Claimant injured her wrist while working for employer , and was *543subsequently fired for reasons unrelated to the injury. As a result of the work-related wrist injury, claimant was unable to earn her pre-injury wage. She was able to find a job as a sitter for an elderly woman, however, and thus was entitled to temporary partial disability benefits equal to two-thirds of the difference between her pre-injury wage and her wage as a sitter. See OCGA § 34-9-262. Then, in January 1993, claimant fell and broke her leg. Employer asserted that its obligation to pay partial disability benefits ceased at that point, because any disability subsequent to her fall was caused by her fall (which was not covered by workers’ compensation) rather than her wrist injury (which was covered by workers’ compensation). The administrative law judge and board accepted this assertion, ruling that employer was obligated to pay temporary partial disability benefits only until the time of the fall, and the superior court affirmed. We granted claimant’s application for discretionary appeal and now reverse.1

Citing Aden’s Minit Market v. Landon, 202 Ga. App. 219 (413 SE2d 738) (1991) and Evco Plastics v. Burton, 200 Ga. App. 121 (407 SE2d 60) (1991), employer argued that claimant bore the burden of proving that her post-fall inability to earn her pre-injury wage was caused by her work-related wrist injury; and the superior court based its affirmance on claimant’s failure to meet that burden. However, Landon and Burton only place this burden on the claimant when the claimant asserts a change in condition (i.e., the claimant is seeking a resumption of benefits after a period in which she was not entitled to them). In this case, it is now undisputed that claimant’s disability was caused by her work-related injury up until her fall, so she was entitled to disability benefits until then. Thus, it was the employer rather than claimant who sought to show a change of condition, and the employer rather than claimant who bore the burden of proof on causation. See Johnson Controls v. McNeil, 211 Ga. App. 783, 785-786 (1) (440 SE2d 528) (1994).

In McNeil, we held that where it could not be determined from the evidence whether an initially disabling injury continued to be disabling, the employer had failed to meet its burden of proving a change in condition, and the claimant’s disability benefits should have continued. As in McNeil, the record here does not show how long the disability caused by the covered wrist injury continued.2 *544Therefore, claimant’s temporary partial disability benefits should continue until the date employer can prove claimant is able to earn her pre-injury wage or that her inability to earn such a wage is not caused by her covered wrist injury.

Judgment reversed.
