stage 1 ulcer
characterized by an observable pressure related alteration of intact skin whose indicators, as compared to an adjacent or opposite area of the body, may include changes in skin color, temp, stiffness, or sensation.
stage 2 ulcer
partial thickness skinloss that involves the epidermis and/or dermis. Superficial and presents as a clinical abrasion, a blister or a shallow crate.
stage 3 ulcer
full thickness skin loss that involves damage or necrosis of subcutaneous tissue that may extend down to but not through, the underlying fascia. Presents as a deep crater with or without undermining adjacent tissue.
stage 4 ulcer
full thickness loss with extensive destruction, tissue necrosis or damage to muscle, bone or supporting structures.
Inspiration muscles
Diaphragm (main)
Upper trapezius
External interostals (Secondary)
Expiration muscles
Internal intercostals (main)
superficial burn
involves only the outer epidermis .
red with slight edema
No scar healing in 2-5 days
super ficial partial thickness burn
involves the epidermis and the upper portion of the dermis.
Painful with blisters
Healing occurs in minimal to no scaring in 5-21 days
a deep partial thickness burn
complete destruction of the epidermis and upper portion of the dermis
discolored with broken blisters/edema
Damage to the nerve endings may result in only moderate pain
Healing for hypertrophic scars and keloids in 21-35 days
full thickness burn
complete damage of epidermis and dermis and partial damage to subcutaneous fat layer
eschar formation
no pain
require grafts and susceptible to infection
Compression garments:
10mmHg: not adequate edema control
- 16-18mmHg: off the shelf stockings used to prevent DVT in bed ridden patients.
- 20-30mmHg: used to control scar tissue formation.
- 30-40mmHg: used to control edema in ambulatory patients.
Best indicator that the pt. exerted maximal effort
failure of the heart rate to increase with further increases in intensity
acceleration
rate of change in velocity with no respect to time
cadence
number of steps taken by a person per unit in time
110 steps typical in male
115 steps typical in female
velocity
rate of linear forward motion in the body
measured in cm per sec
= distance dived by time
Grade 1 Joint mob
small movement performed at beginning of range
Grade 2 Joint mob
II large amplitude movement performed within the range, but not reaching limit of range and not returning to beginning of range
Grade 3 Joint mob
large amplitude movement performed to limit of range
Grade 4 Joint mob
small amplitude movement performed at limit of range
Direct current
uninterupted flow of electrons toward the positive pole. This type of current is necessary to move the charged ions across the dermal barrier. Polarity remains constant and is determined based on treatment goals and the polarity of the chosen ion.
Alternating current
biderictional, constantly changing continous flow of electrons. negative to posisitve
Pulsatile Current
3 or more pulses grouped together.
interferential current
combines 2 high freq alternating waveforms that are biphasic. delivered through 2 different electrode in2 different channels.
Intermittent claudication
An aching, crampy, tired, and sometimes burningpain in the legs that comes and goes – it typically occurs with walking and goes away with rest – due to poor circulation of blood in the arteries of the legs. In very severe claudication the pain is also felt ar rest.
Nerve pain
sharp shooting burning
M.m pain
cramping dull achy
worse when mm stretches
Bone pain
deep intolerable and highly locolized
Vascular pain
diffuse, throbbing aching, and poorly locolized
Glossopharyngeal breathing
used to increase vital capacity and clear upper airway in
patients with paralysis of some of the respiratory muscles
The pedal pulse
The pedal pulse is the anterior tibial artery that supplies the musculature of the anterior compartment of the shin. Obstruction of this artery is anterior compartment syndrome
Electrocardiogram lead I?
The negative lead is on the right arm and the positive lead is on the left arm
Electrocardiogram lead 2?
The negative lead is on the right arm and the positive lead is on the left foot
Electrocardiogram lead 3?
The positive lead is on the foot and the negative lead is on the left arm
Hydrostatic pressure
affects the chest expansion, decreasing it. This decreases
inspiratory capacity, thus the vital capacity.
the best pulmonary pattern to monitor to indicate the significance of
the patient’s disability:
Inspiratory reserve volume, tidal volume, vital capacity, total volume
Reason: The tidal volume and vital capacity indicate the patient’s ventilatory function.
insidious onset
should lead the therapist to explore disease as an etiology for this
problem. The most common are metastatic cancer, idiopathic frozen shoulder, and
arthritis.
edema compression
has shown that two hours of intermittent compression will achieve the best
edema reduction.
galvanic simulation
is characterized by high voltage, pulsed
stimulation and is recommended primarily for local edema reduction through pumping
and polarity effect. The galvanic stimulation thereby applies an electrical potential which
disperses the negatively charged proteins away from the edematous site and helping to
reduce the edema. 50Hz is chosen over 30Hz as this is sufficient for muscle
contraction
Contrast bath
Hot 5 min, cold 1 min, hot 5 min.
Ratio of 3:1 or 4:1(hot: cold) for 19-20 minutes is fairly well
accepted.
Traction of lumbar spine:
traction of lumbar spine: typically 25% of patients body weight is generally recommended when the goal of treatment is to decrease muscle spasm or stretch soft tissue.
50%: required for mechanical separation of lumbar spine.
mechanical agent: traction
modality that applies mechanical forces to body to separate joint surfaces and decrease pressure. force can be applied manually by therapist or mechanically by a machine.
therapeutic effects of traction
joint distraction, soft tissue stretching, muscle relaxation, reduction of disk protrusion, joint mobility
indications for traction
nerve impingement, herniated or protruding disc, subacute joint inflammation, spondylolisthesis, joint hypomobility, paraspinal muscle spasm, degenerative joint disease, osteophyte formation
contraindications for traction
when motion is contraindicated, joint instability, tumor, pregnancy, acute inflammatory response, acute sprain, osteoporosis, fracture
treatment parameters for traction
treatment time is 5-20 mins. cervical: pt supine with approx 25-35 degrees of neck flexion, should start with a force btwn 10-15 lbs and progress to 7% of pt’s body weight as tolerated for separation of vertebrae. lumbar can be supine or prone, and should be set with a force of less than half body weight for initial treatment. traction force of 25-50 lbs is recommended when initiating mechanical lumbar traction. force of up to 50% of body weight is required for actual separation of the vertebrae.
