AB  - BACKGROUND: The six-minute walk test (6MWT) is an established measure of 
      functional exercise capacity associated with clinical prognosis in Chronic Heart 
      Failure (CHF). The aim of this study is to evaluate the employment of 
      tele-accelerometry for the remote assessment of 6MWT in CHF. METHODS: 155 
      patients were subjected to tele-accelerometry in form of monthly 6MWTs in their 
      home surroundings. Accelerometer output included steps/6 min and walking speed. 
      Data was directly transferred via mobile network to the Telemedicine Centre 
      subsequent to test completion. 6MWT distance was measured by hand wheel and steps 
      were counted with a digital hand-counter at baseline (Test 1) and at 12 months 
      follow-up (Test 2). RESULTS: Accelerometer accuracy was within the 99th 
      percentile. There was a significant correlation between step count, walking speed 
      and measured 6MWT distance (Test 1: steps: r=0.80, P<0.001; Test 2: steps: 
      r=0.90, P<0.001 and Walking Speed Test 1: r=0.80, P<0.001; Walking Speed Test 2: 
      r=0.86, P<0.001). The reproducibility of tele-accelerometry was within 95% margin 
      for all performance parameters, which showed stronger associations to quality of 
      life questionnaire (Short Form - 36) Physical Component Score (PCS) than New York 
      Heart Association (NYHA) functional class. CONCLUSION: Tele-accelerometry is 
      feasible in patients with CHF and output parameters are indicative of exercise 
      capacity. The benefit of this approach lies in its simplicity under every day 
      circumstances by enabling routine performance testing to assess patients' 
      functional status.
