Analyzing Gait Pattern Using Insole-type Gait Analyzer in Patient With Gait Disturbance

Primary outcomes

1. Timed up and go test (TUG)

   Time frame: TUG test session will last approximately 5 minutes. and TUG test will be performed at baseline.

   The participants will wear insole-type gait analyzer and undergo the Timed Up and Go test.

   The above test assesses walking speed along with balance ability during walking, and this is performed as follows.

   • A 46 cm high armrest chair, a color cone is placed at a distance of 3 meters from the chair and the subject is instructed to sit on the chair.
   • In the preparation phase, the subject leans against the chair backrest and places his/her arms on the armrests, then stands up on the instruction "Start", walks 3 meters, turns around the color cone, returns to the starting point and sits down on the chair.

   • Data Verification The measurement values of the accelerometer and pressure sensors recorded in the insole-type gait analyzer will be examined to determine the presence of missing or outlier data. The investigators will explore the data collection frequency and analysis methods to extract clinically significant data.

2. Korean version of Sarcopenia Screening Questionnaire

   Time frame: This K-SSQ session will last approximately 1 minutes, it will be performed at baseline.

   Questionnaire that evaluates the decrease in muscle strength and functional performance along with a decrease in muscle mass and it is highly related to aging and chronic diseases. The evaluation method is conducted by having the examiner ask the subject about the following questionnaire, and the scores for the answers are recorded.

   It consists of 5 questions, and each question is scored 0-2 points. The higher the score, the higher the risk of sarcopenia. If the score is 4 or higher, sarcopenia may be suspected.

3. Korean version of the International Physical Activity Questionnaire (K-IPAQ)

   Time frame: This K-IPAQ session will last approximately 3 minutes, it will be performed at baseline.

   Tests that assess various aspects of an individual's daily physical activity16 and it can provide information about activity level. The examiner questions the subject based on the questionnaire below, records related information, calculates the total activity time and intensity, and classifies it as 'low', 'medium', and 'high'.
