Satisfactory adherence to the Dutch physical therapy guideline for patients with a total knee arthroplasty. A survey study involving 103 specialised physical therapists.

OBJECTIVE: To explore and gain more insight into the usual preoperative and postoperative physical therapy (PT) treatment of patients with a total knee arthroplasty (TKA) among Dutch physical therapists experienced with TKA rehabilitation. Secondly, to evaluate physical therapists' adherence to guideline recommendations for postoperative rehabilitation. METHODS: In this cross-sectional study, physical therapists working in primary care within a designated Dutch hospital's catchment area were surveyed online. The survey queried PT treatment approaches before surgery, during hospitalisation, and after surgery. All data were analysed descriptively. When both education and all recommended exercise modalities were used postoperatively, therapists were considered fully adherent with the Dutch clinical practice guideline. RESULTS: One hundred and three therapists participated, representing a response rate of 58%. Postoperative PT treatment was applied by all therapists, of which 65 (63.1%) were fully adherent to the guideline. Partial adherence was mainly due to not using the aerobic exercise modality. Furthermore, beyond the modalities recommended in the guideline, a range of PT interventions were used. Preoperative treatment was applied by 73 therapists (70.9%). These 73 indicated that only a median of 20% (IQR 10%-40%) of their patients received preoperative PT. CONCLUSIONS: This study revealed satisfactory adherence to guideline recommendations on postoperative management of patients with a TKA among experienced physical therapists. Aerobic exercises were utilised less often or with inappropriate intensity. Correct adherence to guideline recommendations on aerobic exercise training can result in more physically active individuals and important general health benefits.

Exercise- and education-based prehabilitation before total knee arthroplasty: a pilot study.

OBJECTIVE: To determine the feasibility and estimates of effects of a supervised exercise- and education-based prehabilitation programme aiming to improve knee functioning compared with usual care in patients awaiting total knee arthroplasty. DESIGN: A randomized controlled pilot study. SUBJECTS: Patients receiving primary, unilateral total knee arthroplasty. METHODS: Patients randomized to the intervention group participated in a personalized 4-8-week prehabilitation programme before surgery. Feasibility of the intervention and self-reported knee functioning, pain, physical performance and hospital stay were assessed at baseline, immediately preoperatively, 6 and 12 weeks after surgery. RESULTS: Twenty patients (mean age 72.7±5.95 years) were enrolled in this study. The personalized prehabilitation programme was found to be feasible and safe, with an exercise adherence of 90%. Significant medium interaction effects between groups and over time favouring prehabilitation were reported for the sport subscale of the Knee Osteoarthritis Outcome Score (F(3/54) = 2.895, p = 0.043, η² = 0.139) and Tegner Activity Scale (F(2.2/39.1) = 3.20, p = 0.048, η² = 0.151). CONCLUSION: The absence of adverse events and high adherence to the programme, coupled with beneficial changes shown in the intervention group, support the conduct of a full-scale trial investigating the effectiveness of prehabilitation.

Dataset of 3D gait analysis in typically developing children walking at three different speeds on an instrumented treadmill in virtual reality.

In this article, gait data of typically developing (TD) children (24 boys/31 girls, mean (95% confidence interval) age 9.38 (8.51 - 10.25) years, body mass 35.67 (31.40 - 39.94) kg, leg length 0.73 (0.70 - 0.76) m, and height 1.41 (1.35 - 1.46) m) walking at different walking speeds is shared publicly. Raw and processed data is presented for each child separately and includes data of each single step of both legs. Beside, the subject demographics and the results from the physical examination are presented allowing to select TD children from the database to create a matched group, based on specific parameters (e.g. sex and body weight). For clinical application, gait data is also presented per age group, which provides quick insight into the normal gait pattern of TD children of varying age. Gait analysis was performed during treadmill walking in a virtual environment using the Computer Assisted Rehabilitation Environment (CAREN). The human body lower limb model with trunk markers (HBM2) was used as biomechanical model. Children walked at comfortable walking speed, 30% slower and 30% faster (random sequence) while wearing gymnastic shoes and a safety harness to prevent falling. For each speed condition, 250 steps were recorded. Data quality check, step detection and the calculation of gait parameters was done by custom made Matlab algorithms. Raw data files are provided per walking speed, for each child separately. The raw data is exported from the CAREN software (D-flow) and is provided in .mox and .txt files. It includes the output from the models such as subject data, marker and force data, kinematic data (joint angles), kinetic data (joint moments, GRFs, joint powers), as well as CoM data and EMG data (the last two are not described in this manuscript), for each speed condition and each child. Unfiltered and filtered data are included. C3D files with raw marker and GRF data were recorded in Nexus (Vicon software) and are available upon request. After analyzing the raw data into Matlab (R2016a, Mathworks) using custom made Matlab algorithms, processed data is obtained. The processed data is provided in .xls files and is also presented for each child separately. It contains spatiotemporal parameters, 3D joint angles, anterior-posterior and vertical ground reaction forces (GRF), 3D joint moments and sagittal joint power of each step of the left and right leg. In addition to each individual's data, overview files (.xls) are created per walking speed condition. These overviews present the averaged gait parameter (e.g. joint angle), calculated over all valid steps, of each child.

