Abstract

Background: Urinary incontinence (UI) is very common, affecting 421 million women and men worldwide. There are three types of UI: stress, urge and mixed. UI is associated with poor quality of life. There are numerous non-surgical treatments available. This paper reviews the mechanisms and clinical evidence for mechanotherapy gleaned from peer-reviewed literature. Mechanisms: The human body responds to various forms mechanical stimuli that direct cellular tissue forces, resulting in molecular responses that facilitate growth, remodeling and repair. Mechanotransduction is the basis for mechanotherapy, characterized by complex chemical signaling and neural signaling. Two modalities of mechanotherapy have been investigated in published studies. Mechanical Vibration: Vibration caused by oscillatory motion stimulates stretch sensitive mechanoreceptors in the pelvic floor muscle (PFM) spindles, resulting in afferent nerve impulses to the sacral plexus and centers in the brain. Resulting efferent signals cause motor unit activation. Types of vibration delivery include intra-vaginal, whole-body, and local transcutaneous. Acoustical Wave Stimulation: Acoustic energy generated by piezoelectric crystals modify molecules as the waves are transmitted from one molecule to another. This type of mechanotherapy includes four stages: propagation, physical effect, mechanotransduction and biological effect. Most published research studies utilized low intensity extracorporeal shock waves (LiESWT) in their protocols. Conclusion: Mechanotherapy provides powerful physiologic stimulation that has been shown in many studies to improve clinical symptoms of UI and improve QoL. It is a promising, emerging, non-invasive option for inclusion in the clinical armamentarium for treating patients with all forms of UI.

Introduction

Continence and urination are the result of coordination of smooth and striated muscles of the lower urinary tract and pelvic floor that occurs with regulation between the central and peripheral nervous system; it involves multiple levels both voluntary and involuntary control as explained below. Urinary incontinence (UI) is the involuntary loss of urine, more commonly observed in women. There are three main types of UI: (1) stress urinary incontinence (SUI), characterized as the sudden involuntary loss of urine during activities such as coughing, sneezing, exercise and bending/lifting; (2) urgency urinary incontinence (UUI) is distinguished by an involuntary loss of urine with a sudden, uncontrollable urge of needing to urinate; and (3) mixed urinary incontinence (MUI) which includes features of both SUI and UUI [1]. Urinary incontinence is strongly associated with poor quality of life (QoL) as shown in many peer-reviewed publications that used multiple, validated questionnaires. These studies reported decreases in various domains of QoL (e.g., physical wellbeing, psychological and emotional health, social relations, etc [2,3,4,5,6]. UI is also associated with social withdrawal, depression, earlier retirement and loss of independent living in older patients [7]. Women reporting MUI symptoms describe more severe and bothersome incontinence and poorer QoL [6]. Given the high negative impact on QoL, the burden of urinary incontinence not surprisingly has a high global prevalence, despite likely being underdiagnosed. As of 2018, the global prevalence of UI was approximately 421 million [10]. For adult women in the United States, 61.8% (78,297,094 ) had UI, partitioned as SUI 22.0%, UUI 22.0%, MUI 31.3%, Unspecified 9.2%) [11]. Risk factors for UI include parity, obesity, chronic cough, depression, poor health, lower urinary tract symptoms, previous hysterectomy, and stroke; UI is more common in the elderly, but affects women of all ages [8,9,11]. Women with SUI typically delay seeking medical help for over a decade; this longer duration is associated with increased severity and greater need for continence pads [12].
Numerous non-surgical treatments are available to address UI, including pelvic floor muscle training, behavioral therapy, bladder training, caffeine avoidance and weight loss; pharmacological therapies are used in UUI [13,14]. Among these, mechanotherapy has emerged as a promising clinical approach, either as sole treatment or as an adjunct to other therapies. This paper discusses the mechanisms of action and clinical evidence of various forms of mechanotherapy gleaned from the peer-reviewed literature.

