Discontinue any exercise that causes pain, weakness, or muscle fatigue, including walking. Muscles weakened by polio respond poorly to vigorous strengthening programs. Programs such as weight lifting often aggravate the condition. Each of you should know your own strength limits or endurance, and avoid going repeatedly to that limit. Occupational therapists can assess extremity function, daily activities, and the need for assistive devices to help achieve the highest level of independence possible.
Rest is the best known treatment for aching muscles.
Moist heat, anti-flammatory medication, and avoiding exertion are also helpful. Change of gait pattern, such as using crutches, may be needed to prevent recurrence of lower back pain. You MUST learn to conserve energy. Even though you were once rehabilitated, you must be re-evaluated and taught new techniques to replace those that no longer work. Body positioning during sleep is important for post-polios with severe weakness and postural joint deformities.
