OBJECTIVETo study the effect of suspension exercise training on motor and balance functions in children with spastic cerebral palsy.

METHODSA total of 97 children with spastic cerebral palsy were randomly divided into an observation group with 49 children and a control group with 48 children. Both groups were given routine rehabilitation training, and the children in the observation group were given suspension exercise training in addition. The scores of the D and E domains of the 88-item version of the Gross Motor Function Measure (GMFM-88) and Berg Balance Scale (BBS) were recorded before treatment and at 1, 3, and 6 months after treatment. Surface electromyography was performed to observe the changes in the root mean square (RMS) of surface electromyogram signals of the adductor muscle and the gastrocnemius muscle.

RESULTSOver the time of treatment, both groups had varying degrees of improvement in the scores of the D and E domains of GMFM-88 and BBS. Compared with the control group, the observation group had significantly greater improvements in D and E functional areas and balance function (P<0.05). Both groups had reductions in the RMS of the surface electromyogram signals of the adductor muscle and the gastrocnemius muscle over the time of treatment, and the observation group had significantly greater reductions than the control group (P<0.05).

CONCLUSIONSSuspension exercise training can effectively improve the motor and balance functions of children with spastic cerebral palsy.

OBJECTIVE: To propose a kind of robotic ankle-foot rehabilitation system for children with cerebral palsy and to preliminarily verify its feasibility in clinical application. METHODS: A robot assisted ankle-foot rehabilitation system was specially designed and developed for children with cerebral palsy and a preliminary clinical study was conducted in Department of Rehabilitation Medicine, Peking University First Hospital. Modified Tardieu Scale and joint biomechanical properties (ankle plantar flexion resistance torque under different ankle dorsiflexion angles) were measured to analyze the muscle tone and soft tissue compliance of the ankle plantar flexors pre- and post-robotic training intervention. Six children with cerebral palsy (4 girls and 2 boys, mean age: 7 years) were recruited in this study. Each subject received 5 session robotic training and each session included 10-cycle passive stretching and static hold. SPSS 19.0 software was used for data statistical analysis. RESULTS: Both R1 and R2 angles of Modified Tardieu Scale for ankle plantar flexors after training were significantly higher than those before the treatments (Gastrocnemius: P_R1=0.003, P_R2=0.029; Soleus: P_R1=0.002, P_R2=0.034). The difference between R2 and R1 was of no statistical difference before and after the training (P=0.067 and P=0.067, respectively). After training, the ankle plantar flexion resistance torque under different dorsiflexion angles (0°, 10°, 20°, 30°) were significantly reduced than those before training (P=0.001, P=0.001, P=0.014, P=0.002, respectively). CONCLUSION The robot assisted ankle-foot rehabilitation system can improve the contracture and soft tissue compliance of cerebral palsy children's ankle plantar flexors. All the children in the study were well tolerated and interested with the training, easy to accept and cooperate with it. This device may be suitable for application in the rehabilitation of children with cerebral palsy. However, further randomized clinical trials with larger sample size are still needed to verify the long term efficacy of this device.

OBJECTIVETo investigate the long-term clinical efficacy and adverse effects of botulinum toxin-A (BTX-A) injection in the treatment of gastrocnemius spasticity in children aged 9-36 months with cerebral palsy.

METHODSEighty children aged 9-36 months with cerebral palsy and gastrocnemius spasticity were selected and randomly divided into a BTX-A injection group and a conventional treatment group (n=40 each). The children in the BTX-A injection group received injections of BTX-A guided by color Doppler ultrasound and 4 courses of rehabilitation training after injection. Those in the conventional treatment group received 4 courses of the same rehabilitation training alone. Before treatment and at 1, 2, 3, and 6 months after treatment, the modified Tardieu scale (MTS) was applied to assess the degree of gastrocnemius spasticity, the values in the passive state measured by surface electromyography (sEMG) were applied to evaluate muscle tension, and the Gross Motor Function Measure (GMFM) was used to evaluate gross motor function.

RESULTSCompared with the conventional treatment group, the BTX-A injection group had significantly greater reductions in MTS score and the values in the passive state measured by sEMG (P<0.05), as well as significantly greater increases in joint angles R1 and R2 in MTS and gross motor score in GMFM (P<0.05). No serious adverse reactions related to BTX-A injection were found.

