STATEMENT OF THE CASE
Wе are asked to decide whether carpal tunnel syndrome is an occupational disease as defined under the Indiana Occupational Diseases Act. Elsie Duvall appeals an award from the Worker's Compensation Board ("Board") in favor of her former employer, ICI Americas, Inc., which operates the Indiana Army Ammunition Plant in Charlеstown. The Board denied her claim for benefits, found that her work-related carpal tunnel syndrome did not constitute an occupational disease and found that as an injury, her claim was barred by the two-year statute of limitations for a claim under the Worker's Compensation Act. We affirm.
ISSUES
We restate the issues presented on appeal as follows:
1. Whether Duvall's carpal tunnel syndrome is an occupational disease under the Indiana Occupational Diseases Act or an injury under the Indiana Worker's Compensation Act.
2. Whether Duvall's claim is barred by the two-year statute of limitations.
FACTS
Duvall was employed from 1981 until September 28, 1987, on ICI's production line in a job described as "weigh, load and sew." By March of 1983, Duvall experienced the symptoms and was diagnosed with earpal tunnel syndrome. 1 Duvall then filed a worker's compensation claim and alleged that she suffered from a condition called "trigger thumb" of her right hand which was complicated by her carpal tunnel syndrome. The Board accepted the parties' stipulation that Duvall suffered no temporary total disability but found that Duvall's *1124 trigger thumb was caused by her employment at ICI without deciding the effect of her carpal tunnel syndrome. The Board awarded Duvall her medical expenses and attorney's fees. *
In September of 1984, Duvall again complained of pain and consulted Dr. Kasden who diagnosed a mild form of carpal tunnel syndrome in her right hand and wrist. Dr. Kasden prescribed a treatment regime of vitamins and night-splinting and placed restrictions on her work duties. Those restrictions precluded her from using vibratory tools, from heavy gripping or pinching with simultaneous flexing and extension of her right wrist, and from lifting more than five pounds. ICI honored Duvall's work restrictions until September of 1987 when it asked Duvall to perform work which exceeded the weight restriction prescribed by her physician. Duvall refused, and ICI then terminated her employment.
On September 18, 1991, Duvall filed an Application for Adjustment of Claim with the Board and alleged as grounds for her claim that "[rlepeated trauma to [her] hand caused carpal tunnel syndrome" to result from an initial job-related injury. Record at 9. Duvall sought "future medical bills ..., temporary total disability, and total disability." Record аt 9. Following an evidentiary hearing, the Board adopted the single Board member's findings and entered a decision which denied Duvall's claim. Duvall appealed that decision, and this court, in Duvall v. ICI Americas, Inc. (1992), Ind. App.,
DISCUSSION AND DECISION
Standard of Review
In this appeal from a decision of the full Worker's Compensation Board, we are bound by the Board's findings of fact and may only consider errors in the Board's conclusions of law. See IND. CODE § 22-8-4-8(b). We cannot disturb the Board's factual determinations unless we conclude that the evidence is undisputеd and leads inescapably to a contrary result. Eastham v. Whirlpool Corp. (1988), Ind. App.,
Issue One: Occupational Disease or Injury
Duvall maintains that the Board erred when it found that her carpal tunnel syndrome was not an occupational disease. Duvall urges us to hold that carpal tunnel syndrome is an occupational disease because her repetitive motion injury flowed as a natural risk out of her employment. ICI responds that our courts have previously determined carpal tunnel syndrome is not an occupational disease and that no extension or modification of Indiana law is warranted under these circumstances. See Star Publishing Co. v. Jackson (1944),
The Indiana Occupational Diseases Act defines an "occupational disease" as follows:
"(a) As used in this chapter, "occupational disease" means a disease arising out of and in the course of the employment. Ordinary diseases of life to which the general public is exposed outside of the employment shall not be compensable, except where such diseases follow as an incident of an occupational disease as defined in this section.
(b) A disease arises out of the employment only if there is apparent to the rаtional mind, upon consideration of all of the cireumstances, a direct casual connection between the conditions under which the work is performed and the occupational disease, and which can be seen to have followed as a natural incident of the work as a result of the exposure occasioned by the nature of the employment, and which can be fairly traced to the employment as the proximate cause, and which does not come from a hazard to which workers would have been equally exposed outside of the employment. The disease must be incidental to the character of the business and not independent of the relatiоn of employer and employee. The disease need not have been foreseen or expected but after its contraction it must appear to have had its origin in a risk connected with the employment and to have flowed from that source as a rational consequence."
IND.CODE § 22-8-7-10. Duvall reasons from this definition that since ICI stipulatеd to the causal connection between her carpal tunnel syndrome and her employment at ICI, and the Board adopted that stipulation, the Board was required to find that carpal tunnel syndrome is an occupational disease. We cannot agree.
The definition of an "occupational disease" found in Indiana Code § 22-3-7-10 is incоmplete because it assumes that the employee suffers from a "disease" and focuses on whether the disease is causally connected to workplace conditions. "Disease" is not defined in the Indiana Occupational Diseases Act, nor have our cases squarely confronted what constitutes a disease under the Act. Duvall hаs established by stipulation that her carpal tunnel syndrome is causally connected to her occupation, but that causal relationship does not require the conclusion that carpal tunnel syndrome is an occupational disease. Therefore, the first question before us is whether Duvall's carpal tunnel syndrome is a disease.
