One of the first questions that potential FES Cycling system owners might want to know is how much does a system cost? I guess from a potential client’s point of view there is not a lot of point in finding out about all the features and benefits if the cost is out of reach. In this article I can give you some guidance on the approach to pricing we apply to our RehaMove FES Cycling range.

Although pricing will obviously depend on the exact specification of a system, I can do my best to explain some of our thinking at Anatomical Concepts. We haven't set out to offer the least expensive or the most expensive FES bike and ultimately you will judge for yourself whether we offer good value.

We should shortly see the emergence of new spinal cord stimulation products that can assist rehabilitation, as the first examples are approaching commercialisation. Although not a cure for spinal cord injury, these devices have been shown to assist in the recovery of function in situations where this seemed lost for ever.

Spinal cord stimulation (SCS) has a rich history that dates back to the 1960s, when it was first introduced as a potential treatment for chronic pain management. Pioneered by Dr. Norman Shealy (1967) this innovative method was initially developed to alleviate intractable pain by delivering mild electrical pulse trains to the spinal cord via implantation of electrodes.

Over the years, the field of SCS has witnessed significant advancements in both technology and research, broadening its potential applications to include functional recovery following spinal cord injury (SCI).

This article looks briefly at the state of the art.

How to we test for denervated muscle? As we will see in this article, a number of conditions can lead to denervation. Sometimes the extent of this denervation is hard to establish with equipment commonly available to the therapist. Perhaps the therapist tried “conventional” neuromuscular electrical stimulation (NMES) and could not produce a muscle contraction even with quite high intensity settings. Hence denervation was suspected, but without really being able to determine it’s extent.
The RISE stimulator provides a handy protocol that allows the presence and extent of denervation to be established and monitored over time. This article describes the process. First lets review some information on what exactly causes denervation, it’s consequences and the benefits of electrotherapy. We can then describe how the RISE unit can give is a denervation “benchmark”.

Functional Electrical Stimulation, or FES for short, is a very powerful tool in the hands of a capable therapist but is sadly still poorly understood and less often seen in clinical practice than it deserves. I think there are a number of reasons for this.
The first problem is perhaps the fact that using electrical energy for therapeutic effect has a long and sometimes colourful history. This may have led to the whole idea of using electricity as being associated with “quackery”.

Another problem has perhaps been the fact that FES requires some technical as well as clinical know-how. It should be obvious that the nature and form of the electrical energy should be well understood as this is necessary for safe and effective application. This is not helped by the fact that there is no consistent use of terminology and practical guidance is often lacking about evidence supporting it’s use.

In this article, we look at the efficiency of FES Cycling and see that there is actually lots of room for improvement when it comes to metabolic efficiency and power output.

Of course that does not mean that they should not be used. Much research over decades shows the benefits for users from regular training. FES Cycling performance is good enough to produce results if people use these products. The benefits are greater than those via passive cycling alone.

However, any engineer who looks closely at the technology will realise that there is much that can be improved when it coms to FES cycling exercise. This is what engineering aims to do - refine and improve things for the benefit of society. Improving the technology could produce a greater health benefit for the same or less effort so it's worth striving for. It should also be said that this is no trivial challenge. All electro-mechanical systems that interact with the human body tend to offer design difficulties that are not obvious to the casual observer.

Combining a passive/active exercise bike with synchronised FES (Functional Electrical Stimulation) is a well-researched and well-known exercise modality for persons to use after a spinal cord injury or other neurological condition.  One of the benefits often sought by our spinal cord injured clients is preservation of bone density and we will look at the evidence for this in this article. Bone is a dynamic tissue - it responds to the needs placed upon it - getting stronger under load and weaker in the absence of load. Paralysis after a spinal cord injury and lack of activity that loads the bones results in a loss of bone strength and increased risk of fractures.. FES Cycing is one way of helping to prevent this.
