Background: A simple method for measuring arm mass in clinical practice would be useful for medical records and experimental approaches; however, which but there is no popular measurement method.
Objective: To develop a simple, accurate, and reliable method for approximating arm masses.
Methods: A theoretical model for estimating the mass of the lower and upper arms was proposed. The validity of the model was confirmed via 34 measurements on a steel model in each of the nine upper arm abduction positions using one-sample t-tests. The reproducibility of the method was investigated by performing repeat measurements for 29 participants and was confirmed using paired t-tests.
Results: One-sample t-tests showed no significant differences (p < 0.05) in the mean of the nine upper arm abduction positions investigated during the model validation. Regarding reproducibility, the paired t-tests showed no significant differences (p < 0.05), and the 95% confidence intervals were corroborated by previous reports. Interpretation of intraclass correlation (ICC) was difficult because of inappropriate application.
Limitations: The reproducibility of the suggested method should be verified using an appropriate statistical method.
Conclusions: Because of insufficient reproducibility, supplemental method is required, such as the adjusted backrest fitting better for all subject, and assessor must try to achieve reproducibility when the therapists use this method in clinical practice.
