    • Muscle Testing of the Upper and Lower Extremities Physiotherapy Division Dr. Mikhled Maayah
    • Guide muscle testing• This guide was developed out of a need to assist the therapist in utilizing a standard method of muscle testing in patients at this facility.• It is based on the denials and Worthingham method of muscle testing.• It was originally developed approximately a long time ago as a procedure to assist physiotherapy students who working with the physically disabled.• Since that time it has been utilized by staff, who have given suggestions over a period of years to make it more meaningful and useful to gain proficiency and consistency in muscle testing.
    • Introduction• The general direction of treatment today is to consider the whole patient in terms of what we do to help him gain maximum recovery and independence.• To accomplish this we must think of him in terms of his status at the beginning of treatment, the prognosis, the plan of treatment and the progress noted under this plan.• It should be a matter of professional pride that we be able to provide accurate and meaningful information, when it is requested of us.
    • Introduction- continueAs therapists, we consider muscle evaluations from two points of view:• For our use own as guides to planning of specific treatment routines and to determine the success or failure of these routines.• To provide the physicians with whom we work with information which will be helpful to them in: – diagnosis – prescription for treatment – prescription for bracing – determination of progress and prognosis.
    • Introduction- continue• There are certain specific things which we want to knew. These are: – Is the muscle active? – Is the muscle functional? – How functional is it? – Is spasticity present? – What substitute patterns are present? – What positions the patients assumes at rest? – What positions the patients assumes on activity? – What deformities are present and to what degree? – What stage of motor development has been reached? – What are the specific motor handicaps which keep him developing more rapidly or becoming more independent?
    • Introduction- continue• In addition, the therapist must be able to convey to the patient what is expected of him in a testing procedure and then be able to record the results of the test in concise way.• Testing by a well trained therapist saves time for the physician and can be great help to him.• Objective testing done at stated intervals serves not only to record progress, or lack of it, but gives us an excellent opportunity to evaluate the technique used.• It also gives information needed to report intelligently to the physician on the status of the patient.
    • Definition of muscle testA muscle test is an attempt to determine the abilityof a patient to activate skeletal muscle.Available range of motion: this is the passive rangewhich is easily obtained by the examiner withoutfeeling resistance.Example: If passive range measured in elbow flexionis 0 – 90 degree and patient actively moves 0 – 90degree, then he will have moved through completeavailable range of motion.
    • Muscle test is used as:-• Basis of muscle re-education and exercise.• Determining factor for supportive apparatus.• Aid in determining diagnosis.• Aid in prognosis of a patient.
    • Requisites for good muscle testing– Knowledge of anatomy as well as functional.– Correct starting position-changes with muscle being tested.– Stabilization of proximal segment and body as a whole.– Area of palpation-knowledge of where and how to palpate.– knowledge of the substitutions muscles (synergic muscles, assisting muscles, direct fixation muscles, indirect fixation muscles and antagonistic muscles).– Recognition of substitution.– Knowledge of normal muscle and muscle groups (action and appearances).– Ability to convey ideas to patient and guide the movement.– Record deformities, limitations in motion, spasticity and tremor, strength within range must be recorded (grade low when in doubt about strength of a muscle).
    • Terminology• Test Range: is set up for specific test of specify muscle – not necessarily complete ROM.• Easy Test: gravity eliminated test or position that will give you a grade of 0, Trace, Poor -, Poor.• Hard Test: anti-gravity (against), method used to obtain grades from Fair+ to normal.• Palpation: ability of therapist to feel contraction of muscle being tested.• Resistance: applied at the end of ROM, pressure should be applied in a direction as nearly opposite to the line of pull of the muscle or group, as possible.
    • Muscle grading techniques• Grades are obtained on varies of gravity, gravity eliminated, against gravity, gravity plus manual resistance.• Some grades are obtained by palpation.• Stretch range used for some grades – range beyond neutral position, usually used in rotation.
