PHTY302 Lecture Notes - Lecture 4: Strength Training, Biofeedback, Weight-Bearing
Document Summary
Paralysed / very weak muscles: grades 0-2, principles of strengthening differ from pre. Need low load/ high repetitions: aim: Structure training that allows for lots of repetitions to be achieved: how to elicit movement: Shorten / minimize impact of the lever arm. Visual cues to guide movement, prevent compensatory movements. Can have greater potential to initiate muscle activity in tasks related to muscle action. Modified walking ie treadmill and bodyweight. Weak muscles: grade 3-4, progressive resistance exercise, task related training. Increased speed of contractions: modified task practice includes. Use closed chain weight bearing position for extensor muscles. Use bodyweight to increase resistance to movement. Loss of coordination after stroke: the loss of skillful coordination of voluntary muscle activity to meet environmental demands, due to the loss of umn after stroke, characteristics: Coordination training after stroke: therapy needs to provide oppurtunities to practice task, reproduce timing and spatial demands of the task in contet of.
