Effectiveness of aquatic versus land physiotherapy in the treatment of peripheral neuropathies: a randomized controlled trial.

objectiveTo compare the effects on gait and balance of aquatic physiotherapy versus on-land training, in the context of an inpatient rehabilitation treatment tailored for peripheral neuropathies.

designParallel-group, single-center, single-blind randomized controlled trial. SUBJECTS AND

settingConsecutive patients affected by peripheral neuropathy admitted in our Neuro-Rehabilitation Unit.

interventionsPatients received a four-week rehabilitation program composed by daily sessions of conventional physiotherapy and three sessions/week of specific treatment (aquatic vs. on-land). MAIN MEASURES: Primary outcome measures were Berg Balance Scale and Dynamic Gait Index. Secondary outcome measures were Neuropathic Pain Scale, Overall Neuropathy Limitations Scale, Functional Independence Measure, Functional Ambulation Classification, Conley Scale and Medical Research Council Scale score for the strength of hip and ankle flexor and extensor muscles. For each scale, we calculated the difference between the scores at discharge and admission and compared it between the two groups.

resultsForty patients were enrolled: 21 in the water-based rehabilitation group and 19 in the land-based one. Patients were similar between groups. When comparing the groups, we found that "in-water" patients had a significant better improvement in the Dynamic Gait Index score (6.00 (4.00, 7.25) vs. 4.00 (1.25, 6.00), P = 0.0433). On the opposite, the "on-land" group showed a better improvement of the Functional Ambulation Classification score (1.0 (0.75, 1.0) vs. 1.0 (1.0, 2.0), P = 0.0386).

conclusionAquatic physiotherapy showed an effect comparable to the land-based rehabilitation on gait and balance dysfunctions of neuropathic patients.
