Productivity of transcriptionists using a treadmill desk.

OBJECTIVE: Time spent sitting increases all-cause mortality. Sedentary occupations are a major contributor to the obesity epidemic. A treadmill desk offers the potential to increase activity while working; however, it is important to make sure that productivity does not decline. The purpose of this study is to evaluate productivity while using a treadmill desk.

PARTICIPANTS: Eleven experienced medical transcriptionists participated in the study.

METHODS: Transcriptionists were given 4 hours training in the use of a treadmill desk. They were asked to transcribe tapes for 8 hours both while sitting and while using the treadmill desk. Speed and accuracy of transcription were compared as were the average expended calories per hour.

RESULTS: The accuracy of transcription did not differ between sitting and walking transcriptions. The speed of transcription was 16% slower while walking than while sitting (p < 0.001). The transcriptionists expended 100 calories per hour more when they transcribed while walking than when they transcribed while sitting (p < 0.001).

CONCLUSION: The treadmill desk offers a way to reduce sedentariness in the workplace and has potential to reduce employee obesity and health care costs. However, more than 4 hours of training will be necessary to prevent a significant drop in employee productivity.
