Effect of Two Different Mobilization Techniques in the Treatment of Low Back Pain

Non-specific low back pain (NSLBP) is extensively musculoskeletal conditions, where manual therapy techniques have been widely employed in its management, but their short term efficacy in chronic low back pain still need more investigations. Objective: This study aimed to discuss the SNAG versus Maitland techniques in the management of NSLBP. Methods: 60 patients with chronic NSLBP will share in the study. Sessions will be conducted 3 times per week for 4 weeks. The outcomes will be evaluated for pain by the numerical rating pain scale (NPRS), disability through Oswestry Disability Index, flexion range of motion by back range of motion device, postural stability by Biodex system will be assessed at baseline, immediately post-intervention, and at a four-week follow-up

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

Inclusion criteria

  • Adults aged 25 to 40 years.
  • Diagnosed with chronic NSLBP persisting for more than three months.
  • Pain intensity between 3 to 6 on the Visual Analog Scale (VAS) during lumbar extension in a sitting position.
  • Oswestry Disability Index (ODI) score between 20% to 40%.
  • Restriction of the movement only in flexion ROM with the ability to perform at least 40° of trunk flexion.

Exclusion criteria

  • Specific causes of low back pain (e.g., herniated disc, spinal stenosis).
  • History of spinal surgery or trauma.
  • Neurological deficits or systemic diseases affecting the musculoskeletal system.
  • Pregnancy.
  • Current participation in other physiotherapy programs.

Treatment and study plan

Maitland

Procedure

Maitland technique therapy, which consists of passive mobilizations applied to the lumbar facet joints in an anterocranial direction while the patient is in a prone lying position

SNAG

Procedure

The technique involves applying a sustained glide to the lumbar facet joints while the patient is in a sitting position, and the pelvic girdle will be stabilized by a belt. Then the therapist will ask the patient for active forward flexion of the spine while the pressure on the facet joint is maintained during the movement till its end

Other names: sustained natural apophyseal glide

Primary outcomes

  1. Numeric Pain Rating Scale

    Time frame: 4 weeks

    The NPRS will be used to evaluate the level of pain by selecting a number on a rating scale, ranging from 0 (no pain) to 10 (worst and unbearable pain).

Secondary outcomes

  1. Functional disability

    Time frame: 4 weeks

    Assessed by the Oswestry Disability Index (ODI) where according to the scale the disability will be indicated as follow: 0-4 no disability, 5-14 mild disability, 5-24 moderate disability, 25-34 severe disability, and 35-50 complete disability

  2. Lumbar flexion range of motion

    Time frame: 4 weeks

    Measured using a Back range of motion (BROM)

  3. overall stability index (OSI)

    Time frame: 4 weeks

    Repositioning error evaluated through proprioceptive testing provided by the Biodex Balance System, no need for cut off) as the measurement differences will be compared.
