Performance of the 2017 EULAR/ACR Classification Criteria for adult and juvenile idiopathic inflammatory myopathies and their major subgroups: a scoping review.

The 2017 EULAR/ACR classification criteria for adult/juvenile idiopathic inflammatory myopathies (IIM) were established using a data-driven approach by an international group of myositis experts to allow classification of IIM and its major subtypes. Since their publication, the performance of the criteria has been tested in multiple cohorts worldwide and significant limitations have been identified. Moreover, the understanding and classification of IIM have evolved since 2017. This scoping review was undertaken as part of a large international project to revise the EULAR/ACR criteria and aims to i) summarise the evidence from the current literature on the performance characteristics of the 2017 EULAR/ACR classification criteria in various cohorts and IIM subtypes, and ii) delineate the factors that need to be considered in the revision of the classification criteria. A systematic search of Medline (via PubMed), Cumulative Index to Nursing and Allied Health Literature, and conference abstract archives was conducted independently by three investigators for studies on the EULAR/ACR criteria published between October 2017 and January 2023. This scoping review of 19 articles and 13 abstracts revealed overall good performance characteristics of the EULAR/ACR criteria for IIM, yet deficiencies in lack of inclusion of certain IIM subtypes, such as immune mediated necrotising myopathy, amyopathic dermatomyositis, antisynthetase syndrome and overlap myositis. Published modifications that may improve the performance characteristics of the criteria for classification of IIM subtypes were also summarised. The results of this review suggest that a revision of the EULAR/ACR criteria is warranted.

Three-Dimensional Instrumented Gait Analysis for Children With Cerebral Palsy: An Evidence-Based Clinical Practice Guideline.

BACKGROUND: Children with cerebral palsy (CP) who walk have complex gait patterns and deviations often requiring physical therapy (PT)/medical/surgical interventions. Walking in children with CP can be assessed with 3-dimensional instrumented gait analysis (3D-IGA) providing kinematics (joint angles), kinetics (joint moments/powers), and muscle activity. PURPOSE: This clinical practice guideline provides PTs, physicians, and associated clinicians involved in the care of children with CP, with 7 action statements on when and how 3D-IGA can inform clinical assessments and potential interventions. It links the action statement grades with specific levels of evidence based on a critical appraisal of the literature. CONCLUSIONS: This clinical practice guideline addresses 3D-IGA's utility to inform surgical and non-surgical interventions, to identify gait deviations among segments/joints and planes and to evaluate the effectiveness of interventions. Best practice statements provide guidance for clinicians about the preferred characteristics of 3D-IGA laboratories including instrumentation, staffing, and reporting practices.Video Abstract: Supplemental digital content available at http://links.lww.com/PPT/A524.

Comparison of gait between walking up and down an incline with a walking device in older adults.

To identify the gait differences between cane and rolling walker (RW) use on incline and how these walking devices were received and used, 26 qualified older adults walked randomly on downward and upward with a cane and a RW respectively. With the RW use, downward walking show a faster velocity, higher cadence, less stance time, bigger steps and strides than upward walking (p≤.05); but no differences were seen with cane use. When comparing walking between a RW and a cane, those using a cane had faster velocity, larger step and stride lengths (P≤.01) but only during the upward condition. Incline surface plays a critical role in gait differences when walking with walking device. Geriatric professionals need to know the changes in gait that result from the type of device being used and need to incorporate this knowledge in the education provided to older adults for proper use of a walking device.

Instrumented Gait Analysis (IGA) for Management of Children With Cerebral Palsy: A Needs Assessment Survey.

PURPOSE: This needs assessment survey identifies the priorities of the clinical and research communities involved with the use of instrumented gait analysis (IGA) for a clinical practice guideline on IGA use with children with cerebral palsy (CP). METHODS: Thirteen Likert scale questions asked about the importance of topics related to IGA. Other questions addressed respondents' demographics, experience with IGA, patient populations, and gait laboratory characteristics. Several open-ended questions were included and analyzed. RESULTS: The survey was completed by 43 physical therapists and 53 non-physical therapists involved with IGA. More than 90% rated the following as critically or highly important: reliability and validity of IGA to identify gait pathology (94%); ability to longitudinally track gait pathology (93%); use in planning interventions (93%); use in evaluating outcomes (93%); and definition of IGA (90%). CONCLUSIONS AND RECOMMENDATIONS FOR CLINICAL PRACTICE: This needs assessment survey identified the topic priorities of clinicians and practitioners who use IGA for the management of children with CP. These results will guide the development of a clinical practice guideline on the use of IGA for the management of CP.

