AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with spastic paresis after a stroke or an incomplete spinal cord injury, and for healthy adults, to study the Achilles tendon while walking.

Age
18 years or older
Sex
Men and women
Disease stage
Stroke more than 7 days ago, or incomplete spinal cord injury graded ASIA AIS C or D. Voluntary muscle strength rated 2 to 4 on the MRC scale. Walking ability rated 3 to 8 on the New Functional Ambulation Classification (stroke) or 13-20 on the WISCI-II scale (spinal cord injury).
Earlier treatment
Patients cannot have had calf surgery, surgery to reduce calf spasticity, or an injection such as botulinum toxin in the calf muscles in the last 6 months.

Main reasons for not taking part

  • Under 18 years old
  • Calf surgery or botulinum toxin injection in the calf in the last 6 months (patients)
  • Progressive condition that makes exertion unsafe, such as syrinx or unstable heart and circulation
  • Nerve or other disease of the lower limb in question (patients)
  • Healthy volunteers: calf surgery, any neurological condition, or lower limb muscle injury, fracture or sprain in the last 3 months

Characterization of Mechanical Properties of Achilles Tendon During Gait in Spastic Paresis Syndrome

The purpose of this study is to evaluate the mechanical properties of the Achilles tendon (stiffness, length, volume) and the force production capacities of the gastrocnemius medialis muscle in patients with spastic paresis (post-stroke or incomplete spinal cord injury) compared to healthy subjects, during gait.

Inclusion: Study population:; Cognitive abilities compatible with the experiment: no language or judgement disorders preventing understanding of the research or expression of consent. An aphasia severity score greater than or equal to 3 on the Boston Diagnostic Aphasia Examination (BDAE) scale will be required for inclusion; Post-stroke population:; Adult male or female; Patient who has had a stroke > 7 days ago; Patient hospitalised (in conventional hospitalisation or day hospital) in the neurological physical and medical rehabilitation department of Nantes University Hospital; Patients with voluntary motor function rated between 2 and 4 on the MRC (Medical Research Council) scale at the GM level; Patients classified as 3 to 8 on the New Functional Ambulation Classification; Indication to perform a quantified gait analysis as part of clinical management; Post-spinal cord injury population:; Adult men or women; Patients with incomplete spinal cord injury graded ASIA AIS C or D from C2 to L5; Patients hospitalised (in conventional hospitalisation or day hospital) in the neurological physical and occupational therapy department of Nantes University Hospital; Patients with voluntary motor function rated between 2 and 4 on the MRC (Medical Research Council) scale at GM level; Patients rated 13-20 on the WISCI-II scale; Indication for a quantified gait analysis as part of clinical care; Healthy population:; Adult men or women with no nervous system disorders.

Exclusion: Post-stroke and post-spinal cord injury population:; History of calf surgery, surgery to reduce triceps surae spasticity, or intramuscular injection (e.g. botulinum toxin) in the plantar flexors < 6 months; Patients with a progressive condition that contraindicates exertion (syrinx, cardiovascular instability); History of calf surgery; History of muscle injury, fracture or sprain of the lower limb < 3 months; History of neurological condition; Minors; Peripheral pathology of the lower limb in question; Healthy population:.
