Effects of Dual Task-Oriented Circuit Training on Walking Recovery in Sub-acute Stroke

This pilot study aims to assess the feasibility, safety, and initial efficacy of an integrated Dual Task-Oriented Circuit Training (DTOCT) program for individuals in the subacute phase of stroke recovery. Although numerous patients recover the capacity to walk in a regulated hospital environment, they frequently encounter difficulties with "community ambulation," the capability to traverse real-world settings while multitasking (e.g., walking while conversing or circumventing barriers). This study will examine if the integration of high-intensity circuit training with cognitive difficulties can promote neuroplasticity and enhance the patient's capacity to safely traverse intricate daily settings.

About this study

Cognitive-Motor Interference (CMI) makes it challenging for stroke survivors to reintegrate into their communities. Walking is an automatic subcortical process in a healthy brain. After a stroke, however, the brain often has to "consciously" control walking, which takes away mental resources from other tasks. This "functional gap" is why almost 80% of survivors can walk house-hold, but only 30% can safely get around in the community. This study examines the "Golden Window" of recovery (2 weeks to 5 months post-stroke), a timeframe characterized by optimal physiological conditions for neuroplasticity. The DTOCT protocol functions as a synergistic intervention: the circuit training induces cardiovascular intensity to stimulate systemic Brain-Derived Neurotrophic Factor (BDNF) release, while concurrent cognitive tasks (e.g., memory recall or the Stroop test) focus on localized neurotrophic support within the prefrontal cortex and hippocampus. This three-arm pilot study (DTOCT vs. pure task-oriented training vs. pure dual-tasking) will give us important information about how easy it is to recruit participants, how well they stick to the plan, and how big the initial effects are. These results will constitute an essential basis for an upcoming comprehensive Randomized Controlled Trial (RCT) designed to enhance the standard of neurorehabilitation in Indonesia.

Treatment and study plan

Dual task oriented circuit training

Behavioral
  • Experimental Arm: Dual Task-Oriented Circuit Training (DTOCT) Intervention Name: Behavioral: Dual Task-Oriented Circuit Training (DTOCT)

Description:

Participants will undergo an integrated 60-minute rehabilitation session, 3 times per week for 4 weeks (total 12 sessions). Each session includes 25-50 minutes of active circuit training across five specialized stations:

Dual-Task Walking: Straight walking (3-8m) while performing forward/backward number sequencing.

Obstacle Walking: Stepping over cone or hurdle obstacles (5-14cm) while naming object categories from long-term memory.

Stair Navigation: Ascending/descending stairs (10-17cm step height) while identifying colors and shapes.

Walking with Navigation: Navigating an oval path (3-8m) while performing an incongruent Stroop color-word task.

ADL Stimulation: Walking while carrying a cup of liquid or a shopping bag to train executive function and working memory.

Training intensity and cognitive difficulty are progressed weekly

Other names: DTOCT

Task Oriented Circuit Training

Behavioral
  • Active Comparator Arm: Task-Oriented Circuit Training (TOCT) Intervention Name: Behavioral: Task-Oriented Circuit Training (TOCT)

Description:

Participants will focus exclusively on functional motor relearning and cardiovascular endurance through 6 circuit-based stations:

Standing and Reaching: Multidirectional reaching to targets while standing. Sit-to-Stand: Transitions using chairs of various heights to strengthen extensors.

Anterior/Posterior Stepping: Stepping onto blocks of various heights. Lateral Stepping: Side-stepping for lateral stability. Forward Step-Up: Strengthening for stair climbing mechanics. Heel Raise: Improving gait push-off mechanics.

Each station is performed for 2.5 to 5 minutes with 1-minute rest periods. Training is conducted 3 times per week for 4 weeks (total 12 sessions), with each session lasting 60 minutes including warm-up and cool-down. No explicit secondary cognitive tasks are added.

Other names: TOCT

Dual Task Training

Behavioral
  • Active Comparator Arm: Pure Dual-Task Training (DT) Intervention Name: Behavioral: Pure Dual-Task Training (DT)

Description:

Participants will perform standard, non-circuit walking at a self-selected comfortable speed while executing simultaneous cognitive demands. The protocol includes:

Backward Counting: Continuous subtraction from a random 3-digit number. Stroop Task: Identifying font colors or semantic meanings of incongruent words. Memory Tasks: Sequential recall of shopping lists (3-5 items) and reverse word recall (2-4 words).

Verbal Fluency: Generating word chains or category naming.

Each session consists of two 15-minute sets of core dual-task training (30 minutes total activity) within a 60-minute therapist-supervised visit. Training is conducted 3 times per week for 4 weeks (total 12 sessions). Cognitive difficulty is adjusted weekly to maintain an optimal challenge.

Other names: DTT