Postural effect on gait characteristics by using rolling walkers.

This study was to examine the effect of leaning-forward posture (LFP) on gait parameters while using a rolling walker (RW). A cross-sectional study was conducted in which 23 older female adults were asked to walk with a RW on the GaitRite walkway in two posture situations: upright posture, and LFP caused by pushing the RW forward and then following the RW. The temporal and spatial gait parameters were obtained for data analysis. Results showed that compared with the upright posture, participants with LFP demonstrated significantly increased cadence, decreased velocity and gait cycle time (both swing and stance time decreased). Of spatial parameters, both step and stride length significantly decreased, but the base of support increased significantly. These indicate that LFP during ambulation with a RW could lead participants to a shuffling-like (many steps on short distance) gait pattern. They may help clinicians find proper rehabilitation interventions and appropriate patient education for this specific postural presentation.

Temperature- and Pressure-Regulating Insoles for Prevention of Diabetic Foot Ulcers.

Diabetic foot ulcers (DFUs) pose a major threat to the United States healthcare system as well as patients and their families. High ulcer recurrence rates indicate that existing preventive measures are not effective. A new generation of multimodal preventive devices may reduce ulceration and amputation rates. Because previous research has revealed that tissue maintained at cooler temperatures is more resistant to breaking down, the evaluated technology may prevent foot ulceration. The purpose of this study was to test previously designed Temperature and Pressure Monitoring and Regulating Insoles (TAPMARI) in diabetic neuropathic and healthy subjects. A cooling unit, a mini-water pump, a battery pack, and a microcontroller (or simply thermostat) were placed inside a box attached to the subjects' calf, which provided cooling inside the shoe. The microcontroller was set at 28°C. Eight subjects provided informed consent, 3 of whom had diabetic neuropathy. Subjects used the instrumented shoe on the right foot and the matching control shoe on the left and walked on a treadmill for 5 minutes at self-selected speeds. Baseline and postwalking thermographs were obtained with a thermal camera. At the 2-hour midpoint, subjects again walked on the treadmill for 5 minutes at self-selected speeds. Second baseline and postwalking thermographs were captured. Plantar pressure distributions were also quantified. The TAPMARI successfully regulated foot temperatures at or below the target temperature. The mean baseline temperature of the right (regulated) and left (control) feet were 28.1 ± 1.9°C (mean ± standard deviation) for all subjects. The mean temperatures at the end of the study were 25.9 ± 2.5°C (right) and 31.7 ± 1.6°C (left) in all subjects. In the diabetic neuropathy group, the final mean temperatures were 27.5 ± 2.4°C (right) and 31.6 ± 0.8°C (left), which indicated that the temperature goal was met inside the instrumented shoe. By regulating temperatures, TAPMARI may reduce the metabolic demands in the foot and prevent cell autolysis by eliminating the imbalance between oxygen demand and supply. This study warrants further development and testing of TAPMARI as well as investigating the clinical effectiveness in preventing DFUs.

Deep Diaphragmatic Breathing-Anatomical and Biomechanical Consideration.

Background: Deep diaphragmatic breathing (DDB) involves slow and fully contraction of the diaphragm with expansion of the belly during inhalation, and slow and fully contraction of the abdominal muscles with reduction of the belly during exhalation. It is the key component of the holistic mind-body exercises commonly used for patients with multimorbidity. Purpose: The purpose of this study was to re-visit and address the fundamental anatomical and biomechanical consideration of the DDB with the relevant literature. Method: Peer-reviewed publications from last the 15 years were retrieved, reviewed, and analyzed. Findings: In this article, we described the updated morphological and anatomical characteristics of the diaphragm. Then, we elucidated in a biomechanical approach how and why the DDB can work on the gastrointestinal, cardiopulmonary, and nervous systems as well as on regulating the intra-abdominopelvic pressure and mind-body interaction to coordinate the diaphragm-pelvic floor-abdominal complex for a variety of physical and physiological activities. Conclusion: Understanding of this updated DDB knowledge may help holistic healthcare professionals including holistic nurses provide better patient education and care management during the DDB or DDB-based mind-body intervention time.

