Summary
Eccentric resistance training (ERT) shows no significant difference compared to traditional therapy for improving strength and movement in neurological conditions. ERT offers a viable alternative, allowing greater work volume with lower metabolic demand for these patients.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Exercise Physiology
Background:
- Neurological conditions often lead to muscle wasting, reduced strength, and impaired balance, hindering traditional weight training.
- Eccentric resistance training (ERT) presents an alternative for individuals unable to perform conventional full-range-of-motion exercises.
Approach:
- A systematic review and meta-analysis evaluated ERT's efficacy against traditional therapies for gait, balance, and strength in neurological disorders.
- Searches of Web of Science, PubMed, and Academic Search Complete were conducted, including a manual search, with data analyzed from 13 studies (n=297).
Key Points:
- The meta-analysis included 47 standardized mean differences (SMD) across studies measuring walking speed, Timed Up and Go (TUG), and maximum voluntary isometric contraction (MVIC).
- A small, non-significant effect was observed when comparing traditional therapies and ERT for performance outcomes (SMD: 0.136).
Conclusions:
- Eccentric resistance training (ERT) demonstrates comparable effectiveness to traditional therapy and weightlifting in improving movement outcomes for clinical populations.
- Practitioners can consider ERT as a supplement or replacement for traditional strengthening, as it enables higher work volumes at a lower metabolic cost.