CONCLUSIONSBTX-A injection is effective and safe in the treatment of gastrocnemius spasticity in children aged 9-36 months with cerebral palsy.

PURPOSE: To investigate the effect of intramuscular Botulinum toxin type A (BoNT-A) injection on gait and dynamic foot pressure distribution in children with spastic cerebral palsy (CP) with dynamic equinovarus foot. MATERIALS AND METHODS: Twenty-five legs of 25 children with CP were investigated in this study. BoNT-A was injected into the gastrocnemius (GCM) and tibialis posterior (TP) muscles under the guidance of ultrasonography. The effects of the toxin were clinically assessed using the modified Ashworth scale (MAS) and modified Tardieu scale (MTS), and a computerized gait analysis and dynamic foot pressure measurements using the F-scan system were also performed before injection and at 1 and 4 months after injection. RESULTS: Spasticity of the ankle plantar-flexor in both the MAS and MTS was significantly reduced at both 1 and 4 months after injection. On dynamic foot pressure measurements, the center of pressure index and coronal index, which represent the asymmetrical weight-bearing of the medial and lateral columns of the foot, significantly improved at both 1 and 4 months after injection. The dynamic foot pressure index, total contact area, contact length and hind foot contact width all increased at 1 month after injection, suggesting better heel contact. Ankle kinematic data were significantly improved at both 1 and 4 months after injection, and ankle power generation was significantly increased at 4 months after injection compared to baseline data. CONCLUSION: Using a computerized gait analysis and foot scan, this study revealed significant benefits of BoNT-A injection into the GCM and TP muscles for dynamic equinovarus foot in children with spastic CP.

PURPOSE: The aim of this study was to investigate the effect of incentive spirometer exercise (ISE) on pulmonary function and maximal phonation time (MPT) in children with spastic cerebral palsy (CP). MATERIALS AND METHODS: Fifty children with CP were randomly assigned to two groups: the experimental group and the control group. Both groups underwent comprehensive rehabilitation therapy. The experimental group underwent additional ISE. The forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC ratio, peak expiratory flow (PEF), and MPT were assessed as outcome measures before and after 4 weeks of training. RESULTS: There were significant improvements in FVC, FEV1, PEF, and MPT in the experimental group, but not in the control group. In addition, the improvements in FVC, FEV1, and MPT were significantly greater in the experimental group than in the control group. CONCLUSION: The results of this randomized controlled study support the use of ISE for enhancing pulmonary function and breath control for speech production in children with CP.

PURPOSE: This study investigated the correlation between isometric muscle strength, gross motor function, and gait parameters in patients with spastic cerebral palsy and to find which muscle groups play an important role for gait pattern in a flexed knee gait. MATERIALS AND METHODS: Twenty-four ambulatory patients (mean age, 10.0 years) with spastic cerebral palsy who were scheduled for single event multilevel surgery, including distal hamstring lengthening, were included. Preoperatively, peak isometric muscle strength was measured for the hip flexor, hip extensor, knee flexor, and knee extensor muscle groups using a handheld dynamometer, and three-dimensional (3D) gait analysis and gross motor function measure (GMFM) scoring were also performed. Correlations between peak isometric strength and GMFM, gait kinematics, and gait kinetics were analyzed. RESULTS: Peak isometric muscle strength of all muscle groups was not related to the GMFM score and the gross motor function classification system level. Peak isometric strength of the hip extensor and knee extensor was significantly correlated with the mean pelvic tilt (r=-0.588, p=0.003 and r=-0.436, p=0.033) and maximum pelvic obliquity (r=-0.450, p=0.031 and r=-0.419, p=0.041). There were significant correlations between peak isometric strength of the knee extensor and peak knee extensor moment in early stance (r=0.467, p=0.021) and in terminal stance (r=0.416, p=0.043). CONCLUSION: There is no correlation between muscle strength and gross motor function. However, this study showed that muscle strength, especially of the extensor muscle group of the hip and knee joints, might play a critical role in gait by stabilizing pelvic motion and decreasing energy consumption in a flexed knee gait.

OBJECTIVETo study the effects of virtual reality (VR) training on the gross motor function of the lower limb and the fine motor function of the upper limb in children with spastic diplegia cerebral palsy.

