Effect of postural balance training on gait parameters in children with cerebral palsy

Effects of proprioception and core stability training on gait parameters of deaf adolescents: a randomized controlled trial

The current study aimed to explore the effects of proprioception versus core stability training over 8 weeks on the gait parameters of deaf adolescents. A total of 20 deaf adolescents were randomized into two groups: one group receiving proprioception training (PT, n = 10), another group receiving core stability training (CST, n = 10), and eleven typically developing adolescents assigned into the control group (CON; n = 11). Gait was recorded by two digital cameras; then, using the Kinovea software, the parameters of gait included: gait velocity, cadence, stride length, stride time, stance time, and swing time were calculated in terms of percentages of the walking cycle. After 8 weeks of PT, no significant differences were observed for all gait parameters between PT and control groups (p > 0.05). Also, after 8 weeks of CST, no significant differences were observed in gait velocity and cadence between the CST and control groups (p > 0.05). However, after 8 weeks of CST, stride length (p = 0.02) was higher in the control group; Stride time (p = 0.03), stance time (p = 0.04) and swing time (p = 0.04) were higher in the CST group. Moreover, after 8 weeks of PT, values showed significant improvements in all gait parameters (p = 0.001). Also, after 8 weeks of CST, values showed significant improvements in gait velocity and cadence (p = 0.001), but no significant differences were observed in other gait parameters (p > 0.05). The findings of this study indicated that PT improved all gait parameters, whereas CST improved gait velocity and cadence. The results of the present study also demonstrated that PT had a greater effect on gait parameters of deaf adolescents compared with CST. It seems that PT induces more training effects than CTS for enhancing gait parameters of deaf adolescents.Trial registration: Clinical trial registry number: IRCT20170312033029N2.

The effects of balance board on the balance parameters in five children with spastic cerebral palsy

PURPOSE

This study evaluated the effects of an instrumented balance board on the balance parameters in children with spastic cerebral palsy by carrying out a pilot single-group pre-post clinical trial.

METHODS

Five children aged 5 to 15 years with spastic diplegia and a Gross Motor Function Classification System level of I or II were included. All participants attended 20 sessions with an instrumented balance board, 45 minutes per session, 3 times a week for 7 weeks. The main outcome measures included the center of pressure excursion, velocity, and overshoot during quiet standing with open and closed eyes. The assessments were performed in the mediolateral and anteroposterior directions at pre- and one week post-intervention.

RESULTS

Non-parametric tests showed that the excursion did not change significantly except in the mediolateral direction with eyes closed (p <  0.05). The velocity of the center of pressure improved in both directions and eye conditions (p <  0.05). Also, the maximum velocity decreased with eyes open (mediolateral, anteroposterior, and total) (p <  0.05), while the change was not significant with the eyes closed. The overshoot measurements did not change significantly.

CONCLUSION

It is recommended to consider balance board training for improving balance parameters in children with cerebral palsy.

Effect of upper extremity constraints on functional and dynamic postural control in children with hemiplegic cerebral palsy

PURPOSE

To compare the effects of upper extremity constraints on functional and dynamic postural control in children with hemiplegic cerebral palsy.

MATERIALS AND METHODS

Twelve children with hemiplegic cerebral palsy and 12 typically developing children ages 5 to 12 years (GMFCS I-II) were evaluated with the Timed Up and Go (TUG) and Biodex Balance System during three upper extremity (UE) conditions: 1) Free UEs (no constraints), 2) Simple UE constraint (unaffected/dominant UE constrained with a sling), and 3) Difficult UE constraint (Simple constraint plus the other UE holding cup of water).

RESULTS

The UE condition had significant effects on Overall Stability Index (OSI) (F_(2,44) = 24.899, p < .001), Medial-Lateral Stability Index (MLSI) (F_(2,44) = 4.380, p = .018), Anterior-Posterior Stability Index (F_(2,44) = 6.187, p = .004), and TUG scores (F_(2,44) = 113.372, p < .001). Group was significant for OSI (F_(1,22) = 7.906, p = .010), MLSI (F_(1,22) = 13.113, p = .002), and TUG (F_(1,22) = 36.282, p < .001).

CONCLUSIONS

The upper extremity appears to have a role in maintaining functional balance and postural stability in children with hemiplegic cerebral palsy and should be considered during intervention programs.

Reliability, minimum detectable change, and minimum clinically important difference of the balance subtest of the Bruininks-Oseretsky test of motor proficiency-second edition in children with cerebral palsy

PURPOSE

This study aimed to investigate the internal consistency, inter-rater, and test-retest reliability of the balance subtest of the Bruininks-Oseretsky test of motor proficiency-second edition (BOT-2) and to estimate the minimum detectable change (MDC) and minimum clinically important difference (MCID) of the balance subtest of the BOT-2 in children with cerebral palsy (CP).

