Objetive. The objective of this randomized clinical trial is to check the acute effects of manual pressure and traction technique on balance and plantar footprint variables. Design A Single-blind clinical study with two groups. Setting Private practice Participants Forty healthy participants (28 females and 12 males) were recruited to carry out a single-blind study. Interventions. Experimental group performed a bilateral plantar fascia manual pressure and traction technique. Control group performed a tactile stimulation. The position of the participant, the therapist and the time of application of the techniques (5 minutes) were the same for both interventions. Main Outcome Measures. We measured stabilometry variables and static footprint. The footprint variables were divided in rear, middle and front foot areas. Results Significant differences were found in stabilometry variables. There was an improvement in experimental group at X displacement with eyes open (p=0.014) and surface eyes closed (p=0.046) variables. Conclusions After technique the experimental group improved the stabilometry variables, specifically, surface with eyes closed and X displacement with eyes open. The static footprint variables have not shown differences after the technique compared to the control group.

The purpose of this study was to analyze the immediate effects of an intermittent plantar flexion static-stretching protocol on balance and plantar pressures.The study included a sample size of 24 healthy participants (21 female and 3 male). Participants were 32.20 ± 8.08 years, 166.20 ± 8.43 cm, and 62.77 ± 9.52 kg. All participants performed an intermittent plantar flexion static-stretching protocol. Five sets (60 seconds intermittent stretch; 15 seconds for the rest time) of a passive plantar flexor stretching (70% to 90% of the point of discomfort) were performed. Static footprint analysis and a stabilometry analysis were performed before and after stretching. A P value.05 with a CI of 95% was considered statistically significant for all tests.Intermittent ankle plantar static stretching resulted in a significantly greater forefoot surface contact area and lower rear foot medium and maximum plantar pressures. In addition, static stretching caused a lower displacement of the center of pressure for both eyes open and eyes closed conditions.An intermittent plantar flexor static-stretching protocol improved balance and reduced rear foot plantar pressures (maximum and medium pressures).
