Reliability and Validity01:29

Reliability and Validity

13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

6.8K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

3.7K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

4.0K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Area of Science:

  • Biomedical Engineering
  • Rehabilitation Technology
  • Digital Health

Background:

  • Mobile health (mHealth) apps are increasingly popular for clinical assessment.
  • Verification and validation of mHealth apps are crucial for safe and effective use.
  • Smartphone goniometric apps offer a novel approach to joint angle measurement.

Purpose of the Study:

  • To review the literature on validated smartphone goniometric apps for joint angle measurement.
  • To assess the psychometric characteristics of these validated apps.
  • To evaluate the commercial availability and durability of selected apps.

Main Methods:

  • Conducted a literature search of Medline and Scopus databases.
  • Selected papers on validated smartphone goniometric apps relevant to Physical Medicine and Rehabilitation.
  • Performed a platform search to verify app availability and excluded unavailable apps.

Main Results:

  • Identified 23 validated smartphone goniometric apps from 49 selected papers.
  • Eight of the 23 apps were no longer commercially available.
  • Selected apps demonstrated robust psychometric characteristics, but study heterogeneity prevented direct comparison.

Conclusions:

  • Growing interest in smartphone goniometric apps for body angle measurement is evident.
  • Commercial availability of validated apps is precarious, impacting research utility.
  • Further validation studies are needed for available apps, particularly for gait and therapeutic exercises in neurological and orthopedic conditions.
