Primary dependent study variables and their measurement instruments

PRIMARY DEPENDENT VARIABLES	MEASUREMENT INSTRUMENTS/INTERPRETATION OF RESULTS
- Treatment adherence:	- yes/no Calculation of the percentage of treatment compliance for therapeutic adherence. PC = number of activities performed by patient/number of activities prescribed by the therapist *100. If PC is equal to or over 80%, it is considered that there was good treatment adherence. If less, no.
	-Physical state of the limb (inspection and palpation of the affected area). Photographs will be taken of the limb [42].
- Skin hydration: - Skin lesions: - Nail lesions: Yes / no - Induration / Fibrosis: Yes / no - Pitting edema: Yes / no - Stemmer: Yes / no	Normal/ dry/sweating Yes / no Yes / no Yes / no Yes / no Yes / no
	-Visual analogue scale (VAS), where 0 is no pain, heaviness or tension and 10 is maximum pain, heaviness or tension.
- Pain: - Heaviness: - Tension:	VAS 0–10 VAS 0–10 VAS 0–10
- Shoulder joint rotation:	Degrees with goniometer: Flexion___/Abduction___/External rotation___
	-Volume, through circometry (manual measurement of perimeters of the limbs with a tape measure, the value of the volume is approximate and volume is calculated using the Kuhnke formula Vol = (C1 2 + C2 2 + … Cn 2)/ π)) [43–45].
- Degree of lymphedema (according to % of volumetric):	_Grade 1 or mild: difference in circometry less than 4 cm (in volume 10–25%) with respect to the healthy arm. _Grade 2 or moderate: difference in circometry between 4 and 6 cm (in volume 25–50%) with respect to the healthy arm.
- Volumetric %: - Difference in volume in % between both extremities: - Volumetric in ml:	Vol = __% D = __% Vol = __ml *an edema reduction of 150 ml over the basal value is required in order to be considered clinically relevant
- Function of the upper limb/activity performance.	- Value of Quick Disabilities of the Arm, Shoulder and Hand (Quick DASH) [21], with transcultural, reliability, validity and sensitivity adaptation to changes of its extended version in 2006 [46, 47]. - Quick DASH value = __% (the result is calculated as a percentage, the higher the obtained result, the greater the disability or symptom)
- Treatment costs	Sum of expenses: -Prescription of compression garment: Yes (specify type and cost ______________) / NO - Type of bandaging used: proprioceptive / multi-layer (number of rolls used per price of each of the same) - Total number of treatment hours with therapist: 5/10/other (which:___) (number of hours used per professional hour price)
