Several `therapies` have an overtly `religious` component, e.g. reiki may well be. If people are invited to have such `therapies` they should be fully informed of their religious nature.

 

Registrations

Osteopaths and chiropractors have one

 

Potential for harm

Many alternative therapies are potentially dangerous

Serious pathology may be undiagnosed

Potentially effective treatments always have a potential for harm

 

Research

Poorly researched compared to conventional medicine

Picture is confused by publication bias towards positive results; this will distort meta analysis studies

 

Placebo effect

Factors include touching, time spend, quality of communication

 

Beneficial principles

Patient control reduces stress and so promotes healing

Hope can be offered                                                 Touch is a strong placebo

Whole person treatment                                                       Allows for individual expression

Taking the patient seriously                                     Believing the patient

 

Harmful principles

Promotion of denial                                                              False hope

Scope for financial, emotional and sexual abuse  Guru status can lead to cults

Rejection of conventional treatments which sometimes work

 

Acupuncture

Procedure

Needles are left in acupuncture points for 10 – 30 minutes over 6 – 12 sessions

Used for many disorders

 

Mode of action

Qi, yin, yang and meridians probably do not exist

Needles may stimulate A delta fibres which initiate segmental C fibre inhibition

Via midbrain connections there may be inhibition of descending endorphin mediated pathways

Other claims have no physiological explanation

 

Evidence

Some evidence suggests effectiveness in pain, nausea and substance abuse

 

 

Herbal medicine

Until 100 years ago most medicine was herbal

 

Differences with pharmacy

Herbalists use the whole plant to gain synergistic effects. This also promotes `buffering` where one alkaloid reduced the toxic effects of another.

Herb combining is also used for synergy and buffering

These effects account for variations in dose of active ingredients

 

Differences with medicine

History taking and diagnosis is different

Many ethnic groups have their own systems, e.g. Ayurvedic medicine in India

 

Evidence

Some evidence exists, e.g. ginger for nausea and vomiting, feverfew for migraine prophylaxis, ginkgo for cerebral insufficiency and dementia, St. Johns wort for depression.

A combination of 10 Chinese herbs has been shown to be highly significant in refractory eczema using a randomised crossover study.

 

Risks

Many plants are highly toxic.

 

Homeopathy

Background

Like cures like as opposed to alagopathic medicine

Preparations are usually from plant or animal products which are diluted

Claim to treat a wide range of disorders

 

Evidence

Some trials show an effect greater than placebo, others do not

No evidence exists for water memory

 

Risks

Only failing to use conventional medicine, the preparations are safe

 

Hypnosis

Hypnosis is a state of increased suggestibility

 

Uses

Addictions, psychosomatic illness, evidence levels are low

 

Risks

False memories, psychological problems, bring on latent psychosis

 

Meditation

Probably not a good idea

Some exercises used may promote subtlety, but also carry risks in some groups

 

Osteopathy

Manipulation of bones, joints and connective tissues using manual manipulative techniques.

 

Techniques

`High velocity thrust` is often used and produces cracking sounds in a joint

`Functional techniques` include traction with rotation

 

Some use craniosacral techniques which are probably useless, they are used to manipulate `subtle rhythmic pulsations in the CSF` which probably do not exist

 

Risks

25 – 50% of patients have some pain at the manipulation sites for up to 24 hours

Practitioner must be aware of contraindications to particular manipulations

Clearly there are risks in such a physical treatment, cervical spine in particular

 

Evidence

Several published trials do show benefit over conventional treatments in back and neck pain

Studies cannot be blind

 

Chiropractic

Similar to osteopathy but focuses on spinal manipulation

 

Massage

Most cultures seem to have developed massage techniques, e.g. China, Thailand, India

 

Indications

Promote relaxation, treat anxiety, treat painful muscular conditions

May generate ascending inhibition as explained by gate theory

Some claim to improve circulation and lymphatic drainage

Muscle knots probably do not exist

Very good for babies and young children who can not talk, good for bonding

 

Evidence

Some evidence that massage can reduce anxiety scores with a possible cumulative effect

 

Risks

Injury to internal organs                                 Avoid DVTs and skin injuries

Avoid direct pressure over tumours            Close physical contact is often associated with sex

 

Massage with smelly things

`Essential oils` may be toxic in high doses and are probably useless

Smells may be used as aids to association

 

Reflexology

Massage of particular areas of the foot

Can feel relaxing but has no scientific basis at all as far as is known

 

Nutritional therapies

Much dietary manipulation is conventional, e.g. high fibre diet, plenty of fruit and veg, fish oils for arthritis, gluten free in coeliac disease etc.

 

Use of nutritional supplements

Fat and water soluble vitamins       

Vit C and zinc offer some prophylaxis for the common cold

B6 for premenstrual features and autism                                       Vit E for angina

 

Use of inclusion diets

Inflammatory bowel disease

 

Use of exclusion diets

Hyperactivity                          Migraine                     Rheumatoid arthritis

 

 

 

Homeopathy

 

 

Do you think all people who call themselves scientists can be trusted to be correct?

 

 

 

Do we know of any physiological mechanisms which would explain why like should cure like?

 

 

 

Dose homeopathies sometimes seem confused between the concepts of symptomatic management as opposed to treatment of the underlying cause?

 

 

 

At a 12C dilution the concentration is equivalent to one drop in what?

 

 

 

At a 30C solution are there any of the original molecules left in a homeopathic dilution?

 

 

 

Can the personality of a leader or guru figure influence the thinking of otherwise dispassionate

people?

 

 

 

Is the concept of blindness important in research?

 

 

 

Can detailed interviews and lots of personal attention have a therapeutic effect?

 

 

 

What factors could influence the effect of homeopathic preparations in humans?

 

 

 

What factors could influence the effect of homeopathic preparations in humans?

 

 

 

Is it important to remove human subjectivity from research?

 

 

 

Can you think of anyone or any claim which could win a million dollars if their claims were correct?

 

 

 

Is homeopathy safe, does in have any side effects

 

 

Are our conventional treatments always safe?
