Representative electromyography (EMG) profiles and foot contact patterns. EMG profiles are normalized to the gait cycle. Exceptions to the typical patterns are noted with an asterisk: his right rectus femoris varied from continuously active, to active from initial swing through midswing and in loading response (as shown); his right medial hamstrings had continuous activity at ages 6 and 7 years, following which it was active from terminal swing through loading response with additional activity from preswing to initial swing (as shown). ofto opposite foot toe-off, ofc opposite foot contact, TO toe-off
