PHTY210 Lecture Notes - Lecture 11: Muscle Weakness, Proprioception, Myocyte
Document Summary
Formulate appropriate treatment plan: gait cycle: period of time during which a complete sequence of events takes place, terminology variations. Foot strike: heel strike, foot flat (ff) & loading response, grf absorption, weight acceptance, knee yield, late stance, terminal stance, early swing (esw) Lift off: late swing (lsw, terminal swing. Sagittal, frontal, transverse: kinetics, what causes what we see, examines the forces acting on a system, such as the human body, forces cannot be seen, but effects of forces can be observed. Internal forces: muscle forces, the muscle activity required is often to brake or control the motion of the body parts as well as generate movement. Ligaments/other soft tissue forces: tension generated in stretched tissue such as ligaments, joint capsule, external forces. Inertial forces due to acceleration of body segment e. g. swinging leg: gravity, weight of the body segment e. g. weight of the foot, ground reaction force. Forces acting between the foot and ground (surface: newton"s law of action-reaction.
