Is treadmill walking with body weight support during inpatient rehabilitation detrimental to walking quality compared with assisted overground walking? Does it result in better walking capacity, perception of walking or community participation?
                Analysis of secondary outcomes of a randomised trial with concealed allocation, assessor blinding and intention-to-treat analysis.
                126 patients unable to walk within 4 weeks of a stroke who were undergoing inpatient rehabilitation.
                The experimental group undertook up to 30 minutes of treadmill walking with body weight support via an overhead harness per day while the control group undertook up to 30 minutes of overground walking.
                The secondary outcomes were walking quality and capacity, walking perception, community participation and falls.
                Six months after entering the study, there was no difference between the groups of independent walkers in terms of speed (MD 0.10 m/s, 95% CI -0.06 to 0.26) or stride (MD 6 cm, 95% CI -7 to 19). The independent walkers in the experimental group walked 57 m further (95% CI 1 to 113) in the 6 min walk than those in the control group. The experimental group (walkers and non-walkers) rated their walking 1 point out of 10 (95% CI 0.1 to 1.9) higher than the control group. There was no difference between the groups in community participation or number of falls.
                Treadmill training with body weight support results in better walking capacity and perception of walking compared to overground walking without deleterious effects on walking quality. To test whether body weight-supported treadmill training (BWSTT) is effective in improving functional outcome of patients with Parkinson's disease.
                Prospective crossover trial. Patients were randomized to receive either a 4-week program of BWSTT with up to 20% of their body weight supported followed by 4 weeks of conventional physical therapy (PT), or the same treatments in the opposite order. Medications for parkinsonism were not modified throughout the study.
                Inpatient rehabilitation unit for neurologic diseases.
                Ten patients (5 men, 5 women) with Hoehn and Yahr stage 2.5 or 3 parkinsonism; mean age 67.6 years, mean duration of Parkinson's disease 4.2 years.
                The Unified Parkinson's Disease Rating Scale (UPDRS), ambulation endurance and speed (sec/10 m), and number of steps for 10-meter walk.
                The mean total UPDRS before/after BWSTT was 31.6/25.6, and before/after PT was 29.1/28.0. Analysis of covariance for improvement of UPDRS demonstrated a significant effect of type of therapy (F(1, 16) = 42.779, p < .0001) but not order of therapy (F(1, 16) = 0.157, p = .697 1). Patients also had significantly greater improvement with BWSTT than with PT in ambulation speed (BWSTT, before/after = 10.0/8.3; PT, 9.5/8.9), and number of steps (BWSTT, 22.3/19.6; PT, 21.5/20.8).
                In persons with Parkinson's disease, treadmill training with body weight support produces greater improvement in activities of daily living, motor performance, and ambulation than does physical therapy. To determine the effects of a perturbed walking exercise using a bilateral separated treadmill in physically disabled elderly.
                Participants of the study were 32 long-term care facility residents and outpatients aged 66-98 yrs. Participants were randomly assigned to a usual exercise group or to a treadmill exercise group. Perturbed gait exercise on a treadmill continued for 6 mos. Number of falls and time to first fall during a 6-mo period, balance and gait functions, and reaction time were evaluated before and after intervention.
                The treadmill exercise group showed significant improvement in balance and reaction time when compared with the usual exercise group. Number of falls in the treadmill exercise group was 21% lower than that in the usual exercise group. However, this difference was not significant. No significant differences were seen in time to first fall.
                Gait training with unexpected perturbation seems to have a beneficial impact on physical function in disabled elderly individuals. The results suggest that this program may be used as an exercise intervention to reduce falls in institutional settings. In patients with intermittent claudication, a supervised walking exercise program increases peak exercise performance and community-based functional status. Patients with peripheral arterial disease also have muscle weakness in the affected extremity that may contribute to the walking impairment. However, the potential benefits of training modalities other than walking exercise, such as strength training, have not been critically evaluated in this patient population. The present study tested the hypothesis that a strength training program would be as effective as treadmill walking exercise and that combinations of strengthening and walking exercise would be more effective than either alone in improving exercise performance.
