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 Precautions:
-
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.
- Supine to Sitting:
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.
