Villency-Proof of Action: Foot Device, Balance and Sway, Kinematics of Walking

This study involves the use of a newly designed shoe insole device (also referred to as a
foot insole device) similar to various shoe insoles or inserts you can buy at a store or
pharmacy. Healthy participants will wear this insole device in their own athletic/tennis
shoes over the course of one week. There are two key purposes of this study: 1. To determine
how using this insole device for 1 week may effect a healthy individual's balance and
postural sway while standing; and 2. To determine how using this insole device for 1 week may
effect how an individual walks (gait), how hard they hit the ground as they walk, and foot
pressure patterns with each step. Each individual's balance, postural sway, and walking gait
(how you walk) will be analyzed before and after wearing the shoe insole device for the
one-week time period.

Inclusion Criteria:

● Willing to maintain current level of physical activity during the study period of a week
(no increase or decrease of activity level).

Exclusion Criteria:

- Moderate or severe obesity (body mass index >35kg/m2)

- Known diagnosis of cardiovascular, orthopaedic, or neurological conditions,
uncontrolled diabetes, or any condition that impacts normal walking ability

- Any current ankle, knee, hip or low back pain

- Currently using any knee or ankle brace on a regular basis for joint pains

- Severe back pain, prior spinal fusion or spinal deformity that would affect gait

- Major cardiac or pulmonary conditions and any orthopedic limitation that precludes
their ability to independently walk for 10 minutes or longer

- Any major orthopedic injury within the prior 12 months
