RESUMO
PURPOSE: Consumer-based activity trackers are used to measure and promote PA. We studied the accuracy of a wrist- and waist-worn activity tracker in cancer survivors and compared these results to a healthy age-matched control group. METHODS: Twenty-two cancer survivors and 35 healthy subjects wore an activity tracker at the waist and at the wrist combined with a reference activity monitor at the waist (Dynaport Movemonitor). The devices were worn for 14 consecutive days. The mean daily step count from both activity trackers was compared with the reference activity monitor to investigate accuracy and agreement (paired t-test, intraclass correlation, Bland-Altman plots). To evaluate the accuracy as a coaching tool, day-by-day differences within patients were calculated. The Kendall correlation coefficient was used to test the consistency of ranking daily steps between the activity trackers and the reference activity monitor. RESULTS: The wrist-worn wearable significantly overestimated the daily step count in the cancer group (mean ± SDΔ: + 1305 (2685) steps per day; p = 0.033) and in the healthy control group (mean ± SDΔ: + 1598 (2927) steps per day; p = 0.003). The waist-worn wearable underestimated the step count in both groups, although this was not statistically significant. As a coaching device, moderate (r = 0.642-0.670) and strong (r = 0.733-0.738) accuracy was found for the wrist- and waist-worn tracker, respectively, for detecting day-by-day variability in both populations. CONCLUSION: Our results show that wrist-worn activity trackers significantly overestimate daily step count in both cancer survivors and healthy control subjects. Based on the accuracy, in particular, the waist-worn activity tracker could possibly be used as a coaching tool.

INTRODUCTION: Secondary upper limb dysfunctions are common after breast cancer treatment. Myofascial treatment may be a valuable physical therapy modality for this problem. OBJECTIVE: To investigate the effect of myofascial therapy in addition to physical therapy on shoulder, trunk, and elbow movement patterns in women with pain and myofascial dysfunctions at the upper limb after breast cancer surgery. DESIGN: A double-blinded randomized controlled trial. SETTING: Rehabilitation unit of a university hospital. PARTICIPANTS: Forty-eight women with persistent pain after finishing breast cancer treatment. INTERVENTIONS: Over 3 months, all participants received a standard physical therapy program. The experimental (n = 24) and control group (n = 24) received 12 additional sessions of myofascial therapy or placebo therapy, respectively. MAIN OUTCOME MEASURES: Outcomes of interest were movement patterns of the humerothoracic joint, scapulothoracic joint, trunk, and elbow, measured with an optoelectronic measurement system during the performance of a forward flexion and scaption task. Statistical parametric mapping (SPM) analyses were used for assessing the effect of treatment on movement patterns between both groups (group × time interaction effect). RESULTS: A significantly decreased protraction and anterior tilting was found after experimental treatment. No beneficial effects on movement patterns of the humerothoracic joint, trunk, or elbow were found. CONCLUSION: Myofascial therapy in addition to a 12-week standard physical therapy program can decrease scapular protraction and anterior tilting (scapulothoracic joint) during arm movements. Given the exploratory nature of these secondary analyses, the clinical relevance of these results needs to be investigated further.

