Physiotherapy works
Physiotherapy is an important part of the interdisciplinary management of patients
with pain. An optimal course of treatment focuses on counselling, physical activation
and supervised progressive exercises over a period of 2-3 months.
Physiotherapy
for patients
What is pain?
Pain is a cardinal symptom of many diagnoses related to injuries and diseases of nerves,
muscles and joints
(1,2). Pain is frequent and almost one in five Danes is affected by persistent
pain
(1-3). For the individual, pain is an unpleasant sensory and emotional experience
associ-ated with actual or potential tissue damage
(4). Pain not only reflects the sensory experience
associated with tissue damage, but also involves thoughts and an emotional response in
the form of psychological distress. Psychological distress may be expressed as low mood,
anxiety, restlessness, anger and a lack of belief in one’s ability to cope
(4-6). Pain ranges from
the acute pain associated with a physical injury to persistent pain, which often serves no
useful purpose. The complexity of persistent pain may be due to the fact that there is often
no clear correlation between the pain experienced and the physical or diagnostic imaging
findings
(7-12). Pain is also influenced by a variety of biopsychosocial and demographic factors,
for example, gender, age, social status, education, employment status, concomitant
disea-ses, ability to cope and legal and compensatory issues
(4,13-16). The development of persistent
pain and the degree of pain experienced by the individual therefore depend on several of
these factors.
Pain varies. If the patient is to achieve the optimal result of the treatment, it should
be based on knowledge of the underlying pain mechanisms. For example, the treatment
should take into account whether the pain is acute or persistent and whether the underlying
cause of pain is malignant or benign. The practitioner should evaluate the extent to which
the pain is of inflammatory, neuropathic or unknown origin
(4,17,18). In the case of acute pain,
the objective of physiotherapy is to perform a clinical examination, advise on appropriate
relief and normalise the patient’s customary level of physical activity, and possibly provide
pain-relieving therapy
(4,19). When pain is persistent, physiotherapy contributes to the
inter-disciplinary clinical evaluation and the choice of the best documented therapeutic strategy.
The physiotherapist’s work may, for example, consist of counselling, self-help guidance,
pa-tient education in pain management techniques, pain treatment and progressive exercise
(20-25)
. Through clear communication, the patient will be supported in understanding,
mana-ging and coping with his or her situation and the course of therapy
(26,27). These interventions
aim to relieve pain and re-establish the patient’s usual level of physical activity, capacity to
work and social engagement to the extent possible.
THE EFFECT OF PHYSIOTHERAPY
The effect of the various physiotherapy interventions is measured by pain reduction,
impro-vement of everyday functions and quality of life. Here it is important that the effect of such
interventions is clinically relevant and meaningful for the patient and not just statistically
significant
(28,29). An improvement in pain relief and functional improvement of least
30-50% is considered relevant
(30). If the outcome of an intervention is below 30%, the effect is
considered minimal and not clinically relevant. The treatment effect can, however, only be
considered meaningful when it is consistent with the patient’s perception of pain reduction
and improvement of function
(30,31). In the following, we will describe the effect of
physi-otherapy from randomised clinical trials, systematic reviews and clinical guidelines relating
to the treatment of common persistent pain conditions.
Pain and impairment of function caused by osteoarthritis of the knee treated with
pro-gressive, supervised exercise over a period of 2-3 months may have a clinically relevant and
meaningful effect
(32,33). The interventions are function-orientated and focus on increasing
strength, flexibility and aerobic capacity
(1,32). The same effect can be expected from
physi-otherapeutic exercises for subacromial shoulder pain, where the interventions can be
sup-plemented with manual physiotherapy
(34-37).
Physiotherapeutic exercises for non-specific neck pain may also have clinical relevance
(38,39)
. The effect achieved often depends on the intensity, duration and frequency of the
exercises, with more intensive exercises having the best effect
(38,40,41). The exercise can be
combined with manual physiotherapy, which may contribute with minor additional effects
(42-45)
.
The effect of counselling, specific exercises and manual treatment of neck pain
associ-ated with whiplash is minimal and not clinically relevant
(46-48). However, the effect of
phy-siotherapy in patients with whiplash symptoms depends on the degree of biopsychosocial
complexity. In uncomplicated cases, physiotherapy may consist of counselling, self-help
guidance and maintenance of physical activity. In more complex cases, physiotherapy is part
of a comprehensive multidisciplinary intervention, the focus of which is to optimise the
pa-tient’s capability to work, quality of life, health and level of social activity
(47-52).