Mechanisms of Action

The human body responds to mechanical stimuli such as vibration, touch, stretch, and pressure via mechanoreceptors. Mechanoreceptor sensor cells detect changes in their environment and respond rapidly to the mechanical stimuli interacting with them. As illustrated in Figure 1, mechanical stimuli direct cellular activities to induce tissue adaptation. These mechanical forces initiate a chain response involving tissue level forces and cellular forces that result in molecular responses, that in turn create a feedback loop via the extracellular matrix (ECM) [13]. This process facilitates tissue-level adaptations including growth, remodeling, and repair that alters tissue mass, structure, and quality [15].
Tensegrity, or “tensional integrity,” is a structural principle where stability is maintained by a balance between continuous tension (muscles / fascia) and discontinuous compression (bones / extracellular matrix) [16]. For example, cells and tissues can respond rapidly to mechanical stresses transmitted over cell surfaces via connections that physically couple the cytoskeleton of cells to the extracellular matrix, as well as other cells [16].
Cells and tissues are under physiological tension even in the absence of external loading through the self-stabilizing system of tensegrity. As such, tensegrity is the basis for cells’ ability to respond immediately to mechanical stresses transmitted across cell receptors that physically couple the cytoskeleton to the extracellular matrix [16].
Mechanotransduction
Mechanotherapy is the intentional clinical triggering of mechanotransduction.
Mechanotransduction is the basis for mechanotherapy. It is the molecular mechanism by which cells sense and convert mechanical signals into cellular response to a variety of mechanical stresses [17]. Mechanotransduction requires a mechanical signal to be transmitted to tissues and cells. This process may be altered by changes in cell mechanics, variations in the extracellular matrix, or by deregulation of the molecular mechanisms by which cells sense mechanical signals and convert them into chemical or electrical responses [18]. Mechanotransduction is mediated by extracellular matrix molecules, transmembrane integrin receptors, cytoskeletal structures and associated signaling molecules, all of which are potential targets for therapeutic applications [16]. Mechanical loads are transmitted across structural elements that are physically interconnected. Mechanotransduction is controlled by both complex chemical and neural signaling pathways, as discussed below.
Chemical Signaling
Once a cell has detected a local mechanical stimulus, the cell converts the stimulus into a biochemical response known as biochemical coupling. Multiple signaling pathways are used by the cell to initiate a biochemical signaling response. As illustrated in Figure 2, musculoskeletal cells sense incoming mechanical signals using a diverse group of transmembrane mechanosensitive proteins (mechanosensors), including stretch activated
ion channels, cell-membrane spanning G-protein-coupled receptors, growth-factor
receptors, and integrins [15]. In response, muscle cells convert the mechanical signals into biochemical signals (‘biochemical coupling’) that triggers a cascade of multifarious intracellular pathways culminating in activation of transcription factors and induction of mechanosensitive genes [15].
Neural Signaling and Modulation
Broadly speaking, the nervous system is composed of two parts. The Central Nervous System (CNS), that includes the brain and the spinal cord, and the Peripheral Nervous System (PNS), that involves neural structure outside of the CNS. The PNS is composed two divisions: (1) a somatic portion that controls voluntary responses and (2) the autonomic portion that controls involuntary responses [19]. Normally, these portions of the nervous system operate in equilibrium. Mechanotherapy engages the autonomic portion of the PNS.
In addition to the cellular mechanisms described above, mechanotherapy also modulates nerve signaling via the stimulation of mechanoreceptors located in muscles, tendons and ligaments that activate the proprioceptive sensory system within the PNS [20]. This nerve signaling enhances afferent and efferent neural communication involving somatic peripheral nerves, the sympathetic and parasympathetic reflexive spinal sacral plexus pathways, and the higher conscious control centers of the brain (Figure 3) [21]. The cumulative effect of improved neuromuscular facilitation and motor learning is development and retention of muscle memory [22,23]