Prehabilitation Improves Knee Functioning Before and Within the First Year After Total Knee Arthroplasty: A Systematic Review With Meta-analysis.

OBJECTIVE: To assess whether prehabilitation influenced knee functioning before and within the first year after total knee arthroplasty (TKA) surgery. DESIGN: Intervention systematic review with meta-analysis. LITERATURE SEARCH: The authors searched the MEDLINE/PubMED, EMBASE, CINAHL, Cochrane Library, Physiotherapy Evidence Database, Web of Science, and Scopus databases from their inception until March 2022. STUDY SELECTION CITERIA: The authors included peer-reviewed articles comparing preoperative, short-, mid- or long-term effects of exercise-based physical therapy before primary unilateral TKA with TKA without prehabilitation. DATA SYNTHESIS: We assessed bias using the Cochrane Risk-of-Bias tool (ROB 2.0) and therapeutic validity using the i-CONTENT tool. Standardized mean differences (Hedges' g) and 95% confidence intervals (CIs) were calculated for knee functioning. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. RESULTS: Sixteen trials (968 participants) were included; 14 qualified for meta-analysis. Low to very low certainty of evidence favored prehabilitation over no intervention for improving knee functioning before (g = 1.23; 95% CI: 0.49, 1.97) and up to 3 months after TKA (short-term: 1 day to 1 month, g = 0.90; 95% CI: 0.18, 1.61; mid-term: 6 weeks to 3 months, g = 0.45; 95% CI: 0.06, 0.84). There were no significant between-group differences at long-term follow-up (6-12 months, g = 0.07; 95% CI: -0.17, 0.30). CONCLUSION: There was low to very low certainty of evidence that prehabilitation promotes superior knee functioning before and up to 3 months after TKA, compared to TKA alone. The long-term postoperative effects were inconclusive. J Orthop Sports Phys Ther 2022;52(11):709-725 Epub: 20 September 2022. doi:10.2519/jospt.2022.11160.

Comparison of sagittal plane gait characteristics between the overground and treadmill approach for gait analysis in typically developing children.

Background: Instrumented treadmills have become more mainstream in clinical assessment of gait disorders in children, and are increasingly being applied as an alternative to overground gait analysis. Both approaches differ in multiple elements of set-up (e.g., overground versus treadmill, Pug-in Gait versus Human Body Model-II), workflow (e.g., limited amount of steps versus many successive steps) and post-processing of data (e.g., different filter techniques). These individual elements have shown to affect gait. Since the approaches are used in parallel in clinical practice, insight into the compound effect of the multiple different elements on gait is essential. This study investigates whether the outcomes of two approaches for 3D gait analysis are interchangeable in typically developing children. Methods: Spatiotemporal parameters, sagittal joint angles and moments, and ground reaction forces were measured in typically developing children aged 3-17 years using the overground (overground walking, conventional lab environment, Plug-In Gait) and treadmill (treadmill walking in virtual environment, Human Body Model-II) approach. Spatiotemporal and coefficient of variation parameters, and peak values in kinematics and kinetics of both approaches were compared using repeated measures tests. Kinematic and kinetic waveforms from both approaches were compared using statistical parametric mapping (SPM). Differences were quantified by mean differences and root mean square differences. Results: Children walked slower, with lower stride and stance time and shorter and wider steps with the treadmill approach than with the overground approach. Mean differences ranged from 0.02 s for stride time to 3.3 cm for step width. The patterns of sagittal kinematic and kinetic waveforms were equivalent for both approaches, but significant differences were found in amplitude. Overall, the peak joint angles were larger during the treadmill approach, showing mean differences ranging from 0.84° (pelvic tilt) to 6.42° (peak knee flexion during swing). Mean difference in peak moments ranged from 0.02 Nm/kg (peak knee extension moment) to 0.32 Nm/kg (peak hip extension moment), showing overall decreased joint moments with the treadmill approach. Normalised ground reaction forces showed mean differences ranging from 0.001 to 0.024. Conclusion: The overground and treadmill approach to 3D gait analysis yield different sagittal gait characteristics. The systematic differences can be due to important changes in the neuromechanics of gait and to methodological choices used in both approaches, such as the biomechanical model or the walkway versus treadmill. The overview of small differences presented in this study is essential to correctly interpret the results and needs to be taken into account when data is interchanged between approaches. Together with the research/clinical question and the context of the child, the insight gained can be used to determine the best approach.

