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.

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).

Does clinically measured ankle plantar flexor muscle strength or weakness correlate with walking performance in healthy individuals?

Objective: Muscle strength is usually measured using isometric hand-held dynamometers (HHDs) in the clinic. However, during functional activities, the muscle acts more dynamically. The aim of this study was to investigate the relation between clinically measured plantar flexor (PF) muscle strength (PFMS) and laboratory measurements of peak ankle plantar flexion power generation (APFPG), peak ankle moment (PAM), peak plantar flexion velocity (PFV) and mean gait velocity in healthy participants.

Weakening iliopsoas muscle in healthy adults may induce stiff knee pattern.

Objective: The goal of the present study was to investigate the relationship between iliopsoas muscle group weakness and related hip joint velocity reduction and stiff-knee gait (SKG) during walking in healthy individuals.

Methods: A load of 5% of each individual's body weight was placed on non-dominant thigh of 15 neurologically intact, able-bodied participants (average age: 22.4 ± 0.

Plantar flexor muscle weakness may cause stiff-knee gait.

Aim: The iterative simulation studies proclaim that plantar flexor (PF) muscle weakness is one of the contributors of stiff knee gait (SKG), although, whether isolated PF weakness generates SKG has not been validated in able-bodied people or individuals with neuromuscular disorders. The aim of the study was to investigate the effects of isolated PF muscle weakness on knee flexion velocity and SKG in healthy individuals.

Method: Twenty able-bodied young adults (23±3 years) participated in this study.

Femoral derotation osteotomy with multi-level soft tissue procedures in children with cerebral palsy: Does it improve gait quality?

Purpose: Poor motor control and delayed thumb function and a delay in walking are the main factors which retard the natural decrease of the femoral anteversion (FA) with age. In addition, cerebral palsy (CP) patients usually have muscular imbalance around the hip as well as muscle contractures, both of which are main factors accounting for the increased FA which is commonly present in CP patients. The purpose of this retrospective study was to analyze the mid-term results of femoral derotational osteotomy (FDO) on the clinical findings, temporospatial and kinematic parameters of gait in children with CP.

Contributors of stiff knee gait pattern for able bodies: Hip and knee velocity reduction and tiptoe gait.

Unlabelled: Stiff-knee gait (SKG) is commonly encountered in clinic; many other gait abnormalities are seen together with this pathology. Simulation studies revealed that diminished knee flexion (KF) velocity and increased knee extension moments are strongly related with SKG. This study aimed to determine whether tiptoe walking and hip-knee flexion velocity reduction causes SKG pattern in healthy participants.

Discrimination of abnormal gait parameters due to increased femoral anteversion from other effects in cerebral palsy.

The effects of increased femoral anteversion (IFA) on gait pattern have a complex relationship with other orthopaedic and neurological abnormalities of cerebral palsy (CP). The aim of this study was to differentiate the effects of IFA from other factors in CP. The four groups in this study included: 15 typically developing children (Group: TDC) (age: 9.

Effects of unilateral backpack carriage on biomechanics of gait in adolescents: a kinematic analysis.

Objective: The aim of this study was to analyze the biomechanical alterations during unilateral backpack carriage in adolescents and to compare the kinematic parameters of the loaded and unloaded sides.

Methods: Twenty adolescents (mean age: 13 ± 1.2 years) were assessed during walking with no backpack and with a backpack on one shoulder.
