• Registration Number: NCT06613620
• Lead Sponsor: Foundation University Islamabad

Brief Summary

This study is a randomised control trial and the purpose of this study is to determine the additional effects of surface electromyographic biofeedback on post facilitation stretching and strengthening in lower crossed syndrome.

.

Detailed Description

Participants will be recruited into their respective groups using a coin toss method. Lower crossed syndrome will be assessed using the following tests:

Prone hip extension test Trunk flexion strength test Tightness in erector spinae Modified Thomas test

Arm && Interventions

Group	Intervention	Description
Post Facilitation Stretching and Strengthening	Standard Treatment	Group A will recieve standard treatment of post facilitation stretching and strengthening. Strengthening will be divided into following phases 1. Warm up phase: 2. Strengthening phase: 3. Cool down phase:
Visual and auditory biofeeback	Standard Treatment	Group B will receive surface EMG biofeedback(visual and auditary) in addition to standard treatment.
Visual and auditory biofeeback	Visual and auditory feedback on SEMG biofeedback unit	Group B will receive surface EMG biofeedback(visual and auditary) in addition to standard treatment.
Electrical stimulation along with visual and auditory feedback	Standard Treatment	Group C will receive 3 types of feedbacks (electrical, visual and auditory) in addition to standard treatment
Electrical stimulation along with visual and auditory feedback	Visual and auditory feedback on SEMG biofeedback unit	Group C will receive 3 types of feedbacks (electrical, visual and auditory) in addition to standard treatment
Electrical stimulation along with visual and auditory feedback	Electrical muscle stimulation	Group C will receive 3 types of feedbacks (electrical, visual and auditory) in addition to standard treatment

Primary Outcome Measures

Name	Time	Method
Lumber lordotic angle	4 weeks	It will be measured using a mobile application. One sensor will be placed at the T12-L1 and other at L5-S1 spinous processes. The two angles will be recorded and their sum will be considered as the lumber lordotic angle.
Joint position sense	4 weeks	One sensor will be placed at T12-L1 and the other placed at L5-S1 simultaneously. Patient will be asked to flex and then extend maximally; his end ranges will be recorded. Within the middle range, therapist will decide the targeted angle for individualized patient. Patient will be asked to memorize the target position for 5seconds. The absolute error will measure by subtracting the actual angle and the target angle.
pain intensity	4 weeks	It will be measured on a numeric pain rating scale in which the subjects select a number ranging from 0-10 according to their intensity of pain. '0' score indicates no pain while '10' indicates worst pain experienced.
Functional disability	4 Weeks	It will be measured using a Modified Oswestry lower back Disability Index. It is a 10item based questionnaire and each item is further divided into 6statements. The score of '0-4' indicated no disability while 35-50 indicate complete disability.
