These are listed below in the order of their importance/effectiveness (ie their effectiveness for me) Personal Cool and Stretch (after Travell and Simons) [3]Professional
Personal means treatments I applied myself, Professional treatments were ones I paid for. Cool and StretchA description of cool and stretch is given below, quoted from [1]. "The purpose of cooling and stretching is to inactivate the trigger point(s) by inhibiting pain transmission and restoring the muscle to its full range of motion with minimal discomfort. Vapocoolant spray is applied to the skin as a cutaneous thermal stimulus (not to cool the muscle) in unidirectional parallel sweeps. It is applied being sure also to spray the referred pain zone. Cooling to the point of frosting the skin must be avoided. During each sweep of spray steady tension is maintained on the muscle to take up any release of tension which occurs, but carefully avoiding forces strong enough to reproduce the pain . . . . Stretch is facilitated by having the patient breathe in deeply followed by slow and complete exhalation during stretching. Jerky motions or the use of excessive stretching force MUST be avoided as these will reactivate the TP. Following stretching the skin should be rewarmed with a moist heat (moist heating pad or damp cloth over a hot water bottle) . . . [and] the muscle(s) should again be moved through the full range of motion." This method is described in detail, for different affected muscle groups, by Travell and Simons [3], [1] also describes, other methods for deactivating TPs. I found cool and stretch very effective, when done correctly. However, when the problem is bad the TPs slowly reactivate themselves. Thus in order to keep reducing the TPs, or keep them deactivated the cool and stretch needs to be performed regularly.
How often Figure 1 illustrates this process. In my experience cool and stretch is a waste of time if applied only once or twice a week by your physiotherapist. When my condition was worst I used cool and stretch 3-4 times daily. Later I used it only once or twice a day. And after 9 months I used the technique only when I felt I needed it. The method Set up the stretch, apply the coolant, and as it is applied, breathe out and try to relax into the stretch. Hold the stretch for 15-20 seconds. It is very important to properly stretch the muscle without overstretching. The cooling will temporarily stop the pain, but no lasting effect occurs unless the muscle is being properly stretched. It is possible to use ice instead of Vapocoolent spray. The spray is very expensive, a bit smelly, and sometimes difficult to use for awkward stretches. I used well frozen (from bottom of freezer), relatively large ice cubes, with one side/end held with a slightly damp tea towel or cloth (sticks to the ice). Stroke a side of the cube along the TP and referred pain area, (don't hold it on). I have found that, if done properly, one stretch for each TP/muscle is enough for each session, especially if you have many TPs (I had 22 to work on). The area should be rewarmed after cool and stretch. This can be done by taking a hot bath or shower, or by using a heat pad. Such pads can be bought commercially and there are many types. There are special chemical ones that you just press a button on, wheat packs that you heat in hot water, and ones you can heat up in the microwave. Some simpler approaches are to use a hot-water bottle wrapped in a slightly damp towel, or a damp towel placed in the microwave for several minutes on high. This last one is very good for neck areas, as you can then wrap the towel around your neck instead of holding a heat pack against it. Different stretches The correct stretch for the muscle is important. Ask a physio, or find a book of stretches. [1] contains a detailed description of many stretches. However, I found it missing in stretches for hands, and had to invent my own. A summary of these
Experimentation and practice improves the ability to do the cool and stretch correctly. NOTE: The stretching should not be at all painful. If it is you are over stretching, or cool and stretch may not be suitable Ischaemic compression / AcupressureFor ischaemic compression steady pressure is applied to the painful trigger points, with the pressure being slowly increased over 30-60 seconds as the pain diminishes. This good technique is almost as effective as cool and stretch. I found combining both methods, doing a session of ischaemic compression followed by a session of cool and stretch best. I found this technique is also much better applied yourself. Professionals don't have the 'pain feedback' that you have, and often seem to let go too early. Doing it yourself you can apply the technique to your own satisfaction. Using innovative methods to apply pressure Finding a suitable implement to apply the pressure is important, especially if, like me at the time, your arms and hands are very sore. For TPs on my hands and arms I used a small plastic bottle with a smooth pointed lid (5-10 mm diameter - make sure it doesn't have corners or sharp bits)
For my hands and arms I would position the bottle end over the TP then lean my chin on the top to apply pressure, thereby freeing my hands and arms from having to hold it. For the back a good one is to find a suitable door handle, or clothes hook on the wall. Carefully position yourself and lean back against it. Wear some thick clothing to help cushion your skin if the door handle/clothes hook is a bit sharp. For the shoulders, find some piece of architecture that you can stand under and push up against, where a thin piece or outcrop can apply relatively sharp pressure to the TP. Alternatively, of course, you can get a friend / spouse to apply pressure for you under your instructions, using whatever they find convenient (knuckles, fingers, elbow). Doing it right If you are doing it right it will hurt, alot. (When I started the pain was bad enough to make me sweat and feel sick). However the pain should gradually begin to subside. To begin with it won't completely go. But later, (after perhaps many months), at the end of the 60 seconds the area should feel numb. It is necessary, I found, to apply considerable pressure. This pressure might seem too much. To check try applying the pressure to another area that is not tender, when you are pushing too much you will begin to feel a different sort of pain from the TP pain. Though there may be some discomfort, it seems to take alot of pressure to produce this pain on most body areas.
