Definitions

  • This invention relates to the detection of body activity, such as sleep patterns, and the analysis of data related to such functions for provision to a user.
  • WO-A-9714354 discloses a device and corresponding method which collects data for analysing sleep disturbances so that such data can be interpreted by a specialist at a future date.
  • this type of device requires operation by a highly skilled user and provides analysis which is difficult to interpret by anybody other than a specialist, as well as being expensive and sometimes unreliable. Furthermore, it is unable to provide a detailed history over an extended time period for an individual.
  • a method for monitoring body activity comprising the steps of:
  • analysing the actimetry data to provide advisory information comprises the steps of: determining parameters based on the actimetry data;
  • AQI is the "activity quality index”
  • n is an integer greater than 1
  • C f is a set of constants
  • Pj is the set of parameters, the parameters being at least one from the group of activity duration, activity efficiency, activity latency, activity bouts, number of activity interruptions and mean activity score; and outputting the advisory information.
  • the body activity being monitored may be sleep, and/or waking activity.
  • the data including temporal information, may be stored prior to the analysis step. Both actimetry information and temporal information may be used in the analysing step.
  • the advisory information may include an indication of the quality of the activity, such as whether or not the duration of the activity is sufficient, an indication as to whether the total amount of the activity over an extended period is acceptable, as well as other data related to other long term body activity, for example.
  • the device can be configured to detect activity during the day.
  • the body activity that is measured can, as well as being actual time slept, be the number of awakenings, an indication as to how intermittent the sleep was, time taken before sleep, the number of and length of sleep interruptions, sleep proficiency, the number minutes immobile/moving, etc. A selection or all of this information can be provided to identify the least and most active times during the day.
  • the advisory information may include a comparison of the data with peer group data, statistical analysis, history data and solution/product choice to provide an improvement in activity quality or duration.
  • the data received may be collected by one or more additional sensors to also measure body pulse rate variability, blood pressure variability or other body activities such as eyelid movement or respiration.
  • sleep phases such as REM, slow light sleep, slow deep sleep, or paradoxical sleep may be monitored.
  • Additional data may be provided to the analysing step by a human operator.
  • the invention is described for use in monitoring sleep patterns, however, it may also be of use in monitoring alternative body activities. For example monitoring daily activity levels to indicate whether the user is achieving sufficient activity in a fitness regime, whilst on a diet, during recuperation or, when bed rest is necessary, the level of activity of a patient determines whether bed sores will be prevented. A further example may be to study the activity of children who suffer attention deficit syndrome. There are many other scenarios where the standard method could be used to monitor the activity of people or even pets.
  • the method could be used to monitor the heart rate either during sleep, to determine the different phases of sleep or during sports activities to monitor the heart rate without the need for any cumbersome chest band.
  • the method could also be used to determine how stressed somebody was and potentially warn of impending heart problems.
  • the constant C may be 52.42 and the constants C-, associated with each of the parameters Pi respectively may be -1.887, 0.572, 2.084, -0.3536, 0.1408, -0.018, 0.188, -0.2469, -1.2126, -0.226, -0.0112 and 0.001238.
  • a computer readable storage medium comprising instructions for performing the steps of the method may be provided according to the present invention.
  • a computer configured to perform the steps of the method may be provided according to the present invention.
  • Figure 1 is a schematic, perspective view of components of a system which may provide data for a method of the present invention
  • Figure 2 is a schematic diagram showing some of the functionality of the system of Figure 1 ;
  • Figure 3 to 6 are diagrams showing possible displays from the system of Figure 1 ;
  • Figure 7 is a schematic diagram of the internal components of the system of Figure 1 ;
  • a system which may be used to collect data for the method of the present invention has, in this example, a monitoring device 1 configured as a wrist watch-style device, with a strap 2 and a component-containing housing 3.
  • a monitoring device 1 configured as a wrist watch-style device, with a strap 2 and a component-containing housing 3.
  • a display 4 On the outer surface of the housing 3 is an optional display 4, which in this case is a liquid crystal display.
  • the system may further comprise a receiving device 5, often referred to as a docking station which, in use, can receive the monitoring device 1 and connect with it to retrieve data from the device 1.
  • the receiving device 5 may be, in turn, connected to an analysing device 6, which in this case is an appropriately configured PC, although it could be a dedicated piece of hardware.
  • the receiving device 5 and analysing device 6 are shown as separate components, although this may not necessarily be the case.
  • the analysing device 6 has its own display 7, and may optionally have the ability to connect to a remote terminal (not shown) via an internet link or some other form of communication device.
  • the device 1 of Figure 1 has a number of internal components.
  • the device 1 is powered by a battery 10 (or another power supply) which supplies power to the other components of the device 1.
  • An actimetry sensor 11 detects motion in the device 1 and hence motion in the body to which the device 1 is attached in use.
  • the data from the actimetry sensor 11 is passed to a memory 12.
  • a clock 13 also provides temporal data to the memory 12 and to the actimetry sensor 11 if necessary, as well as optionally to the display 4.
  • the device 1 may further comprise additional sensors 15, 16, which may detect blood pressure, pulse rate variation etc. Data from these additional optional sensors 15, 16 may also be forwarded to the memory 12.
  • the monitoring device 1 has the ability to send data to the receiving means 5 via a transmitter 20, in this case through a fixed connection between the two when the user places the monitoring device 1 in the receiving device 5.
  • the monitoring device 4 may transmit and/or receive data from the receiving means 5 via a wireless link such as an infra red link.
  • data from the memory 12 can be requested from analysing means 6, either on a regulated intermittent, continuous, or on a user-requested basis.
