The Influence of Stability Boots on Gait Pattern in Healthy Adults

Study Overview
=================
Brief Summary
-----------------
After an ankle injury like distorsions, fractures or arthrodeses, or congenital defects ankle support limit the range of motion in the joint, help pain relief, control loading of the injured tissues and promote recovery of a normal gait pattern. Gait analysis is applied in orthopedics, sport science and rehabilitation. Numerous measure systems and methods enable accurate analysis of human movement. The study is set to describe and compare the gait analysis of two modifiable stability boots (Ortho® Tri-Phase and the VACOped®) on the standard walking parameters during two conditions (level and ramp walking) in healthy adults and draw comparisons with a control indoor shoe.

Detailed Description
-----------------
The participants are joining one session in the gait lab. Here the are measured during walking with normal shoes and two modifiable stability boots. The duration of a session is typically 3 hours.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| ROM Ankle Joint | Ankle joint motion ROM Sagittal left, during gait | duration of a session is typically 3 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Symmetrie Index | The symmetrie index, represents the % difference step length, index= 2*100*(step length left-step length right)/(step length left+step length right) This measure has no unit. 0 would represent a total symmetric gait. | duration of a session is typically 3 hours |
