Patients with Subacromial Pain Syndrome Present no Reduction of Shoulder Proprioception: A Matched Case-Control Study.

Background: Shoulder pain is common among patients with musculoskeletal pain and the prevalence of patients with subacromial pain syndrome (SAPS) is high. Despite the high prevalence, there is a lack of an extensive evaluation of the proprioception acuity in patients with SAPS. Knowledge of the proprioceptive deficit would assist clinicians in the proper treatment and may offer an alternative explanation for the mechanisms underlying SAPS, which are poorly understood.

Comparison of two proposed guidelines for aerobic training sessions.

The purpose was to compare 24 participants' acute physiological and affective responses to two aerobic prescriptions in three sessions. Anthropometry, International Physical Activity Questionnaire, and VO2max were recorded. In subsequent visits two aerobic prescriptions were randomly applied: one based on VO2max (PBVO2max) and another based on physical activity level (PBPA).
