Determining the Relationship Between the Impairment of Selective Voluntary Motor Control and Gait Deviations in Children With Cerebral Palsy Using Simple Video-Based Analyses
(Elsevier Ireland Ltd., 2021) Sardogan, Cansu; Muammer, Rasmi; AKALAN, NAZİF EKİN; Sert, Rukiye; Bilgili, Fuat
Background: The impairment of selective voluntary motor control (SVMC) in children with cerebral palsy (CP) has been shown to correlate with their gait characteristics using complex 3D gait analysis systems (3DGA); however, this relationship has not been investigated using simple video-based observational gait analysis (VBOGA). The aim of this study was to determine the relationship between VBOGA and SVMC of the lower extremities in children with CP. Methods: Forty-two CP children 10.9 +/- 5.7 years old with Gross Motor Function Classification System (GMFCS) levels I-III participated in the study. Their gait characteristics were assessed using the Edinburgh Visual Gait Score (EVGS), and selective voluntary motor control was tested using the Selective Control Assessment of the Lower Extremity (SCALE). Spearman's rho correlation test with Cohen's classification were used in the statistical analyses. Results: The GMFCS levels (r = 0.604, p < 0.001), foot clearance (r = -0.584. p < 0.001), and maximum ankle dorsiflexion (r = -0.567, p < 0.001) during the swing phase had strong correlations with total SCALE scores. There was also a moderate correlation between total SCALE scores and total EVGS (r = -0.494, p < 0.001), knee extension in the terminal swing phase (r = -0.353, p < 0.001), peak sagittal trunk position (r = -0.316, p < 0.005), and maximum lateral shift (r = -0.37, p < 0.001). Conclusion: Impaired lower extremity SVMC was noticeably related to the foot and ankle movements in the swing phase and initial stance during walking as well as the total EVGS scores and sagittal and frontal trunk movements. The SCALE correlations with VBOGA were similar those observed in the complex 3DGA in the literature; therefore, we suggest that SVMC impairment of gait could be evaluated using simple VBOGA. These findings may help to tailor physical therapy programs for CP children to increase their motor control and walking quality.

Does One Leg Standing Duration Have Relation With GMFM Scores and Stability in Stance Phase for Hemiplegic Children ?
(2018-09) N. Ekin Akalan; Halenur, Evrendilek; Karaca, Gülşah; Bilgili, Fuat; Ertürk, Gamze; 268636; 176320; 268497; 268498; 237820
This paper reports the results of a study to validate a measure of gross motor function in detecting change in the motor function of disabled children. Physiotherapists used this instrument to assess 111 patients with cerebral palsy, 25 with head injury and 34 non-disabled preschool children on two occasions, the second after an interval of four to six months. Parents and therapists independently rated the children's function within two weeks of each assessment, and a sample of paired assessments was videotaped for 'blind' evaluation by therapists. Correlations between scores for change on this measure and the judgments of change by parents, therapists and 'blind' evaluators supported the hypothesis that the instrument would be responsive to both negative and positive changes.

(2019-10-18) EVRENDILEK, HALENUR; Karaca, Gülşah; Ertürk, Gamze; Bilgili, Fuat; AKALAN, NAZİF EKİN; ÖNERGE, KÜBRA
AMAÇ Çalışmanın amacı; femoral anteversiyon artışı (FAA) olan çocuklarda hipermobilite, kas kuvveti ve 3 boyutlu yürüme analizi parametreleri arasındaki ilişkiyi araştırmaktır. YÖNTEM FAA olan 7 çocuk (14 bacak, ort.yaş:9.14 ± 0.3, trokanter prominens açı testi(TPAT):28 ± 6.2°) çalışmaya dahil edildi. Çocukların femoral anteversiyon açıları, eklem mobiliteleri ve maksimal izometrik kas kuvvetleri sırasıyla TPAT, Beighton testi ve el dinamometresiyle (Lafayette Instruments,USA) değerlendirildi. Tüm katılımcılara normal hızlarında yürürken 3 boyutlu yürüme analizleri yapılarak pelvis, kalça ve diz kinematik parametreleri incelendi. Parametreler arasındaki ilişkiler, verilerin normal dağılımlarına göre Pearson ve Spearman korelasyon testleri kullanılarak değerlendirildi. Verilerin istatistiksel olarak anlamlılık düzeyi (p<0.05) olarak kabul edildi ve sonuçlar Cohen sınıflamasına göre yorumlandı. BULGULAR Beighton testi skoru ile kalça ekstansör(r: -.70) ve diz ekstansör(r: -.91) kas kuvvetleri, minimum diz fleksiyon açısı(r: -.83) arasında yüksek korelasyon bulundu. TPAT değerleri ise kalça abduktör kas kuvveti(r: -.77) ve ortalama kalça rotasyon açısıyla yüksek korelasyon gösterdi(r: .60). TARTIŞMA Literatürde, FAA olan çocukların yürüme sırasında ortalama kalça iç rotasyon, pelvik oblikite ve duruş fazında diz ekstansiyon parametrelerinin arttığı gösterilmiştir. Bu çalışma, zayıf kalça ekstansör ve abduktür, diz fleksör ve ekstansör kaslarındaki zayıflığın kinematik değişimlerle ilişkili olabildiğini göstermiştir. Ayrıca, literatürle uyumlu olarak ortalama kalça internal rotasyon parametresiyle kalça abdüktör kas kuvvetinin TPAT açısıyla anlamlı olarak ilişkili olduğu bulumuştur. FAA olan çocuklarda sıkça görülebilen hipermobilitenin, kalça ve diz ekstansör kas zayıflığı ile duruş fazında hiperekstansiyon artışında rolü olabilir. Sonuç olarak, kalça abdüktör ve ekstansör, diz fleksör ve ekstansör kas kuvvetlerinin arttırılması, FAA olan hipermobil çocuklarda alt ekstremite fonksiyonun iyileştirilmesi için önemlidir.

Intraoperative Testing of Passive and Active State Mechanics of Spastic Semitendinosus in Conditions Involving Intermuscular Mechanical Interactions and Gait Relevant Joint Positions
(Elsevier, 2020) Kaya, Cemre S.; Bilgili, Fuat; AKALAN, NAZİF EKİN; Yücesoy, Can A.
In cerebral palsy (CP) patients suffering pathological knee joint motion, spastic muscle's passive state forces have not been quantified intraoperatively. Besides, assessment of spastic muscle's active state forces in conditions involving intermuscular mechanical interactions and gait relevant joint positions is lacking. Therefore, the source of flexor forces limiting joint motion remains unclear. The aim was to test the following hypotheses: (i) in both passive and active states, spastic semitendinosus (ST) per se shows its highest forces within gait relevant knee angle (KA) range and (ii) due to intermuscular mechanical interactions, the active state forces elevate. Isometric forces (seven children with CP, GMFCS-II) were measured during surgery over a range of KA from flexion to full extension, at hip angle (HA) = 45 degrees and 20 degrees, in four conditions: (I) passive state, (II) individual stimulation of the ST, simultaneous stimulation of the ST (III) with its synergists, and (IV) also with an antagonist. Gait analyses: intraoperative data for KA = 17-61 degrees (HA = 45 degrees) and KA = 0-33 degrees (HA = 20 degrees) represent the loading response and terminal swing, and mid/terminal stance phases of gait, respectively. Intraoperative tests: Passive forces maximally approximated half of peak force in condition II (HA = 45 degrees). Added muscle activations did increase muscle forces significantly (HA = 45 degrees: on average by 42.0% and 72.5%; HA = 20 degrees: maximally by 131.8% and 123.7%, respectively in conditions III and IV, p < 0.01). In conclusion, intermuscular mechanical interactions yield elevated active state forces, which are well above passive state forces. This indicates that intermuscular mechanical interactions may be a source of high flexor forces in CP. (C) 2020 Elsevier Ltd. All rights reserved.

The Relationship of One Leg Standing Duration to GMFM Scores and to Stance Phase of Walking in Children with Hemiplegic Cerebral Palsy
(Taylor & Francis, 2021) UZUNOĞLU, GAMZE ERTÜRK; AKALAN, NAZİF EKİN; EVRENDİLEK, HALENUR; YILMAZ, GÜLŞAH KARACA; Bilgili, Fuat
Background: Lack of stability during stance negatively impacts gait and motor function for children with unilateral cerebral palsy. Improving stability and balance are the focus for gait rehabilitation). The One-Leg-Standing-Test may give valuable information about motor function and stability of stance for patients with unilateral cerebral palsy. Objective: This study aimed to investigate the relationship between the One-Leg-Standing-Test and the gross-motor-function-measurement and single-limb support time. Methods: The study included 18 patients with unilateral cerebral palsy (age 11.08 [SD 2.84] years old). The One-Leg-Standing-Test and pedobarographic evaluation were performed. Sections D and E of the gross-motor-function-measurement were assessed, and in pedobarographic evaluation, the single-limb support time (the total duration of mid-stance and terminal-stance during walking) was calculated to describe stability during stance. Results: For patients, the One-Leg-Standing-Test scores and single-limb support time values were lower on the affected side than on the unaffected side. The One-Leg-Standing-Test was correlated with single-limb support time (p = .02, r = 0.60) and section E (p < .01, r = 0.59) values. The One-Leg-Standing-Test was also correlated to total stance phase and section D. Conclusion: The One-Leg-Standing-Test gives valuable information about gross-motor-function but cannot be substituted for motor function tests. The single-limb support time value may be used to describe stability in stance during walking.

Residual Gait Deviations in Children Treated by Medial Open Reduction for Developmental Dysplasia of the Hip at Long-Term Follow-up: A Comparison With Healthy Controls
(Springer, 2024) Demirel, Mehmet; EVRENDİLEK, HALENUR; AKALAN, NAZİF EKİN; Bilgili, Fuat; Meric, Emre; Kuchimov, Shavkat; ÖNERGE, KÜBRA
Purpose This study aimed to analyze and compare gait patterns and deviations at long-term follow-up in children who received medial open reduction (MOR) before 18 months for unilateral or bilateral hip developmental dysplasia (DDH). Methods A retrospective chart review was conducted on children who underwent MOR. The study population was divided into two groups: the unilateral group, including unilateral (five children with unilateral) and bilateral (five children with bilateral DDH). Ten healthy children were recruited for the control group. Spatiotemporal, kinematic, stiff-knee gait (SKG), and kinetic gait characteristics were analyzed. Results Stance time was significantly shorter in both the unilateral (median [IQR]; 590 ms, [560.0-612.5] and bilateral (575 ms, [550-637.5]) groups than in the control group (650, [602.5-677.5]) (p < 0.001), whereas swing time did not differ substantially (p = 0.065) There was no considerable difference in the mean knee flexion at swing between the unilateral (31.6 degrees, [30-36]) and control (30.11 degrees, [27.8-33.6] groups (p > 0.05), but the bilateral group (28.5 degrees, [24.9-32.1]) showed the lower values than the other groups (p < 0.001 for bilateral vs unilateral group; p = 0.008 bilateral vs unilateral group). All the SKG parameters significantly differed among the groups in multi-group comparisons (p < 0.001 for each parameter). Three children had borderline SKG, and two had not-stiff limbs in the unilateral group. In the bilateral group, four children had stiff limbs, and one had borderline SKG. Most kinetic gait parameters were not statistically different between groups (p > 0.05). Conclusion This study has revealed notable deviations in gait patterns of children with DDH treated by MOR at long-term follow-up compared to healthy children's gait. MOR could negatively affect pelvic motion during gait due to impaired functions of the iliopsoas and adductor muscles, and SKG can be encountered secondary to iliopsoas weakness.
