MC/Strength/Endurance of Trunk Flashcards

1
Q

Core Stability Definition

A

Core stability is a base or platform of musculoskeletal strength (and endurance) that results in (neuromotor)control of the trunk and allows optimal performance of limb activity.

Cervical and scapula stability as well

Stabilization of trunk to advance the function of the limbs.

Q

Which muscles are the most important? Why?

A
  • None of them AND all of them
  • No one muscle contributes greater than 30% of the overall stability of the lumbar spine. Stability is dependent on all muscles
  • Contibutions from each muscle continually changes throughout a task

Q

Usual Examination findings associated with Trunk Motor Control/Strength Deficits

A

Subjective
* History of back/hip pain OR neck/shoulderpain
* Especially history of persistent symptoms (“chronic”)
* Symptoms usually associated with static postures and/or asymmetric “loading” of the spine.
* Symptoms increase as the day progresses

Posture: Poor postural awareness (aka body positioning)
AROM: Imparied QUALITY of motion especially with functional motions. “Abberant motion”
Palpation: associated with tenderness of tonic muscles
Motor: Poor activation of muscles and poor endurance

Q

What is the order we provide interventions for muscles?

A

Activation -> Strength -> Endurance

Applies to lumbo-peliv and cervico-scap

17
Q

What muscles in the lumbo-pelvic would you consider go from activation into endurance? How do we progress them to endurance?

A
  • Deep abdominal/multifidus/pelvic floor
  • Quadratus Lumborous
  • Gluteus maximus
  • Gluteus Medius
  • Progress all to endurance activities by increasing hold times
18
Q

What are the Interventions for the Cervico-thoracic-scapular region?

A
  • Enhance Movement Coordination(Scapular and humeral dissociation). From previous weeks
  • Proprioception and rhythmic stabilization.From previous weeks
  • Interventions to minimize tone of tonic muscles: Stretching and/or Soft tissue mobilization. From 1st ½ of semester
  • Enhance motor function:
    – FIRST: Neuromuscular control (activation) andendurance of the “phasic” muscles
    – SECOND: Strength/Endurance of the phasic andtonicmuscles

In this order!

19
Q

What cervico-scapular muscles need to go from neuromuscular control -> strength -> endurance? How can we progress to endurance?

A
  • Deep neck flexor
  • Deep neck extensor
  • Lower trap and rotator cuff
  • Serratus Anterior
  • Progress all to endurance activities by increasing hold times
20
Q

What is the order for interventions to enhance motor function of the trunk?

A
  1. Education
  2. Dissociation of movement patterns
  3. Minimize tone/irritability of tonic muscles
  4. Neuromuscular control, Strength AND endurance
21
Q

Patient Education for trunk control

A
  • Educate patient that injury and pain affects muscle function

“Your condition (pain, injury, neuro condition, etc.) affects how the muscles function. Because the muscles are not functioning optimally it may be contributing to your symptoms. It is important first to retrain the muscles to function on command and THEN improve strength or endurance of muscles”

22
Q

Marathoner vs Sprint analogy - Patient Education on phasic/tonic muscles

A

Marathoner: Deep stabilizers are phasic muscle
Sprinters: Superficial – primary movers, tonic

Sprinters don’t like marathoners. Get sore results in irritability of muscles. Get the irritability to go away by getting the sprinters to train like sprinters not marathoners

23
Q

Facilitate Femoral and Pelvic Dissociation in Lumbo-Pelvic-Hip

A
  • Pelvic mobility in sagital and horizontal planes is important to establish PRIOR to strengthening exercises (ie: pelvic clocks)
  • Once patient has awareness of movement, educate on concept of “neutral pelvis”
24
Q

What is considered “NEUTRAL PELVIS and NEUTRAL SPINE”?

A
  • Neural position: between anterior and posterior tilt end range. Up to patients decision. Working on maintaining this position.
  • Struggles because of lack of proprioception and lack of dissociation.
  • Can be found by the patient in supine, sitting and standing
25
Q

Facilitate scapular and humeral dissociation of the cervico-thoracic region

A
  • Scapular dissociation: Scapular clocks
  • Humeral dissociation: Isolated humeral motion on fixed scapula
  • Once patient has awareness of movement, educate on concept of “ideal neck and scapular position”
26
Q

What is considered “Ideal neck and scapular position”?

