About this study

Official title: Efficacy of an Intervention by Proprioceptive Neuromuscular Facilitation in the Flexibility and Strength of Flexor Muscles and Hamstrings, in Federated Football Players From 18 to 30 Years Old. A Randomized Clinical Trial.

Introduction: The loss of normal values of ROM due to the lack of flexibility and strength in the hip flexors, quadriceps and hamstrings in soccer players can cause a loss of mobility of the hip and knee joint. Proprioceptive neuromuscular facilitation is an active-assisted stretching technique used to improve flexibility and therefore the ranges of joint mobility.

Aim. To assess the effectiveness of an intervention by proprioceptive neuromuscular facilitation in the improvement of flexibility and strength in the hamstring, hip flexor and quadriceps musculature compared to conventional stretches in football players.

Study design. Randomized, multicentric, single-blind clinical study. Methods. The 30 players will be randomly assigned to the study groups: experimental (proprioceptive neuromuscular facilitation and static stretches) and control (static stretches). The treatment will last 6 weeks, with two sessions a week of 5 minutes each. The study variables will be the range of hip mobility (using goniometry), hamstring flexibility (using the EPR test, inclinometer) and the strength of hip flexors, quadriceps and hamstrings (through the RM test). A descriptive statistical analysis will be carried out calculating the main statistical characteristics and after calculating the normality of the sample (test Kolmogorov- Smirnov), the differences between evaluations in each group (t-student test) and the intra- and intersubject effect will be calculated (ANOVA of repeated measures).

Expected results. Improved hip mobility, hamstring flexibility and strength in hip flexors, quadriceps and hamstrings muscles.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ExperimentalOther

    Also called Proprioceptive neuromuscular facilitation

    The technique will be carried out with the subjects in the positions of supine, prone and lateral position, for the flexor muscles of the hip, hamstrings and quadriceps, where the musculature and the joint to be treated will be taken to a range of functional mobility. The subject will be asked to perform an isometric contraction, with a series of 3 seconds for sustained contraction and a rest between contraction of 2 to 3 seconds after activating the Golgi apparatus, making an inhibition of the stimulus and bringing the joint and muscle to the highest possible range of motion without pain.

  • ControlOther

    Also called Muscle stretching

    The active stretching technique will be performed for the hip, quadriceps and hamstring flexors with a voluntary antagonist activation to relax the agonist muscle, holding the movement to be performed for 30 seconds to stimulate the neuromuscular spindle and produce a relaxation of the muscle fibers.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline flexibility of the hamstring muscles after treatment and at month

    The measurement instrument to measure the flexibility of the hamstring muscles is the passive elevation of the straight leg with an inclinometer (model ISOMED, Inc., Portland, OR) to be placed on the tibia (as distal as possible). The physiotherapist will maintain the extension of the knee and the leg will be lifted by the evaluator to a hip flexion, until the subject indicates pain in the hamstring muscles, when the evaluator perceives hip flexion restriction or when a posterior pelvic tilt occurs. The contralateral knee of the subject will remain in extension. The unit of measurement of the test is the maximum angle read from the inclinometer at the point of maximum flexibility, in degrees, with the normative range of 75 to 80 degrees (the greater the degree of flexibility, the greater the flexibility).

    Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit

Secondary outcomes (2)
  1. Change from baseline the range of motion of hip after treatment and at month

    The range of motion of the hip will be evaluated using a universal long arm goniometer. The hip flexion will be measured with the goniometer as the deviation from the neutral zero position in which the lower extremity and the trunk are in the horizontal plane. The fixed arm of the goniometer will be aligned on the horizontal axis of the body, while the mobile arm of the goniometer will be aligned on the lateral midline of the thigh, placing the goniometer support axis on the greater trochanter. Hip adduction and hip abduction will be measured from the neutral zero position in which the longitudinal axis of the thigh is perpendicular to the transverse line through the anterior superior iliac spines of the pelvis. The contralateral leg will be hanging over the edge of the stretcher. The unit of measurement for this test is the grade, with a range of normative movement from 0 to 50 degrees (the higher the graduation, the greater the mobility of the hip).

    Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit

  2. Change from baseline strength of upper limbs after treatment and at month

    The strength of upper limbs will be measured with the 1RM test. This test is defined as the maximum repetition with the heaviest load through a full range of motion. To calculate the 1 RM, the indirect relationship methods of lifting a submaximal load with a full range of motion to failure will be used. From this action a mathematical model related to the load and the number of repetitions until the failure will be made, obtaining a value of force. The unit of measurement of this evaluation is the kilogram (a higher value indicates a greater performance in the strength of lower limbs)

    Measured: Screening visit, within the first seven days after treatment and after one month follow-up visit

Questions about this trial

What is this clinical trial studying?

A study testing Experimental in people with Proprioceptive Disorders, run by Investigación en Hemofilia y Fisioterapia at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline flexibility of the hamstring muscles after treatment and at month (time frame: Screening visit, within the first seven days after treatment and after one month follow-up visit). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2020.
