Scoliosis – Key points

This article will summaries key points on Scoliosis

There are three types of structural scoliosis

1) Idiopathic

2) Congenital

3) Paralytic

 

1. Idiopathic scoliosis is perhaps archetypal and most well-recognised.

- It is a genetic/hereditary condition of poorly understood pathogenesis
- Majority is “adolescent idiopathic scoliosis” – i.e. develop between age 10-18
- Incidence between male and female is the same but female has 10 x more likelihood to progress
- Vast majority of the curves are convex to the right at thoracic spine

 

Scoliosis

 

2. Congenital scoliosis is essentially a birth defect and not that common.

(Below is an example of congenital scoliosis before and after a corrective surgery)

Congenital scoliosis

 

3. Paralytic scoliosis is secondary to a pre-existing condition that had resulted in paralysis and scoliosis consequent to that.

- e.g. post-polio, cerebral palsy, post-stroke

 

The above three types of scoliosis are STRUCTURAL – i.e. “true scoliosis”.

There is non-structural scoliosis that can be frequently observed – often called “postural”. They require little intervention, other than some general advice in regards to exercises and encouragement to correct

 

Adams forward bend test is the simplest test that can help differentiate structural from non-structural.

Adam's forward bend test

 

Cobb angle: choose the most tilted vertebrae above and below the apex of the curve. The angle between intersecting lines drawn perpendicular to the top of the top vertebrae and the bottom of the bottom vertebrae is the Cobb angle.

Cobb angle

Cobb angle plays an important part in overall assessment and plan of management of Scoliosis (see below).

--

Intervention can consist of four types:

- observation
- scoliosis-specific exercises (reasonable evidence for this for those even with significant Cobb angle).
- orthopaedic braces (best in combination with scoliosis-specific exercises)
- surgery

This direct from Horne et al (2014):

 

“Determining which patients need referral to an orthopedist can be complicated, and clear indications are not always available. The risk of spinal curve progression increases with higher Cobb angle and lower Risser grade. However, the trend in recent years is that fewer patients need radiography, and fewer patients who undergo radiography need treatment. Treatment modalities such as physical therapy, chiropractic care, and electrical stimulation have questionable benefit in preventing scoliosis progression. Bracing and surgery are options, but the evidence for them is limited. A 50-year follow-up study of late-onset idiopathic scoliosis including 117 untreated patients and 62 age- and sex-matched volunteers found that patients with untreated scoliosis are productive, are high-functioning, and usually have little physical impairment other than back pain and cosmetic concerns.”

What is physiotherapy? – 2018

chronic-pain-physiotherapy-Francis-Joung

 

I had a solid discussion with a bunch of physiotherapy students the other day.

 

Especially on the topic of why they chose physiotherapy profession as their careers.

Then I asked them a question:

"What is your understanding of what physiotherapy, the very profession that you have chosen as your careers?"

The answers were, rather disappointing. They recited something that was still pretty much what I was taught back in the late 90's.

So here is what I believe physiotherapy should be, as in 2018. Please click here.

Brief overview of Primary Headaches

migraine headache

 

Brief overview of Primary Headaches

According to the International Classification of Headache Disorders 3rd ed (www.ichd-3.org), there are four types of primary headache disorders:

1. Migraine
2. Tension-type headache
3. Trigeminal autonomic cephalalgias
4. Other primary headaches

Differentiation of the abovementioned types can be difficult. So here is a quick overview.

1. Migraine

Diagnostic criteria for migraine WITHOUT aura (1):

 

A. At least five attacks fulfilling criteria B-D

B. Headache attacks lasting 4-72hr

C. Headache has at least two of the following four:

1. unilateral location
2. pulsating quality
3. moderate or severe pain intensity
4. aggravation by or causing avoidance of routine physical activity

D. During headache at least one of the following:

1. nausea and/or vomiting
2. photophobia and phonophobia

 

(for criteria for migraine with aura - go to www.ichd-3.org/1-migraine/1-2-migraine-with-aura/)

2. Tension headaches

Clinically, migraine and tension headaches are the most common. Goadsby (2) comments:

"Migraine at its simplest level is headache with associated features, and tension-type headache is otherwise featureless."

