Co morbidities of Myofascial Neck Pain among Information Technology Professionals: Mathankumar Mohandoss, Deepak Sharan, Rameshkumar Ranganathan, Jeena Jose; Ann Occup Environ Med 2014;26:21-21. Published online September 3, 2014; DOI: https://doi.org/10.1186/s40557-014-0021-4

Objectives

The objective of this study was to identify the musculoskeletal co-morbidities of neck pain of myofascial origin among IT professionals.

Methods

A retrospective report analysis of 5357 IT professionals from various IT companies in India was conducted. Demographic details, type and intensity of the musculoskeletal problems, employee feedbacks on status of musculoskeletal health and physician’s diagnosis were analysed. Descriptive statistics were used to describe the age, gender, body area affected and nature of work. Chi square test was used to find the association between musculoskeletal co-morbidities and myofascial neck pain (MNP).

Results

The study participants were predominantly males (71%). 41% of the population used laptops, 35% desktops and 24% both. Neck pain was the commonest reported symptom, followed by low back, shoulder and arm pain respectively. Statistical analysis also revealed that low back pain and shoulder pain, had a significant association with neck pain. Further analysis revealed that there was a significant association between the presence of MNP and thoracic outlet syndrome (p < 0.001) and fibromyalgia syndrome (p < 0.001). Other than the listed co-morbidities, eye strain was also found to be associated with MNP.

Conclusions

Low back pain and shoulder pain was found to be co morbid symptoms noted among IT professionals with MNP. Thoracic outlet syndrome and fibromyalgia were found to be the most commonly associated disorders with MNP among IT professionals.

Objective

The use of hand held devices (HHD) such as mobile phones, game controls, tablets, portable media players and personal digital assistants have increased dramatically in past decade. While sending a text message or using the controls of the HHD the users need to use their thumb and other palm muscles extensively. The objective of this study was to describe the risk factors and clinical features of the musculoskeletal disorders (MSDs) arising due to usage of hand held devices and to evaluate the effectiveness of a sequenced rehabilitation protocol.

Methods

A retrospective report analysis of 70 subjects, who were diagnosed to have a MSD affecting the upper extremities, was conducted. Medical charts from a tertiary level rehabilitation centre from 2005–2013 were analysed. All the subjects reported pain in their upper extremities following extensive usage of HHD and were examined and diagnosed to have a MSD by an orthopaedic and rehabilitation physician. After the assessment and diagnosis, all the patients underwent rehabilitation using a sequenced protocol.

Results

All the subjects reported pain in the thumb and forearm with associated burning, numbness and tingling around the thenar aspect of the hand, and stiffness of wrist and hand. 43 subjects had symptoms on the right side; 9 on left and 18 had bilateral symptoms. Correlation was found between hand dominance and MSD. 33 subjects complained of onset of symptoms following extensive text messaging. All the subjects were diagnosed to have tendinosis of Extensor Pollicis Longus and Myofascial Pain Syndrome affecting the 1st interossei, thenar group of muscles and Extensor Digitorum Communis. 23 of the subjects were senior executives, among these 7 were CEO’s of major multinational companies in India. All the subjects recovered completely following the rehabilitation.

Conclusions

The study concluded that mobile phones and gadgets that promoted the predominant usage of thumb or only one finger while texting or using the controls were associated with a higher prevalence of MSDs. Treatment using a sequenced rehabilitation protocol was found to be effective.

The Effect of a Stretching Exercise on Myofascial Pain Syndrome Patients in Small and Medium Sized Industries: Jung Wook Lim, Young Jun Kwon, Tae Won Jang, Jong Heon Lee, In Seok Kim, Sang Cheol Ryu, Jae Hoon Roh, Jong Uk Won, Bong Suk Cha, Chul Ho Lee; Korean Journal of Occupational and Environmental Medicine 2010;22(4):307-315. Published online December 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.4.307