Clinical Evidence

Several modes of mechanotherapy have been used to treat urinary incontinence, either as sole therapy or as adjuncts to other treatments. These include several types of vibration and approaches using shockwave / acoustical energy.
MECHANICAL VIBRATION
Vibration is a mechanical stimulus characterized by an oscillatory motion. The biomechanical variables that determine its intensity are the frequency and amplitude. The extent of the oscillatory motion determines the amplitude (peak to peak displacement, in mm) of the vibration. The repetition rate of the cycles of oscillation determines the frequency of the vibration (measured in Hz) [24]. Vibration stimulates specific mechanoreceptors in muscle spindles in the pelvic floor that are sensitive to stretching. This stimulation triggers an involuntary muscle contraction known as the tonic vibration reflex (TVR) [24,30].
Muscle–tendon vibration generates a strong proprioceptive inflow, primarily driven by Ia afferent nerve fibers, but also involving group II, Ib and cutaneous afferents [25]. These afferent impulses travel through spinal sacral neurons to thalamus and cortical structures in the brain. Resultant efferent signals cause motor unit activation, leading to increased motor unit recruitment of previously inactive muscle fibers [25]. Sub-contractile vibratory stimulation may enhance voluntary muscle contraction using the same neural pathways [26].

Intravaginal Mechanical Vibration

Application of intravaginal vibration provides direct mechano-stimulation of the pelvic floor muscles (PFM). The authors are aware of only one commercial device that provides intravaginal mechanotherapy.
The Flyte® System by Pelvital provides two-step transvaginal mechanotherapy: 1) pre-stretch / pre-loading of the PFM; 2) the superimposition of mechanical pulses at a very specific, low frequency tuned to the PFM, that are superimposed on voluntarily contracted and relaxed PFM (Kegel exercises). The system consists of an intravaginal wand and control unit (Figure 4). At-home treatment sessions are five minutes a day, for a standard treatment protocol of six weeks. It is the only home-based transvaginal mechanotherapy treatment known to the authors.
Flyte System’s intravaginal mechanotherapy has been shown in two published clinical trials in women with stress urinary incontinence with outcomes comparable to surgical outcomes [19]. A study at Arctic University in Norway assessed this mechanotherapy treatment in 60 women with Stress Urinary Incontinence (SUI), characterized as between 5-50g of leakage on the 1-hour stress test, and who had been referred for surgery after having failed supervised PFMT. The study found 44 (73.3%) and 49 (81.7%) of women were defined as continent after 4 and 6 weeks of treatment, respectively. All participants who completed the 2-year follow up interviews had not undergone surgery for SUI since the mechanotherapy treatment, with 77.0% reporting continued continence [27].
Nakib and co-authors studied the Flyte System’s intravaginal mechanotherapy treatment in 119 women with mild (10-20 g of leakage), moderate (21-70 g of leakage), and severe SUI (>70 g of leakage), with a range of 10.3g to 533.9 g, as measured by the 24-hour pad weight test. The researchers found that the use of mechanical stimulation superimposed on Kegel contractions improved SUI in as little as two weeks (37%), with 80% having responded to treatment in 6 weeks, and 91% in 12 weeks. Using the 24-hour pad weight test, 71% (81/119) of subjects were substantially improved or continent (defined as <10g) within 12 weeks (p=<0.001), with a median pad weight at 12 weeks of 5.3 grams. In addition, Quality of Life (QoL) using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) also showed highly significant improvements (p=<0.001) in all severity groups (Figure 4) [28].

Rodriques, et al., reported results from a randomized clinical trial comparing intravaginal vibratory (IVVS) versus intravaginal electrical stimulation (IEVS ) in women who were unable to contract their PFM, 19% of which had incontinence at baseline. Both devices were custom made with adjustable intensity output (and neither study device is commercially available). Treatment consisted of six 20- minute sessions held once a week. PFM evaluation consisted of bidigital vaginal palpation and the first four items of the New PERFECT scale: P (power), E (endurance), R (repetitions), and F (fast contractions). Measures of PFM performance were made by the Modified Oxford Scale (graded from 0 to 5). Power measures PFM strength by the Modified Oxford Scale (graded from 0 to 5). Endurance measures the duration of a maximum voluntary contraction until its strength is reduced by 50% or more. Repetitions assess the number of repetitions of the previous contraction, and Fast assesses the number of fast contractions performed in 10s. While both groups were noted to have improvements at the end of treatment, PFM contraction strength in the IVVS group improved significantly more than the IVES group (p = 0.026). The authors conclude that “IVVS was significantly superior to IVES in improving pelvic floor muscle strength, is easier to use, may be done at home, and is less uncomfortable.” [29]

