This randomized sham-controlled trial investigates the acute effects of upper arm tissue flossing on upper extremity performance and power in healthy adults. Tissue flossing is a compression-based intervention that involves wrapping an elastic band around a limb for a short period while performing movement exercises.
Twenty-eight healthy participants are randomly assigned to either an active tissue flossing group or a sham flossing group. The intervention is applied to the dominant upper arm. Upper extremity performance is assessed before the intervention and at 2 and 15 minutes after the intervention using the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) and the Seated Medicine Ball Throw (SMBT).
The study aims to determine whether a single session of upper arm tissue flossing can produce immediate improvements in upper extremity stability, functional performance, and explosive power compared with a sham intervention
Tissue flossing is a relatively new technique used in sports and rehabilitation settings. It involves applying a specialized elastic compression band around a limb while the individual performs active movements. Proposed mechanisms include temporary vascular occlusion followed by reperfusion, alterations in neuromuscular function, and changes in fascial tissue mobility. Although tissue flossing has been investigated for lower extremity performance and range of motion outcomes, evidence regarding its effects on upper extremity performance remains limited.
The purpose of this study is to examine the acute effects of upper arm tissue flossing on upper extremity functional performance and power in healthy adults. This study is designed as a randomized, sham-controlled, parallel-group trial.
A total of 28 healthy volunteers are randomly allocated to either an active tissue flossing group or a sham flossing group. Participants in the active intervention group receive tissue flossing applied to the dominant upper arm using a standardized compression protocol. Participants in the sham group receive a loosely applied band that does not provide therapeutic compression. During band application, participants perform standardized upper extremity movements.
Outcome measurements are obtained at baseline, 2 minutes after intervention, and 15 minutes after intervention. Upper extremity functional performance is assessed using the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST). Explosive upper-body power is assessed using the Seated Medicine Ball Throw (SMBT).
The primary objective is to determine whether upper arm tissue flossing produces immediate improvements in upper extremity stability and performance compared with a sham intervention. Findings from this study may contribute to understanding the potential role of tissue flossing as a practical strategy for enhancing upper extremity performance in healthy individuals and physically active populations.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Active Flossing Group | Experimental | Participants (n=14) receive a structured circumferential compression protocol on their dominant upper arm using an elastic latex floss band stretched to moderate tension, followed by a brief active movement sequence. |
|
| Sham Flossing | Sham Comparator | Participants (n=14) receive a loose, minimal-tension wrap on their dominant upper arm using the same floss band type, performing the identical active movement sequence to isolate the effects of compression intensity |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Active Myofascial Compression | Other | The floss band is applied to the participant's dominant upper arm by a licensed physiotherapist. Wrapping proceeds in a distal-to-proximal direction with approximately 50% overlap between layers, terminating just distal to the axilla. The band is stretched to a standardized elongation between 50% and 70% of its maximal length to generate moderate circumferential compression. Once wrapped, the participant performs a standardized 2-minute low-to-moderate intensity active movement sequence consisting of repeated elbow flexion/extension, shoulder flexion/extension, and forearm pronation/supination. The band is fully removed immediately following the 2-minute movement block |
| Measure | Description | Time Frame |
|---|---|---|
| Seated Medicine Ball Throw (SMBT) distance | Upper-extremity explosive power was assessed using the seated medicine ball throw. Participants were seated upright with back support and projected a 2-kg medicine ball horizontally as far as possible in a chest-pass motion. Throw distance was measured from a fixed start line to the point of initial ball contact. | Measured at three time points: Baseline (Pre-intervention), 2 minutes post-removal, and 15 minutes post-removal |
| Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) score | Upper-extremity closed-chain stability was assessed using the CKCUEST. Participants assumed a full push-up (high-plank) position with hands placed on two parallel strips of tape positioned 91.4 cm apart. Participants alternately touched the opposite hand as rapidly as possible for 15 seconds. The metric recorded is the total number of completed hand touches within the 15-second interval. | Measured at three time points: Baseline (Pre-intervention), 2 minutes post-removal, and 15 minutes post-removal. |

This study employed a randomized, sham-controlled, parallel-group, repeated-measures design to examine the acute effects of upper-arm tissue flossing on closed-chain upper-extremity stability and seated upper-body power. Outcome assessments were conducted at three distinct time points: immediately before the intervention (Pre), 2 minutes after band removal (Post2), and 15 minutes after band removal (Post15).

Outcome measurements at all time points were performed by a single trained assessor who was blinded to group allocation and had no involvement in intervention delivery. To support participant blinding, all individuals were informed that they would receive one of two compression-based protocols but were not informed which condition was expected to be more effective
|
| Sham Myofascial Wrap | Other | The floss band is applied to the participant's dominant upper arm by the same physiotherapist, maintaining identical therapist contact time, limb positioning, and overall session duration as the active group. However, the band is applied with less than 10% elongation, creating a loosely snug contact fit insufficient to generate meaningful circumferential compression or local vascular occlusion. Once wrapped, the participant performs the exact same 2-minute low-to-moderate intensity active movement sequence (elbow flexion/extension, shoulder flexion/extension, and forearm pronation/supination) before the band is fully removed. |
