Immediate Effects of Ankle Binder on Hip and Knee Range of Motion in Swing Phase in Sagittal Plane of Acute Stroke Patients: An Experimental Study
Main Article Content
Abstract
Background: Stroke is a neurological dysfunction related acute focused injury of the central nervous system by a vascular source, leading to over 50% of them having long-term disabilities and need aid with carrying out daily duties. Hemiplegic gait is mostly caused by foot drop brought on by stiff plantar flexors, weak dorsiflexors, and increased spasticity. When a patient is unable to dorsiflex their ankle joint during the swing phase, it is commonly referred to as foot drop. Ankle binder which is often used to stabilize the ankle in chronic ankle instabilities and sprains will provide stability as well as functional mobility without endangering neuromuscular deconditioning. The ankle binder has a reduced surface area in contact with the skin compared to standard AFOs, making it more effective in delivering input to the proprioceptive senses which might also improve gait in hemiplegic patients by affecting hip and knee range of motion. Therefore, the objective of the study is to compare the immediate effects of ankle binder on hip and knee range of motion in swing phase in sagittal plane of acute stroke patients using the Kinovea Motion Analysis Software
Methodology: The present study type is One-Group Pretest-Posttest Experimental study. A total of 67 patients having unilateral stroke were selected using purposive sampling. Pre intervention gait was recorded, post intervention was carried out by strapping ankle binder to the foot in dorsiflexion with eversion position and gait was recorded with smartphone. Frames/Sections were taken in Early swing phase (for Hip Extension), Midswing phase (for Hip and Knee Flexion) and Late swing phase (for Knee Extension) for range of motion analysis. The pre-post measurement data was analyzed with the help of Kinovea Motion Analysis Software and statistical analysis was done
Results: The present study showed a significant improvement in the hip flexion, knee flexion and knee extension range of motion with a p value < 0.0001. While no significant improvement in hip extension range of motion with p = 0.116 in swing phase in sagittal plane of acute stroke patients.
Conclusion: The present study concludes that there was significant improvement in hip flexion, knee flexion and knee extension range of motion but no significant improvement in hip extension range of motion in swing phase when seeing the immediate effects of ankle binder on hip and knee range of motion in swing phase in sagittal plane of acute stroke patients
