-flexion and extension (sagittal plane), radial deviation and ulnar deviation (frontal plane) occur at the radiocarpal joint (with some accessory motion at the carpal bones)
-flexion occurs as the palm is brought toward the anterior surface of the forearm: 80°
-extension occurs as the back of the hand is brought toward the posterior surface of the forearm: 70°
(hyperextension)
-radial deviation (abduction) occurs when the radial side of the hand is moved in a laterally: 20°
-ulnar deviation (adduction) occurs when the ulnar side of the hand is moved in a medially: 30°
- Thumb:
-movements occurs at the carpometacarpal (CMC), metacarpophalangeal (MCP) and interphalangeal
(IP) joints

- Extension occurs as the finger is brought back to anatomical position
-hyperextension occurs as the finger is brought past full extension: 30° (more passive motion)
-flexion (PIP & DIP) occurs as tip of finger is brought toward anterior surface of palm: 100° (PIP); 85-90-
(DIP)
-extension occurs as finger held in anatomical position
-abduction and adduction (MCP) occurs in the frontal plane
-abduction is movement away from the midline of the hand versus midline of body
-adduction is return to anatomical position
Capsular Patterns
Elbow: flexion more limited than extension
Forearm Radioulnar joints: pronation and supination usually equally limited
Wrist: flexion and extension equally limited; possible slight limitation in radial and ulnar deviation
Thumb CMC joint: abduction most limited; extension limited after abduction
Thumb MCP & IP joints: flexion more limited than extension
Fingers MCP, PIP & DIP joints: flexion limited most, followed by extension
Range of Motion
AROM: demonstrate the movement to be performed; have patient perform the movement
-pain indicates problems in either the contractile or inert tissues
-factors prematurely limiting active movement include ligamentous or capsular damage, muscle contractures, pain from nerve compression or tension, tendinosis, tenosynovitis, fibrous cysts or joint disorders (arthritis)
PROM: establish the joint’s normal end feel, have patient relax as much as possible, use gentle and slow movements
-predominantly implicates inert tissues; muscles and tendons that contract in the opposite direction are stretched at end range
Resistive Tests
MRT: test one action at a time, position should isolate the action/muscles involved; if pain is suspected, start in a mid-range position; patient using a strong, but appropriate amount of effort
-pain indicates that one or more of the muscles and/or tendons performing that action are involved
-may be weakness due to lack of use, fatigue, reflex muscular inhibition and possibly, a neurological pathology

- Excessive Cubital Valgus
Structural and Postural Deviations
Characteristics: in anatomical position there is a natural angulation of the forearm (cubital valgus/carrying angle) which allows the forearm to swing away from the body during normal walking stride
-valgus angulation: lateral deviation of the distal end of a bony segment; approx. 5-15°
-excessive carrying angle is greater than 15°
-no specific symptoms but can lead to cubital tunnel syndrome, medial epicondylitis, apophysitis and myofascial trigger points
-usually results from genetics, can be caused by injury (fracture); injury can also cause cubital varus or gunstock deformity
History: ask about pain/symptoms; ask about injuries/fractures; ask whether aware of deviation; identify nature of injury and damage to adjacent structures
Observation: see when patient is standing in anatomical position; compare angulations of both sides; measure with goniometer
Palpation: no significant findings; irritation of ulnar nerve or attachment sites of flexor muscles may cause tenderness; injury may produce residual tenderness
Range of Motion and Resistance Testing
AROM: not impaired unless results from traumatic injury; pain or irritation may develop near end of full flexion as ulnar nerve and flexor tendons stretched
PROM: as with AROM MRT: no unusual findings
Suggestions for Treatment: no treatment unless soft-tissue disorders occur; if nerve impairment or recurrent nerve pain, refer to physician
- Dupuytren’s Contracture
Structural and Postural Deviations
Characteristics: fibrosis of the palmar fascia that affects the tendons of the fingers (flexion contractures) that force fingers to curl into flexion at MCP, PIP or DIP joints; usually affects both hands but can have different degrees of severity