METHODS

In total, 20 children with CP participated in the present study. Internal consistency, test-retest, and inter-rater reliability were computed to establish reliability of the balance subtest of the BOT-2. The MDC95 was estimated from the standard error of measurement (SEM) to determine a real change for an individual child with CP. The anchor- and distribution-based MCID were calculated to determine the smallest change that might be important to clinicians. For concurrent validity, the correlation between the balance subtest of the BOT-2 and the pediatric balance scale (PBS) were calculated using Spearman's correlation.

RESULTS

Internal consistency was good (Cronbach's alpha coefficient = 0.89). The BOT-2 had excellent test-retest (ICC = 0.99, p < 0.001) and inter-rater reliability (ICC = 0.99, p < 0.001). The balance subtest of the BOT-2 had an SEM of 0.70, MDC95 of 9.61, and MCIDs of 2.54 (anchor-based) and 1.38 (distribution-based). Additionally, there was a moderate positive correlation between the balance subtest of the BOT-2 and the PBS (Spearman's rho = 0.629, p = 0.003).

CONCLUSIONS

Our experimental results indicate that the balance subtest of the BOT-2 had good internal consistency, along with excellent test-retest and inter-rater reliability. The change in scores of an individual child with CP should attain 9.61 points on the balance subtest of the BOT-2 to indicate a clinically important change. The MDC95 and MCID values could be helpful in understanding therapeutic effects and evaluating balancing ability using the balance subtest of the BOT-2 in children with CP.

Effects of Inspiratory Muscle and Balance Training in Children with Hemiplegic Cerebral Palsy: A Randomized Controlled Trial

The aim of the study was to investigate the effects of inspiratory muscle and balance training on pulmonary function, respiratory muscle strength (RMS), functional capacity, and balance in children with hemiplegic cerebral palsy (CP). Thirty children with hemiplegic CP (Gross Motor Function Classification System I-II) included in this study. The control group (n = 15) underwent conventional physiotherapy rehabilitation program (CPRP) that included balance exercises, and the training group's (n = 15) program included inspiratory muscle training (IMT) in addition to CPRP for 8 weeks. The outcome measures were pulmonary function test, RMS measurement, the six-minute walk test (6MWT), and balance tests. There were no significant differences in the score changes of pulmonary function, balance, and 6MWT distance between groups (p > .05), whereas maximum inspiratory and expiratory pressure further increased in the training group (p > .05). RMS assessment and the identification of children who need it, and adding IMT to CPRP will contribute greatly to the rehabilitative approach of children with CP.

Effectiveness of a Multi-Modal Exercise Program Incorporating Plyometric and Balance Training in Children With Hemiplegic Cerebral Palsy: A Three-Armed Randomized Clinical Trial

AIM

To evaluate the effectiveness of a multimodal exercise program incorporating plyometric and balance training on muscle strength and postural stability in children with spastic hemiplegic cerebral palsy (SHCP).

METHODS

A total of 57 children with SHCP were enrolled in the study and randomly allocated into three treatment-based groups: plyometric exercises (PLYO group; n = 19), balance exercises (BAL group, n = 19), and combined plyometric and balance exercises (PLYO-BAL group; n = 19). The maximum isometric muscle strength (IMS_max) and postural stability [anterior-posterior stability index (AP-SI), mediolateral stability index (ML-SI), and overall stability index (O-SI)] were measured pre- and post-intervention.

RESULTS

By applying the intention-to-treat analysis, the PLYO-BAL group showed greater post-treatment IMS_max than the PLYO and BAL groups for the quadriceps (p=.03 and p=.0002 respectively), hamstrings (p=.018 and p<.0001 respectively), and dorsiflexors (p=.006 and p<.0001 respectively). Also, the PLYO-BAL group achieved better post-intervention stability scores as compared to PLYO and BAL groups regarding AP-SI (p<.0001 and p=.0001 respectively), ML-SI (p=.001 and p=.015 respectively), and O-SI (p=.011 and p=.04 respectively).

CONCLUSIONS

Incorporation of plyometric and balance exercises in a multimodal rehabilitation program could be an important consideration for enhancing muscle strength and boosting postural stability in children with SHCP.