Abstract PDF

OBJECTIVES
This study was conducted to identify the effect of a stretching exercise on myofascial pain syndrome patients that work in small and medium-sized industry.
METHODS
Questionnaires surveys including general characteristics, work-related characteristics, and musculoskeletal symptoms on neck and shoulder area was administered to 393 subjects who worked in small and medium sized industries. Symptomatic workers were examined to identify whether they had myofascial pain syndrome (MPS). Of the 393 subjects, 108 MPS patients performed 6 weeks stretching exercise program. Intensity of pain was estimated with visual analogue scales (VAS). All patients were interviewed to estimate their compliance to stretching exercise program.
RESULTS
Of the 393 workers, 119 workers were diagnosed with MPS of the neck and shoulder. Post-exercise VAS was significantly reduced compared to pre-exercise VAS (p<0.05). High compliance patients to stretching exercise were more effective to exercise therapy (OR 2.89, 95% CI 1.19~7.04), and overtime workers were less effective to exercise therapy (OR 0.41, 95% CI 0.17~0.95).
CONCLUSION
The Stretching exercise program was identified to be effective in MPS patients in small and medium-sized industries. It is recommended that workers with MPS in small and medium-sized industries practice a well-designed stretching exercise program, and avoid overtime work.

Analysis of Shoulder Range of Motion in Shoulder Myofascial Pain Syndrome: Jeong Soo Kim, In Ah Kim, Soo Jin Lee, Yong Kyu Kim, Si Bog Park, Jae Woo Koh, Jaechul Song; Korean Journal of Occupational and Environmental Medicine 2005;17(4):333-342. Published online December 31, 2005; DOI: https://doi.org/10.35371/kjoem.2005.17.4.333

Abstract PDF: OBJECTIVE: This study was carried out to investigate if the measurement of range of motion(ROM) could be applied in the diagnosis of Myofascial Pain Syndrome(MPS) and to determine the severity by analyzing ROM in MPS patients.
METHODS
The study subjects were 476 female telephone number information service workers. Southampton Protocol and Pittsburgh Protocol were used to diagnose MPS and to measure ROM. ROMs were measured by 2 inclinometers exercising each shoulder passively and actively in 5 directions ; abduction, forward flexion, extension, external rotation, and internal rotation.
RESULTS
Compared to the normal group (n=147), the mean of right side ROM in the subjects (n=270) with same side MPS was 2.1 degrees(SD=11.5) lesser in active extension and 1.7 degrees(SD=10.4) lesser in passive extension. Compared to the mild group (n=210), the mean of right side ROM in the patients with same side severe MPS (n=58) was lesser in all directions. Especially in active forward flexion, passive forward flexion, active extension, passive extension and active external rotation, ROM in the subjects with severe MPS was lesser by 6.5 degrees(SD=13.1), 5.1 degrees(SD=12.8), 5.9 degrees(SD=11.8), 5.0 degrees(SD=10.6) and 3.9 degrees(SD=9.8), respectively, than those of the subjects with mild MPS. Compared to the subjects with left side mild MPS(n=172), ROM in the subjects with left side severe MPS (n=59) was 5.3 degrees(SD=13.3) lesser in active forward flexion.
CONCLUSIONS
In this study, ROMs in the subjects with severe MPS tended to be lesser than those in mild patients. This tendency was more prominent in the right side than the left, active range of motion than passive and forward flexion and extension than others. The results of this study are expected to help diagnose shoulder MPS and determine severity.

The Effect of VDT Work on Work-related Musculoskeletal Disorder: Dorn Q Kim, Soo Hun Cho, Tai Ryoon Han, Ho Jang Kwon, Mina Ha, Nam Jong Paik; Korean Journal of Occupational and Environmental Medicine 1998;10(4):524-533. Published online December 31, 1998; DOI: https://doi.org/10.35371/kjoem.1998.10.4.524

Abstract PDF

As use of the visual display terminal (VDT) is becoming more generalized as a result of office automation, the so-called 'VDT syndrome' which is often observed with the workers using VDT has emerged as a serious occupational health problem. However, few comparative study with control group using not only subjective symptom but also physical examination hag been conducted. We have conducted a study comparing prevalence rates of musculoskeletal disorder between 113 VDT operators of a telecommunication company and the control groups of housewives and office ladies through a review of subjective symptoms as well as physical examination by physiatrist to understand the magnitude of problem and relative risk of VDT worker. The symptom rates of upper extremity disability in VDT operators were higher than those of controls especially in neck and shoulder area. Fifty-four(47.8%) of 113 VDT operators met our case definition of upper extremity disorder by subjective symptom and physical examination. Myofascial pain syndrome of neck and shoulder muscles were the most common(46.9%). The odd ratio of using VDT operation for developing myofascial pain syndrome in the neck or shoulder area were 2.52(compared to controls of office ladies) and 2.64 (compared to controls of housewives). Other anatomical lesion such as elbow, hand and wrist shows slight higher prevalence rates of musculoskeletal disorder than control groups but not statistically significant.
