# Table 2 Primary dependent study variables and their measurement instruments

PRIMARY DEPENDENT VARIABLES MEASUREMENT INSTRUMENTS/INTERPRETATION OF RESULTS
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)) [43,44,45].
- 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)
