Trauma Disorders

Work sampling is proposed as a method for evaluating aggregate risks for cumulative trauma disorders in jobs. The approach assumes that an assessment of cumulative trauma disorder (CTD) risk factors within individual tasks has been made, and can be used in conjunction with the resulting estimates of proportion of time spent per task or activity to arrive at an overall estimation of CTD risk for the job. Important advantages of work sampling include that it estimates the availability of rest and recovery time within jobs, that the method can be applied to both cyclical and noncyclical jobs, and that small, practical samples may provide reasonable estimates in many cases. A case study utilizing work sampling in a workers compensation carpal tunnel syndrome (CTS) claims investigation using a single day sample interval is presented. Results suggest little or no CTD risk, a finding that was supported by historical evidence from a large population of workers (27,200) performing the same job. Only .0000025% of workers had reported a CTD over a period of 3 years. While support for causation of CTD was not found, the method identified a probability of aggravation of a possible pre-existing condition, which is also compensable. Details regarding the studied job are provided. The use of a work sampling method to assess CTD risks is discussed.

The first article reporting the rising incidence of carpal tunnel syndrome in histotechnologists was written by Pearl Gervais and published in the Louisiana Society for Histotechnology newsletter in 1991. Following that article, the growing interest in the number of injuries within the profession prompted a nationwide survey of histotechnologists. The results of that survey appeared in the first part of a three part article published in the Journal of Histotechnology, 18:139,1995. The articles were written by a group of professionals from the University of Michigan. Carpal Tunnel Syndrome (CTS) was used as the model for potential Cumulative Trauma Disorder (CTD).

Trauma Disorders

Chronic work injury will be implicated as a cause of upper extremity musculoskeletal disorders in increasing numbers of patients. A wide variety of conditions, some with a specific diagnosis (eg, carpal tunnel syndrome) and a known response to treatment in contrast to more generalized disorders (eg, tendonitis) where the prognosis is uncertain form part of the spectrum. Experience has demonstrated that as the diagnosis becomes less specific, job related and emotional factors can significantly affect the patient's presentation, response to treatment and timing to return to work. Care needs to be exercised in implicating work in the etiology. General terms such as ‘cumulative trauma disorder’ and ‘repetitive strain injury’ need to be avoided.

Ergonomi menjadi pilar kesehatan dan menjadi salah satu indikator kesejahteraan. perbaikan ergonomi perlu dilakukan sebagai salah satu upaya pencegahan terhadap penyakit CTDs (Cumulative Trauma Disorders) akibat faktor risiko kerja postur janggal, beban, frekuensi dan durasi yang bersumber dari pekerjaan, seperti nyeri tengkuk, nyeri pinggang bawah atau low back pain, rasa baal pada jari telunjuk, jari tengah dan jari manis yang disertai nyeri terbakar pada malam hari, kekakuan, lemah dan nyeri saat tangan digunakan dan dikenal dengan nama Carpal Tunnel Syndrome. Dalam ergonomi, postur tubuh adalah faktor yang sangat penting, salah satunya postur duduk yang setiap orang lakukan setiap hari dalam durasi berjam-jam. Tujuan utama membuat desain ergonomi untuk kursi atau tempat duduk dan meja adalah menciptakan sedemikian rupa bentuk kursi dan meja belajar, sehingga dapat mempertahankan postur tulang punggung yang fi siologis, dengan demikian diharapkan kerja otot tidak perlu berkontraksi secara berlebihan. Masalah ketidaksesuaian aspek ergonomi antara sarana kerja dan manusia serta pengaruhnya terhadap kesehatan belum mendapatkan perhatian yang serius di Indonesia. Hal ini terbukti dengan masih banyaknya tempat-tempat kerja yang belum berpedoman dengan kaidah ergonomi dalam hal penyediaan peralatan kerja bagi tenaga kerja. Ketepatan dimensi merupakan salah satu faktor penentu kenyamanan yang menunjang aspek fungsional dari suatu rancangan. Untuk menghasilkan suatu desain yang tepat dimensi perlu pertimbangan yang matang dan observasi yang cermat terkait dengan faktor manusia sebagai pengguna produk.

Surface Electromyograms

Cumulative Trauma Disorders (CTD) such as carpal tunnel syndrome, tenosynovitis, and strains are a common health problem among people who perform repetitive work with their hands. Repeated exertions and movements with certain hand postures, stresses on the surface of the hand and arm, vibrations, low temperatures, and use of gloves all have been identified as factors of CTD. To facilitate identification of these factors, a job analysis procedure based on traditional work measurement techniques was developed. Jobs are first divided into sequences of acts or elements; postures, forces, and other physical factors associated with each element then are determined. This process is facilitated by a video tape system that is used to film the job and can be played back in slow motion. A microcomputer is used to facilitate recording and storage of element sequences. Surface electromyograms of the medial forearm are calibrated and recorded on videotape for estimation of forces exerted with the hand. Finally, recommendations for control of CTD are based on identification of stressful elements.

The goal of this work was to improve productivity and prevent cumulative trauma disorders in manual work. Towards this end a design checklist was developed. The checklist contains twenty different questions with respect to physical factors that affect worker performance and stress—e.g., contact with sharp edges, vibration, size, and material of tool's handle etc. A score is given to indicate how well the factors on the list have been addressed. To provide immediate response to the user, the checklist was programmed and implemented on a personal computer (IBM PC). A pilot study was performed on seven jobs at one factory, using the computerized checklist. The analysis scores were correlated with the incidence rates of cumulative trauma disorders per 200,000 work hours in 1982 (r= −0.8678). These results support the feasibility of the use of a computerized checklist in job design. Future development of this system is discussed.

In the August 1995 issue (vol. 43, no. 8), in the article, “A Program Plan Addressing Carpal Tunnel Syndrome: The Utility of King's Goal Attainment Theory,” there was an error in the first entry of the references. The reference cites a report “Cumulative trauma disorders in the workplace: Costs, prevention, and progress,” indicating that is was published by the Government Printing Office. The publisher should be The Bureau of National Affairs, Inc. (BNA), a privately held publisher of print and electronic news and information in Washington, D.C.
