Clinical Trial Summary

Anterior Knee Pain or Patellofemoral Pain (PFP) is one of the most common disorders that affecting knee in the physically active population, being a condition that typically presents as diffuse knee pain in the anterior region and retro- or peri-patellar area, mainly in activities that increase compression force in patellofemoral joint, such as squatting, running, stair ascent and descent. The overall prevalence of PFP has been reported as between 15-45% of the population, and its incidence is higher among women. The literature cites as etiology of PFP the ocorrence of dysfunctions in the local (knee), proximal (trunk, pelvis and hip complex) and distal (ankle and foot regions) factores. Actually, there is a lack of studies that investigate the interventions influences on distal factors in outcomes clinical in persons with PFP. Thus, the aim of this study is analyze the effect of ankle mobilization techiniques in ankle dorsiflexion range of motion closed kinetic chain in women with patellofemoral pain and with dorsoflexion restriction.

Description:

The sample of this study will be formed by 117 lower limbs of women with PFP who have ankle dorsoflexion restriction, divided into three groups. Each group will contain 39 lower limbs and receive an ankle mobilization technique with a specific sense of mobilization. The group nominated GAP will receive an mobilization technique with slip sense from anterior to posterior. The group nominated GPA will receive an mobilization technique with slip sense from posterior to anterior. The group nominated GPA-AP will receive an mobilization technique with slip sense both from posterior to anterior and from anterior to posterior.

Each group will receive a single intervention, which will consist of four sets of five repetitions of the ankle mobilization technique (according to the specific slip direction of each group), with rest time between series of one minute. In the group GPA-AP, to standardized the sequence of mobilization, the first two sets will be performed with slip sense from anterior to posterior, and the last two sets will be performede with slip sense from posterior to anterior. There will be randomisation allocation of individuals in the groups and because of the nature of the interventions only the evaluator may be blind.

The Kolmogorov - Smirnov test is used to verify the data distribution normality. The characterization of the participants is performed by means of descriptive statistical analysis. Parametric or non-parametric tests will be used according to the data distribution normality for comparison between groups at baseline. The evaluator blinding will be tested using the chi -square test by comparing the randomization code with the evaluator opinion. The difference between the groups and their respective confidence intervals will be calculated by linear mixed models using interaction term of "time versus group".

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Range of motion of ankle dorsiflexion.	Closed kinetic chain evaluation to find the greatest distance between the foot and the wall without compensations.	Immediatly after intervention day.
Secondary	Range of motion of ankle dorsiflexion.	Closed kinetic chain evaluation to find the greatest distance between the foot and the wall without compensations.	Two days after intervention day.
Secondary	Angle of projection in the frontal plane in the lower limb.	Will be measured during the conduct of the Forward Step-Down Test through captured footage using a digital camera that will be positioned within two meters of the participant.	Immediatly and two days after intervention day.
Secondary	Numeric Pain Scale.	Pain was assessed by use of an Numeric Pain Scale of eleven point, where zero corresponded to no pain and ten corresponded to worst imaginable pain	Immediatly and two days after intervention day.
Secondary	Global Effect Perception Scale for Treatment	Global Effect Perception Scale for Treatment was assessed by use f an numeric scale of eleven point, where the lowest score corresponds to the extremely worst condition and the highest score corresponds to the fully recovered condition.	Immediatly and two days after intervention day.
