About this study

Official title: Therapeutic Effects of Instrument-assisted Versus Sound-assisted Soft Tissue Mobilization Among Patients With Chronic Non-specific Low Back Pain

Chronic low back pain (CLBP) is the most common medical problem observed among musculoskeletal pain and spinal pain problems. It can reduce the movements due to muscular imbalances, decreased activity of daily living, and effects on health-related quality of life. It is the major cause of activity limitation, work absence, and reported clinical issues. Most of the cases of low back pain remained undiagnosed and received only symptomatic management.

Read the detailed description

There is limited literature on advanced soft tissue release techniques provided by primary healthcare practitioners specific to low back pain. Some of the studies are based on soft tissue mobilization using a mechanically assisted method, but they have limited outcomes, acute effects, and small sample sizes, which limit their generalization. Further literature is limited in the comparison of IASTM and SASTM. Further, there are limited techniques that can facilitate practitioners to identify the restrictions.

Firstly, instrument-assisted soft tissue mobilization (IASTM), due to its body contour and shape, recognizes specific tissue lesions and restriction sites while targeting specific points rather than using manual methods that cover a larger contact area. Using the mechanotransduction phenomenon, its mechanical stimuli initiate biochemical signals that trigger cellular responses and ultimately functional improvement. Biomechanically, fascial elasticity, fascial stiffness, and viscosity absorb and distribute forces. While tissue hydration level is increased, that is compromised in chronic low back pain.

Secondly, sound-assisted soft tissue mobilization could be an intervention for treating musculoskeletal disorders. The SASTM technique has the potential to be a game-changer in pain management after IASTM. The sound decreases as adhesions are broken. While breakdown of scar tissue can be a facilitator for ease of movement patterns.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SASTMDevice

    The therapist will apply sound instrument-assisted soft tissue mobilization (SASTM) with a convex plastic (Ceramic) tool (Beer JA, 2019).

  • IASTMDevice

    The IASTM technique contains a protocol for treatment that contains five components: i. Examination, ii. warm-up exercises 5 min iii. IASTM treatment (e.g., 30-60 seconds per session), iv. Post treatment stretching and strengthening, v. Icing (only when sub-acute inflammation is of concern).

  • ExerciseOther

    In conventional therapy, patients will be given an exercise program that will be targeted to low back muscles. This will be include three type of exercise focusing on stretching, strengthening and postural correction exercise.(Yana et al., 2024)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain Intensity

    The pain will be assessed using Chronic Pain grading Scale (CPGS).

    Measured: Pain intensity will be noted at baseline ,after the 2nd week, 3rd week, 4th week, and follow up will be taken at 2nd month, and after the 4th month post intervention.

  2. Flexibility

    Modified-Modified Schober Test will be used to measure Lumbar flexibility.

    Measured: The lumbar flexibility will be noted at basline after the 2nd week, 3rd week, 4th week, and follow up will be taken at 2nd month, and after the 4th month post intervention.

Secondary outcomes (3)
  1. Function

    Functional movement Screen (FMS) will be used.

    Measured: The functional movement screening will be noted at baseline, after the 2nd week, 3rd week, 4th week, and follow up will be taken at 2nd month, and after the 4th month post intervention.

  2. Disability

    Roland Morris Disability Index will be used to measure disability Index.

    Measured: Disability will be assessed before treatment, after the 2nd month, and 4th month post-intervention.

  3. Hamstring Flexibility

    Active knee Extension Test will be used to assess hamstring Flexibility.

    Measured: Hamstring flexibility will be measured at basline, 2nd month, and after the 4th month post intervention.
