OPINION OF THE COURT
Progress begets promise and problems. Computer technology has ushered in the "information age” and helped to create a global workplace that is accessible from one’s home or office. These cases present us with a difficult question arising from the widespread use of computers in the workplace: when does a cause of action accrue against a keyboard manufacturer for repetitive stress injury (RSI) suffered by a keyboard user? We conclude that, in such cases, the cause of action accrues upon the onset of symptoms, or the last use of the keyboard, whichever is earlier.
I.
This appeal involves over 90 separate plaintiffs suing various keyboard manufacturers in a number of separate lawsuits. By order entered January 22, 1993, Administrative Judge Stanley Ostrau, in apparent recognition of the large number of RSI cases which were making their way through Supreme Court, New York County, assigned all cases involving RSIs to Justice Stephen Crane for pretrial purposes. Soon thereafter, Justice Crane established procedures for the joint briefing of various *765 legal issues. Defendants’ motions raising Statute of Limitations issues were treated as dismissal motions made pursuant to CPLR 3211 (a) (5).
Most of the pleadings in the cases before us on this appeal contain common allegations with respect to the onset and manifestation of plaintiffs’ RSIs. Each plaintiff outlines his or her history of keyboard use, including, to the extent known, the particular keyboards used. The pleadings then go on to state that plaintiffs’ injuries were "insidious in their onset,” such that "it is not possible to identify [either] the precise date of the onset of symptoms,” or to say "that any initial symptoms experienced constituted the full manifestation or even partial manifestation” of the injury. Nevertheless, the plaintiffs do identify dates upon which they began experiencing some symptoms, such as numbness, tingling, pain and/or sensory motor impairments of the upper extremities, neck and torso. Plaintiffs further state the dates upon which they were diagnosed with various RSIs. Finally, the pleadings generally allege that the nature of each plaintiff’s injury is "such that there is no precise moment of injury,” but rather a "cumulative and prolonged process by which [each] plaintiff sustained injury [and] aggravated [an] existing injury.”
RSI is one of several essentially synonymous terms, all of which "connote injury to the musculo-skeletal tissues from repeated motions and exertions” (Russ, Freeman and McQuade, 5 Attorney’s Medical Advisor § 66:4, at 66-8). RSIs can be caused by activities as divergent as playing video games or working a jackhammer. Carpal tunnel syndrome, probably the most prevalent keyboard-related injury, is a subcategory of RSI involving compression of the median nerve as it passes through the wrist between the flexor tendons and the transverse carpal tunnel ligament (the area known as the carpal tunnel) (Ausman and Snyder, 3 Medical Library Lawyer’s Edition § 4:18, at 53 [1989 ed]). While carpal tunnel syndrome can have a number of causes, ranging from arthritis or benign tumors to blunt trauma, the condition is seen with increasing frequency as a result of workplace use of keyboards. Indeed, according to various surveys, the occurrence of RSIs among workers rose roughly 1,000% between 1982 and 1991, to the point that today they account for 61% of all workplace illnesses (see, Comment, Cumulative Trauma Disorders: A Hidden Downside to Technological Advancement, 11 J Contemp Health L & Pol’y 479; Juge, Stokes and Pine, Cumulative Trauma Disorders — "The Disease of the 90’s”: An Interdisciplinary Analysis, 55 La L Rev 895).

In deciding what accrual rule to apply to these claims, the trial court felt compelled to follow
Wallen v American Tel. & Tel. Co.
(Sup Ct, Bronx County, Sept. 17, 1992, Saks, J., index No. 12336/91,
affd for reasons stated below
While the Appellate Division found our toxic torts cases to be controlling, it also held that CPLR 214-c (providing a discovery rule in toxic torts cases) was inapplicable. The Court recognized the harshness of the rule it had pronounced, but held that the remedy, if there was to be one, lay with the Legislature rather than the courts.
II.
At the outset, we agree with the Appellate Division that CPLR 214-c is inapplicable in this case. CPLR 214-c was enacted in 1986 as part of a larger "tort reform” package (L 1986, ch 682), and provides that "the three year period within which an action to recover damages for personal injury or injury to property caused by the latent effects of exposure to any substance or combination of substances * * * must be commenced shall be computed from the date of discovery of the injury by the plaintiff or from the date when through the exercise of reasonable diligence such injury should have been discovered by the plaintiff, whichever is earlier.” (CPLR 214-c [2].) CPLR 214-c was enacted to abrogate the exposure rule which this Court had formulated and adhered to in a line of cases stretching from
Schmidt v Merchants Desp. Transp. Co.
(
While CPLR 214-c is a remedial statute and as such, should be interpreted broadly, this maxim does not allow us to stretch the statute beyond its intended coverage. "[E]ven a remedial statute must be given a meaning consistent with the words
*767
chosen by the Legislature”
(Enright v Lilly & Co.,
We also reject plaintiffs’ contention that the continuing duty to warn doctrine may be applied to extend the limitations period. The gravamen of plaintiffs’ claims is that defendants’ keyboards were defectively designed. In the analogous case of liability predicated upon a negligent act, this Court in
Schwartz v Heyden Newport Chem. Corp.