Whole Body Vibration

Numerous articles have demonstrated that whole body vibration (WBV) successfully activates the pelvic floor muscles of their subjects, including those with weakened pelvic floor muscles [31,32,33]. WBV devices currently available on the market deliver vibration to the whole body by means of oscillating plates using two different systems: (a) reciprocating vertical displacements on the left and right side of a fulcrum; (b) the whole plate oscillating uniformly up and down [24]. WBV indirectly stimulates the PFM, typically utilizing commercially available vibration plates. It has been reported that WBV: (1) improves the PFMs strength and QOL in individuals with urinary incontinence; (2) does not cause (PFM) fatigue in nulliparous continent women; (3) leads to higher (PFM) activation in subjects with weakened (PFM) and (4) achieves higher pelvic floor (PF) activation than maximum voluntary contraction alone [34]. Several studies have demonstrated the efficacy of WBV for improving UI symptoms, as summarized below.
Farzinmehr and colleagues conducted a randomized study in 43 women with SUI that compared WBV training (Power Plate, USA) and PFMT three time per week over four weeks. Muscle strength was assessed based on the Modified Oxford Scale by digital palpation by a physical therapist trained in pelvic floor muscle examination. Severity of incontinence was appraised using a visual analog scale (VAS) from zero to ten. Quality of life was evaluated using the incontinence quality of life (I-QOL) questionnaire. At the end of treatment both groups experienced significant improvement in all three metrics (p=0.0001) that were sustained at three months. However, there were no difference between groups [35].
Tantaway and co-authors evaluated the effects of WBV in a randomized trial of male patients post-surgical prostatectomy with SUI. Group 1 included 30 patients who performed pelvic floor muscle training and whole-body vibration training; Group 2 included 31 patients who performed pelvic floor muscle training alone. The interventions in both groups were conducted three times per week for 4 weeks. I-VAS score, ICIQ-UI-SF score, and 24-hour Pad test result all showed significant differences at each assessment (p=0.001) in both groups. However, compared to Group 2, significantly greater benefits were noted in Group 1 in all measured parameters at 4 weeks and at all subsequent follow-up periods [36].

Local Transcutaneous Vibration

Cutaneous mechanoreceptors include Merkel disks and Meissner corpuscles located in the superficial layers and Pacinian corpuscles found in deeper layers of the skin and fascia between the muscles and periosteum. Merkel disks respond to low vibratory frequencies (5 – 15 Hz), Meissner corpuscles to medium frequencies (20-50 Hz) and Pacinian corpuscles to high frequencies (60-400 Hz) [37].
A few studies evaluated the efficacy of local transcutaneous vibration on urinary incontinence. Sonksen, et al., assessed the efficacy of perineal transcutaneous mechanical nerve stimulation (TMNS) in 33 women with SUI using the commercially available FERTI CARE® therapeutic device (Figure 6). All subjects had tried other treatments including pelvic floor muscle training (100%), behavioral intervention (100%) and peripheral electrical stimulation (3 patients), which had failed. Perineal TMNS was performed weekly by placing the device on the center of the perineum for 10 seconds followed by a pause of 10 seconds, for a total of 10 cycles per session. Subjects were instructed to perform standard PFMT after completing the TMNS program. After 6 weeks of TMNS, a statistically significant reduction (p=<0.001) was found in the number of incontinence episodes and the number of pads used as recorded in the voiding diary. Of the 33 subjects, 24 (73%) were cured and 29 (88%) were cured or the condition improved. The benefits remained at three months in the majority of women [38].

