A bibliometric analysis of cerebral palsy from 2003 to 2022

Purpose

This bibliometric study explores cerebral palsy (CP) research from 2003 to 2022 to reveal the topic hotspots and collaborations.

Methods

We retrieved studies on CP from the Web of Science Core Collection from 2003 to 2022 and then used CiteSpace and Bibliometrix to perform a bibliometric analysis and attain knowledge mapping, including publication outputs, funding, journals, authors, institutions, countries/territories, keywords, collaborative relationships, and topic hotspots.

Results

In total, 8,223 articles were published from 2003 to 2022. During this period, the number of publications increased continuously. Developmental Medicine and Child Neurology was the most productive and frequently co-cited journal. Boyd was the most productive and influential author, with 143 publications and 4,011 citations. The United States and Vrije Universiteit Amsterdam were the most productive countries and institutions, respectively. Researchers and institutions from the USA, Australia, and Canada constituted the core research forces, with extensive collaborations worldwide. The most common keywords were gait (553), rehabilitation (440), spasticity (325), botulinum toxin (174), therapy (148), upper extremity (141), quality of life (140), disability (115), pain (98), electromyography (97), kinematics (90), balance (88), participation (85), and walking (79).

Conclusion

This study provides a systematic and comprehensive analysis of the CP-related literature. It reveals that Developmental Medicine and Child Neurology is the most active journal in this field. The USA, Vrije Universiteit Amsterdam, and Boyd are the top countries, institutions, and authors, respectively. Emerging treatment methods, complication management, and functional recovery comprise the future research directions and potential topic hotspots for CP.

KINEMATIC COMPARISON OF ORTHOPEDIC SHOES AND ANKLE-FOOT ORTHOSES IN CHILDREN WITH CEREBRAL PALSY

Introduction Cerebral palsy (CP) patients may have additional complications such as deformities of lower limbs which significantly change the gait pattern. Various treatments have been used to correct the walking gait and among them are orthotic devices. According to the data based on literature research the ankle-foot orthoses (AFOs) are the most widely used in clinical practice for CP patients. However, orthopedic shoes are more widely used in Russia and there is a lack of gait comparison research has been done up to date. Aim. Kinematic data comparison of walking gait between orthopedic shoes and AFOs in children with CP. Materials and methods. Eighteen CP children with GMFCS 2 and GMFCS 3 were recruited for this research. Three test comparisons were conducted for barefoot, orthopedic shoes, and AFOs walking for each children being tested. Twelve Miqus M5 Qualisys cameras were used for kinematic data collection with 100 Hz frequency. Visual3D (C-Motion), Clinical Gait PAF (Qualisys), Statistica 10, and Excel were used for data analysis. Results. The results demonstrated that wearing AFOs versus barefoot improved spatial-temporal parameters as well as ankle and knee joint kinematics without significant changes in hip joint angles for both GMFCS 2 and GMFCS 3 levels. As a result, the Gait Profile Score (GPS) showed significant improvement in AFOs as well. The use of orthopedic footwear in patients with gross motor function levels GMFCS 2 and GMFCS 3 led to improvement of ankle and knee joints kinematics when compared to barefoot walking. However, the group with GMFCS 2 demonstrated less improvement of the ankle and knee joint angles in orthopedic shoes but the GPS showed significantly better overall values when compared to GMFCS 3 group. Therefore, this study showed that orthopedic footwear and AFOs almost equally corrected the walking gait in GMFCS 2 group but AFOs were significantly better for GMFCS 3 group.

Use of lower extremity orthoses in patients with cerebral palsy and related factors

BACKGROUND

The purpose of this study was to investigate the frequency of using lower extremity orthosis prescribed for patients with cerebral palsy (CP) and to determine the factors associated with orthosis use.

STUDY DESIGN

The study had a retrospective and descriptive design.

METHODS

One hundred and twenty-nine patients with CP who were prescribed orthoses were included in this study. The sociodemographic data and orthosis use status of patients were questioned with telephone calls. Motor functions were evaluated with Gross Motor Function Classification System (GMFCS). Spasticity was evaluated with the modified Ashworth scale, and range of motion was evaluated by goniometry. The study had a retrospective and descriptive design and included 129 patients with CP (53 females and 76 males) who were prescribed orthosis. The sociodemographic data and orthosis use status of patients were questioned with telephone calls. Motor functions were evaluated with Gross Motor Function Classification System (GMFCS). Spasticity was evaluated with the modified Ashworth scale, and range of motion was evaluated by goniometry.

RESULTS

A total of 53 patients who were included in the study were female, and 76 were male. The most commonly used orthosis was Ankle-Foot Orthosis. The number of patients who used orthosis every day was 45 (34.8%). The most common reason for not using orthosis was difficulty in wearing it. The mean age was significantly lower in the group that used orthosis regularly (P < 0.05). Spasticity and range of motion limitations were low in the group that used orthosis regularly at significant levels (P < 0.05). A significant relation was detected in logistic regression analysis between age and orthosis use (P < 0.05).

CONCLUSION

Regular orthosis use is at quite low levels in patients with CP. The decision for prescribing orthosis should be made with a rehabilitation team, with the patient included before orthosis is prescribed. Problems related to orthosis use should be addressed at regular intervals after prescribing orthosis.

An effect of spinal and ankle-foot orthoses on gait of spastic diplegic child: A case report

BACKGROUND

In children with spastic cerebral palsy (CP), the most common motor dysfunction is pathological gait.

OBJECTIVE

To evaluate the effectiveness of measures for an individual CP case.

METHODS

The case of one spastic diplegia child has been analyzed. Both lower extremities and spine were examined under three gait conditions: 1) barefoot, 2) with ankle-foot orthoses (AFOs) and thoracolumbosacral spinal orthosis (TLSO), and 3) with TLSO only. Spatiotemporal gait and kinematic parameters of the pelvic, hip, knee, ankle joints, and spine were obtained using Vicon Plug-in-Gait model. The difference (Δ) between the measured values and normative ranges was calculated to determine the efficiency of the orthoses.

RESULTS

Significant differences were found in kinematic and spatiotemporal parameters comparing results between conditions and body sides. The effectiveness of the measures was confirmed by the smallest Δ values in the double and single support time with the AFOs/TLSO and in the stride and stance time with TLSO.

CONCLUSIONS

Based on the study results, the best stability of the spine, ankle plantarflexion, and knee hyperextension is achieved with the AFOs/TLSO; therefore, this combination of measures was considered the most effective. However, not only quantitative parameters should be taken into account, but also the child's willingness and comfort.
