Shoulder Strength Changes One Year After Axillary Lymph Node Dissection or Sentinel Lymph Node Biopsy in Patients With Breast Cancer.

Objectives: To assess the changes in shoulder strength of patients with breast cancer during the first year after surgery; and to compare the effect of sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND) on shoulder strength.

Design: Prospective longitudinal observational study from presurgery to 1 year after.

Setting: Tertiary hospital.

Long thoracic nerve injury in breast cancer patients treated with axillary lymph node dissection.

Purpose: The objectives of this study were to electromyographically (EMG) describe and analyze factors associated with long thoracic nerve injuries in breast cancer patients after axillary lymph node dissection.

Methods: This was a prospective longitudinal observational study. Two hundred sixty-four women with primary invasive breast cancer were included between 2008 and 2011.

Lymphedema Predictor Factors after Breast Cancer Surgery: A Survival Analysis.

Background: Factors associated with lymphedema development after breast cancer surgery are not well established. The purpose is to assess the value of patient, disease and treatment-related factors predicting lymphedema development.

Methods And Results: This study included 371 women with primary invasive breast cancer treated surgically between 2005 and 2009 with follow-up until December 2011.

Balance 1 year after TKA: correlation with clinical variables.

Knee osteoarthritis results in changes that affect balance. It has been reported that osteoarthritis worsens proprioception and increases the risk of falling. The objective of this study was to assess changes in balance among patients with knee osteoarthritis at 1 year after total knee arthroplasty (TKA) surgery and its relationship with clinical variables.
