The type of cupping therapy will be dry-cupping with moving-cupping (dynamic cupping therapy). The participants will remain in the supine position on a massage table (Posturarte® Olympic), without inclination. Cupping therapy will be performed with a plastic suction cup (5.08 cm in diameter) (K.S. Choi Corp®) and with a pistol for dosing pumps (K.S. Choi Corp®). Prior to the cupping therapy, a small amount of massage cream (ATL®) will be applied throughout the median nerve pathway in order to facilitate the sliding of the suction cup. The cupping therapy will performed with the suction cup sliding with a slow rhythm, insufflation of the suction cup with two pumps for 5 minutes along the median nerve path.

The participants will remain at rest in a supine position on a massage table (Posturarte® Olympic) without inclination for 5 minutes.

dynamic cupping

Data will be collected in two moments: baseline (M0) and after the application of cupping for intervention group or after a resting period for control group (M1).

The M0 will consist in performing the ULNT1 on the dominant upper limb for each participant. The participants will remain in a supine position on a massage table with the body aligned, exposing the test forearm for the placement of the smartphone through an armband. The head and cervical spine will be stabilized at the maximum comfortable lateral inclination using a foam pillow. The ULNT1 sequence used was: (1) maximum contralateral cervical inclination; (2) arm at 90º of shoulder abduction preventing scapular elevation; (3) 90º of external rotation of the shoulder and elbow flexion at 90º (defined as the initial position or 0º of range of motion under test); (4) supination of the forearm; (5) wrist and fingers extension; and (6) elbow extension.
