Single Leg Squat Performance in Physically and Non-physically Active Individuals

Single-leg squat (SLS) is a functional test visually rated by clinicians for assessing lower limb function as a preventive injury strategy. SLS clinical rating is a qualitative evaluation and it does not count objective outcomes as kinematics data and surface electromyography (sEMG) assessment. Based on the SLS rating, the aims of this study were (i) to determine the clinical rating agreement among six raters and (ii) to assess kinematic and sEMG predictors of good SLS performance in physically and non-physically active individuals.

Treatment and study plan

performance of the single leg squat task

Other

The single-leg squat (SLS) is a clinical functional test commonly used to evaluate clinical abnormal movement patterns of the lower limbs in terms of kinetic chain or co-ordinating muscle activity. This scale accounts for the assessment of five dimensions: overall impression, trunk posture, pelvis in space, hip joint motion and knee join motion. The SLS is potentially promising as a functional test since it involves both daily activity and athletic task.

Other names: clinical assessment

Primary outcomes

  1. reliability of the clinical assessment

    Time frame: Baseline

    intra- and inter-rater reliability for six clinicians when performing the SLS clinical rating assessment

  2. reliability of the clinical assessment

    Time frame: 2 weeks after the first evaluation

    intra- and inter-rater reliability for six clinicians when performing the SLS clinical rating assessment

  3. reliability of the clinical assessment

    Time frame: 1 month after the first evaluation

    intra- and inter-rater reliability for six clinicians when performing the SLS clinical rating

Secondary outcomes

  1. kinematic predictors

    Time frame: Baseline

    The following kinematic variables were considered during the single-leg squat: ipsilateral hip flexion in the lateral plane, hip internal rotation, hip adduction, pelvic obliquity, knee flexion (lateral plane) and medio-lateral displacement (frontal plane).

  2. sEMG predictors

    Time frame: Baseline

    The surface Electromyography (sEMG) activity of the following muscles were assessed: tensor fasciae latae, rectus femoris, adductor longus, gluteus maximus and transversus abdominis.
