Hereditary spastic paraplegia

This trial tests a single injection of MELPIDA, a gene therapy that delivers a working copy of the AP4M1 gene directly into the spinal fluid of children with SPG50. SPG50 is a rare genetic condition that causes muscle stiffness, intellectual disability, and developmental delays. …

This phase 3 trial tests a one-time gene therapy called MELPIDA for children with SPG50, a rare genetic disease that causes progressive paralysis and developmental delays. The study will give the treatment via a spinal injection to 24 children aged 4 months to 6 years and compare…

This study tests a noninvasive spinal cord stimulation (tSCS) to improve walking and reduce muscle stiffness in 15 adults with hereditary spastic paraplegia (HSP), a rare nerve condition. Participants receive stimulation through skin electrodes on the lower back twice a week for …

This study tests whether whole-body electrical muscle stimulation (WB-EMS) can help adults with neuromuscular diseases like ALS, SMA, and muscular dystrophy exercise safely. Because these conditions weaken the nerves that control muscles, traditional exercise is often too hard. W…

This study tests a 12-week supervised rehabilitation program for people with two rare genetic conditions that cause walking and balance problems (spastic ataxias). The program includes twice-weekly therapy sessions and once-weekly pool exercises. Researchers want to see if it red…

This study aims to learn more about rare disorders that affect how the body processes chemicals called pyrimidines and purines. These disorders can cause problems in the brain, blood, kidneys, and immune system, ranging from mild to life-threatening. Researchers will compare test…

This study looks at how muscles grow and change in children with cerebral palsy (CP) by examining tiny samples from leg muscles. Researchers will compare these microscopic findings with muscle images and movement tests. The goal is to better understand why muscles in CP develop d…

This study is creating a detailed registry of 500 people with hereditary spastic paraplegia (HSP), a rare disorder that causes progressive leg stiffness and weakness. Researchers will collect medical history, genetic data, and patient feedback over time to better understand how t…

This study aims to uncover the genetic causes of hereditary spastic paraplegia (HSP), a group of rare neurological diseases that cause progressive muscle stiffness and weakness. Researchers at Boston Children's Hospital will analyze DNA from 200 people with HSP to find genetic va…

This study is collecting health data and blood samples from 100 people with specific types of hereditary spastic paraplegia (SPG4 and SPG5A). The goal is to create a shared database and biobank to better understand how the disease progresses. This information will help prepare fo…

This study collects health information and biological samples from up to 700 people under 30 with early-onset hereditary spastic paraplegia (HSP). Researchers aim to better understand how the disease progresses over time and create a registry for future studies. Participants prov…

This study examines the role of the plantaris, a small calf muscle, in children having surgery for tight ankles (equinus). Researchers will randomly change the order of tendon cuts during surgery to measure how much each contributes to ankle movement. The goal is to understand if…
