The goal of this randomized clinical trial is to learn if the given interventions that is jandas approach versus Proprioceptive Neuromuscular Facilitation technique can treat pain, disability, range of motion, endurance and quality of life in patients with Lower cross syndrome on both genders and age group of 25-40 years. The main questions it aims to answer are:

Does jandas approach versus Proprioceptive neuromuscular facilitation technique improves pain, disability, range of motion, endurance and quality of life in patients with lower cross syndrome?

There is a comparison between two groups: Researchers will compare the jandas approach and proprioceptive neuromuscular facilitation technique to see if there is effects on pain, disability, range of motion, endurance and quality of life in patients with lower cross syndrome.

Participants in group A will be given

• Heating pad for 10 minutes
• Core stability exercises for 20 minutes with 10 seconds of rest intervals
• Proprioceptive Neuromuscular Facilitation technique was used for stretching of erector spinae, quadratus lumborum, rectus femoris and iliopsoas and rhythmic stabilization technique for strengthening. Stretching was performed using contract-relax technique in supine, prone and side lying positions. The Contract-Relax method included the target muscle to be lengthened and held in lengthened position while the patient contracted the Target-Muscle to its maximum position isometrically 3 to 6 seconds.
• Rhythmic stabilization technique was used to strengthen and stabilize the postural trunk muscles of hip: Abdominals and gluteal muscles strengthening and Participants in group B will be given
• Heating pad for 10 minutes
• Core stability exercises for another 20 minutes.
• After which it was treated with the Janda's approach of musculoskeletal pain that includes strengthening of the weakened muscles and stretching of the tightened muscles including Stretching exercise for erector spinae and back extensors muscles Stretching exercises for iliopsoas muscle and rectus femoris muscle Strengthening exercise for abdominal muscle and gluteal maximus muscle

A Randomized Clinical Trial was conducted at Riphah Clinic Lahore. A total of 52 patients (N=52) were assessed for eligibility criteria through non-probability consecutive sampling technique. 6 participants were excluded from the research. These 6 patients rejected to be the part of the study and declined any treatment. Hence 46 participants were included in the study that were first assessed and diagnosed with lower cross syndrome and met the inclusion criteria. As a result, total of 46 patients including (females: 39, males: 7) were considered eligible for the study. They were randomized through computer generated software. The list was concealed by a sealed envelope. The group A was labeled as 1 and group B was labeled as 2. Patients enrolled in this study have age between 25-40 years. Consent form was filled before the start of the treatment. The participants were randomly enrolled into two groups named as group A and group B. Baseline assessment of pain, disability, quality of life, lumbar range of motion, hip range of motion and endurance was taken using NPRS, ODI, SF-36, inclinometer, goniometer and McGill test of endurance respectively, before the start of the treatment by an assessor. Both groups: A and B received baseline treatment that consisted of a heating pad for 10 minutes followed by core stability exercises for 20 minutes with 10 seconds of rest intervals. Patients were advised to stretch for 5 minutes then perform lumber stability exercises.

Group A The group A first received the baseline treatment mentioned above then Proprioceptive Neuromuscular Facilitation technique for stretching and rhythmic stabilization technique for strengthening. PNF stretching was performed using contract-relax technique in supine, prone and side lying positions. The Contract-Relax method includes the target muscle to be lengthened and held in lengthened position while the patient will contract the Target-Muscle to its maximum position isometrically for an allotted amount of time that varies from 3 to 6 seconds. The muscle which is contracting is the agonist and the muscle which is relaxing is called the antagonist.

• Erector spinae stretching: Ask the patient to lie down and bring both the legs up to their chest by grabbing around their knees to stretch erector spinae muscle. Ask the patient to tuck in their chin and hold the stretch for 6 seconds of contraction with 80% force of the maximal isometric contraction on the erector spinae followed by a 15-second passive static stretching in the opposite direction of the muscle.

Quadratus lumborum stretching: the patient will perform active lateral flexion of the spine. To stretch the right QL the patient will laterally flex the spine to the left and vice versa. Ask the patient to hold the lateral flexion for 6 seconds of contraction with 80% force on the of the maximal isometric contraction on the muscle followed by a 15-second passive static stretching in the opposite direction of the muscle.

Rectus femoris stretching: the patient will lie in a side lying position on the treatment couch. The patient will flex the uppermost testing knee backwards and the therapist will hold onto above the foot of the patient, bend the knee to 90 degree and will pull the hip into extension and will ask the patient to hold a 6 second contraction with 80% force of the maximal isometric contraction of muscle followed by a 15-second passive static stretching in the opposite direction of the muscle.

Iliopsoas stretching: by using the modified Thomas test position, the patient will lie supine on the treatment table. Ask the patient to hold the unaffected leg towards their chest, the therapist will then hold the leg to be stretched above the knee and will provide a constant force to stretch and extend the leg. The contractions will be held for 6 seconds with 80% force of the maximal isometric contraction of muscle followed by a 15-second passive static stretching in the opposite direction of the muscle Rhythmic stabilization technique; is also a PNF technique that is shown to strengthen and stabilize the postural trunk muscles of hip and shoulder girdle. Therefore it will be used for the strengthening of the abdominal muscles and the gluteal muscles.

• Abdominals and gluteal muscles strengthening: Ask the patient to lie on the mat with both the knees flexed. The patient will raise their hips and perform a glute hold for 2 to 5 seconds against the resistance applied by the therapist. Hip rolls can also be performed by the patient in each direction against the resistance applied by the therapist.

Group B: The group B received heating pad for 10 minutes and core stability exercises for another 20 minutes after which it was treated with the Janda's approach of musculoskeletal pain that includes strengthening of the weakened muscles and stretching of the tightened muscles. This approach included:

• Stretching exercise for erector spinae and back extensors muscles
• Stretching exercises for iliopsoas muscle and rectus femoris muscle
• Strengthening exercise for abdominal muscle and gluteal maximus muscle. Stretching exercise will be performed actively for 30 second hold and 3 repetitions.

Strengthening exercise will be performed for 10 second hold and 10 repetitions. All Exercise will be performed 3 times per week for total of 4 weeks

• Age group of 25-40 years.
• Both genders male and female.
• NPRS score range from 4-7.
• Modified Thomas test positive , Back extensor test positive, prone hip extension strength test positive , Trunk flexion strength test positive.

Exclusion Criteria:
