Gait in 5-year-old children with idiopathic clubfoot: A cohort study of 59 children, focusing on foot involvement and the contralateral foot

Comparison of kinematics and pedobarography findings between the unaffected foot of patients with unilateral clubfoot and controls

PURPOSE

Idiopathic clubfoot (ICF) involves structural abnormalities in the lower extremities. Approximately half of patients have unilateral ICF, which could be due to differences in limb formation. The contralateral unaffected foot may have subclinical ICF. The objectives were to compare ankle and foot kinematics and pedobarography findings between the unaffected foot of patients with unilateral ICF and controls.

METHODS

Eleven children with unilateral ICF (11 unaffected feet, 11.7 ± 3.8 years) and 15 age-matched controls (30 control feet, 11.1 ± 3.0 years) were enroled. Five complete gait trials were performed. Data were collected using ten cameras and a two m long Footscan system and compared between groups using the Wilcoxon rank sum test.

RESULTS

All children with ICF underwent the selective soft tissue release procedure. The unaffected feet showed limited ranges in inversion-eversion and dorsiflexion-plantar flexion on kinematic analysis. There was a delay in landing time in all regions of the foot during heel rise and propulsion. The peak time was achieved significantly later in the unaffected feet compared to the controls. Although plantar pressure parameters were comparable, unaffected feet showed a larger contact area in the midfoot region.

CONCLUSIONS

Gait data on the unaffected foot in unilateral ICF patients do not correspond to those of controls despite an indistinguishable clinical appearance. This could be due to the effect of treatment, the process of foot development, or a combination. The relationship between genetics and gait deviation in patients with unilateral ICF needs further evaluation. The unaffected foot should receive similar attention during follow-up.

Three-dimensional gait analysis of orthopaedic common foot and ankle joint diseases

Walking is an indispensable mode of transportation for human survival. Gait is a characteristic of walking. In the clinic, patients with different diseases exhibit different gait characteristics. Gait analysis describes the specific situation of human gait abnormalities by observing and studying the kinematics and dynamics of limbs and joints during human walking and depicting the corresponding geometric curves and values. In foot and ankle diseases, gait analysis can evaluate the degree and nature of gait abnormalities in patients and provide an important basis for the diagnosis of patients' diseases, the correction of abnormal gait and related treatment methods. This article reviews the relevant literature, expounds on the clinical consensus on gait, and summarizes the gait characteristics of patients with common ankle and foot diseases. Starting from the gait characteristics of individuals with different diseases, we hope to provide support and reference for the diagnosis, treatment and rehabilitation of clinically related diseases.

Kinematic Gait Impairments in Children with Clubfeet Treated by the Ponseti Method: A Systematic Review and Meta-Analysis

BACKGROUND

Being aware of possible gait impairments in Ponseti-treated clubfoot children might be useful for optimizing initial and additional treatment. Therefore, this systematic review and meta-analysis aimed to identify kinematic gait abnormalities in children with clubfoot treated with the Ponseti method (with and without relapse).

METHODS

A systematic search was conducted. Studies comparing kinematic gait parameters of Ponseti-treated clubfoot children to healthy controls were included. Meta-analyses and qualitative analyses were conducted on the extracted data.

RESULTS

Twenty studies were identified. Twelve of the 153 reported kinematic outcome measures could be included in the meta-analysis. Plantarflexion at push-off, maximum ankle dorsiflexion during the swing, maximal plantarflexion, and ankle range of motion was significantly lower in Ponseti-treated clubfoot children. Ponseti-treated clubfoot children showed more internal foot progression. Qualitative analysis revealed 51 parameters in which pre-treatment relapse clubfeet deviated from healthy controls.

CONCLUSIONS

Ponseti-treated clubfoot children showed several kinematic gait differences from healthy controls. In future studies, homogeneity in measured variables and study population and implementation of multi-segmental foot models will aid in comparing studies and understanding clubfoot complexity and treatment outcomes. The question remains as to what functional problems gait impairments lead to and whether additional treatment could address these problems.

