Chapter 15 Flashcards
Muscle Strains
When muscles are worked beyond their capacity resulting in microscopic tears
Characterized as a sudden tear or Pop sound, usually occurs from abrupt movement
Risk factors: poor flexibility, poor posture, muscle imbalance, improper warm-up, training errors, muscle fatigue, fluid and electrolyte depletion
Ligament Sprains
Usually from a fall during a contact sport or some other trauma
Common: ankle, knee, thumb/finger, shoulder
Symptoms: immediate pain followed by swelling, instability, decreased ROM, and loss of function
Overuse Injuries
Tendinitis
Bursitis
Fasciitis
(Basically all inflammatory responses)
Cartilage Damage
Common: menisci of the knee
Symptoms: clicking, popping, stiffness, giving way, catching, locking
Cause: trauma, degeneration
Bone Fractures
aka Stress Fractures
Causes: falls, trauma, repetitive overuse, car accidents
Common: distance runners, track athletes, volleyball, basketball
Symptoms: progressive pain during weight bearing activity, focal pain, pain at rest, local swelling
Tissue Reaction to Healing
- Inflammatory Phase: lasts for up to six days; immobilizes injured area and begins healing process ; increased blood flow to being nutrients and oxygen to rebuild the damaged tissue
- Fibroblastic/Proliferation Phase: begins 3 days after the injury and lasts 21 days; begin to fill wound with collagen and forms a scar
- Maturation/Remodeling Phase: begins near day 21 and can last for up to 2 years; remodeling of the scar, rebuilding of bone, and strengthening of tissue
Signs of Inflammation
- Pain
- Redness
- Swelling
- Warmth
- Loss of Function
Local Injuries
Exercise Programs should be modified to avoid loading the injured area until physician gives the A-OK to work on that area
Common Symptoms of post-injury/post- surgery overtraining
- Soreness that lasts 24 hours+
- Pain while sleeping
- Soreness or pain from prior session
- Increased stiffness, decreased ROM
- Swelling, redness, warmth in the healing tissue
- Progressive weakness over several sessions
- Decreased functional usage
RICE
The protocol for if an acute injury occurs
R (rest or restricted activity)
I (ice every hour for 10-20 minutes)
C (compression to reduce swelling)
E (elevate 6-10 inch above the heart)
Contraindications to Stretching
- a fracture site that is healing
- acute soft-tissue injury
- post surgical conditions
- Joint hypermobility
- infected area
- hematoma or other trauma
- pain in the affected area
- restrictions from doctor
- prolonged immobilization
- joint swelling from trauma/disease
- osteoporosis or rheumatoid arthritis
- history of prolonged corticosteroid use
Shoulder Strain/Sprain
Symptoms: pain in the shoulder that radiates down the arm
Management: avoid aggravating activities and movements (overhead movements that risk impingement)
Programming:
-educate client how to avoid aggravating movements by improving posture and body positioning
-emphasize regaining strength and flexibility in the shoulder complex by strengthening the scapular stabilizers and rotator cuff muscles
- modify overhead activities so that the exerciser only moves through a partial ROM. Safety is paramount. For example, OH press don’t fully extend the arms
Rotator Cuff Injuries
Symptoms: sudden tearing sensation. Trouble lifting arm overhead
Management: restrict overhead movements and lifting heavy objects
Programming: repair usually takes 6-8 weeks and physical therapy. Clients are usually cleared for the gym after 16 weeks. The goal should be to continue what has been done in physical therapy in a safe, progressive manner
Personal Trainer should receive guidelines as to what movements should and shouldn’t be done. Bending at the arms to create a short lever will create less torque and thus less strain on the healing tissue
Elbow Tendinitis
Cause: overuse of the flexor and extensor muscle tendons of the elbow
Tennis elbow; golfer’s elbow
Common: adults aged 30-55
Symptoms: nagging elbow pain
Management: avoid repetitive wrist flexion/extension activities
Programming: educate client how to avoid aggravating movements, maybe they wear a wrist splint, modify exercises, avoid high reps (15-20 reps) and avoid full elbow extension
Carpal Tunnel Syndrome
Definition: Repetitive wrist and finger flexion when the flexor tendons or strained resulting in a narrowing of the carpal tunnel due to inflammation, which eventually compresses the median nerve
Common: females aged 40-60; bilateral
Symptoms:
-Night/Morning burning
-Loss if grip strength
-Numbness/tingling pain
Management:
-cortisone injections
-wear wrist splints during activity
Programming:
-educate how to avoid aggravating activities
-emphasize regaining strength and flexibility of the elbow, wrist, finger flexors and extensors
-modify movements
-wear wrist splint
-exercise with limited ROM
Avoid:
Full wrist flexion/extension