                Twenty-nine patients with disabling claudication were randomized to 12 weeks of supervised walking exercise on a treadmill (3 h/wk at a work intensity sufficient to produce claudication), strength training (3 h/wk of resistive training of five muscle groups of each leg), or a nonexercising control group. Graded treadmill testing was performed to maximally tolerated claudication pain to define changes in peak exercise performance. After 12 weeks, patients in the treadmill training program had a 74 +/- 58% increase in peak walking time as well as improvements in peak oxygen consumption (VO2) and the onset of claudication pain. Patients in the strength-trained group had a 36 +/- 48% increase in peak walking time but no change in peak VO2 or claudication onset time. Control subjects had no changes in any of these measures over the 12-week period. After the first 12 weeks, patients in the initial walking exercise group continued for 12 more weeks of supervised treadmill training. This resulted in an additional 49 +/- 53% increase in peak walking time (total of 128 +/- 99% increase over the 24 weeks). After the initial 12 weeks, patients in the strength-trained group began 12 weeks of supervised treadmill training, and patients in the control group participated in a 12-week combined program of strengthening and treadmill walking exercise. The combined strength and treadmill training program and treadmill training after 12 weeks of strength training resulted in increases in peak exercise performance similar to those observed with 12 weeks of treadmill training alone.
                A supervised treadmill walking exercise program is an effective means to improve exercise performance in patients with intermittent claudication, with continued improvement over 24 weeks of training. In contrast, 12 weeks of strength training was less effective than 12 weeks of supervised treadmill walking exercise. Finally, strength training, whether sequential or concomitant, did not augment the response to a walking exercise program. To study the application of partial weight-bearing (PWB) supported treadmill gait training augmented by functional electric stimulation (FES) in subjects with acute incomplete spinal cord injury (SCI).
                Before-after crossover trial with control (A) and intervention (B) periods.
                Physiotherapy (PT) department of a spinal injuries unit in Scotland.
                Fourteen inpatients with acute incomplete SCI with American Spinal Injury Association class C or D injury.
                Training consisted of treadmill walking with PWB support augmented by FES. Subjects walked on the treadmill for up to 25 minutes a day, 5 days a week for 4 weeks. The intervention was compared with a 4-week control period in which standard PT was given.
                Overground walking endurance and speed, cadence, stride length, and observational gait analysis and walking speed, distance, and percentage PWB support on the treadmill.
                A greater increase in overground walking endurance was achieved after the intervention (AB group mean, 72.2m; confidence interval [CI], 39.8-104.6m; BA group mean, 63.8m; CI, -10.2 to 137.9m), as compared with after standard PT (AB group mean, 38.4m; CI, 1.8-75.0m; BA group mean, 60.1m; CI, 9.2-110.9m). A similar pattern was observed for overground walking speed.
                This pilot study indicated that PWB supported treadmill training with FES had a positive effect on overground gait parameters and could potentially accelerate gait training in subjects with incomplete SCI. A larger randomized trial is required to substantiate these findings. To compare the efficacy of step training with body weight support on a treadmill (BWSTT) with over-ground practice to the efficacy of a defined over-ground mobility therapy (CONT) in patients with incomplete spinal cord injury (SCI) admitted for inpatient rehabilitation.
                A total of 146 subjects from six regional centers within 8 weeks of SCI were entered in a single-blinded, multicenter, randomized clinical trial (MRCT). Subjects were graded on the American Spinal Injury Association Impairment Scale (ASIA) as B, C, or D with levels from C5 to L3 and had a Functional Independence Measure for locomotion (FIM-L) score < 4. They received 12 weeks of equal time of BWSTT or CONT. Primary outcomes were FIM-L for ASIA B and C subjects and walking speed for ASIA C and D subjects 6 months after SCI.
                No significant differences were found at entry between treatment groups or at 6 months for FIM-L (n = 108) or walking speed and distance (n = 72). In the upper motor neuron (UMN) subjects, 35% of ASIA B, 92% of ASIA C, and all ASIA D subjects walked independently. Velocities for UMN ASIA C and D subjects were not significantly different for BWSTT (1.1 +/- 0.6 m/s, n = 30) and CONT (1.1 +/- 0.7, n = 25) groups.
