Abstract
Description
[Technical Field]
[0001] Field
[0002] Embodiments described herein relate to medical devices for improved subject testing and subject analysis. More specifically, embodiments described herein provide diagnostic devices, systems, and methods for assessing the severity and progression of symptoms of muscle disorders, particularly spinal muscular atrophy (SMA), in a subject through active testing of the subject. [Background technology]
[0002] background Spinal muscular atrophy (SMA), also known as proximal spinal muscular atrophy and 5q spinal muscular atrophy, is an autosomal recessive disorder that is a rare but life-threatening neuromuscular disorder associated with motor neuron loss and progressive muscle wasting.
[0003] SMA has become a health problem and a significant economic burden on the health care system. Because SMA is a clinically heterogeneous disease of the CNS, there is a need for diagnostic tools that allow reliable diagnosis and differentiation of the current disease state and symptom progression, thus supporting accurate treatment.
[0004] Several standardized methods and tests exist for measuring the severity and progression of symptoms in subjects diagnosed with SMA. These tests involve a physician measuring the subject's ability to perform physical functions. These standardized tests can provide an assessment of various symptoms, particularly lung volume, by measuring the pitch variability associated with the subject's forced vital capacity (FVC), which can help track changes in these symptoms over time. Therefore, assessing the severity and progression of symptoms using standardized methods and tests can help guide treatment and therapy options.
[0005] Currently, assessment of symptom severity and progression in subjects diagnosed with muscle disorders, particularly SMA, involves monitoring and testing subjects in a clinic every 6 to 12 months. While it would be ideal to monitor and test subjects more frequently, increasing the frequency of clinic monitoring and testing can be costly and inconvenient for subjects. Summary of the Invention

[0025] Detailed Description In the following description of various aspects, reference is made to the accompanying drawings, which form a part hereof, and which show, by way of illustration, various embodiments in which the aspects described herein may be practiced. It is to be understood that other aspects and / or embodiments may be utilized and structural and functional changes may be made without departing from the scope of the described aspects and embodiments. The aspects described herein are capable of other embodiments and of being practiced or carried out in various ways. It is also to be understood that the phraseology and terminology used herein are for purposes of description and should not be regarded as limiting. Rather, the words and terms used herein should be accorded the broadest interpretation and meaning. The use of "including" and "comprising" and variations thereof is meant to encompass the items listed thereafter and their equivalents, as well as additional items and their equivalents. The use of the terms "mounted," "connected," "coupled," "disposed," "engaged," and similar terms is meant to include both direct and indirect mounting, connecting, coupling, disposing, and engaging.
[0026] The systems, methods, and devices described herein provide diagnostics for assessing lung volume in a subject with muscle disorders, particularly SMA. In some embodiments, the diagnostics may be provided to the subject as a software application installed on a mobile device, particularly a smartphone.
[0027] In some embodiments, the diagnosis involves acquiring or receiving sensor data from one or more sensors associated with a mobile device as the subject performs activities of daily living. In some embodiments, the sensors may be in a mobile device, such as a smartphone, or a wearable sensor, such as a smartwatch. In some embodiments, sensor features related to symptoms of myopathy, particularly SMA, are extracted from the received or acquired sensor data. In some embodiments, an assessment of the severity and progression of symptoms of myopathy, particularly SMA, in the subject is determined based on the extracted sensor features.
[0028] In some embodiments, systems, methods, and devices according to the present disclosure provide a diagnosis for assessing myopathy, particularly SMA pitch variability, in a subject based on active testing of the subject. In some embodiments, the diagnosis prompts the subject to perform a diagnostic task. In some embodiments, the diagnostic task is anchored or modeled after established methods and standardized tests. In some embodiments, in response to the subject performing the diagnostic task, the diagnosis acquires or receives sensor data via one or more sensors. In some embodiments, the sensors may be in a mobile device or in a wearable sensor worn by the subject. In some embodiments, sensor features related to myopathy, particularly SMA, symptoms are extracted from the received or acquired sensor data. In some embodiments, an assessment of the severity and progression of myopathy, particularly SMA, symptoms in the subject is determined based on the extracted features of the sensor data.