Estimation of B-inhibin and anti mullerian hormone in functional azoospermia and their correlations with surgical sperm retrieval: A prospective case-control study.

OBJECTIVES: The current study estimated the levels of anti mullerian hormone (AMH) and inhibin-B and reproductive hormones in non obstructive azoospermic (NOA) cases and obstructive azoospermic (OA) cases as well as comparing between them as regards the sensitivity and specificity in determining the sperm retrieval hope in the NOA cases. Finally, we analyzed any potential correlation between all the hormones measured in the current study. METHODS: The current case control study was conducted at the andrology outpatient clinic from June (2021) to March (2022). The study recruited 135 participants divided equally into three groups NOA cases, OA cases and controls, respectively. RESULTS: The mean inhibin-B was significantly lower in the NOA cases compared to the OA cases and the controls. There was a positive moderate correlation between AMH and Inhibin-B. Also, there was a positive moderate correlation between inhibin-B and free testosterone (FT) and positive weak correlation between beta Inhibin and leutinizing hormone (LH). CONCLUSIONS: The current study asserts the observation that inhibin-B is also expressed by Leydig cells as it has demonstrated positive correlations with FT and LH.

Long-term group exercise for people with Parkinson's disease: a feasibility study.

BACKGROUND AND PURPOSE: Aerobic and strengthening exercises have been shown to benefit people with Parkinson's disease (PD) on the basis of highly structured, short-term, clinical protocols. This study extended previous research by investigating feasibility of an ongoing, community-based, group exercise program for people with PD on the basis of short-term (10 weeks) and long-term (14 months) data. METHODS: Twenty people with PD (Hoehn and Yahr stages I to III) participated in at least one of four 10-week sessions. Classes were held twice weekly for 1 hour and included strength, flexibility, and balance and walking exercises. Evaluations were done 1.5 hours after medication intake 1 week before and 1 week after each session. Gait speed, 6-Minute Walk test (6MWT), "Timed Up and Go" test, and grip strength were used to assess physical function. Analysis of short-term results were based on 18 participants (2 dropped out prior to posttest), and long-term results were based on 8 participants who started in the first session continued through the 14-month period. RESULTS: Attendance rates were moderate to high (73% overall). No injuries were reported. Wilcoxon signed ranks tests based on each participant's first 10-week session demonstrated significant improvements in 6MWT, and grip strength. Long-term participants showed significant improvements in grip strength, and a trend toward improved 6MWT. Gait speed and Timed Up and Go test did not change significantly in the short or long terms. DISCUSSION/CONCLUSIONS: Our community-based group exercise program was safe, feasible, and appears to be effective. While some measures showed no improvement, there was no evidence of decline. This is an important outcome for persons with progressive neurological disorders, and suggests community-based group exercise is a promising option for people with PD.

Outcome measures in neurological physical therapy practice: part I. Making sound decisions.

Standardized outcome measures (OMs) are a vital part of evidence-based practice. Despite the recognition of the importance of OMs, recent evidence suggests that the use of OMs in clinical practice is limited. Selecting the most appropriate OM enhances clinical practice by (1) identifying and quantifying body function and structure limitations; (2) formulating the evaluation, diagnosis, and prognosis; (3) informing the plan of care; and (4) helping to evaluate the success of physical therapy interventions. This article (Part I) is the first of a 2-part series on the process of selecting OMs in neurological clinical practice. We introduce a decision-making framework to guide the selection of OMs and discuss 6 main factors-what to measure, the purpose of the measure, the type of measure, patient and clinic factors, psychometric factors, and feasibility-that should be considered when selecting OMs for clinical use. The framework will then be applied to a patient case in Part II of the series (see the article "Outcome Measures in Neurological Physical Therapy Practice: Part II. A Patient-Centered Process" in this issue).

