decrease abductor force
|

|
decrease joint reaction force
|
Detailed explanation-1: -Peak hip joint reaction forces varied from 0.5 to 9 times body weight. Sit to stand produced the greatest average peak reaction force in excess of 6 body weight to generate lift without the use of arms. Kneel reach produced the lowest hip reaction forces ∼0.5 body weight.
Detailed explanation-2: -The main flexors of the hip joint are the iliopsoas muscle (psoas major and iliacus) and the rectus femoris muscle. The pectineus, tensor fasciae latae and sartorius muscles assist as weak flexors. Also, the adductor longus and brevis can assist with flexion of the hip joint in addition to its adductor function.
Detailed explanation-3: -Limping (antalgic gait) Using a cane in the opposite hand-this reduces the joint reaction force by 50% when approximately 15% of body weight is applied to the cane.
Detailed explanation-4: -Rest. Therapeutic heat and icing. Gentle exercise or stretching. Medications to treat inflammation. Weight loss.
