Prevalence of Musculoskeletal Pain and Postural Deformity in Papad Making Women —A Cross-Sectional Observational Study
ABSTRACT
Aim and Objective: To study musculoskeletal problems like musculoskeletal pain, postural deformity and nerve radiculopathy in women engaged in Papad making by clinical assessment. Methodology: A cross-sectional observational survey carried out at Shri. Mahila Gruh Udyog Lijjat Papad, Nandanvan, Nagpur (2014). 50 female subjects were selected for the study. After taking permission from factory in-charge, the survey was conducted at the factory site and subjects were explained about the study in details in language they can understand. Consent form was obtained by subjects to participate. Data were collected by interview and clinical examination of women engaged in this occupation, As per proforma of musculoskeletal examination. Result: Almost 37 subjects out of 50 complaints about low back pain as a chief complaint followed by neck pain in 34, thoracic kyphosis was more profound postural deviation seen in 10 subjects. Paraspinal and calf muscle spasm is more common. Radiating pain and numbness more in dominant hand suggestive of involvement of median nerve were confirmed by Upper Limb Traction Test [ULTT]. Discussion: Socioeconomic status greatly influences the working needs of women. Shri. Mahila Gruh Udyog Lijjat Papad factory provides a platform for Women Empowerment. Faulty posture adoption for longer duration during work gives rise to various musculoskeletal problems. Conclusion: 74% of the study population has low back pain as a chief musculoskeletal problem. 34% present with postural deviation and 82% belong to poor socioeconomic scale.

1. Introduction

In developing countries, great efforts are directed towards the development of small industries as the engine for their economic growth. According to WHO, over 1000 million people worldwide are employed in small scale industries [1].

The “Papad Making Industry of India” is one such industry which has provided ample opportunity of employment for the women of lower socio-economic class. “Shri Mahila Gruh Udyog Lijjat Papad” is one of the oldest Papad making industries of India, women working in this small scale industries are from lower socio-economic class and preferred to work from home. Though such industries are identified with women empowerment in India [2] [3] [4] [5] , the employees are found to have not subjected to occupational health and safety provision. As a result, they suffer from various health problems [1] [5].

The women engaged in “Papad Making” industry prepared the “Papad” and delivered it to the company for further packaging and distribution through dealers. No machinery was used at the production level and everything was done manually from rolling of Papad at home to packing in the factory. While rolling Papad on Chakla, they used to sit on the ground with folding leg at their knee and hip and continuous forward bending posture for rolling Papad. In this posture, they sit for several minutes to hours, which causes increased strain on their back and Thoraco-lumbar region as reported by working women in that industry (see Figure 1) [5]. As explained by working women about their procedure of preparation, they need extra effort to roll Papad than normal Roti making, because dough to make Papad was comparatively hard and need more upper extremity strength along with back muscle. This faulty adaptive posture leads to protective spasm over Trapezius, Biceps, Hamstring and Calf muscle. Due to spasm, mobility was hampered and cause muscle imbalance [6] [7]. According to the explanation of Janda and his colleague, muscle imbalance resulting in upper crossed syndrome and lower crossed syndrome can be seen in this working women [5] [6] [8] [9].

These women were presents with tight Trapezius, Pectoral’s, Hamstring and Gastronomies. This muscle imbalance led to postural deformity like exaggerated thoracic kyphosis, reduced lumbar lordosis and scoliosis due to derangement and rotation of spinal vertebrae [8]. Repetitive strain over back and upper cervical due to faulty posture caused nerve compression. The epidemiological cross-sectional study by Chen et al. concluded that there was a significant association between seat inclination and the use of lumbar support with low back pain [10] [11]. There are various studies available to show that sitting without lumbar support and bending posture increases Disc pressure and electromyography activities of back muscles [4] [10] , so do the body parts involved in women working in Papad Making industry [12]. Hence the aim of this study is to check for the prevalence of various musculoskeletal problems in Papad-Making women.

The informal sector and small-scale industries in particular, are subjected to numerous workplace hazards [7] [13] and health hazards. These women require attention and modification in their traditional way of the method of preparation, as this ignorance can cause many musculoskeletal problems and pain. This ultimately results in deterioration in health and working capacities [12] [13]. In order to identify the occupational health hazards in the population of “Papad” Making women, this study was carried out. In this study, an attempt has been made to find out the musculoskeletal problem of the women engaged in “Papad Making” industry.

2. Methodology and Procedure

A Cross-sectional observational study was conducted on women working in one of the branches of the oldest Papad making industry in India named “Shri. Mahila Gruh Udyog Lijjat Papad”, Nandanvan, Nagpur (Oct 2014). After receiving permission letter from our institution, we planned a meeting to industry manager to make discussion about our study. We provided detailed explanation about our study and its importance, to seek permission to conduct this study on their workers at their workplace. After receiving permission letter, a survey was conducted. After providing detail information about study benefits, and written consent was obtained by all women ready to participate. A short interview questionnaire was assigned to all women for screening. Out of 110 women employers, only those women were included who involved in Papad rolling work with age group of 16 - 60 years, working for at least 6 months in this industry regularly and work for ≥5 hours a day. Women with neurological, cardiopulmonary and orthopedic conditions were excluded. Data were collected by interview questionnaire for inclusion in the study population. Total 50 women were selected for clinical examination after screening interviews. Kuppuswamy scale 2011 revised was used to score and grade the socioeconomic status (SES) of each participant [score 26 - 29 upper class, 16 - 25 upper middle, 11 - 15 lower middle, 5 - 10 upper lower, <5 lower]. Clinical examination was carried out to check for musculoskeletal problem as per proforma given in Annexure.