Effect of functional electrical stimulation versus TheraTogs on gait and balance in children with hemiplegic cerebral palsy: a randomized controlled trial

Background

Children with cerebral palsy exhibit postural restrictions and gait problems as a result of both primary and secondary brain damage impairments. One of the main goals of cerebral palsy rehabilitation is to improve gait and balance. As a result, the purpose of this study was to compare the effects of FES and TheraTogs on gait and balance in children with hemiplegic CP. A randomized controlled study was conducted on 30 children with hemiplegic CP (18 boys and 12 girls) between the ages of 8 and 12 years. The children were divided into two equal groups. In addition to the traditional physical treatment program, the FES group received functional electrical stimulation (pulse width 300 μs, frequency 33 Hz, 2 h/day, 3 days/week, 3 months). The TheraTogs group, on the other hand, received the TheraTogs strapping system as well as the same traditional program for the same time period. The 3-D motion analysis and the Biodex balance system were used to analyze gait parameters and postural stability at baseline and 3 months after the intervention.

Results

When comparing the mean values of the gait parameters and postural stability indices of children in both groups before and after treatment, a significant improvement was reported. Furthermore, the FES group showed a greater improvement in all of the measured outcomes (P < 0.001).

Conclusion

Functional electrical stimulation improves gait pattern and postural stability in children with hemiplegic cerebral palsy significantly more than TheraTogs strapping systems.

Efficacy of axial TheraTogs on gait pattern in children with dyskinetic cerebral palsy: a randomized controlled trial

Background

TheraTogs promotes proprioceptive sense of a child with cerebral palsy and improves abnormal muscle tone, posture alignment, balance, and gait. Therefore, the aim of this study was to investigate the efficacy of TheraTogs orthotic undergarment on gait pattern in children with dyskinetic cerebral palsy. Thirty children with dyskinetic cerebral palsy were selected for this randomized controlled study. They were randomly assigned to (1) an experimental group that received TheraTogs orthotic undergarment (12 h/day, 3 days/week) plus traditional physical therapy for 3 successive months and (2) a control group that received only traditional physical therapy program for the same time period. Gait parameters were measured at baseline and after 3 months of intervention using Pro-Reflex motion analysis.

Results

Children in both groups showed significant improvements in the gait parameters (P < 0.05), with significantly greater improvements in the experimental group than in the control group.

Conclusions

The use of TheraTogs may have a positive effect to improve gait pattern in children with dyskinetic cerebral palsy.

Trial registration

This trial was registered in the ClinicalTrial.gov PRS (NCT03037697).

Assessment of spatiotemporal gait parameters using a deep learning algorithm-based markerless motion capture system

Spatiotemporal parameters can characterize the gait patterns of individuals, allowing assessment of their health status and detection of clinically meaningful changes in their gait. Video-based markerless motion capture is a user-friendly, inexpensive, and widely applicable technology that could reduce the barriers to measuring spatiotemporal gait parameters in clinical and more diverse settings. Two studies were performed to determine whether gait parameters measured using markerless motion capture demonstrate concurrent validity with those measured using marker-based motion capture and a pressure-sensitive gait mat. For the first study, thirty healthy young adults performed treadmill gait at self-selected speeds while marker-based motion capture and synchronized video data were recorded simultaneously. For the second study, twenty-five healthy young adults performed over-ground gait at self-selected speeds while footfalls were recorded using a gait mat and synchronized video data were recorded simultaneously. Kinematic heel-strike and toe-off gait events were used to identify the same gait cycles between systems. Nine spatiotemporal gait parameters were measured by each system and directly compared between systems. Measurements were compared using Bland-Altman methods, mean differences, Pearson correlation coefficients, and intraclass correlation coefficients. The results indicate that markerless measurements of spatiotemporal gait parameters have good to excellent agreement with marker-based motion capture and gait mat systems, except for stance time and double limb support time relative to both systems and stride width relative to the gait mat. These findings indicate that markerless motion capture can adequately measure spatiotemporal gait parameters of healthy young adults during treadmill and over-ground gait.

Kinect V2-Based Gait Analysis for Children with Cerebral Palsy: Validity and Reliability of Spatial Margin of Stability and Spatiotemporal Variables

Children with cerebral palsy (CP) have high risks of falling. It is necessary to evaluate gait stability for children with CP. In comparison to traditional motion capture techniques, the Kinect has the potential to be utilised as a cost-effective gait stability assessment tool, ensuring frequent and uninterrupted gait monitoring. To evaluate the validity and reliability of this measurement, in this study, ten children with CP performed two testing sessions, of which gait data were recorded by a Kinect V2 sensor and a referential Motion Analysis system. The margin of stability (MOS) and gait spatiotemporal metrics were examined. For the spatiotemporal parameters, intraclass correlation coefficient (ICC_2,k) values were from 0.83 to 0.99 between two devices and from 0.78 to 0.88 between two testing sessions. For the MOS outcomes, ICC_2,k values ranged from 0.42 to 0.99 between two devices and 0.28 to 0.69 between two test sessions. The Kinect V2 was able to provide valid and reliable spatiotemporal gait parameters, and it could also offer accurate outcome measures for the minimum MOS. The reliability of the Kinect V2 when assessing time-specific MOS variables was limited. The Kinect V2 shows the potential to be used as a cost-effective tool for CP gait stability assessment.

