Resumo

Purpose: Shoulder range of motion measurement is not only of diagnostic significance but is also relevant for monitoring response to therapeutic interventions. Smartphones incorporate accelerometers which enable easy multiaxial and multiangle measurements but their reliability compared to the classic goniometer remains to be established. The authors aim to ascertain the intra-rater reliability between manual and smartphone-based digital goniometry in measuring active flexion (AF) and external rotation (ER) in both standing (St) and supine (Su) positions.

 

Methods: A convenience sample of 16 healthy volunteers was selected. Measures were taken by an independent rater at two different times, a week apart. We randomized both participant’s order and measurement sequence. The rater was trained according to a predetermined measurement protocol and blinded to intermediate measurements. We evaluated agreement between methods using the intraclass correlation coefficient (ICC), visual inspection of Bland-Altman plots and calculation of the limits of agreement.

 

Results: The intra-rater correlation was good regarding the ER-StICC 0,87 (IC 95%: 0,66-0,95), the ER-SuICC 0,92 (IC 95%: 0,80-0,97)) and the AF-StICC 0,92 (IC 95%: 0,78-0,97). The score was lower in the AF-SuICC 0,81 (IC 95%: 0,55-0,93).

 

Conclusions: There was a good intra-rater reliability between classic and digital goniometer in ER (regardless of positioning) and in standing AF. The smartphone based digital goniometer might be an easy tool to assist physical examination in healthy individuals, but its accuracy and applicability to clinical settings needs further evaluation.