In non-specific low back pain, physical exercise generally only has a minimal effect, and
in most cases the effect is not clinically relevant
(38,53-59); the same applies to manual and
manipulative treatment
(45,56,60-62). The diagnosis and treatment of low back pain may be a
complex process. Patients with persistent low back pain often have more than one type of
pain, often in combination with neuropathic pain components, comorbidities or complex
psychosocial factors
(63-66). Physiotherapy is, however, an important part of the uni- and
in-terdisciplinary evaluation of such patients in order to identify the optimal individual
treat-ment strategy
(19,63,66). Depending on the degree of complexity, patients need counselling and
self-help guidance to increase their level of physical activity in order to restore or maintain
their ability to work, health and quality of life
(60,67).
Physiotherapy and exercise can contribute with clinically relevant effects in the
manage-ment of headaches and provide important supplemanage-ments to pharmacological treatmanage-ments
(68-74)
. Exercises must be adapted to the specific type of headache, for example, tension-type
headache, cervicogenic headache or migraine. It is important to differentiate between the
different types of headache in order to achieve the optimal effect and to avoid
exacerba-tion of the condiexacerba-tion
(70).The interventions should be adapted to the individual patient and
can comprise relaxation exercises, biofeedback, strength exercise or general fitness training
(69,70,75,76)
. In cervicogenic and tension headaches, a combination of manual physiotherapy and
strength exercises may optimise the outcome of physiotherapy
(74,77-79).
Physiotherapy is an important part of the interdisciplinary treatment of patients with
fi-bromyalgia. In these cases, counselling and physical exercise have clinically relevant effects
and are often superior to pharmacological treatment
(83,84). The physiotherapist may focus
on patient education in pain management and how pain can be controlled and modulated
(23,85). Armed with this knowledge, the patient is well equipped to form suitable strategies
for managing pain, minimising inappropriate behavioural reactions to pain and normalising
functional capability by means of progressive strength and fitness training
(83,84,86).
Physiotherapy is a cornerstone in the interdisciplinary treatment of patients with
neuro-pathic pain and complex regional pain syndrome (CRPS), although the effects are only
mi-nimal, poorly researched or unknown (
87-89). When receiving pharmacological treatment, only
30-40% of these patients can expect more than 50% pain reduction
(90,91).Therefore, these
functional capacity. The contribution of physiotherapy comprises individualised exercises,
pain management strategies, graded motor imagery and mirror therapy
(92-94).
THE SOCIO-ECONOMIC EFFECTS
Pain is one of the most serious issues facing the healthcare sector. The human and
socio-economic costs of treatment, absence due to illness and support allowances are immense
(13,95)
.
In Denmark, the annual social costs of pain-related disorders are estimated to be in
ex-cess of 2.5-3.3 billion €
(1,13,95). Physiotherapy is an important part of the active
interdiscipli-nary rehabilitation of patients with pain. Physiotherapy has been shown to be cost effective
in the treatment of lumbar, knee and shoulder pain when its focus is to provide a cohesive,
active intervention in order to normalise the patients’ physical functional capacity and
op-timise their pain management strategies. This approach has shown that it is possible to
reduce absence due to illness in the long term and to help maintain patients’ capability to
work and optimise quality of life
(67,96-98).
CONCLUSIONS
Pain is a frequent primary symptom in patients who contact the healthcare sector. The goal
of these patients is to restore and regain their level of physical and psychosocial activity to
the extent possible. In the process of achieving this goal, physiotherapy can contribute with
treatment strategies with documented and clinically relevant effects. An optimal course of
treatment initially focuses on clinical examination and diagnosis followed by individualised
counselling, physical activation and supervised progressive exercises over a period of 2-3
months. Physiotherapy is therefore a key component in the interdisciplinary rehabilitation
of most patients with pain.
Physiotherapy is a key component in
the management of patients with:
• Headache • Fibromyalgia • Neuropathic pain
• Complex regional pain syndrome • Low back pain
• Neck pain • Knee pain • Shoulder pain
Fysioterapi er en vigtig del af
behandlingen til smerter ved f.eks.:
• Hovedpine • Fibromyalgi • Neuropatiske smerter • Komplekst regionalt smertesyndrom • Lænderygproblemer • Uspecifikke nakkeproblemer • Knæartrose
The annual social and
healthcare costs of
pain-related disorders are
estimated to be in excess
of 2.5-3.3 billion €
One in five Danes suffer from persistent pain