                The physical therapy strategies of body weight support on a treadmill and defined overground mobility therapy did not produce different outcomes. This finding was partly due to the unexpectedly high percentage of American Spinal Injury Association C subjects who achieved functional walking speeds, irrespective of treatment. The results provide new insight into disability after incomplete spinal cord injury and affirm the importance of the multicenter, randomized clinical trial to test rehabilitation strategies. The objective of this study was to compare the effects of conventional over-ground gait training with treadmill training on the restoration of gait in people with hemiparesis following a stroke. Twenty-five individuals in the early stages of rehabilitation were alternately assigned to one of two treatment groups. In addition to conventional physical therapy, the experimental group participated in 15 treadmill-training sessions in which a handrail was used for external support. The control group received the same number of equal length sessions of over-ground ambulation. Treatment effects were established by pre- and posttreatment assessment of: 1) functional walking ability, 2) walking speed, 3) stride length, 4) temporal characteristics of gait, and 5) electromyographic activity of calf muscles. Normal values were obtained from eight healthy individuals of approximately the same age as the stroke survivors. The study demonstrates that individuals following a stroke are well able to tolerate treadmill training in the early stage of their rehabilitation process without the use of a weight support apparatus. Furthermore, the findings suggest that treadmill training may be more effective than conventional gait training for improving some gait parameters such as functional ambulation, stride length, percentage of paretic single stance period, and gastrocnemius muscular activity. To investigate whether gait training with treadmill improves functional tasks of lower extremities in patients with Parkinson disease (PD).
                Randomized controlled trial including two groups, the treadmill training group and the nonintervention group.
                University hospital.
                Thirty consecutive patients diagnosed with idiopathic PD, who were on stable regimens of antiparkinsonian medication, able to walk independently, and had not participated in a rehabilitation program in the previous 3 months. Patients with severe cognitive impairments or severe musculoskeletal, cardiopulmonary, neurologic, or other systemic disorders were excluded. Twenty-four patients completed the study.
                Group I attended a training program on a treadmill for 6 weeks, and group II served as the control group. Both groups were instructed in home mobility exercises.
                The primary study outcome measures were timed functional lower-extremity tasks (walking at a corridor, U-turn, turning around a chair, stairs, standing on one foot, standing from a chair), and secondary outcome measures were exercise test and patient's global assessment. Assessments were performed at baseline and at the end of the study.
                There were significant improvements in functional lower-extremity tests, exercise test parameters, and patients' global assessment in group I, whereas no significant improvements were observed in group II.
                Even though long-term effects remain unknown and the study sample was small, it was concluded that treadmill training in PD patients led to improvements in lower-extremity tasks, thus improving patients' physical well-being in daily life. To examine the effect of treadmill training with body weight support (TBWS) on gait and gross motor function in children with spastic cerebral palsy (CP).
                Eight children with spastic CP participated in the study. Their temporal-distance gait parameters, Gross Motor Function Measure, muscle tone, and selective motor control were assessed three times: two times under their regular therapeutic treatment (condition A), and one time after receiving the TBWS treatment in addition to their regular therapeutic treatments (condition B). There were two treatment schedules, AAB and ABA. Except for the first one (taken at study entry), the assessments were always taken after 12 wks of treatment. The children were equally divided into two groups and randomly assigned to the two schedules. The two groups were matched according to category of the Gross Motor Function Classification System.
                The TBWS treatment significantly improved the children's gait (increases in stride length and decreases in double-limb support percentage of gait cycle) and their Gross Motor Function Measure (dimension D and E scores as well as the total score). No significant improvements on muscle tone or selective motor control were noted.
                The TBWS treatment improved some gait parameters and gross motor functions in children with spastic CP.
Overall no statistically significant effect of treadmill training with or without body weight support was detected. Although individual studies suggested that treadmill training with body weight support may be more effective than treadmill training alone and that treadmill training plus task-oriented exercise may be more effective than sham exercises, further trials are required to confirm these findings.
