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.

Anatomy
• Muscle
• Tendon

Muscle
• Are responsible for
essentially all body
movements and can be
viewed as the “machines”
of the body.

Tendon
• Is a tough band of fibrous
connective tissue that
connects muscle to
bone, or muscle tomuscle and is designed
to withstand tension.

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

Epidemiology
• It can affect anyone, most especially the active ones
• Athletes
• Performing artists
•Social workers
• Computer gamers
next

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.

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.

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.

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

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
8/13/2019 Overuse Syndrome
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

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
