Final answer:
The normal range of motion (ROM) for gait in the hip joint depends on various factors, but on average, flexion is about 120 degrees, extension is about 30 degrees, abduction is about 45 degrees, and adduction is about 30 degrees.
Step-by-step explanation:
The normal range of motion (ROM) necessary for gait in the hip joint depends on various factors such as age, fitness level, and individual variations. However, on average, the normal ROM for hip joint flexion (bringing the knee towards the chest) is about 120 degrees, while the normal ROM for hip joint extension (bringing the leg back) is about 30 degrees. The normal ROM for hip joint abduction (moving the leg away from the midline) is about 45 degrees, and the normal ROM for hip joint adduction (moving the leg towards the midline) is about 30 degrees.
