PainShield MD is an innovative treatment for pelvic and abdominal pain
including pain associated with the:
|  |
and pain associated with conditions such as:
|
|
Chronic Pelvic Pain is frequently associated with one or more of the above conditions (1,2) and may be relieved by therapies that help reduce muscle spasm (3-5). PainShield® MD uses this principle.In other work, PainShield
MD has been shown to alleviate the pain of trigeminal neuralgia and other
pain conditions.
In a clinical study (see below) involving 19 patients with severe chronic pelvic pain, interstitial cystitis or other conditions, PainShield MD significantly (p<0.05) reduced:
- pelvic pain
- bladder pain
- pain on urination
- pain on defecation
- related muscle or joint pain
Reductions in the frequency of painful urinary episodes, sacro-iliac joint pain, painful intercourse (dyspareunia), rectal pain, and pain resulting from prolonged sitting were also noted. Some patients reported a decrease in pain-associated sleep disturbance as well as reduced expenditures for pain and related medications (e.g. opioids). Patients rated their overall response as:
- Good (10/19)
- Moderate (3/19)
- Mild (4/19)
- Negative (2/19)

Methods: In this open−label, prospective, experiential study, 16 women and 3 men (age 46, range 33−62) with a history of chronic pelvic, urological or related pain or symptoms (15.3 years, range 1−33 years), received Painshield on prescription. Diagnoses included endometriosis (26%), adhesions (63%), bowel obstruction (42%), IBS (32%), Interstital Cystitis (32%) or other CPP (63%). Patients provided information about their symptoms before treatment and up to 51.4 days (range 1−207) afterwards. Scoring was based on the Brief Pain Inventory, Short−Form McGill Questionnaire, and the International Pelvic Pain Society’s form. Scores from before and after treatment were compared by t test comparison of rankings of levels (0−10) of each type of pain using the maximum score reported.
Results: Often exceeding or approaching statistical significance, improvements in pain or related symptoms were noted (before treatment score v. after treatment score, N, p) for all symptoms which were pain before urination (6.1 v. 4.3, N=12, p=0.021); pain on urination (6.0 v. 2.0, N=7, p=0.001); urinary urgency (% of time) (100% v. 54%, N=6, p=0.06); urination frequency/day (21 v. 14, N=11); difficulty urinating (% of time) (100% vs 60%, N=8, p=0.08); Other chronic pelvic or abdominal pain (8.3 vs 5.9, N=12, p=0.042); dyspareunia (during) (7.8 v. 5.5, N=12); dyspareunia (after) (6.6 v. 4.3, N=8); dyschezia (7.7 v. 3.6; N=10, p=0.001); abdominal bloating (% of time) (83% vs 53%, N=10, p=0.049); rectal pain (9.3 v. 6.0, N=4); sacroiliac joint pain (8.5 v. 6.5, N=6, p=0.081); sitting tolerance (minutes) (36 v. 91 mins, N=12); other muscle/joint pain (7.4 v. 5.2, N=18, p=0.03).
Patients often reported the onset of relief within hours or days after starting treatment and a reduced need for analgesic or other medication. Overall patients rated their response as Negative (2/19), Mild (4/19), Moderate (3/19) or Good (10/19). The two patients responding negatively reported a rapid onset (< 1 day) of pain and/or swelling which subsided from 1 to several days later. One patient responding well experienced some abdominal discomfort after using the device. Two of these patients reported similar reactions to conventional office−based ultrasound.
Conclusion: Further evaluation of the utility of Painshield in this patient population is warranted.
Summary: PainShield, a portable, wearable ultrasound device was found to reduce pelvic, urological pain and related symptoms in 19 patients presenting with long−standing and refractory symptoms.