OBJECTIVE: The purpose of this study was to investigate the effectiveness of fluoroscopy-guided manual lymph drainage (MLD) versus that of traditional and placebo MLD, when added to decongestive lymphatic therapy (DLT) for the treatment of breast cancer-related lymphedema (BCRL) (EFforT-BCRL trial), on the suprafascial accumulation of lymphatic fluid and skin elasticity. METHODS: In this multicenter, 3-arm, double-blind, randomized controlled trial (EFforT-BCRL trial), 194 participants (mean age = 61 [SD = 10] years) with unilateral BCRL were recruited. All participants received standardized DLT (education, skin care, compression therapy, exercises) and were randomized to fluoroscopy-guided, traditional, or placebo MLD. Participants received 60 min/d of treatment during the 3-week intensive phase and 18 sessions of 30 minutes during the 6-month maintenance phase. During this phase, participants were instructed to wear a compression garment, to perform exercises, and to perform a self-MLD procedure once daily. This study comprises secondary analyses of the EFforT-BCRL trial. Outcomes were the amount of fluid accumulation in the suprafascial tissues (local tissue water, extracellular fluid, and thickness of the skin and subcutaneous tissue) and skin elasticity at the level of the arm and trunk. Measurements were performed at baseline; after intensive treatment; after 1, 3, and 6 months of maintenance treatment; and after 6 months of follow-up. RESULTS: At the level of the arm, there was a significant improvement over time in the 3 groups for most of the outcomes. At the level of the trunk, no remarkable improvement was noted within the individual groups. No significant interaction effects (between-group differences) were present. Only skin elasticity at the level of the arm, evaluated through palpation, showed a significant interaction effect. CONCLUSION: All 3 groups showed similar improvements in response to DLT regardless of the type of MLD that was added. The effect of the addition of MLD to other components of DLT for reducing local tissue water and extracellular fluid or skin thickness and for improving skin elasticity and fibrosis in participants with chronic BCRL was limited. IMPACT: Although MLD has been applied all over the world for many years, evidence regarding its added value in reducing arm volume in patients with BCRL is lacking. These results show that adding MLD to other components of DLT has limited value in reducing local tissue water and extracellular fluid or skin thickness and in improving skin elasticity and fibrosis in patients with chronic BCRL. To date, there is no clinical indication to continue including time-consuming MLD in physical therapist sessions for patients with chronic BCRL.

BACKGROUND AND OBJECTIVE: Total mesorectal excision (TME) for rectal cancer (RC) often results in significant bowel symptoms, commonly known as low anterior resection syndrome (LARS). Although pelvic floor muscle training (PFMT) is recommended in noncancer populations for treating bowel symptoms, this has been scarcely investigated in RC patients. The objective was to investigate PFMT effectiveness on LARS in patients after TME for RC. METHODS: A multicenter, single-blind prospective randomized controlled trial comparing PFMT (intervention; n=50) versus no PFMT (control; n=54) 1 month following TME/stoma closure was performed. The primary endpoint was the proportion of participants with an improvement in the LARS category at 4 months. Secondary outcomes were: continuous LARS scores, ColoRectal Functioning Outcome scores, Numeric Rating Scale scores, stool diary items, and Short Form 12 scores; all assessed at 1, 4, 6, and 12 months. RESULTS: The proportion of participants with an improvement in LARS category was statistically higher after PFMT compared with controls at 4 months (38.3% vs 19.6%; P =0.0415) and 6 months (47.8% vs 21.3%; P =0.0091), but no longer at 12 months (40.0% vs 34.9%; P =0.3897). Following secondary outcomes were significantly lower at 4 months: LARS scores (continuous, P =0.0496), ColoRectal Functioning Outcome scores ( P =0.0369) and frequency of bowel movements ( P =0.0277), solid stool leakage (day, P =0.0241; night, P =0.0496) and the number of clusters ( P =0.0369), derived from the stool diary. No significant differences were found for the Numeric Rating Scale/quality of life scores. CONCLUSIONS: PFMT for bowel symptoms after TME resulted in lower proportions and faster recovery of bowel symptoms up to 6 months after surgery/stoma closure, justifying PFMT as an early, first-line treatment option for bowel symptoms after RC.

BACKGROUND: A total mesorectal excision for rectal cancer-although nerve- and sphincter-sparing-can give rise to significant bowel symptoms, commonly referred to as low anterior resection syndrome (LARS). The exact pathophysiology of this syndrome still remains largely unknown, and the impact of radical surgery on colonic motility has only been scarcely investigated. METHODS: High-resolution colon manometry was performed in patients, 12-24 months after restoration of transit. Patients were divided into two groups: patients with major LARS and no/minor LARS, according to the LARS-score. Colonic motor patterns were compared, and the relationship of these patterns with the LARS-scores was investigated. KEY RESULTS: Data were analyzed in 18 patients (9 no/minor LARS, 9 major LARS). Cyclic short antegrade motor patterns did occur more in patients with major LARS (total: p = 0.022; post-bisacodyl: p = 0.004) and were strongly correlated to LARS-scores after administering bisacodyl (p < 0.001). High amplitude propagating contractions (HAPC's) that started in the proximal colon and ended in the mid-section of the colon occurred significantly less in patients with major LARS compared with patients with no/minor LARS (p = 0.015). CONCLUSIONS AND INFERENCES: The occurrence of more cyclic short antegrade motor patterns and less HAPC's (from the proximal to the mid-colon) is more prevalent in patients with major LARS. These findings help to understand the differences in pathophysiology in patients developing major versus no/minor bowel complaints after TME for rectal cancer.

