This appeal arises pursuant to the Texas Workers’ Compensation Act, TEX. LAB. CODE ANN. § 401.001 et seq. (1989 Act). A contested case hearing was held on October 22, 2001. The appellant (carrier) appeals the hearing officer’s determination that the respondent (claimant) sustained a compensable occupational disease injury (carpal tunnel syndrome (CTS)) on __________. The claimant files a response, urging affirmance.
DECISION
Affirmed.
The issue in this case involved a factual determination for the hearing officer. The hearing officer is the trier of fact and is the sole judge of the relevance and materiality of the evidence and of the weight and credibility to be given to the evidence. Section 410.165(a). While a claimant’s testimony alone may be sufficient to prove an injury, the testimony of a claimant is not conclusive but only raises a factual issue for the trier of fact. Texas Workers’ Compensation Commission Appeal No. 91065, decided December 16, 1991. The trier of fact may believe all, part, or none of any witness’s testimony. Taylor v. Lewis, 553 S.W.2d 153 (Tex. Civ. App.-Amarillo 1977, writ ref’d n.r.e.); Texas Workers’ Compensation Commission Appeal No. 93426, decided July 5, 1993.
There is evidence in the record to show that the claimant was engaged in repetitive activity. Medical evidence supports the diagnosis of CTS that worsened over time. The claimant testified that her job required repetitive activities and that the CTS was a work-related injury. In a case such as the one before us where both parties presented evidence on the disputed issue, the hearing officer must look at all of the relevant evidence to make a factual determination and the Appeals Panel must consider all of the relevant evidence to determine whether the factual determination of the hearing officer is so against the great weight and preponderance of the evidence as to be clearly wrong or unjust. Texas Workers’ Compensation Commission Appeal No. 941291, decided November 8, 1994. An appeals-level body is not a fact finder, and it does not normally pass upon the credibility of witnesses or substitute its own judgment for that of the trier of fact even if the evidence could support a different result. National Union Fire Insurance Company of Pittsburgh, Pennsylvania v. Soto, 819 S.W.2d 619, 620 (Tex. App.-El Paso 1991, writ denied). Only were we to conclude, which we do not in this case, that the hearing officer’s determination was so against the great weight and preponderance of the evidence as to be manifestly unjust would there be a sound basis to disturb that determination. In re King’s Estate, 150 Tex. 662, 224 S.W.2d 660 (1951); Pool v. Ford Motor Company, 715 S.W.2d 629, 635 (Tex. 1986). Since we find the evidence sufficient to support the determination of the hearing officer, we will not substitute our judgment for his. Texas Workers’ Compensation Commission Appeal No. 94044, decided February 17, 1994.
We affirm the decision and order of the hearing officer.
The true corporate name of the insurance carrier is THE INSURANCE COMPANY OF THE STATE OF PENNSYLVANIA and the name and address of its registered agent for service of process is
CORPORATION SERVICE COMPANY
