Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
One physiotherapist conducts one-on-one sessions with the patient, gradually increasing stretching until the patient reaches the maximum sensation without pain. Each stretching session lasts for 5 minutes, with a one-week washout period between treatments. Checklists were employed to assess patient interventions.

Two stretching techniques will be applied, one on each leg of the subject. The classic gluteal stretch will serve as the control group, while the stretching using the LightBack device will be the experimental group.

Experimental Group:
The LightBack® machine involves an anterior-posterior (A-P) mobilization of the femur, inducing a stretch of the posterior hip capsule and gluteal muscles. The subject will sit on the machine, bringing the knee towards the chest until it reaches 90º of hip flexion. When the subject feels a stretching sensation without pain, they will hold the position for 10 seconds. Subsequently, they will return to the initial relaxed position for 5 seconds and repeat the sequence 6 times for a total application time of one minute. It's a self-passive mobilization.

Comparator / control treatment
One physiotherapist conducts one-on-one sessions with the patient, gradually increasing stretching until the patient reaches the maximum sensation without pain. Each stretching session lasts for 5 minutes, with a one-week washout period between treatments. Checklists were employed to assess patient interventions.

Control Group: Active control with the other limb-leg
On another day, the subject will perform a gluteal stretch on the other leg. This will be a passive type 1 stretch where the subject, in a supine position, will bring the leg to 90º of hip flexion and external hip rotation with the assistance of the other leg until they feel a stretching sensation. The stretch will have an application time of 30 seconds, and two repetitions will be performed for a total application time of 1 minute. 30 seconds rest between repetitions.

Statistical methods / analysis
The statistical analysis was carried out using IBM SPSS Statistics version 29.0 software for Windows (IBM, Armonk, NY, USA). To assess data distribution, the Kolmogorov-Smirnov test and histogram examination were employed. For parametric variables (p > 0.05), descriptive statistics including mean and standard deviation were presented, while for non-parametric variables (p < 0.05), median and interquartile range were reported.
To compare the baseline characteristics of the two groups, either an independent t-test or Mann-Whitney U test was performed, taking into account assumptions of homoskedasticity and sphericity. If these assumptions were met, a two-way analysis of variance (ANOVA) with a 2 × 2 design was conducted. The effect size was assessed using partial eta squared (?2p), with values of 0.01 interpreted as small, 0.06 as medium, and 0.14 as large. A 95% confidence interval was set to all analyses.

Summary
Brief summary
To determine the effectiveness of a stretch using the LightBack® device vs. a gluteal stretch in healthy subjects' range of motion.
We hypotethize that the LightBack mobilization has a major effect increasing the active and passive hip range of motion, active knee extension and active straight leg raise when compared to gluteal stretch.