    • Grades• The following muscle grades are described in comparison with a normal muscle.• It is important to keep in mind that muscles of normal strength vary in strength tremendously within the body., owing to the size of the muscle and to the work each muscle is normally required to perform.• Normal strength likewise varies between individuals, owing to differences in age and body requirements.• Therefore, in grading muscles above ‘fair’, the degree of objectivity increases with the therapist’s increasing knowledge of normal strength of various age groups and body requirements for that particular muscle, prior to illness or injury.
    • Grades• Zero (O): No movement of part; contraction cannot be palpated• Trace (T): Contraction can be palpated; no movement of part.• Poor minus (P-): Gravity eliminated, part moves through only a portion of the range of available, not necessarily normal, passive ROM.• Poor (P): Gravity eliminated, part moves through complete available ROM.• Fair: Against gravity, part moves through complete available ROM, but cannot take additional resistance.• Fair Plus (F+): Part moves through complete available ROM against gravity with ‘slight’ resistance (for that muscle) at end of range.• Good (G): Part moves through complete available ROM against gravity and takes “moderately strong” resistance (for that muscle) at end of range.• Normal (N): Part moves through complete available ROM against gravity and takes “strong” resistance (for that muscle) at the end of range.
    • Recording• All grades below fair are recorded in red for easily identifiable areas of weakness; grades of fair and above are recorded in blue or black ink and dated.• Indicate all muscles not tested during any evaluation by marking “N.T” in the appropriate place.
    • Outline of technique for administering the manual muscle test• Determine the ROM of joint (joints) passively.• Line up the part with fibers of the muscle to be tested.• Provide adequate stabilization.• Have the patient attempt motion through the test range.• Look at the muscle or movement first.• Palpate at the tendon or muscle belly.• Apply resistance at the end of the range if the muscle is strong enough (Break Test).
    • Outline of technique for administering the manual muscle test• Resistance should be applied firmly and smoothly in line with direction of the muscle of segment of a muscle being tested.• You may compare the strength of the normal segment with the one being tested to aid in determine the strength grade.• Never give a grade on motion alone. It must possible to palpate the muscle.• Record grade and date and initial the test form.• Normal in relation to muscle testing: normal for are, sex and sounded parts.
    • Some basic principles1. Take your time.2. Start with a gross observation of function around a joint.3. Patient instruction.4. Be consistent.5. Grading.6. Check yourself.7. Suggested sequence of extremities muscle test.
    • Some basic principles1. Take your time: – Don’t rush to a conclusion about a grade. – Use plus or minus if patient’s performance is consistent with stated definitions of grades. – If patient’s performance is not consistent with stated definitions, use descriptive terminology, e.g. biceps remains F+ but is taking more resistance than last test.
    • 2. Start with a gross observation of function around a joint: – Observe the ROM around the joint as it is often a clue to muscle imbalance. – Then observe gross movement around the joint before touching with hands. – Observe muscle atrophy. – Observe and check muscle tone. – The presence of spasticity may negate the value and appropriateness of performing a manual muscle test. – Be aware of sensory deficits as they may affect patient’s ability to follow directions.
    • 3. Patient instruction: – It is important to give patients all sensory and verbal clues needed for best performance. – This may include: • Demonstrations • Taking part through motion desired • Allowing patient to see part being tested • Allowing practice through muscle re-education techniques (when appropriate) • Using simple instructions.
    • 4. Be consistent: – Begin by testing the muscle against-gravity, then test in a gravity-eliminated position if muscle is below “Fair”. – Always apply resistance at the end of the motion rather than during the motion. – Resistance is usually applied at the distal end of the part and opposite to the direction of pull.
    • 5. Grading: – When utilizing the grading system above, examiner must observe proper testing position of the patient for the muscle being tested. – When it is not possible to assume proper testing position, e.g. due to contractures, casts, medical precautions, it is important to determine presence or absence of muscle in question. – In this case, the degree of contraction can be determined as weak or strong, utilizing palpation and observable active motion. – Because some body parts cannot be positioned to work against gravity, the grading of some muscles is modified, as indicated in the procedure to follow. – Recognize that larger muscles would take maximum effort by tester to resist a strong muscle and proportionally less effort for smaller muscles.