A
  • Posterior neck elongated with ear over acromion
  • Scapula rested on rib cage with scapular in mid-range between end range protraction and retraction.
  • Can be found by the patient in supine, sitting and standing
27
Q

Minimize tone/irritability of tonic muscles via stretching or Soft tissue mobilization - Primary muscles to target

A

Primary muscles to address in lower quarter:
* Erector spinae
* Adductors
* Hip flexors
* Hip rotators
* Hamstrings
* Quadriceps

Primary muscles to address in upper quarter:
* Pec minor
* Upper trap and levator
* Scalenes

28
Q

What are the four stages of neuromuscular control/strength/endurance?

A

Stage 1: Activation stage
Stage 2: Static stabilization stage
Stage 3: Dynamic stabilization stage
Stage 4: Activity specific training

Stage 1&2 – Local Training (Deep stabilizers, phasic muscles)
Stage 3&4 – Global Training (primary movers, tonic muscles)

29
Q

Stage 1: Activation

A
  • Teach individual to recruit muscles on command with “ideal” posture (ex: teach deep abdominal activation in neutral pelvis/spine)
  • Especially important with deep abdominals/ multifidus/pelvic floor and gluteals in lumbo-pelvic-hip region
    – Keep pelvis in “neutral alignment” and activate these muscles
  • Especially important with lower trap and deep neck flexors and rotator cuff in cervico-thoracic-shoulder region
    – Keep scapula and c-spine in neutral
30
Q

Stage 2: Static Stabilization

A
  • Teach to maintain static alignment of the pelvis/lumbar spine or scapula/CT region
  • Impose specific demands (commonly unilateral to challenge transverse plane) on the lower or upper extremity as patient maintains static position of pelvis/lumbar spine or scapula/CT spine
  • Work in variety of planes of movement
  • Add resistance only if needed. Typically, these are “body weight exercises”
31
Q

Stage 3: Dynamic Stabilization

A
  • Impose specific demands on the lower and upper extremity as patientmoves through the range of motion of lumbopelvic or scapulothoracic region while resistance is applied.
  • Be sure to avoid painful motion
  • In other words, the patient no longer stays in neutral or ideal spine position (into functional movements
  • Work in variety of planes of movement
  • Resistance is provided as needed
32
Q

Stage 4: Activity Specific Training Examples

A

Squats, Rows, Overhead throw, lunges, activity specific training

33
Q

Example: Deep Abdominal Program in Supine

A
  • Stage 1 find neutral pelvis. Activate muscles palpate medial to ASIS.
  • Stage 2: Creates a rotational stressor to the trunk but in a stabile position; maintain neutral in transverse and sagittal plane.
  • Stage 3: Bring both knees up and to 90 degree angle; have them extend hip and control eccentric motion down and concentric back up; less stable BOS. Touch heel come back up.
  • Stage 4: Extend legs straight out, the farther you go the farther it goes. Doing one at a time introduces the transverse plane.
  • Each demand greater force on iliopsoas and therefore puts more demand on spine.

“Don’t let your fingers move” – Hands on ASIS; External Cue

Illiopsoas: Anterior aspect of spine and iliac fossa
Deep abdominal, PF: prevent tilting of spine.

34
Q

HEP Dosage

A

Depends on goal of exercise!

Muscle Activation
High Reps and low hold times (1 sec - frequently through the day)

Strength
Sets and reps with appropriate resistance (based on what patient can tolerate). To enhance force production, usually 2-3 sets of 8-12 reps
Establish goals for patients on how MUCH RESISTANCE they can tolerate

Endurance
Work till “form failure” – OR – till symptom provocation
Use time NOT sets and reps. Perform the activity for a period of time vs. providing sets and reps.
Establish goals (in seconds or minutes) for patients on HOW LONG THEY CAN perform the exercise
