The goal of this experimental study is to evaluate the effect of a therapeutic exercise program based on upper limb plyometric exercises in breast cancer patients and breast cancer survivors to determine changes in upper limb functionality.
The main question it aims to answer is: Does upper limb plyometric strength exercise improve upper limb dysfunctions in breast cancer patients and survivors? The researchers will compare the effects of plyometric exercise with the effects of strength training exercise to determine whether plyometric exercise improves shoulder dysfunctions in breast cancer patients and survivors.
Participants from the Pontevedra group will undergo the intervention using plyometric exercise (Experimental Group), while those from the Vigo group will perform strength training exercise (Control Group). They will complete two sessions per week for six weeks. Outcome variables related to upper limb functionality will be assessed at baseline and after the intervention.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| plyometric exercise group | Experimental | this group will perform a program of different exercises focused on the upper limb and shoulder girdle based on plyometric exercises. |
|
| Strength training exercise group | Experimental | This group will perform a strength training program by performing different exercises focused on the upper limb, lower limb and trunk muscle strengthening. |

|---|---|---|---|---|
| plyometric exercise | Other | Upper limb plyometric exercise (proprioceptive neuromuscular facilitation of extensor and flexor pattern, external rotation exercise at 90º-90º, chest throw, external rotation and overhead and wall flexion). |
| Measure | Description | Time Frame |
|---|---|---|
| Change from Baseline in pain and activities of daily living, range of motion in flexion, abduction, external rotation, and internal rotation and sustained submaximal strength at six weeks | Constant-Murley Score (Spanish version): Minimum and maximum values: 0 to 100. The scoring system includes 35 points for subjective measurement and 65 points for objective measurement. Interpretation: Higher scores indicate less disability. | From enrollment to the end of treatment at 6 weeks |
| Change from Baseline in Disability Arm Shoulder and Hand at six weeks | Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire: Minimum and maximum values: The Spanish version of the DASH is a 30-item questionnaire where each question offers response options ranging from "no difficulty" or "none," scored as 1, to "unable" or "very severe," scored as 5. The total score ranges from 0 (no disability) to 100 (severe disability). At least 27 out of 30 questions must be completed to calculate a score. The values assigned to each response are summed and divided by the number of responses to obtain an average score from 1 to 5. This value is then transformed to a 0-100 score by subtracting 1 and multiplying by 25. This transformation facilitates comparison with other tools that report results on a 0-100 scale. Interpretation: Higher scores indicate greater disability. | From enrollment to the end of treatment at 6 weeks |
| Change from baseline in the maximum grip muscle strength at six weeks | Minimum and maximum values: Maximum grip strength is measured using dynamometry and determined by the average of three measurements at each time point. Interpretation: Higher scores indicate less disability. | "From enrollment to the end of treatment at 6 weeks" |
| Change from baseline in the proprioception at six weeks | Assessed by determining force sense: First, maximum grip strength is measured, and the participant is then asked to reproduce half of that maximum force. Three measurements are taken, and the one closest to the target is recorded. Additionally, proprioception is assessed by determining joint position sense (statesthesia): The examiner moves the subject's wrist, and the subject is asked to memorize the position to reproduce it later with their eyes closed. In a second phase, with eyes covered, the subject is asked to reach the previously indicated position from a starting point. Any deviation from the neutral position is measured using a goniometer. One measurement is taken for each position, and the closest one is recorded. |

| Change from baseline in the maximum isometric upper limb strength at six weeks | The variable of maximum isometric upper limb strength will be measured using the MicroFET2 in internal rotation, external rotation, and flexion, all performed in the scapular plane. Two measurements of maximum strength will be taken, with 30 seconds of rest between attempts. Each contraction will be held for 3 seconds. The researcher will passively position the upper limb at 0º of shoulder flexion and 90º of elbow flexion, with the force applied to the palmar side of the distal third of the forearm for internal rotation, and to the dorsal side for external rotation. For flexion, the arm will be positioned at 90º of shoulder flexion in the scapular plane and 90º of elbow flexion, with force applied at the distal part of the humerus. Minimum and maximum values: The test is performed twice, and the highest value is recorded. Interpretation: Higher scores indicate better results. | "From enrollment to the end of treatment at 6 weeks" |
| Change from baseline in the circumference measurement: at six weeks | The diameter of the upper limb with lymphedema will be measured using a thin, flexible plastic measuring tape at four anatomical points: the metacarpophalangeal joint, the wrist, 10 cm below, and 10 cm above the lateral epicondyles. The subject will be positioned in a supine position with the arm in the anatomical position, in supination. Three measurements will be taken at each point, and the average of the three measurements will be calculated. | "From enrollment to the end of treatment at 6 weeks" |
| Change from baseline in the kinesiophobia at six weeks | Tampa Scale of Kinesiophobia-11 (TSK-11): The score ranges from 11 to 44. Interpretation: The lowest score (11) indicates no or insignificant kinesiophobia, and higher scores indicate increasing levels of kinesiophobia. | "From enrollment to the end of treatment at 6 weeks" |
| Change from baseline in the Sensation of heaviness of the upper limb at six weeks | Minimum and maximum values: The reported value is recorded using a visual analog scale from 0 to 10, where 0 means no heaviness and 10 means maximum heaviness. Interpretation: Higher scores indicate greater disability. | From enrollment to the end of treatment at 6 weeks |
| Change from baseline in the Sensation of pain of the upper limb at six weeks | Minimum and maximum values: The reported value is recorded using a visual analog scale from 0 to 10, where 0 means no pain and 10 means maximum pain. Interpretation: Higher scores indicate greater disability. | From enrollment to the end of treatment at 6 weeks |
| Change from baseline in the Sensation of tension of the upper limb at six weeks | Minimum and maximum values: The reported value is recorded using a visual analog scale from 0 to 10, where 0 means no tension and 10 means maximum tension. Interpretation: Higher scores indicate greater disability. | From enrollment to the end of treatment at 6 weeks |