(
III.
CPLR 214 provides that an action for damages for personal injuries "must be commenced within three years.” A cause of action accrues for purposes of CPLR 214 "when all of the facts necessary to the cause of action have occurred so that the party would be entitled to obtain relief in court”
(Aetna Life & Cas. Co. v Nelson,
In
Martin v Edwards Labs.
(
The second line of cases is typified by
Flanagan v Mount Eden Gen. Hosp.
(
Martin
characterized the type of claim at issue in
Flanagan
as one based upon objects being implanted, but not assimilated, into the body. We reasoned that a discovery rule was justified in such cases based upon a balancing of typical Statute of Limitations policies. Specifically, we noted that there was little danger of feigned claims since the objects retained their identity within the body; that for the same reason the defendant was not unduly handicapped in defending such claims; that there was little or no possible causal break between the negligence and the injury; and that the claim did not rest to a significant degree on questions of credibility or professional diagnostic judgment
(Martin v Edwards Labs., supra,
The third line of cases identified in
Martin
is typified by
Victorson v Bock Laundry Mach. Co.
(
Martin
itself involved claims against the manufacturer of a defective heart valve, and a defective Daikon Shield. Even though these products were intended to be inserted into the body, and thus would seem to have fit into the second line of cases, we held that the third line of cases was controlling
(Martin v Edwards Labs., supra,
Our conclusion that the implantation cases in
Martin
fell within the third category was reached after a careful evaluation of the various policy considerations underlying Statutes of Limitation. The Court noted that a discovery rule was not necessary in implantation cases, since "the implantation or insertion is with the recipient’s knowledge and consent, knowledge which he or she can pass on to a physician seeking to diagnose the cause of later developing bodily problems”
(Martin v Edwards Labs., supra,
Martin
also noted that the age of the claim would not present a great problem, because unlike assimilated substances, "[i]f through malfunction the product is thought to have caused harm, it can in most cases be removed and examined to ascertain whether in fact it malfunctioned and, if so, whether that was the cause of the harm”
(Martin v Edwards Labs., supra,
A computer keyboard is not a toxic substance which is ingested into the body, nor is it an object implanted, but not assimilated, into the body. However, unlike a typical case involving products remaining outside of the body, there is no one readily discernible first date of injury in RSI cases. Thus, these claims would not appéar to fit neatly within any of the three categories identified in Martin. It follows that this case requires us to strike a new balance with respect to the competing policy interests at stake in order to correctly determine the accrual question. However, given the analogies which may be drawn between this type of case and an exposure case, as identified by both the parties and the Court below, any principled balancing necessarily must take into consideration our holdings in the exposure cases.
IV.
The "first exposure” rule has its roots in
Schmidt v Merchants Desp. Transp. Co.
(
In
Schwartz v Heyden Newport Chem. Corp.
(
Admittedly, there are similarities between toxic tort and repetitive stress injuries which would militate in favor of applying the same accrual rule in both types of cases. In each case, the plaintiffs appreciable injury does not manifest itself until some time after (and in many cases significantly after) initial exposure to the product. Thus, in both types of cases there is a gap between the manufacturer’s breach of duty and the resulting ultimate injury to the plaintiff. As we recognized in Consorti v Owens-Corning Fiberglas Corp. (supra), this injects a substantial degree of uncertainty into a manufacturer’s risk assessment calculation, and may give rise to significant problems of proof. Thus, in Consorti, we made clear that our rejection of a fact-based date of manifestation of injury test
"was made for practical and policy reasons articulated in the developing case law, that is, the need to provide manufacturers, employers and other economic actors who are potential defendants with a degree of certainty or predictability in assessing the risk of liability and to avoid stale claims which often turn on questions of credibility or disputed medical judgments. Therefore, a bright line, readily *772 verifiable rule was adopted in which, as a matter of law, the tortious injury is deemed to have occurred upon the introduction of the toxic substance into the body.” (Id., at 451-452.)
These same policy considerations would appear to point to the adoption of a first exposure rule in this case. Like a toxic tort, RSI may not develop until years after a person first uses a keyboard; indeed, according to plaintiffs’ expert, the condition may not develop at all, or not until after one keyboard is discarded and a person subsequently uses different keyboards.
This Court has refused to waver from the first exposure rule where the policy considerations articulated in Consorti have dictated its application. "While recognizing that the rule may seem unjust, we have generally left ameliorative efforts to the Legislature. Indeed, where the Legislature has deemed it necessary, it has abrogated the exposure rule (see, e.g., CPLR 214-b [agent orange exposure]; CPLR 214-c [toxic torts]). Thus, defendants argue, given that the Legislature has, in fact, modified our accrual jurisprudence where it has deemed fit, this Court should leave the exposure rule in place, and allow the Legislature to modify it further if it so chooses. We reject this argument as applied in this case.
