Introduction to the Pain and Movement Reasoning Model[edit | edit source]

When considering the psychosocial factors affecting the patellofemoral joint, even though the pain and movement reasoning model was not designed for patellofemoral pain, the theory can be effectively applied.

When applying this model to patellofemoral pain, local stimulation consists of factors such as bone oedema, fat pad swelling, effusion, retinacular ischaemic changes, bone bruising, or anything local at the knee. Regional influences include excessively pronating feet, an anteverted femoral neck or poor hip abduction control. But there is not much available research to show the role played by the central nervous system.

Factors in the Pain and Reasoning Model[edit | edit source]

  1. Local Stimulation[1][2]
    1. Biomechanical Stimulation
    2. Chemical Stimulation
  2. Regional Influences[1][2]
    1. Kinetic Chain
    2. Patho-neuro-dynamics
    3. Convergence
  3. Central Nervous System Modulation[1][2]
    1. Prolonged Afferent Input
    2. Predisposing Factors
    3. Cognitive - Emotive - Social state

Mindfulness[edit | edit source]

When patients had patellofemoral pain, many of them experienced a sense of loss of identity and a loss of social interactions. When an individual has patellofemoral pain which limits them from participating in their sport of choice, we need to consider that it is not only the activity they are suddenly unable to participate in. They also often loose the sense of wellbeing and social interaction that the sport offered.

Wride[3]'s work shows important correlations with regards to anxiety and depression:

  1. The prevalence of anxiety and/or depression is higher in the patellofemoral population than the normal population. [3]
  2. The prevalence of anxiety and/or depression is higher in young females [3]
  3. High anxiety scores were more likely female[3]
  4. The rate of patellofemoral pain is higher in females[4]

A few patients have even been known the change career aspirations and housing choices because of their patellofemoral pain. An individuals beliefs regarding their knee pain can cause large lifestyle adaptations.

Patients can battle with their understanding of the causes of their knee pain, especially when it is of insidious onset. Unlike a traumatic injury, knee pain of insidious onset is not marked by an event which the pain can be attributed to. This can be influential to the incorrect assumption that exercise can worsen the pain. When a physical therapist then prescribes exercise based treatment, a patient can be hesitant and non-compliant due to their beliefs. The patient should be educated on the effects of load, repetitive volume, warm up, cool down, footwear, and many other facets vital to understanding exercise. Treatments that patients felt were of benefit to patellofemoral pain where often passive, primarily painkillers, knee supports, and rest. While these might help the pain temporarily, they will not be beneficial to the patient in the long term.

A study by Selhorst [5] showed that a short educational video shown to a group of adolescents can reduce kinesiophobia, catastrophisation, pain scores, immediately and at two weeks. This shows the significance of education in patellofemoral pain.

Another factor to consider is the patients sleep. We should look at the only the quantity or duration of sleep but the quality as well. We should be asking questions such as, How many times does someone wake up in the night? How long does it take to get to sleep?

The work carried out by Bagheri[6] showed that when mindfulness was included with physical treatments, there was a greater improvement in pain reduction, catastrophisation, kinesiophobia. The focus of mindfulness is to reduce stress, take control of the situation, stay in control, and not be overly alarmed by it. While as therapists, we are often focussed on reducing pain, if a patient is discharged from treatment with incorrect beliefs regarding their knee pain, they could continue the fear avoidance behaviours and have anxiety while playing their sport.[7] It is important to address the psychosocial factors, as well as the physical ones.

Mindfulness is aimed at increasing awareness of thoughts, sensations, emotions all with an attitude of acceptance, curiosity and openness.[6]

Tampa Scale of Kinesiophobia[edit | edit source]

The original Tampa Scale of Kinesiophobia is (TSK) was first developed in 1991 by R. Miller, S. Kopri, and D. Todd. TSK is 17 items a self-reporting questionnaire based on evaluation of fear of movement, fear of physical activity, and fear avoidance. It was first developed to distinguish between non-excessive fear and phobia in patients with chronic musculoskeletal pain, specifically the fear of movement in patients with chronic low back pain then widely used for different parts of the body. The questionnaire using 4 points to assess that are based on; the model of fear-avoidance, fear of work-related activities, fear of movement, and fear of re-injury.[8]

Psychosocial Factors and How to Address Them[edit | edit source]

Psychosocial Factors[edit | edit source]
  • Depressive symptoms[9]
  • Higher levels of anxiety[9]
  • Fear avoidance
  • Lifestyle changes
  • Kinesiophobia[5][6]
  • Catastrophisation[5][6]
Questions to ask[edit | edit source]
Question Reason Treatment Implication
Duration of symptoms? The longer the duration the more likely there will be central pain changes. Assess for central changes
Alteration in sleep quality? Serotonin (natural painkiller) production suppressed with poor sleep Recommend re-establishing routine. Non-painful exercise.

Decrease anxiety through education

Change in exercise profile? Can affect sleep, mood, self-esteem, social interactions and conditioning. Consider exercise programmes for non-painful body parts initially.

Education to minimise fear-avoidance.

Can they tolerate the sense of clothing on their knee, eg skinny jeans/tights? Some patients cannot bear the feeling of material on their knee. Highly suggestive of non-mechanical pain. Graduated exposure. May need medical management to de-sensitise.
