NCT03421509

Brief Summary

The cutaneous silent period (CSP) is a brief transient suppression of the voluntary muscle contraction that follows a noxious cutaneous nerve stimulation. Studies in patients with central disorders of motor control such as dystonia and Parkinson's disease have shown CSP abnormalities indicating that supraspinal pathways influence this inhibitory spinal reflex. The aim of this study is to investigate the association between CSP parameters (duration and latency) and spasticity in stroke.

Outcome Measures

Primary Outcomes (2)

  • Cutaneous silent period latency (ms)

    the brief interruption in voluntary contraction that follows strong electrical stimulation (painful) of a cutaneous nerve. time between the stimulation and beginning of the silent period.

    Day 1

  • Cutaneous silent period duration (ms)

    the brief interruption in voluntary contraction that follows strong electrical stimulation (painful) of a cutaneous nerve. CSP duration is defined as the time between the beginning and endpoint of the silent period

    Day 1

Secondary Outcomes (14)

  • Modified Ashworth Scale wrist

    Day 1

  • Modified Ashworth Scale finger flexors

    Day 1

  • Modified Tardieu Scale R1 wrist

    Day 1

  • Modified Tardieu Scale R1 finger flexors

    Day 1

  • Modified Tardieu Scale R2 wrist

    Day 1

  • +9 more secondary outcomes

Interventions

In the upper limb the cutaneous silent period (CSP) is a brief transient suppression of the voluntary muscle contraction that follows painful stimulation applied to the finger (digits II-V, C6-C8 dermatomes)
