About this study

Official title: The Evaluation of Medial Longitudinal Arch Morphology in Children With Spastic Diplegic Cerebral Palsy by Arch Height Index Measurement Method: A Pilot Study

Foot deformities are one of the most common orthopedic problems in patients with cerebral palsy(CP). Various methods have been proposed to evaluate foot morphology. Arch height index (AHI) measurement is a simple and quantitative method that can be applied in outpatient settings to evaluate the morphology of the medial longitudinal arch(MLA) of the foot. In this study, we aim to investigate the feasibility of AHI measurement in children with CP and, to identify other clinical findings that may be related to foot arch height determined by the AHI method.

Read the detailed description

Cerebral palsy (CP) is a posture, movement, and motor dysfunction that occurs as a result of non-progressive damage of the developing brain during the intrauterine period or early childhood. Foot deformities, including pes planus and pes cavus, are common in children with CP and deteriorate posture and mobility due to its progressive nature and accompanying pain. Spasticity, muscle imbalances, soft tissue changes, and subsequent skeletal disorders are blamed for foot deformities in patients with CP.

Some methods such as foot posture index, navicular drop test, footprint methods, and radiological imaging have been described to identify and evaluate the MLA and foot/ankle posture. Arch height index (AHI) measurement is a novel method that evaluates especially medial longitudinal arch(MLA) morphology, with proven validity and reliability. It is essentially based on the measurement of the dorsum height and the length of the foot by using various caliper systems during varying degrees of load-bearing like sitting or standing. AHI measurement has some advantages over other methods. Measuring AHI during varying degrees of load-bearing such as sitting or standing allows us to quantitatively assess the mobility of the MLA. AHI measurement should be preferred in patients with foot sole skin disorders where footprint measurement methods are inefficient. Its results are not affected by some factors such as x-ray tube angle differences in foot radiography. It does not pose a risk of radiation exposure and is easy to apply. However, there is no data on the effectiveness of the AHI method in determining the MLA morphology in children with CP.

The first hypothesis of this study is that AHI measurement results in patients with CP correlate with data obtained from standard foot radiographs. The second aim of the study is to investigate the relationship between MLA morphology and other findings such as joint range of motion and spasticity of lower extremity muscles in patients with CP.

Patients with spastic diplegic cerebral palsy who were admitted to the Physical Medicine and Rehabilitation Department of our hospital will be evaluated in terms of eligibility criteria for the study. Eligible patients will be informed about the trial, and informed consent will be obtained from those who agree to participate. It was planned to recruit 24 subjects with a correlation coefficient of 0.8, a power of 0.90, and a margin of error of 0.05 to determine the correlation between AHI and quantitative foot radiography data.

Demographic data, body mass indexes, physical examination findings including gait patterns, ankle and foot range of motion and tone of the certain lower extremity muscles of participants will be recorded. MLA morphology will be evaluated by foot radiographs and AHI measurements. The AHI measurement will be made both in the bipedal standing and in the sitting position with both feet calmly on the ground. AHI will be calculated by proportioning the height of the dorsum measured from the middle 1/2 of the total length of the foot to truncated foot length.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Arch Height Index while bipedeal standing

    The ratio of the height of the dorsum measured from the middle 1/2 of the total length of the foot to truncated foot length while bipedal standing

    Measured: Initial evaluation of the participant

  2. Arch Height Index while sitting

    he ratio of the height of the dorsum measured from the middle 1/2 of the total length of the foot to truncated foot length while sitting with feet calmly on the ground

    Measured: Initial evaluation of the participant

  3. Navicular Index

    The ratio of the height of the navicular bone from the ground to the height of the medial longitudinal arch of the foot on lateral foot radiograph.

    Measured: Initial evaluation of the participant

  4. Calcaneal Inclination Angle

    Angle formed by a line tangent to the inferior cortex of the calcaneus and an horizontal reference line of the plantar plane on lateral foot radiograph.

    Measured: Initial evaluation of the participant

  5. Lateral Talo-first metatarsal Angle

    Angle formed by the longitudinal axis of the first metatarsal shaft and the longitudinal axis of the talus on lateral foot radiograph.

    Measured: Initial evaluation of the participant

Secondary outcomes (3)
  1. Popliteal angle

    Popliteal angle was defined as the acute angle between tibia and femur when the knee joint was passively extended with the hip flexed 90 degrees.

    Measured: Initial evaluation of the participant

  2. Ankle range of motion

    The degree of flexion, extension, inversion, and eversion of the ankle joint that measured regarding the neutral zero methods.

    Measured: Initial evaluation of the participant

  3. The degree of spasticity of the certain muscles of the lower extremities

    The tonus of hip flexor, hip adductor, knee extensor, knee flexor, ankle plantar flexor, and ankle invertor muscles will be evaluated by the Modified Ashworth Scale. Achilles' tendon tightness will be evaluated by the Silfverskiöld Test.

    Measured: Initial evaluation of the participant
