About this study

Official title: The Effects of Transcutaneous Spinal Cord Stimulation on Upper Extremity Function in Children and Young People With Hemiplegic Cerebral Palsy

This work will examine if a technique called Transcutaneous Spinal cord stimulation (tSCS), when used with concurrent specific arm and hand exercises, helps improve arm and hand movements in CYP with HCP.

Does Transcutaneous Spinal Cord Stimulation (tSCS), when combined with specific arm and hand exercises, improve upper limb function in children and young people (CYP) with Hemiplegic Cerebral Palsy (HCP)?

-To determine the feasibility and effectiveness of Transcutaneous Spinal Cord Stimulation (tSCS) combined with targeted arm and hand exercises in improving the upper limb function in children and young people with Hemiplegic Cerebral Palsy (HCP).

Read the detailed description

Cerebral palsy (CP) is a condition that affects movement and posture due to brain development issues in babies or young children. Hemiplegic CP (HCP) is a condition where one side of the body is paralysed. Symptoms like stiffness in the arms and legs usually appear early and can make everyday tasks, such as reaching or holding objects difficult. Improving arm and hand function is crucial for increasing independence and quality of life for children with HCP. This study investigates a technique called Transcutaneous Spinal Cord Stimulation (tSCS). tSCS uses sticky pads placed on the skin to deliver a mild electrical current. This current stimulates nerves to help them send signals to the muscles, potentially improving arm and hand movements. Research has demonstrated that tSCS can provide benefits in the lower limb for children and young people (CYP) with CP, those with spinal cord injuries and healthy individuals. In this project, we will test the feasibility and effectiveness of tSCS in 18 CYP (aged 12-21 years) with HCP. The participant will attend two sessions. Each session will last approximately 60-90 minutes and will include:

  • A Baseline Assessment (before training)
  • A 30-minute Upper Limb Task Training (ULTT)
  • One session will involve transcutaneous spinal cord stimulation (tSCS) combined with ULTT
  • One session will involve ULTT only (no stimulation)
  • The order is randomised, meaning participants do the stimulation session first or second
  • A Post-Training Assessment

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Participants with stimulation-site skin reaction (Yes/No; photographic assessment)

    Standardised photographs of the back will be obtained at each time point and reviewed by an independent clinician (not part of the study team). A skin reaction is defined as any visible erythema at/near the electrode site and will be recorded on a Yes/No erythema scale (0 = No erythema; 1 = Yes erythema). Results will be reported as the number and proportion of participants with ≥1 skin reaction during the session and by time point.

    Measured: At the first session: Baseline (pre-tSCS) and immediately post-tSCS

  2. Heart Rate Category (beats per minute)

    Heart rate will be measured immediately before and after tSCS using an OMRON M3 device. For each participant, a blinded independent clinician will classify the post-stimulation change relative to Baseline as one of three categories: Increased, Decreased, or No Apparent Change. Study results will be summarised as the number and proportion of participants in each category and described narratively.

    Measured: [Time Frame: Baseline (pre-tSCS); During tSCS (10 minutes after start); Immediately post-tSCS (within 10 minutes after end) during a single session.

  3. Hand Strength Index (dynamometry)

    Handgrip and pinch strength will be measured with handheld dynamometers (adjustable handle/pads; peak-hold). At each time point, participants perform 3 maximal attempts per measure; the average (mean) is calculated for handgrip and for pinch. Results will be summarised as mean (SD) by timepoint and change from pre to post within each session (Post - Pre). Component means (handgrip and pinch) will be presented descriptively as supportive information.

    Measured: Session 1[first visit]: Pre (Baseline, before tSCS); Session 1 [first visit]: Post (immediately after tSCS, within 10 minutes); Session 2 [second visit]: Pre (Baseline, before tSCS); Session 2 [sv]: Post (immediately after tSCS, within 10 minutes)

  4. Jebsen-Taylor Hand Function Test total time (seconds)

    Hand function will be assessed with the Jebsen-Taylor Hand Function Test (JTHFT). The protocol includes three subtests: (1) picking up small common objects; (2) stacking checkers; (3) lifting large light and large heavy cans (~1 lb). Each subtest is timed to completion. Testing is administered with the less affected hand first, then the more affected hand; the primary outcome is the Total Score for the more affected hand. Results will be summarised as mean (SD) seconds by timepoint and change from pre to post within each session (Post - Pre). (Scores for the less affected hand may be presented descriptively as supportive data.)

