Motor System: Tone

Motor System

Tone

BACKGROUND

Testing muscle tone is a very important indicator of the presence and site of pathology. It can be surprisingly difficult to evaluate.

WHAT TO DO

Ensure the patient is relaxed, or at least distracted by conversation. Repeat each movement at different speeds.

Arms

Take the hand as if to shake it and hold the forearm. First pronate and supinate the forearm. Then roll the hand round at the wrist (Fig. 16.1).

Figure 16.1 Roll the wrist

Hold the forearm and the elbow and move the arm through the full range of flexion and extension at the elbow.

Legs

Tone at the hip

The patient is lying with straight legs. Roll the knee from side to side (Fig. 16.2).
