4/20

Overuse Syndrome

• Cumulative Trauma Disorders

• Repetitive Strain Injury

-Repeated, submaximal over-load and/orfrictional wear to a muscle or tendon resulting in

inflammation and pain.

next


5/20

Anatomy

• Muscle

• Tendon

next


6/20

Muscle

• Are responsible for

essentially all body

movements and can be

viewed as the “machines”

of the body.

next


7/20

Tendon

• Is a tough band of fibrous

connective tissue that

connects muscle to

bone, or muscle tomuscle and is designed

to withstand tension.

next


8/20

Etiology

• Imbalance between the length and strength of the

muscles

• Rapid or excessive repeated eccentric demand

• Muscle weakness

• Bone malalignment or weak structural support

• Change in the usual intensity or demands

• Returning to an activity too soon after an injury

• Sustained awkward postures or motions

next


9/20

Epidemiology

• It can affect anyone, most especially the active ones

• Athletes

• Performing artists

•Social workers

• Computer gamers

next


10/20

Pathophysiology

• Proliferation of fibroblasts with increased

collagen production and degradation of mature

collagen leads to a predominance of new,

immature collagen.

• Myofibroblastic activity continues, which may

lead to progressive limitation of motion.

next


11/20

Clinical Manifestations

• Pain in the involved tissue:-when doing repetitive activities

-when attempting to do activities

• Increased swelling and muscle guarding

• Increased feelings of stiffness after rest

• Loss of ROM 24hrs after activity, and progressively

greater stiffness of the tissue as long as the irritation

persists.

• Muscle weakness and poor muscular endurance in

postural or stabilizing muscles

• Decreased functional use of the region

• Faulty position or movement pattern perpetuating the

problem next

Examples of Overuse

Syndromes

• Tennis Elbow

• Golfer’s Elbow

•Carpal Tunnel Syndrome


13/20

Tennis Elbow

• When a person is asked to

actively make a fist, pronate

the forearm, and radially

deviate and extend the wrist

while these movements arebeing resisted.

• There will be a sudden

severe pain in the area of thelateral epicondyle of the

humerus.

next


14/20

Golfer’s Elbow

• While the medial

epicondyle is being

palpated the forearm is

passively supinated andthe elbow and wrist are

being extended.

• Pain is felt in the medial

epicondyle of the

humerus.

next


15/20

Carpal Tunnel Syndrome

• Is a progressively painful handand arm condition caused by a

pinched nerve in your wrist.

• Bound by bones and ligaments,

the carpal tunnel is a narrowpassageway — about as big

around as your thumb —

located on the palm side of your

wrist.• Compression of the nerve

produces the numbness, pain

and, eventually, hand weakness

that characterize carpal tunnel

syndrome. next

16/20

PT Evaluation and

Procedures

• Px education• Promote healing; decrease pain and inflammation

• Maintain integrity and mobility of involved tissue

• Develop support in related regions

• Allow only nonstressful activities

• Modalities

• Stabilization exercises

next


17/20

Rationale of Treatment

• Counsel as to cause of chronic irritation and

need to avoid stressing the part while

inflammed.

• Home exercise program to reinforce therapeuticinterventions.

• Posture training

next


18/20

Precautions and Contraindications

• Weight bearing activities

• Faulty postures

next


19/20

Prevention of Complications

• Do not apply too much pressure on the

involved part

• Protect the affected part

• Use support devices

• Cold, compression, massage

• Rest the part involved• Nonstressful passive movement, massage

and muscle setting within limits of pain