Massage / Deep Tissue MassageDeep Tissue massage involves hard digging and kneading of the area on and directly around the TP, attempting to break up the knot that forms around the TP. I found that deep massage on very painful TPs did not help, and could make them worse. At this stage other techniques were more appropriate, although light, non-painful massage can be relaxing, and perhaps indirectly help relax the TP. Deep massage is good later on when the TPs are mild. See next section for further comments on massage. Muscle StretchesThese are important in regaining range of movement and flexibility, and can help with deactivating the TPs. It is important to do the stretch gently and hold it, for perhaps several minutes (at least 30 secs), whilst trying to relax. At first I would stretch quite hard, thinking the harder I pushed the better the stretch would work. However, I found out after a while that this often made the TP worse instead. There are hundreds of possible stretches. I built up a regime from books, handouts given to me by treatment professionals and made some up. This regime included several stretches for each affected area (neck, shoulders, back, forearms, hands) and I would carry it out several times a day. I found it important to concentrate on doing the stretch properly each time, it was easy to get lazy and go through the motions. I have found that the difference in effects between a stretch done properly and with concentration and one done with little attention is considerable. If not done well they have no effect. Correcting any muscle imbalances Many of the problems of OOS can be exacerbated by postural and muscle imbalances. I was a good example of this. I had done a lot of swimming for many years, which had built up my pectoral and shoulder muscles. I had done stretches after swimming, but usually only stretched the back and trapezius muscles, these were the ones that felt most like they needed stretching. This added to hours spent hunched over a desk, or leaning forward at a computer caused me to develop posture with rounded, lifted shoulders, head forward and down, chin out. This posture greatly exacerbated my shoulder and neck pain, and correcting was obviously important. A physio I saw early on tried to get me to change by pulling my shoulders back, and my chin in. However, although this helped the TPs in my neck I found it very uncomfortable. After persevering in following her advice for many months I eventually developed TPs in my back (trapezius) as well, great. I now believe that such posture correction is impossible without directly trying to correct the muscle imbalances involved, by stretching and strengthening (see later section). I thus did alot of chest/pectoral stretches and neck stretches, trying to lengthen these muscles so as to allow my body to sit comfortably in a correct posture. Nerve stretches may also have an effect upon the TPs. I used nerve stretches alot, though think they have more to do with other types of pain (caused by nerve tension, etc). I have thus discussed nerve stretches later under Neuropathic pain. AcupressureI visited a Chinese acupuncturist, who helped me greatly. I was seeing him twice a week and he would treat me alternately with Acupressure and Acupuncture. The acupressure was akin to a combination of ischaemic compression and deep tissue massage, though not always applied directly to the TP, or painful area. He used very strong treatment for me, occasionally causing minor bruising on my arms / back. However, the treatment had very beneficial results. He would explain it as breaking down the muscle and areas that were causing the problems, forcing them to reheal properly. He said that the treatment should not be done too much, and encouraged me to do exercise to encourage the healing. AcupunctureAcupuncture by itself sometimes offered good pain relief, however, the effects always appeared to be short term. More beneficial appeared to be electrical stimulation applied to the acupuncture needles, usually applied between my wrist/hands and top of forearm, or neck / shoulder. The current was applied at approx. 1-2 pulses per second for 20-40 mins. This treatment appeared to help in reducing the sensitivity of my trigger points, and would also seem to settle my system. It was particularly good for neuropath pain (see later), and later on I duplicated the treatment to some degree using a TENS unit. The electrical stimulation used was usually quite strong, once again, often painful. However, I viewed the pain as a healing pain, and looked forward to the improvements it brought. Usually the pain would subside after 5-10 mins, and often the Acupuncturist would then turn up the stimulation a bit more. I should perhaps make the comment here that pain from recovery techniques was, I found, very common. The pain was often quite strong, but very often appeared necessary to gain good relief and recovery. It is obviously not correct to say that the more it hurts the better it works. Pain is not the aim, but I found that one should not be scared of it, and should not think that pain being felt during treatment is going to make things worse or is an indication of more damage being done. (although sometimes it can be worse for the immediate short term - 1-4 days) Massage / Myofascial ReleaseThis, more general technique, was done for me variously by a physiotherapist, osteopath, and massage therapists. I would, on past experience, not (in general) recommend physios for such treatment, they seem to be much less hands on people, and have less experience at physical treatments. I found it very important to follow advice about doing gentle stretches after the treatments. One very good Osteopath, whom I saw twice a week for many months, would use a systematic regime, massaging along each muscle, then stretching it for me. He would cover all the muscles in the area, not just those immediately sore. Once again deep strong massage was needed. UltrasoundUltrasound was used quite a number of times, on my hands, wrists and forearms. However, I don't really remember it appearing to have much of an effect. I'm told it is meant to help break down scar tissue, however, I always experienced much better results from the other methods described above. For my treatment, at least, ultrasound was at the bottom of the list of helpful treatments.
