UNIT Date Check Your Understanding REVIEW Critical Thinking and Application Questions 1 Muscle strain, or "pulling a muscle," may result from overuse injuries or from trauma, Typically muscle strain results in pain around the muscle with movement and with pressure. Predict which muscle or muscles may be strained from pain in each of the following locations: a Lateral thigh b Posterior arm c Lateral neck. d Abdomen just medial to the midline e Anterolateral leg f Thoracic region just medial to the vertebral column 2 Neuromuscular diseases may lead to a condition called drop foot, in which a patient is unable to dorsiflex his or her foot. Which muscle(s) do you think isla involved in this condition? Which muscles may have to compensate for are lack of dorsiflexion during walking? Explain. 3 One of the most commonly performed orthopedic surgeries is rotator cuff repair, often this involves removing and the deltoid muscle at its insertion. What functional impairment would be present after this procedure? What exercises could a physical therapist use to recondition the deltoid muscle?Explanation / Answer
a) Lateral thigh
Quadriceps and hamstring muscles are the lateral thigh muscles which form the common sites for muscle strain. These muscles are at risk while performing swift actions since they cross the hip and knee joints.
b) Posterior arm
Injury to flexor and extensor muscles can result in pain in posterior arm. Coordinated movement of these muscles help in the movement of arms and wrist.
c) Lateral neck.
Pain in lateral neck may be due the injury of trapezius and levator scapulae. Trapezius is a triangular muscle which attaches to the base of the skull and lies at the back of the neck. They support the weight of the arms. Stress is the major cause of trapezius strain.
Levator Scapulae are located on either sides of the neck and is responsible for movements like shoulder shrugs and arm movements. Injury to these muscles can thus affect other areas of upper body.
d) Abdomen just medial to the midline
A strain in transverse abdominis, internal and external obliques and rectus abdominis can result in pain in abdominal area. Out of this, rectus abdominis is the most superficial. Abdominal strains are common in physically active people like athletes since this group of muscles is constantly engaged in them. Hence, any injury to these muscles will hinder the athlete’s performance.
e) Anterolateral leg
Gastrocnemius, soleus, anterior tibilais and posterior tibialis are the common sites of muscle strain in anterolateral leg region. They are mainly responsible for flexibility and controlling the movement of legs while walking or running.
f) Thoracic region just medial to the vertebral column
A strain to erector spinae may lead to pain in thoracic region just medial to the vertebral column. They are a group of muscles responsible for maintaining good posture. They are usually injured due to repetitive lifting with false posture.
