Pediatric Rehabilitation Therapy and Physiotherapy Education in China.

AIMS: To explore the pediatric rehabilitation curriculum, clinical placement, faculty characteristics, facilitators and barriers to curriculum implementation, and satisfaction of graduates of entry-level programs of rehabilitation therapy and physiotherapy in China. METHODS: Two online cross-sectional surveys were conducted. With stratified random sampling, faculty were contacted to provide information on pediatric rehabilitation education in Survey A. In Survey B, the satisfaction of 2019 graduates was collected. Fifty-three faculty members (response rate 96.4%) completed Survey A and 154 graduates (response rate 85.6%) completed Survey B. RESULTS: There were variations in pediatric rehabilitation curriculum setting, clinical placement, and faculty characteristics. The key facilitator to implementation was a stand-alone pediatric course. The insufficient number of teachers was identified as the major barrier. The median satisfaction level of all 2019 graduates for curricular setting, faculty and placement was 4 (satisfied). The satisfaction level of 2019 graduates of programs accredited by the World Physiotherapy was statistically higher than that of graduates of non-accredited programs in curricular setting and faculty. CONCLUSIONS: The results support the need for faculty development and guidelines on minimum standards for entry-level pediatric rehabilitation education in China.

Effects of Abdominal Binders on Postoperative Pain and Functional Recovery: A Systematic Review and Meta-Analysis.

OBJECTIVE: This study aimed to assess the effectiveness of abdominal binders (ABs) on postoperative pain and functional recovery in patients receiving abdominal surgery. METHODS: The Pubmed, Embase, Cochrane Library, and PEDro databases were searched for clinical trials published up to November 30, 2019. Randomized controlled trials that compared the effects of wearing an AB to not wearing an AB in participants after abdominal surgery were included. The primary outcomes were pain, pulmonary function, and physical function, as assessed by the visual analog scale score, a spirometry device, and the 6-minute walk test, respectively. The registration number of this review in PROSPERO is CRD42020165303. RESULTS: Fourteen trials involving 1,317 participants were included. Pooled estimates for the visual analog scale score and the 6-minute walk test showed significant differences between the AB group and the control group, especially on the fourth day following surgery (mean difference [MD] = -2.82, 95% confidence interval [CI] = -3.41 to -2.22; P < 0.00001; MD = 50.97 meters, 95% CI = 39.99-61.95 m; P < 0.00001). However, no significant differences were found in pulmonary function (forced vital capacity [FVC]: MD = 0.01, 95% CI = -0.29 to -0.32; P = 0.94; forced expiratory volume during the first second [FEV1]: MD = -0.05, 95% CI = -0.24 to 0.14; P = 0.63; FEV1/FVC: MD = 3.14, 95% CI = -2.78 to 9.06; P = 0.30). CONCLUSION: ABs probably improve postoperative pain and physical function, especially on the fourth day or more following abdominal surgery, but they have no effects on pulmonary function.

Effects of mirror therapy on walking ability, balance and lower limb motor recovery after stroke: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To investigate the effects of mirror therapy on walking ability, balance and lower limb motor recovery in patients with stroke. METHOD: MEDLINE, EMBASE, Web of Science, CENTRAL, PEDro Database, CNKI, VIP, Wan Fang, ClinicalTrials.gov, Current controlled trials and Open Grey were searched for randomized controlled trials that investigated the effects of mirror therapy on lower limb function through January 2018. The primary outcomes included were walking speed, mobility and balance function. Secondary outcomes included lower limb motor recovery, spasticity and range of motion. Quality assessments were performed with the PEDro scale. RESULTS: A total of 13 studies ( n = 572) met the inclusion criteria. A meta-analysis demonstrated a significant effect of mirror therapy on walking speed (mean difference (MD) 0.1 m/s, 95% confidence interval (CI): 0.08 to 0.12, P < 0.00001), balance function (standard mean difference (SMD) 0.66, 95% CI: 0.43 to 0.88, P < 0.00001), lower limb motor recovery (SMD 0.83, 95% CI: 0.62 to 1.05, P < 0.00001) and passive range of motion of ankle dorsiflexion (MD 2.07°, 95% CI: 082 to 3.32, P = 0.001), without improving mobility (SMD 0.43, 95% CI: -0.12 to 0.98, P = 0.12) or spasticity of ankle muscles (MD -0.14, 95% CI: -0.43 to 0.15, P = 0.35). CONCLUSION: The systematic review demonstrates that the use of mirror therapy in addition to some form of rehabilitation appears promising for some areas of lower limb function, but there is not enough evidence yet to suggest when and how to approach this therapy.

Effects of Tai Chi on balance and fall prevention in Parkinson's disease: a randomized controlled trial.

