Background: Strength, muscular endurance and flexibility are important component of healthy back function. Lack of endurance of trunk muscles is an important factor in etiology of low back pain. Nurses have a multidi- mensional role. They need to acquire various positions which lead to undue stress over low back, neck and hands amongst which prevalence of low back pain is highest. Aims and Objectives: To test trunk muscle endurance using lumbar functional tests for Trunk extensors, Trunk flexors, Trunk lateral flexors (right), Trunk lateral flexors (left). Materials and Methods: A cross sectional study was conducted with a sample of 80 nurses between age of 20-30 years also Nurses practicing more than 2 years having BMI within 18.5 - 24.99 kg/m 2 and Nulliparous women were included in the study. Subjects with history of Recent spine injury or trauma, Spine fracture, Pathological LBP, Subjects having history of any cardiovascular or pulmonary disorder or neurological conditions, Diabetes mellitus and hypertension, Mechanical LBP, Recent Cervical or Shoulder pathology were excluded. All subjects were selected by convenient type of sampling, Modified Oswestry Low Back Pain Disability Questionnaire was given to all the subjects and the subjects with the low back pain were excluded. A trial demo was given to the subject as to make them understand what they have to perform. Subjects were asked to hold the position and the no. of seconds was recorded. This no. of seconds was compared with the normal trunk endurance data. Results: Trunk muscle endurance in Nurses was reduced then Normal published data. Conclusion : The study concluded that there is reduced trunk muscle endurance in female nurses when compared to published normative data. KEY WORDS: Trunk muscle endurance, Nurses, Lumbar functional test.

Core stability is the prod- uct of motor control and muscular capacity of the lumbo-pelvic-hip complex proposing that the stability of the pelvis and trunk is necessary for all movements of the extremity[2]. Strength, muscular endurance, and flexibility are impor- tant components of healthy back function[3]. The vertebral column or spine is a part of axial skeleton. It houses the spinal cord and it is composed of 33 vertebrae and 23 intervertebral discs. The spinal stability is a three legged stool consisting of three subsystem i.e. passive [inert structures, bones and ligaments], active [muscles] and neural control. If any one of the