Early balance training with a computerized stabilometric platform in persons with mild hemiparesis in subacute stroke phase: A randomized controlled pilot study

BACKGROUND

Along with conventional therapy, novel tools are being developed in balance training for the rehabilitation of persons with stroke sequelae. The efficacy of Computerized Balance Training thus far been the object of studies only in persons with chronic stroke.

OBJECTIVE

To investigate the effects of an early Computerized Balance Training on balance, walking endurance and independence in activities of daily living, in persons with mild hemiparesis in subacute phase.

METHODS

Thirty-two persons with a recent hemiparesis (within 4 weeks from stroke onset), able to maintain a standing position for at least 30 seconds, were randomly assigned to an experimental or control group. The control group (CG) were administered conventional physiotherapy of 40 minutes twice a day, 5 times a week for 4 weeks, while the experimental group (EG) underwent conventional physiotherapy 40 minutes once a day and Computerized Balance Training once a day, 5 times a week for 4 weeks. Outcomes were evaluated by means of Berg Balance Scale (BBS), Tinetti Balance Scale (TBS), Two Minutes Walk Test (2MWT), Barthel Index (BI) and stabilometric tests.

RESULTS

Twelve participants for each group completed the training. Each group experienced 8 dropouts. The mean age (years) was 58.1±20.4 for EG and 59.7±14,7 for CG; the days from stroke were respectively 27.9±15.5 and 20±11.7. The difference between the two groups was statistically significant in experimental group for BBS (p = 0.003), for TBS (p = 0.028), for Sensory Integration and Balance tests performed with closed eyes on steady (p = 0.009) or instable surface (p = 0.023). and for 2MWT (p = 0.008).

CONCLUSIONS

Computerized Balance Training is an effective therapeutic tool for balance and gait endurance improvement in persons with stroke in subacute phase.

Mucopolysaccharidoses I and II: Brief Review of Therapeutic Options and Supportive/Palliative Therapies

Purpose. Mucopolysaccharidoses (MPS) are group of inherited lysosomal storage diseases caused by mutations of enzymes involved in catalyzing different glycosaminoglycans (GAGs). MPS I and MPS II exhibit both somatic and neurological symptoms with a relatively high disease incidence. Hematopoietic stem cell therapy (HSCT) and intravenous enzyme replacement therapy (ERT) have had a significant impact on the treatment and comprehension of disease. This review is aimed at providing a comprehensive evaluation of the pros and cons of HSCT and ERT, as well as an up-to-date knowledge of new drugs under development. In addition, multiple disease management strategies for the uncontrollable manifestations of MPS I and MPS II to improve patients' quality of life are presented. Findings. Natural history of MPS I and MPS II shows that somatic and neurological symptoms occur earlier in severe forms of MPS I than in MPS II. ERT increases life expectancy and alleviates some of the somatic symptoms, but musculoskeletal, ophthalmological, and central nervous system (CNS) manifestations are not controlled. Additionally, life-long treatment burdens and immunogenicity restriction are unintended consequences of ERT application. HSCT, another treatment method, is effective in controlling the CNS symptoms and hence has been adopted as the standard treatment for severe types of MPS I. However, it is ineffective in MPS II, which can be explained by the relatively late diagnosis. In addition, several factors such as transplant age limits or graft-versus-host disease in HSCT have limited its application for patients. Novel therapies, including BBB-penetrable-ERT, gene therapy, and substrate reduction therapy, are under development to control currently unmanageable manifestations. BBB-penetrable-ERT is being studied comprehensively in the hopes of being used in the near future as a method to effectively control CNS symptoms. Gene therapy has the potential to “cure” the disease with a one-time treatment rather than just alleviate symptoms, which makes it an attractive treatment strategy. Several clinical studies on gene therapy reveal that delivering genes directly into the brain achieves better results than intravenous administration in patients with neurological symptoms. Considering new drugs are still in clinical stage, disease management with close monitoring and supportive/palliative therapy is of great importance for the time being. Proper rehabilitation therapy, including physical and occupational therapy, surgical intervention, or medications, can benefit patients with uncontrolled musculoskeletal, respiratory, ophthalmological, and neurological manifestations.