OBJECTIVES: To examine the effects of Tai Chi on balance and functional mobility in people with Parkinson's disease, and determine whether fall incidence could be reduced by the Tai Chi exercise. DESIGN: Single blinded randomized control trial with 6 months' follow-up. SETTING: A hospital and general community. PARTICIPANTS: Patients (n=76) diagnosed with idiopathic Parkinson's disease, over 40 years old, able to walk independently and fell at least one time during the past 12 months. INTERVENTIONS: The Tai Chi group (n=37) received 24-form Yang style Tai Chi exercise for 60 minutes each time, three times a week and lasted for 12 weeks. The control group (n=39) received no intervention. MAIN OUTCOME MEASURES: Berg Balance Scale (BBS), Unified Parkinson's Disease Rating Scale (UPDRS) III, Timed Up&Go (TUG) and occurrences of falls. RESULTS: The Tai Chi group improved more than the control group on the BBS (p<0.05), but there was no difference on UPDRS III scores and Timed Up&Go (p>0.05). During the 6-month follow-up, only 8 (21.6%) out of 37 patients in the Tai Chi group had experience of falls comparing to 19 (48.7%) out of 39 patients in the control group (p<0.05). The average times of falls were 0.30±0.62 in the Tai Chi group compared with 0.64±0.74 in the control group (p<0.05). CONCLUSIONS: Our findings suggested that Tai Chi exercise could improve the balance and decrease the fall risks in patients with Parkinson's disease.

Effectiveness of cerebellar vermis intermittent theta-burst stimulation in improving trunk control and balance function for patients with subacute stroke: a randomised controlled trial protocol.

INTRODUCTION: Balance impairments frequently occur after stroke. Achieving effective core trunk stability is the key to improving balance ability. However, there is still a lack of advanced well-defined rehabilitation protocols for balance improvement in patients with stroke. Intermittent theta-burst stimulation (iTBS) is a non-invasive brain activity modulation strategy that can produce long-term potentiation. The cerebellar vermis is a fundamental structure involved in balance and motor control. However, no study has demonstrated the therapeutic effect and potential mechanism of cerebellar vermis iTBS on balance after stroke. METHODS AND ANALYSIS: This study will be a prospective single-centre double-blind randomised controlled clinical trial with a 3-week intervention and 3-week follow-up. Eligible participants will be randomly allocated to the experimental group or the control group in a 1:1 ratio. After routine conventional physical therapy, patients in the experimental group will receive cerebellar vermis iTBS, whereas patients in the control group will receive sham stimulation. The overall intervention period will be 5 days a week for 3 consecutive weeks. The outcomes will be measured at baseline (T0), 3 weeks postintervention (T1) and at the 3-week follow-up (T2). The primary outcomes are Berg Balance Scale and Trunk Impairment Scale scores. The secondary outcomes are balance test scores via the Balance Master system, muscle activation of the trunk and lower limbs via the surface electromyography recordings, cerebral cortex oxygen concentrations measured via the resting-state functional near-infrared spectroscopy, Fugl-Meyer Assessment of Lower Extremity and Barthel index scores. ETHICS AND DISSEMINATION: This study was approved by the West China Hospital Clinical Trials and Biomedical Ethics Committee of Sichuan University. All participants will sign the informed consent form voluntarily. The results of this study will be published in peer-reviewed journals and disseminated at academic conferences. TRIAL REGISTRATION NUMBER: ChiCTR2200065369.

The Immediate Effects of Intermittent Theta Burst Stimulation of the Cerebellar Vermis on Cerebral Cortical Excitability During a Balance Task in Healthy Individuals: A Pilot Study.

Objective: This pilot study aimed to investigate the immediate effects of single-session intermittent theta-burst stimulation (iTBS) on the cerebellar vermis during a balance task, which could unveil the changes of cerebral cortical excitability in healthy individuals. Subjects: A total of seven right-handed healthy subjects (26.86 ± 5.30 years) were included in this study. Interventions: Each subject received single-session iTBS on cerebellar vermis in a sitting position. Main Measures: Before and after the intervention, all subjects were asked to repeat the balance task of standing on the left leg three times. Each task consisted of 15 s of standing and 20 s of resting. Real-time changes in cerebral cortex oxygen concentrations were monitored with functional near-infrared spectroscopy (fNIRS). During the task, changes in blood oxygen concentration were recorded and converted into the mean HbO2 for statistical analysis. Results: After stimulation, the mean HbO2 in the left SMA (P = 0.029) and right SMA (P = 0.043) significantly increased compared with baseline. However, no significant changes of mean HbO2 were found in the bilateral dorsolateral prefrontal lobe (P > 0.05). Conclusion: Single-session iTBS on the cerebellar vermis in healthy adults can increase the excitability of the cerebral cortex in the bilateral supplementary motor areas during balance tasks.

Cerebellar Intermittent Theta-Burst Stimulation Reduces Upper Limb Spasticity After Subacute Stroke: A Randomized Controlled Trial.

