Deep Phenotyping Gait Deficits in Orthopedic Manifestations of Pediatric Cancer Patients
Source: ClinicalTrials.gov · Last updated 18 Jun 2026
Brief summary (registry, in English)
The goal of DEEPGAIT study is to determine how serious walking problems are for pediatric cancer patients who have had orthopedic surgery, how they change over time, and what can be done to help. Healthy participants without cancer will also be included in this study in order to better understand the difference in walking problems between the 2 groups. DEEPGAIT is a long term study that uses advanced tools-including 3D motion capture, muscle sensors, force plates, and wearable devices-to take a detailed look at how these patients move. Their results are compared to healthy children of the same age and sex. PRIMARY OBJECTIVES * Characterize gait deficits in pediatric cancer patients 1 year following orthopedic surgery for lower limb bone sarcoma, soft tissue sarcoma, or steroid-induced avascular necrosis. * Identify personal, disease, treatment and environment risk factors for gait deficits in pediatric cancer patients 1 year following orthopedic surgery for lower limb bone sarcoma, soft tissue sarcoma, or steroid-induced avascular necrosis. SECONDARY OBJECTIVES * Build a library of broadly representative normative reference values to generate age- and sex-matched z-scores to quantify frequency, severity and progression of gait deficits among pediatric cancer patients in relation to healthy controls. * Characterize the changes of gait parameters in pediatric cancer patients with or without gait deficits 1 year after orthopedic surgery for lower limb bone sarcoma, soft tissue sarcoma, or steroid-induced avascular necrosis, up to 5 years after surgery. * Identify personal, disease, treatment and environment risk factors for trajectories of gait deficits in pediatric cancer patients with or without gait deficits 1 year after orthopedic surgery for lower limb bone sarcoma, soft tissue sarcoma, or steroid-induced avascular necrosis, up to 5 years after surgery.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Individuals diagnosed with radiation-induced avascular necrosis.
- Controls:
Other illness
- Individuals with pre-existing genetic/congenital disorders affecting gait will be excluded e.g., cerebral palsy.
- Individuals who self-report health conditions affecting gait and mobility.
- Individuals who have the following conditions: diabetes mellitus due to impaired circulation, sensation and strength, malignant cancers, demyelinating inflammatory and degenerative neurological conditions, pregnancy, obesity (BMI \>40 kg/m2), severe cardiac or pulmonary disease affecting performance of daily activities, history of major surgery affecting gait and mobility, infections or inflammatory arthropathies, severe mobility impairment necessitating dependence on mobility aids for all ambulation.
Age
- Individuals who are unable to follow age-appropriate instructions during the gait assessment.
- Individuals who are unable to follow age-appropriate instructions during the gait assessment.
Other
- Cases:
- Inability or unwillingness of research participant or legal guardian/representative to give written informed consent.
- Individual or legal guardian/representative is unable or unwilling to give written informed consent.
Who the study is looking for
- Cases:
- Participant requiring orthopedic surgery due to a diagnosis of lower limb bone sarcoma, soft tissue sarcoma, or steroid-induced avascular necrosis (Appendix III) and will receive further additional treatment and/or follow-up care at St. Jude.
- Participant is between the ages of ≥5 and ≤20 years old at the time of enrollment.
- Controls:
- Participant is between the ages of ≥5 and ≤20 years old at the time of enrollment.
- Participant (or their parent/legal guardian) considers themself healthy for their age.
- Participant (or their parent/legal guardian) reports being able to participate in normal daily activities of life with respect to their age.
Age in the registry: 5 years to 20 years · Sex: All · Accepts healthy volunteers
