 Fatigue is defined as the subjective complain of
tiredness or diminished energy level to the point
of interfering with normal or usual activities.
 Fatigue can be menifested as difficulty or
inability initiating activity ( perception of
generalized weakness) reduced capacity
maintaining activity and difficulty with
concentration , memory and emotional stability.

history
Physical examination
Laboratory studies
 ID : Age, Gender, Nationality, Occupation
 Chief complain
 Onset : abrupt or gradual, related to event or
illness
 Course : stable, improving or worsening?
 Factors that alleviate or exacerbate symptoms
 Impact on daily life- ability to work
Medical
history
Family
history

history
Social
history
Allergy
history
 When the fatigue is started, how long it lasts,
and what makes it better or worse?
 Symptoms or side effects, such as pain, the
patient having from the cancer or the
treatments.
 Medicines being taken.
 Sleeping and resting habits.
 Eating habits and changes in appetite or
weight.
 Whether the patient has depression, anxiety
 Health habits and past illnesses and
treatments.
 How the fatigue affects being able to work.
 General appearance
 Posture
 patient’s walking
 Trouble breathing or loss of muscle strength
 Palpation
 Analogue scale: describes the fatigue on a
scale 1 to 10
1 5 10
 Anemia: pallor, tachycardia, systolic ejection
murmur
 Goitre or thyroid nodule: dry skin, delayed
deep tendon reflexes, peri orbital puffiness,
 Hyperthyroidism: weight loss, hyper reflexia,
fine tremor, atrial fibrillation.
 Addison’s disease: hypotension, scar,
pigmentation in skin creases
 Heart failure: elevated jugular venous
pressure, ankle edema
Systemic

assessment
Anaerobic fatigue:
 Assessment of the fatigue during anaerobic
power performance when vigorous exercises
continues for more than few seconds .
 Anaerobic fatigue is the percentage decline in
the power output during the test.
 The various tests which are used for
anaerobic fatigue are following:
Katch test
Wingate cycle
ergometer test
Measurement of
blood lactate level
 Procedure
 Test scores:
• Peak power output = force * distance
(num of revolutions*distance per revolution
divided by time in minutes)(5secs=o.o83min)
• Anaerobic fatigue=high power output – low power
output divided by high power output* 100
 if a man weighing 73.3 kg performs wingate test
on a Monark cycle ergometer (6.0 m traveled per
pedal revolution) with an applied resistance of
5.5kg (73.3*0.075=5.49 rounded off to 5.5kg),
pedal revolution at 5 secs interval is 12,10,8,7,6,5
(48 total revolution in 30 seconds)
 Peak power output= force*distance divided by time
5.5kg*(12*6)divided by 0.083 min
4753kg.m/min or 776.8 watts
 Anaerobic fatigue=high power output-low power output
divided by high power output * 100
High power output is 776.8 W
Low power output= force*distance divided
by time
5.5 * (5*6) divided by 0.083
1980.8 kg.m/min = 323.7 W
Anaerobic fatigue = 776.8-323.7 divided by 776.8*100=58.3%
 Fatigue is reached the amount of lactate in
the muscle and blood is maximum.
 Measurement of lactate in blood can give an
idea regarding the extent of fatigue.
Measurement of aerobic capacity
• vo2 max = co * arteriovenous o2 diffrence
• Arteriovenous o2=arterial o2- venous o2
Measurement of energy expanditure
• Spirometry testing
 Assessment procedure which indicate a fall in
the strength or firing ability of the muscle
fiber can be used to determine fatigue.
Decremental
studies
EMG
MMT
 Brief fatigue inventory
 Fatigue severity scale
 Piper fatigue inventory
 Depending on the findings in the history and
physical examination, blood tests and other
imagine studies may be ordered.
 CBC (complete blood count)
 Blood sugar
 TSH
 Tests for deficiency in vitamin B12, D,folic
