About this study

Hamstring muscle injuries are common among highly active individuals. Modern Football is a challenging sport characterized by extremely dynamic and cyclical game motions including numerous bouts of high-speed movements such as accelerating, jumping, and change in direction, all of which are carried out at a high level of physical and technical difficulty. The most common reason for hamstring muscle injury is high-performance intensity. In addition, neuromuscular fatigue, athlete aging, low muscle strength, and hamstring muscle flexibility are also risk factors for hamstring muscle injuries. On the other hand, the main causes of repetition injury to the same muscle are the presence of a previous injury, the size of the muscle tear and the lessening of the long head muscle bundles of the biceps femoris

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Players from the eight clubs in the Iraqi Football League
  • Partially strained hamstring muscle pain when training football or playing a match, identified as:

a. Player reported sudden pain in hamstring muscle c. Without any additional ailment.

  • Based on the clinical signs and symptoms, defined as:
  • Localised pain when palpating of hamstring muscle
  • Localised pain from at least one of the following activities: The Extender, The Diver, and The Glider.
  • MRI-confirmed of partially injured hamstring
  • Available for follow-up

Exclusion criteria

  • Players with other injuries apart from hamstring injuries
  • Players with a recent six-month history of a verified or suspected hamstring injury in the same leg.
  • injured players who are already taking part in another rehabilitation program
  • General contraindications for MRI

Therapeutic Exercises and Ultrasound

Primary outcomes

  1. Time to return to play

    Time frame: Daily session from first therapy session until moment of return to play, up to an average of Six Weeks

    The primary outcomes will be speedy healing, that is, the amount of time needed to recover from an injury in order to fully participate in team training and be available for match selection by the medical staff based on five standardized criteria: 1. no pain on palpation 2. pain free Range of Motion (ROM) 3. Muscular strength evaluation 4. Symptom-free completion of rehabilitation program 5. A specific running test.

Secondary outcomes

  1. Hamstring muscle strength

    Time frame: Daily session from first therapy session until moment of return to play, up to an average of Six Weeks

    Force Sensor from Chronojump. Is an sensor measure of to conduct isometric knee flexion strength testing at two distinct angles: 15° and 90° of knee flexion.

  2. Muscle bio potential signals

    Time frame: Daily session from first therapy session until moment of return to play, up to an average of Six Weeks

    The Electromyogram (EMG) is collected at 1000 Hz with MyoTrace™ 400 . Is a versatile portable handheld, Self-adhesive silver chloride dual snap electrodes for surface attachment will be placed on the leg muscles. The MyoTrace 400 handheld transmitter.

  3. Degree of pain

    Time frame: Daily session from first therapy session until moment of return to play, up to an average of Six Weeks

    Pain visual analog scale (VAS). It is a unidimensional measure of hamstrings pain intensity that consists of a straight horizontal line of fixed length (typically 100 mm) that is graduated. The ends, which were towards the direction of left (worse) to right (best), defined the extreme boundaries of the parameter to be calculated (pain); the higher the score, the more severe the suffering.
