Abstract

Background: It is seen that information technology (IT) professionals are at higher risk of developing mechanical low back pain due to numerous factors such as a sedentary lifestyle, attaining inappropriate posture for a prolonged period of time, work stresses, and inadequate exercise which lead to overload on the back musculature. Working from home has become the new normal for these professionals in which they attain abnormal posture which leads to pressure on the muscles and thus there is a need to estimate and analyze spinal muscle performance among IT professionals.

Materials and methods: Our main objectives were to estimate the spinal muscle performance in work-from-home IT professionals of Karad and to find the association between spinal muscle performance with respect to age, gender, and body mass index (BMI). Depending on inclusion and exclusion criteria, 120 IT professionals working from home were selected for this study by simple random sampling. Written consent was taken and a detailed outcome assessment was done by using the static and dynamic abdominal test, extensor test, internal/external oblique test, and back rotators test. Also, functional performance was measured using the back performance scale. SPSS version 20 was used to carry out the analysis of data and results were obtained.

Results: In participants of sample size 120 (100%), 27 (26%) were normal, 30 (32%) good, 24 (20%) fair, 21 (14%) poor, 18 (8%) trace; whereas, static extensor strength was 16 (12%) normal, 9 (18%) good, 24 (28%) fair, 18 (36%) poor, 3 (6%) trace. For oblique's, static strength was 10 (20%) normal, 12 (24%) good, 15 (30%) fair, 9 (18%) poor, 4 (8%) trace; whereas, for back rotators strength was 10 (20%) normal, 17 (34%) good, 15 (30%) fair, 8 (16%) poor. The mean number of repetitions for the dynamic endurance test for extensors was 11, for abdominals wase 24 and for obliques was 12. A back performance scale was found with a minimum score of 6 and a maximum score of 11 for activity limitation. There was statistically significant found to be between spinal muscle performance and age (P = 0.041), BMI (P = 0.027).

Conclusion: In this study it was found that spinal muscle performance was decreased in IT professionals. It was concluded that there was a significant reduction in static extensor performance compared to static abdominal muscle performance. Also, the spinal muscle performance of extensors was less as compared to that of abdominals. The data also revealed that there was a remarkable association that was seen between spinal muscle performance and age as well as spinal performance and BMI.
