Summary

This randomised controlled trial will evaluate the comparative effects of Maitland versus Mulligan spinal mobilization techniques, when combined with canal enlargement exercises, in patients with lumbar spinal stenosis (LSS). A total of 38 participants aged 25-40 years with confirmed unilateral LSS will be randomly assigned to receive either Maitland mobilizations or Mulligan mobilizations, along with standard physiotherapy and canal enlargement exercises. The intervention will be administered over three weeks, with four sessions per week. Primary outcomes will include pain intensity (measured by Numeric Pain Rating Scale), disability (Modified Oswestry Disability Index), and symptom severity (Swiss Spinal Stenosis Score), assessed at baseline and post-treatment. This study aims to inform physiotherapy practice by identifying the more effective manual therapy technique for improving functional outcomes in LSS.

Detailed description

This single-blinded, randomised controlled trial is designed to compare the effects of two manual therapy techniques, Maitland central posterior-anterior Grade III mobilizations and Mulligan spinal mobilizations (SNAGs), when combined with canal enlargement exercises and conventional physiotherapy. Thirty-eight participants with confirmed unilateral lumbar spinal stenosis will be recruited from the outpatient physiotherapy department at Allama Iqbal Memorial Teaching Hospital, Sialkot. Participants will be randomly assigned to one of two intervention groups using sealed opaque envelopes. Group A will receive Maitland mobilizations in addition to canal enlargement exercises and conventional physiotherapy, while Group B will receive Mulligan mobilizations along with the same exercise and conventional therapy protocol. The intervention will be administered four times per week over a period of three weeks (total of 12 sessions). The canal enlargement protocol includes bilateral knee-to-chest exercises, LION stretches, and cat-camel movements, all of which aim to increase lumbar flexion and spinal canal space. Conventional physiotherapy treatment will include the application of hot packs, transcutaneous electrical nerve stimulation (TENS), and stretching of the hamstrings and piriformis muscles. Primary outcomes will be assessed at baseline and after the 3-week intervention. These include: Pain intensity (Numeric Pain Rating Scale, NPRS) Functional disability (Modified Oswestry Disability Index, MODI) Symptom severity (Swiss Spinal Stenosis Score, SSSS) Data will be analysed using appropriate parametric and non-parametric statistical tests, based on data distribution. The findings of this study will provide insight into which mobilization technique is more effective in reducing pain and disability and improving function in patients with lumbar spinal stenosis. This may contribute to the development of more evidence-based physiotherapy protocols for LSS management.

Conditions

• Spinal Stenosis
• Low Back Pain

Interventions

Type	Name	Description
OTHER	Maitland Mobilization Group	Participants in this group will receive Maitland Grade III central posterior-anterior spinal mobilizations targeting the lumbar spine. The intervention will be administered by a licensed physiotherapist with the patient in a prone position, applying oscillatory mobilization for 3 sets of 40 seconds with 1-minute rest intervals. Canal enlargement exercises (bilateral knee-to-chest, LION stretch, cat-camel exercise) The total treatment will be administered four sessions per week for three weeks (12 sessions total).
OTHER	Mulligan Mobilization Group	Participants in this group will receive Mulligan spinal mobilizations with lower limb movement (SNAGs). The therapist will apply sustained passive glides to the lumbar spinous process while the patient actively elevates the leg in a pain-free range. Mobilizations will be performed in 3 sets of 7-10 repetitions. Canal enlargement exercises (bilateral knee-to-chest, LION stretch, cat-camel exercise) The total treatment will be administered four sessions per week for three weeks (12 sessions total).