Comparing Validity and Diagnostic Accuracy of Clarke's Angle and Foot Posture Index-6 to Determine Flexible Flatfoot in Adolescents: A Cross-Sectional Investigation.

OBJECTIVE: Clinically, the foot posture index-6 (FPI-6) and Clarke's angle (CA) are widely utilized to assess static foot posture; however, due to scarcity of scientific evidence, clinicians continue to debate the validity and diagnostic accuracy of these measures in children and adolescents. This study aimed to evaluate and compare the validity and diagnostic accuracy of the FPI-6 and CA in determining adolescents' flexible flatfoot between ages of 12 and 18 years, considering radiographic investigation as a reference standard measure. DESIGN: Cross-sectional study. SETTING: Governmental hospitals. PARTICIPANTS AND METHODS: A sample of 460 people (920 feet) with flexible flatfoot between the ages of 12 and 18 (15.23 ± 0.84 years) was enrolled in the study. The findings of the investigated measures were compared to the reference standard radiographic measure and plotted on the receiver operating characteristic (ROC) curve. The area under the ROC curve (AUC) was determined as a measure of FPI-6 and CA diagnostic accuracy. Intra-rater reliability, sensitivity, specificity, predictive values, and likelihood ratios of FPI-6 and CA were calculated and compared. The post-test probability of flatfoot was determined using the Fagan nomogram. RESULTS: CA had a substantially higher intra-rater reliability (ICC=0.99) than the FPI-6 (ICC=0.96), with p-value of 0.001. CA has greater sensitivity (98%) than FPI-6, as well as a superior specificity (99%), positive predictive value (98%), negative predictive value (98.9%), positive likelihood ratio (97), and a lower negative likelihood ratio (0.02). CA had such an area under ROC curve of 0.98 with a 95% confidence interval of 0.95-1.00, while FPI-6 had an area under ROC curve of 0.80 with a 95% confidence interval of (0.77-0.85). CONCLUSION: FPI-6 and Clarke's angle are both valid and diagnostically accurate clinical tests for flatfoot detection, with Clarke's angle outperforming FPI-6 in adolescents aged 12 to 18 years with a normal BMI.

Treatment effect and mechanism of Fu's subcutaneous needling among patients with shoulder pain: A retrospective pilot study.

Fu's subcutaneous needling (FSN) is a new acupuncture therapy developed from acupuncture and Traditional Chinese Medicine models. The aim of this study was to investigate the effect of FSN on shoulder pain. In this retrospective comparative study, patient case files with shoulder pain (Group A) treated with FSN were analyzed and compared with the same number of patients with shoulder pain (Group B) treated with conventional acupuncture and physical therapy. Motion-related pain (MRP), pain under pressure (PUP), and Range of motion (ROM) were collected before and after intervention. In the 68 patients, there were 39 males and 29 females, aged 21-53 years old (mean ± SD = 36.4 ± 8.15) with onset time ranging from 1 day to 7 days (mean ± SD = 3.15 ± 1.73). MRP, PUP, and ROM scores were improved after FSN intervention (p < .05). There were significant differences between group A and group B in MRP, PUP, and ROM scores after FSN intervention and 1 week follow-up (p < .05). No adverse events, such as fainting and sharp pain, occurred during the treatment process. FSN can be an effective rehabilitation intervention for improving shoulder pain and shoulder range of motion.

Instrumented gait analysis for management of gait disorders in children with cerebral palsy: A scoping review.

BACKGROUND: The use of Instrumented Gait Analysis (IGA) for the clinical management of individuals with cerebral palsy (CP) has increased in recent years. Previous systematic reviews have been completed to evaluate and summarize the evidence related to the efficacy of IGA in general. However, a focused summary of research studies on IGA for children with CP related gait disorders is needed. RESEARCH QUESTION: The purpose of the current work was to perform a scoping review to describe and categorize the range of existing literature about IGA as applied to the clinical management of children with CP related gait disorders. METHOD: A health sciences librarian developed a search strategy to include four key inclusion criteria of original research study, population included children with CP, study employed IGA, available in English. The available literature was organized into six study categories: reliability and validity, documentation of subgroups or model development, IGA for clinical decision making, effectiveness of treatments that depend on IGA, cost effectiveness, IGA used to evaluate the outcome of surgical, medical or rehabilitation treatment. RESULTS: 909 studies met the inclusion criteria and were placed into the six study categories. 14 % of studies were in reliability and validity, 33 % in subgroups or modeling, 2% in IGA for clinical decision making, 2% in treatments that depend on IGA, 1% in cost effectiveness, and 49 % of studies had IGA used as an outcome measure for treatment. SIGNIFICANCE: This scoping review has documented the wide range, diversity and extent of original research studies investigating the use of IGA for the clinical management of children with CP related gait disorders. The large volume of studies provides a basis for future work to develop a CPG about the use of IGA for the clinical management of children with CP related gait disorders.