PURPOSE: We hypothesize that prediagnosis physical activity (PA) levels of breast cancer patients are below those of a reference population without breast cancer. Therefore, the aim of the present study was to compare prediagnosis PA levels (including total-, occupational-, sport- and household activity levels) of breast cancer patients with activity levels of a reference population. METHODS: Female patients with primary breast cancer (n = 265) filled in the Flemish Physical Activity Computerized Questionnaire (FPACQ) the day before surgery recalling the year before diagnosis. PA levels were expressed as Metabolic Equivalent Task (MET) values. Smooth reference curves of PA levels were estimated in a representative sample of 3466 women without breast cancer with the LMS method, which allowed comparison of prediagnosis PA data of the breast cancer sample with this reference. RESULTS: Compared to women without breast cancer, total PA levels were significantly lower in the year prior to breast cancer diagnosis over all age groups (Mean ± SD z-scores (95% CI) = -1.51 ± 1.86 (-1.74 to -1.29)). More specifically, household PA levels of breast cancer patients were significantly lower between ages 40-60, while occupational PA levels were significantly higher in this age group. No differences were found between sports PA levels. CONCLUSIONS: Patients with breast cancer show significantly lower total PA levels during the year prior to surgery compared to a reference population. Especially household activity levels are lower in patients between ages 40 and 60. Given this, a return to prediagnosis PA levels may not be sufficient for protection from disease in the future.

AIM: The aim of the study was to investigate whether bowel symptoms related to low anterior resection for rectal cancer can be sufficiently well evaluated by the Low Anterior Resection Syndrome (LARS) questionnaire score or the ColoRectal Functional Outcome (COREFO) questionnaire compared with a stool diary. METHOD: All patients underwent low anterior resection for rectal cancer. They were asked to fill out a stool diary, the LARS questionnaire and the COREFO questionnaire, at 1, 4, 6 and 12 months after low anterior resection or stoma closure. The main outcome measure was the amount of association (calculated by means of canonical correlation analysis) between items on anal incontinence for faeces, frequency of bowel movements, clustering of bowel movements, urgency and soiling. RESULTS: Ninety-five patients were included. Items on anal incontinence for faeces and frequency of bowel movements were significantly correlated between the LARS questionnaire or the COREFO questionnaire, versus the stool diary, respectively. Items on soiling were significantly correlated between the COREFO questionnaire and the stool diary. CONCLUSION: Although the LARS questionnaire and the COREFO questionnaire are reliable and valid for measuring low anterior resection syndrome after rectal cancer, our results show that there are no strong associations with the stool diary. Therefore, we can conclude that there is additional clinical information to be obtained from the stool diary. In order to evaluate all aspects of low anterior resection syndrome, we suggest the addition of a stool diary or a combination of different measurement methods during patient follow-up.

