Acupuncture and Tuina Treatment for Gross Motor Function in Children with Spastic Cerebral Palsy: A Monocentric Clinical Study

Objective

Cerebral palsy (CP) is a condition characterized by abnormal pronunciation, posture, and movement, particularly spastic CP, which involves Gross motor dysfunction due to increased muscle tone and stiffness. This monocentric clinical study aims to evaluate the effectiveness of acupuncture and tuina (AT) in improving gross motor function and alleviating associated symptoms in children diagnosed with spastic CP.

Methods

A total of 83 eligible patients received AT treatment, while 85 patients received conventional rehabilitation treatment. Both groups underwent a 12-week treatment period following the research protocol. Pre- and post-treatment assessments included the Modified Ashworth Muscle Tension Scale (MAS), Gross Motor Function Measure (GMFM-D and GMFM-E), 6-min walking distance measurement (6MWD), and Modified Children's Functional Independence Rating Scale (WeeFIM).

Results

After 12 weeks of treatment, when compared with baseline, the scores of MAS in both AT group and control group are decreased (p<0.01, p<0.01), the scores of GMFM-D, GMFME, 6MWD, WeeFIM in both group are increased (p<0.01 in all indicators). When compared with control group, AT group had significantly lower MAS scores compared to the control group (p<0.01), indicating reduced muscle tension. Moreover, AT group showed significantly higher scores in GMFM-D, GMFM-E, 6MWD, and WeeFIM compared to the control group (p<0.01 in all indicators), indicating improved gross motor function and functional independence. The study also revealed an inverse correlation between the children's age and treatment efficacy (r= -0.496, p<0.01 in AT group, r=-0.540, p<0.01 in control group), highlighting the importance of early intervention in the management of CP in children.

Conclusion

These findings suggest that AT may effectively enhance gross motor function and alleviate associated symptoms in children diagnosed with spastic CP. Moreover, early initiation of treatment is crucial to maximize therapeutic efficacy in children with spastic CP.

Motor function and fALFF modulation in convalescent-period ischemic stroke patients after scalp acupuncture therapy: a multi-centre randomized controlled trial

BACKGROUND

Scalp acupuncture has been found to be effective at improving motor function after ischemic stroke, but few studies examining its central mechanisms of action have been carried out. The aim of this study was to investigate the clinical effects of scalp acupuncture on motor dysfunction and changes in spontaneous brain activity in patients with ischemic stroke.

METHODS

This was an evaluator- and analyst-blinded, multi-center randomized controlled trial. A total of 108 convalescent-stage ischemic stroke patients with motor dysfunction were allocated to receive either scalp acupuncture combined with rehabilitation treatment (SR group) or rehabilitation treatment alone (RE group). Patients in both groups received treatment 5 times per week for 8 weeks. The primary outcome measure was the Fugl-Meyer assessment (FMA). Secondary outcome measures included the modified Barthel index (mBI), modified Rankin scale (mRS) and values of fractional amplitude of low frequency fluctuation (fALFF) acquired using a resting-state functional magnetic resonance imaging (rs-fMRI) technique.

RESULTS

Both groups showed significant improvements in motor function, daily life ability and degree of disability, as measured by FMA, mRS and mBI (p < 0.05), and the SR group showed a significantly greater improvement (p < 0.05). Compared with the RE group, the areas where the fALFF values increased in the SR group were located in the cerebellum, praecuneus, precentral gyrus, superior frontal gyrus and parietal lobe. The improvement in FMA scores had the strongest correlation with the baseline fALFF values of the ipsilateral precentral gyrus.

CONCLUSION

Scalp acupuncture improved motor function in convalescent-period ischemic stroke patients, and effects were correlated with regulation of motor-relevant brain regions. The fALFF value of the ipsilateral precentral and postcentral gyri could be potential clinical indices for prognostication of motor dysfunction.

Scalp acupuncture enhances local brain regions functional activities and functional connections between cerebral hemispheres in acute ischemic stroke patients

