Gait & Posture
|June 3, 2018
Summary
Smart devices accurately measure gait metrics like speed and stride length, matching inertial sensors. This technology offers a practical, valid approach for future clinical gait analysis.
Area of Science:
- Biomechanics
- Wearable technology
- Gait analysis
Background:
- Traditional gait analysis is costly and impractical for clinical use.
- Inertial sensors are increasingly used for gait analysis.
- Smart devices offer a potential alternative for gait quantification.
Purpose of the Study:
- To compare spatiotemporal gait metrics obtained from smart devices against those from validated inertial sensors.
Main Methods:
- Twenty healthy adults completed a 6-minute walk test.
- Participants wore both inertial sensors and smart devices.
- Key gait parameters including stride duration, length, cadence, and speed were recorded.
Main Results:
- Strong correlations (r>0.9) were observed for all measured gait metrics.
- Excellent agreement was found between smart device and inertial sensor measurements.
Conclusions:
- Smart devices demonstrate accuracy comparable to inertial sensors for gait analysis.
- This technology holds promise for ecologically valid gait assessments in clinical populations.

01:03Inertial Frames of Reference
8.8K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

01:27Non-inertial Frames of Reference
7.2K
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

01:10Wave Parameters
9.4K
The simplest mechanical waves are associated with simple harmonic motion and repeat themselves for several cycles. These simple harmonic waves can be modeled using a combination of sine and cosine functions. Consider a simplified surface water wave that moves across the water's surface. Unlike complex ocean waves, in surface water waves, water moves vertically, oscillating up and down, whereas the disturbance of the wave moves horizontally through the medium. If a seagull is floating on the...

01:26Distributions to Estimate Population Parameter
5.2K
The accurate values of population parameters such as population proportion, population mean, and population standard deviation (or variance) are usually unknown. These are fixed values that can only be estimated from the data collected from the samples. The estimates of each of these parameters are sample proportion, the sample mean, and sample standard deviation (or variance). To obtain the values of these sample statistics, data are required that have particular distribution and central...

01:01Dosage Regimens: Partial Pharmacokinetic Parameters
180
It is not uncommon for complete drug pharmacokinetic profiles to remain elusive in pharmacokinetics. This necessitates certain educated assumptions by pharmacokineticists to determine appropriate dosage regimens without comprehensive pharmacokinetic data from animal or human studies. One prevalent assumption is setting the bioavailability factor, denoted as F, to 1 or 100%. This assumption caters to the scenario where a drug doesn't achieve full systemic absorption, resulting in the patient...

00:54Noncompartmental Analysis: Miscellaneous Pharmacokinetic Parameters
460
The noncompartmental approach is a widely used method in pharmacokinetics to assess drugs' behaviors in the body. It considers several factors, including clearance, bioavailability, and total volume of distribution.
One key aspect of the noncompartmental approach is determining a drug's total clearance. This can be done by dividing the drug dose by the area under the concentration-time curve from zero to infinity. The area under the concentration-time curve represents the drug's...