Forefoot adduction and forefoot supination as kinematic indicators of relapse clubfoot

BACKGROUND

Understanding the kinematic characteristics of relapse clubfoot compared to successfully treated clubfoot could aid early identification of a relapse and improve treatment planning. The usage of a multi segment foot model is essential in order to grasp the full complexity of the multi-planar and multi-joint deformity of the clubfoot.

RESEARCH QUESTION

The purpose of this study was to identify differences in foot kinematics, using a multi-segment foot model, during gait between patients with Ponseti treated clubfoot with and without a relapse and age-matched healthy controls.

METHODS

A cross-sectional study was carried out including 11 patients with relapse clubfoot, 11 patients with clubfoot and 15 controls. Gait analysis was performed using an extended Helen Hayes model combined with the Oxford Foot Model. Statistical analysis included statistical parametric mapping and discrete analysis of kinematic gait parameters of the pelvis, hip, knee, ankle, hindfoot and forefoot in the sagittal, frontal and transversal plane.

RESULTS

The relapse group showed significantly increased forefoot adduction in relation with the hindfoot and the tibia. Furthermore, this group showed increased forefoot supination in relation with the tibia during stance, whereas during swing increased forefoot supination in relation with the hindfoot was found in patients with relapse clubfoot compared with non-relapse clubfoot.

SIGNIFICANCE

Forefoot adduction and forefoot supination could be kinematic indicators of relapse clubfoot, which might be useful in early identification of a relapse clubfoot. Subsequently, this could aid the optimization of clinical decision making and treatment planning for children with clubfoot.

Talipes Equinovarus Treatment in Infants Treated by the Ponseti Method Compared With Posterior-Only Release: A Mid-Childhood Comparison of Results

The aim of this study is to evaluate children in middle childhood with clubfoot treated with Ponseti method vs posterior-only release and to compare their results to a control group with 4 modules (physical examination, gait study, radiographic measurements, and questionnaires). From 01/01/2004 until 01/01/2009, 31 children (45 feet) were treated with the posterior-only release protocol and 22 patients (34 feet) were treated with the Ponseti method. In 2016, patients were evaluated and compared with 25 children without neuromuscular disorders. Parents completed 3 outcome questionnaires. Radiographs evaluated residual deformity and osteoarthritis. A physical examination and a 3-dimensional gait analysis were performed to evaluate range of motion, kinematic, and kinetic data. Recurrence rate was similar between treatment groups; however, type of surgery to treat residual deformity was more aggressive in the posterior-only release (91% required major surgery), p = .024. Radiographic examination showed similar residual deformity with greater hindfoot varus in posterior-only release (68%), p = .02. Reduced cadence, increased stance dorsiflexion, calcaneus gait and forced eversion prior to swing were the main characteristics of gait in posterior-only release. Four (11%) feet treated with posterior-only release vs 11 (33%) feet treated with Ponseti method had a normal gait, p = .016. Our study showed that biomechanical function and long-term outcomes of children in middle childhood treated with the Ponseti method more closely compare with healthy individuals than those treated using posterior-only surgical technique.

A comparative study of pedobarography and ankle kinematics between children with idiopathic clubfoot after a soft tissue release procedure and controls

PURPOSE

Surgery for idiopathic clubfoot, though limited in indications, should be performed by a selective soft tissue release. Aims of the study were to evaluate the pedobarography and ankle kinematics of the clubfoot post-surgery and compare with controls.

METHODS

Twenty-two patients (33 clubfeet) and 22 normal children (44 feet) were enrolled into the cross-sectional study. Demographic data were recorded. Plantar force measurements and ankle kinematic data were obtained and compared between clubfoot patients and controls by pedobarography and 3-dimensional gait analysis.

RESULTS

Clubfoot patients were operated at an average age of 12.8 ± 8.1 months. The average follow-up was 9.9 ± 3.9 years. Demographic data were comparable between the two groups. The plantar force in clubfoot patients was significantly lower than controls (108.2 ± 86.7 vs. 150.9 ± 73.9 N, p = 0.03). Clubfoot patients demonstrated a longer contact time, larger contact area, lower peak pressure, and force relative to body weight in toe, midfoot, and heel areas. The impulse was comparable between the two groups but the contact area, force, and force time integral concentrated at the midfoot region of the clubfoot. The ankle kinematics in clubfoot patients demonstrated a dorsiflexed position through late toe off. Range of dorsiflexion in the clubfoot was significantly higher than in controls. Foot adduction during stance, limited inversion-eversion, and limited plantar flexion during loading response and toe off were observed.

