The Immediate Effects of Tissue Flossing on Knee Flexion Range of Motion

The Immediate Effects of Tissue Flossing on Knee Flexion Range of Motion: A Randomized Controlled Trial

The purpose of this study is to verify the immediate effects of Tissue Flossing on knee flexion range of motion

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Device: Tissue flossing

Detailed Description

After completing the questionnaire, 58 healthy participants will be randomly divided into two groups named Intervention Group (IG) (n=29) and Control Group (CG) (n=29).

In the first assessment (M0), knee flexion ranges will be measured using a goniometer. Then the control group (n=29), without Tissue Flossing and intervention group (n=29) with Tissue Flossing around the knee joint will be subjected to passive and then active mobilization of the knee joint. Immediately after the intervention/control, the two groups will be assessed again (M1).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Intervention group; The floss band will be applied to the knee of the dominant lower limb in the intervention group (IG). While the participant will stand and perform a slight knee flexion, the band will be rolled upwards from the tibial tuberosity to 5 cm above the femoral epicondyle. The patella will not be covered. Pressure will be produced by rolling the joint with 50% tension and 50% overlap. After applying the floss band, passive mobilization will be performed - 20 repetitions of knee flexion and extension and an active movement task - 20 squats. Participants will be instructed to perform knee flexion and extension to their extreme range of motion and to complete the mobility exercises within two minutes. After two minutes, the floss band will be removed and participants will be instructed to stand up and walk for a minute to allow blood to flow back to the foot.	Device: Tissue flossing; While the participant will stand and perform a slight knee flexion, the band will be rolled upwards from the tibial tuberosity to 5 cm above the femoral epicondyle. The patella will not be covered. Pressure will be produced by rolling the joint with 50% tension and 50% overlap.
No Intervention: Control group; For the CG, after initial assessment, participants without a floss band will perform the same two functional movement tasks (active and passive) with 20 repetitions as the GI for 2 minutes. After two minutes, participants will be instructed to get up and walk for one minute like the intervention group.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change of knee range of motion	Data will be collected in two moments: baseline (M0) and after the intervention/control (M1). The knee flexion range of motion will be measured using a smartphone app "Goniometer Pro". The distance between the lateral femoral epicondyle and the center of the lateral malleolus will be assessed. To measure the knee flexion angle, the participant will be placed in the prone position with the hip and knee extended at 0° (goniometer initial position 0°) with the foot relaxed and the contralateral leg extended. For active range of motion, the participant will be asked to perform maximum knee flexion in the prone position. To measure passive movement, the examiner will perform maximum knee flexion on participants in the same position. The average of three repetitions of ranges of movement will be recorded with 30-second rest intervals.	[Time Frame: Change from Baseline (M0) to Immediately after intervention or control (M1)]
