Shoulder joint Range of Motion

Besides shoulder pain, a key clinical manifestation of shoulder adhesive capsulitis is the progressive limitation of active and passive joint range of motion, which significantly impacts daily living functions. Shoulder joint range of motion can be considered an indicator of treatment effectiveness in frozen shoulder patients. A plastic universal goniometer is a commonly used tool for measuring range of motion. It can be used to measure joint range of motion on various joints. We used this simple tool to measure the anterior flexion, extension, abduction, external rotation, and internal rotation angles of the subject's shoulder joint.

Subjective Pain Intensity: Visual Analog Scale (VAS)

Participants were asked to describe the intensity of their current shoulder pain or soreness. Pain intensity was expressed using the visual analog scale. The visual analog scale is a tool for assessing pain intensity based on the participant's self-reported pain levels and is widely used in clinical practice to track improvements in musculoskeletal pain. Visual analog scale is evaluated using a 10-cm ruler. Patients move an indicator between a "smiley face" (indicating no pain) and a "grimacing face" (indicating extreme, unbearable pain) to reflect their current pain level. The researcher then records the corresponding 0-10 cm score from the back of the ruler.

Muscle strength of shoulder joint

In the clinical manifestations of shoulder adhesive capsulitis, the progressive limitation of active joint range of motion is partly due to insufficient muscle strength. However, the pain in shoulder adhesive capsulitis patients often causes muscle spasms and weakness in the muscles around the affected shoulder, which may also exacerbate the pain and further restrict movement and function. Therefore, the muscle strength of the shoulder joint can also be considered one of the indicators of the cure of shoulder adhesive capsulitis patients. Strength of the shoulder flexors, extensors, abductors, and internal/external rotators is evaluated using a handheld dynamometer. Subjects are verbally encouraged to "push as hard as possible," maintaining a maximum voluntary isometric contraction for 3 seconds. The final recorded value (in pounds) is the average of three trials, with a 1-minute rest interval between each trial.

Disabilities of the Arm, Shoulder and Hand questionnaire (DASH)

The Arm, Shoulder, and Hand Disability questionnaire has been widely used for patients with various upper limb disorders. This questionnaire is reliable and effective for patient populations with various upper limb disorders. The questionnaire mainly consists of a 30-item disability/symptom scale. The questionnaire evaluates upper extremity disability and symptoms using a 30-item module, with each item scored from 1 to 5. A valid total score requires completing at least 27 items. The final score is calculated using the formula: \[(sum of all completed responses / number of completed items) - 1\] × 25. Higher scores indicate greater symptom severity and functional impairment.
