Key inclusion & exclusion criteria

Inclusion Criteria:

- Participants over 18 years of age.

- Athletes from the university teams in the branches of rugby, soccer, basketball or
tennis.

- Presence of hamstring shortening in one of the two extremities (positive straight leg
elevation test or Straight Leg Raising). It will be considered as a positive test when
the participant, in the supine position, shows tension or discomfort in the posterior
region of the thigh when passively raising the lower limb for any angle less than 80 °
of hip flexion with extended knee. In the event that the participant presents a
bilateral shortening, the limb with the lower elevation will be taken as shortened
hamstrings.

Exclusion criteria.

- Pain when performing hip or knee movements.

- Musculoskeletal injuries such as fractures, sprains, tears, dislocations, contusions,
or joint problems of the lower extremities in the past 3 months.

- Skin disorders such as scars, burns, psoriasis or wounds in the posterior region of
the thighs.

- Neurological signs or symptoms such as tingling, loss of sensation in the lower
extremities (partial or complete), weakness, changes in color or temperature in the
thigh, legs or foot.

- Background or circulatory abnormalities in the lower extremities such as arterial
ischemia, venous insufficiency, embolism, post-phlebitic syndrome, lymphedema or deep
vein thrombosis.

- Joint hypermobility (positive Beighton hypermobility test).

- Intake of medications or anti-inflammatory drug treatment at the time of recruitment
(includes non-steroidal or steroidal anti-inflammatory drugs).

- Allergy to metals.

- Apprehension or fear of the application of electric current.

- Belonephobia (extreme and uncontrollable fear of needles and other objects that can
cause bloody wounds such as pins, knives, pocket knives, syringes, etc.).

Elimination criteria.

- Discomfort during the intervention with electrotherapy that requires stopping
treatment.

- Failure to complete the evaluation protocol (attendance at all scheduled evaluation
sessions).