Proliferative phase: myofibroblasts develop
Involutional phase: myofibroblasts align along tension lines
Residual phase: tissue becomes acellular and leaves thick bands of collagen
-begins with loss of ROM in fingers and progresses as the flexion contractures develop leading to loss of finger extension
-fingers are held in constant, but varied, degree of flexion; pronounced in 4th and 5th digits
-causes not well understood
-factors that increase risk: diabetes, seizure disorders, smoking, drinking alcohol excessively
-may have a genetic predisposition; more likely in men
History: thickening sensations just under skin on palm, pain or tightness and loss of motion in fingers; depends on developmental stage; ask about physician involvement; identify history of seizures or diabetes; ask about smoking/drinking; ask about familial history
Observation: thickening of palmar fascia; fibrosis gathers around flexor tendons which look cord-like; pitting and loss of mobility in the skin of the palm evident during some hand movements
Palpation: fibrous nodules may be present in palm or joints of fingers; can develop into cord-like structures; skin feels firm or tight
Range of Motion and Resistance Testing:
AROM: flexion and extension impaired
PROM: crepitus or stiffness; flexion can be limited; extension limited due to contractures MRT: weakness with flexion and extension; reduced grip strength, flexion may cause pain
Differential Evaluation: stenosing tenosynovitis, nerve compression, pathologies, rheumatoid arthritis, synovial ganglions, tumours or fibrositic processes in the hand
Suggestions for Treatment: splinting, ultrasound, stretching, flexibility exercises, injection therapy; surgery; stripping and myofascial techniques help to reduce fibrosis and increase ROM
- Rheumatoid Arthritis
Structural and Postural Deviations
-a systemic autoimmune disorder that is polyarticular; hands and feet affected most frequently; may affect other tissue other than joints with advanced stages; viruses, bacteria or fungi are involved and may be the cause; may be genetic or environmental factors; rheumatoid factor is usually present
Characteristics: immune system erroneously attacks the lining of the synovial membrane surrounding the joints through an enzymatic reaction that causes articular degeneration
-progressive
-initially, inflammation and proliferation of fibrous tissue causes swelling, heat, puffiness and fibrin deposits that cause movement pain; ROM decreased due to stiffness and pain; sores in the morning due to accumulation of fluid in synovial tissues; fever, fatigue and anemia may be present
-symptoms are intermittent because the disease can flare up and then go into remission
-during flare-up, the joints become stiff and sore bilaterally
-degree of swelling and deformity in the hands distinguishes it from osteoarthritis
-can produce stenosing tenosynovitis (trigger finger) due to inflammation in the synovial sheaths of flexor tendons
-as it progresses, continued thickening of synovial membranes which can lead to tendon adhesions and ruptures, loosening of joint capsules, subluxations and permanent deformities
-temporary/permanent deformities at MCP joints; held flexed or laterally/medially (ulnar drift)
-can also deviate in swan-neck (PIP extension, DIP flexion) and boutonniere (DIP flexion, PIP extension)
deformities
-occurs in older individuals, women more than men; oral contraceptives and pregnancy decrease risk; smoking, obesity, blood transfusions increase risk
History: swelling and pain in various joints (hands and feet); bilateral pain more often; pain at rest, magnified by movement; joint stiffness and limited ROM pronounced in the morning; deformities in hands; fatigue and periodic fever may be reported
Observation: enlarged joints with visible nodules, skin may be puffy, red or shiny during initial inflammatory reaction; look for ulnar drift, swan-neck or boutonniere deformity
Palpation: heat, swelling or nodules, painful with palpation; stiffness due to fibrosity
Range of Motion and Resistance Testing:
AROM: any motion may be painful; not painful if not flared-up; limited motion due to pain and/or fibrosity
PROM: as with AROM
MRT: weakness due to neurological inhibition and fibrositic changes in muscle-tendon unit; may produce pain if engage muscles acting on affected joints
