Aim Common problems after rectal resection are loose stools, faecal incontinence, increased frequency and evacuation difficulties, for which there are various therapeutic options. A systematic review was conducted to assess the outcome of treatment options aimed to improve anorectal function after rectal surgery. Method Publications including a therapeutic approach to improve anorectal function after rectal surgery were searched using the following databases: MEDLINE, PubMed, EMBASE, Pedro, CINAHL, Web of Science, PsychInfo and the Cochrane Library. The focus was on outcome parameters of symptomatic improvement of faecal incontinence, evaluation of defaecation and quality of life. Results The degree of agreement on eligibility and methodological quality between reviewers calculated with kappa was 0.85. Fifteen studies were included. Treatment options included pelvic floor re-education (n=7), colonic irrigation (n=2) and sacral nerve stimulation (SNS) (n=6). Nine studies reported reduced incontinence scores and a decreased number of incontinent episodes. In 10 studies an improvement in resting and squeeze pressure was observed after treatment with pelvic floor re-education or SNS. Three studies reported improved quality of life after pelvic floor re-education. Significant improvement of the Fecal Incontinence Quality of Life Scale was found in three studies after SNS. Conclusion Conservative therapies such as pelvic floor re-education and colonic irrigation can improve anorectal function. SNS might be an effective solution in selected patients. However, methodologically qualitative studies are limited and randomized controlled trials are needed to draw evidence-based conclusions. © 2012 The Authors.

Abstract Background An anterior cruciate ligament injury may lead to deteriorations in postural stability. The goal of this study was to evaluate postural stability during the transition from double-leg stance to single-leg stance of both legs in anterior cruciate ligament injured subjects and non-injured control subjects with a standardized methodology. Methods Fifteen control subjects and 15 anterior cruciate ligament injured subjects (time after injury: mean (SD) = 1.4 (0.7) months) participated in the study. Both groups were similar for age, gender, height, weight and body mass index. Spatiotemporal center of pressure outcomes of both legs of each subject were measured during the transition from double-leg stance to single-leg stance in eyes open and eyes closed conditions. Movement speed was standardized. Findings The center of pressure displacement after a new stability point was reached during the single-leg stance phase was significantly increased in the anterior cruciate ligament injured group compared to the control group in the eyes closed condition (P <.001). No significant different postural stability outcomes were found between both legs within both groups (P >.05). No significant differences were found during the transition itself (P >.05). Interpretation The anterior cruciate ligament injured group showed postural stability deficits during the single-leg stance phase compared to the non-injured control group in the eyes closed condition. Using the non-injured leg as a normal reference when evaluating postural stability of the injured leg may lead to misinterpretations, as no significant differences were found between the injured and non-injured leg of the anterior cruciate ligament injured group. © 2015 Elsevier Ltd.

Objective: To investigate the reliability and validity of the measurement of lateral trunk motion (LTM) in two-dimensional (2D) video analysis of unipodal functional screening tests. Design: Observational study. Setting: Research laboratory. Participants: Forty-three injury-free female athletes. Main outcome measures: Knee valgus (KV) and lateral trunk motion (LTM) angles were measured with a standard digital camera during the single leg squat and the single leg drop vertical jump (SLDVJ). Three-dimensional motion analysis was used during the SLDVJ to measure peak external knee abduction moment (pKAM). Intraclass correlation coefficients were calculated to assess the intra- and intertester reliability of the LTM angle. Correlations between 2D angles and pKAM were calculated for the SLDVJ. Results: Excellent intraclass correlation coefficients for the LTM angle were found within (0.99-1.00) and between testers (0.98-0.99). The sum of KV and LTM was significantly correlated with the pKAM during the SLDVJ for the dominant ( r=-0.36; p=0.017) and non-dominant leg ( r=-0.32; p=0.034), while either angle alone was not. Conclusions: LTM can be measured with excellent intra- and intertester reliability. The combination of KV and LTM was moderately associated with pKAM and thus including LTM may aid assessment of movement quality and injury risk. © 2013 Elsevier Ltd.

Background: To compare the knee joint kinematics, kinetics and EMG activity patterns during a stepping-down task in patients with knee osteoarthritis (OA) with control subjects. Methods: 33 women with knee OA (early OA, n = 14; established OA n = 19) and 14 female control subjects performed a stepping-down task from a 20. cm step. Knee joint kinematics, kinetics and EMG activity were recorded on the stepping-down leg during the loading phase. Results: During the stepping-down task patients with established knee OA showed greater normalized medial hamstrings activity (p = 0.034) and greater vastus lateralis-medial hamstrings co-contraction (p = 0.012) than controls. Greater vastus medialis-medial hamstrings co-contraction was found in patients with established OA compared to control subjects (p = 0.040) and to patients with early OA (p = 0.023). Self-reported knee instability was reported in 7% and 32% of the patients with early and established OA, respectively. Conclusions: The greater EMG co-activity found in established OA might suggest a less efficient use of knee muscles or an attempt to compensate for greater knee laxity usually present in patients with established OA. In the early stage of the disease, the biomechanical and neuromuscular control of stepping-down is not altered compared to healthy controls. © 2016 Elsevier B.V.

The non-invasive nature of pedobarographic measurements is particularly attractive to researchers for analyzing and characterizing the impact of specific pathological foot conditions. However, adequate clinical use of pedobarographic technology requires a profound technical and methodological knowledge. Several papers summarized the technical capacities of pedobarographic technology. Moreover, methodological expertise has grown considerably during the last two decades. Therefore, two crucial decisions have to be made before pathomechanical modelling or functional interpretation of foot and lower limb disorders can be pursued. The first is the selection of the specific method to analyse the dynamic plantar footprint, and the second is the choice of parameters to quantify the results. In the first part of this paper, we review the different methods used to analyse the dynamic plantar footprint and discuss their conceptual backgrounds. We also aim to illustrate the clinical relevance of each method and elaborate on the future perspectives. In the second part, we review quantification methods of pedobarographic measurements. The latter is of primary relevance to clinicians and investigators with a special interest in foot and lower limb biomechanics.