Pain was graded on Visual analogue scale of 10 [1—no pain, 5—moderate pain affecting activities, 10—extreme pain to tolerate]. Postural deviation was observed or assessed in standing position using plumb line as a reference of alignment for the body and deviations were noted accordingly as an exaggerated kyphosis or reduced or exaggerated lordosis. In posterior view, deviations of vertebral line with reference to plumb line were considered as scoliotic. Upper Limb and Lower Limb Traction Test was performed on participant sitting on chair and checked for tingling and numbness.

After collecting, Data were tabulated in different tables and respective graphs were obtained to show the impact of their occupation on their musculoskeletal system. Screening and clinical examination were carried out by a team of 4 physiotherapist in group

At the end of clinical examination, a brief session of ergonomic advice and exercise were educated by Physiotherapy professionals.

3. Result

Graph 1 showed the demographic data and socioeconomic status (Graded according to Kuppuswamy Scale 2011) and age of the working women and their economic statuses were arranged as Table 1. It showed that there was a maximum number [82% of total study population] of working women aged between 16 and 45 from poor socioeconomic status [86% of total study population].

Table 2 showed data arranged with respect to pain region involved in Papad making women result was obtained as, 74% of women are reported back pain as a chief complaint followed by 68% of women complaints pain in her neck. Other regions as shoulder, elbow, wrist, hip, knee and ankles were also involved to some extent.

Table 3 showed kyphosis was the most prevalent postural deformity in women involved in rolling Papad work, out of 50 women 10 showed mild to moderate kyphotic posture at thoracic level. 10 women presented with reduced normal lumber lordotic curvature and 2 women presented with mild scoliosis.

Table 4 showed that Median nerve radiculopathy was more common in women engaged in Papad rolling work, followed by femoral nerve and sciatic nerve involvement, though Radial, Ulnar and Peroneal nerve were not much affected.

4. Discussion

This cross sectional survey was an attempt to find out the musculoskeletal problems faced by women actually engaged in rolling Papad work. Hence, survey was conducted at “Shri Mahila Gruh Udyog Lijjat Papad, Nagpur”.

Musculoskeletal problems are the commonest health problem of the study population. Canadian women’s health network has reported that musculoskeletal disorders are the most serious hazard of working women [12]. Out of 50 subjects 37 subjects complaints more about low back pain [LBP]. The cause behind LBP was continuous sitting in forward bending posture increasing disc pressure in spine and electromyographic activity of back muscle as reported by as explained by Nachemson AL (1981) and Anderson BJ, Ortengren [4] [5] [10]. Neck was found to be the second most commonly affected region followed by the low back as complained by 34 women. The cause of neck pain was increased neck muscle tension by continuous physical exertion, postural muscle imbalance and tensing the muscles unconsciously in response to stress. The study done by How-Ran Guo on women working in industries reported that musculoskeletal disorder of body part other than the back was of the neck, shoulder, hands and wrist [4] [13].

During work, Subjects sat in forward inclination of 10˚ - 30˚, shoulders in 10˚ - 30˚ of abduction with forward flexion of 30˚ - 50˚ & elbow 10˚ - 20˚ of flexion and extension and slight wrist extension and sat on the floor while rolling Papad. During rolling activity, there was a repetitive strain on elbow and wrist flexors and extensors, as a consequence of which there was spasm, joint pain and restricted ranges of motion. Nerve is often get compressed due to repetitive movement of hands and nerves of lower limbs may get compressed due to lumbar plexus involvement because of increased disc pressure in lumbar region [4] [5] [10].

Also, 10 subjects showed mild to moderate Kyphosis and 5 subjects had Lordosis

While 2 subjects presented with Scoliosis. Dehghani et al. argued that subjects working with bending on the ground increased the percentage of kyphosis.

Neurological symptoms like peripheral radiculopathy were also there in complaint list of women assessed by upper and lower limb traction test, which revealed 14 subjects had median nerve stretch pain, 8 with femoral and 7 with sciatic pain. Bhrel et al. revealed that the repetitive strain of upper extremity resulted in median nerve compression [15] [16] [17] [18].

Socioeconomic status greatly influences the working needs of people. We found 41 people with Poor SES and 09 with Fair SES [5] [7]. In the “Papad Making” industry, there is no provision of retirement age, as the emphasis is on earning one’s bread through daily work, all through one’s life [1] [11]. Although such principle of this industry goes well with the self sufficiency of women, however it increases the duration of the occupational musculoskeletal problems.

5. Conclusion

This study concluded that, 74% of study population had Low back pain as a chief musculoskeletal complaint. 34% of study population presented with postural deviations. And almost 82% of study population was from poor socioeconomic status. Ignorance of women health led to many problems like absenteeism, low productivity and lack of quality product. Hence it is always needed to focus on their occupational health hazards on their musculoskeletal problems and improve their health status by providing quality treatment and awareness.
