Summary
Late effects of polio significantly impair balance and gait velocity in survivors. This study highlights reduced postural control and its correlation with slower walking speeds, impacting daily activities and safety.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Gerontology
Background:
- Late sequelae of acute poliomyelitis can manifest as reduced balance and gait capacity years after the initial illness.
- Muscle weakness, fatigue, and pain are common factors contributing to mobility impairments in polio survivors.
- These mobility issues can significantly affect the daily activity levels of individuals with a history of polio.
Purpose of the Study:
- To characterize observer-assessed and self-perceived postural control in individuals with late effects of polio.
- To investigate the relationship between postural control and gait velocity in this specific population.
- To provide insights for improving daily life safety and mobility for polio survivors.
Main Methods:
- Fifty individuals diagnosed with polio and without other mobility disorders were included (mean age 59.8 years).
- Balance was assessed using the Timed Up and Go (TUG) test, Functional Reach (FR) test, and Falls Efficacy Scale (FES) (Swedish Version).
- Gait velocity was measured over 30 meters at both convenient and maximal speeds.
Main Results:
- Participants demonstrated reduced balance, with TUG mean of 9.0 seconds and FR mean of 23.5 cm.
- Self-reported balance problems in activities of daily living (ADL) were noted (FES(S) median 119.5 vs. normal 130).
- Gait velocity was significantly lower (convenient speed mean 1.01 m/s) compared to age-matched healthy individuals (1.30 m/s).
- Strong correlations were found between reduced balance and decreased gait velocity (TUG/gait velocity: r = -0.7 convenient, r = -0.8 maximal, p
Conclusions:
- Reduced balance and gait velocity are significant issues for individuals experiencing late effects of polio.
- Understanding these deficits is crucial for developing targeted interventions to enhance safety in daily activities, particularly gait.
- This knowledge can inform healthcare providers on optimizing support and services for this population.