Slackline Training in Children with Spastic Cerebral Palsy: A Randomized Clinical Trial

Objective: To assess whether a slackline intervention program improves postural control in children/adolescents with spastic cerebral palsy (CP). Design: Randomized controlled trial. Setting: Patients’ association. Participants: Twenty-seven children/adolescents with spastic CP (9–16 years) were randomly assigned to a slackline intervention (n = 14, 13 ± 3 years) or control group (n = 13, 12 ± 2 years). Intervention: Three slackline sessions per week (30 min/session) for 6 weeks. Main outcome measures: The primary outcome was static posturography (center of pressure—CoP—parameters). The secondary outcomes were surface myoelectrical activity of the lower-limb muscles during the posturography test and jump performance (countermovement jump test and Abalakov test). Overall (RPE, >6–20 scale) rating of perceived exertion was recorded at the end of each intervention session. Results: The intervention was perceived as “very light” (RPE = 7.6 ± 0.6). The intervention yielded significant benefits on static posturography (a significant group by time interaction on Xspeed, p = 0.006) and jump performance (a significant group by time interaction on Abalakov test, p = 0.015). Conclusions: Slackline training improved static postural control and motor skills and was perceived as non-fatiguing in children/adolescents with spastic CP.

Combining balance-training interventions with other active interventions may enhance effects on postural control in children and adolescents with cerebral palsy: a systematic review and meta-analysis

BACKGROUND

Improvement of postural control in children and adolescents with cerebral palsy is a primary goal in child rehabilitation.

OBJECTIVE

A systematic review investigated whether combining balance-training interventions with other active interventions enhances the effects of the active intervention alone on postural control of children and adolescents with cerebral palsy.

METHODS

Searches were performed in MEDLINE, PEDro, CINAHL, Cochrane and EMBASE databases without date or language restrictions. Randomized controlled trials investigating the combination of balance-training interventions with other active interventions on the postural control of children and adolescents with cerebral palsy were included. Two independent reviewers screened studies, extracted data, and assessed methodological quality of included studies. Meta-analysis was conducted, and quality of the evidence followed the GRADE methodology. Pooled data were presented using standardized mean difference and 95% confidence interval.

RESULTS

Seven studies involving 194 participants were included in this review. A large additional effect on postural control was found when balance-training interventions were combined with Neurodevelopmental Treatment at short-term (standardized mean difference of 1.3; 95% confidence interval 0.5, 2.0, p=0.001). The quality of the evidence was very low due to publication bias, imprecision and inconsistency.

CONCLUSION

Combining balance-training interventions with other active interventions may enhance effects on postural control of this population at short-term. As the estimated effect had only very low quality of evidence to support it, larger studies with low risk of bias are needed.

Effects of auditovisual feedback on eye-hand coordination in children with cerebral palsy

BACKGROUND

Children with spastic hemiplegic cerebral palsy have deficits in eye-hand coordination. This limits manual actions performed with the affected hand, especially fine motor skills such as grasping and manipulation. Visual-motor integration, grasping skills, and visual perception are collectively involved in eye-hand coordination.

AIMS

We investigated the effects of augmented biofeedback training on eye-hand coordination in children with spastic hemiplegic cerebral palsy.

METHODS AND PROCEDURES

Forty-five spastic hemiplegic cerebral palsy children (5-8 years old) were included. Children were assigned randomly into three equal groups. One group received traditional physical therapy to facilitate visual-motor integration and grasping skills for 3 months. The second group received augmented biofeedback training. The third group received a combination of augmented biofeedback training and traditional physical therapy. Children were evaluated with the Peabody Developmental Motor Scale (2nd edition) (PDMS-2). Treatment sessions were conducted for 60 min, three times a week, for 3 consecutive months.

OUTCOMES AND RESULTS

Children that received augmented biofeedback training alongside traditional physical therapy had significantly improved scores in the Visual-Motor Integration and grasping subtests compared to children that received only one intervention.

CONCLUSIONS AND IMPLICATIONS

Augmented biofeedback training alongside physical therapy improved eye-hand coordination in children with spastic hemiplegic cerebral palsy.

