Correlation Study between Non-Specific Low Back Pain and Back Extensor Endurance in Peons

Background and Purpose: In India 60% of the suffering from low back pain are engaged in physically demanding and prolonged standing jobs out of which only 15% have specific diagnosis. Peons are important part of office, college labour work with average standing time for a college peon is 4-8hours which make them prone to lower trunk extensor endurance. Thus the aim of the study is to find the co-relation between back extensor endurance and non specific low back pain. Methods: A study of total 30 participants was carried out amongst randomly selected peons working in college, after fulfillment of inclusion and exclusion criteria. NPRS (Numerical Pain Rating Scale) was used to asses pain and Biering-Sorenson test was used to asses muscle endurance of back extensors. Result: Most prevalent that is, 60% of the participants have moderate intensity of pain, that is more than half of samples taken.23% suffer from severe intensity pain and 17% suffer mild pain.33% of the population has hold time 31-60 sec.27% of the population has 91 to 120 sec and 20% have 61-90 sec 13% have 0-30 sec and 7% have hold time between 120 to 150 sec. The participants having with least pain has highest holding time and participant having pain more than 6 have the least hold time.
