Vibroacoustic Harp Therapy in Pain Management
Harp music has been enchanting listeners for thousands of years. The revered instrument of kings, gods, and angels, the harp has historically symbolized a mystical ladder1 connecting this world to the next. Today, the harp is being employed as a therapeutic instrument at bedsides in hospitals, nursing homes, hospices, and other clinical settings, where it symbolizes and serves as a vessel for healing, end-of-life transition, and transformation.
This article will review the uses and benefits of harp music and, more specifically, vibroacoustic harp therapy (VAHT) in a clinical setting.
Harp Therapy as a Healing Instrument
When used as a form of therapy, the harp's music, paired with its aesthetically pleasing image, can provide comfort, distraction, and relief from anxiety and pain; as well as evoke pleasant associations and memories. Therapeutic harpists use the intrinsic healing elements of live music and sound to synchronize a patient's physiological rhythms to the harp music and provide an environment conducive to the healing process. The home or clinical setting largely dictates what size harp (from 22 to 47 strings) can be used (Figure 1, see above). Controlled studies have shown live, bedside therapeutic harp music to be beneficial in reducing pain and anxiety,2-4 stabilizing vital signs,5 and inducing deeper sleep.6 Moreover, in a 2004 survey of 182 patients, families, friends, and staff who were exposed to 25 to 50 minutes of live harp music at Massachusetts General Hospital Cancer Center in Boston, 81% reported increased relaxation and calm mood resulting from exposure to the music.7 End-of-life music vigils also can enable a patient to achieve a peaceful transition.8
Vibroacoustic Harp Therapy
Since its inception in 1990,9 VAHT has reduced pain and pain-related symptoms and has enhanced the quality of life for hundreds of patients. Similar medical benefits from the use of specific low frequencies, embedded into synthesized music in the form of vibroacoustic therapy, have been well documented by Norwegian researcher Olav Skille10 and others.11 During a VAHT session, which often is described as "musical massage," live harp music is amplified through a sound table, chair, or other vibrotactile device (that is, any device that assists the patient in detecting sounds through their sense of touch). After being seated on a vibrotactile device, the patient is asked to focus on areas of tension/pain in the body. During that time, specific tones resonate in those areas and are identified by a dialogue between the patient and the practitioner. Each patient experiences the musical tones in different ways at different times; therefore, the therapy is a very dynamic process and is tailored to the unique individual. Appropriate music is improvised or selected based on the patient's needs.
How it Works
The delivery of amplified acoustic harp music through a vibrotactile device provides a powerful, direct, and immediate effect. The wide range of frequencies and overtones—produced on a harp with a minimum of 36 strings—is capable of vibrating and resonating not only with a patient's dense, physical body, but also with the person's mental, emotional, energetic, and spiritual dimensions. The patient experiences multilevel stimulation and harmonization, thereby activating the parasympathetic nervous system, 12 and synchronizing the diverse oscillatory systems of the body. This is accomplished through the tempo of the music as well as through the resonant, vibratory qualities of the instrument.
Through rhythmic entrainment (the synchronization of organisms to an external rhythm), the heart rate, heart rate variability (HRV), brain waves, and breath begin to work together in a more coherent fashion.13 The indices of physical improvement might include decreased respiratory rate; lowered blood pressure; decreased heart rate; and improved HRV, pain, and symptom relief. According to Mark Rider, PhD, "The brain, mind, and body are harmonically organized. Harmonic refers to a mathematical arrangement in which energy patterns exist in nodes corresponding to whole number multiples of a fundamental frequency, such as [that] found in musical overtones and in the quantum physics of the atom. Furthermore, this harmonic organization enables instantaneous communication among these components."13
When pressure or vibration is applied to the human body, for example, the signal is transduced to an electromagnetic signature. Every cell within the human body vibrates and emits a characteristic electromagnetic signature. According to the latest research in the field of psycho-neuroimmunology, receptors in the cells of the body are activated by specific frequencies and their higher harmonics. These frequencies, which fall within the audible sound range, affect cellular activity in the same way that peptides, drugs, or emotions would. Molecules, located throughout the body, communicate with each other through resonance, through a psychosomatic network of cellular communication, and through a matrix of collagenous fibers. This model accounts for high-speed information transfer, over and above the synaptic firings of nerve endings.
Studies of VAHT
A pilot study co-conducted by this author has demonstrated the positive effects of VAHT on HRV.14 The study consisted of 10 subjects who received 15 minutes of VAHT, and all of whom reported some subjective decrease in pain/tension on a visual analog scale (VAS) at the end of the study. The average HRV was assessed and shown to improve in all patients. The actual VAHT session period yielded the greatest improvement in the subjects' heart rate entrainment compared to pre and post measures.14 It is theorized that the powerful vibratory effects of VAHT interrupt impulse transmission among pain pathways and other sensory channels, directing awareness inward. Based on this author's experience and feedback from patients, balancing of chi energy and stimulation of lymphatic flow can also result from VAHT. Some chronic pain conditions, such as complex regional pain syndrome (CRPS), are believed to be caused by internally generated, low-frequency oscillations and altered rhythms of information flowing between the thalamus and the cerebral cortex.15 The delivery of rhythmic entrainment and whole body vibration achieved with VAHT is capable of overriding the patient's "normal" sensory input and signaling using a higher amplitude and frequency, thereby establishing a new flow of information and symptom relief.
When the patient is relaxed, abstract thinking slows and awareness expands. VAHT often produces responses such as deep relaxation, dream-like imagery, pain and tension reduction, increased energy, perceptual changes, increased body awareness (beyond the constricting attention to pain), and feelings of being nurtured. Internal imagery often provides new awareness, positive reframing, and enhanced processing and integration of psychological material. The patient/therapist interaction allows for immediate responses in the course of the session (Table 1).
