Q

define chronic pain

A

Pain that continues after you would have expected the tissues to have healed is more related to other pain mechanisms i.e. you would not expect a “sprained ankle” to still be painful after 3 months so symptoms are more likely to stem from a neurological problem

Q

what is the Mature Orgaism Model

A

It suggests that pain is not just caused by tissue damage or injury, but also by how the brain interprets that damage based on several factors, such as past experiences, emotions, and the current environment.

Q

explain in simple terms the Mature Organism Model

A
  1. Signals from the body: When something happens to the body, like an injury, signals are sent to the brain through the nervous system.
  2. Brain’s role: The brain doesn’t automatically assume pain just because of these signals. It checks various factors—like whether you’ve been injured before, how dangerous the situation seems, or what your emotions are at that moment.
  3. Brain decides: Based on this information, the brain decides whether or not to create the sensation of pain.
  4. Response: If the brain believes the body is in danger, it creates pain to get you to act (like moving away or stopping an activity). But if the brain thinks the situation is safe, it might reduce or ignore the pain.

Q

What causes injury in tissues according to mechanotherapy?

A

Injury occurs when a tissue is stressed beyond its ability to cope, leading to deformation and eventually micro-failure.

Q

What is the goal of physiotherapists during injury rehabilitation in mechanotherapy?

A

The goal is to make the tissue more load-tolerant by controlled tissue damage to shift the micro-failure point further along the graph.

Q

How does tissue respond to loading in mechanotherapy?

A

Tissue deforms slowly at first, then more rapidly until micro-failure occurs. Beyond this point, injury happens as the load curve plateaus.

Q

What is proprioception?

A

Q

What impact does joint inflammation have on movement?

A

Joint inflammation can disrupt proprioceptive feedback from mechanoreceptors, leading to reduced joint stability and impaired movement control.

28
Q

What are the three main sources of sensory information for postural stability?

A

The three main sources of sensory information for postural stability are somatosensory feedback, vestibular feedback, and visual feedback.

29
Q

What is somatosensory feedback?

A

Somatosensory feedback provides information from the skin, muscles, and joints about body position and movement relative to the environment.

30
Q

What is vestibular feedback?

A

Vestibular feedback comes from the inner ear and provides information about balance and head position relative to gravity.

31
Q

How should the three sensory systems be considered for progression in movement training?

A

All three systems—somatosensory, vestibular, and visual feedback—should be considered and progressively challenged to improve postural stability and movement control.

32
Q

How do tissues adapt to physical stress?

A

Tissues alter their structure and composition to meet the mechanical demands of routine loading.

33
Q

What provides a stimulus for tissue adaptation?

A

Deviations from routine or steady-state loading provide a stimulus for tissue adaptation.

34
Q

What is achieved within certain thresholds during tissue adaptation?

A

Tissue adaptation occurs within the lowest and highest loads required to produce a specific tissue response.

35
Q

How many qualitative responses to physical stress are there?

A

There are five qualitative responses to physical stress depending on the level of load.

36
Q

what are the 5 qualitative responses to physical stress

A
  • permanent damage
  • injury
  • increases stress tolerance (atrophy)
  • maintenance (tissue homeostasis)
  • atrophy in response to reduce load
37
Q

What does tissue homeostasis refer to?

A

Tissue homeostasis is the balance between cellular breakdown and growth.

38
Q

How much load can uninjured biological structures handle while maintaining tissue homeostasis?

A

Most uninjured biological structures can handle loads ranging from below one to almost eight times body weight and still maintain tissue homeostasis.

39
Q

What is supraphysiological overload?

A

Supraphysiological overload is low-level cellular tissue damage caused by repetitive low load (e.g., distance running) or a single high load (e.g., a rugby tackle).

40
Q

What happens when tissues are allowed sufficient recovery before repeated loading?

A

tissues adapt, become stronger and more tolerant to further loading

41
Q

What happens to tissues at the supraphysiological level?

A

Tissues are weakened, and if subjected to further repeated loads, they are likely to deteriorate and result in tissue failure.

42
Q

what is mechanotransduction

A

mechano transduction is the process by which cells convert mechanical stimuli into biochemical responses

43
Q

what are the steps of mechanotransduction

A
  1. mechanocoupling
  2. cell-to-cell communication
  3. the effector response
44
Q

describe the third step of mechanotransduction (the effector response)

A

increased protein synthesis and therefore the addition of tissue in response to stress loading.

45
Q

describe the first step of mechanotransduction (mechanocoupling)

A

physical load (often shear, tensile or compression) causes a physical perturbation to cells that make up a tissue.

46
Q

describe the second step of mechanotransduction (cell-to-cell communication)

A

This causes deformation of the cell that results in a cascade of chemical responses both within & between cells. The extent of the response depends on the magnitude & duration of the load.

47
Q

What is critical when balancing progressive tissue overload in strength training?

A

Finding the balance between progressive tissue overload and manipulating the training program (e.g., FITT principle) without causing reinjury.

48
Q

What is the result of exercise training over many weeks and months?

A

Increased muscular endurance, which enhances work capacity.

49
Q

How is strength-endurance targeted in strength training?

A

By exercising at 40-60% of 1 rep max (RM) for over 15 repetitions with short rest periods (<90 seconds).

50
Q

How often should strength training be performed for untrained individuals?

A

At 8-12 RM, 2-3 times per week.

51
Q

How should strength training be performed for trained individuals?

A

At 1-6 RM with 3-5 minute rest periods.

52
Q

What are the morphological responses to strength training?

A

Increases in cross-sectional area, muscle pennation angle, fascial length, and fiber type changes.

53
Q

What are the neurological factors involved in strength training adaptation?

A

Motor unit recruitment, firing frequency, motor unit synchronization, and intermuscular coordination.

54
Q

Why is a needs analysis important in strength training?

A

To set appropriate goals specific to the needs of the patient.

55
Q

what is phase 4 of msk rehabilitation

A

return to functional activity, sport and work

56
Q

What should be assessed regarding the person’s role or position in a sport or activity?

A

The person’s specific role or position within the activity or sport should be evaluated.

57
Q

What should be considered about performance duration?

A

The total duration of the person’s performance, along with the duration and frequency of training sessions.

58
Q

What needs to be assessed in terms of activity duration?

A

Whether the activity is continuous or involves bursts of varying intensity and duration.

59
Q

What types of physical activities should be considered in a training program?

A

Jumping, landing, sprinting, changing direction, kicking, throwing, lifting, and carrying.

60
Q

What should be considered about impact and contact in activities?

A

The involvement of impact, contact, and collisions in the sport or activity.

61
Q

What should be evaluated in terms of distances and directions in an activity?

A

The distances covered and the directions moved during the activity.

62
Q

What needs to be identified regarding muscle involvement?

A

The predominant muscle groups and muscle actions involved in the activity.

63
Q

What flexibility and range of motion (ROM) demands should be assessed?

A
