Study: NCT04763798

Intervention type: OTHER
Group type: EXPERIMENTAL
Intervention: Straight-leg-raise (SLR)
Description: The stretched lower limb was on a mobile support and the contralateral limb was stabilized with a belt on the bench. For the SLR, the knee was kept in full extension and then, hip flexion was performed until a marked resistance. All stretching modalities were applied until a marked resistance was felt by the physical therapist (end-feel) or until the point of maximal tolerance referred by subjects.The stretch lasted 30 seconds followed by 15 seconds rest period and the procedure was repeated 5 times. Each stretching was applied for 5 minutes

Intervention: Passive Knee extension test (PKE)
Description: The stretched lower limb was on a mobile support and the contralateral limb was stabilized with a belt on the bench. For the PKE, the hip was kept in 90º flexion and then, knee extension was performed. All stretching modalities were applied until a marked resistance was felt by the physical therapist (end-feel) or until the point of maximal tolerance referred by subjects.~The stretches lasted 30 seconds followed by 15 seconds rest period and the procedure was repeated 5 times. Each stretching was applied for 5 minutes

Intervention: Maximum hip flexion (MHF)
Description: The stretched lower limb was on a mobile support and the contralateral limb was stabilized with a belt on the bench. For MHF, a maximal hip flexion was performed and then, knee extension was applied. All stretching modalities were applied until a marked resistance was felt by the physical therapist (end-feel) or until the point of maximal tolerance referred by subjects.~The stretches lasted 30 seconds followed by 15 seconds rest period and the procedure was repeated 5 times.
