Core Stability Exercises With Surface Electromyography Biofeedback in Patients With Mechanical Low Back Pain
Study Details
Study Description
Brief Summary
This study will be conducted on patients of mechanical low back pain. Surface electromyography biofeedback driven core stability protocol will be given to experimental group and the control group will be treated with core stabilization regimen. Then it will compare the effects of surface electromyography biofeedback with core stability on postural stability and sensory integration of balance .

Detailed Description
Low back pain is very common musculoskeletal condition involving lumbar spine .it is almost affecting 80 % of world's population. Mostly it is self-limiting but it is episodic in nature.it is not an isolated problem it is usually associated with social occupational stresses and psychological issues.it is significantly associated with severe disruption in functional disability morbidity. Postural control involves information processing from sensory stimuli derived from the visual, vestibular and somatosensorial systems in an integrated way to accurately regulate body positioning and center of mass movements. If one or more of these systems fail, or the sensory information is not correctly processed, the risk of a fall or instability increases. LBP can alter the sensory input to postural control ,hence leads towards lumbar instability due to weakness of core muscles in chronic low back pain it will leads to hypermobility of lumbar spine which will further adds to deterioration of internal homeostasis and motor control of lumbar spine. SEMG biofeedback can be used to help "down-train" elevated muscle activity or to "up-train" weak, inhibited, or paretic muscles.
This study will be Single blind Parallel group randomized controlled trial. The study settings will be Riphah College of Rehabilitation And Allied Health Sciences Lahore, Department of Physical Medicine and Rehabilitation Sciences, Fauji foundation Hospital Rawalpindi and Foundation University Institute of Rehabilitation Sciences. On Probability Purposive Sampling Technique will be used for sampling .A sample of 52 patients of mechanical low back pain will be obtained by using online sample calculator clincalc.com. Subjects will be randomized in to two groups i.e. Control group includes core stability exercises. Experimental group core stability with sEMG biofeedback using sealed envelope method with 1:1. In current study the assessor will be blinded from treatment allocation. The study participants satisfying the inclusion and exclusion criteria will be recruited in this trial after informed consent. Baseline assessment will be done on all participants by a Physical therapist Patients will be randomly allocated to control group (n=26), and interventional groups (n=26).Treatment will be given 3 times a week by researcher for 6 weeks with a total of 18 sessions for each patient .Re-assessment will then be done after 2nd week 4th week and at termination of treatment after 6th week

Outcome Measures
Primary Outcome Measures
- Postural Stability [6 weeks]
it will be measured by using postural stability Balance System (R=0.94) (WJC Cachupe et al, 2001). This test is performed with open eyes as well as eyes closed and overall stability index will be calculated at the end of the test along with the percentage of time spent in each of the quadrants and zones (A to D).This test also provided information about the anterior /posterior index and Medial/Lateral index of participation
Secondary Outcome Measures
- Sensory integration of Balance [6 weeks]
The Clinical Test of Sensory Interaction and Balance CTSIB is an accepted test protocol for sensory component of Balance assessment on a static surface. The CTSIB test protocol was selected for Fall Risk assessment as it is well documented in the literature as an effective test in identifying individuals with mild to severe balance problems Clinical test of Sensory Integration of Balance (CTSIB) using 4 different conditions using balance Balance System (R=0.94) (WJC Cachupe et al, 2001) Eyes open firm surface: Baseline: Incorporates visual, vestibular and somatosensory inputs Eyes closed firm surface: Eliminate visual input to evaluate vestibular and somatosensory inputs. Eyes open on a dynamic surface used to evaluate somatosensory interaction with visually input Eyes closed on dynamic surface: used to evaluate somatosensory interaction with vestibular input
- Low Back Pain [6 weeks]
Numerical pain rating scale is a patient self-report scale for measurement of pain intensity in the clinical and research settings. The NPRS has reliability from 0.67-0.96 patient rate his pain on the scale of 0-10: 0 - (no pain) and 10 - (worst pain).
- Low back related functional disability [6 weeks]
The Roland-Morris Disability Questionnaire is designed to assess self-rated physical disability caused by low back pain. The Roland-Morris Disability Questionnaire is most sensitive for patients with mild to moderate disability due to acute, sub-acute or chronic low back pain. (R= 0.42 - 0.91) Macedo et al. (2011)
- Lumbar Range of Motion [6 weeks]
Lumbar Physiological movements including forward bending, backward bending, and Right & Left side bending measured via Bubble Inclinometer. Inter-rater and intra-rater reliability for the inclinometer with Intra-class Correlation Coefficients of 0.90 and 0.85 for lumbar
