Evaluation of knee range of motion by a smartphone application on schoolaged children.

Purpose: To evaluate the validity and intra-reliability of Dr. Goniometer application in measuring knee range of motion on school-aged children. Materials and Methods: 150 school-aged children, ranging in age from 12 to 16, were all free of anthropometric differences that would prevent joint range. To compare ROM measurements taken with the Dr. Goniometer a within session test-retest design was adopted. Results: The validity ROM of this investigation revealed a significant difference in knee flexion (r=0.88 and p=0.0001) and a non-significant difference in knee extension (r=-0.06 and p=0.42). Conclusion: The Dr. Goniometer app might be used in a clinical situation comparable to that of the study, allowing rehabilitation physicians and therapists to acquire precise measurements of ROM using a smartphone in daily clinical practice.
