Summary
Smartphone video examinations (VE) provide a reliable method for assessing shoulder function. This study found VE results closely matched traditional face-to-face (FTF) assessments, offering a convenient alternative.
Area of Science:
- Orthopedics
- Telemedicine
- Digital Health
Background:
- Video examinations (VE) offer accessible, low-cost physician consultations, reducing travel and wait times.
- Smartphone-based VE presents a potential solution for remote patient assessment.
Purpose of the Study:
- To validate the use of smartphones for remote assessment of shoulder function.
- To compare Constant Scores (CS) from VE with conventional face-to-face (FTF) examinations.
Main Methods:
- Prospective study of 51 patients (19-80 years) at a shoulder clinic.
- Patients underwent both FTF and VE assessments in alternating order.
- Comparison of Constant Scores (CS) obtained via both methods.
Main Results:
- 92% of subjects (47/51) successfully completed both examinations.
- Mean difference in CS between VE and FTF was -0.53 points (95% CI: -2.6 to 1.6).
- High agreement (correlation coefficient 0.91, accuracy 0.99, precision 0.91) between VE and FTF CS.
Conclusions:
- Smartphone-based VE reliably estimates shoulder function.
- VE provides a comparable assessment to FTF examinations, with minimal deviation in scores.

01:29Reliability 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.

01:23Muscles of the Shoulder
9.1K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

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...

97.6K
Calorimetry is a technique used to measure the amount of heat involved in a chemical or physical process or to measure the heat transferred to or from a substance. The heat is exchanged with a calibrated and insulated device called the calorimeter. Calorimetry experiments are based on the assumption that there is no heat exchange between the insulated calorimeter and the external environment. The well-insulated calorimeters prevent the transfer of heat between the calorimeter and its external...
