Summary
This case study shows that combining task-specific and lower extremity (LE) strength training improved walking speed and function in a stroke survivor. These gains were linked to enhanced muscle activation and better hip and knee movement during gait.
Area of Science:
- Neurorehabilitation
- Movement Science
- Clinical Case Study
Background:
- Task-specific training and strength training are effective post-stroke interventions.
- This case study explores a combined therapy approach for a stroke patient.
- Investigates potential mechanisms of neurologic recovery and intervention response.
Observation:
- A 38-year-old female with a right middle cerebral artery stroke, 15 months post-onset, participated.
- The participant used an ankle-foot orthosis and cane for ambulation (0.50 m/s free, 0.62 m/s fast).
- A 6-week program involved alternating body-weight supported treadmill training and limb-loaded cycling (24 sessions).
Findings:
- Post-treatment, walking speed increased by 18% (free) and 14.4% (fast).
- Six-minute walking distance improved by 4% (184.4 m), with sustained gains at 6 months.
- Gait analysis showed increased paretic leg gluteus maximus/medius activation and improved hip/knee extension during gait.
Implications:
- Combined task-specific and lower extremity (LE) strength training yielded clinically meaningful improvements in walking function.
- Enhanced motor unit activation and strength in key gait muscles may underlie therapeutic response.
- This approach offers a potential strategy for post-stroke motor recovery.
