Intervention / Comparator Agent  
Type  Name  Details 
Intervention  Abdominal Hollowing Exercise and Piriformis Stretching Exercise  The intervention involves abdominal hollowing and piriformis stretching exercises for patients with spondylolisthesis. The abdominal hollowing exercise aims to strengthen the deep abdominal muscles, particularly the transversus abdominis, which plays a key role in spinal stabilization. This exercise is performed in two positions: crook lying and standing, with the participant drawing the belly button inward without tilting the pelvis, holding for 5-10 seconds, and repeating 10 times. The piriformis stretching exercise targets the piriformis muscle to alleviate tightness and improve flexibility. It is performed by crossing one leg over the other and gently pulling the knee toward the opposite shoulder, holding for 10 seconds, and repeating 10 times. The exercises are done once a day, 3-4 times a week for six weeks. 
Comparator Agent  Standard Physiotherapy Treatment  The control group receives standard physiotherapy treatment, including general exercises for stretching, strengthening, and lumbar flexion. The treatment focuses on improving flexibility, reducing muscle tension, and strengthening core and lower back muscles to improve spinal stability. The control group also receives postural education, providing guidance on proper posture during sitting, standing, and walking to prevent further strain. The treatment is administered 3-4 times a week for six weeks. 
 
Inclusion Criteria  
Age From  18.00 Year(s)
Age To  60.00 Year(s)
Gender  Both 
Details  Participants eligible for the study must meet the following criteria:

Both male and female patients, regardless of age, diagnosed with spondylolisthesis through radiological examination of the lumbar spine (L1 to L5 segment).

Patients experiencing low back pain with or without leg pain, regardless of whether the condition is acute or chronic.

Patients with reduced functional capacity due to spondylolisthesis, as assessed by standard disability questionnaires.

Participants willing to provide informed consent and participate in the full course of the study. 
 
ExclusionCriteria 
Details  Participants will be excluded from the study if they meet any of the following criteria:

History of spinal surgery, especially those with spinal fixation, as they may not respond to physiotherapy.

Any prior exercise therapy for back pain in the last 2 months, as this may affect the response to the interventions.

Presence of any neurological disorders that could interfere with participation or the treatment outcomes.

Patients with conditions other than spondylolisthesis causing back pain.

Pregnant women, as certain exercises may be contraindicated during pregnancy.

Diagnosed with spinal tumors, tuberculosis, or other systemic diseases contraindicated for physiotherapy.

Severe psychological disorders that may hinder the patient’s ability to comply with the exercise regimen.

Lack of cooperation, motivation, or dissatisfaction with the treatment protocol.

Primary Outcome  
Outcome  TimePoints 
Pain Intensity: Measured using the Dallas Pain Questionnaire (DPQ) at baseline and post-intervention (6 weeks).

Functional Disability: Assessed with the Oswestry Disability Index (ODI) at baseline and post-intervention (6 weeks).

Kinesiophobia (Fear of Movement): Measured using the Tampa Scale for Kinesiophobia (TSK) at baseline and post-intervention (6 weeks). 
6 weeks of treatment (18 sessions). 
 
Secondary Outcome  
Outcome  TimePoints 
Improvement in Spinal Mobility: Measured by range of motion tests (not detailed in the thesis, but typically assessed during the intervention period).

Quality of Life: Measured through general health and well-being questionnaires, if applicable (not explicitly mentioned, but often included in such trials). 
6 weeks of treatment (18 sessions).

Brief Summary   This study aims to evaluate the effectiveness of abdominal hollowing and piriformis stretching exercises in managing symptoms of spondylolisthesis. The randomized controlled trial will involve 60 participants, who will be randomly assigned to either an experimental group receiving the exercises or a control group receiving standard physiotherapy treatment. The primary outcomes of the study include pain intensity, functional disability, and kinesiophobia. Data will be collected at baseline and after 6 weeks of intervention. The goal is to assess whether these exercises can significantly reduce pain, improve mobility, and decrease fear of movement in patients with spondylolisthesis.
