Introduction: Trigger finger is a common, underdiagnosed finger aliment, thought to be caused by inflammation and subsequent narrowing of the A1 pulley, which causes pain, clicking, catching, and loss of motion of the affected finger in long standing diabetic patients. Till now steroid injections or surgical management has been a main stay for the treatment. Case presentation: We present the case of an otherwise physically-adept 58-year-old Diabetic Indian serviceman, with signs and symptoms consistent with volar flexor middle finger tenosynovitis (Trigger finger) in left hand. Range limitations in all motions of the left metacarpo-phalangeal joints complicated his presentation. Methods and Measures: Physical therapy included conventional intervention with superficial heat, ultrasound, stretching and transverse friction massage directed to the second volar flexor tendon. Conventional joint mobilization techniques addressed the motion limitations of the ii- iv metacarpophalangeal joints, radiocarpal, and midcarpal joints. In addition, INMAS technique was utilised at trigger site to promote pain-free wrist and finger mobility. Patient__ampersandsignlsquo;s sugar levels were closely monitored throughout the treatment. Results: The described treatment regime, which involved conventional physical therapy interventions, along with INMAS aided in the early complete resolution of this patient__ampersandsignlsquo;s impairments and functional limitations. Conclusion: The combination of conventional physical agents, exercise, and manual therapy, and the less conventional INMAS techniques, proved successful with this patient. INMAS involving needling of SA__ampersandsignlsquo;s which developed due to injury or disease. INMAS involving inoculation of minute trauma into the body to restore the mechanisms of self-healing was an effective and efficient adjunct to physical therapy intervention.