    • The gravity factor in Grading• For other muscles, the gravity free and ant-gravity positions are impractical because gravity may not be an important factor (Finger flexors, toe flexors, forearm pronators and supinators, rotators of the shoulders and hips).• From a mechanical stand-point this is true because the weight of the part is so small in comparison with strength of the muscle.• Foot, hand or their range of motion is much that if the initial position is anti-gravity, the end position is with gravity.• Supinators and pronators could be scored:• Tr : perception of attempted assistance in stretch range
    • 6. Check yourself on the following factors: – What is the primary action of the muscle being tested? – Is the patient in the proper test position? For example, if patient’s biceps is less than F in a sitting position, have I repositioned for gravity eliminated grading? – Have I stabilized the part proximal to the part on which the muscle acts?
    • – Have I observed to see that the motion produced is the motion requested, e.g. is there extraneous motion at joints proximal and/or distal to the part being tested?– Have I palpated after observing the motion?– Have I applied resistance in the proper place at the end of motion?– Have I graded, using the proper definition of grades.
    • 7. Suggested sequence of extremities muscle test• The following suggested sequence first provided to enable the tester to efficiently perform all the tests with the least amount of re-positioning of the patient.• Note that all muscles which can be tested for both above and below F are grouped together.
    • Suggested sequence of upper extremity muscle testA. UPRIGHT: – Elbow, Forearm, wrist and Hand. – Serratus anterior and pectoral is major (clavicular). – Anterior deltoid – Middle deltoid – Upper trapezius – Latissimus dorsi F+ and above
    • B. PRONE:• Triceps• External rotators• Internal rotators• Posterior deltoid• Rhomboids• Middle trapezius• Lower trapezius• Latissimus F- and below.
    • C. Sideling: with weight of arm supported on a smooth board. – Anterior deltoidD. SUPINE – Pectoralis major (sternal) – Triceps (alternate position) support weight. – Elbow flexors (alternate position of arm on smooth Middle deltoid).E. Upright (below Fair): Posterior deltoid Pectoral is major (sternal). External rotators Internal rotators
    • Suggested sequence of lower extremity muscle test• Turning the patient from one position into another is fatiguing to the patient and wasting for the therapist’s time.• Supine: Toe flexors and extensors, tibialis posterior and anterior, peroneals and triceps.• Side lying: Gluteus medius and minimums adductors, lateral abdominals and tensor fascia lata.• Prone: Hamstrings, gluteus maximums.• Sitting: Quadriceps, internal and external rotators of the hip, iliopsoas, sartorious

    • Shoulder Goniometry
    • Introduction1. It is the measuring of angles created by the bones of the body at the joints.2. These joints are measured by a goniometer.3. It has a moving arm, stationary arm, and the fulcrum.4. The fulcrum or body is placed over the joint being measured and on it is a scale from 0 to 180°.5. The stationary arm will be aligned with the inactive part of the joint measured, while the moving arm is placed on the part of the limb which is moved in the joint’s motion.6. For example, when measuring knee flexion, the stationary arm will be aligned over the thigh in line with the greater trochanter of the femur.
    • Introduction - continue7. The fulcrum is aligned over the knee joint or lateral epicondyle of the femur, and the moving arm with the midline of the leg or lateral malleolus.8. Performing these tests is important for many reasons. • The mobility of joints is important for diagnosis and determining the presence or absence of dysfunction.9. In a chronic condition, goniometry can measure the progression of the disorder. • An example of this is the progression of rheumatoid arthritis.10. Furthermore, joint motion measurement can evaluate improvements or lack of progression during rehabilitation.11. This not only provides motivation for the patient when there are improvements, but also can decipher if modifications need to be made if treatment is not effective.
    • FlexionPatient Instructions:• Once the goniometer is aligned properly ask the patient to lift the arm up just as if they were raising their hand to ask a question.• Be sure that the patient keeps the palm of their hand facing in toward their body.
