Definitions

  • the present invention relates to a measuring system and measuring device.
  • the present invention also relates to a watch into which the measuring device is integrated.
  • the present invention relates particularly to a measuring system and measuring device which are suitable for the analysis of tremors in Parkinson's patients.
  • Parkinson's disease is a progressive, degenerative neurological movement disorder. About 6.3 million people suffer from this disease worldwide. Although Parkinson's disease usually only manifests itself over the age of 65, 15% of patients already develop this disorder before the age of 50.
  • Parkinson' s disease progresses the debilitating effect of the disease increases and daily activities such as bathing or dressing and undressing become increasingly more difficult or even impossible.
  • Many of the symptoms and discomforts associated with Parkinson' s disease relate to the motor functions, muscle and movement control.
  • Parkinson's disease The four primary symptoms of Parkinson's disease are tremors, rigidity, bradykinesia and postural instability.
  • a tremor comprises of involuntary rhythmical trembling or shaking of the limbs, the head or the whole body.
  • the best-known symptom of Parkinson's disease is the occurrence of tremor in a finger which gradually extends over the whole arm.
  • the tremor can occur in only a part or a side of the body, particularly at the first stages of the disorder.
  • Rigidity relates to stiffness or inflexibility of limbs or joints.
  • the muscle stiffness occurring in Parkinson's often begins in the legs and the neck.
  • a majority of patients have problems with muscle stiffness.
  • the muscles are tightly contracted and, in addition to stiffness, sometimes also cause pain.
  • Bradykinesia or akinesia refer to slowness of movement or complete loss of movement. Bradykinesia is one of the classic symptoms of Parkinson's disease. Someone with Parkinson's disease will often eventually develop a forward-flexed posture and a slow, shuffling gait. People may also encounter problems initiating and continuing a movement. After a period of years akinesia can occur: the patient "freezes" during his/her movements.
  • Postural instability relates to problems with balance and coordination. People with postural instability often stand in a stooped posture with a bowed head and drooping shoulders. They often develop a forward or backward leaning posture, whereby they fall easily and sustain injury. People with a backward-flexed posture often have the tendency to involuntarily walk backwards.
  • Parkinson's disease is caused by degeneration of a specific part of the brain, the substantia nigra ("black substance" or black nuclei). With the death of brain cells in the substantia nigra the supply of dopamine to the brain declines.
  • Dopamine is necessary to enable communication between brain cells which regulate control of movement. Reduction in the dopamine level results in the symptoms of Parkinson' s disease occurring. According to the American National Parkinson foundation 80% of the dopamine-producing cells have often died off before the first motor symptoms of Parkinson's disease become manifest.
  • Parkinson's disease The course of Parkinson's disease is often progressive and debilitating. Parkinson's patients often encounter problems in performing normal activities such as standing up from a chair or walking through a room. As the disease progresses, people sometimes become wheelchair- bound or bedridden.
  • Medicines can be prescribed to suppress the tremors. These medicines can have side- effects. It is therefore important to customize the dosage of the medicines as well as possible to the patient. Reliance is often placed here on the perception of the patient. This perception is however subjective because it may depend on factors such as the mood or fatigue of the patient.
  • the present invention has for its object to provide a system which can be used to objectively determine the influence of Parkinson's on the life of a patient and to optimize the use of medicines.
  • the invention provides for this purpose a measuring system comprising a timer for generating time information, a heart rate meter for measuring a heart rate of a person and a measuring device wearable on the body of the person and comprising one or more sensors for measuring movement information relating to the body or a body part of the person. It is preferred here to attach the measuring device to a body part wherein tremors occur most often or most severely. Examples of such body parts are arms, hands or wrists.
  • the timer can for instance comprise a clock which generates a time signal, such as the time in a fixed format, such as hours-minutes-seconds, optionally supplemented with the date. It is however also possible for the timer to generate only a clock signal, such as a clock pulse signal with a known frequency.
  • the measuring device further comprises a filter unit for filtering the movement information in order to form tremor information and physical activity information.