[0029] Assessment of the severity and progression of symptoms of myopathies, particularly SMA, using a diagnostic according to the present disclosure correlates well with assessments based on clinical outcomes and can therefore replace clinical subject monitoring and testing. Exemplary diagnostics according to the present disclosure can be used outside of a clinic environment, thus offering advantages in cost, ease of subject monitoring, and convenience for subjects. This facilitates frequent subject monitoring and testing, particularly daily, resulting in a better understanding of disease stages and providing insights into the disease that are useful to both the clinical and research communities. Exemplary diagnostics according to the present disclosure can detect even small changes in the pitch variability of myopathies, particularly SMA, in subjects early, and can therefore be used for better disease management, including personalized treatment.
[0030] FIG. 1 is a diagram of an exemplary environment in which a diagnostic device 105 for assessing myopathy, particularly SMA lung volume, in a subject 110 may be provided. In some embodiments, the device 105 may be a smartphone, smartwatch, or other mobile computing device. The device 105 includes a display screen 160. In some embodiments, the display screen 160 may be a touchscreen. The device 105 includes at least one processor 115 and a memory 125 that stores computer instructions for a symptom monitoring application 130 that, when executed by the at least one processor 115, causes the device 105 to assess myopathy, particularly SMA lung volume. The device 105 receives a plurality of sensor data via one or more sensors associated with the device 105. In some embodiments, the one or more sensors associated with the device are at least one of sensors disposed within the device or sensors worn by the subject and configured to communicate with the device. In FIG. 1, the sensors associated with the device 105 include a first sensor 120a disposed within the device 105 and a second sensor 120b that can be worn by the subject 110. The device 105 receives a plurality of first sensor data via the first sensor 120a and a plurality of second sensor data via the second sensor 120b as the subject 110 performs an activity.
[0031] The device 105 extracts features related to myopathy, particularly the lung volume of the SMA, in the subject 110 from the received first sensor data and second sensor data. In some embodiments, the symptoms of myopathy, particularly the SMA, in the subject 110 can include symptoms indicative of the FVC of the subject 110, symptoms indicative of the lung volume of the subject 110.
[0032] In some embodiments, the sensor 120 associated with the device 105 can include a sensor associated with Bluetooth and WiFi functionality, and the sensor data can include information associated with Bluetooth and WiFi signals received by the sensor 120. In some embodiments, the device 105 extracts data from the received first and second sensor data corresponding to the density of the Bluetooth and WiFi signals received or transmitted by the device 105 or the sensor. In some embodiments, an assessment of the subject's 110 lung volume due to pitch variability can be based on the extracted Bluetooth and WiFi signal data (e.g., an assessment of the subject's sociability can be based in part on the density of the picked-up Bluetooth and WiFi signals).
[0033] The device 105 determines an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features of the received first and second sensor data. In some embodiments, the device 105 transmits the extracted features to the server 150 over the network 180. The server 150 includes at least one processor 155 and a memory 161 that stores computer instructions for a symptom assessment application 170 that, when executed by the server's processor 155, causes the processor 155 to determine an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features from the device 105 received by the server 150. In some embodiments, the symptom assessment application 170 can determine an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features of the sensor data received from the device 105 and a subject database 175 stored in the memory 160. In some embodiments, the subject database 175 can include subject data and / or clinical data. In some embodiments, subject database 175 can include clinic-based sensor-based measurements of baseline long-term pitch variation lung volume from subjects with myopathy, particularly SMA. In some embodiments, subject database 175 can be independent of server 150. In some embodiments, server 150 transmits the determined assessment of myopathy, particularly SMA, lung volume in subject 110 to device 105. In some embodiments, device 105 can output the myopathy, particularly SMA, lung volume assessment. In some embodiments, device 105 can communicate information to subject 110 based on the assessment. In some embodiments, the myopathy, particularly SMA, lung volume assessment can be communicated to a clinician, who can determine an individualized treatment for subject 110 based on the assessment.
