Background Evidence about the role of physical therapy in perioperative care pathways to improve postoperative outcomes is growing. However, it is unclear whether research findings have been translated into daily practice. Objective The objectives of this study were to describe the current content and between-hospital variability of perioperative physical therapist management for patients undergoing colorectal, hepatic, or pancreatic resection in the Netherlands and to compare currently recommended state-of-the-art physical therapy with self-reported daily clinical physical therapist management. Design This was a cross-sectional survey study. Methods Hospital physical therapists were asked to complete an online survey about pre- and postoperative physical therapy at their hospital. To explore the variability of perioperative physical therapist management between hospitals, frequency variables were clustered to determine the level of uniformity. Latent class analysis was performed to identify clusters of hospitals with certain homogeneous characteristics on a 19-item dichotomous scale. Results Of 82 eligible Dutch hospitals, 65 filled out the survey (79.3%). Preoperative physical therapy was performed in 34 hospitals (54.0%; 2/65 responding hospitals were excluded from the data analysis). Postoperative physical therapy was performed in all responding hospitals, focusing mainly on regaining independent physical functioning. Latent class analysis identified a 3-class model. Hospitals in classes I and II were more likely to provide preoperative physical therapist interventions than hospitals in class III. Limitations The use of self-reported answers can lead to bias. Conclusions There was a wide degree of variability between hospitals regarding pre- and postoperative clinical physical therapist practice for patients opting for major abdominal surgery. Three different classes of daily practice were identified. Further translation of key research findings into clinical physical therapist practice is advised, especially for hospitals in which the physical therapist is not involved preoperatively. Moreover, improving uniformity by developing up-to-date clinical guidelines is recommended.

Background Recent research has shown that the Fitkids Treadmill Test (FTT) is a valid and reproducible exercise test for the assessment of aerobic exercise capacity in children and adolescents who are healthy. Objective The study objective was to provide sex- and age-related normative values for FTT performance in children and adolescents who were healthy, developing typically, and 6 to 18 years of age. Design This was a cross-sectional, observational study. Methods Three hundred fifty-six children and adolescents who were healthy (174 boys and 182 girls; mean age=12.9 years, SD=3.7) performed the FTT to their maximal effort to assess time to exhaustion (TTE). The least-mean-square method was used to generate sex- and age-related centile charts (P3, P10, P25, P50, P75, P90, and P97) for TTE on the FTT. Results In boys, the reference curve (P50) showed an almost linear increase in TTE with age, from 8.8 minutes at 6 years of age to 16.1 minutes at 18 years of age. In girls, the P50 values for TTE increased from 8.8 minutes at 6 years of age to 12.5 minutes at 18 years of age, with a plateau in TTE starting at approximately 10 years of age. Limitations Youth who were not white were underrepresented in this study. Conclusions This study describes sex- and age-related normative values for FTT performance in children and adolescents who were healthy, developing typically, and 6 to 18 years of age. These age- and sex-related normative values will increase the usefulness of the FTT in clinical practice.

Background Physical fitness levels in youth with osteogenesis imperfecta (OI) who use wheelchairs are unknown. The 10-m Shuttle Ride Test (SRiT) has recently been introduced as a field test to determine cardiorespiratory fitness in children with cerebral palsy who self-propel a wheelchair. Objective The purpose of this study was to investigate the feasibility and reproducibility of the SRiT, as well as the physiological responses to the SRiT, in youth with moderate-to-severe OI between 8 and 25 years of age who self-propel a wheelchair at least for long distances. Design A test-retest design was used. Methods Thirteen patients with OI (8 boys, 5 girls; mean±SD values for age=15.5±6.4 years) using a manual wheelchair performed 2 SRiTs within 2 weeks. Adverse events, reached stage, peak heart rate (HRpeak), peak respiratory exchange ratio (RERpeak), peak oxygen uptake (V̇o2peak), and peak minute ventilation (V̇epeak) were the main outcome parameters. Results and Discussion All participants performed a maximal effort at both SRiTs (mean±SD values for HRpeak of 195±9 beats per minute [bpm], RERpeak of 1.32±0.16, V̇o2peak of 25.4±5.6 mL·kg−1·min−1, and V̇epeak of 47.9±18.6 L·min−1), without adverse events. The intraclass correlation coefficient of the reached stage showed excellent reliability (.95). Limits of agreement (LoA) analysis revealed acceptable LoA for reached stage (mean bias=−0.58, range=−2.50 to +1.35). There was a low correlation between reached stage and V̇o2peak (r=.61 and r=.45 for the first and second SRiTs, respectively). Limitations The influence of wheelchair properties and individually adjusted wheelchair designs was not examined. Conclusions The SRiT appears to be a feasible, safe, and reproducible maximal field test in youth with OI using wheelchairs at least for long distances. This field test might be useful to provide an indication of physical fitness and to assess the efficacy of interventions on physical fitness in these patients.

Background The Steep Ramp Test (SRT), a feasible, reliable, and valid exercise test on a cycle ergometer, may be more appealing for use in children in daily clinical practice than the traditional cardiopulmonary exercise test because of its short duration, its resemblance to children's daily activity patterns, and the fact that it does not require respiratory gas analysis. Objective The aim of the present study was to provide sex- and age-related normative values for SRT performance in Dutch white children and adolescents who were healthy and 8 to 19 years old. Design This was a cross-sectional, observational study. Methods A total of 252 Dutch white children and adolescents, 118 boys (mean age=13.4 years, SD=3.0) and 134 girls (mean age=13.4 years, SD=2.9), performed the SRT (work rate increment of 10, 15, or 20 W·10 s−1, depending on body height) to voluntary exhaustion to assess peak work rate (WRpeak). Normative values are presented as reference centiles developed by use of generalized additive models for location, scale, and shape. Results Peak work rate correlated highly with age (r=.915 and r=.811), body mass (r=.870 and r=.850), body height (r=.922 and r=.896), body surface area (r=.906 and r=.885), and fat free mass (r=.930 and r=.902) in boys and girls, respectively. The reference curves demonstrated an almost linear increase in WRpeak with age in boys, even when WRpeak was normalized for body mass. In contrast, absolute WRpeak in girls increased constantly until the age of approximately 13 years, when it started to level off. Peak work rate normalized for body mass in girls showed only a slight increase with age until 14 years of age, when a slight decrease in relative WRpeak was observed. Limitations The sample may not have been entirely representative of the Dutch population. Conclusions The present study provides sex- and age-related normative values for SRT performance in terms of both absolute WRpeak and relative WRpeak, thereby facilitating the interpretation of SRT results by clinicians and researchers.
