C omputer technology is increasingly being integrated into medical care. 16 , 18 , 19 Use of handheld computers has become more common among health care providers and throughout the general population. 10 , 28 , 31 , 34 In particular, over the last decade there have been rapid developments in smartphones. These mobile phones can perform many of the functions of the most sophisticated computer devices, particularly with regard to speed, storage capacity, optical resolution, and camera functionality; 17 and their compact size makes them useful in settings that

objective patient monitoring. 7–9 There is a need for more objective, patient centered and less invasive tools to assess patients’ ability to return to activity after surgery. Recently, there has been increasing interest in the use of smartphone and wearable devices to collect this type of information. 10–13 The data generated by these devices can be used to study social, behavioral, and cognitive phenotypes in naturalistic settings. This approach, now known as digital phenotyping, has been defined as moment-by-moment quantification of the individual-level human

data, patients are generally advised to simply restrict their use in the vicinity of a PV. Universal restriction of the use of such devices may have a negative impact on patients’ quality of life. The aim of this study was to evaluate the MFs of reference devices using smartphone-integrated magnetometers and compare the results with those of published shunt tolerances to determine the potential to translate existing precautionary data to applicable values from smartphone magnetometers. Furthermore, we sought to assess the consistency of measurements across

examined. To provide better postoperative healthcare for patients with PD who received DBS surgery and to allow surgeons improved tracking of surgical outcomes, we used smartphones to perform virtual assessments. Methods Recruitment The Center for Functional Neurosurgery at Ruijin Hospital, Shanghai, has performed more than 1000 PD-related DBS surgeries over the past 20 years. Before surgery, demographic information and motor and nonmotor assessment scores were collected in the database for clinical reference and research purposes. Patients, doctors, and

physicians to understand when pain and functional decline warrant treatment and also prevents accurate quantification of postoperative functional improvement, a key objective for patients undergoing spine surgery. 16 The lack of fidelity in PROM-based assessment of preoperative functional decline emphasizes the need for measurement modalities that can quantify patient ability and disability in a more accurate and timely manner. Electronic devices that are capable of monitoring physical activity levels with relative ease, such as smartphones and smartwatches, address

resource-intensive manner by trained physiotherapy personal. New smartphone technology allows for Global Positioning System (GPS)–based determination of the 6WD using a spine-specific, free, and accurate smartphone app ( Fig. 1 ). 13 FIG. 1. Screenshot of the user interfaces of the 6WT smartphone app. A: In this example, the measurement is at 3:59 minutes and 248 meters and ongoing. Patients can push the “flash” button (lightning bolt) when they experience clinically relevant symptoms (e.g., back pain, neurogenic claudication, sciatica). The app will register the time

equipment and are associated with a high responder burden. 7 To overcome these challenges and to make objective patient evaluation more feasible, we recently developed a free smartphone app that allows patients to self-determine their walking capacity. The 6-minute walking test (6WT) accurately assesses the maximum distance (in meters) a patient can walk in 6 minutes by triangulating global positioning system (GPS) coordinates. 11 In order for the 6WT to gain broad acceptance, we need to scrutinize its psychometric properties and correlate the test to established PROMs

treatment and the shortage of cerebrovascular specialist has led to many attempts to modify how our health care system approaches stroke care. Many of these pursuits have been spurred by modern advancements in technology and communication systems. Examples include the implementation of telestroke, educating emergency medical services (EMS) personnel in localizing lesions using screening tools, and the advent of mobile stroke units (MSUs), mobile embolectomy teams, and smartphone applications that can be used by both physicians and patients to aid stroke care.
