Condition: Disk Herniated Lumbar; Coordination Lack; Muscle Weakness
MeSH terms: Intervertebral Disc Displacement; Muscle Weakness; Ataxia; Hernia
Study type: Interventional

Summary: 
      Intervertebral disc degenerations are the most important cause of chronic low back pain
      resulting in job loss and associated socio-economic problems in developed and developing
      industrial countries 1. More than 40% of the Turkish population has experienced low back pain
      at least once in their life 2. Intervertebral disc degenerations Lumbal Disc Herniation
      (LDH), which is frequently represented, can cause motor and sensory losses in the lower
      extremity by compressing the spinal nerves. Lumbar disc surgery procedure is inevitable in
      case of advanced functional losses in the related sensory dermatomes and muscles after LDH.
      Lumbal disc surgeries are performed for the purpose of decompression of nerve pressures on
      nerves due to advanced disc herniation. they suggest 4.

      One of the most common LDH problems in the community is low foot problems due to weakness of
      the tibialis anterior muscle, which occurs due to L4-L5 disc herniation, and the accompanying
      functional disorders. In disc herniations at this level, the activation of the tibialis
      anterior muscle, which is compressed by the nerve root, decreases compared to the medial
      gastrocnemius muscle, where it works as an antagonist, and this leads to functional
      limitations, especially in gait and balance activities.

      Spinal stabilization exercises are a concept that emerged from the idea that exercise is
      important for the provision and preservation of functionality of people with low back and
      back pain due to LDH. According to this exercise approach, muscles are of great importance in
      providing lumbar region stability. These muscles are classified as general (global)
      stabilizing muscles, which are dynamic, phasic, and power-producing muscles, and regional
      (local) stabilizing muscles, which are postural, tonic, and stabilizer muscles. The main
      muscles responsible for spine stabilization are multifidus, transversus abdominus and pelvic
      floor muscles 6. It is argued that increased lumbo-pelvic motor control thanks to spine
      stabilization facilitates lower extremity activities, especially flexion and extension
      movements in the sagittal plane. Patients with LDH who increase their motor strength can use
      lower extremity movements more functionally.

      The aim of this study was to (1) determine the activation rates of the tibialis anterior and
      medial gastrocnemius muscles during different functional activities in the lower extremities
      affected and unaffected by LDH, (2) to compare the rates of the affected extremity to the
      rates of the healthy extremity during coactivation of the transversus abdominus and
      multifidus muscles (spinal stabilization basic exercise). to determine whether it is close or
      not. According to the hypothesis of this study, the researchers thought that the functional
      activities performed together with the activation of the transversus abdominus and multifidus
      muscles would show coactivation behaviors at a rate closer to the healthy extremity.
