Background: The index finger plays a major role in hand function. Subjects who sustain traumatic amputation of the single index finger also suffer both psychological and functional loss. Most of previous studies primarily focused on psychological benefits with finger prosthesis; however, it is essential to identify the functional benefit of the silicone finger in respective activity spectrum. Objectives: To determine the improvement in function and activities with silicone finger prosthesis in proximal phalanx index finger amputation. Materials and methods: Sixteen subjects were evaluated for the grip strength, pinch strength, and activities with dynamometer position II, pinchometer, and DASH questionnaire, respectively. Results: Significant improvement of grip strength revealed in dynamometer position II (p = 0.041) when tested without and with silicone finger prosthesis. The overall abilities in activities of daily living were improved significantly (p = 0.005) as assessed by disability of arm, shoulder and hand questionnaire. Large effect sizes were noted in some activities like writing, jar opening, and carrying heavy object. Conclusion: Silicone finger prosthesis provides a functional benefit to the subjects in multiple activities. Clinical relevance: Partial loss of a finger has a relationship in limitation of hand function. Generally, clinicians prescribe silicone prosthesis for rehabilitation of finger amputee to restore the cosmetic purpose; however, functionality of the finger is also required to be restored. This study describes the role of silicone finger prosthesis on function and different activities for the subjects suffering from the index finger proximal phalanx amputation.
