To evaluate the feasibility of jump training for nearly ambulatory patients after stroke.Design
A rehabilitation centre for adult people with neurological disorders.Subjects
Six subacute, nearly ambulatory patients with hemiparesis due to stroke.Interventions
A modified form of jump training performed over a period of six weeks.Measures
Impairments: We used the Motricity Index to measure strength, the Fugl-Meyer subtest passive joint motion/pain for range of motion and pain and the modified Tardieu Scale to measure spasticity at baseline and after six weeks. Activity level: To assess walking ability we used the Functional Ambulation Category, to measure walking quality we used 10-m gait velocity, stride length and Rivermead Visual Gait Index and to assess walking capacity we used the six-minute walk test.Results
No severe adverse events were observed during the study period. Motricity Index sum score of the affected leg increased from 38 ± 11 points (mean ± SD) to 56 ± 15 points; P = 0.028. Modified Tardieu Scale and Fugl-Meyer subtest passive joint motion/pain remained unchanged over time (P = 1.0; P = 0.157, respectively). All patients were able to walk at the end of training (median Functional Ambulation Category grade five, P = 0.023). Gait quality improved as shown in increased gait velocity (from 0.3 ± 0.1 to 1.1 ± 0.5 m/s; P = 0.028), improved stride length (from 0.3 ± 0.1 to 0.6 ± 0.2 m; P = 0.028) and improved Rivermead Visual Gait Index score (from 38.7 ± 5.6 points to 24.8 ± 7.0 points; P = 0.027). All patient increased gait capacity (from 97 ± 33 m to 289 ± 134 m; P = 0.028).Conclusion
Jump exercises are feasible for selected subacute stroke patients with hemiparesis.
