# Effects of the Pressure and Traction Technique on the Plantar Footprint and Balance

**Official Title:** Effects of the Pressure and Traction Technique on the Plantar Footprint and Balance Against a Placebo Laser: A Randomized Single Blind Trial

**NCT ID:** [NCT04201795](https://clinicaltrials.gov/study/NCT04201795)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 40
- **Lead Sponsor:** Mayuben Private Clinic
- **Conditions:** Healthy, Foot, Manual Therapy
- **Start Date:** 2019-11-29
- **Completion Date:** 2020-01-29
- **CT.gov Last Update:** 2020-01-31

## Brief Summary

The aim of this clinical trial is to check the effects of manual pressure and traction technique on balance and plantar footprint variables comparing with Laser placebo.

## Detailed Description

Forty healthy subjects wil be recruited for a simple blind study. Participants will be from 1 to 40 years old, not obese. Participants will be randomized into two groups. Experimental group performed a bilateral plantar fascia manual pressure and traction technique. Control group performed a laser placebo. The time duration (5 minutes), position, and therapist were the same for both treatments. The investigators will measure stabilometry variables and static footprint. The footprint variables will be divided in bilateral rear foot, bilateral midfoot, bilateral fore foot.

Measures. Stabilometry will be measured by displacement of the center of pressures in X and Y with eyes open and closed , center of pressure (COP) with eyes open and closed, COP area with eyes open and closed, COP antero-posterior (a-p) and medio-lateral (m-lat) directions with eyes open and closed, and COP speed. Two trials will be recorded for each condition and the order of the conditions will be randomized across subjects, eyes open and eyes closed. Foot plantar pressure and surface area of two static footprints will be measured during bipedal standing. Static plantar pressure will be evaluated by means of maximum pressure, medium pressure and surface area of each aspect of the foot (rearfoot, midfoot, and fore foot).

## Eligibility

- **Minimum age:** 18 Years
- **Maximum age:** 40 Years
- **Sex:** ALL
- **Healthy Volunteers:** Yes

```
Inclusion Criteria:

* Healthy individuals
* Must have no pain

Exclusion Criteria:

* Previous lower extremities surgery.
* History of lower extremities injury with residual symptoms (pain, "giving-away" sensations) within the last year.
* Leg-length discrepancy more than 1 cm
* Balance deficits (determined by oral questionnaire regarding falls)
```

## Arms

- **pressure and traction** (EXPERIMENTAL) — pressure and traction durin 5 minutes will be applied in plantar fascia
- **Laser** (SHAM_COMPARATOR) — Applied during 5 minutes each plantar fascia of sham laser

## Interventions

- **Laser** (OTHER) — laser with no emision will applied
- **pressure and traction tecnique** (OTHER) — pressure and traction in plantar fascia with hands will be applied

## Primary Outcomes

- **static footprint** _(time frame: Through study completion, an average of 1 month)_ — Stabilometry assessment was used and subjects were instructed to stand barefoot on the force platform, participants were instructed to remain in a relaxed standing posture with feet shoulder-width apart and positioned at 30º away from the midline
- **stabilometry variables eyes open** _(time frame: Through study completion, an average of 1 month)_ — Stabilometry assessment was used and subjects were instructed to stand barefoot on the force platform (27), participants were instructed to remain in a relaxed standing posture with feet shoulder-width apart and positioned at 30º away from the midline. During all the examinations, the upper limbs were placed in a relaxed position along the body. The subjects were instructed to stand as still as possible for 30 s, with their eyes open, while concentrating on a point at eye level 2-m away or with their eyes open
- **stabilometry variables eyes closed** _(time frame: Through study completion, an average of 1 month)_ — Stabilometry assessment was used and subjects were instructed to stand barefoot on the force platform (27), participants were instructed to remain in a relaxed standing posture with feet shoulder-width apart and positioned at 30º away from the midline. During all the examinations, the upper limbs were placed in a relaxed position along the body. The subjects were instructed to stand as still as possible for 30 s, with their eyes open, while concentrating on a point at eye level 2-m away or with their eyes closed

## Secondary Outcomes

- **static footprint after intervention** _(time frame: Through study completion, an average of 1 month)_
- **stabilometry variables eyes open after intervention** _(time frame: Through study completion, an average of 1 month)_
- **stabilometry variables eyes after intervention** _(time frame: Through study completion, an average of 1 month)_