    Measured: Session 1[first visit]: Pre (Baseline, before tSCS); Session 1 [first visit]: Post (immediately after tSCS, within 10 minutes); Session 2 [second visit]: Pre (Baseline, before tSCS); Session 2 [sv]: Post (immediately after tSCS, within 10 minutes)

  5. Muscle Activity: Mean motor threshold to elicit ≥50 µV sEMG response (mA) - Delsys Trigno / Digitimer DS8R

    Muscle activity will be assessed with surface EMG (Delsys Trigno). Sensors will be placed on the more affected arm over the abductor pollicis brevis, flexor carpi radialis, and extensor carpi radialis longus. Single spinal pulses (1 ms biphasic square-wave) will be delivered every ~5 s using a Digitimer DS8R. For each muscle at each time point, the motor threshold is defined as the lowest stimulation amplitude (mA) that produces an evoked sEMG response ≥50 µV. The participant-level outcome is the mean motor threshold (mA) across the three muscles. Results will be summarised as mean (SD) mA by timepoint and change from Baseline to Post.

    Measured: Session 1: Pre (Baseline, before tSCS); Session 1: Post (immediately after tSCS, within 10 minutes); Session 2: Pre (Baseline, before tSCS); Session 2: Post (immediately after tSCS, within 10 minutes).

  6. Modified Ashworth Scale (0-4; higher = worse) - worst upper-limb muscle score (more affected limb)

    Spasticity will be assessed with the Modified Ashworth Scale (MAS), scored 0, 1, 1+, 2, 3, 4 (0 = no increase in tone; 4 = rigid; higher scores indicate worse spasticity). The following muscles on the more affected upper limb will be tested in a fixed order: elbow flexors, wrist flexors, finger flexors. At each timepoint, the primary outcome is the worst (highest) MAS score across the tested muscles. Results will be summarised as median by timepoint and change from Pre to Post within each session (Post - Pre).

    Measured: Session 1[first visit]: Pre (Baseline, before tSCS); Session 1 [first visit]: Post (immediately after tSCS, within 10 minutes); Session 2 [second visit]: Pre (Baseline, before tSCS); Session 2 [sv]: Post (immediately after tSCS, within 10 minutes)

  7. Systolic Blood Pressure Category (mmHg)

    Systolic blood pressure will be measured immediately before and after tSCS using an OMRON M3 device. For each participant, a blinded independent clinician will classify the post-stimulation change relative to Baseline as one of three categories: Increased, Decreased, or No Apparent Change. Study results will be summarised as the number and proportion of participants in each category and described narratively.

    Measured: Baseline (pre-tSCS); During tSCS (10 minutes after start); Immediately post-tSCS (within 10 minutes after end) during a single session.

  8. Diastolic Blood Pressure Category (mmHg)

    Diastolic blood pressure will be measured immediately before and after tSCS using an OMRON M3 device. For each participant, a blinded independent clinician will classify the post-stimulation change relative to Baseline as one of three categories: Increased, Decreased, or No Apparent Change. Study results will be summarised as the number and proportion of participants in each category and described narratively.

    Measured: Baseline (pre-tSCS); During tSCS (10 minutes after start); Immediately post-tSCS (within 10 minutes after end) during a single session.

Secondary outcomes (2)
  1. Participant-reported experience with stimulation - response frequencies (project-specific questionnaire)

    A project-specific Participant Feedback Questionnaire (PFQ-tSCS), completed by the participant or caregiver, will capture experience with stimulation across predefined domains: comfort, ease of participation, sensations during the session, skin reactions, discomfort/adverse effects, and overall satisfaction. Items use ordered categorical response options (e.g., None/Mild/Moderate/Severe or Strongly disagree → Strongly agree), plus optional free-text. Outcome data will be reported as the number and proportion of participants in each response category for each item; free-text responses will be summarised narratively.

    Measured: Immediately post-final tSCS session [first session] (within 10 minutes), single administration.

  2. ABILHAND-Kids total raw score (0-42; higher = better manual ability)

    Manual ability will be assessed with the ABILHAND-Kids Questionnaire (21 items; response options: Impossible = 0, Difficult = 1, Easy = 2). The total raw score is the sum across items (higher scores indicate better manual ability). The questionnaire may be completed by the participant or a caregiver proxy per instrument guidance. Results will be summarised as mean (SD) total score by timepoint and change from Pre to Post within each session (Post - Pre)

    Measured: Session 1[first visit]: Pre (Baseline, before tSCS); Session 1 [first visit]: Post (immediately after tSCS, within 10 minutes); Session 2 [second visit]: Pre (Baseline, before tSCS); Session 2 [sv]: Post (immediately after tSCS, within 10 minutes).