[0034] In some embodiments, the computer instructions for the symptom monitoring application 130, when executed by the at least one processor 115, cause the device 105 to assess lung volume for myopathies, particularly SMA, in the subject 110 based on active testing of the subject 110. The device 105 prompts the subject 110 to perform one or more tasks. In some embodiments, prompting the subject to perform one or more diagnostic tasks includes prompting the subject to transcribe pre-specified statements or prompting the subject to perform one or more actions. In some embodiments, the diagnostic tasks are anchored or modeled after well-established methods and standardized tests for diagnosing and assessing myopathies, particularly SMA.
[0035] In response to subject 110 performing one or more diagnostic tasks, diagnostic device 105 receives a plurality of sensor data via one or more sensors associated with device 105. As described above, the sensors associated with device 105 may include a first sensor 120a disposed within device 105 and a second sensor 120b worn by subject 110. Device 105 receives a plurality of first sensor data via first sensor 120a and a plurality of second sensor data via second sensor 120b. In some embodiments, one or more diagnostic tasks may be associated with measuring pitch variability, particularly measuring the longest "aaah" sound.
[0036] The device 105 extracts features related to myopathy, particularly the lung volume of the SMA, in the subject 110 from the received plurality of first sensor data and the received plurality of second sensor data. Symptoms of the myopathy, particularly the SMA, in the subject 110 may include symptoms representative of the lung volume of the subject 110. In some embodiments, pitch variations of the myopathy, particularly the SMA, in the subject 110 are representative of the lung volume.
[0037] The device 105 determines an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features of the received first and second sensor data. In some embodiments, the device 105 transmits the extracted features to the server 150 over the network 180. The server 150 can include at least one processor 155 and a memory 161 that stores computer instructions for a symptom assessment application 170 that, when executed by the server's processor 155, causes the processor 155 to determine an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features from the device 105 received by the server 150. In some embodiments, the symptom assessment application 170 can determine an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features of the sensor data received from the device 105 and a subject database 175 stored in the memory 160. In some embodiments, the subject database 175 can include subject data and / or clinical data. In some embodiments, subject database 175 may include baseline long-term pitch variability measurements from subjects with myopathy, particularly SMA. In some embodiments, subject database 175 may include data from subjects with other stages of myopathy, particularly SMA. In some embodiments, subject database 175 may be independent of server 150. In some embodiments, server 150 transmits the determined assessment of myopathy, particularly SMA lung volume, in subject 110 to device 105. In some embodiments, device 105 may output the myopathy, particularly SMA lung volume assessment. In some embodiments, device 105 may communicate information to subject 110 based on the assessment. In some embodiments, the myopathy, particularly SMA lung volume assessment may be communicated to a clinician, who may determine an individualized treatment for subject 110 based on the assessment.
[0038] FIG. 2 illustrates an exemplary method for assessing myopathy, particularly SMA lung volume, in a subject based on active testing of the subject using the exemplary device 105 of FIG. 1. FIG. 3 is described with reference to FIG. 1, but it should be noted that the steps of the method of FIG. 3 may be performed by other systems. The method includes prompting the subject to perform one or more diagnostic tasks (205). The method includes receiving a plurality of sensor data via one or more sensors in response to the subject performing the one or more tasks (step 210). The method includes extracting a plurality of features associated with myopathy, particularly SMA lung volume, from the received sensor data (215). The method includes determining an assessment of myopathy, particularly SMA lung volume, based at least on the extracted sensor data (step 220).
[0039] Figure 2 illustrates an exemplary method for assessing lung volume in muscle disorders, particularly SMA, based on active testing of a subject 110 using the exemplary device 105 of Figure 1. In some embodiments, active testing of a subject 110 using the device 105 may be selected via a user interface of a symptom monitoring application 130.