  • the actimetry sensor 11 may provide information in relation to sleep duration and the type of sleep to the analysing means 6.
  • This information can be analysed by the analysing means 6 to provide information to the display 4, simply in terms of the total number of hours of sleep obtained, although it may provide additional information in relation to the quality of the sleep and the expected value of that sleep in terms of an "energy bank”.
  • the analysing means 6 may also provide information indicative of accumulated sleep deficit or sleep excess.
  • the data can be provided to a user as and when requested, and is arranged to be provided in a very simple format so that it does not need complex interpretation.
  • the analysing means 6 may employ a scale, for example the Stanford sleep scale, in order to score the monitored, sleep and provide relevant information to the user and to some subject we input from the user.
  • the scale defines different levels of sleepiness as follows;
  • This scale can be shown to a user so that the user can input an indication of how tired they consider themselves to be. For example, the user could be prompted to input an indication as to how they feel when they wake up, with an indication as to the reasons for their feelings being provided by the analysing means 6 from the data collected.
  • such an input could be employed during the initial weeks of employing the device to help the system determine whether or not the user is sleeping for the right amount of time for them. For example, on the first day of wearing the device the system may prompt the user to indicate how much sleep they consider they need. It could then provide information regarding the average sleep requirement for someone of their age and sex. However, as the requirements vary from user to user, the system can then monitor sleep over a given period and prompt the user for feedback, not only at the time during the day in order to form a sleep diary in the memory of the system. The system may then be configured to adapt the indications that it gives the user, based upon the feedback and wake the user at the appropriate time, and then employing a sleep bank once the user's particular requirements have been determined.
  • the device 1 may have an alarm 18, which can be used simply to wake the user, in the manner of a normal wrist watch alarm, although it may be activated by the analysing means 6 (in conjunction with a heart rate monitor), when it is detected that an appropriate type of sleep is occurring to ensure gentle waking of the user.
  • an alarm 18 can be used simply to wake the user, in the manner of a normal wrist watch alarm, although it may be activated by the analysing means 6 (in conjunction with a heart rate monitor), when it is detected that an appropriate type of sleep is occurring to ensure gentle waking of the user.
  • additional sensors 15, 16 are provided then additional analysis can be performed dependent upon the type of sensor to provide additional or more detailed and accurate information to the user. If the sensors detect parameters external to the body, such as light, location, sound, air temperature, humidity, barometric pressure, then this information may be compared with information relating to body activity in order to adjust their information. If the sensors determine additional body activity, and detect one or more of muscle tonus, skin temperature, galvanic skin response, etc then additional analysis of the quality of the sleep may be provided.
  • parameters external to the body such as light, location, sound, air temperature, humidity, barometric pressure
  • this information may be compared with information relating to body activity in order to adjust their information. If the sensors determine additional body activity, and detect one or more of muscle tonus, skin temperature, galvanic skin response, etc then additional analysis of the quality of the sleep may be provided.
  • a blood pressure sensor is employed then additional indications related to general levels of health and activity not specifically related to sleep alone can be provided by the analysing means. If a pulse rate variability detector is employed then this can assist in determining the type of sleep detected, and can provide further information in relation to whether an acceptable level of aerobic exercise has been performed within the allotted time period, whether it be a day, a week or a month.
  • the analysing means 6 has a line to a remote station, more complex analysis can be performed and it may be possible for the analysing means 6 also to request and obtain data from a human specialist or an extended database so that additional information can be provided to the user.
  • the system enables the storage of long term data in such a manner that it can be tracked to give a high quality user history for treatment, as well as for identifying long term trends that would not come to light in a short term analysis.
  • the additional analysing means 6 may not be provided.
  • the receiving device (or docking station) 5 may be configured to perform the analysis procedure, whilst the level of analysis would necessarily be less comprehensive than the analysing means 6, due to the reduced processing capacity, the unit still provides a useful function to the user.
  • the docking station 5, illustrated in figure 5, is provided with a display 31 and two control knobs 33,34 to enable the user to select and display information from the analyses performed by the unit 5.
  • Recess 32 is provided to locate the sensor device 1 in the correct relative position to assist in downloading the information stored within it.
  • the sensor device 1 will be initialised in the docking station 5 prior to use (i.e. before bed time).
  • the docking station 5 comprises its own internal clocking mechanism and hence removing the sensor device 1 from the recess 32 on the docking station 5 will automatically provide "bed time” information.
  • “wake time” will automatically be recorded when the sensor device 1 is replaced into the recess 32 of the docking station 5 the following morning.
  • the monitoring device 1 may not comprise a storage facility 12.
  • the data acquired by the actimetry sensor would be transmitted directly to the docking station 5 for storage in real time.
  • the docking station 5 is a highly portable unit that may easily be taken periodically, typically fortnightly, to an expert sleep analyst for further interrogation and more detailed advice.
  • a download facility is provided within the docking station 5 to further assist in this interrogation process.
  • the sleep expert will provide a more detailed analysis of the user's sleep patterns. For example, in order to provide a measure of sleep quality, as described above, a parameter "Sleep Quality Index” (SQI) may be provided.
  • SQI Session Quality Index
  • the algorithm for this parameter, SQI is based upon many of the parameters which are easily monitored, or derived, by the invention.
  • the algorithm is of the form
  • Corresponding constants may be defined by the values 52.42, -1.887, 0.572, 2.084, -0.3536, 0.1408, -0.018, 0.188, -0.2469, -1.2126, -0.226, -0.0112, 0.001238.
