KT was applied to the symptomatic shoulder of participants.

Ice packs were applied to the symptomatic shoulder of participants.

KT was applied to the symptomatic shoulder at the end of the baseline assessment by a certificated physiotherapist with over ten years of experience in Kinesio taping. After three days, participants were re-evaluated. KT application has been made according to the protocol for rotator cuff impingement or tendonitis including inhibition and correction techniques.

Numerical Rating Scale (NRS): The pain severity was assessed using the NRS, for which a subject was asked to rate his/her perceived pain. A 11-point NRS from 0 to 10 which 0 means no pain and 10 means the worst possible pain was scored during night, rest, and activity.

Disability of the Arm, Shoulder and Hand (DASH) Questionnaire): DASH is a self-reported questionnaire designed for evaluating the functional level of upper extremity. It is a 30-item scale that addresses difficulty in performing various physical activities that require upper extremity function (physical function, 21 items); symptoms of pain, activity-related pain, tingling, weakness, and stiffness (pain symptoms, 5 items); or impact of disability and symptoms on social activities, work, sleep, and psychological well-being (emotional and social function, 4 items). Each item is scored between 1 and 5. A score of 1 indicates no strain, and a score of 5 indicates inability to perform the specified activity.

Shoulder Pain and Disability Index (SPADI): The SPADI is a self-administered questionnaire developed to measure the pain and disability associated with shoulder pathology in people with shoulder pain of musculoskeletal, neurogenic, or undetermined origin. It consists of 13 items that assess two domains: a 5-item subscale that measures pain and an 8-item subscale that measures disability. The items of both domains were scored on a numerical rating scale ranging from 0 to 10, where 0=no pain/no disability and 10= worst pain imaginable/so difficult required help.

Range of Motion (ROM): The active range of motion (ROM) of the affected shoulder, including flexion, abduction, external rotation, and internal rotation, was assessed using a universal goniometer following the protocol reported by the American Academy of Orthopaedic Surgeons (AAOS)
