Non-invasive Measurement of Thoracic Kyphosis and Lumber lordosis among Agricultural workers and Corporate Professionals( IT) using Flexicurve Ruler

Abstract

Background: This study was undertaken to introduce a non- invasive technique for clinical diagnosis of spinal cord deformities. The purpose of the present study is to evaluate the postural deformities and onset of thoracic Kyphosis and lumber Lordosis among agricultural workers and Information Technology workers.
 Methodology: This cross-sectional study was carried out on thirty Agricultural workers (41-45 years) and twenty-five Information Technology workers (21-25 years) and their age matched control groups. The subjects were taken from their respective population by simple random sampling method. Measurements were made by Flexicurve Ruler in special standing posture. Kyphosis and Lordosis angles and Indices were calculated.
 Results: It indicates that maximum percentage of subjects had kyphotic angle between 400 -600. Twenty-three out of 30 agricultural workers (76.66%) and 22 out of 25(88%) information technology workers had kyphosis angle between 400- 600 but the same in case of control groups were 60% and 64% respectively. Maximum subjects had lordotic angle between 300 - 500. Thirteen out of 30 agricultural workers (43.33%) and 17 out of 25 information technology workers (68%) had lordotic angle in between 300 -500.The same in case of control groups were 43.33% and 56% respectively. Kyphosis index, Kyphosis angle and lordosis index, lordosis angle are significantly lower (p<0.05) in agriculture workers in comparison to its control group but the differences are not significant in case of information technology workers as well as between agriculture group and information technology group. But information technology workers show higher values of Kyphosis and lordotic index than agriculture workers, probably due to prolong sitting posture at work. Again 47% agricultural workers and 11% IT workers reported lumbar pain when compared to control groups (10% and none respectively).
 Conclusion: Although no significant deviation of kyphotic and lordotic angle has been observed in agricultural and information technology workers but significantly higher percentage of these 2 groups reported shoulder and lumbar pain indicating risk of dysfunction in shoulder, pelvic girdle and spine. Thus measurement of thoracic kyphosis and lumbar lordosis may be useful in examining the degree of spinal cord deformities. By utilizing these information therapeutic and ergonomic intervention can be applied and application of modern sophisticated machine for improvement in postural condition can reduce their work stress and disabilities.

“…Tandai processus spinosus L1 dan L5 dengan pena stabilo yang bisa dicuci. 13 Selama pengukuran, responden tetap berdiri tegak lurus tanpa alas kaki, dengan lutut lurus, kaki paralel serta bahu dan siku ditekuk 90 derajat selama pengukuran. 13 Atau responden dapat berdiri tegak sesuai posisi anatomis semampu responden.…”

“…13 Selama pengukuran, responden tetap berdiri tegak lurus tanpa alas kaki, dengan lutut lurus, kaki paralel serta bahu dan siku ditekuk 90 derajat selama pengukuran. 13 Atau responden dapat berdiri tegak sesuai posisi anatomis semampu responden. 14 Bersihkan flexicurve menggunakan tisu basah dan pastikan kondisi instrumen dalam keadaan baik tanpa ada tonjolan.…”

“…Tandai segmen L1 dan L5 pada skala metric flexicurve. 13 Pastikan kurva lumbal dipertahankan dan tidak ada jarak antara kulit responden dengan instrumen. 15 Setelah mencetak kontur tulang belakang, lepas instrumen secara hati-hati dan sisi dalam flexicurve yang menempel dengan kulit di jiplak ke atas kertas menggambarkan kurva lumbal pada bidang sagital dengan prosesus spinosus yang telah teridentifikasi juga di tandai.…”

“…13,15 Hasil ukur akan diperlihatkan dalam bentuk tabel dan dihitung menggunakan rumus Lordosis Index (LI) yaitu [(LW/LL) x 100] dan rumus Lordosis Angle (θ) = 4 arc tan [(2 ×LW)/LL], dimana LL (Lordosis Length) merupakan garis lurus yang ditarik dari posisi L1 ke L5 sesuai dengan panjang lumbar lordosis dan LW (Lordosis Width) merupakan garis tegak lurus yang digambar dari titik tertinggi di kurva lumbal ke titik di mana garis tersebut memotong garis LL. 13 Penelitian ini dilaksanakan di Institut Seni Indonesia Denpasar Bali, mulai dari bulan Agustus sampai September 2021. Pengambilan data diri dilaksanakan secara online melalui kuesioner yang disebar dalam bentuk google form kepada responden.…”
