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. .

Conditions

Lower Cross Syndrome

Outcome Measures

Primary Outcomes (4)

• Lumber lordotic angle

  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.

  4 weeks

• Joint position sense

  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.

  4 weeks

• pain intensity

  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.

  4 weeks

• Functional disability

  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.

  4 Weeks

Study Arms (3)

Post Facilitation Stretching and Strengthening

EXPERIMENTAL

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:

Other: Standard Treatment

Visual and auditory biofeeback

EXPERIMENTAL

Group B will receive surface EMG biofeedback(visual and auditary) in addition to standard treatment.

Other: Standard Treatment; Other: Visual and auditory feedback on SEMG biofeedback unit

Electrical stimulation along with visual and auditory feedback

EXPERIMENTAL

Group C will receive 3 types of feedbacks (electrical, visual and auditory) in addition to standard treatment

Other: Standard Treatment; Other: Visual and auditory feedback on SEMG biofeedback unit; Other: Electrical muscle stimulation

Interventions

Standard Treatment OTHER

All participants will receive 4 weeks of intervention with a frequency of 3 times/week i.e. 10minutes of hot pack followed by post facilitation stretching and strengthening protocol. The exercise protocol will be taught to the patient by an experienced physiotherapist and supervised on the subsequent sessions. The protocol will be gradually progressed as per the patient's tolerance.

Electrical stimulation along with visual and auditory feedback; Post Facilitation Stretching and Strengthening; Visual and auditory biofeeback

Visual and auditory feedback on SEMG biofeedback unit OTHER

Patients will receive SEMG biofeedback assisted post facilitation stretching and strengthening. Patients will receive 50-80%of their maximum voluntary contraction as per the biofeedback and gradually the contraction time will be increased.

Electrical stimulation along with visual and auditory feedback; Visual and auditory biofeeback

Electrical muscle stimulation OTHER

Electrical muscle stimulation will be provided in addition to visual and auditory feedback by the SEMG biofeedback unit to the weak muscles until the patients achieve the desired level of contractions.
