Project MUbility aims to empower differently-abled Filipinos, from as many walks of life possible, and to highlight their capabilities that most people would mistakenly surmise these members of our society cannot cultivate. It also seeks to advocate for socio-economic, medical, and institutional changes which emphasize and improve their access to better care and the observance of their rights as our fellows. MUbility projects under this banner have, and will continue to do so, by raising public awareness of their existence, their diversity, and the significant challenges they face on a day-to-day basis. This advocacy has demonstrated its deeds by addressing multiple aspects relevant to both the campaign and the actual beneficiaries themselves.

As doctors and future doctors of medicine, the Brothers of the Mu Sigma Phi have sworn to serve the needs of our fellow people. MUbility was conceptualized due to problems observed by Dr. Josephine Robredo-Bundoc and Dr. Rafael Felipe Bundoc MΣΦ 1986, in the newly renovated Department of Rehabilitation Medicine of the Philippine General Hospital (PGH). Even with the available services offered for assistive devices, patients with amputations still chose to remain in their homes and resign to less productive lives. Answering to the call of service, the Brothers of the Mu Sigma Phi Fraternity partnered with PGH and the Physicians for Peace to form the MUbility Support Group in 2005, which advocated for the differently-abled to empower themselves and to reintegrate into society. The Brothers pooled financial and technological resources, constructed over 300 wheelchairs and 1,700 prostheses, distributed these to amputees all over the country, and helped in the education about the proper use of these assistive devices. Project MUbility, later on pursued the construction of the PGH Walking Assistance and Learning Key (WALK) Unit and inspire the National Prosthesis Walk-a-thon in 2009, PaligSamahan in 2013, Obra X and Reverb: The Concert in 2015, and the three Amputee Climbs held in 2009, 2013 and 2016.

Directly catering to their need for improved freedom of movement across their physical environs was achieved during the very first activity of the advocacy – the MUbility Support Group – by setting up amputees and other mobility-challenged Filipinos to rehabilitative care and provision of prosthetic units and wheelchairs. Highlighting their athleticism and clamoring for greater government support of their sportsmanship (through the enactment of the Senate Bill 3313 or the National Athletes, Coaches and Trainers Benefits and Incentives Bill) were the goals of PaligSamahan. Reverb: The Concert showcased the acumen and flair of differently-abled Filipinos, both young and old, for the performing arts. Obra X exhibited the artistic prowess of our fellows who mastered the art of painting masterpieces, even when seemingly hampered by their physical misfortunes, for instance, through their mouths and feet. Finally, in the grandest of hurdles set to almost impossible, amputees, together with the Brothers of the Mu Sigma Phi have proven thrice that no lack of extremities can stop one from reaching mountain peaks through  the Amputee Climbs in 2009 (Mt. Batulao, Batangas), 2012 (Mt. Pulag, Benguet), and, most recently, in April 2016 (Tarak Ridge, Batangas).
