Detailed Description
Effective evaluation and treatment for lower extremity (LE) motor and function recovery in patients with stroke have been one of the primary goals for rehabilitation therapy. The purposes of this study are to compare immediate and long-term treatment effects among noxious cold only, noxious heat only, and alternative thermal stimulation (TS) on the LE motor recovery and neuromuscular properties and to investigate the relationships among spinal circuit excitability, muscle properties, and motor function of LE in patients with chronic stroke.
This 3-year study will recruit a total of 72 subjects with first-ever stroke after 3 months onset from the department of Physical Medicine and Rehabilitation in 3 teaching hospitals. This study design employs a prospective single-blinded, randomized controlled trial with pretest, posttest, and follow-up assessments. Participants who meet and be willing to join this study will be assigned into one of three groups (noxious cold only, noxious heat only, or alternative TS). All subjects will receive conventional rehabilitation. In addition, three groups will receive an additional TS protocol with a total of 15 sessions for 3 weeks (5 times per week, 30 minutes daily). Primary outcome measures include the LE subscale of Fugl-Meyer assessment, the modified Ashworth scale, the Postural Assessment Scale for Stroke Patients, Timed Up and Go test, and the Barthel index. Moreover, spinal circuit excitability will be assessed by measuring Hoffmann reflex/ M wave ratio, H-reflex recruitment curves, and reciprocal inhibition of the soleus muscle. Muscle properties will be evaluated by measuring the soleus muscle tone, elasticity, and stiffness. All participants will be assessed with the outcome measures at one week before the intervention, beginning of the intervention, the end of the intervention, 1 month and 3 months after the intervention. A two-way repeated measures analysis of variance will be used to investigate the effects among the three groups across time points tested with adequate post-hoc comparisons.
The results of this study will help to understand the immediate and long-term effects of motor recovery of different TS modes and the adaptive change of neuromuscular properties as well to select the more effective TS treatment mode on facilitating LE motor and function recovery in patients with stroke.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: noxious cold group
The group received noxious cold (3 - 4°C) stimuli on the affected leg for 30 minutes.
|
The protocol included range of motion, ambulation, endurance, strengthening, reconditioning exercise, and home program education according to therapists' plans and the patients' ability.
|
Active Comparator: noxious heat group
The group received noxious heat (46 - 47°C) stimuli on the affected leg for 30 minutes.
|
The protocol included range of motion, ambulation, endurance, strengthening, reconditioning exercise, and home program education according to therapists' plans and the patients' ability.
|
Active Comparator: alternative thermal stimulation group
The group received alternative noxious heat (46 - 47°C) and noxious cold (3 - 4°C) stimuli on the affected leg for 30 minutes.
|
The protocol included range of motion, ambulation, endurance, strengthening, reconditioning exercise, and home program education according to therapists' plans and the patients' ability.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The Lower Extremity subscale of Fugl-Meyer assessment (FMA-LE)
Time Frame: Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
The FMA-LE consists of 17 items, each scored on a 3-point scale (0 to 2).
The total score of the FMA-LE ranges from 0 to 34, and higher scores indicate better motor performance.
|
Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
The Postural Assessment Scale for Stroke (PASS)
Time Frame: Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
The PASS is a 4-point rating (0 to 3) scale with well-established reliability and validity that measures balance function in persons with stroke.
The total score of the PASS ranges from 0 to 36, and higher scores indicate greater balance function.
|
Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
The modified Ashworth scale (MAS)
Time Frame: Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
The modified Ashworth scale is a 6-point rating scale (0 to 5) with well-established inter-rater reliability that measures muscle tone of ankle plantarflexor in persons with stroke.
Higher MAS scores indicate greater severity of spasticity.
|
Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
The Barthel index (BI)
Time Frame: Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
The Barthel index is used to evaluate activity of daily living function.The Barthel index consists of 10 items.
The total score of the Barthel index ranges from 0 to 20, and higher scores indicate better outcome.
|
Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
Timed up and go test(TUG)
Time Frame: Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
The Timed Up and Go (TUG) test assesses mobility by measuring the time it takes for someone to stand, walk a short distance, turn, and sit back down.
Faster times suggest better mobility, while longer times may indicate mobility limitations or fall risk.
It's a useful tool to evaluate functional capacity and guide interventions for improved mobility.
|
Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.

Higher scores indicate poorer outcome.
|

Time Frame: Change from the beginning of the intervention to the end of the intervention, 1 month and 3 months after the intervention.
|
Muscle properties will be evaluated by measuring the soleus muscle stiffness.
