Background. A recent study in our laboratory found signifi cant differences in scapular kinematics between the affected and unaffected sides of women reporting shoulder pain following treatment for breast cancer. An earlier smaller study from our laboratory found reduced muscle activity from four key muscles and an association with greater shoulder pain and disability. The aims of this study were to: correlate altered muscle activity from a larger sample with observed movement deviations; compare within subject movement and muscle deviations in survivors with healthy variation; explore the impact of a mastectomy vs. a wide local excision (WLE) on the observed deviations. Method. Cross-sectional study. One hundred and fi fty-fi ve women treated for unilateral carcinoma of the breast and 21 age-matched healthy women were included in the study. All patients fi lled out the Shoulder Pain and Disability Index (SPADI). Three-dimensional (3D)-kinematic data and EMG muscle activity were recorded during scaption on the affected and unaffected side. The association between kinematic data, EMG data, SPADI and covariates was determined using a two stage, random effects mixed multiple regression technique. Results. All scapula kinematic and muscle EMG parameters in both arms were altered in breast cancer survivors when compared to healthy participants. Altered movement patterns were different for left vs. right side affected. Mastectomy patients demonstrated greater movement deviations and reported signifi cantly higher levels of pain than WLE patients. Conclusion. Shoulder morbidity is bilateral, greater in patients having a mastectomy and is present for up to six years post-surgery. This study and others now provide ample evidence to support prospective surveillance programmes that can be integrated into Survivorship Programmes.

Varying levels of shoulder morbidity following treatment for breast cancer have been reported. Patients report pain, weakness, tightness and reduced functional capacity. Normal painfree motion of the arm and shoulder requires mobility in the scapulothoracic, glenohumeral, acromioclavicular and sternoclavicular joints. Under healthy conditions elevation of the arm is accompanied by scapula retraction, lateral rotation and posterior tilt. However, when scapulothoracic motion is disproportionate to glenohumeral motion, the potential exists for microtrauma and long term pain. A number of studies on women treated for breast cancer have shown limitations in glenohumeral range of movement and a recent report from our laboratory has shown decreased muscle activity in four key muscles acting on the scapula. However, no study has measured the effect of treatment on three-dimensional (3-D) scapulothoracic motion in relation to glenohumeral motion. 152 women treated for unilateral carcinoma of the breast were included in the study. All patients filled out the Shoulder Pain and Disability Index (SPADI). 3-D-kinematic data for the humerus and scapula was recorded during scaption on the affected and unaffected side. The association between kinematic data, SPADI and covariates was determined using random effects multiple regression techniques. All scapula kinematic parameters were significantly altered on the side of the carcinoma in breast cancer survivors. Both reported levels of pain and dysfunction were associated with altered kinematics. High levels of pain and disability were reported for up to 6 years post surgery. Patients with the left side affected reported higher levels of pain and demonstrated more significant scapulathoracic dysfunction independent of dominance. Altered movement patterns were different for left versus right side affected. Left side affected patients need to be considered as a group of patients at risk of experiencing higher levels of pain and showing greater shoulder dysfunction. Whether cause or effect, pain reports are accompanied by 3-dimensional scapula dysfunction which mimics that of many other shoulder conditions.

Physiotherapy is considered an important component of the perioperative period of lung resection surgery. A systematic review was conducted to assess evidence for the effectiveness of different physiotherapy interventions in patients undergoing lung cancer resection surgery. Online literature databases [Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, SCOPUS, PEDro and CINAHL] were searched up until June 2013. Studies were included if they were randomized controlled trials, compared 2 or more perioperative physiotherapy interventions or compared one intervention with no intervention, included only patients undergoing pulmonary resection for lung cancer and assessed at least 2 or more of the following variables: functional capacity parameters, postoperative pulmonary complications or length of hospital stay. Reviews and meta-analyses were excluded. Eight studies were selected for inclusion in this review. They included a total of 599 patients. Seven of the studies were identified as having a low risk of bias. Two studies assessed preoperative interventions, 4 postoperative interventions and the remaining 2 investigated the efficacy of interventions that were started preoperatively and then continued after surgery. The substantial heterogeneity in the interventions across the studies meant that it was not possible to conduct a meta-analysis. The most important finding of this systematic review is that presurgical interventions based on moderate-intense aerobic exercise in patients undergoing lung resection for lung cancer improve functional capacity and reduce postoperative morbidity, whereas interventions performed only during the postoperative period do not seem to reduce postoperative pulmonary complications or length of hospital stay. Nevertheless, no firm conclusions can be drawn because of the heterogeneity of the studies included. Further research into the efficacy and effectiveness of perioperative respiratory physiotherapy in this patient population is needed.
