An Ergonomic Case Study of a person with De Quervain's Tenosynovitis Relating to the use of a Mobile Telephone

Abstract

This article consists of a case study analysing the ergonomic influence of the mobile telephone with relevance to De Quervain's tenosynovitis. The prime causative factors were identified as hand position, frequency of dialling and static postures. Critical analysis of each of these components is presented, along with the physiological implications and current work regulations. Treatment discussed includes change of telephone technique, rest, education, trigger-point release, heat, exercise and stretches. The importance of ergonomic changes to decrease De Quervain's is highlighted.
