The physiotherapist used the regression techniques for 1 hour of session 2 times for 8 weeks. The caudal component involved the spinous process of the treated segment touching the therapist's hand and not applying force as though mobilising the segment at grade 2. These were applied if there is a suspected case of a posterolateral disc prolapse where the aim is to increase the diameter of the foramen and decrease the tension exerted on the nerve root. Applied posteroanterior was used to distract the anterior intervertebral end plate and to approximate the posterior end plates so as to pull back the protruded nuclear material by creating a negative pressure.

The Roland-Morris low back pain and disability questionnaire (RMD) was utilised to evaluate the quality of life prior to and following the completion of the treatment. This questionnaire has demonstrated strong validity and reliability. The score is measured on a scale of 0 to 24, and percentage scores were calculated for each participant. Greater scores indicate a greater level of disabilities. Its sensitivity is 95%, and its specificity is 69%.

The normal angle for an SLR is from 0-35 degrees, which signifies the least amount of strain. Stretched from 35-70 degrees, sciatic nerve root stretching is achieved, and possible problems such as herniated disc or radiculopathy may be evidenced. 70- 90 degrees reflect highest normal flexibility: it may be related to hip joint pathology or some other conditions which are not a result of nerve injury. During both the first evaluation and the final therapy, the SLR was assessed using a digital inclinometer (clinometer) installed on a Techno Camon 20 Android phone. The digital inclinometer has been found to exhibit high levels of reliability and validity