Objective: This study aims to explore the efficacy of cerebellar intermittent theta-burst stimulation (iTBS) on upper limb spasticity in subacute stroke patients. Methods: A total of 32 patients with upper limb spasticity were enrolled and randomly assigned to treatment with cerebellar iTBS or sham stimulation before conventional physical therapy daily for 2 weeks. The primary outcomes included the modified Ashworth scale (MAS), the modified Tardieu scale (MTS), and the shear wave velocity (SWV). The secondary outcomes were the H-maximum wave/M-maximum wave amplitude ratio (Hmax/Mmax ratio), motor-evoked potential (MEP) latency and amplitude, central motor conduction time (CMCT), and the Barthel Index (BI). All outcomes were evaluated at baseline and after 10 sessions of intervention. Results: After the intervention, both groups showed significant improvements in the MAS, MTS, SWV, and BI. In addition, patients treated with cerebellar iTBS had a significant increase in MEP amplitude, and patients treated with sham stimulation had a significant decrease in Hmax/Mmax ratio. Compared with the sham stimulation group, the MAS, MTS, and SWV decreased more in the cerebellar iTBS group. Conclusion: Cerebellar iTBS is a promising adjuvant tool to reinforce the therapeutic effect of conventional physical therapy in upper limb spasticity management after subacute stroke (Chinese Clinical Trial Registry: ChiCTR1900026516).

Low-Frequency Vibration Promotes Tumor Necrosis Factor-α Production to Increase Cartilage Degeneration in Knee Osteoarthritis.

OBJECTIVE: Low-frequency vibration accelerates cartilage degeneration in knee osteoarthritis (KOA) rat model. In this article, we investigated whether whole-body vibration (WBV) increases cartilage degeneration by regulating tumor necrosis factor-α (TNF-α) in KOA. DESIGN: Proteomics analysis was used to filter candidate protein from synovial fluid (SF) in KOA people after WBV. Enzyme-linked immunosorbent assay (ELISA) was used to estimate changes in TNF-α levels in SF. The C57 mice and TNF-α knock-out mice were sacrificed for the KOA model and WBV intervention. The cartilage was tested by ELISA, histology, terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL), immunohistochemistry, and reverse transcriptase polymerase chain reaction. Luciferase activity test in vitro study was conducted to confirm the relationship between TNF-α and the candidate protein. RESULTS: Differentially expressed proteins were enriched in the glycolytic process, glucose catabolic, and regulation of interleukin-8 (IL-8) secretion processes. Phosphoglycerate kinase, triosephosphate isomerase 1, T cell immunoglobulin- and mucin-domain-containing molecules 2, fumarylacetoacetate hydrolase (FAH), and TNF were the hub node. TNF-α expression increased in SF after WBV (P < 0.05). The cartilage was more degenerated in the TNF-α-/- mice group compared to controls. A significant change was observed in collagen II and FAH (P < 0.05). TNF-α expression improved in C57 mice (P < 0.05). Apoptosis of chondrocytes was inhibited in TNF-α-/- mice by the TUNEL test. Luciferase activity significantly increased in TNF-α + FAH-Luc cells (P < 0.05). CONCLUSION: A novel mechanism underlying WBV-triggered cartilage degeneration was found in KOA that demonstrated the critical regulatory function of TNF-α and FAH during WBV.

Cerebellar Theta Burst Stimulation on Walking Function in Stroke Patients: A Randomized Clinical Trial.

Objectives: The objective of this study was to explore the efficacy of cerebellar intermittent theta burst stimulation (iTBS) on the walking function of stroke patients. Methods: Stroke patients with walking dysfunction aged 25-80 years who had suffered their first unilateral stroke were included. A total of 36 patients [mean (SD) age, 53 (7.93) years; 10 women (28%)] were enrolled in the study. All participants received the same conventional physical therapy, including transfer, balance, and ambulation training, during admission for 50 min per day during 2 weeks (10 sessions). Every session was preceded by 3 min procedure of cerebellar iTBS applyed over the contralesional cerebellum in the intervention group or by a similar sham iTBS in control group. The groups were formed randomly and the baseline characteristics showed no significant difference. The primary outcome measure was Fugl-Meyer Assessment-Lower Extremity scores. Secondary outcomes included walking performance and corticospinal excitability. Measures were performed before the intervention beginning (T0), after the first (T1) and the second (T2) weeks. Results: The Fugl-Meyer Assessment for lower extremity scores slightly improved with time in both groups with no significant difference between the groups and over the time. The walking performance significantly improved with time and between group. Two-way mixed measures ANOVA showed that there was significant interaction between time and group in comfortable walking time (F 2,68 = 6.5242, P = 0.0080, η2 partial = 0.276, ε = 0.641), between-group comparisons revealed significant differences at T1 (P = 0.0072) and T2 (P = 0.0133). The statistical analysis of maximum walking time showed that there was significant interaction between time and groups (F 2,68 = 5.4354, P = 0.0115, η2 partial = 0.198, ε = 0.734). Compared with T0, the differences of maximum walking time between the two groups at T1 (P = 0.0227) and T2 (P = 0.0127) were statistically significant. However, both the Timed up and go test and functional ambulation category scale did not yield significant differences between groups (P > 0.05). Conclusion: Our results revealed that applying iTBS over the contralesional cerebellum paired with physical therapy could improve walking performance in patients after stroke, implying that cerebellar iTBS intervention may be a noninvasive strategy to promote walking function in these patients. This study was registered at ChiCTR, number ChiCTR1900026450.