Aquatic therapy for a child with type III spinal muscular atrophy: a case report.

Spinal muscular atrophy (SMA) is a neuromuscular disorder characterized by degeneration of alpha motor neurons. This case report describes an aquatic therapy program and the outcomes for a 3-year-old girl with type III SMA. Motor skills were examined using the 88-item Gross Motor Function Measure (GMFM), the Peabody Developmental Motor Scales (PDMS-2), and the GAITRite system. The child received aquatic therapy twice per week for 45-min sessions, for 14 weeks. The intervention included aquatic activities designed to improve gross motor skills and age-appropriate functional mobility. The GMFM total score improved by 11% following the intervention. The Standing Dimension score improved by 28% and the Walking, Running, and Jumping Dimension score improved by 18%. The gross motor quotient for the PDMS-2 improved from 66 to 74. The child's gait showed improvement in walking velocity, stride length, and single-limb support time as a percentage of the gait cycle. The outcomes of this case report demonstrate the successful improvement of gross motor function and gait in a 3-year-old child with SMA. This study provides clinical information for therapists utilizing aquatic therapy as a modality for children with neuromuscular disorders.

Effects of prolonged standing on gait in children with spastic cerebral palsy.

The purpose of this study was to determine the effects of prolonged standing on gait characteristics in children with spastic cerebral palsy. Six children with spastic cerebral palsy participated in this study with an average age of 6.5 years (SD = 2.5, range = 4.0-9.8 years). A reverse baseline design (A-B-A) was used over a 9-week period. During phase A, the children received their usual physical therapy treatment. During phase B, children received the prolonged standing program three times per week, in addition to their usual physical therapy treatment. During phase A2, children received their usual physical therapy treatment. Gait analysis and clinical assessment of spasticity were performed before and after each phase. Analysis of variance (ANOVA) for repeated measurements was used to test for changes in gait measures across the four measurement sessions. Friedman's was used to test for changes in muscle tone (Modified Ashworth Scale) across the four measurement sessions. Stride length (p <.001), gait speed (p <.001), stride time (p <.001), stance phase time (p <.001), double support time (p <.003), muscle tone (p <.02), and peak dorsiflexion angle during midstance (p <.004) improved significantly following the intervention phase. The results of this study demonstrate that the gait pattern of children with cerebral palsy classified as level II or III on the Gross Motor Functional Classification System (GMFCS) improved by a prolonged standing program. However, these improvements were not maintained at 3 weeks. Further research is necessary with larger sample sizes to replicate these findings and determine specific "dosing" for standing programs to create long-lasting functional effects on gait.

Effect of lidocaine iontophoresis combined with exercise intervention on gait and spasticity in children with spastic hemiplegic cerebral palsy: A randomized controlled trial.

BACKGROUND: Gait deviations and spasticity are common impairments seen in children with cerebral palsy (CP) and may interfere with functional performance and effective walking pattern. Lidocaine iontophoresis is effective for reducing muscle spasticity in adults. PURPOSE: To investigate the effect of lidocaine epinephrine iontophoresis combined with exercises on gait and spasticity in children with spastic hemiplegic cerebral palsy (HCP). METHODS: Thirty children with spastic HCP aged 4-6 (5.20±0.32) years were randomly assigned to the experimental group (n = 15) and control group (n = 15). Children in both groups received one hour of exercises, three times a week for three months. Children in the experimental group received 2% lidocaine iontophoresis immediately before the exercises. The lidocaine iontophoresis was delivered for 20 minutes (1mA/min). Spatio-temporal gait parameters were assessed within one week before and after the intervention using 3D motion analysis. Surface electromyography was used to assess muscle tone using H/M ratio of the soleus muscle. ANOVA was used to investigate the differences between experimental and control groups. Statistical significance was set at P value less than 0.05. RESULTS: There was no difference between groups at baseline. Post-intervention, the experimental group showed significant improvements when compared to the control group for gait speed (p = 0.03), stride length (p = 0.04), cadence (p = 0.0001), cycle time (p = 0.0001), and H/M ratio (p = 0.02). CONCLUSION: Lidocaine iontophoresis combined with exercises was effective in improving gait spatiotemporal parameters and reducing spasticity in children with CP.