Fode and associates examined the effects of penile vibratory stimulation (PVS) also using the FERTI CARE® vibration device in the treatment of post-prostatectomy urinary incontinence during a 12 week trial in 31 men. A 24-hr pad test and a 72-hr voiding diary were collected at baseline. Participants were then randomized to receive PVS for the first 6 weeks (Group 1) or for the full 12 weeks (Group 2). The difference in the change on the pad test between the groups did not reach statistical significance at 6 weeks (p=0.13), whereas the number of incontinence episodes between groups approached statistical significance (p =0.052). However, there was a median reduction of 33 g (p =0.021) on the pad test and a median reduction in daily incontinence episodes by one (p =0.023) in group 1 at 6 weeks. At 12 weeks, group 2 had a median decrease on the 24-hr pad test of 8 g (p=0.10) and no change in incontinence episodes. A pooled analysis showed a reduction in pad test of 13.5 g (p=0.004) after PVS. Of the patients who completed PVS treatment, 60% were either very satisfied or partly satisfied (60%). Side effects were observed in 15% of men, most frequently reported as discomfort, with one case of mild bleeding on the glans of the penis. Two patients experienced stimulation pain that caused them to withdraw from the study. Five patients voluntarily reported improvement in erectile function [39].
ACOUSTICAL WAVE STIMULATION
Another form of PFM stimulation utilizes acoustic energy, typically generated using piezoelectric crystals, that interacts with body tissues [40]. The acoustic energy moves through the tissue in longitudinal waves according to the frequency and amplitude of the waves. This energy slightly modifies molecules and passes from one molecule to another. Molecules along the transmission wave oscillate in the same direction of the wave [40]. As illustrated in Figure 5, the mechanisms for acoustical therapy have been postulated to include four stages: propagation, physical effect, mechanotransduction, and biological effect [43]. Depth of energy penetration is inversely proportional to frequency. Lower frequencies produce lower resolution and greater depth in the body [40]. in addition, there is evidence that the physical properties of the wave form can be optimized based on the type of urinary incontinence, with low frequencies (10–20 Hz) for urge incontinence and higher frequencies (50 Hz) for stress incontinence [41,42]. Most published UI research studies utilize low intensity extracorporeal shock waves (LiESWT) in their protocols.
Long and colleagues evaluated the efficacy of LiESWT in 50 women with SUI, assessed at baseline, four weeks, eight weeks and one month. Involuntary urine leakage was assessed by the pad test (type unspecified), which demonstrated significant reductions at all follow-up periods (p < 0.01). In addition, quality of life was assessed using the OABSS, ICIQ-SF, UDI-6 and the IIQ-7 validated questionnaires. All questionnaires demonstrated significant improvement at all follow-up times, as shown in Figure 7. Of note, while the study population consisted of women with SUI, significant improvements in OAB symptoms were also exhibited [44].
Lin and co-authors performed a multicenter, single-blind, sham-controlled, randomized trial that assessed LiESWT in 60 women with SUI. Treatment was provided once weekly for four and eight week periods. LiESWT significantly decreased urine leakage from 7.93±1.32 at baseline to 2.43±0.40 g (p < 0.001) at four weeks that was sustained through six months. In addition, 64.4% of participants had moderate to better improvement (>50%) after 4 weeks of LiESWT, with the proportion of improvement increasing to 68.8%, 77.8%, 82.3%, and 84.5% at week eight, one, three and six months. The 3-day urinary diary revealed that eight weeks of LiESWT significantly improved OAB symptoms in these SUI participants. In addition, four weeks of active treatment significantly improved all questionnaire scores (ICIQ-SF (p = 0.034), UDI-6 (p = 0.040), and IIQ-7 (p = 0.048) compared to the sham group; the OABSS change was not significant (p = 0.520) [45].
