Hereditary Spastic Paraplegia
Conditions
Brief summary
There are limited but encouraging results supporting the use of dalfampridine in patients with hereditary spastic paraplegia. The investigators aimed to investigate the effects of dalfampridine on walking speed, muscle length, spasticity, functional strength, and functional mobility in patients with hereditary spastic paraplegia. In this triple-blinded, randomized, placebo-controlled trial, 4 patients with hereditary spastic paraplegia received dalfampridine (10 mg twice daily) plus physiotherapy (2 times per week), and 4 patients received placebo plus physiotherapy for a total duration of 8 weeks. The assessor and treating physiotherapists, and patients were masked to the group allocation. The primary outcome was Timed 25-foot Walk Test at the end of the 8-week treatment. The secondary outcome measures were functional mobility, functional muscle strength, muscle length, and spasticity.
Interventions
DRUGDalfampridine 10 MG
The participants in the experimental group received dalfampridine administered as 10 mg extended-release tablets every twelve hours for 8 weeks.
DRUGPlacebo
Control group received a placebo drug with the same administration method (2 times per week for the total duration of 8 weeks).
BEHAVIORALPhysiotherapy
Conventional physiotherapy program including stretching and flexibility, strengthening, walking and balance exercises which were mainly focused on the lower limbs and improving walking. The program was applied 2 times per week for the total duration of 8 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Timed 25-foot Walk Test | Change from baseline to week 8 | The Timed 25-foot walk test (T25FW) is considered the best characterized objective measure of walking disability and can be used across a wide range of walking disabilities. For the T25-FW, patients were instructed to walk as fast as they could in a safemanner along amarked 25-foot course. The time in seconds to complete each test was recorded, and the test was immediately repeated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sit to Stand Test | Change from baseline to week 8 | 30 second Chair-Stand Test which is a reliable and valid measure used to assess lower extremity strength and endurance is used where the number of sitting and getting up within 30 seconds gives the score of the test. |
| Timed Up and Go test | Change from baseline to week 8 | Functional mobility was evaluated using the Timed up and Go Test 'TUG' test, which is also reliable and valid test for people with Parkinson's disease. (Morris2001; Van2016). Upon issuing the command Go, the participants stood up from a normal chair, walked 3 meters, turned, walked back to the chair, and sat. The time began with the command Go and ended when the participants sat back to the chair. This test was repeated three times, and the shortest performance time was recorded |
| Modified Ashworth Scale | Change from baseline to week 8 | Modified Ashworth Scale (MAS) is one of the reliable and valid methods to measure muscle spasticity. The procedure to evaluate specific muscle groups; passively moved through the range of motion of a limb, and the resistance encountered during muscle stretch is rated on a five-point scale. Ashworth defines this rating as; 0 = no increase in tone, 1 = slight increase in tone at the end of the range of motion, 1+ = slight increase in tone throughout less than half the range of motion, 2 = increased muscle tone throughout the full range of motion, but passive movement is present. 3=tone movement that makes passive movement difficult, 4=rigidity . |
| Muscle Length Measurement | Change from baseline to week 8 | Bilateral muscle length measurements were obtained using a standard goniometer. The patient positioned in supine position; the dorsiflexion has been tested for the gastrocnemius, the straight leg rise - hip angle has been measured to assess hamstrings, the Thomas test was used to assess iliopsoas and hip abduction angle was used for adductor group muscles. |