[0040] The method begins by proceeding to step 205, which includes prompting the subject 110 to perform one or more diagnostic tasks. The device 105 prompts the subject 110 to perform one or more diagnostic tasks. In some embodiments, prompting the subject to perform the one or more diagnostic tasks includes prompting the subject to perform one or more movements. In some embodiments, the diagnostic tasks are anchored or modeled after well-established methods and standardized tests for diagnosing and assessing muscle disorders, particularly SMA.
[0041] In some embodiments, the diagnostic task may include making the loudest "aaah" sound possible to encourage the monster to cross the finish line.
[0042] In certain embodiments of the invention, a long or loud "aaah" sound allows the time spent by the subject blowing forcefully from full inspiration to full expiration while making the sound to be measured.
[0043] In another embodiment of the invention, the invention involves measuring the time a subject takes to forcefully breathe from full inspiration to full expiration while emitting a long or loud "aaah."
[0044] As used herein, the term "test" refers to a test in which a subject is asked to perform a diagnostic task as described herein.
[0045] The method proceeds to step 210, which includes receiving a plurality of second sensor data via one or more sensors in response to the subject 110 performing the one or more diagnostic tasks. In response to the subject 110 performing the one or more diagnostic tasks, the diagnostic device 105 receives the plurality of sensor data via one or more sensors associated with the device 105. As described above, the sensors associated with the device 105 include a first sensor 120a disposed within the device 105 and a second sensor 120b worn by the subject 110. The device 105 receives the plurality of first sensor data via the first sensor 120a and the plurality of second sensor data via the second sensor 120b.
[0046] The method proceeds to step 215 with extracting a second plurality of features from the received sensor data related to myopathy, particularly SMA lung volume. The device 105 extracts features from the received first and second sensor data related to myopathy, particularly SMA lung volume, in the subject 110. Symptoms of myopathy, particularly SMA, in the subject 110 may include symptoms representative of the lung volume of the subject 110. In some embodiments, the extracted features of the first and second plurality of sensor data may be representative of myopathy, particularly SMA, symptoms such as pitch fluctuations.
[0047] The method proceeds to step 220, which includes determining an assessment of myopathy, particularly SMA lung volume, based on at least the extracted sensor data. The device 105 determines an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features of the received first and second sensor data. In some embodiments, the device 105 can transmit the extracted features to the server 150 via the network 180. The server 150 includes at least one processor 155 and a memory 160 that stores computer instructions for a symptom assessment application 170 that, when executed by the processor 155, determines an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features from the device 105 received by the server 150. In some embodiments, the symptom assessment application 170 can determine an assessment of myopathy, particularly SMA lung volume, in the subject 110 based on the extracted features of the sensor data received from the device 105 and a subject database 175 stored in the memory 160. The subject database 175 can include various clinical data. In some embodiments, the second device may be one or more wearable sensors. In some embodiments, the second device may be any device including a motion sensor with an inertial measurement unit (IMU). In some embodiments, the second device may be several devices or sensors. In some embodiments, the subject database 175 may be independent of the server 150. In some embodiments, the server 150 transmits the determined assessment of myopathy, particularly SMA lung volume, in the subject 110 to the device 105. In some embodiments, as shown in FIG. 1 , the device 105 may output the assessment of myopathy, particularly SMA lung volume, on the display 160 of the device 105.
[0048] As described above, the assessment of symptom severity and progression of myopathies, particularly SMA, using the diagnostics disclosed herein correlates well with clinical outcome-based assessments and can therefore replace clinical subject monitoring and testing. The diagnostics disclosed herein were studied in a group of subjects with myopathies, particularly SMA subjects. Subjects were provided with a smartphone application that included a lung volume test, specifically a test called "Cheer the Monster."
[0049] FIG. 3 illustrates an example of a network architecture and data processing devices that can be used to implement one or more exemplary aspects described herein, such as those described in FIGS. 1 and 2. Various network nodes 303, 305, 307, and 309 may be interconnected via a wide area network (WAN) 301, such as the Internet. Other networks, including private intranets, corporate networks, LANs, wireless networks, and personal networks (PANs), may also or instead be used. Network 301 is illustrative and may be replaced by fewer or additional computer networks. The local area network (LAN) may have one or more of any known LAN topologies and may use one or more of a variety of protocols, such as Ethernet. Devices 303, 305, 307, 309 and other devices (not shown) may be connected to one or more of the networks via twisted pair wire, coaxial cable, optical fiber, radio waves, or other communication media.