BACKGROUND: Overall survival rates after rectal cancer have increased. Therefore, functional outcomes rightly deserve more interest. The aims of this study were to assess progression in total, sports, occupational and household physical activity levels of rectal cancer survivors, from preoperatively to 12 months after surgery/stoma closure and to explore predictive factors. METHODS: Multi-center prospective study with 125 patients who underwent low anterior resection for rectal cancer. The Flemish Physical Activity Computerized Questionnaire was completed concerning all physical activity levels at baseline (past preoperative year) and at 1, 4, 6 and 12 months after surgery/stoma closure. At these timepoints, questionnaires (LARS-/ COREFO-questionnaire) regarding bowel symptoms were also filled out. Results were analyzed using linear mixed models for repeated measures. RESULTS: Total physical activity levels up to 12 months remained significantly lower than preoperative. Occupational and sports physical activity levels remained significantly lower until 6 and 4 months postoperative, respectively. Predictive factors for decreased physical activity levels at a specific timepoint were: younger age and no stoma (total physical activity, 1 month), low/mid rectal tumor, no stoma, non-employed status (total, 4 months), higher COREFO-scores (occupational, 4 months) and non-employed status (total, 12 months). At all timepoints, lower COREFO-scores were associated with higher total physical activity levels; male gender and lower educational levels with higher occupational levels; younger age, normal BMI, employed status and adjuvant therapy with higher sports levels; and female gender, lower educational level and unemployed status with higher household levels. CONCLUSIONS: One year after rectal cancer treatment, total physical activity levels were still not recovered. Rectal cancer patients, especially those at risk for decreased physical activity levels and with major bowel complaints, should be identified and guided to increase their activities. TRIAL REGISTRATION: This trial has been registered at Netherlands Trial Register ( NTR6383 , 23/01/2017).

OBJECTIVE: To synthesize the evidence on the effectiveness of pain science education on pain, psychological factors and physical functioning in adults who underwent surgery. DATA SOURCES: A systematic literature search of English articles using PubMed/Medline, Embase, Web of Science Core Collection, and Cochrane Library. REVIEW METHODS: The search strategy was constructed as follows: (((pain) AND (education)) OR (pain education)) AND (surgery). Only controlled quantitative studies in adults reporting outcome(s) on pain, psychological factors and/or physical functioning were included. Risk of bias was assessed using the Cochrane risk of bias tools. P-values and corresponding effect sizes for interaction-effect (time × group) portrayed the difference in change over time between groups were of interest. The last search was conducted on February 28, 2021. RESULTS: Nine papers (n = 1078) were deemed eligible for this review. Two randomized controlled trials showed significant interaction effects. Breast cancer patients who had received one preoperative pain science education session showed a significant increase in postoperative pain compared to controls (P-value = 0.0394). Furthermore, psychological factors (pain catastrophizing and kinesiophobia) decreased in participants who had received pain science education before total knee arthroplasty, while this was not the case in the control group (P-value < 0.001, Æ2p:0.11). CONCLUSIONS: Overall, pain science education did not result in any significant postoperative effects on pain, psychological factors and/or physical functioning compared to controls. There is currently no strong evidence for the implementation of pain science education in the perioperative period.Registration number: PROSPERO: ID 161267, registration number CRD42020161267.

INTRODUCTION: Radical surgery after a total mesorectal excision (TME) for rectal cancer often results in a significant decrease in the patient's quality of life, due to functional problems such as bowel, urinary and sexual dysfunction. The effect of pelvic floor muscle training (PFMT) on these symptoms has been scarcely investigated. We hypothesise that the proportion of successful patients will be significantly higher in the intervention group, receiving 12 weeks of PFMT, compared with the control group without treatment. The primary outcome of this trial is the severity of bowel symptoms, measured through the Low Anterior Resection Syndrome questionnaire, 4 months after TME or stoma closure. Secondary outcomes are related to other bowel and urinary symptoms, sexual function, physical activity and quality of life. METHODS AND ANALYSIS: This research protocol describes a multicentre single blind prospective, randomised controlled trial. Since January 2017, patients treated for rectal cancer (n=120) are recruited after TME in three Belgian centres. One month following surgery or, in case of a temporary ileostomy, 1 month after stoma closure, patients are randomly assigned to the intervention group (n=60) or to the control group (n=60). The assessments concern the preoperative period and 1, 4, 6, 12 and 24 months postoperatively. ETHICS AND DISSEMINATION: The study will be conducted in accordance with the Declaration of Helsinki. Ethics approval was granted by the local Ethical Committee of the University Hospitals Leuven (s59761) and positive advice from the others centres has been obtained. Dissemination of the results will be accomplished via guidelines and (non-)scientific literature for professionals as well as organisation of patient symposia. TRIAL REGISTRATION NUMBER: NTR6383.
