A prosthetist is a healthcare professional trained in creating customized prosthetic limbs for individuals with amputations or congenital limb deficiencies. They carefully evaluate patients' needs, take measurements, and design prostheses that provide comfort, function, and mobility. Prosthetists also educate patients on how to use and maintain their prosthetic devices.

Orthotists specialize in designing and fitting orthotic devices, which provide support, stability, and correction to different body parts. They work with patients suffering from musculoskeletal conditions, spinal deformities, and neurological disorders. Orthotists assess patients, determine the appropriate type of orthotics required, and create custom-made braces, supports, or splints to enhance mobility and alleviate pain.

A prosthetist-orthotist is a dual-trained professional who possesses expertise in both prosthetics and orthotics. They assess patients' needs, fabricate and fit prosthetic and orthotic devices accordingly. This combined knowledge allows them to address a wider range of rehabilitation needs, working with patients who require both prostheses and orthotic devices.

Rehabilitation engineers work alongside prosthetists and orthotists to develop innovative and technologically advanced assistive devices. They focus on designing, researching, and improving prosthetic and orthotic tools using engineering principles and techniques. Rehabilitation engineers collaborate with healthcare providers, industry professionals, and patients to enhance the functionality and effectiveness of these devices.

Physical and occupational therapists play a crucial role in the field of prosthetics and orthotics. They work closely with prosthetists and orthotists to help patients adjust to and effectively use their devices. These therapists guide individuals through rehabilitation exercises, teach them how to regain strength and mobility and devise strategies to improve their quality of life.

Research scientists and academics contribute to the field of prosthetics and orthotics through their research, innovation, and education. They conduct studies, develop new technologies, explore novel materials, and improve existing methodologies. They also teach aspiring students about prosthetics and orthotics, advancing knowledge and inspiring future professionals.