METHODSThirty-five children with spastic diplegia cerebral palsy were randomly assigned to VR training group (n=19) and conventional training group (n=16). The conventional training group received conventional physical therapy and occupational therapy for three months. The VR training group received VR training and occupational therapy for three months. Grip and visual-motor integration subtests in Peabody Developmental Motor Scales-2 were used to evaluate the fine movement in patients before and after treatment. The D and E domains of the 88-item version of the Gross Motor Function Measure (GMFM-88), Modified Ashworth Scale (MAS), and Berg Balance Scale (BBS) were used to evaluate the gross movement in patients before and after treatment.

RESULTSBefore treatment, there were no significant differences in grip, visual-motor integration, fine motor development quotient, scores of D and E domains of GMFM-88, MAS score, or BBS score between the two groups (P>0.05). After treatment, all the indices were significantly improved in the VR training group compared with the conventional training group (P<0.05).

CONCLUSIONSVR training can effectively improve the gross motor function of the lower limb and the fine motor function of the upper limb in children with spastic diplegia cerebral palsy.

PURPOSE: The purpose of our study was to investigate the effect of gait training with rhythmic auditory stimulation (RAS) on both kinematic and temporospatial gait patterns in patients with hemiplegia. MATERIALS AND METHODS: Eighteen hemiplegic patients diagnosed with either cerebral palsy or stroke participated in this study. All participants underwent the 4-week gait training with RAS. The treatment was performed for 30 minutes per each session, three sessions per week. RAS was provided with rhythmic beats using a chord progression on a keyboard. Kinematic and temporospatial data were collected and analyzed using a three-dimensional motion analysis system. RESULTS: Gait training with RAS significantly improved both proximal and distal joint kinematic patterns in hip adduction, knee flexion, and ankle plantar flexion, enhancing the gait deviation index (GDI) as well as ameliorating temporal asymmetry of the stance and swing phases in patients with hemiplegia. Stroke patients with previous walking experience demonstrated significant kinematic improvement in knee flexion in mid-swing and ankle dorsiflexion in terminal stance. Among stroke patients, subacute patients showed a significantly increased GDI score compared with chronic patients. In addition, household ambulators showed a significant effect on reducing anterior tilt of the pelvis with an enhanced GDI score, while community ambulators significantly increased knee flexion in mid-swing phase and ankle dorsiflexion in terminal stance phase. CONCLUSION: Gait training with RAS has beneficial effects on both kinematic and temporospatial patterns in patients with hemiplegia, providing not only clinical implications of locomotor rehabilitation with goal-oriented external feedback using RAS but also differential effects according to ambulatory function.

OBJECTIVETo explore the effective therapeutic method for reducing adductor muscle tension in the children of spasmodic cerebral palsy.

METHODSOne hundred and forty cases of spasmodic cerebral palsy met the inclusive criteria were randomized into an observation group and a control group, 70 cases in each one. In the control group, the conventional physical therapies (Bobath therapy and lower extremities therapy) and scalp acupuncture (seven-intelligent needles, motor area, sensory area, foot-motor-sensory area and balance area) were adopted. In the observation group, on the basis of the treatment as the control group, the three-spasm-needle therapy was applied to Jiejian, Xuehaishang and Houxuehai. The physical therapies were given once every day, acupuncture was given once every two days, the treatment of 20 days made one session. There were 15 to 20 days at the interval among the sessions and 3 sessions were required totally. Separately before and after treatment, the modified Ashworth scale was used to evaluate the adductor muscle tension, and measure the adductor muscle angle, and D and E regions of gross motor function measure (GMFM-88) were adopted for clinical efficacy evaluation.

RESULTSAfter treatment, the scores of the adductor muscle tension were decreased to different extends in the two groups (both P<0.01), the adductor muscle angle was increased as compared with that before treatment (both P<0.01) and the scores of D and F regions in GMFM-88 were all improved (all P<0.01). The efficacy in the observation group was more significant than that in the control group (all P<0.01).

CONCLUSIONThe three-spasm-needle therapy effectively reduces adductor muscle tension and improves the range of motion in hip joint, independent walking, running and jumping abilities in the children of spasmodic cerebral palsy.
