Abstract: Background:Physical capacity (PC) and quality of life (QoL) are both reduced in multiple sclerosis (MS). Objective:Aim of our study was to investigate limitations in PC and QoL in response to the severity of MS. Methods:The study involved 60 patients (PG) (Expanded Disability Status Scale EDSS 0–3:38, EDSS 3.5–6:22) and 48 healthy controls (CG). Endurance capacity was assessed as peak oxygen uptake (VO2peak) and ventilatory anaerobic threshold (VAT). Maximum force was measured in isokinetic testing. QoL was assessed using the SF-36-questionnaire and HALEMS. Results:Patients with MS showed reduced VO2peak and QoL in comparison with CG. Patients with an EDSS >3 showed reduced VO2peak, and maximum force, however at the VAT there was no significant difference independent of the EDSS. The MS-specific QoL HALEMS and subscales 1, 4, 6, 8 and the physical sum score of the SF-36-questionnaire were evaluated to be better in patients with an EDSS ≤3. Conclusions:There are limitations within PC in patients with MS in comparison with a healthy CG; within the PG there are notes on a similar aerobic capacity but worsened anaerobic capacity in patients with an EDSS >3. This should be taken into account in future treatment strategies for training therapy.