3. Trigeminal Autonomic Cephalalgia (TAC):

TAC is headache with prominent ipsilateral cranial parasympathetic autonomic features such as lacrimation, rihnorrhea, nasal congestion, eyelid edema, ptosis etc.

4. "Other primary headaches"

are clinically heterogeneous. These include primary exercise headache, cold-stimulus headache, and many others.

The pathophysiology of the headaches

is, in short, poorly understood. However current understanding is that most primary headaches have something to do with “neurovascular involvement of trigeminovascular system" (2) that consist of the following key structurs:

- the large intracranial vessels and dura matter
- the peripheral terminals of the trigeminal nerve that innervates these structures
- the central terminals and second-order neurons of the trigeminal nucleus

trigeminovascular system

It is proposed that these structures undergo pain-inducing process, resulting in sensitisation of nociceptors, vascular changes (e.g. vasodilation), and other phenomena including autonomic symptoms (2-4). Vascular changes were once considered as the major cause; that is no longer the case. Instead central sensitization and sensitization of the nociceptors at the trigeminovascular system is seen as the major contributor (3-5).

Diagnostic Criteria for Complex Regional Pain Syndrome

1102-f1

Complex Regional Pain Syndrome Diagnostic Criteria 

Definition of CRPS:

"CRPS is a syndrome characterized by continuing (spontaneous and/or evoked) regional pain that is seemingly disproportionate in time or degree to the usual course of pain after trauma or other lesions. The pain is regional (not in a specific nerve territory or dermatome) and usually has a distal predominance of abnormal sensory, motor, sudomotor, vasomotor edema, and/or trophic findings. The syndrome shows variable progression over time."(1)

It was for some time called "Reflex Sympathetic Dystrophy" but this is usually no longer advocated due to the murky implications that come with "reflex", "sympathetic" and "dystrophy". However some choose to still use the name for CRPS that follow a traumatic injury (CRPS 1).

Budapest Criteria(2), established in 2007, remains as the diagnostic criteria of choice for health professionals worldwide. It is fairly straightforward:

 

Budapest Clinical Diagnostic Criteria for Complex Regional Pain Syndrome

1. Continuing pain, which is disproportionate to any inciting event

2. Must report at least one symptom in three of the four following categories:

• Sensory: reports of hyperesthesia and/or allodynia

• Vasomotor: reports of temperature asymmetry and/or skin color changes and/or skin color asymmetry

• Sudomotor/edema: reports of edema and/or sweating changes and/or sweating asymmetry

• Motor/trophic: reports of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin)

3. Must display at least one sign at time of evaluation in two or more of the following categories:

• Sensory: evidence of hyperalgesia (to pinprick) and/or allodynia (to light touch and/or deep somatic pressure and/or
joint movement)

• Vasomotor: evidence of temperature asymmetry and/or skin color changes and/or asymmetry

• Sudomotor/edema: evidence of edema and/or sweating changes and/or sweating asymmetry

• Motor/trophic: evidence of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin)

4. There is no other diagnosis that better explains the signs and symptoms

Fibromyalgia – diagnostic criteria

Back in 1990, American College of Rheumatology devised a diagnostic criteria for fibromyalgia(1).

i) widespread pain in combination with

ii) tenderness at 11 or more of the 18 specific tender point site

This was REVISED by the same group in 2010(2), and it still is the current recommended diagnostic criteria:

(and it unfortunately is slightly more tricky. Note "tender points" is no longer a valid criteria).

 

A patient satisfies diagnostic criteria for fibromyalgia if the following 3 conditions are met:

1) Widespread Pain Index (WPI) ≥ 7 and Symptom Severity (SS) scale score ≥ 5 or WPI 3–6 and SS scale score ≥ 9.

2) Symptoms have been present at a similar level for at least 3 months.

3) The patient does not have a disorder that would otherwise explain the pain.