Evaluation of Allied Healthcare in Patients Recovering from Covid-19: Study Protocol and Baseline Data of s National Prospective Cohort Study.

OBJECTIVE: To report the study protocol and baseline characteristics of a prospective cohort study to evaluate longitudinal recovery trajectories of patients recovering from COVID-19 who have visited a primary care allied health professional. DESIGN: Report of the protocol and baseline characteristics for a prospective cohort study with a mixed-methods approach. PATIENTS: Patients recovering from COVID-19 treated by primary care dietitians, exercise therapists, occupational therapists, physical therapists and/or speech and language therapists in the Netherlands. METHODS: The prospective study will measure primary outcome domains: participation, health-related quality of life, fatigue, physical functioning, and costs, at baseline, 3, 6, 9 and 12 months. Interviews, on the patients' experiences with allied healthcare, will be held with a subsample of patients and allied health professionals. RESULTS: The cohort comprises 1,451 patients (57% female, mean age 49 (standard deviation 13) years). Preliminary results for the study cohort show that 974 (67%) of the participants reported mild/moderate severity symptoms during the infection period and patients reported severe restrictions in activities of daily living compared with previous research in other patient populations. Both quantitative and qualitative, will provide insight into the recovery of patients who are treated by allied health professionals. CONCLUSION: In conclusion, this will be the first comprehensive study to longitudinally evaluate the recovery trajectories and related costs of patients recovering from COVID-19 who are treated by allied health professionals in the Netherlands. This study will provide evidence for the optimal strategy to treat patients recovering from COVID-19 infection, including which patients benefit, and to what extent, from treatment, and which factors might impact their recovery course over time. The preliminary results of this study demonstrated the severity of restrictions and complaints at the start of therapy are substantial.

Physiotherapists' clinical use and acceptance of a telemonitoring platform during anterior cruciate ligament rehabilitation: a prospective clinical study.

PURPOSE: The aim of this study was to assess physiotherapists' clinical use and acceptance of a novel telemonitoring platform to facilitate the recording of measurements during rehabilitation of patients following anterior cruciate ligament reconstruction. Additionally, suggestions for platform improvement were explored. METHODS: Physiotherapists from seven Dutch private physiotherapy practices participated in the study. Data were collected through log files, a technology acceptance questionnaire and focus group meetings using the "buy a feature" method. Data regarding platform use and acceptance (7-point/11-point numeric rating scale) were descriptively analysed. Total scores were calculated for the features suggested to improve the platform, based on the priority rating (1 = nice to have, 2 = should have, 3 = must have). RESULTS: Participating physiotherapists (N= 15, mean [SD] age 33.1 [9.1] years) together treated 52 patients during the study period. Platform use by the therapists was generally limited, with the number of log-ins per patient varying from 3 to 73. Overall, therapists' acceptance of the platform was low to moderate, with average (SD) scores ranging from 2.5 (1.1) to 4.9 (1.5) on the 7-point Likert scale. The three most important suggestions for platform improvement were: (1) development of a native app, (2) system interoperability, and (3) flexibility regarding type and frequency of measurements. CONCLUSIONS: Even though health care professionals were involved in the design of the telemonitoring platform, use in routine care was limited. Physiotherapists recognized the relevance of using health technology, but there are still barriers to overcome in order to successfully implement eHealth in routine care.Implications for rehabilitationThe use and acceptance of the telemonitoring platform by physiotherapists for patients following anterior cruciate ligament reconstruction was limited.Suggestions made by therapists for platform improvement mainly related to user-friendliness and efficiency of workflow.Novel digital health technology needs to fit into daily routines, be easily accessible and easy to use for the end users.