Barassi, et al., investigated whether an integrated rehabilitation protocol including neuromuscular manual therapy and focused mechanical acoustic therapy targeting superficial PFM can significantly reduce pelvic floor dysfunctions in 62 women affected by stress, urge, or mixed urinary incontinence. Treatments were performed twice a week for four weeks. Mechanical characteristics (muscle tone, rigidity, muscle plasticity) of the PFM were measured using the MyotonPRO® handheld device (Figure 8). All evaluated parameters demonstrated significant improvement (p=<0.001). In addition, significant improvements were noted in PFDI-20 and PFIQ-7 questionnaire results showed a significant reduction of scores (p=<0.001) [46].
Lu and co-authors examined the therapeutic effect and duration of low intensity LiESWT on overactive bladder (OAB) symptoms in a prospective, randomized, single-blind clinical trial in 65 patients. Subjects were randomly divided into active LiESWT once a week for eight weeks, or identical sham LiESWT without energy transmission. Subject were followed for 4, 8 weeks and one, three and six months. Compared to baseline there was no meaningful difference in the daytime frequency (p = 0.77), nocturia (p = 0.12) and urgency (p = 0.50) after 4 weeks of treatment in the sham group. However, in the active LiESWT group, LiESWT meaningfully decreased daytime frequency (p < 0.01), nocturia (p < 0.01) and urgency symptoms (p < 0.05 ) as illustrated in Figure 9. Uroflowmetry measurements, including voided urine volume, Qmax and PVR were noticeably improved in the active treatment group compared to the sham group. Active LiESWT patients demonstrated significantly (p<0.01) improved OABSS, UDI-6 and IIQ-7, and the ICIQ-SF (p < 0.05) compared to no meaningful change in the sham group [47].
In a retrospective, observational case-controlled study, Paolucci and associates assessed the effects of focal LiESWT in 65 patients with MUI. Subjects were randomized to active therapy using the Vibration Sound System® for four weeks versus no therapy; both groups received home-based postural ergonomic instructions to reinforce the pelvic floor. PFM muscle parameters were evaluated using the MyotonPRO® device. The treatment group demonstrated significant improvement (p=<0.05, p=<0.001) in all muscle indices. Improvement in incontinence symptoms and quality of life as evaluated with PDFI-20 (p=<0.001) and PFIQ-7(p=<0.00) scores were noted [48].
Lee, et al., assessed the therapeutic effects of LiESWT on OAB applied to the suprapubic area using a commercially available instrument (DUOLITH SD1 T-TOP, AG) in 82 women assessed at baseline, four and eight weeks, one month and three months. As demonstrated in Figure 10, significant improvements were observed in Quality of Life using multiple questionnaires (ICIQ-SF, UDI-6 and IIQ-7), as well as OAB symptoms (OABSS). In addition, the 3-day diary showed increases in bladder capacity, daytime frequency (p=<0.01), nocturia (p=<0.01), and urgency (p=<0.05, p=<0.01) at the follow-up timepoints. Furthermore, uroflowmetry was noted to improve voided urine volume (p=<0.05), maximum flow rate (p=<0.05) and post-void residual volume (p=<0.05) [49].

Discussion and Conclusion

Urinary incontinence affects a large number of both women and men. It is estimated that one in seven adult women will undergo surgery for SUI during their lifetime [50]. Healthcare practitioners need to include assessment for UI into their practices, particularly in patients with elevated risk factors. Early detection and treatment of UI can enhance the quality of life and lessen the impact of associated comorbidities [51].
Early detection and treatment of UI can enhance the quality of life and lessen the impact of associated comorbidities, such as recurring UTIs or social isolation brought on by shame.
To reduce the need for surgery, additional and more effective non-invasive therapies, especially those that are home based and easy to access, are needed. Mechanotherapy provides powerful physiologic stimulation that has been shown by many studies to improve clinical symptoms of UI and improve QoL, as summarized in this paper. Mechanotherapy can be used as a stand-alone treatment, or be used as an adjunct with other therapies, e.g., pelvic floor muscle training. It is a promising, emerging non-invasive option for inclusion in the clinical armamentarium for treating patients with all forms of UI.