Differential Evaluation: stenosing tenosynovitis, Dupuytren’s contracture, osteoarthritis, degenerative joint disease, gout, peripheral nerve compression, tendinosis, tenosynovitis
Suggestions for Treatment: refer to and receive clearance from physician; palliative care; relaxing massage; massage contraindicated in acute stages; primary goals are to manage symptoms, prevent further inflammation and reduce risk of permanent joint damage
Lateral Epicondylitis ( Tennis elbow) ( extensor carpi radialis)
Common Injury Conditions
Characteristics: chronic collagen degeneration in the extensor tendons and enthesopathy (irritation of the attachment site) at the lateral epicondyle of the humerus
-repeated tensile stress on tendons leads to collagen degeneration and enthesopathy
-extensor carpi radialis brevis (ECRB) is most affected; all other wrist extensor muscles may be involved
-pain aggravated by actions that engage extensor muscles in a contraction (concentric, isometric or eccentric)
-wrist flexion produce pain due to extensor tendons being stretched
→ uncomfortable
-in acute cases, pain results from fibre tearing in tendon or periosteal tears at ECRB tendon attachment
-sports, occupations or hobbies that require repetitive grasping; also repetitive supination or pronation
-uni or bilateral
-other conditions can co-exist: myofascial trigger points can cause extensor muscles to be hypertonic, create an excess tensile load on tendons
History: pain in lateral elbow region, radiates into forearm; aching or sharp pain; ask about gradual or sudden; ask about activities requiring repetitive gripping or static contractions of forearms or wrist; may have difficulty grasping or lifting a smaller item
Observation: hot inflammatory ( n: may be a bit, but must not → no heat); unless perfostealtear or enthesitis (but not visible)
Palpation: tenderness and pain at extensor tendon attachment at lateral epicondyle; wrist extensors feel hypertonic; pain increased if wrist put in flexion and muscles/tendons palpated; fibrotic or ropy feel; may be referrals from trigger points near elbow or forearm when forearm muscles palpated; entrapped posterior interosseous nerve could produce pain down forearm
Range of Motion and Resistance Testing:
AROM: pain may or may not be present with wrist extension; pain at end range of flexion as extensors stretched
PROM: pain at end range of flexion as tendons stretched
MRT: pain with wrist extension; weakness due to reflex muscular inhibition; weakness can also be from compression of posterior interosseous nerve compression
Special Tests:
(N: MRT+ press)
Tennis Elbow Test; standing or seated; therapist wraps one hand around patient’s elbow so thumb is pressing on extensor tendons distal to lateral epicondyle of humerus; therapist’s other hand grasps patient’s hand and uses it to resist patient’s wrist extension; offer resistance only, do not push; contracting wrist extensors causes pain as affected tendons pulled near attachment site; pressing on tendons while in contraction, stress to damaged tissues is exaggerated
Differential Evaluation: radial tunnel syndrome, myofascial trigger point activity, ligament damage near elbow, radial neuropathy, cervical radiculopathy, joint pathology of elbow, medial epicondylitis
Suggestions for Treatment: treated conservatively; ultrasound, stretching, ROM exercises and electrical stimulation; anti-inflammation medications during early stages; deep friction applied directly to affected tendons to stimulate collagen production in damaged fibers; deep longitudinal stripping, myofascial approaches and active engagement beneficial to restore optimum function
Medial Epicondylitis ( Golfer’s elbow)
Common injury conditions
Characteristics: affect wrist flexors where they attach to the medial epicondyle of the humerus; not inflammatory; excessive tensile stress on the flexor tendons causes chronic collagen degeneration (tendinosis) and enthesopathy at the attachment site
-repetitive or prolonged contractions of the wrist flexors
-often due to manipulation of tools and equipment with the hands or throwing actions
-may derive from repetitive supination and pronation of forearm (stresses pronator teres); proximity of its attachment at medial epicondyle cause it to be involved
-concentric, isometric or eccentric contractions aggravate pain
-pain may also occur in motions requiring wrist extensions where flexor tendons are stretched
-pain during activity, subsides after activity ceased ..