Validity and diagnostic accuracy of foot posture Index-6 using radiographic findings as the gold standard to determine paediatric flexible flatfoot between ages of 6-18 years: A cross-sectional study.

BACKGROUND: Diagnosis of flexible flatfoot is usually based upon radiographic or clinical measures. Radiographic measures pose a potential risk of radiation exposure especially in Paediatric population. Clinicians need a valid, accurate, easily used, noninvasive and cost effective measure to evaluate static foot posture clinically. Although, foot posture index-6 (FPI-6) are commonly used in clinical practice, its validity and diagnostic accuracy in evaluation of paediatric flexible flatfoot have not been fully proven yet. OBJECTIVES: To investigate validity and diagnostic accuracy of FPI-6 to determine Paediatric flexible flatfoot between ages of 6-18 years using radiographic findings as the gold standard measure. STUDY DESIGN: Cross-sectional study. METHODS: A cross-sectional study conducted on 612 participants (1224 feet) with flexible flatfoot aged 6-18 years (mean age ± standard deviation of 12.36 ± 3.39 years). The results of FPI-6 were compared to the gold standard radiographic measures and displayed on the receiver operating characteristic curve. Intra-rater reliability, sensitivity, specificity, predictive values and likelihood ratios were calculated. Posttest probability was calculated from Fagan nomogram. RESULTS: FPI-6 demonstrate high intra-rater reliability (ICC = 0.96) with p value < 0.001. FPI-6 showed a sensitivity of 83.7%, a specificity of 80.4, a positive predictive value of 64.7, a negative predictive value of 92, a positive likelihood ratio of 4.62 and a negative likelihood ratio of 0.20. FPI-6 shows moderate diagnostic accuracy [AUC = 0.82; 95%CI (0.78-0.85)]. CONCLUSION: FPI-6 is valid with moderate diagnostic accuracy to determine paediatric flexible flatfoot between ages of 6-18 years.

Overground gait training for individuals with chronic stroke: a Cochrane systematic review.

BACKGROUND AND PURPOSE: : Overground gait training-observation and cueing of patient's walking pattern along with related exercises-forms a major part of rehabilitation services for individuals with chronic stroke in almost every setting. This report of a Cochrane systematic review assessed the effects of overground gait training on walking ability for individuals with mobility deficits subsequent to chronic stroke. DATA SOURCES: : We searched the Cochrane Stroke Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, Science Citation Index Expanded, http://www.clinicaltrials.gov, among other databases through spring 2008. We also searched reference lists and contacted authors and trial investigators. REVIEW METHODS: : Only randomized controlled trials comparing overground physical therapy gait training with a placebo or no treatment condition were included. RESULTS: : Nine studies involving 499 participants were included. We found no evidence of a benefit on walking function, the primary variable, based on three studies (n = 269). Some performance variables did show significant effects. Walking speed increased by 0.07 m/sec [95% confidence interval (CI), 0.05-0.10] based on seven studies (n = 396), Timed Up and Go test improved by 1.81 seconds (95% CI, -2.29 to -1.33) based on three studies (n = 118), and six-minute walk test increased by 26.06 m (95% CI, 7.14-44.97) based on four studies (n = 181). CONCLUSIONS: : We found insufficient evidence to determine whether overground physical therapy gait training benefits walking function in individuals with chronic stroke, although limited evidence suggests potential benefits for some performance variables. High-quality randomized controlled trials are needed to replicate and extend these findings.

Overground physical therapy gait training for chronic stroke patients with mobility deficits.

