Study Notes

Special Cases and Considerations

Posterior Approach Total Hip Arthroplasty (THA)
- Positioning Precautions:
  - Avoid hip flexion greater than 60-90 degrees
  - Avoid hip adduction greater than 0 degrees
  - Avoid hip internal rotation greater than 0 degrees
Positioning Following THA
- Side lying positioning with hip adduction is incorrect as this places the hip in a dangerous position
- Alternative Positioning: Use an abduction wedge to prevent adduction
Bed Mobility
- Supine to Sitting:
  - Avoid sidelying
  - Use a push-up strategy to transition to a reclined long sit position. This minimizes hip flexion.

Preparation for Stretching

Choose the appropriate stretch based on the patient's needs and goals.
Warm up before stretching.
Positioning is crucial for safety, comfort, and optimal access.
Explain the stretch and encourage relaxation.

Application of Stretching

Stretch the extremity through its available range. Stabilize the proximal segment while mobilizing the distal.
If a multi-joint muscle is being stretched, focus on one joint at a time.
Gentle distraction can be applied.
Apply low-load stretching in the opposite direction to the pull of the muscle restricting range.
Hold stretches for at least 30-60 seconds.

After Stretching

Engage in active range of motion (AROM) and/or strengthening exercises.
Ensure balance between agonist and antagonist muscle strength.

Adjuncts to Stretching

Techniques like heat (including warm-up), cold application, massage, biofeedback, joint traction/oscillation, and relaxation techniques can enhance stretching programs.

Determinants of Stretching

Factors influencing the effectiveness of stretching:
- Alignment
- Stabilization
- Intensity of the stretch
- Duration of the stretch
- Speed of stretch
- Frequency of stretch
- Mode of stretch

Alignment

Positioning the body ensures that the stretch force is directed to the target muscle group.
Pay attention to the trunk and adjacent joints.

Stabilization

One point of muscle attachment is fixed while the other is stretched.
Often, the proximal attachment is stabilized, and the distal segment is moved during manual stretching.
Self-stretching often stabilizes the distal attachment, while the proximal segment moves.
Be cautious for muscle substitutions during the stretch.

Intensity of Stretch

A low-intensity (low-load) stretch is preferred for better results.
Low-intensity, long-duration stretches:
- Increase range of motion
- Reduce the risk of injury
- Improve comfort
- Elongate dense connective tissue

Duration of Stretch

Shorter duration stretches may require increased repetitions.
Static stretches:
- Hold for durations ranging from 5 seconds to 5 minutes.
- 30 seconds is a common holding time.
- Can be performed as static progressive stretches.
Cyclic (intermittent) stretches:
- Short duration stretches repeated; cycles last between 5 and 10 seconds.

Speed of Stretch

The speed at which the stretch is applied influences its effectiveness.
Slow application:
- Encourages muscle relaxation and prevents injury.
- Easier and safer for the therapist or patient to control.
Ballistic stretching:
- Rapidly forceful intermittent stretching.
- Not recommended for older adults, sedentary individuals, or those with pathology.
High-velocity stretching:
- Rapid low-load stretch.

Frequency of Stretch

Refers to the number of stretching sessions per day and per week.
Recommendation: 2 to 5 sessions per week
Daily frequency may include 1 to 3 sessions.
Rest between sessions is essential for healing and minimizing soreness.
Use clinical judgement and patient response to determine frequency.

Mode of Stretch

How the stretch is applied:
- Static
- Ballistic
- Cyclic
Patient participation:
- Passive
- Assisted
- Active
Source of the stretch:
- Manual
- Mechanical
- Self

Manual Stretch

External force is applied beyond the available range of motion.
Types:
- Controlled, end-range, static, progressive.
Hold for durations varying from 15 to 60 seconds over multiple repetitions.
Effectiveness is not conclusively established for all conditions.
Often used in the early stages of stretching.

Self-Stretching

Patient actively performs the stretch to increase range of motion.
Effectiveness hinges on proper technique and education.
Hold for 30 to 60 seconds.
Ideal for home exercise programs and long-term self-management.

