Summary
Normative values for the Forgotten Joint Score-12 (FJS-12) were established for the US population. These scores vary by age and sex, crucial for interpreting joint awareness in hip and knee patients.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Health Outcomes Research
Background:
- The Forgotten Joint Score-12 (FJS-12) measures joint awareness in hip and knee conditions.
- Interpreting FJS-12 scores requires established normative data for the general population.
Purpose of the Study:
- To collect normative values for the FJS-12 in the United States general population.
- To enhance the interpretability of FJS-12 outcomes for patients with hip and knee pathologies.
Main Methods:
- A sample of 2000 US adults was surveyed using an online panel.
- Quota sampling ensured representation across age and sex groups, with 200 participants per stratum.
- Raking was applied to align the sample with 2010 US census data for accurate weighting.
Main Results:
- Median FJS-12 scores were 75.0 for knees and 87.5 for hips in the overall sample.
- Significant age- and sex-specific variations were observed, with lowest knee scores in younger men (54.2) and highest in older men (97.0).
- Hip scores showed similar trends, lowest in younger men (60.9) and highest in older men (100.0).
Conclusions:
- Normative FJS-12 values for hip and knee joints have been successfully established for the US general population.
- Interpreting FJS-12 scores necessitates consideration of age- and sex-specific normative data for accurate clinical assessment.

01:07z Scores and Unusual Values

The z score is one of the three measures of relative standing. It describes the location of a value in a dataset relative to the mean. z scores are obtained after the standardization of the values in a dataset. The z score for the mean is 0.
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Nurses are responsible for caring for patients during birth, death, illness, and healing. Professional values guide the decisions and actions that nurses make in their careers. If nurses know the decisions and actions to take, providing patients with exceptional care is possible.
The values that are the foundation of the nursing profession are altruism, autonomy, human dignity, and social justice.
First, altruism refers to the concern for the welfare and well-being of others without personal...

A critical value is a definite value obtained from a particular probability distribution at a predecided confidence level (or a predecided significance level) for a given population parameter. The critical value provides demarcation that separates the sample statistics that are likely to occur from the ones that are unlikely to occur based on the given probability distribution and the population parameter to be estimated. The critical value for normal distribution is obtained from the z...

01:06Introduction to z Scores
11.2K
A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...