    • Starting Position • Patient is supine with arm at side and the palm of the hand facing the body. • The fulcrum of the goniometer is placed over the acromion process. • The stationary and moving arms are aligned with the midline of the humerus and lateral epicondyle.
    • Ending Position • The moving arm remains in line with the lateral epicondyle and midline of the humerus. • The examiner supporting the patient’s extremity. • The stationary arm should remain in its starting position, only now it should be in line with the lateral midline of the thorax. • Normal ROM for glenohumeral flexion is 160 to 180º; in the picture the patient is in 180º of flexion.
    • Extension• Patient Instructions:• Ask the patient to simply lift their arm off the table as far as they can.
    • Starting Position • Patient is prone with arm at side; make sure the head is facing away from the shoulder being tested. • Elbow bent slightly and the palm facing in toward the body. • The fulcrum is placed over the acromion process. • The stationary and moving arms are aligned with the lateral midline of the humerus and the lateral epicondyle.
    • Ending Position • The moving arm remains in line with the lateral epicondyle and the examiner should support the patient’s extremity. • The stationary arm in line with the midline of the thorax. • Normal ROM for glenohumeral extension is 40 to 60º; in the picture the patient is in 61º of extension.

The anterior bundle is the most important functionally, since it provides valgus and anteroposterior stability. Figure 6 Diagrammatic view of the lateral ligament complex. It would appear that the most import structure is the lateral collateral ligament, which blends with the annular ligament. The lateral ulnar collateral ligament is indissociable from the lateral collateral ligament, at its attachment to the lateral epicondyle. Distally, it branches off, and attaches to the supinator crest. The role of the accessory lateral collateral ligament is poorly understood.

    • CLINICAL EXAMINATION
    • INSPECTION• The patient should be standing, with shoulders slightly braced back, to display the elbow.• When the forearm is in full extension and supination, there will be a physiological valgus ("carrying angle") of 9-14°; in women, the angle will be 2-3° greater• This angle has been found to be 10-15° greater in the dominant arm of throwing athletes• This angle allows the elbow to be tucked into the waist depression above the iliac crest; it increases when a heavy object is being lifted• Any increase in, or loss of, this physiological angle is indicative either of major elbow instability or of malunion.• However, the angle varies from valgus in extension to varus in flexion, and its measurement is not of any practical importance.
    • Inspection• Sometimes, on the side of the elbow, bulging in the para-olecranon groove will be seen; such a swelling is produced by an effusion or by synovial tissue proliferation• On the back, prominence of the olecranon is a sign of posterior subluxation of the elbow, a feature commonly found in RA .• Rheumatoid nodules are extremely common• Bursitis is also a frequently encountered pathology, especially in RA patients.• Skin atrophy at steroid injection sites, or scars from previous surgery.
    • Figure 8The physiological valgus (“carrying angle”) of theelbow is increased when a load is being carried.Normally, the angle is between 9 and 14° when theelbow is extended and the forearm is supinated.
    • PALPATION• Palpation starts at the posterior aspect, with the patient standing with his or her shoulder braced backwards.• The three palpation landmarks - the two epicondyles and the apex of the olecranon - form an equilateral triangle when the elbow is flexed 90°, and a straight line when the elbow is in extension (Figs. 9, 10).
    • PALPATIONFigures 9, 10Three bony landmarks - the medial epicondyle, the lateralepicondyle, and the apex of the olecranon - form anequilateral triangle when the elbow is flexed 90°, and astraight line when the elbow is in extension
    • PALPATION• Since the elbow is a very superficial joint, it can be readily palpated from behind and from the sides.• The posterior aspect has the olecranon mid-way between the medial and the lateral condyle.• Slight elbow flexion will bring the olecranon out of the olecranon fossa, in which it lodges in extension; in this position, the proximal portion of the fossa on either side of the triceps tendon may be palpated (Fig. 11)
    • PALPATION • Figure 11 Flexing the elbow allows palpation of the olecranon fossa on either side of the triceps tendon. • Figure 12 Anatomical landmarks on the lateral aspect of the elbow: The lateral epicondyle continues proximally in the supracondylar ridge. • Two 2cms distally, the main landmark is formed by the radial head.