In construing а statute, we examine and interpret the statute as a whole, giving words their common and ordinary meaning. Spaulding v. International Bakers Services, Inc. (1990), Ind.,
The statutory definition describes an occupational disease in terms of a worker's "exposure" to conditions in the workplace. Specifically, the definition provides that a disease is an occupational disease when it results from "exposure occasioned by the nature of the employment." I.C. § 28-8-7-10(b) (emphasis added). The term "exposure" indicates a passive relationship between the worker and his work environment rather than an event or occurrence, or series of occurrences, which constitute injury under the Worker's Compensation Act. Duvall's carpal tunnel syndrome did not result from exposure to workplace conditions at ICI but resulted from the hand and wrist mechanics associated with Duvall's work on ICI's production line. Her carpal tunnel syndrome did not result from where she worked but from the work shе did.
Moreover, carpal tunnel syndrome is in a class of disorders described as "cu *1126 mulative trauma disorders." As a disorder caused by trauma, carpal tunnel syndrome is not a disease. A trauma is defined as a "wound, especially one produced by sudden physical injury." American Heritage Dictionary of the English Language at 1866 (1981) (emphasis added). Similarly, a "traumatism" is an "injury" or a "wound produced by injury; trauma." Id. Thus, by definition, the term trauma is synonymous with injury, and the cumulative effect of more than one trauma is likewise an injury.
We rely upon our supreme court's decision in Evans v. Yankeetown Dock Corp. (1986), Ind.,
Our recent decision in Union City Body Co. v. Lambdin (1991), Ind.App.,
Duvall's carpal tunnel syndrome resulted from trаuma to the carpal tunnel in her wrist produced by the repetitive, day-to-day motions she was required to perform as part of her job at ICI. Each motion and trauma, while incremental in its effect, resulted in the cumulative trauma disorder of carpal tunnel syndrome as though the trauma had occurred as a discrete event. See Nichiporchik,
Further, "injury" is defined by the Worker's Compensation Act as "only injury by accident arising out of and in the course of the employment and doles] not include a disease in any form except as it results from injury. IND.CODE § 22-3-6-1(e) {emphasis added). Thus, even assuming carpal tunnel syndrome were a disease, it would properly be designated as an "injury" under the Worker's Compensation Act because it results from injury, which is trauma to the carpal tunnel of the wrist.
Although we should construe the Oceu-pational Diseases Act liberally, we should not extend the Act to embrace cases which cannot reasonably be interpreted to fall within its scope. See Reid v. Ontario Manufacturing Co. (1947),
Issue Two: Statute of Limitations
We must next determine whether the Board properly concluded that Duvall's claim, as a claim for work-related injury, is barred by the two-year statute of limitations for such claims. See IND.CODE § 22-8-8-8. Duvall contends that her claim was timely filed on September 23, 1987, her last workday at ICI. She reasons that because her carpal tunnel syndrome condition is injury from reрetitive traumas, her claim acerued on the day of her "accident" which was the last day she could work at ICI. She further reasons that she could not determine the permanence of her injury until ICI terminated her employment because of her injury. We disagree with Duvall and conclude that the Board did not err when it found that Duvall's claim was barred by the statute of limitations.
As we noted in Issue One, our courts no longer require that a job-related injury arise from an accident as an occurrence or a discrete event. See Evans,
Therefore, the Board was required to determine when Duvall was first able to discern that the cumulative effect of her work-related activities had resulted in her injury. The evidence shows that Duvall was first diagnosed with carpal tunnel syndrome in 1983, and that in 1984, her physician placed her on a treatment regime and work restrictions. Record at 254-55 and 259. With that diagnosis, the cumulative effect of Duvall's work demands were discernible as an injury.
Duvall's argument that her injury was not discernible until she was terminated from employment is creative but uncon-vinecing. The statute of limitations for an injury under the Worker's Compensation Act is determined by when the injury is discernible, not by when the employee's condition prevents her from earning full wages. Compare IND.CODE § 22-3-3-3 and Lambdin,
In 1991, Duvall filed an adjusted claim for benefits arising from her carpal tunnel syndrome. The Board correctly concluded that Duvall's adjusted claim was barred by the statute of limitations because she filed that claim more than two years after her carpal tunnel syndrome first became discernible.
The decision of the Worker's Compensation Board is affirmed.
Notes
. Carpal tunnel syndrome is "a complex of symptoms resulting from compression of the median nerve in the carpal tunnel, with pain and burning or tingling parathesias in the fingers and hand, sometimes extending to the elbow." The Sloane-Dorland Annotated Medical-Legal Dictionary at 689 (1987). Carpal tunnel syndrome may follow from either major or minor trauma to the wrist or hand and often results from work activities that require continuous repetitive motion оf the hand. 4B Lawyer's Medical Cyclopedia § 31.422, at 190 (James G. Zimmerly ed., 3d ed. 1989).
. Both parties cite Jackson as a carpal tunnel syndrome case but we do not rely upon Jackson. While the employee in Jackson exhibited symptoms which are now commonly associated with carpal tunnel syndrome, the weight of medical evidence presentеd supported the conclusion that the employee suffered from a neurosis caused by an ongoing dispute between him and his supervisor. See id. at 223,
. We applied a similar analysis and reached the same result in American Maize Products Co. v. Nichiporchik (1940),
