No, I haven't gone mad!! This is not about the cost of takeaway food to Law Enforcement Officers. What have these three acronyms in common - the answer is the evolving treatment of injury. We all are told of conflicting advice about what to do with an injury. "To ICE" or "not to ICE", 'To Rest' or "too much rest is bad for you". This blog hopes to answer some of those questions. If you are not familiar with the acronym R.I.C.E., it is the often used treatment for acute injury and stands for: R - Rest I - Ice C - Compress E - Elevate However this conflicts with the Chinese Medicine concepts of injury management.. The Classical Chinese Medicine (CCM) paradigm holds that pain is caused by stagnation - and whereas the CCM paradigm approves of Rest (in the early stages at least) and Elevation (to help in the reduction of swelling) it tends not use Ice or Compression, since it is felt that these two will increase stagnation and may slow the healing process. CCM prefers to utilise herbal poultices or plasters that are energetically cooling, but still promotes moving of Qi and Blood (including lymph and other fluids). If plasters were not available, then a cold compress in the initial stages could be used (but for no more that 5 minutes every hour) to help with the acute pain. This dichotomy often led to heated discussions between myself and some of my Western Medicine tutors - however it seems that the ICE model may be due for an upgrade !! Latest research seems to support the idea of Resting for the first 24-48 hours after acute trauma to stop further injury (Bleakley et al, 2012) - however too much rest can actually cause more harm than good (hence that is why many post-surgical regimes have patients up and mobile much sooner than was the case 10 or 20 years ago). It seems that excessive rest can cause joint stiffness and weakness and may lead to a change in biomechanics due to adaptation and compensation by neighbouring structures, increasing the possibility of re-injury. Again, according to that 2012 study the evidence supporting the use of Ice is mainly anecdotal (focusing mainly on its analgesic effects) together with the use of compression. As was pointed out by Dr Bahram Jam from the Advanced Physical Therapy Institute (Jam, 2020) humans have spent about 7 million years evolving an effective method of tissue repair post injury - initiated by the inflammatory response. Inflammation prevents further damage, stops infection and kick-starts the repair process (termed proliferation and remodeling). Blood vessels dilate and become 'leaky' (permeable) thereby; Allowing the arrival of white blood cells (leukocytes) to kill off any infection and to signal reinforcements (in the shape of cell eaters or macrophages) to help mop up the damage.; Any waste products and excess fluid are then removed by the lymphatic system - which (unlike the cardiovascular system) does not have its own pump and relies mainly on movement, skeletal muscle contraction and breathing for lymphatic drainage. Whereas icing modulates pain, it also limits muscle contraction (Bleakley, 2012) which may then also temporarily effect lymphatic drainage at the site. Ligaments and tendons, both of which have a poor blood supply normally, may be adversely affected by too much ice, which constricts blood vessels and theoretically may reduce healing. The ICE model was then revised to PRICE,. However the model currently in favour is P.O.L.I.C.E.: P - Protection - this aims to reduce further damage to the injured area by using devices (such as crutches, braces or supports - traditionally associated with rest) to avoid complete rest and still move, whilst protecting the area; OL - Optimal Loading - this refers to the start of gentle movement of the injured area. Controlled mechanical loading up-regulates gene expression of proteins that are used in soft-tissue healing (Bleakley, 2012) thereby prompting healing at a cellular level. The problem is that if tissues are stressed to much, too early further damage could be caused. Guidance can be given at the clinic regarding exercises that progressively load the area to promote healing and increase proprioception. Optimal Loading also prevents problems such as muscle tightness or muscle wasting that can happen form too much rest; I - Ice, applying ice (putting a towel between the ice pack and skin, avoiding ice burns) to the injured area for 10 minutes every 2 hours; C - Compression - gentle compression of the injured area with a bandage may minimise swelling - however insure there is not skin colour changes or pins-and-needles since it may be too tight; E - Elevation In addition, the use of Anti-Inflammatory pain killers (e.g. Ibuprofen) in the acute stages (usually 24-48 hours post injury) is now frowned upon since, as had been described, inflammation is required for the healing process and a key response to tissue damage. If necessary, paracetamol could be used for analgesia. Click here to download a brief advice leaflet, or look at the video below for further information.