    • • The olecranon bursa is not in communication with the synovial cavity.• This is why the elbow may be mobilized in bursitis, and why even massive bursitis will not be tender.• In chronic bursitis, a boggy globular mass may be palpated; the overlying skin will be thickened. Flat, hard nodules may be felt under the palpating fingertips.• In infected bursitis, the skin will be tight and shiny; streaks of lymphangitis will be commonly seen; while in 25% of the cases, the axillary lymph nodes will be enlarged.• On the lateral side, the main landmarks are the lateral epicondyle proximally and the radial head distally.
    • • The supracondylar ridge is also very accessible to palpation; its chief value is that of a landmark for surgical approaches (Fig. 12).• Sometimes, palpation may be carried out all the way up to the deltoid tuberosity.• The radial head is palpated with the examiner’s thumb, while the other hand is used to pronate and supinate the forearm (Fig. 13).• The head is about 2 cm distal to the lateral epicondyle• Inside the triangle formed by the bony prominences of the lateral epicondyle, the radial head and the olecranon, the joint itself is palpated, to detect even very minor effusions or low-grade synovitis (Fig. 14(
    • Figure 13• Anatomical landmarks on the lateral aspect of the elbow:• The radial head is palpated with the thumb, while the examiner’s other hand is used to pronate and supinate the forearm PALPATION.Figure 14• The elbow joint may be palpated inside a triangle formed by the bony prominences of the lateral epicondyle, the radial head, and the olecranon.• This palpation will reveal even minor effusions or mild synovitis.• Puncture for joint aspiration is performed inside this triangle.• Similarly, an arthroscopy portal may be placed there (posterolateral portal(
    • • Figure 15 Palpation and testing of brachioradialis, a forearm flexor. • Figure 16 Palpation and testing of the wrist extensorsPALPATION
    • PALPATION• From the medial side, the joint is not very accessible to palpation, and the small amount of synovial tissue on the medial border of the olecranon makes joint palpation difficult• Palpation of the ridge that provides insertion for the intermuscular septum is useful mainly as a guide for surgical approaches. Also, the supracondylar lymph nodes may be palpated at this site (Fig. 17).• Over, and slightly anterior to, the supracondylar ridge, a bony excrescence may be palpated; this outgrowth may irritate the median nerve• This supracondylar process is present in 1-3% of the population, and is seen at a distance of 5-7 cm above the joint line• Behind the septum, the ulnar nerve may be palpated; in patients with a very mobile nerve, it may be seen to roll on the medial condyle(10) (Fig. 18).• Ulnar nerve instability is more easily tested with the arm in slight abduction and external rotation, with the elbow flexed between 20 and 70°.
    • Figure 17• Palpation of the medial aspect of the elbow.• Above the medial epicondyle is the ridge on which the intermuscular septum inserts.• Two centimetres above the epicondyle is the site used for lymph node palpation.Figure 18 The ulnar nerve is palpatedbehind the intermuscularseptum.It may sometimes sublux or rollon the epicondyle.Ulnar nerve instability is morereadily demonstrated if theelbow is flexed 60° and theupper limb is abducted andexternally rotated.
    • PALPATION• Anteriorly, the bulk of the flexor-pronator group restricts the extent of joint palpation.• The flexor-pronator muscles must be tested as a unit, by asking the patient to perform wrist adduction and flexion against resistance (Fig. 19).• Next, each one of these muscles should be tested individually.• The anterior aspect does not lend itself to palpation, since it is tucked away behind the muscles.• Laterally, brachioradialis will be felt; and in the middle, the biceps tendon is readily accessible if the patient is made to flex the forearm against resistance.• Lacertus fibrosus is palpated medial to the biceps tendon; the pulse of the brachial artery will be felt deep to this aponeurosis (Fig. 20).• Sometimes anterior protrusion cysts produced by herniated synovial membrane may be felt.