  • the movement information comprises for instance data relating to the position, speed, acceleration, optionally in direction-dependent manner, of the body or body part on or to which the measuring device is attached. This information is filtered such that a distinction can be made between tremor information and physical activity information.
  • the tremor information here comprises for instance an indication of the severity of the tremors.
  • the physical activity information can comprise information representative of the activity of the body of the person/patient. Examples of this information are the number of steps per unit time which a person makes, cycling speed, an estimated amount of calories burned off per unit time or a speed or acceleration of the body or the respective body part.
  • the physical activity information can also comprise information relating to activities of the body determined by external factors.
  • An example hereof is the acceleration or braking of a car in which the person/patient is sitting. The braking or acceleration of the car will be visible here in the physical activity information, though not or less so in the measured heart rate.
  • the heart rate of the person/patient will on the other hand rise when an exciting film is being watched, while the physical activity information will show no or hardly any increase in activity.
  • the system according to the invention also comprises a processing unit for correlating the measured heart rate, the tremor information and the physical activity information with or by means of the time information. Through this correlation a link is established between the tremor information, heart rate and physical activity information obtained at a moment in time.
  • time information is linked to each of the measured heart rate, the obtained tremor information and physical activity information.
  • This time information is preferably identical so that it is apparent what the heart rate, tremor information and physical activity information were at a given moment in time, optionally supplemented with date information.
  • the time information can however also differ. It is thus possible that a measured heart rate corresponds to a time 23:00:45, while the measurements of the physical activity information which as seen in time are closest to this heart rate measurement are correlated with a time of 23:00:50.
  • timer generates a synchronization signal, such as a clock signal, which prompts the heart rate meter and the one or more sensors in the measuring device to perform a measurement.
  • a synchronization signal such as a clock signal
  • the time information is used here as means of correlating the heart rate measurement, the tremor information and physical activity information with each other.
  • the present invention does not preclude other options or means for correlating the physical activity information, heart rate and tremor information. Embodiments can be envisaged here which do not require a timer.
  • the processing unit is further configured to construct a data set on the basis of the heart rate, tremor information and physical activity information correlated with or by means of the time information.
  • the system further comprises a central storage unit for storing the data set.
  • the central storage unit can be embodied here as a remotely accessible memory, such as a server connected to Internet.
  • the central storage unit is preferably configured so that authorized third parties can view the data stored in the central storage unit as well as the person/patient. A doctor for instance can thus view the data and draw up or modify a plan of treatment.
  • the data set preferably comprises an indication of the time corresponding to the tremor information and/or physical activity information. It is however also possible for the data set to comprise a series of values or indications of the tremor information and/or physical activity, wherein the point in time associated with a determined value corresponds to the point in time of a previous value plus a predetermined time interval. It is thus possible for the measured heart rate and the obtained tremor information and physical activity information to be periodically stored in accordance with a predetermined time interval.
  • the measuring system can further comprise a user data input unit which is configured for input of user data, for instance by the person, wherein the processing unit is further configured to correlate the entered user data with the time and wherein the processing unit is also configured to construct the data set on the basis of the user data correlated with the time information.
  • the user data can here comprise at least one from the group consisting of data concerning use of medicines, user indication concerning tremor perception and description of physical exertion.
  • the input unit can be employed by the patient/person during for instance a period of severe tremors. The opposite can however also happen, wherein the patient/person indicates by means of the input unit that no or few tremors are occurring.
  • An output unit can also be provided, such as a buzzer or vibration unit. Such a unit can for instance be used to alert the person/patient that it is time to take medication.
  • the invention does not preclude other data not correlated with or by means of the time information being added to the data stored in the central storage unit.
  • Examples of such data are information relating to gender, age and the medicines used and dosage thereof.
  • the user data can comprise subjective information concerning the perception of the tremors.
  • a correlation can later be made between the objective data, formed by the heart rate, tremor information and physical activity information, and the subjective data entered by the patient/person.
  • the patient/person can learn from this correlation or create awareness about how the perception of discomfort relates to the objective data.
  • the user data comprise for instance whether a pushbutton provided for the purpose is pressed in or not, it is preferred that the person/patient and the doctor both understand what is meant by the pushbutton being pressed in or not.
