Calf Muscle Contraction During Walking

Overview

Walking is the most familiar form of exercise, the calf muscle plays an important role in the stance phase of the normal gait cycle of gait. The relative contribution of the calf muscle to the total positive work of the lower extremities during walking is approximately 51% and 73% in the elderly and younger people respectively. This study will explore the different types of calf muscle activation during normal gait cycle based on the previous literature and will introduce a new proposition in the biomechanics of calf muscle contraction..Also, this study will address the role of this muscle during gait and the effects of calf muscle weakness on the lumbar spine.

400 patients with a history of calf muscles' weakness throughout the last 3 years will be included in the study. The patients suffered from unresolved CLBP with radiculopathy contralateral to their calf muscle atrophy (i.e., an ipsilateral calf muscle weakness induces contralateral lumbar radiculopathy) that did not respond to physical therapy or any medication for long patients in an out-patient clinic in Egypt (2016 to 2022) are screened for calf muscle weakness secondry to ankle injury. Patients with lumbar disc herniation (confirmed by MRI) and radiculopathy contralateral to the calf muscle weakness are recruited to participate in this study A better understanding of the calf muscle contraction can provide a valuable insight into how the calf muscle works during walking, predict calf muscle injuries and develop specific exercise to enable the patients with calf muscle dysfunction. …………………………………………………………………………………………………………………