Personalized teleprehabilitation in elective cardiac surgery: a study protocol of the Digital Cardiac Counselling randomized controlled trial.

Aims: Previous research has shown the possibility to use the pre-operative period to improve a patient's tolerance for surgery. However, there is limited experience with prehabilitation in cardiac surgery. The aim of this study is to evaluate the effect of a comprehensive personalized teleprehabilitation programme on major adverse cardiac events (MACE) in patients scheduled for elective cardiac surgery. Secondary outcomes are post-operative complications, cardiovascular risk factors, quality of life, and cost-effectiveness. Methods and results: In this single-centre randomized controlled trial, patients are eligible for inclusion when they are ≥18 years of age and cardiac surgery is scheduled at least 8 weeks from informed consent. Participants will be randomized to the teleprehabilitation group or the control group. After a digital baseline screening for perioperative risk factors, patients in the intervention arm can pre-operatively be referred to one or more of the prehabilitation modules (functional exercise training, inspiratory muscle training, psychological support, nutritional support, and/or smoking cessation). The programme is targeted at a duration of at least 6 weeks. It is executed by a multidisciplinary team using (video)calls and supported by a custom-made digital platform. During the pre-operative period, the platform is also used to inform patients about their upcoming surgery and for telemonitoring. Conclusion: Reducing perioperative risk factors might result in a reduction of MACE, post-operative complications, length of stay, and cardiovascular risk factors, as well as improved quality of life. Cost-effectiveness will be evaluated.

Range of motion of body segments is larger during the maximal instep kick than during the submaximal kick in experienced football players.

BACKGROUND: Football players with groin injury refrain from maximal kicking. Previous groin injury is related to decreased hip range of motion (ROM). Information on ROM differences between maximal and submaximal kicking within players is lacking. The first aim of this study is to quantify ROM of body segments during the maximal (MaxK) and submaximal (SubK) instep kick at four key points. The second aim is to study ROM differences of tension arc and movement trajectories between MaxK and SubK. METHODS: Maximal (100% ball speed) and submaximal (70% ball speed) instep kicks from 15 experienced football players were registered with motion capture. ROM of hip, spine, pelvis and knee segments were determined at four key points. Differences in segmental ROM for the tension arc and movement trajectories between MaxK and SubK were studied. Effect sizes (ES) were calculated. RESULTS: Ball speed was 98.8±9.0 km/h for MaxK and 69.5±7.1 km/h for SubK. Three key points timed similarly (P<0.05) for MaxK and SubK. MaxK shows increased ROM for all segments (P<0.05) but not for hip flexion. MaxK results in enlargement of tension arc and movement trajectories. Spine flexion (ES=3.2) and pelvis posterior tilt (ES=2.2) show the greatest relative increase. CONCLUSIONS: Maximal kicking shows larger segmental ROM than submaximal kicking. Enlargement of tension arc and movement trajectories relate to increased segmental velocity, according to biomechanical concepts. Central body actions play an important role in kicking. This information can be used to further identify kicking strategies in athletes with injury.

Timing characteristics of body segments during the maximal instep kick in experienced football players.

