Definitions

  • the present invention relates to the field of electromedical devices.
  • it relates to a portable electronic device capable of acquiring and processing data related to physiological parameters during a session of physical and/or sporting activity.
  • this monitoring activity is carried out while performing predefined tests, to be carried out according to methods repeatable over time.
  • the ability of a subject to perform a given physical exercise constitutes, in fact, an important indicator of the efficiency of the cardiovascular and respiratory system, and of the body as a whole.
  • Measuring this ability is important in order to assess the impact of given pathologies on the body or to develop methods to manage patients suffering from chronic pathologies. For example, assessing the level of tolerance to calibrated stress is a valid aid in order to build an accurate clinical picture for patients affected by respiratory or cardiovascular pathologies, or those who have undergone an organ transplant.
  • walking test during which the subject walks at maximum speed for a predefined distance.
  • This type of test is commonly used to detect pathologies compensated at rest and in rehabilitation. It is also used in maximal running, above all in sports medicine.
  • One of these walking tests is the “Six Minute Walking Test” (or 6mWT). This test is currently widely used in order to assess the distance travelled by a subject in six minutes. This test is sufficiently reliable, given that a direct proportionality between the distance travelled during the test and the subjective condition of wellbeing of a subject has been proven experimentally.
  • the 6m WT is generally used to assess the treatment of patients suffering from respiratory, cardiovascular or neurological pathologies, or in rehabilitation following organ transplants.
  • This test has the advantage of being simple, repeatable and of requiring minimum equipment, besides being well-tolerated and representative, in terms of physical stress, of the subject's daily activities, and hence of his or her quality of life.

  • ⁇ is equal to zero.
  • the value of K is normally always constant for a distance from 50 to 100 m per minute (in correlation to step length, contractile efficiency of the muscle and elastic properties of the connective tissues), and hence cannot be taken into account.
  • the parameter T is a time constant of six minutes for the 6m WT.
  • the 6m WT is performed with the aid of simple instruments, such as a watch or a system for calculating the distance travelled.

  • the document WO2006/105341 describes a device for monitoring the physical condition of a subject.
  • it comprises a pedometer to assess the distance travelled and a microprocessor to process signals related to physiological parameters coming from external measurement devices.

  • Another object of the present invention is to provide an electromedical device which allows reliable, repeated and frequent measurement of the subject's performance during the physical- sporting activity, hence suitable for maximal running tests with programmed time or distance or fixed rate step tests (for example to calculate the IRI - Immediate Recovery Index).

Usually, however, the inhaling and exhaling phases, in patients with pulmonary problems, do not allow measurement of small changes in phase and, therefore, do not allow measurement of small quantities of volume breathed.
