Effects of Rhythmic Stabilization and Mckenzie Techniques on Non Specific Chronic Low Back Pain
Condition: Back Pain
MeSH terms: Back Pain; Low Back Pain
Study type: Interventional

Summary: 
      Non-speciﬁc low back pain is deﬁned as low back pain not attributable to an identifiable,
      known speciﬁc pathology. Non-specific low back pain accounts for over 90% of patients
      presenting to primary care and these are the majority of the individuals with low back pain
      that present to physiotherapy.Objective of this study is to compare the effects of rhythmic
      stabilization and McKenzie technique on pain and function in patients with non-specific
      chronic low back pain
    

Detailed description: 
      Low back pain is the most common musculoskeletal condition worldwide. About 18% of the
      world's population suffers from low back pain and approximately 39% will suffer at least one
      episode of low back pain in their lifetime. Consequently, the costs associated with the
      treatment of patients with low back pain, absence from work , and disability are extremely
      high. The annual worldwide LBP incidence in adults to be 15% and the point prevalence to be
      30% .A sedentary lifestyle with a lack of physical activity results in the loss of muscle
      power and strength and can be a predictor of LBP leading to recurrent LBP .In addition, a
      specific diagnosis of low back pain cannot be obtained in approximately 80% patients with low
      back pain, indicating that patients with low back pain are often diagnosed with nonspecific
      low back pain. Non-specific chronic low back pain (LBP) is a rather common and predominant
      health problem worldwide that affects people of all ages. Nonspecific low back pain is
      defined in the European guidelines for the management of chronic nonspecific low back pain
      (CNSLBP) as low back pain that is not attributable to a recognizable, specific pathology
      (e.g., infection, tumor, osteoporosis, fracture, structural deformity, and inflammatory
      diseases, such as ankylosing spondylitis, radicular syndrome, and cauda equina
      syndrome)Characteristic of chronic nonspecific low back pain are heavy pain, worsening with
      exertion and relieve with rest. In some cases the cause may be sprain or overstretch of a
      ligament or muscles. The endurance of trunk muscles is low in patients with low back pain as
      compared to individual without low back pain. The deep trunk muscles (Transverse Abdominis
      and Multifidus) responsible for maintaining the stability of spine. In other cases the cause
      may be a minor problem with the disc between two vertebrae or a minor problem with a small
      facet joint between two vertebrae. There may be other minor problems in the structures and
      tissues of the lower back that result in pain.The terminology becomes "chronic" low back pain
      when the symptom duration exceeds three months (nCLBP).Chronic low back pain (LBP) represents
      a significant healthcare problem that results in substantial costs to society .It is a
      prevalent condition that leads to increased disability and decreased quality of
      life.Non-specific LBP belongs to the group of musculoskeletal disorders, which include
      diverse conditions affecting muscles, bones, and/or joints of the limbs or the spine.
    

Intervention name(s): Rhythmic Stabilization (RS); McKenzie technique
Intervention type(s): Other; Other
Intervention description(s): Group A includes rhythmic stabilization technique. The patient is in sitting position and faces the physical therapist. The RST program consisted of alternating (trunk flexion-extension) isometric contractions against resistance for 10 seconds, with no motion intended. Subjects performed 3 sets of 15 repetitions at maximal resistance provided by the same physical therapist. Rest intervals of 30 seconds and 60 seconds were provided after the completion of 15 repetitions for each pattern and between sets, respectively. The total duration of RS will be of approximately 33 minutes; McKenzie technique will be guided to conduct four extension exercises and three flexion exercisesAll flexion exercises will be repeated for ten repetitions for two sets. There are three minutes for resting intervals in every set. The McKenzie treatment will lasted for 20-40 minutes.