BACKGROUND: Overground gait training forms a major part of physical therapy services for chronic stroke patients in almost every setting. Overground gait training refers to physical therapists' observation and cueing of the patient's walking pattern along with related exercises, but does not include high-technology aids such as functional electrical stimulation or body weight support. OBJECTIVES: To assess the effects of overground physical therapy gait training on walking ability for chronic stroke patients with mobility deficits. SEARCH STRATEGY: We searched the Cochrane Stroke Group Trials Register (last searched March 2008), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2008), MEDLINE (1966 to May 2008), EMBASE (1980 to May 2008), CINAHL (1982 to May 2008), AMED (1985 to March 2008), Science Citation Index Expanded (1981 to May 2008), ISI Proceedings (Web of Science, 1982 to May 2006), Physiotherapy Evidence Database (http://www.pedro.org.au/) (May 2008), REHABDATA (http://www.naric.com/research/rehab/) (1956 to May 2008), http://www.clinicaltrials.gov (May 2008), http://www.controlled-trials.com/ (May 2008), and http://www.strokecenter.org/ (May 2008). We also searched reference lists of relevant articles, and contacted authors and trial investigators. SELECTION CRITERIA: Randomised controlled trials comparing overground physical therapy gait training with a placebo intervention or no treatment for chronic stroke patients with mobility deficits. DATA COLLECTION AND ANALYSIS: Pairs of authors independently selected trials. Three authors independently extracted data and assessed quality. We contacted study authors for additional information. MAIN RESULTS: We included nine studies involving 499 participants. We found no evidence for a benefit on the primary variable, post-test gait function, based on three studies with 269 participants. Uni-dimensional performance variables did show significant effects post-test. Gait speed increased by 0.07 metres per second (95% confidence interval (CI) 0.05 to 0.10) based on seven studies with 396 participants, timed up-and-go (TUG) test improved by 1.81 seconds (95% CI -2.29 to -1.33), and six-minute-walk test (6MWT) increased by 26.06 metres (95% CI 7.14 to 44.97) based on four studies with 181 participants. We found no significant differences in deaths/disabilities or in adverse effects, based on published reports or personal communication from all of the included studies. AUTHORS' CONCLUSIONS: We found insufficient evidence to determine if overground physical therapy gait training benefits gait function in patients with chronic stroke, though limited evidence suggests small benefits for uni-dimensional variables such as gait speed or 6MWT. These findings must be replicated by large, high quality studies using varied outcome measures.

Effects of task-oriented training on mobility function in children with cerebral palsy.

BACKGROUND/PURPOSE: Improvement in mobility function has been the primary goal in the rehabilitation of children with cerebral palsy. Few studies have examined the effectiveness of task-oriented strength training for children with cerebral palsy. The purpose of this study was to examine the effects of task-oriented strength training on mobility function in children with cerebral palsy. STUDY DESIGN: A single-blind, randomized controlled trial with pre-training and post-training evaluations. MATERIALS AND METHODS: Ten children with cerebral palsy (GMFCS levels I-III) were randomly assigned to an experimental group (N = 5) or control group (N = 5). Mobility function was assessed using the Gross Motor Function Measure (GMFM) and the Timed "Up and Go" (TUG) test. Participants in the control group received conventional physical therapy focused on improving walking and balance through facilitation and normalization of movement patterns. Participants in the experiment group received task-oriented strength training focused on strengthening the lower extremities and practicing functional tasks similar to those the child performs during daily activities. RESULTS: After the 5-week training period there were significant improvements in the experimental group for dimension D (p = 0.009), and dimension E (p = 0.009) of the GMFM. The experimental group significantly reduced the time taken to complete the TUG (p = 0.017). CONCLUSION/SIGNIFICANCE: This study supports the efficacy of task-oriented strength training for improving mobility function in children with cerebral palsy. The findings demonstrate that the application of a task-oriented strength training program is linked to positive functional outcomes. The results suggest that children with cerebral palsy may benefit from a task-oriented strength training program. Further studies with a larger randomized sample and longer post-intervention follow-up are necessary to document the long-term effects of participation in task-oriented strength training programs in the cerebral palsy population.
