Study Notes

Center of Mass

Center of mass is the central point where gravity acts on a body or segment, often referred to as the center of gravity.
In a standing position, the center of mass is located in the pelvic region, anterior to the S2 vertebra.
The center of mass shifts when body segments change position, weight is added or removed, or the object's position changes.

Base of Support

The base of support is the area where an object makes contact with its supporting surface.
A larger base of support increases stability as it allows more space for the center of mass to be within the base of support, and it decreases stress on the clinician.
A smaller base of support decreases stability, leading to a higher risk of the center of mass being beyond the base of support, increasing stress on the clinician.

Posture

A plumb line is an imaginary line that represents the ideal alignment of the body in an upright position.
The plumb line should pass through specific landmarks in a lateral view, including the external auditory meatus, acromioclavicular joint, midway through the trunk, greater trochanter, fibular head, and anterior to the lateral malleoli.

Stability and Mobility

Stability refers to how well something stays put.
Mobility refers to how easily something can move or be moved.
Stability and mobility are related to the center of mass and base of support.

Promoting Stability and Mobility

To promote stability, increase the base of support, ensure the line of gravity is at or near the center of the base of support, shorten the distance between the center of mass and base of support, and lower the center of mass closer to the base of support.
To promote mobility, decrease the base of support, allow the line of gravity to move beyond the center of the base of support, and increase the distance of the center of mass above the base of support.

Body Mechanics

Body mechanics refers to the coordinated effort between the musculoskeletal and nervous systems to maintain balance, posture, and body alignment during tasks.
Proper body mechanics can reduce stress on body structures, promote efficient and safe movements, maintain control and balance, conserve energy, and support effective respiratory and cardiopulmonary function.
Correct posture and body alignment help maintain the normal spinal curves.

Basics of Lifting Mechanics

The 5 L’s to lifting principle:
- Load: Plan ahead by estimating the load and clearing the path of travel.
- Lever: Consider the distance from your center of gravity to the object.
- Lordosis: Maintain proper posture and normal lumbar curvature.
- Legs: Use legs to lift.
- Lungs: Exhale during lifting, avoiding the Valsalva maneuver.

Load

Plan ahead by mentally and physically preparing for the lift, ensuring a safe environment, considering patient safety and contraindications, determining the need for individual or team lift, and communicating with the patient and team.

Lever

Position yourself close to the load for stability and reduced muscle activity.
Maintain a wide base of support by standing with feet apart, one foot slightly in front of the other, and toes pointed slightly outward.

Lordosis

Maintain normal spinal curvature, a slight inward curve of the low back, and look ahead rather than downwards.
Keep your chest facing forward and avoid twisting at the trunk, particularly if flexed.
Pivot on feet or take small steps to rotate the body.

Legs

Bend at hips and knees for a squat lift, lowering the body's center of mass for stability.
Lift with an upright trunk, normal spinal curvature, and engage trunk muscles before lifting.
For pushing, utilize a wider base of support, lower center of mass, and larger muscles.

Legs Variations

Half Kneel (Tripod Position): Begin behind the object, remain upright, place the object on your knee, and push through the forward leg.
Golfer’s Lift: Used for lighter objects, lift by flexing at the hip and reaching forward while resting on a single leg.

Lungs

Exhale during exertion to prevent the Valsalva maneuver and reduce intra-abdominal pressure.

No Skipping Leg Day

Maintain your lifting equipment, strengthen your muscles, improve flexibility, and engage in aerobic conditioning.
Avoid prolonged sitting and prioritize regular movement.

Draping

Draping procedures in physical therapy settings maintain patient privacy, modesty, and dignity.
The general procedures for draping involve:
- Before Treatment: Plan ahead, cover treatment areas, obtain consent, provide temporary clothing, and ensure privacy.
- During Treatment: Provide initial overall coverage, expose only the necessary area, secure edges, minimize exposure time, and layer draping materials.
- After Treatment: Provide specific dressing instructions, ensure privacy, dispose of draping materials, and sanitize.

Draping Purposes

For the clinician: Necessary access to specific body areas for examination and intervention.
For the patient: Protection of privacy, modesty, dignity, cultural safety, warmth, comfort, protection of vulnerable skin (wounds, surgical sites, scars, neurologically impaired areas), and protection of clothes.

Maximize Comfort and Dignity

Utilize verbal and non-verbal communication, obtain consent, provide adequate coverage, and ensure privacy (secured door, curtain, room divider, leave room upon request, suggest assistance).
Provide clinical attire, cover clothes with temporary linens, minimize exposure (amount of area exposed and length of time exposed), and layer draping materials.
Secure edges to increase a sense of security by tucking along the body and clothes.

Patient Positioning

Supine: Examination of the anterior trunk and lower extremities.
Prone: Examination of the posterior neck, trunk, and lower body.
Sidelying: For individuals unable to lie prone.
Sitting: Linens may slide off, so layer and tuck linens.

Adjusting Positions

Provide additional linens for coverage during transition.
Hold coverage in place during transition and re-secure once repositioned.

Lines, Tubes, and Drains

Be aware of common lines and tubes utilized for medical care to ensure safe mobility and avoid kinking, pulling, stretching, or dislodging.
Be aware of potential challenges such as pain, neuromuscular impairments, sedation, and side effects from medications, especially in an ICU environment.

Vital Signs Monitoring

Be aware of ECG leads, blood pressure cuffs, pulse oximeters, temperature monitors, and respiratory rates.

Lines and Tubes; Head and Neck

Nasogastric (NG) Feeding Tube: Inserted through the nose, esophagus, and into the stomach for administering liquid nutrition.
Nasoduodenal Tube: Similar to the NG tube, but ends in the duodenum.
Nasal Cannula: Flexible tube delivering supplemental oxygen, used for conditions requiring additional oxygen.
Tracheostomy: Alternative way of breathing through a tube inserted into the trachea, used for airway blockage, mucus clearing difficulties, and long-term breathing support.

Lines and Tubes; Upper Extremity

PICC Line (Peripherally Inserted Central Catheter): Longer and thicker central venous catheter inserted peripherally in an extremity.
Peripheral IV (Intravenous Device): Placed peripherally on an extremity, used for drawing blood and administering treatments.

Lines and Tubes; Torso

Percutaneous Endoscopic Gastrostomy (PEG) Tube/G-tube: Feeding tube inserted into the stomach or duodenum, requiring an upright position during feeding.
Chest Tube: Flexible plastic tube inserted into the chest wall and pleural space to remove air or fluid.
Ostomy Bag: Surgically created opening in the abdomen to collect waste or urine, often with a bag placed over it.

Drains
