The claimant was hit by a forklift while operating a forklift, and alleged the accident caused a back injury. Through employer witness testimony and medical testimony, we showed that the claimant did not sustain a back injury, and that her medical issues were pre-existing and unrelated to the accident. The judge found that the evidentiary evidence presented by the employer established that, even though the claimant was involved in a forklift incident, the claimant did not sustain a work injury, and her ongoing medical issues are unrelated to the forklift accident.
