Evaluation of a visual feedback system in gait retraining: a pilot study

Area of Science:

• Biomechanics
• Gait Analysis
• Rehabilitation Technology

Background:

• Abnormal frontal plane gait patterns, such as Duchenne or Trendelenburg gait, are associated with various underlying diseases.
• Assessing and correcting these gait abnormalities is crucial for improving patient mobility and function.

Purpose of the Study:

• To investigate the immediate effects of a visual feedback system on frontal plane pelvic and trunk movements.
• To determine the potential utility of this system for patients undergoing total hip replacement (THR) rehabilitation.

Main Methods:

• A pilot study involving 24 women (45-65 years) divided into a control group (CG) and an intervention group (IG).
• Kinematic data of pelvis and trunk movements in the frontal plane were collected using a motion analysis system (MVN, XSens).
• Measurements were taken before (M1) and during (M2) the use of a real-time visual feedback system.

Main Results:

• Significant differences in mean inclination of pelvis and trunk movements were observed between the IG and CG in M1.
• These significant differences were not detected in M2 when the visual feedback system was in use.
• The intervention group showed an improvement in movement patterns while utilizing the feedback system.

Conclusions:

• Visual feedback systems can effectively improve frontal plane pelvis and trunk movement patterns, particularly in individuals with abnormal gait.
• This technology holds promise for clinical applications in gait rehabilitation, especially for post-surgical patients.
