SAT 3/20 Excerpt from: Requirements and Procedures for Firefighter Candidates Tracy Wilson It can be extended at the discretion of the Personnel Department. Which of these BEST defines the word discretion as it is used in this sentence? A) efforts B) judgment C) advancement D) highest percentage

Answer 3/20 B is correct The correct answer is judgment. The definition of the word discretion is judgment. In context, this option is the only one which can replace the word discretion.

What are the phases of healing and why are they important to therapeutic exercise?

Inflammatory Response Phase- Begins immediately following injury
Lasts approximately 2 to 4 days Fibroblastic Repair Phase-Lasts approximately 4 to 6 weeks after injury Regeneration and repair of the injured tissue Maturation-Remodeling Phase- Long-term process May require several years to complete Realignment and remodeling of scar tissue according to the stresses placed up on it

Therapeutic Exercise

Overview Therapeutic exercise-
Goal: return the injured athlete to activity in a safe and timely manner

Components-1 Immediate first aid and management
Begins immediately after injury Very critical; impacts course of rehabilitative process Controlling swelling R-rest I-ice C-compression E-elevation

Components-2 Reducing or minimizing pain RICE Therapeutic modalities

Components-3 Restoring range of motion
Injury always followed by some degree of ↓ROM Limiting loss and ↑ROM back to normal or better is important for any rehab program PROM AROM

Components-4 Restoring muscular strength, endurance, and power
Essential to restoring function of body to pre-injury status Strength-ability of muscle to generate force against some resistance Endurance-ability to perform repetitive muscular contractions against some resistance for an extended time Power-ability to generate force rapidly

Components-4 Isometric contractions-contraction while muscle length remains constant Isotonic-contraction while the length of the muscle changes Concentric contractions-contraction while muscle is shortening Eccentric contractions-contraction while muscle is lengthening Isokinetic contractions-muscle contraction that occurs at a constant velocity

Components 4- Closed chain-exercises that are performed when feet or hands are weight bearing Open chain-exercises that are performed when one foot or hand is not in contact with the ground or some other surfaced

Components 4- Overload principle-for a muscle to improve in strength, it must be forced to work at a higher level than it is accustomed to Exercises are progressively increased depending on the healing process

Components-4 Progressive Resistive Exercises-strengthen muscles through ROM with some fixed resistance Use isotonic contractions Circuit Training-exercise stations that consist of various combinations of activities Plyometric Exercise-involves a rapid eccentric stretch of a muscle followed immediately by a rapid concentric contraction

Components-5 Reestablishing neuromuscular control
Production of coordinated movements Strength exercises (especially functional one) help body “relearn” movements need to perform tasks of sport

Components-6 Regaining balance Essential athletic skill
Lack of balance may predispose one to further injury or reinjury

Components-7 Maintaining cardiorespiratory fitness
Levels of cardiorespiratory fitness may decrease rapidly when athlete is injured Alternative activities may be implemented until at the appropriate point in healing process for others

Components-8 Functional progressions
Series of gradually progressive activities designed to prepare athlete for return to a specific sport Sport specific activities

The steps of therapeutic exercise are on a continuum much like the healing process.
Progression from one component to the next should be guided by the healing process and the patient’s body and injury.

Critical Thinking A soccer player has been diagnosed as having a grade 2 MCL sprain. The team MD reffered her to PT who is in charge of her rehab program. What are the STG og a rehab program, and how can these be achieved?

SAT 3/21 The new country lay open before me: there were no fences in those days. Sometimes I will follow the sunflower-bordered roads. What grammatical error occurs in this sentence? A) wrong noun form B) wrong verb tense C) subject-verb disagreement D) pronoun-antecedent disagreement

Answer 3/21 B is correct The sentence's grammatical error is wrong verb tense. The surrounding sentences use past tense verbs ("lay" and "were"), but the last sentence in the excerpt suddenly changes into a future tense verb ("will follow") which makes little sense with the adverb "Sometimes" (implying something that happpened in the past) and with the other past tense verbs used in the previous sentence. The verb tense that should have been used in the sentence was "followed."

Injury Treatment

Injury Treatment 2 areas Therapeutic Modalities Therapeutic Exercise

Therapeutic Modalities
Non-exercise treatment options Include the use of: Heat Cold Electrotherapy Massage Traction Ultrasound Compression Vocabulary Indications-reasons/injuries where it is appropriate to use the modality Contraindications-reasons/injuries where it is inappropriate to use the modality

What are indications

What are contraindications

Thermal Modalities Transfer energy to or from the tissues; exchange of energy based on a temperature gradient Energy transferred through Conduction-between two objects that are touching Convection-movement of a medium (water, air) Radiation-transfer without the use of a medium Conversion-energy changed to another form Evaporation-liquid to gas state

Thermal Modalities Cryotherapy-application of cold modalities Effects:
Vasoconstriction Decreased rate of cell metabolism Decreased production of cell waste Reduction of inflammation Decreased nerve conduction Decreased pain Decreased muscle spam Decreased muscular force production

Thermal Modalities Cryotherapy Types: Ice bag Ice cup Cold whirlpool

Electrical Stimulation
Electrical stimulation-modality that utilizes electrical currents Electricity-force created by an imbalance in the number of electrons at two points (poles) Electrons flow in an attempt to equalize difference in charges—this creates an electrical current Negative pole-area of high electron concentration Positive pole-area of low electron concentration Closed circuit-formed when a complete path is formed between the 2 poles Electrical Currents Direct Current-uninterrupted, one directional flow of electrons; square wave Alternating Current-direction of flow changes from positive to negative in a cyclical manner; no true positive or negative poles; electrons go back and forth between electrodes Pulsed Current-one direction of flow that is interrupted by periods of no current flow

Vocabulary Electrode leads-wires that conduct the current to and from the generator, electrodes, and patient Electrodes-introduce the current into the body; point where the electrode contacts the skin is where the electrons are converted into ions When placed closer together, current flows superficially When places farther apart, the deeper the current flows

Indications Controlling acute and chronic pain Reducing edema Reducing muscle spasm Reducing joint contractures Inhibiting muscle spasms Minimizing disuse atrophy Facilitation tissue healing Facilitating muscle reeducation Facilitating fracture healing Strengthening muscle Contraindications Cardiac disability Pacemakers Pregnancy (over abdomen, pelvis, and lumbar regions) Menstruation (over abdomen, pelvis, and lumbar regions) Cancerous lesions Sites of infection Exposed metal implants Areas of nerve sensitivity Carotid sinus Esophagus Larynx Pharynx Around or on eyes Upper thorax Temporal region Severe obesity Epilepsy Electronic monitoring equipement
