Study summary

The study team is recruiting 20 adults with spasticity due to chronic stroke for a 7 day study over 2 weeks. In people with chronic stroke, one of the most common and disabling problems is spasticity (increased muscle tone or muscle stiffness). The purpose of this research study is to examine effects of dry needling on the nervous system (pathways between the muscle, spinal cord, and brain) in people with spasticity due to chronic stroke. Dry needling is a procedure in which a thin, stainless steel needle is inserted into the skin to produce a muscle twitch response. It is intended to release a knot in the muscle and relieve pain.

The total study duration is 7 visits over 2 weeks. There will be 4 visits the first week, and 3 visits the second week. The first visit will take about 1.5 hours, during which study staff will determine the best placement of electrodes and create a cast of the participant's leg to aid them in quickly placing the electrodes on the remainder of the visits. The second and fifth visits will last about 3.5 hours, and all other visits will last about 1.5 hours. Dry needling will take place on the fifth visit only. During each visit the participant will be asked to participate in examinations of reflexes (muscle responses to non-invasive nerve stimulation) and leg function.

Study arms

  • Experimental
    Single Arm

    All participants completed 2 weeks of the study. Baseline reflex measurements will be collected during the first week of the study (Visits 1-4). No dry needling will occur during this week, with the aim of tracking any natural variability in nervous system excitability at the same time points as reflex measurements during the intervention week. All participants who participated in baseline reflex measurements during week 1 will continue to the second week of the study (Visits 5-7). Participants will receive dry needling to relieve spasticity in the target calf muscle (middle gastrocnemius) during Visit 5. The study team will examine the effects of this treatment on the nervous system by performing assessments just prior to DDN, immediately after DDN, 90 minutes after DDN, 24 hours after DDN, and 72 hours after DDN. These assessments will examine how you move your leg and how your nervous system responds to non-invasive nerve stimulation.

What researchers measure

Primary outcomes

  1. Changes in the H-reflex Amplitude in Response to Nerve Stimulation

    H-reflex amplitude (mV) reflects the excitability of its reflex pathway. Changes in the H-reflex amplitude indicate that DDN influences the spinal excitability. This will be measured in the tibialis anterior and the triceps surae.

    Time frame: 7 days prior (2 time points), 6 days prior, 4 days prior, baseline, immediately after DDN, 90 minutes after DDN, 24 hours after DDN, and 72 hours after DDN

  2. Changes in Cutaneous Reflexes Elicited by Non-noxious Stimulation of Cutaneous or Mix Nerves

    Changes in the cutaneous reflex amplitudes would indicate that DDN can influence the spinal processing of cutaneous information.

    Time frame: 7 days prior (2 time points), 6 days prior, 4 days prior, baseline, immediately after DDN, 90 minutes after DDN, 24 hours after DDN, and 72 hours after DDN

  3. Changes in Perception of Cutaneous Stimuli as Measured by Perception and Radiating Threshold of Cutaneous Nerve Stimulation

    Changes in the cutaneous reflex amplitudes would indicate that DDN can influence the spinal processing of cutaneous information.

    Time frame: 7 days prior (2 time points), 6 days prior, 4 days prior, baseline, immediately after DDN, 90 minutes after DDN, 24 hours after DDN, and 72 hours after DDN

  4. Ability to Move the Limb as Measured by Range of Motion (ROM)

    ROM is measured in degrees using a standard goniometer. ROM will be measured both passively (moved by the assessor) and actively (participant moves the leg themselves) and the value reported is the maximum degree of dorsiflexion in each condition. Positive values indicate degrees of dorsiflexion beyond neutral, negative values indicate degrees of plantarflexion. Greater values indicate greater degrees of dorsiflexion.

    Time frame: Timepoints are defined as baseline, 0-minutes post, 90 minutes post and 72 hours post DDN during intervention week and the corresponding 4 timepoints the week prior (non-intervention) but without DDN.

Secondary outcomes

  1. Ability to Move the Leg as Measured by the Fugl-Meyer Assessment (FMA) Lower Extremity

    An increase in the FMA-LE score indicates better movement of the leg. Score ranges from 0 - 34.

    Time frame: Timepoints are defined as baseline, 0-minutes post, 90 minutes post and 72 hours post DDN during intervention week and the corresponding 4 timepoints the week prior (non-intervention) but without DDN.

  2. Change in Spasticity as Measured by the Modified Ashworth Scale (mAS)

    The mAS score ranges from 0: normal muscle tone to 4: rigid in flexion or extension. A decrease in mAS indicates decreased spasticity. A score of 1.5 reported below is equal to 1+ on the mAS

    Time frame: baseline, immediately after DDN, 90 minutes after DDN, 24 hours after, and 72 hours after DDN

  3. Change in Pain Level as Measured by the Visual Analog Scale (VAS) for Pain

    Pain is rated by the participant on a scale from 0 (no pain) to 10 (worst pain imaginable). Decreased score on the VAS for pain indicates decreased pain.

    Time frame: 7 days prior (2 time points), 6 days prior, 4 days prior, baseline, immediately after DDN, 90 minutes after DDN, 24 hours after DDN, and 72 hours after DDN

  4. Change in Time Needed to Walk 10 Meter (10 m Walk Test)

    Decreased time indicates improved ability to walk

    Time frame: Timepoints are defined as baseline, 0-minutes post, 24 hours post and 72 hours post DDN during intervention week and the corresponding 4 timepoints the week prior (non-intervention) but without DDN.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2022 to primary completion in Jun 2023, 15 months.

Results were first posted in Nov 2024, 1 year 5 months after primary completion.

Of 2,859 non-industry interventional studies with no phase under Stroke, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 45. This study's 15 months is below that.

Counting every sponsor, half of 2,988 studies reached it within 23 months; a quarter within 10 and three quarters within 45.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 20, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
