Abstract

Objectives: Tremor due to hypermetabolism is a classic finding in hyperthyroid patients. Over several decades of clinical practice, Dr. Shigeaki Hinohara noted the possibility that hyperthyroid diseases may be detected by tremor-induced measurement fluctuations while being weighed on conventional scales. The purpose of this study was to assess the difference in detectable tremor using a specialized scale between patients with probable hyperthyroidism and those without.

Methods: A prospective cohort study was conducted from June 2010 to March 2011 at The Center for Preventive Medicine, St. Luke’s International Hospital, Tokyo Japan. We developed a weight scale that also digitally measured the horizontal and vertical degree and amplitude of patients’ tremor. Prior to the measurement, informed consent was obtained from all participants. Subjects were then asked to undergo this weight measurement in order to measure tremor. Hyperthyroidism was diagnosed using TSH (<=0.44) and FT4 (>=1.4). Student t-test was used to analyze significant differences in strength of tremor between those with and without hyperthyroidism

Results: A total of 1583 patients participated in this study. Of these, 125 patients had hyperthyroidism based on TSH and FT4 results. There were no significant differences in any tremor measurements between patients with hyperthyroidism and those without.

Conclusion: Using a specialized scale to measure tremor, no significant differences were seen between patients with hyperthyroid diseases and those without. The use of weight scales that quantify tremor appears to be unsuitable for detection of hyperthyroidism.