This study aimed to explore the changes in functional connections between cerebral hemispheres and local brain regions functional activities in patients with acute ischemic stroke (AIS) treated with International Standard Scalp Acupuncture (ISSA). Thirty patients with middle cerebral artery AIS in the dominant hemisphere were selected and randomly divided into two groups such as the control group and the scalp acupuncture group, with 15 patients in each group. Patients in the control group were treated with conventional Western medicine, while patients in the scalp acupuncture group received ISSA (acupuncture at the parietal midline [MS5], acupuncture at the left anterior parietotemporal oblique line [MS6] and acupuncture at the left posterior parietotemporal oblique line [MS7]) for one course of treatment. All patients were evaluated for treatment efficacy and received whole brain resting state functional magnetic resonance imaging (Rs‐fMRI) scan before and after treatment. The observational indicators included: (a) the National Institutes of Health Stroke Scale (NIHSS) scores and the simplified Fugl‐Meyer Assessment (SFMA) scores; (b) analyses of the amplitude of low‐frequency fluctuation (ALFF), regional homogeneity (ReHo) and voxel‐mirrored homotopic connectivity (VMHC). The results showed a significant difference in the NIHSS scores before and after treatment in the scalp acupuncture group compared with the control group (p < .05), indicating that patients improved better after scalp acupuncture treatment. Compared with the control group, the VMHC, ALFF and ReHo values in the scalp acupuncture group increased after treatment. The VMHC values increased in the brain regions dominated by bilateral BA6 and BA8; the ALFF values increased in the left BA39 and the adjacent superior temporal gyrus and middle temporal gyrus; and the ReHo values increased in the brain regions extending from left middle temporal gyrus (including BA21) to BA37, and the brain regions extending from the left BA40 and angular gyrus to BA7. The present study indicated that scalp acupuncture can specifically strengthen the functional activities of the brain regions related to sensory integration, language processing and motor coordination in the middle aged and elderly patients with AIS of the dominant cerebral hemisphere, and can strengthen bilateral frontal lobe motor control. This study may provide a scientific basis for the clinical application of ISSA treatment in patients with AIS, and may also provide a preliminary research basis for further animal experiments.

Acupuncture treatment on the motor area of the scalp for motor dysfunction in children with cerebral palsy: study protocol for a multicenter randomized controlled trial

Background

Scalp acupuncture has been widely used as treatment for motor dysfunction in children with cerebral palsy in China. Previous studies have failed to provide high-quality evidence to demonstrate the effectiveness of this treatment in children with cerebral palsy. No high-quality randomized controlled trials on scalp acupuncture have been published. The aim of this study is to evaluate the effectiveness of Jiao’s scalp acupuncture when combined with routine rehabilitation treatment versus routine rehabilitation treatment alone for motor dysfunction in children with cerebral palsy.

Methods/Design

This is a four-centre randomized controlled trial. One hundred cerebral palsy patients with motor dysfunction were enrolled. Patients will be allocated in a 1:1 ratio into either an acupuncture treatment group or a control group. Cerebral palsy patients in the control group will receive conventional rehabilitation treatment, whereas patients in the acupuncture group will receive a combination of scalp acupuncture and conventional rehabilitation treatment. Thirty-six treatment sessions will be performed over a 12-week period. The Gross Motor Function Measure and the Fine Motor Function Measure Scale will be assessed as the primary outcome measures. The Paediatric Evaluation of Disability Inventory and the Cerebral Palsy Quality of Life Questionnaire for Children will be selected as secondary outcome measures. All assessments will be conducted at baseline, week 4 (treatment 12), week 8 (treatment 24), week 12 (treatment 36) and week 24 (follow-up).

Discussion

This is the first trial evaluating the efficacy and safety of scalp acupuncture as a treatment for motor dysfunction in children with cerebral palsy. The results of this trial are expected to provide relevant evidence demonstrating that scalp acupuncture can be used as an effective rehabilitation treatment method for improving motor dysfunction in children with cerebral palsy.

Immediate relief of herniated lumbar disc-related sciatica by ankle acupuncture: A study protocol for a randomized controlled clinical trial

BACKGROUND

Around 90% of sciatica cases are due to a herniated intervertebral disc in the lumbar region. Ankle acupuncture (AA) has been reported to be effective in the treatment of acute nonspecific low back pain. This study aims to evaluate the efficacy of a single session of ankle acupuncture for disc-related sciatica.

METHOD

This will be a double-blinded, randomized controlled clinical trial. Patients diagnosed with disc-related sciatica will be randomly divided into 3 parallel groups. The treatment group (n = 30) will receive ankle acupuncture. The 2 control groups will either undergo traditional needle manipulation (n = 30) or sham acupuncture (n = 30) at the same point as the treatment group. The primary outcome will be pain intensity on a visual analog scale (VAS). The secondary outcomes will be paresthesia intensity on a VAS and the Abbreviated Acceptability Rating Profile (AAPR). The success of blinding will be evaluated, and the needle-induced sensation and adverse events will be recorded. All outcomes will be evaluated before, during, and after the treatment.

DISCUSSION

This study will determine the immediate effect and specificity of ankle acupuncture for the treatment of disc-related sciatica. We anticipate that ankle acupuncture might be more effective than traditional needle manipulation or sham acupuncture.
