Agenda • Reason for today’s visit • Who am I? • Causes of Injuries • Ergonomics • Injury prevention • Apply the principles
Reason for My Visit • Ergonomics • How can we prevent Musculoskeletal injuries? • Organization of work flow • Job Design/Redesign (this includes the environment) • Ergonomic Education • Training • Physical Conditioning & Lifestyle
Who am I? • Registered Occupational Therapist • Promoting health and wellbeing through activity engagement • Solve problems that interfere with your life • Ergonomics • CBI Health Team • Occupational Therapist • Physiotherapist • Chiropractor • Massage Therapist • Kinesiologist
Causes of Injuries • Stress beyond what your body can handle • Sustained Posture • Awkward Posture • High Repetition • High Force • Static Stress = Muscle Fatigue
Ergonomics • Ergonomics is a science concerned with the ‘fit’ between people and their work: ensuring that the job gets done with the least strain on the person doing it.
Anatomy 101: Trunk & Spine Muscles of the front and back support us: • Abdominal muscles and flexible back and leg muscles help maintain good posture. • Muscles across the chest, shoulder blades and neck support the arms & back. • Slouching increases fatigue and makes all the structures work harder to support the back.
Good posture involves training your body to stand, walk, sit and lie in positions where the least strain is placed on supporting muscles and ligaments during movement or weight-bearing activities.
Common Posture Positions: • Sway back • Lumbar Lordosis • Thoracic Kyphosis • Forward Head • Good Posture
Static Sitting • Maintain the spine’s neutral curves • Chair with a lumbar support • Seat should be flat or tilted forward slightly • Bend from the hips when leaning forward • Knees at or above hip level
Neutral Sitting Posture • Knees at same level or slightly lower than the hips with feet on solid surface. • Back against the seat back. At least 3 finger widths between the back of the knee and chair. • Seat back adjusted so it feels good! HINT: try every setting before deciding what feels good! • Arm rests: ~0.5” above and to the side of elbow.
Applying these Principles to your Bus • Circle Check & Static Sitting • Maintain natural S-curve of your spine • Kneel, crouch/squat to avoid stooping • Stair Climbing • 3 point contact • Getting in and out of your seat • Eliminate trunk rotation • Steering Wheel • Shuffle steering rather than full shoulder movement
Prevention - Flexibility • Stretching increases flexibility and decreases risk of injury. • Perform stretches slowly. • Perform stretches multiple times each day.
Exercise Guidelines Consult family doctor Start out easy Increase gradually Exercise regularly A little pain is O.K but should not linger Neck exercises should not cause arm pain Back exercises should not cause leg pain
Prevention – Improve & Maintain Conditioning • FITT Principle • F – Frequency • I – Intensity • T – Type • T – Time
F - Frequency • Schedule it! • Individualized • Start off easy • Anything is better nothing • Must increase frequency as you progress
I - Intensity • Key factor to improve aerobics, flexibility and strength • Start off easy • Progressive overload • Do Not follow the “no pain, no gain” mantra • Apply the conversational intensity • Anything is better than nothing • Individualized
T - Type • Aerobic • Anaerobic • Strength • Flexibility • 30 minutes (only a general guideline) • Work your way up to daily activity T - Time
Stretching & Self Care Stretching improves: • Muscle Relaxation • Circulation • Pain Control • Posture • Stretching decreases: • Injury Risk • Muscle Tension • Low Back Pain • Stress
When to seek further help • Signs & Symptoms of a Larger Problem: • Pain or discomfort during activity that goes away after the activity is done but happens frequently with that activity • Pain or discomfort that lasts after work and doesn’t completely go away before the next work day and/or persists for several days • Funny feelings in the arms/legs: numbness, falling asleep, tingling • Loss of strength • Reduced range of movement If you have these problems talk to your family doctor or other health professional.