-poor conditioning is another cause
-may result from injury leading to chronic tendon irritation; may be some initial inflammation with minor tendon fibre tearing
-other conditions seen along with ME are carpal tunnel syndrome, ulnar nerve pathology
History: pain on medial side of elbow, radiates into forearm, general aching or sharp pain; gradual onset; ask about activities of repetitive gripping or static contractions of forearm and wrist; identify ergonomic factors that overuse flexors; ask about sudden changes in activity level (poor conditioning); may be pain with shaking hands; ask about symptoms related to nerve pathologies (cubital or carpal tunnel syndromes or pronator teres syndrome)
Observation: not inflammatory; unless periosteal tear or enthesitis (but not visible); may se cubital
valgus but structural not necessarily a symptom
Palpation: tenderness and pain at flexor tendon attachment at medial epicondyle; wrist flexors feel hypertonic; pain increased if wrist put in extension and muscles/tendons palpated; fibrotic or ropy feel; may be referrals from trigger points near elbow or forearm when forearm muscles palpated (n: deep papation)
Range of Motion and Resistance Testing:
AROM: pain possible with wrist flexion if severe; as condition worsens, less force required to cause pain; pain at end ROM with extension as tendons stretched; pain may also occur at end range of supination as pronator teres stretched
PROM: pain at end range with wrist hyperextension as tendons stretched and end range of supination if pronator teres involved
MRT: pain with wrist flexion; pain with pronation if pronator teres involved; weakness possible due to reflex muscular inhibition
Special Tests:
( n: MRI+press)
Golfer’s Elbow Test:standing/seated; therapist grasps patient’s elbow so thumb presses on flexor tendons distal to attachments at medial epicondyle; therapist’s other hand offer resistance to patient’s wrist flexion; offer resistance only, do not push; engaging wrist flexors causes pain at medial epicondyle as tensile force added; pressing on tendons while in contraction, stress to damaged tissues is exaggerated
Differential Evaluation: arthritis, pronator teres strain, cubital tunnel syndrome, cervical radiculopathy, pronator teres syndrome, median nerve compression near elbow, thoracic outlet syndrome, ulnar collateral ligament injury; osteochondritis dissecans, epicondylar apophysitis, stress fractures, ulnar nerve pathology, flexor muscle strain
Suggestions for Treatment: treated conservatively; ultrasound, stretching, ROM exercises and electrical stimulation; anti-inflammation medications during early stages; deep friction applied directly to affected tendons to stimulate collagen production in damaged fibres; deep longitudinal stripping, myofascial approaches and active engagement beneficial to restore optimum function
Olecranon Bursitis
Common injury conditions
Characteristics: olecranon bursa is superficial to olecranon process of ulna to protect it and reduce friction between bony prominence and overlying skin; primary cause of bursitis is compression of the bursa, followed by inflammation; may be acute injury (direct blow) or chronic compressive loads over time
-can be caused by infection, systemic disorders or medical procedures (kidney dialysis)
History: pain with various movements; if acute, ask about traumatic event; if chronic ask about chronic compression; otherwise consider systemic disorder and refer to physician if not already diagnosed
Observation: large lump on posterior side of elbow; redness and inflammation
Palpation: tender to touch even with mild pressure; excess fluid around elbow; warmth due to inflammation
Range of Motion and Resistance Testing:
AROM: flexion or extension may be painful, more common at end of flexion
PROM: as with AROM
MRT: increase in pain not likely
Differential Evaluation: rheumatoid arthritis, olecranon process fracture, ligament sprain of elbow, synovial cyst, ulnar nerve compression
Suggestions for Treatment: PRICE, avoid compression in treatment, anti-inflammatories and/or antibiotics; no direct massage treatment to bursa