BACKGROUND: The first aim of this study was to describe duration and relative timing of the phases of the maximal instep kick. The second aim was to describe the concurrence of maximal range of motion, maximal angular acceleration, maximal angular deceleration and maximal angular velocity of body segments with four key points. METHODS: Twenty experienced football players performed three maximal instep kicks. The kicks were analysed using a full body, three-dimensional motion capture system. Camera recordings determined kicking leg events. The concurrence of peak kinematics of body segments with four key points was calculated. RESULTS: Duration and timing of five phases were identified. Key point maximal hip extension (51.4±5.0%) concurred significantly with maximal range of motion (ROM) of shoulder extension. Key point maximal knee flexion (63.6±5.2%) concurred significantly with maximal angular acceleration of spine flexion and pelvis posterior tilt. Key point knee flexion 90 degrees (69.3±4.9%) concurred significantly with maximal angular velocity of shoulder flexion and spine flexion, maximal angular deceleration of hip flexion and maximal angular acceleration of knee extension. Key point ball impact (75.2±5.2%) concurred significantly with maximal ROM of hip deflexion and pelvis anterior rotation and with maximal angular deceleration of spine flexion and pelvis anterior rotation. CONCLUSIONS: This study demonstrated that eleven peak kinematics of upper body and kicking leg segments, significantly concurred with four kicking leg positions. These results provide Key points for kicking coordination and stress the importance of dynamical coupling as a kicking mechanism.

Effectiveness of prolonged use of continuous passive motion (CPM), as an adjunct to physiotherapy, after total knee arthroplasty.

BACKGROUND: Adequate and intensive rehabilitation is an important requirement for successful total knee arthroplasty. Although research suggests that Continuous Passive Motion (CPM) should be implemented in the first rehabilitation phase after surgery, there is substantial debate about the duration of each session and the total period of CPM application. A Cochrane review on this topic concluded that short-term use of CPM leads to greater short-term range of motion. It also suggested, however, that future research should concentrate on the treatment period during which CPM should be administered. METHODS: In a randomised controlled trial we investigated the effectiveness of prolonged CPM use in the home situation as an adjunct to standardised PT. Efficacy was assessed in terms of faster improvements in range of motion (RoM) and functional recovery, measured at the end of the active treatment period, 17 days after surgery. Sixty patients with knee osteoarthritis undergoing TKA and experiencing early postoperative flexion impairment were randomised over two treatment groups. The experimental group received CPM + PT for 17 consecutive days after surgery, whereas the usual care group received the same treatment during the in-hospital phase (i.e. about four days), followed by PT alone (usual care) in the first two weeks after hospital discharge. From 18 days to three months after surgery, both groups received standardised PT. The primary focus of rehabilitation was functional recovery (e.g. ambulation) and regaining RoM in the knee. RESULTS: Prolonged use of CPM slightly improved short-term RoM in patients with limited RoM at the time of discharge after total knee arthroplasty when added to a semi-standard PT programme. Assessment at 6 weeks and three months after surgery found no long-term effects of this intervention Neither did we detect functional benefits of the improved RoM at any of the outcome assessments. CONCLUSION: Although results indicate that prolonged CPM use might have a small short-term effect on RoM, routine use of prolonged CPM in patients with limited RoM at hospital discharge should be reconsidered, since neither long-term effects nor transfer to better functional performance was detected.

Effectiveness of exercise therapy: a best-evidence summary of systematic reviews.

The purpose of this project was to summarise the available evidence on the effectiveness of exercise therapy for patients with disorders of the musculoskeletal, nervous, respiratory, and cardiovascular systems. Systematic reviews were identified by means of a comprehensive search strategy in 11 bibliographic databases (08/2002), in combination with reference tracking. Reviews that included (i) at least one randomised controlled trial investigating the effectiveness of exercise therapy, (ii) clinically relevant outcome measures, and (iii) full text written in English, German or Dutch, were selected by two reviewers. Thirteen independent and blinded reviewers participated in the selection, quality assessment and data-extraction of the systematic reviews. Conclusions about the effectiveness of exercise therapy were based on the results presented in reasonable or good quality systematic reviews (quality score > or = 60 out of 100 points). A total of 104 systematic reviews were selected, 45 of which were of reasonable or good quality. Exercise therapy is effective for patients with knee osteoarthritis, sub-acute (6 to 12 weeks) and chronic (> or = 12 weeks) low back pain, cystic fibrosis, chronic obstructive pulmonary disease, and intermittent claudication. Furthermore, there are indications that exercise therapy is effective for patients with ankylosing spondylitis, hip osteoarthritis, Parkinson's disease, and for patients who have suffered a stroke. There is insufficient evidence to support or refute the effectiveness of exercise therapy for patients with neck pain, shoulder pain, repetitive strain injury, rheumatoid arthritis, asthma, and bronchiectasis. Exercise therapy is not effective for patients with acute low back pain. It is concluded that exercise therapy is effective for a wide range of chronic disorders.