The exposure rule is premised upon the proposition that, while injury is necessary for the accrual of a cause of action, injury in a toxic tort case accrues upon exposure to the toxic substance, because it is at that point that there has been "a wrongful invasion of personal or property rights”
(Schmidt v Merchants Desp. Transp. Co., supra,
Defendants are correct that we have long given deference to the Legislature to recast the accrual methodology of toxic torts if it saw fit and as noted earlier, the Legislature has on several occasions done so. However, in cases such as this, where we are presented with new categories of tort claims and injuries, we have always done a careful and balanced analysis of the nature of the claim and its intricate interplay with the policy considerations at the heart of our Statute of Limitations jurisprudence
(Martin v Edwards Labs., supra,
V.
Statutes of Limitation were "designed to promote justice by preventing surprises through the revival of claims that have been allowed to slumber until evidence has been lost, memories have faded, and witnesses have disappeared”
(Telegraphers v Railway Express Agency,
In examining the policies underlying Statutes of Limitation, this Court has emphasized both a defendant’s interest in repose and "in defending a claim before his ability to do so has deteriorated through passage of time”
(Martin v Edwards Labs., supra,
Weighing these competing policy considerations, we conclude that the proper rule in RSI cases is that the cause of action accrues against a given manufacturer upon the onset of symptoms or the last use of the injury-producing device, whichever is earlier
(see, Piper v International Bus. Machs. Corp.,
We reject plaintiffs’ argument that accrual should be measured not from the time they experienced RSI symptoms, but from the date they actually became aware of the nature of their injuries. A date of diagnosis test would give a plaintiff "the power to put off the running of the Statute of Limitations indefinitely”
(Snyder v Town Insulation,
Judicial economy and the possibility of feigned claims militate in favor of some type of first use rule. However, it is likely that a plaintiff will seek medical treatment when the injury manifests itself in the form of RSI or pre-RSI symptomatology. This significantly reduces the possibility of a plaintiff indefinitely postponing or feigning a claim, since in the majority of cases there will be objective evidence of the onset of symptoms in the form of medical or work records. Although plaintiffs contend they are not able to identify a date for the onset of RSI symptoms, they have alleged a date on which the signs /symptoms of RSI were manifest. Requiring a symptom-based benchmark does not impose an inappropriate or unfair burden on plaintiffs.
Moreover, while an accrual period which bears some relationship to the onset of symptoms will certainly involve lower courts in limited factual inquiries, this was also true of the rule we adopted in
Martin v Edwards Labs. (supra,
Finally, the possibility of causal breaks between the claimed negligence and the injury is also a legitimate concern. However, the last use or onset of symptoms rule solves the causal breakdown problem, which is most pronounced in the case of keyboards used years prior to the onset of symptoms. For example, in one of the cases before us, Sharib, Heholt & DeForest v Zenith Data Sys. (Sup Ct, NY County, index No. 125155/93), plaintiff Heholt sues two different manufacturers of four different keyboards which she used from 1979 through 1992. She commenced her action on October 5,1993, and identifies April 1992 as the date upon which she began to experience some symptoms of RSI. Nevertheless, by suing the manufacturer of every keyboard she ever used, plaintiff implicitly alleges that each use of the defendants’ keyboards contributed to her condition. This includes the keyboard which she used from 1979 to 1984 with no symptomatology. Certainly there comes a point in time when the causal link between use and injury becomes too remote as a matter of law.
The rule we announce today will bar direct actions against such remote manufacturers. It strikes a proper balance between giving a plaintiff an opportunity to commence an action after becoming aware of a symptom of injury and providing certainty and predictability to manufacturers, employers and other economic actors in their risk assessment, while also avoiding stale claims.
In adopting this rule, we are also cognizant of the fact that problems of proof will be inherent in these cases whether we define accrual by reference to the first use of the device or by the onset of symptoms. Unless first use is defined as any touching of a keyboard whatsoever (which, as previously noted, bears no relationship to actual injury), then the problem in defining the moment of injury would become determining when a plaintiff began using a keyboard with any substantial regularity. In an increasingly technological world, exposure to com *776 puter keyboards and other devices with the potential to cause RSI has become commonplace. Given this reality, defining "first use” would pose equally serious, if not greater, difficulty. Having carefully considered the various competing concerns presented by this information age injury, we conclude that the balance is best struck by defining accrual of a cause of action for RSI as the earlier of the onset of symptoms or last use.
Accordingly, the order of the Appellate Division should be modified, without costs, the actions remitted for action in accordance with this opinion, and the certified question answered in the negative.
Chief Judge Kaye and Judges Titone, Smith and Ciparick concur; Judges Bellacosa and Levine taking no part.
Order modified, without costs, actions remitted to Supreme Court, New York County, for further proceedings in accordance with the opinion herein, and certified question answered in the negative.
Notes
It should be noted that defendants urged Supreme Court to adopt a rule similar to that which we announce today
