ABSTRACT
Objective To explore the characteristics of gait and surface electromyography (sEMG) of underwater treadmill training (UWTT). Methods From January to September, 2015, gait and sEMG parameters of ten healthy adults were synchronously collected using three-dimensional gait analysis system and sEMG systems on land and UWTT. Results When walking in self comfortable speed, compared with walk on land, there was significant increase in gait cycle (t=-11.411, P0.05). The integral electromyography of biceps femoris, gastrocnemius, tibialis anterior muscle were significant less than iEMG on land (t>3.984, P0.05). Conclusion There are signifi-cant differences in gait and muscle contraction intensity between land walking and UWTT. The dynamic physiology and neural control of UWTT need further study.
ABSTRACT
@#Objective To compare the effect of underwater treadmill training (UWTT), body weight support treadmill training (BWSTT) and conventional gait training (CGT) for walking ability and balance function in hemiplegic patients after stroke. Methods 43 patients were divided into CGT group (n=14), BWSTT group (n=13) and UWTT group (n=16). Based on conventional gait training, the UWTT group and BWSTT group respectively accepted UWTT and BWSTT for 4 weeks. They were assessed with Functional Ambulation Category (FAC), maximum walking speed (MWS), 6 Minute Walk Test (6MWT), and dynamic balance function and static balance function with Active Balancer before and after training. Results All the patients improved in all items after training (P<0.05), while the UWTT group improved more in the 6MWT and balance function items than the BWSTT group (P<0.05). Conclusion UWTT is more effective for hemiplegic patients after stroke in walking ability and balance function than BWSTT.

ABSTRACT
@# Objective To investigate the effect of underwater treadmill training (UWTT) on patients with hemiplegia after stroke. Methods Based on routine rehabilitation, 15 hemiplegic patients after stroke were treated with UWTT system 20 min/d, 5 times a week for 4 weeks. Walking distance and speed in water were tested before and after UWTT. Dynamic balance function and static balance function were also assessed by Active Balancer assessment. Results All the items improved significantly after treatment (P<0.01), except deflection center displacement of X and Y axis (P>0.05). Conclusion UWTT can improve the walking ability and balance function of hemiplegic patients after stroke.
ABSTRACT
@#Underwater treadmill training (UWTT) is a new hydrotherapy technique, with features of immersion bath, under water walking and body-weight support treadmill training. UWTT can reduce the load on legs, release spasm, improve gait, muscle atrophy and remain muscle strengthen for SCI patients. It also reduces the risk for cardiovascular disease, and incidence of postural hypotension. The present studies on UWTT are insufficient. More researches should further explore the therapeutic effects on SCI.
ABSTRACT
Objective To observe the efficacy of underwater partial body-weight-supported treadmill training in repairing spinal cord injury (SCI) and its relationship with spinal nerve plasticity. Methods A total of 40 Sprague-Dawley rats were randomly divided into five groups: a sham model group, a model control group, an underwater training group, a partial body-weight-supported treadmill training (PBWSTT) group and an underwater PBWSTT group. A rat model of SCI was induced by contusion of the T10 segment with a Multicenter Animal Spinal Cord Injury Study (MASCIS) impactor. One week post-operation, different rehabilitation strategies, such as free exercise in water, BWSTT and underwater PBWSTT, were administered to the rats in the underwater training groups for 8 weeks.Those in the sham model group and model control group were given no training. The Basso, Beattie and Bresnahan (BBB) locomotor rating scale and a climbing test were used to evaluate the recovery of hindlimb locomotor function.The expression of brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) in the spinal cords was detected with immunohistochemical methods. Results Nine weeks post-operation, hindlimb locomotor function had improved significantly more in the underwater PBWSTT group than in underwater training group or the BWSTT group.The expression of BDNF in the 3 training groups was significantly higher than in the model control group, though there was no significant difference among the 3 training groups. The expression of NT-3 in the underwater PBWSTT group increased more significantly than in the BWSTT group, however there was no significant difference between the underwater PBWSTT group and the underwater training group. Conclusion Underwater PBWSTT can promote the recovery of hindlimb locomotor function in rats after SCI, probably through increasing the expression of BDNF and NT-3 and thus promoting neural plasticity in the spinal cord.