Augmented Biofeedback Training with Physical Therapy Improves Visual-Motor Integration, Visual Perception, and Motor Coordination in Children with Spastic Hemiplegic Cerebral Palsy: A Randomised Control Trial

Aim: The aim of this study is to investigate the efficacy of combining augmented biofeedback training and standard therapy for improving visual-motor integration (VMI), visual perception (VP), and motor coordination (MC) in children with spastic cerebral palsy (CP).Methods: Participants were 45 children, 5-8 years of age, with spastic hemiplegic CP. They were randomized into three groups: group A followed a 3-month specially designed program physical therapy intervention to facilitate VMI and VP. Group B received augmented biofeedback training. Group C received augmented biofeedback training and the physical therapy program provided to group A. The treatment sessions lasted 60 min, three times a week for three months. The Beery-Buktenica Developmental Test of VMI and its supplemental tests were used to evaluate the children before and after the program.Results: After a 3-month treatment, standard scores and age equivalent scores for VMI, VP, and MC were significantly higher in group C compared with group A.Conclusion: The combination of augmented biofeedback and physical therapy could be used to improve VMI, VP, and MC in children with spastic hemiplegic CP.

Gait parameters in children with bilateral spastic cerebral palsy: a systematic review of randomized controlled trials

AIM

To identify the gait parameters used to assess gait disorders in children with bilateral spastic cerebral palsy (CP) and evaluate their responsiveness to treatments.

METHOD

A systematic search within PubMed, Web of Science, and Scopus (in English, 2000-2016) for randomized controlled trials of children with bilateral spastic CP who were assessed by instrumented gait analysis (IGA) was performed. Data related to participants and study characteristics, risk of bias, and outcome measures were collected. A list of gait parameters responsive to clinical interventions was obtained.

RESULTS

Twenty-one articles met the inclusion criteria. Eighty-nine gait parameters were identified, 56 of which showed responsiveness to treatments. Spatiotemporal and kinematic parameters were widely used compared to kinetic and surface electromyography data. The majority of responsive gait parameters were joint angles at the sagittal plane (flexion-extension).

INTERPRETATION

The IGA yields responsive outcome measures for the gait assessment of children with bilateral spastic CP. Spatiotemporal and kinematic (at sagittal plane) parameters are the gait parameters used most frequently. Further research is needed to establish the relevant gait parameters for each clinical problem.

WHAT THIS PAPER ADDS

Fifty-six responsive gait parameters for children with bilateral spastic cerebral palsy were identified. Most responsive gait parameters belong to joint angles time-series at sagittal plane. Spatiotemporal and kinematic parameters are widely used compared to kinetic and surface electromyography parameters.

Estimating the effect size of surgery to improve walking in children with cerebral palsy from retrospective observational clinical data

Single-event multilevel surgery (SEMLS) is a standard treatment approach aimed at improving gait for patients with cerebral palsy, but the effect of this approach compared to natural progression without surgical intervention is unclear. In this study, we used retrospective patient history, physical exam, and three-dimensional gait analysis data from 2,333 limbs to build regression models estimating the effect of SEMLS on gait, while controlling for expected natural progression. Post-hoc classifications using the regression model results identified which limbs would exhibit gait within two standard deviations of typical gait at the follow-up visit with or without a SEMLS with 73% and 77% accuracy, respectively. Using these models, we found that, while surgery was expected to have a positive effect on 93% of limbs compared to natural progression, in only 37% of limbs was this expected effect a clinically meaningful improvement. We identified 26% of the non-surgically treated limbs that may have shown a clinically meaningful improvement in gait had they received surgery. Our models suggest that pre-operative physical therapy focused on improving biomechanical characteristics, such as walking speed and strength, may improve likelihood of positive surgical outcomes. These models are shared with the community to use as an evaluation tool when considering whether or not a patient should undergo a SEMLS.

Effects of Antigravity Treadmill Training on Gait, Balance, and Fall Risk in Children With Diplegic Cerebral Palsy

OBJECTIVE

The aim of this study was to investigate the effects of antigravity treadmill training on gait, balance, and fall risk in children with diplegic cerebral palsy.

DESIGN

Thirty children with diplegic cerebral palsy were selected for this randomized controlled study. They were randomly assigned to (1) an experimental group that received antigravity treadmill training (20 mins/d, 3 d/wk) together with traditional physical therapy for 3 successive mos and (2) a control group that received only traditional physical therapy program for the same period. Outcomes included selected gait parameters, postural stability, and fall risk. Outcomes were measured at baseline and after 3 mos of intervention.

RESULTS

Children in both groups showed significant improvements in the mean values of all measured variables (P < 0.05), with significantly greater improvements in the experimental group than the control group. The posttreatment gait parameters (i.e., velocity, stride length, cadence, and percent of time spent in double-limb support) were 0.74 m/sec, 119 steps/min, 0.75 m/sec, 0.65 sec, and 55.9% as well as 0.5 m, 125 steps/min, 0.6 m/sec, 0.49 sec, and 50.4% for the experimental and control group, respectively.

