The Relationship Between Gait Velocity and Gait Parameters

February 9, 2017 updated by: Yu Zhang, Guangzhou General Hospital of Guangzhou Military Command
Previous reports have the evidence implicating gait velocity may affect kinematic parameters. However, how the gait velocity will influence kinematic parameters remain unclear. The purpose of this research is to find out kinematic characteristics among different gait velocity. To do this, it will provide a reference for future prospective studies or investigations and make us fully understand the impact of gait velocity.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
