In clinical practice, muscle weakness is often considered a functional disability similar to limitation of range of motion. Physical therapists use manual muscle testing (MMT) as described by Daniels et al. for the general assessment for muscle weakness. This test quantitatively assesses muscle strength by the amount of joint movement, muscle contraction, and the effect of gravity and resistance. However, it is not possible to evaluate the strength of individual muscles involved in a single joint movement, or to separate a single muscle into fibers with different actions when using this method. It is also difficult to assess qualitatively whether muscle activity is assessed at a specific time during movement. In this paper, we examine the possibility of evaluating muscle weakness using MMT for knee extension, hip extension, and hip abduction by changing some of the test positions and the direction of manual resistance based on kinematics. For knee extension, we describe how to check the alignment of the patella and how to vary the movement speed to check for muscle activity at a given time. Each of these approaches are presented based on electromyogram data.