[0050] The term "network," as used herein and depicted in the drawings, refers not only to a system in which remote storage devices are coupled together through one or more communication paths, but also to stand-alone devices that may be coupled to such a system at any time with storage capabilities. Thus, the term "network" includes not only a "physical network" but also a "content network" consisting of data—belonging to a single entity—that resides across all physical networks.
[0051] The components may include a data server 303, a web server 305, and client computers 307, 309. The data server 303 provides overall access, control, and management of the databases and control software for implementing one or more exemplary embodiments described herein. The data server 303 may be connected to a web server 305 with which users interact and obtain requested data. Alternatively, the data server 303 may itself operate as a web server and be connected directly to the Internet. The data server 303 may be connected to the web server 305 via a network 301 (e.g., the Internet) through a direct or indirect connection, or through some other network. Users may interact with the data server 303 using remote computers 307, 309, for example, by using a web browser to connect to the data server 303 through one or more publicly accessible websites hosted by the web server 305. The client computers 307, 309 may be used in conjunction with the data server 303 to access data stored therein, or may be used for other purposes. For example, from client device 307, a user may access web server 305 using an internet browser as known in the art or by executing a software application that communicates with web server 305 and / or data server 303 over a computer network (such as the internet). In some embodiments, client computer 307 may be a smartphone, smartwatch, or other mobile computing device and may implement a diagnostic device such as device 105 shown in FIG. 1. In some embodiments, data server 303 may implement a server such as server 150 shown in FIG. 1.
[0052] The servers and applications may be combined on the same physical device, maintain separate virtual or logical addresses, or may reside on separate physical devices. Figure 1 shows only one example of a network architecture that may be used, and those skilled in the art will appreciate that the particular network architecture and data processing devices used may vary and are secondary to the functionality they provide, as described further herein. For example, the services provided by web server 305 and data server 303 may be combined on a single server.
[0053] Each of the components 303, 305, 307, and 309 may be any type of known computer, server, or data processing device. The data server 303 may include, for example, a processor 311 that controls the overall operation of the rate server 303. The data server 303 may further include RAM 313, ROM 315, a network interface 317, an input / output interface 319 (e.g., a keyboard, a mouse, a display, a printer, etc.), and memory 321. The I / O 319 may include various interface units and drivers for reading, writing, displaying, and / or printing data or files. The memory 321 may further store operating system software 323 for controlling the overall operation of the data processing device 303, control logic 325 for directing the data server 303 to perform aspects described herein, and other application software 327 that provides secondary support and / or other functions that may or may not be used in combination with other aspects described herein. The control logic is sometimes referred to herein as data server software 325. The functionality of the data server software can refer to actions or decisions that are made automatically based on rules coded into the control logic, actions or decisions that are made manually by a user by providing input to the system, and / or a combination of automated processing based on user input (e.g., queries, data updates, etc.).
[0054] Additionally, memory 321 can store data used to perform one or more aspects described herein, including first database 329 and second database 331.

[0061] A test for measuring finger strength by pressure measurement was conducted on a mobile phone (iPhone). Patients were to return monsters to their nests by tapping them with their index finger. The phone was to be placed on a table. The monsters were to be tapped as quickly as possible. The patient had to select a preferred hand to use. Patients were required to play the game for 30 seconds with the goal of obtaining the maximum pressure of a single tap, the median time from monster appearance to tapping the monster, and the total number of monsters tapped within the 30-second period. The standard deviation of maximum pressure, median maximum pressure, maximum single tap pressure, median time from monster appearance to hitting the monster, and total number of monster hits obtained within the 30-second period were determined. True monster hits were protocoled events. This data was transferred, and the timestamps of the monster hits were used to calculate the median time to hit the monster.
