Outcome Measures

Primary Outcomes (1)

  • change in spastic paraplegia rating scale(SPRS)

    demonstrate the statistically significant improvement in score of spastic paraplegia rating scale(SPRS) from baseline( Off medication) to 12 months(On stimulation/Off medication); The score of SPRS ranges from 0 to 52, higher scores mean a worse outcome .

    twelve months after surgery

Secondary Outcomes (5)

  • change in the score of Modified Ashworth Scale

    twelve months after surgery

  • change in Activities of Daily Living Scale (ADL)

    twelve months after surgery

  • change in Tinetti Balance and Gait Analysis

    twelve months after surgery

  • change in Berg Balance Scale(BBS)

    twelve months after surgery

  • Clinical Global Impression-Global Improvement

    twelve months after surgery

Study Arms (1)

Spinal cord stimulation therapy

EXPERIMENTAL

Spinal cord stimulation at the thoracic levels ranging from T10 to T12.

Procedure: Spinal cord stimulation

Interventions

Paddle-shaped Spinal cord stimulation electrode with 16 contacts (AdaptiveStim® 39, 565;Medtronic, USA) will be implanted into the epidural space at the thoracic levels ranging from T10 to T12.

Spinal cord stimulation therapy

Eligibility Criteria

Age14 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • aged between 14 and 70 years
  • patients with pure hereditary spastic paraplegias
  • with progressive weakness and spasticity of the lower limbs, and the gait dysfunction treatable by medication but not adequately controlled with medications
  • Understand potential risk/benefit, consent to the study, study procedures, and agree to complete the study follow-up visits and comply with the study protocol requirements.

You may not qualify if:

  • cognitive impairment ( MMSE≤24), depression (HAMD\>24),acute psychosis, active alcohol or drug abuse, terminal illness, and any major medical or psychological histories, diagnoses, conditions, or comorbidities that would interfere with participation in the study per the investigatior's medical judgment
  • surgical or medical contraindications to spinal cord stimulation surgery(e.g. uncontrolled hypertension, advanced coronary artery disease).
