Proprioceptive Neuromuscular Facilitation in the Flexibility and Strength of Flexor Muscles and Hamstrings
Condition: Proprioceptive Disorders
MeSH terms: Somatosensory Disorders
Study type: Interventional

Summary: 
      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.
    


Intervention name(s): Experimental; Control
Intervention type(s): Other; Other
Intervention description(s): 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.; 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.