CONCLUSION

The results underscore the importance of limited soft tissue release during clubfoot surgery. Although the procedure could preserve range of motion at the ankle joint, muscle weakness and flatfoot deformity are prevalent.

Gross Motor Skills in Children With Idiopathic Clubfoot and the Association Between Gross Motor Skills, Foot Involvement, Gait, and Foot Motion

BACKGROUND

Little is known regarding gross motor skills (GMS) in children with idiopathic clubfoot (IC). This study describes GMS, specifically foot involvement and asymmetries, and analyses the association between GMS, gait, and foot status in children with IC.

METHODS

Gross motor tasks and gait were analyzed in children with IC and typically developed (TD) children. GMS were assessed using videotapes and the Clubfoot Assessment Protocol (CAP). The Gait Deviation Index (GDI) and GDI-Kinetic were calculated from gait analyses. Children were divided into bilateral, unilateral clubfoot, or TD groups. To analyze asymmetries, feet within each group were further classified into superior or inferior foot, depending on their CAP scores. Correlations identified associations between CAP and GDI, GDI-Kinetic, passive foot motion, and Dimeglio Classification Scores at birth in the clubfeet.

RESULTS

In total, 75 children (mean age, 5 years) were enrolled (bilateral n=22, unilateral clubfoot n=25, TD=28). Children with clubfeet demonstrated significantly lower GMS, gait, and foot motion compared with TD children. One leg standing and hopping deviated in 84% and 91%, respectively, in at least one foot in children with clubfoot. Gross motor asymmetries were evident in both children with bilateral and unilateral involvement. In children with unilateral clubfoot, contralateral feet showed few deviations in GMS compared with TD; however, differences existed in gait and foot motion. The association between GMS and gait, foot motion, and initial foot status varied between poor and moderate.

CONCLUSIONS

Gross motor deficits and asymmetries are present in children with both bilateral and unilateral IC. Development of GMS of the contralateral foot mirrors that of TD children, but modifies to the clubfoot in gait and foot motion. The weak association with gait, foot motion, and initial clubfoot severity indicates that gross motor measurements represent a different outcome entity in clubfoot treatment. We therefore, recommend gross motor task evaluation for children with IC.

Gait kinetics in children with clubfeet treated surgically or with the Ponseti method: A meta-analysis

BACKGROUND

Currently, the Ponseti method is the gold standard for treatment of clubfeet. For long-term functional evaluation of this method, gait analysis can be performed. Previous studies have assessed gait differences between Ponseti treated clubfeet and healthy controls.

RESEARCH QUESTION/PURPOSE

The aims of this systematic review were to compare the gait kinetics of Ponseti treated clubfeet with healthy controls and to compare the gait kinetics between clubfoot patients treated with the Ponseti method or surgically.

METHODS

A systematic search was performed in Embase, Medline Ovid, Web of Science, Scopus, Cochrane, Cinahl ebsco, and Google scholar, for studies reporting on gait kinetics in children with clubfeet treated with the Ponseti method. Studies were excluded if they only used EMG or pedobarography. Data were extracted and a risk of bias was assessed. Meta-analyses and qualitative analyses were performed.

RESULTS

Nine studies were included, of which five were included in the meta-analyses. The meta-analyses showed that ankle plantarflexor moment (95% CI -0.25 to -0.19) and ankle power (95% CI -0.89 to -0.60, were significantly lower in the Ponseti treated clubfeet compared to the healthy controls. No significant difference was found in ankle dorsiflexor and plantarflexor moment, and ankle power between clubfeet treated with surgery compared to the Ponseti method.

SIGNIFICANCE

Differences in gait kinetics are present when comparing Ponseti treated clubfeet with healthy controls. However, there is no significant difference between surgically and Ponseti treated clubfeet. These results give more insight in the possibilities of improving the gait pattern of patients treated for clubfeet.
