What do muscles do What do muscles do ??• Muscles simply move you!• Without muscles you couldn't open your

mouth, speak, shake hands, walk, talk, or move your food through your digestive system.

• There would be no exploring, running, climbing, smiling, blinking, breathing. You couldn't move anything inside or outside you. The fact is, without muscles, you wouldn't be alive for very long

The skeleton is the name given to the collection of bones that holds our body up.

Our skeleton is very important to us. It does three major jobs.

1. It protects our vital organs such as the brain, the heart, and the lungs.

2. It gives us the shape that we have. Without our skeleton we would just be a blob of blood and tissue on the floor.

3. It allows us to move. Because our muscles are attached to our bones, when our muscles move, they move the bones, and we move

Physical ExamPhysical Exam

1. Inspection • Observe any lack of symmetry and

any evidence of trauma or disease.• Look for muscle wasting;• Inspect the joint contour (shape)

and observe any evidence of swelling, deformity or inflammation.

• Ask the client to point to, or otherwise identify, any painful areas, including sites of radiation of

pain.

Screening questions for musculoskeletal disorders

1. Do you have any pain or stiffness in your arms, legs or back?

2. Can you walk up and down stairs without difficulty?

3. Can you dress yourself in everyday clothes without any difficulty?

• Assessment of Gait

• Ask the patient to walk back and forth across the room.

• Observe for equality of arm swing , balance and rapidity and ease of turning.

• Next, ask the patient to walk on his tiptoes, then on heels.

• Ask the patient to tandem walk.

• Test patient's ability to stand with feet together with eyes open and then closed. (Romberg's test). Reassure patient that you will support him, in case he becomes unsteady.

• Normal: Person can walk in balance with the arms swinging at sides and can turn smoothly. Person should be able to stand with feet together without falling with eyes open or closed.

Upper Extremity MusclesUpper Extremity Muscles

• Inspect the muscles of the shoulder, arm, forearm and hand.

• Note muscle size (bulk). • Look for asymmetry,

atrophy and fasciculation.

• Look for tremor and other abnormal movement at rest and with arms outstretched.

Determine muscle power Determine muscle power byby

• Gently trying to overpower contraction of each group of muscles. – Shoulder:

Abduction (Deltoid)

– , Adduction– , Shrug

(Trapezius)

– Elbow: flexion (Biceps)

– Elbow extension (Triceps)

– Wrist: Flexion ( )and

extension().

– Hand: Grip

– opposition of thumb and index finger

– opposition of thumb and little finger and

– finger abduction and adduction.

Grip

• Determine limb tone (resistance to passive stretch).

• With the patient relaxed

• Gently move the limb at the shoulder, elbow and wrist joints and note whether tone is normal, increased or decreased

Normal findingsNormal findings

• Muscles are symmetrical in size with no involuntary movements.

• In some, muscles may be slightly larger on the dominant side.

• Muscle power obviously varies. You should not be able to overpower with reasonable resistance.

• You have to learn to appreciate the normal tone from practice.

Neck: Range of Motion ofNeck: Range of Motion of • Fix the head with one hand while you

examine neck • Inspection

– Note the normal concavity of cervical spine

– Identify Transverse process of C7 – Observe Trapezius and Sternomastoid

muscles • Palpation

– Feel each spinous process looking for focal areas of tenderness

– Joint  • Feel for crepitus during passive motion

– Para spinal muscles • Range of motion

– Active • Touch chin for flexion • Throw head back for extension

Touch chin

Throw head back

• Touch each shoulder with ears for lateral flexion

• Touch each shoulder with chin for lateral rotation

– Passive • Feel for crepitus during passive

motion

• Normal: – 30 degree rotation, able to

touch chest with chin, 55 degree extension and 40 degree lateral bend.

– No resistance during the range of motion.

Muscles of Lower ExtremityMuscles of Lower Extremity

Inspect the muscles of the hip, knee and ankle.

• Note muscle size (bulk). • Look for asymmetry, atrophy

and fasciculation. • Look for abnormal movement. • Determine muscle power by

gently trying to overpower contraction of each group of muscles. – Hip: Flexion (Iliopsoas), Extension

(Gluteus maximus), Abduction, Adduction.

Hip flexion

The Knee ExamThe Knee Exam

• Inspection • Make sure that both knees are

fully exposed. The patient should be in either a gown or shorts. Rolled up pant legs do not provide good exposure!

• Watch the patient walk.• Do they limp or appear to be in

pain? • When standing, is there evidence

of bowing (varus) or knock-kneed (valgus) deformity? There is a predilection for degenerative joint disease to affect the medical aspect of the knee, a common cause of bowing.

varus Knee deormity, more

marked on the left leg

• Is there evidence of atrophy of the quadriceps, hamstring, or calf muscle groups? Knee problems/pain can limit the use of the affected leg, leading to wasting of the muscles.

While both legs have well developed musculature, the left calf and hamstring are bulkier than the right

– Knee : Flexion (Hamstrings), Extension (Quadriceps)

– Ankle : Dorsiflexion (Tibialis anterior), Plantar flexion (Gastronemius).

• Determine limb tone resistance to passive stretch. With the patient relaxed, gently move the limb at the hip, knee and ankle and note whether tone is normal, increased or dicreased. Flex the hip and knee.

• Support the knee, dorsiflex the ankle sharply and hold the foot in this position checking for clonus.

Dorsiflexion

Knee extension

Knee flexion

Spine (Bone)Spine (Bone)• The examiner should stand behind the

patient and observe the alignment of the spine in the flexed position to determine scoliosis.

• View the spine from the side to determine kyphosis.

• Ask the patient if he is aware of sore spots. Palpate the spinous process and be gentle with the sore spots. Percuss one vertebra at a time, starting from head.

• .

• Assess range of motion of spine by having patient bend down to pick up an object without bending his legs while you hold his hips.

• Normal: • Gentle concavities in

cervical and lumbar regions and a convexity in the thorax.

• Vertebral line and gluteal cleft align
