About this study
Official title: Effects of Sub-occipital Muscle Inhibition Technique on Hamstring Flexibility in Post-laminectomy Patients
to find out the effects of sub-occipital muscle inhibition technique in combination with upper cervical spine exercises on hamstring muscle flexibility in post-laminectomy patients.
Read the detailed description
Laminectomy is a decompression surgery which is performed to decrease pressure on spinal nerves. In this surgical procedure a small bone of vertebrae called lamina is removed. Hamstring muscle stiffness is a major problem in post-laminectomy patients, which results in chronic pain, functional limitation and affect patients activity of daily life.
In post-laminectomy patients hamstring stiffness is more profound than iliotibial Band and piriformis stiffness. Sub-occipital muscle and hamstring are connected via a single neural pathway called superior back line which passes through dura matter. Dura matter is the outer most covering of meninges, Sub Occipital Muscles attached to dura matter by Myodural Bridge through vertebral dural ligament. This connection provides a window for relaxation of dural fascia to decrease tone of connected muscular-skeletal units (in which hamstring is also included). So if any of these muscle units become tight, or tone deterioration occur the other unit is automatically malfunctioned. The study shows that if tone sub-occipital muscle falls, it has been reported that the tone of knee flexors such as hamstring also decreases due to relaxation of myofascia.
However, in post-laminectomy patients, incorporating a neural pathway connection technique involving sub-occipital muscle inhibition for upper neural pathway Dura release may offer more effective and immediate results on hamstring muscle flexibility in the lower neural pathway The sub-occipital muscle inhibition technique is a method of inducing relaxation of the fascia by applying soft pressure to the sub-occipital area.
The rationale of the present study is to find out the effectiveness of Sub Occipital Muscle inhibition technique for stiff hamstring muscle in post-laminectomy patients, pain and disability. To compare the effectiveness of SOM inhibition technique in combination of upper cervical spine muscle stretching,traction etc. with hamstring muscle stretching, lower limb neurodynamic etc.

What is being measured
The primary outcome is the main question the study is designed to answer.
Active knee extension test
Patient is supine, unaffected limb on support surface and the examined limb elevated so that hip in 90 degree of flexion and knee to extended position perpendicular to ground. A lag of 20 degrees is considered normal from full extension, less than 20 degrees is considered as hamstring muscle tightness
Measured: two weeks
Numeric pain rating scale
The NPRS is a self-reported, or clinician administered, measurement tool consisting of a numerical point scale with extreme anchors of 'no pain' to 'extreme pain'. The scale is typically set up on a horizontal or vertical line, ranges most commonly from 0-10 or 0-100, and can be administered in written or verbal form.
Measured: two weeks
Modified Oswestry disability index
The Oswestry Disability Index (aka the Oswestry Low Back Pain Disability Questionnaire) is an extremely important tool that researchers and disability evaluators use to measure a patient's permanent functional disability. There are 10 questions, for each question there is a possible 5 points; 0 for the first answer, 1 for the second answer, etc.
Measured: two weeks

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Feb 2025.