Mechanical Stretch

A device applies a low-intensity force over prolonged periods, promoting tissue lengthening.
Examples:
- Cuff weights/pulley system
- Adjustable orthotic devices
It's crucial to use the newly achieved range after treatment to maintain it.
Hold for 15 to 30 minutes up to 8 to 10 hours; serial casts can be worn for days or weeks.

PNF (Proprioceptive Neuromuscular Facilitation) Stretching Techniques

Includes active muscle contractions to increase flexibility.
Requires voluntary control.
Employs reciprocal inhibition.
Types:
- Hold-Relax (or Contract-Relax)
- Agonist Contraction
- Hold-Relax with Agonist Contraction

Hold-Relax

Isometric contraction of the target muscle group.
Patient relaxes, and the stretch is reapplied.

Steady State

Ability to control center of mass (COM) relative to base of support (BOS) in unchanging conditions.
Stable body, stable surface (static)
Stable body, moving surface (dynamic)
Moving body, stable surface (dynamic)
Examples: sitting on a bench, sitting on a therapy ball, walking on a firm, flat surface

Reactive

Ability to recover a stable position after unpredictable perturbation
Examples: tripping over an object, standing on the metro (accelerates/decelerates quickly)

Anticipatory

Ability to activate muscles to maintain balance before potential destabilizing voluntary movements.
Examples: kicking a ball, reaching for objects on high shelves, picking an object up off the floor

Environmental Considerations

Closed: Predictable with no distractions
Open: Unpredictable with distractions
Lighting: day vs. night, vision loss
Footwear: supportive vs. unsupportive
Hazards: stairs without hand rails, throw rugs, objects on the ground

Support Surface

Stable vs. unstable
Firm vs. compliant
Narrow vs. wide

Primary Physiologic Systems

Neurologic: Input from sensory systems, interprets input into motor strategies
Musculoskeletal: Posture, range of motion, muscle performance
Cardiovascular: Blood flow to the brain

Sensory Organization/Integration

Ability to process various sensory inputs to identify orientation and movement.
Visual
Somatosensory
Vestibular

Motor Strategies for Balance

Fixed: same base of support
- Ankle
- Hip
- Weight shift (lateral)
- Suspension
Change-in-support: change the BOS
- Stepping
- Reaching
Combined Strategies

Fixed Support Strategies

Ankle
Hip
Weight Shift (lateral)
Suspension

Change-in-Support Strategies

Stepping
Reaching

Causes of Balance Impairment

Sensory input:
- Vision: Changes in acuity, contrast, peripheral field, depth perception
- Somatosensation: Peripheral neuropathies, aging, ligamentous injuries
- Vestibular: Viral infections, TBI, aging
Biomechanical and motor output:
- Poor posture
- Joint range of motion restrictions
- Muscle performance deficits (weakness, poor coordination)
- Pain
Sensorimotor integration:
- Reliance on vision/somatosensation
- Damage to central nervous system
Medications:
- Polypharmacy: Taking more than four medications
- Side effects: Hypnotics, sedatives, tranquilizers, antihypertensives, diuretics

Selecting Balance Interventions

Highly individualized based on patient goals and impairments
Considerations:
- Type of balance task
- Level of difficulty: Challenging, but doable
- Dosage: Repetitions or time
- Safety: Always maintain safety

Modifications to Balance Interventions

Identify appropriate challenge:
- Too Easy: Always successful
- Too Hard: Never successful
Progressions and Regressions:
- Base of support
- Use of hands/upper extremities
- Type of surface
- Use of vision

Maintaining Safety

Gait belt
Guard where patient is most likely to fall
Environment setup:
- Stable surface nearby
- Away from sharp edges/objects
- Level of distraction
Safe footwear:
- Supportive sneakers, grippy socks
Applies to clinic and home exercise program

Summary

Postural control (balance) is complex with interactions between person, task, and environment.
Several physiologic systems contribute to balance: nervous, musculoskeletal, and cardiovascular
Various fixed and change-in-support motor strategies used to maintain balance.
Three types of postural control: steady-state, anticipatory, and reactive.
Determining appropriate intervention depends on the patient's goals, the type of postural control affected, level of difficulty, dosage, and the PT’s ability to maintain safety.
