Clinical Trial Summary

Diacutaneous fibrolysis is a physiotherapeutic instrumental technique, used to treat musculoskeletal conditions causing pain and/or movement restriction. It is applied by means of metallic hooks, ending in a spatula with beveled edges, that seems to allow a better pressure distribution on the skin and a deeper and more precise application, compared to the manual approach. Recent studies indicate positive responses regrading pain intensity decrease in sports people suffering anterior knee pain, improving range of motion in subacromial impingement syndrome, improving sensory conductivity in symptomatic patients with carpal tunnel syndrome, decreased pain in patients with chronic epicondialgia or improveing function athletes with anterior knee pain. However, the specific action mechanism, have not been investigated in depth yet. There are no studies evaluating its effects on posterior muscular chain of lower extremity in athletes, where FD effects on neuromuscular response could be more evident due to the overload involved on this area. The aim of this study is to evaluate the immediate, and after 30 minutes, effects of a single diacutaneous fibrolysis session on flexibility, strength and neuromuscular activity on hamstring in athletes. A randomized controlled trial with blind evaluator. Randomization will be done between lower extremities of each subject (Random.org). Regardless of its own dominance, diacutaneous fibrolysis will be applied to de following muscles and intermuscular septums: gluteus maixmus, biceps femoris and semitendinosus to de lower experimental limb. The other extremity will not be treat (control limb). Sample recruitment. Athletes from UIC university community, who compete officially or institutionally, whether they are federated or recorded in a sport official register where the predominant activity focuses on the lower train (athletics, cycling, football, rugby...). Procedure. The anthropometric data will be collected at the beginning of the study. Each outcome assessment will be performed by a blinded evaluator at the baseline, immediately after the technique application and 30 minutes after.

Diacutaneous fibrolysis
Diacutaneous fibrolysis is a physiotherapeutic instrumental technique, used to treat musculoskeletal conditions causing pain and/or movement restriction. It is applied by means of metallic hooks, ending in a spatula with beveled edges. Regardless of its own dominance, diacutaneous fibrolysis will be applied to de following muscles and intermuscular septums: gluteus maximus, biceps femoris and semitendinosus to de lower experimental limb. A single session of 10 minutes will be applied.

Outcome

Type Measure Description Time frame Safety issue
Primary Hamstring neuromuscular activity Hamstring neuromuscular activity (% of muscular fiber recruitment) will be assessed by surface electromyogram (mDurance). The electrodes will be placed on hamstring muscle while performing a functional movement. Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
Primary Gluteus maximus neuromuscular activity Gluteus maximus neuromuscular activity (% of muscular fiber recruitment) will be assessed by surface electromyogram (mDurance). The electrodes will be placed on gluteus maximus muscle while performing a functional movement. Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
Primary Hamstring isometric strength Isometric muscle strength (Kg) will be evaluated by means of a digital dynamometer (Microfeet 2). This measures will be taken across a knee flexion. Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
Primary Guteus maximus isometric strength Isometric muscle strength (Kg) will be evaluated by means of a digital dynamometer (Microfeet 2). This measures will be measured by means of hip extension. Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
Primary Height on counter movement jump Height (centimeters) on counter movement jump will be assessed using a mobile application called "My jump". Its data has been used as an indirect indicator of explosive muscular strength of lower limb Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
Primary Time flight on counter movement jump Time flight (milliseconds) on counter movement jump will be assessed using a mobile application called "My jump". Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
Primary Force on counter movement jump Force (newtons) on counter movement jump will be assessed using a mobile application called "My jump". Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
Primary Back chain flexibility Changes Back chain flexibility is going to be assessed by means of modified Back Saver Sit and reach test (centimeters). Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
Primary Hamstring flexibility changes Hamstring muscles flexibility will be assessed using the passive knee extension test (degrees) by means of goniometer. Change between baseline (immediately before intervention) and post intervention (immediately after intervention); Change between baseline (immediately before intervention) and 30 minutes after intervention]