    • MOBILITY• The main function of the elbow is to bring the hand to the mouth; this is why the investigation of the elbow range of movement (ROM) is an important part of the examination process.• Any difference between passive and active mobility is usually due to reflex inhibition from pain• The end-feel - the feeling transmitted to the examiner’s hands at the extreme range of passive motion - must also be assessed (Table 1)• If the feel is abnormal, there is usually something wrong with the joint.

    • ELBOW JOINT• The elbow is a complex joint with three different articulations.• The humeroulnar joint is a hinge joint, and allows the forearm to flex and extend, and provides stability.• The radiohumeral and radioulnar joints allow for flexion, extension and rotation of the radius on the ulna, which in turn allows the forearm to pronate and supinate.

    • Rheumatoid arthritis trigger
    • Trigger Finger• Definition• Trigger finger is an inflammation of the synovial sheath that encloses the flexor tendons of the thumb and fingers. Tendons are the cords that connect bones to muscles in the body. Usually, tendons slide easily through the sheath as the finger moves.• In the case of trigger finger, however, the synovial sheath becomes swollen and the tendon cannot move easily through small pulleys in the finger, causing the finger to remain in a flexed (bent) position.• In mild cases, the finger may be straightened with a pop, like a trigger being released.• In severe cases, the finger becomes stuck in the bent position.• Usually this condition can easily be treated; contact your doctor if you think you may have trigger finger.
    • Causes• Often, the cause of trigger finger is unknown. However, many cases of trigger finger are caused by one of the following:• Overuse of the hand from repetitive motions – Computer operation – Machine operation – Repeated use of hand tools – Playing musical instruments• Inflammation caused by a disease – Rheumatoid arthritis – Gout – Hypothyroidism
    • Risk Factors• The following factors increase your chances of developing trigger finger:• Age: 40-60• History of repetitive hand motions for work or play• Sex: female• History of certain diseases: – Rheumatoid arthritis – Gout – Hypothyroidism
    • Symptoms• If you experience any of these symptoms do not assume it is due to trigger finger. Some of these symptoms may be caused by other health conditions. If you experience any one of them for a period of time, see your physician. – Finger or thumb stiffness – Finger, thumb, or hand pain – Swelling or a lump in the palm – Catching or popping when straightening the finger or thumb – Finger or thumb stuck in bent position
    • Diagnosis• Your doctor will ask about your symptoms and medical history, and perform a physical exam. The physical exam may include:• Asking you to move the affected finger or thumb• Feeling the hand and fingers• For severe cases of trigger finger, your doctor may refer you to a hand specialist.
    • Treatment• The goals of treatment for tenosynovitis are: –to reduce swelling and pain –to allow the tendon to move freely with the tendon sheath.
    • • Treatment options include the following:• Rest• Stopping movement in the finger or thumb, sometimes with the help of a brace or splint, is often the best treatment for mild cases of trigger finger.• Rest may be combined with stretching of the muscle tendon unit involved.
    • • Medications• Several medications are used to treat tenosynovitis. These include:• Corticosteroids, given as an injection into the synovial tendon sheath to reduce swelling of the tendon sheath• Nonsteroidal anti-inflammatory drugs (NSAIDs) to help reduce inflammation and pain: – Ibuprofen (Advil, Motrin) – Naproxen (Aleve, Naprosyn)• For severe cases of trigger finger that do not respond to medications, surgery may be used to release the finger from a locked position and to allow the tendon to move freely through the sheath.• This surgery is usually performed on an outpatient basis and requires only a small incision in the palm of the hand.
    • Prevention• The most important action you can take to prevent trigger finger is to avoid overuse of your thumb and fingers.• If you have a job or hobby that involves repetitive motions of the hand, you can take the following steps: – Adjust your workspace to minimize the strain on your joints – Alternate activities when possible – Take breaks throughout the day – Exercise regularly
