Our aim in this study was to examine relationships between the motor activity ability, sensor-based kinematics and forward-backwards gait characteristics of children with cerebral palsy (CP). In this prospective cross-sectional study we studied 40 children with CP. We used the Pediatric Motor Activity Log Revised (PMAL-R) to assess motor activity, evaluated motion kinematics (acceleration and angular velocity) with a sensor-based application, applied the Edinburgh Visual Gait Score (EVGS) and the Timed Up and Go Test (TUG) to observe gait performance, and used the Three Meter Backward Walk Test (3MBWT) to assess backward gait. We found moderately positive significant correlations (r1 = 0.416, r2 = 0.418, p < 0.05) between the chilidren's minimum angular velocity on PMAL-R motor activity frequency (how often) and quality (how well) scores, respectively. We also found moderately negative significant correlations (r1 = −0.529, r2 = −0.521, p < 0.05) between PMAL-R frequency (how often) and quality (how well) scores with TUG, respectively. There were moderately high positive correlations (r1 = 0.415, r2 = 0.726, p < 0.05) between EVGS scores and 3MBWT and TUG scores, respectively. We concluded that angular velocity ability was moderately related to children’s motor activity and showed that physical performance tests (TUG and 3MBWT) could monitor gait function and upper extremity motor activity level, including both forward and backward walking tasks, in children with CP.

“…In addition to video analysis, velocity and acceleration in different types of motions can be measured by accelerometers, gyroscopes, magnetometers, ambient light sensors, and global positioning system (GPS) [13]. Measurement suites were also developed, enabling the multiple sensing of physical quantities [14]. Apart from those listed in Table 1, more sensors are incorporated into the latest smartphones, including pedometers, near field communication (NFC) sensors, and biometric units.…”

<span>Smartphone has gone beyond a communication hub to be a measurement device itself, thanks to various built-in sensors. This article reviewed achievements in transforming ubiquitous smartphones into cost-effective scientific instruments for educational laboratories, environmental studies, point-of-care diagnostics, home-based health monitoring, and rehabilitation. Magnetic fields were precisely measured by built-in magnetometers, leading to demonstrations for engineering and medical applications. The smartphone-based joint-angle measurement was a viable alternative to traditional goniometers. Characterizations of optical signals captured by cameras led to portable spectrophotometers and colorimeters for both educational and practical uses. Interestingly, smartphones became a platform for high-resolution microscopes and fluorescence microscopes were developed with add-on components. These smart instruments become even more attractive options in the pandemic period with limited facility and laboratory access.</span>

“…So the use of a PhyPhox-based real lab with a LabXChange-based virtual lab will produce results that are not much different. According to Pierratos [15] in his research using PhyPhox stated that the use of PhyPhox has been designed in such a way with a calibrated sensor so that it does not produce an error value that is too high. Meanwhile, virtual lab is an integrated laboratory activity instrument that has been designed in such a way and has been determined based on the value of real lab experiments [16].…”

Virtual Laboratory (virtual lab) is a series of virtual experiment laboratories that have been designed and programmed to be used by students for practicum, especially during the Covid-19 pandemic. The virtual lab is helpful for student to build content knowledge which usually they do in real practicum activities. The virtual lab is arranged systematically. Therefore, the result should be close to the real value. Here we report our study on pendulum whether the virtual lab experiment yield the same result as the real laboratory (real lab). We compare both results of experimental data using data analytics and also graphic analytics. The results from the study, shows that there is no significant difference between virtual lab and real lab. Thus, the virtual laboratory is a comparable pendulum experimental result for students doing a remote practicum in physics.