CONCLUSIONS

Antigravity treadmill training may be a useful tool for improving gait parameters, balance, and fall risk in children with diplegic cerebral palsy.

Exercise interventions for cerebral palsy

BACKGROUND

Cerebral palsy (CP) is a neurodevelopmental disorder resulting from an injury to the developing brain. It is the most common form of childhood disability with prevalence rates of between 1.5 and 3.8 per 1000 births reported worldwide. The primary impairments associated with CP include reduced muscle strength and reduced cardiorespiratory fitness, resulting in difficulties performing activities such as dressing, walking and negotiating stairs.Exercise is defined as a planned, structured and repetitive activity that aims to improve fitness, and it is a commonly used intervention for people with CP. Aerobic and resistance training may improve activity (i.e. the ability to execute a task) and participation (i.e. involvement in a life situation) through their impact on the primary impairments of CP. However, to date, there has been no comprehensive review of exercise interventions for people with CP.

OBJECTIVES

To assess the effects of exercise interventions in people with CP, primarily in terms of activity, participation and quality of life. Secondary outcomes assessed body functions and body structures. Comparators of interest were no treatment, usual care or an alternative type of exercise intervention.

SEARCH METHODS

In June 2016 we searched CENTRAL, MEDLINE, Embase, nine other databases and four trials registers.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs of children, adolescents and adults with CP. We included studies of aerobic exercise, resistance training, and 'mixed training' (a combination of at least two of aerobic exercise, resistance training and anaerobic training).

DATA COLLECTION AND ANALYSIS

Two review authors independently screened titles, abstracts and potentially relevant full-text reports for eligibility; extracted all relevant data and conducted 'Risk of bias' and GRADE assessments.

MAIN RESULTS

We included 29 trials (926 participants); 27 included children and adolescents up to the age of 19 years, three included adolescents and young adults (10 to 22 years), and one included adults over 20 years. Males constituted 53% of the sample. Five trials were conducted in the USA; four in Australia; two in Egypt, Korea, Saudi Arabia, Taiwan, the Netherlands, and the UK; three in Greece; and one apiece in India, Italy, Norway, and South Africa.Twenty-six trials included people with spastic CP only; three trials included children and adolescents with spastic and other types of CP. Twenty-one trials included people who were able to walk with or without assistive devices, four trials also included people who used wheeled mobility devices in most settings, and one trial included people who used wheeled mobility devices only. Three trials did not report the functional ability of participants. Only two trials reported participants' manual ability. Eight studies compared aerobic exercise to usual care, while 15 compared resistance training and 4 compared mixed training to usual care or no treatment. Two trials compared aerobic exercise to resistance training. We judged all trials to be at high risk of bias overall.We found low-quality evidence that aerobic exercise improves gross motor function in the short term (standardised mean difference (SMD) 0.53, 95% confidence interval (CI) 0.02 to 1.04, N = 65, 3 studies) and intermediate term (mean difference (MD) 12.96%, 95% CI 0.52% to 25.40%, N = 12, 1 study). Aerobic exercise does not improve gait speed in the short term (MD 0.09 m/s, 95% CI -0.11 m/s to 0.28 m/s, N = 82, 4 studies, very low-quality evidence) or intermediate term (MD -0.17 m/s, 95% CI -0.59 m/s to 0.24 m/s, N = 12, 1 study, low-quality evidence). No trial assessed participation or quality of life following aerobic exercise.We found low-quality evidence that resistance training does not improve gross motor function (SMD 0.12, 95% CI -0.19 to 0.43, N = 164, 7 studies), gait speed (MD 0.03 m/s, 95% CI -0.02 m/s to 0.07 m/s, N = 185, 8 studies), participation (SMD 0.34, 95% CI -0.01 to 0.70, N = 127, 2 studies) or parent-reported quality of life (MD 12.70, 95% CI -5.63 to 31.03, n = 12, 1 study) in the short term. There is also low-quality evidence that resistance training does not improve gait speed (MD -0.03 m/s, 95% CI -0.17 m/s to 0.11 m/s, N = 84, 3 studies), gross motor function (SMD 0.13, 95% CI -0.30 to 0.55, N = 85, 3 studies) or participation (MD 0.37, 95% CI -6.61 to 7.35, N = 36, 1 study) in the intermediate term.We found low-quality evidence that mixed training does not improve gross motor function (SMD 0.02, 95% CI -0.29 to 0.33, N = 163, 4 studies) or gait speed (MD 0.10 m/s, -0.07 m/s to 0.27 m/s, N = 58, 1 study) but does improve participation (MD 0.40, 95% CI 0.13 to 0.67, N = 65, 1 study) in the short-term.There is no difference between resistance training and aerobic exercise in terms of the effect on gross motor function in the short term (SMD 0.02, 95% CI -0.50 to 0.55, N = 56, 2 studies, low-quality evidence).Thirteen trials did not report adverse events, seven reported no adverse events, and nine reported non-serious adverse events.

