Flossing Protocol and Manual Therapy in Young Subjects With Recurrent Ankle Sprains

Study Overview
=================
Brief Summary
-----------------
The most frequent lateral ankle sprain mechanism consists of talocrural plantarflexion added to a subtalar inversion. The anterior talofibular ligament, in plantar flexion, suffers maximum stress, being very sensitive to injury mechanisms with inversion of the foot, being the cause of up to 70% of sprains. The risk of injury recurrence must be taken into account. In sports practice, this percentage of recurrence is especially relevant. Randomized clinical study. Participants will be randomized to a control or experimental group. The dependent variable will be the range of motion in ankle dorsiflexion. Secondary variables will be pressure pain threshold, and stability of the foot and ankle. Three evaluations will be carried out: before the start of the study (T0), after the intervention (T1) and after a 4-week follow-up period (T2). All evaluations will be performed by one evaluator, blinded to player assignment The intervention consists of the application of a treatment protocol based on an initial active warm-up consisting of 3 active exercises, walking for 1 minute performing slow and controlled movement of the ankle, raising the heels, 15 repetitions, dorsiflexion of the ankle in the standing position. gentleman, 15 reps. Subsequently, the floss band will be placed, performing again the 3 active warm-up exercises with the band on. After this, the passive manual techniques will be carried out for the remaining time, removing the flossing at the end of the latter, and actively mobilizing again.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline ankle range of motion after treatment and at 4 weeks | Using an analog goniometer, range of motion was measured. This instrument has shown excellent reliability. The joint range in plantar and dorsiflexion was measured. The unit of measurement is degrees (the higher the degree, the greater the mobility). | Screening visit, within the first seven days after treatment and after four weeks follow-up | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline pressure pain threshold treatment and at 4 weeks | Pressure pain threshold will be measured with a pressure algometer (Wagner FDIX model, Wagner Instruments, CT, USA). Pressure will be progressively applied until the sensation begins to be painful. Pressure pain threshold will be measured bilaterally in the region ventral to the lateral malleolus. | Screening visit, within the first seven days after treatment and after four weeks follow-up | 
| Change from baseline foot and ankle stability after treatment and at 4 weeks | The biomechanical analysis of gait and balance will be evaluated using an Rs Scan® pressure platform and a FootScan® pressure measurement system. This scientific version biomechanical examination device measures plantar pressure using an X-Y array of resistive pressure sensitive sensors that are sequentially scanned. The system records pressure data when the subject is standing or walking on the platform. The measurements will be made with the basic platform of 0.5m with 4096 sensors with resistive technology and 300Hz data acquisition frequency. The biomechanics of gait will be analyzed with the analysis of the probes and the static balance in a time of 30 seconds. | Screening visit, within the first seven days after treatment and after four weeks follow-up |
