Mitochondrial Membrane Protein Neurodegeneration (MPAN)
Study Details
Study Description
Brief Summary
The purpose of this case study was to investigate the effects of therapeutic intervention in 9- and 12-year-old brothers with MPAN. The main hypothesis it aims to answer is:
-A 6-week balance and coordination focused rehabilitation program improves independence and gait parameters in patients with MPAN.

Detailed Description
Neurodegeneration with brain iron accumulation (NBIA) comprises a heterogeneous group of disorders with accumulation of iron in the brain, mostly basal ganglia. Mutations within C19orf12 have recently been identified in patients with NBIA. This C19orf12 gene -located in mitochondria and endoplasmic reticulum- encodes a mitochondrial membrane protein and the abbreviation MPAN. Pathogenic mutations in this gene are postulated to cause dysfunction of lipid homeostasis in mitochondria.
Patients with MPAN typically present with gait disturbance due to lower limb spasticity and dystonia, parkinsonism with subsequent spastic paresis, dysarthria, cerebellar ataxia, behavioral problems, dementia, psychomotor delay, peripheral neuropathy, visual changes like optic atrophy as well as bowel/bladder incontinence; however, MPAN has a greater variability compared with other NBIA cases in terms of age of onset (age three to 30 years) and speed of progression.
This study aims to investigate the effects of therapeutic intervention in male brothers, age 9 and 12, with MPAN. In particular, this study tested the following hypotheses after 6 weeks of rehabilitation by measuring muscle strength, muscle tone, range of motion , balance and coordination: (1) After the training period, muscle strenght, muscle tone and range of motion would be improved, (2) these developments in body function can lead to increase balance and coordination, and (3) due to the these improvements, functional independency may increase.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Balance and Coordination Since it is a case study, there will be only one group in the study. |
Other: Passive Stretching
Sustained passive stretching of hamstring, tendo-achilles, and adductors 10 (30 s, with three repetitions, five times per week)
Other: Mobilization
Grade four mobilizations is a stretching motion performed at the talocrural joint with anterior-posterior gliding. Mobilization was performed once a day, 6 times a day, and 5 times a week, only on both deformed feet of the older sibling
Other: Muscle strengthening
Abdominal muscle strengthening exercises were given to both siblings once a day, 10 times a day, 5 times a week. In the supine position, the patients were asked to lie on their knees with the knees flexed. The hip extensors were trained in the prone position on the bed by resisting hip extension
Other: Balance and Coordination
The following exercises were applied 5 times a week, with 1o repetition once a day.
Standing on one leg in front of the mirror,
Tandem walking,
Rhythmic Dynamic Stabilization,
Swiss ball sitting (eyes open and closed),
Counting the alphabet or numbers while marching

Outcome Measures
Primary Outcome Measures
- Balance [6 weeks]
Balance and coordination will be evaluated with the Pediatric Berg Balance Test.
- Functional İndependence [6 weeks]
Functional independence which will evaluate with Functional Independence Measure for Children (WeeFIM).
- Observational Gait Analysis [6 weeks]
Gait characteristic will assessed with Observational Gait Analysis (OGA).