AUTHORS' CONCLUSIONS

The quality of evidence for all conclusions is low to very low. As included trials have small sample sizes, heterogeneity may be underestimated, resulting in considerable uncertainty relating to effect estimates. For children with CP, there is evidence that aerobic exercise may result in a small improvement in gross motor function, though it does not improve gait speed. There is evidence that resistance training does not improve gait speed, gross motor function, participation or quality of life among children with CP.Based on the evidence available, exercise appears to be safe for people with CP; only 55% of trials, however, reported adverse events or stated that they monitored adverse events. There is a need for large, high-quality, well-reported RCTs that assess the effectiveness of exercise in terms of activity and participation, before drawing any firm conclusions on the effectiveness of exercise for people with CP. Research is also required to determine if current exercise guidelines for the general population are effective and feasible for people with CP.

Locomotor training through a novel robotic platform for gait rehabilitation in pediatric population: short report

BACKGROUND

Cerebral Palsy (CP) is a disorder of posture and movement due to a defect in the immature brain. The use of robotic devices as alternative treatment to improve the gait function in patients with CP has increased. Nevertheless, current gait trainers are focused on controlling complete joint trajectories, avoiding postural control and the adaptation of the therapy to a specific patient. This paper presents the applicability of a new robotic platform called CPWalker in children with spastic diplegia.

FINDINGS

CPWalker consists of a smart walker with body weight and autonomous locomotion support and an exoskeleton for joint motion support. Likewise, CPWalker enables strategies to improve postural control during walking. The integrated robotic platform provides means for testing novel gait rehabilitation therapies in subjects with CP and similar motor disorders. Patient-tailored therapies were programmed in the device for its evaluation in three children with spastic diplegia for 5 weeks. After ten sessions of personalized training with CPWalker, the children improved the mean velocity (51.94 ± 41.97 %), cadence (29.19 ± 33.36 %) and step length (26.49 ± 19.58 %) in each leg. Post-3D gait assessments provided kinematic outcomes closer to normal values than Pre-3D assessments.

CONCLUSIONS

The results show the potential of the novel robotic platform to serve as a rehabilitation tool. The autonomous locomotion and impedance control enhanced the children's participation during therapies. Moreover, participants' postural control was substantially improved, which indicates the usefulness of the approach based on promoting the patient's trunk control while the locomotion therapy is executed. Although results are promising, further studies with bigger sample size are required.

An ecological evaluation of the metabolic benefits due to robot-assisted gait training

Cerebral palsy (CP), one of the most common neurological disorders in childhood, features affected individual's motor skills and muscle actions. This results in elevated heart rate and rate of oxygen uptake during sub-maximal exercise, thus indicating a mean energy expenditure higher than healthy subjects. Rehabilitation, currently involving also robot-based devices, may have an impact also on these aspects. In this study, an ecological setting has been proposed to evaluate the energy expenditure of 4 children with CP before and after a robot-assisted gait training. Even if the small sample size makes it difficult to give general indications, results presented here are promising. Indeed, children showed an increasing trend of the energy expenditure per minute and a decreasing trend of the energy expenditure per step, in accordance to the control group. These data suggest a metabolic benefit of the treatment that may increase the locomotion efficiency of disabled children.

The Effect of Training on Postural Control in Dyslexic Children

The aim of this study was to explore whether a short postural training period could affect postural stability in dyslexic children. Postural performances were evaluated using Multitest Equilibre from Framiral. Posture was recorded in three different viewing conditions (eyes open fixating a target, eyes closed and eyes open with perturbed vision) and in two different postural conditions (on stable and unstable support). Two groups of dyslexic children participated in the study, i.e. G1: 16 dyslexic participants (mean age 9.9 ± 0.3 years) who performed short postural training and G2: 16 dyslexic participants of similar ages (mean age 9.1 ± 0.3 years) who did not perform any short postural training. Findings showed that short postural training improved postural stability on unstable support surfaces with perturbed vision: indeed the surface, the mean velocity of CoP and the spectral power indices in both directions decreased significantly, and the cancelling time in the antero-posterior direction improved significantly. Such improvement could be due to brain plasticity, which allows better performance in sensory process and cerebellar integration.
