Second Trial Data

• The data from this RCT provided inconclusive results as to the ability of Kinesio® Tape to affect the eccentric force production of the quadriceps femoris.

• The data comparing first and second trials showed a significant learning effect was present for the use of the Biodex in a randomized controlled trial.

• The Biodex also proved difficult for some participants to learn as eccentric contractions can be more difficult to understand.

• One limitation of this study is the sole use of healthy, non-injured participants.
