Pedaling exercises improve gait in patients with stroke and stiff knees

This study investigated the effectiveness of pedaling exercises on gait disorders in patients with stroke. Researchers suggested that pedaling improves knee movement and gait disorders in these patients.

A stroke happens when the blood flow to the brain is cut off due to a blood clot or hemorrhage. The brain cells stop receiving oxygen and begin to die. These cells lose the ability to control body functions leaving the patients with symptoms such as gait disabilities. Stiff-knee gait is a common gait disorder in these patients. It consists of a reduced movement of the knee joints while walking. This leads to impaired foot clearance, toe dragging, and increased risk of falls. Good and safe treatments for these patients are still missing.  

Pedaling exercises are commonly used in physical rehabilitation in patients with stroke. Prior studies suggested that pedaling improves muscle re-education. However, the effectiveness of pedaling in the treatment of stiff-knee gait disorder is not clear.

This study included information about 21 patients with stroke and stiff-knee gait. These patients were randomly assigned to receive pedaling or walking rehabilitation treatment.

The pedaling group reported better leg movements with faster knee and hip joint function. These patients showed increased step length and gait speed.  

This study concluded that pedaling improves the outcomes of gait disorders in patients with stroke.

This study did not evaluate the effect of regular pedaling for stiff-knee gait. This could lead to a significant improvement in walking performance and change the results. It also included a very small number of participants. Further larger studies are needed.
