About

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.

Full 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".

Trial design

117 participants in 3 patient groups

Group from posterior to anterior (GPA)
Experimental group
Description:
Participants in group GPA will receive a manual therapy intervention, through the technique of mobilization with movement in the ankle joint, with a slip sense from posterior to anterior. The physiotherapist will be positioned in front the participant's ankle, and a belt will be posicioned above the participant's malleolus and around physiotherapist's pelvis. The therapist applies with belt a anterior slip sustained in the tibia of the participant, while the talus are secured with the space between the thumb and the second finger of the hand of both hands on the physiotherapist´s. The participant will be instructed to perform a slow dorsiflexion movement at its maximum amplitude and hold five seconds in that position, returning to the initial position at the end of the five seconds.
Treatment:
Other: Manual Therapy
Group from anterior to posterior (GAP)
Active Comparator group
Description:
Participants in group GAP will receive a manual therapy intervention, through the technique of mobilization with movement in the ankle joint, with a slip sense from anterior to posterior. The physiotherapist will be positioned behind the participant's ankle. An belt will be posicioned above the participant's malleolus and around physiotherapist's trunk. The therapist applies with belt a posterior slip sustained in the tibia of the participant, while the heel and rearfoot are secured with the space between the thumb and the second finger of the hand of both hands on the physiotherapist´s. The participant will be instructed to perform a slow dorsiflexion movement at its maximum amplitude and hold five seconds in that position, returning to the initial position at the end of the five seconds.

Other: Manual Therapy
Group GPA-AP
Active Comparator group
Description:
Participants in group GAP will receive a manual therapy intervention, through the technique of mobilization with movement in the ankle joint, with a slip sense both from posterior to anterior and anterior to posterior. In the group GPA-AP, will be apllied both the procedure described for the group GPA as for the group GAP. To standardized the sequence of mobilization, the first two sets will be performed with slip sense from posterior to anterior, and the last two sets will be performede with slip sense from anterior to posterior.
