Modalities (TENS, US, and superficial heat) All participants received conventional TENS (Chattanooga, Intellect Advanced, USA) with the following parameters: frequency, 100 Hz; pulse duration, 60 ms; amplitude-modulated frequency, 10%; and intensity adjusted to a comfortable tingling sensation. Two electrodes (single channel) were used: the first was placed over the ipsilateral lumbar region, and the second over the popliteal fossa. The duration of the TENS was 20 minutes (Ozen et al., 2023). A ten-minute continuous Ultrasound (US) model (Chattanooga, Intellect Advanced, USA) was applied over the nerve roots. The 5 cm² US head was used, with a frequency of 1 MHz and an intensity of 1.5 W/cm² (Ozen et al., 2023). Exercises in the form of pelvic rocking From the supine position, the participant was asked to bend their hips and knees partially, then arch their lumbar spine, and finally press the bed with their low back. This exercise was performed 10 times per session.

The patient lies in a crook lying. Both hips are flexed to beyond 90° with knees bent. The therapist supports the pelvis/legs. The knees are brought to the side, limiting the SLR, while rotating the pelvis and trunk as far as possible without pain. The therapist was allowed to change the hip / lumbar position (flexion/extension) if pain is provoked. Sustain for 20 seconds and return to the start position painlessly. Reassess SLR in supine (Wayne Hing et al., 2020).
