Home-based Rehabilitation Monitoring System With Wearable Devices and Self-Report Application

This is a test performed to check the subject's limb muscle mass, and the test method is as follows.

1. Perform body composition analysis based on bioimpedance analysis.
2. To ensure accurate measurement, the test subject is instructed to empty his/her bladder before the test and not to consume caffeinated beverages, eat, drink, or perform strenuous exercise for one hour prior to the test.
3. To correct for muscle mass differences due to height, use the calculated value of limb muscle mass (Appendicular skeletal mass) divided by the square of the height.

Spatiotemporal parametric data of gait collected while the subject is performing a home-based activity wearing an insole gait analyzer, recording total steps, steps per minute(steps/min), gait speed(km/h), distance walked(m), stride length(m), and swing phase rate(%).

A test that assesses the degree of overall cognitive impairment, taking into account a person's level of education, and the test assesses time and place perception, attention and calculation, memory, language, and spatial and temporal organization. The examiner asks questions corresponding to the items on the test sheet below and record a score for the answers.

This is a test used to assess the level of depression in older adults and able to assess quickly the level of depression in the elderly and identify risk. The examiner asks the subject questions according to the questionnaire below, checks items according to the answers, and scores them according to the evaluation method.

This consists of 15 items and is the most commonly used version due to its brevity and ease of use. It can typically be completed in 5 to 7 minutes.

Each item on the GDS is scored 0 or 1, depending on whether the symptom of depression is absent or present according to the patient's response. The total score is calculated by summing up the scores for each item. Generally, a score of 0 to 5 is considered normal, depending on the setting and clinical judgment. Scores of 5 or more suggest depression, with scores of 10 or higher almost always indicative of depression.

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.

Assessment of the subject's walking function. The examiner observes the subject's gait and records a score based on the criteria in the assessment sheet below.

Tests that assess various aspects of an individual's daily physical activity 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'.

A test that evaluates the subject's grip strength, and the evaluation method is as follows.

1. The subject sits in the correct posture and bends the elbows to 90 degrees.
2. Place the handle of the measuring device between the first and second joints of each finger and hold it tightly according to the examiner's instructions.
3. Measure the left and right three times each and record the maximum value.

Test to assess the health status and frailty of elderly and assesses the health and vulnerability of the elderly after the program ends.

The scale ranges from 1 to 9, with each level described through specific criteria that reflect the degree of fitness or frailty, a higher score means poorer health.

It consists of items evaluating exercise ability, self-management, daily activities (work, study, housework, family or leisure activities), pain/discomfort, and anxiety/depression, and examiner evaluates according to the form below.

Participants will be asked to answer each question with 3 items, and a higher score means more health problems, minimum score is 5 and maximum score is 15.

An assessment of nutritional status and risk of undernutrition or malnutrition using questionnaire to assess the nutritional status of a subject, and the examiner records a score based on the criteria in the questionnaire below.

This assessment uses a questionnaire that assesses the nutritional status of subjects to determine their nutritional status and whether they are undernourished or at risk of being undernourished, and the examiner records a score based on the criteria in the questionnaire below.

This is a test that evaluates three areas to assess a subject's lower extremity physical functioning, and it measures and records scores in three areas: balance, getting up from a chair, and walking speed.

1. Balance test: Line up feet in parallel and hold for 10 seconds. If possible, perform this test in a semi-upright position, then straighten feet and repeat 3 times.
2. Chair stand-up test: Perform the stand-up test 5 times from a chair. The examiner measures the time and records the score according to the criteria below.
3. Walking speed test: After having the subject walk 3m, the examiner measures the time and scores according to the criteria below.

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

1. 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.
2. 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.

The above test assesses static and dynamic balance, in which the examiner instructs the subject to perform the 14 movements below and then scores them against a set of criteria.

A test to measure lower extremity strength and power using the isokinetic exercise equipment CYBEX, and 5 repetitions of 60/60 degrees per second and 15 repetitions of 150/150 degrees per second are performed to measure Peak Torque (Nm), Total Work (J), Average power per repetition (W), and Fatigue Index (%) of the lower extremity muscles.

Subjects complete the following five questionnaires before bed, based on the application usage method they were trained on by the examiner. Based on the subject's questionnaire records, the subject's weekly response rate is calculated as n out of 5 responses and n out of 7 days.

The subject conducts the following five surveys before going to bed based on how to use the application trained by the inspector. Based on the subject's questionnaire record, the subject's weekly response rate is calculated with n responses out of 5 and n responses out of 7 days.

The five surveys consist of Mood, Appetite, Sleep Quality and Duration, Activity Level, and Pain.

The subjects of the experimental group return the smart band to the inspector, and fill out a 12-item, 5-point smart band based on the Korean version of the assistance instrument satisfaction test (K-QUEST 2.0), and a satisfaction evaluation questionnaire for the application linked thereto. This questionnaire consists of 12 items to evaluate the satisfaction, and the satisfaction with the assistance instrument and the service used in this regard is expressed in 1-5 points below. If the rest of the items except for very satisfaction are filled out, instruct the subject to fill out the reason. The target group does not do the above. 1: Very unsatisfied. 2: Not satisfied 3: Usually 4: Very satisfied. 5: Very satisfied

The 10-Meter Walk Test16 is used to assess gait speed in patients undergoing rehabilitation for neurological and Severance: H10_250409 musculoskeletal disorders. Participants wear an insole-type gait analyzer and walk a 10-meter straight path at a consistent pace while the time taken is measured to evaluate gait ability.

1. A total straight path of 14 meters is prepared, with the first and last 2 meters serving as non-measurement zones.
2. b) Participants are informed that their walking speed will be measured over the 10-meter section and are instructed to walk at a comfortable pace.
