At Home, Digital Rehabilitation for Patients After Reverse Total Shoulder Arthroplasty

It has a total range of 0 to 100 points (higher means better function). Pain is measured using the Visual Analog Scale (VAS, 10 points) and converted to 50 points, and function consists of 10 questions, each 0 to 3 points, a total of 30 points → converted to 50 points.

The total score is 0-100 (the higher the better), and is composed of pain (30 points), function (40 points), activities of daily living (10 points), and muscle strength (20 points).

The total score is 0 to 12 points (the higher the better the function), and there are 12 questions related to the function, with a yes/no response method. If you answer 'yes', you get 1 point, and the number of 'yes' answers is the total score.

Total 0~100 points (higher means better function), pain (15 points), activities of daily living (20 points), active joint range of motion (ROM) (40 points), muscle strength (25 points): Score is calculated by measuring strength in 90 degrees of abduction.

In addition, an Adjusted Cnstant score will be calculated. This is adjusted for the Normal score (total 100 points) considering differences in shoulder function according to age and gender.

The higher the Visual Analog Scale (VAS, 0~10 points), the more pain there is.

Isokinetic strength: Using an isokinetic strength measuring device called CSMi Medical Solutions, isokinetic strength (internal rotation, external rotation) for each movement is measured according to a standardized protocol. During the test, the subject is seated on a chair and the torso is fixed to the dynamometer. The subject is asked to hold the opposite handle of the dynamometer.

• Flexion: Measure the maximum angle when the arm is raised forward according to the standard protocol.
• Abduction: Measure the maximum angle when the arm is raised sideways according to the standard protocol.
• External rotation: Collect the maximum angle measured when the arm is placed next to the trunk.

Internal rotation: Measure the position of the thumb tip on the spine level when the arm is sent behind the back. Each position is scored. (Thoracic T1-T12 = 1-12 points; Lumbar L1-L5 = 13-17 points; Hip = 18 points)

• Flexion: Measure the maximum angle when the arm is raised forward according to the standard protocol.
• Abduction: Measure the maximum angle when the arm is raised sideways according to the standard protocol.
• External rotation: Collect the maximum angle measured when the arm is placed next to the trunk.

Using a hand-held dynamometer (FGN-20B, SHIMPO, JAPAN), the maximum force (in pounds) is collected and measured in the internal rotation (at side), external rotation (at side), and scaption positions.

• Consists of 9 items on situations that hinder exercise.
• Evaluate how confident you are that you can exercise 20 minutes 3 times a week in each situation on a scale of 10% intervals from 0% (not at all confident) to 100% (very confident).
• Interpret as '0-20% = not at all confident, 20-40% slightly confident, 40-60% = moderately confident, 60-80% = very confident, 80-100 = extremely confident.'

• Collected only in prospective intervention group

The EQ-5D-5L is a standardized instrument developed by the EuroQol Group to assess health-related quality of life across five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has five response levels. Index scores range from less than 0 (worse than death) to 1 (full health).

This measure will be collected only in the prospective intervention group to evaluate changes in perceived quality of life during the rehabilitation process. Retrospective control data are not available for this outcome.
