How long does heat therapy last?
Most of these heat modalities are used for short periods of time, for example, 20 minutes maximum. Many studies have shown that short duration of heat application caused minimal, if any, change to skin temperature. Therefore, in deep injuries, heat application for short duration seems to cause pain relief through the gate control theory of pain in the central nervous system and not through the effects upon the peripheral nervous system.
How does heat affect pain?
According to a review by Petrofsky and colleagues, the effect of heat on pain is mediated by heat sensitive calcium channels. These channels respond to heat by increasing intracellular calcium . This, in itself, generates action potentials that increases stimulation of sensory nerves and causes the feeling of heat in the brain. These channels are part of a family of receptors called TRPV ( Transistor Potential Receptor Potential Vanillioid ion channel), which are sensitive to heat. Once activated, they can also inhibit the activity of purine pain receptors, which are located in the peripheral small nerve endings. For peripheral pain, for example, heat can directly inhibit pain. However, when pain is originating from deep tissue, heat stimulates peripheral pain receptors, which can alter what has been termed “gating” in the spinal cord, thereby reducing deep pain.

How to use heat for back pain?
Heat is used in different modalities in the treatment of back pain and muscle soreness. Dry heat can be applied through either heat packs [2] or techniques that warm tissue such as diathermy and ultrasound [23-25]. Heat packs can be dry or moist. Hydrocolator heat packs are usually at 165 deg F and are separated from the skin by 6 - 8 layers of towels and used only in clinical settings [17]. Hydrotherapy (warm) uses water at 105 deg F and involves immersing a limb in the water. Hydrotherapy can include contrast baths or simply warm water immersion [17]. A major problem with this type of heating is that it is usually used for short periods of time, for example, 5 - 20 minutes. Moist heat, in most studies, appears to be advantageous in pain relief to many short duration dry heat modalities such as electric heat pads [15, 26]. But all of these heat modalities are used for short periods of time, for example, 20 minutes maximum. Many studies have shown that short duration of heat application results in poor heat transfer to deep tissues [3, 15, 17, 27]. Therefore, in deep injuries, heat application for short duration causes pain relief through the gate control theory of pain in the central nervous system and not through the peripheral nervous system. Long term application of heat, such as in chemical heat wraps, solves this issue by applying heat for hours to warm deep tissue gradually [28, 29]. But dry chemical heat wraps heat deep tissue much slower that pain relief is delayed by at least 30 minutes. A faster heating modality is chemical moist heat. Here, heat penetration is fast but the duration of chemical moist heat is usually between 30 minutes and 2 hours [15]. The question, then, is how moist and chemical dry heat compare for healing and pain relief. This study compared chemical moist heat lasting 2 hours to dry heat lasting 8 hours to distinguish which heat modality worked best on the symptoms of delayed onset muscle soreness.
How does heat affect pain?
The effect of heat on pain is mediated by heat sensitive calcium channels [5]. These channels respond to heat by increasing intracellular calcium [6, 7]. This, in itself, generates action potentials that increases stimulation of sensory nerves and causes the feeling of heat in the brain [8]. These channels are part of a family of receptors called TRPV receptors [7]. TRPV1 and TRPV2 channels are sensitive to noxious heat [7], while TRPV4 channels are sensitive to normal physiological heat [7, 9]. These channels have in common their sensitivity to other substances such as vanilla and menthol [10]. These multiple binding sites allow a number of factors to activate these channels. Once activated, they can also inhibit the activity of purine pain receptors [11]. These receptors, termed P2X2 and P2Y2 receptors, are mediated pain receptors and are located in the peripheral small nerve endings [11]. For peripheral pain, for example, heat can directly inhibit pain [12]. However, when pain is originating from deep tissue, heat stimulates peripheral pain receptors which can alter what has been termed gating in the spinal cord and reduce deep pain [13].
