Quantitative Analysis01:12

Quantitative Analysis

1.6K
Quantitative analysis is a technique for measuring the amount of specific constituents in a sample. When the sample's composition is unknown, qualitative analysis is performed first to identify its components, which ensures that the correct substances are measured during the quantitative phase.
In quantitative analysis, two key measurements are made: the sample quantity and a property proportional to the amount of the analyte (the substance being analyzed). This forms the basis of the...

Wald-Wolfowitz Runs Test I01:17

Wald-Wolfowitz Runs Test I

982
The Wald-Wolfowitz test, also known as the runs test, is a nonparametric statistical test used to assess the randomness of a sequence of two different types of elements (e.g., positive/negative values, successes/failures). It examines whether the order of the elements in a sequence is random or if there is a pattern or trend present. This nonparametric test applies to any ordered data despite the population and sample data distribution, even if a higher sample size is available.
The test works...

Quantifying Work

24.6K
As a system undergoes a change, its internal energy can change, and energy can be transferred from the system to the surroundings, or from the surroundings to the system.

Base Quantities and Derived Quantities01:14

Base Quantities and Derived Quantities

27.0K
In any system of units, the units for some physical quantities must be specified through a measurement process. These measurements are the base quantities of the system, and their units are the base units of the system. The algebraic combinations of the base values can then be used to express all other physical quantities. Each of these physical quantities is then referred to as a derived quantity, with each unit being referred to as a derived unit.

Kendall's Coefficient of Concordance01:20

Kendall's Coefficient of Concordance

1.1K
Kendall's Coefficient of Concordance (W), also known as Kendall's W, is a non-parametric statistical measure used to assess the agreement or concordance between multiple raters or judges when they rank a set of items. It is often used when you have ordinal data (ranks) and you want to see if there is consistency or consensus among the raters. It is widely applied in research areas such as psychology, medicine, and social sciences, where multiple judges are asked to rank or rate subjects...

Measures of Central Tendency02:16

Measures of Central Tendency

22.1K
The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...

    Area of Science:

    • Rehabilitation Engineering
    • Assistive Technology
    • Biomedical Engineering

    Background:

    • Neuromuscular disabilities often impair upper extremity function, limiting daily activities.
    • The Wilmington Robotic EXoskeleton (WREX) is a passive anti-gravity orthosis designed to aid arm movement in three dimensions.
    • Evaluating the real-world benefits and user experience of assistive devices is crucial for their adoption and effectiveness.

    Purpose of the Study:

    • To assess the functional benefits and user satisfaction of the Wilmington Robotic EXoskeleton (WREX).
    • To quantify improvements in upper extremity performance and satisfaction for individuals using the WREX.
    • To gather subjective user impressions regarding the WREX device.

    Main Methods:

    • Two surveys were conducted: an online user survey with 55 patients and a phone interview survey using the Canadian Occupational Performance Measure (COPM) with 25 families.
    • The online survey included 10 questions on upper extremity function with and without the WREX and subjective device impressions.
    • The COPM survey assessed changes in performance and satisfaction scores for daily activities with and without the WREX.

    Main Results:

    • Twenty-four out of 25 families reported increased performance and satisfaction when their child used the WREX.
    • A statistically significant improvement in arm function for everyday tasks was observed with WREX use.
    • Mean performance score increased by 3.61 points and mean satisfaction score by 4.44 points.

    Conclusions:

    • The WREX demonstrates significant efficacy in enhancing upper extremity function and user satisfaction for individuals with neuromuscular disabilities.
    • The device facilitates improved performance in daily activities, empowering users with greater independence.
    • The findings support the WREX as a valuable assistive tool for improving quality of life.
