Lower Limb Motor Coordination
Original Editor - Joseph Olamide
Introduction[edit | edit source]
Motor coordination, otherwise referred to as dexterity, refers to the ability to perform a motor task in an accurate, rapid and controlled manner. Coordination is dependent on interactions within feedforward and feedback mechanisms between the central nervous system (CNS), sensory information, body schema and motor control . For motor control, sufficient muscle tone, range of movement and strength are required. Within the CNS, the cerebellum is primarily is responsible for coordination. Motor coordination requires temporal and spatial accuracy.
Lower limb motor coordination is essential for the performance of most daily motor activities, such as walking, running, ascending/descending stairs and standing from a chair. The effective performance of these tasks are critical for an independent life. Impaired coordination impacts on strength, speed and precision of lower limb movement, thus affecting these functions . It is also important for community activities, and it’s limitation may cause people to become housebound and isolated from the society, especially for those who had suffered stroke. Motor tasks performed within different contexts require between-limb coordination, which is essential for an independent and safe life, especially in elderly individuals. Lower limb joint coordination changes with age, increasing the risk of falls in the elderly population. Adequate lower limb motor coordination significantly contributes to functionality of stroke individuals, its loss is the major contributor to disability in this population . Thus, therapeutic approaches aimed at restoring lower limb motor coordination are of great interest for rehabilitation professionals who are involved in research and clinical settings.
Medical conditions that may exhibit deficits in lower limb motor coordination[edit | edit source]
Assessment of lower limb motor coordination[edit | edit source]
Lower limb motor coordination evaluation is very important for a physical therapist practice, as it enables the understanding of the nature and level of impairments of the individual in a standardized way . The information gathered from the assessment tools may help planning the interventions and monitoring the clinical status of the patients before, during, and after physical therapy interventions .
- Auditory-paced ankle dorsi and plantarflexion task
- Rapid alternating movement patterns test (RAMP)
- Lower Extremity Motor Coordination Test (LEMOCOT)
- Comprehensive Coordination Scale
- Heel-Shin Test
