Assessing the ability of the Fitbit Charge 2 to accurately predict VO.

Background: The aim of this study was to assess the ability of the Fitbit Charge 2 (FBC2) to accurately estimate VO in comparison to both the gold standard VO test and a non-exercise VO prediction equation.

Methods: Thirty healthy subjects (17 men, 13 women) between the ages of 18 and 35 (age =21.7±3.

Shoulder joint position sense after thermal, open, and arthroscopic capsulorrhaphy for recurrent anterior instability.

Identifying the optimal surgical treatment for recurrent, anterior glenohumeral instability remains a challenge. Our purpose was to compare shoulder joint position sense among open, arthroscopic, and thermal capsulorrhaphy patients after repair of recurrent anterior instability and to compare these patients to healthy, control subjects. Sixty-seven adults (45 post-surgical patients, 22 controls) volunteered to participate in the study.
