Considering that over ground is the commonly surface used for walking, it would be important to compare the use of a BWS system on treadmill and over ground. Aim: To analyze healthy adults walking with no harness and with 30% BWS on treadmill and over ground. Method: Kinematics data from 14 healthy adults (26 ± 3 years old) were acquired as they walked with 30% BWS and with no harness over ground and on treadmill. From these data, temporal-spatial walking parameters and joint and segmental angles were calculated. Results: Several parameter of walking over ground and on treadmill were different and the effects of partial BWS depended on the type of surface the participants walked. In general, walking over ground was characterized by faster and longer strides and with larger body segments excursion compared to walking on treadmill. ...

Objectives To determine if thoracic spinal manipulative therapy (SMT) alters thoracic kinematics, thoracic excursion, and scapular kinematics compared to a sham-SMT in patients with subacromial pain syndrome, and also to compare changes in patient-reported outcomes between treatment groups. Background Prior studies indicate that thoracic SMT can improve pain and disability in individuals with subacromial pain syndrome. However, the mechanisms underlying these benefits are not well understood. Methods Participants with shoulder impingement symptoms (n=52) were randomly assigned to receive a single session of thoracic SMT or sham-SMT. Thoracic and scapular kinematics during active arm elevation and overall thoracic excursion were measured before and after the intervention. Patient-reported outcomes measured were: pain (numeric pain rating scale [NPRS]), function (Pennsylvania Shoulder Score [Penn]), and global rating of change (GROC). Results ...

Sixteen men with ACL reconstructed (ACLr) whose torque and the gait were evaluated, before and after 12 weeks of IET, was compared to a control group (14 individuals). Student t, MANOVA and ANOVA tests were performed with 5% of significance. The training increased the isometric, concentric at 30 and 120º/s (p < .05) and eccentric at 30º/s (p < .01) extensor torque on the affected limb (AL), and eccentric at 30 and 120º/s (p < .01), on the non-affected limb (NAL). In the flexors, there was an increase on the torque: isometric, concentric at 30º/s and eccentric at 30 and 120º/s (p < .01) in AL and in eccentric at 30 (p < .05) and 120º/s (p< .01) in NAL.

Seventy one individuals, divided into 3 groups, were analyzed: young group (YG: 22.2 ± 2.1 years), middle aged group (MAG: 50.7 ± 5.7 years) and older individuals group (EG: 66.8 ± 5.4 years). Their balance was tested on a force platform, under 3 support and 3 visual conditions. Measures included: total (TD), anterior-posterior (APD) and mediolateral displacement (MLD) of the center of pressure (CoP). ANOVA revealed significant differences for interactions between group X support conditions and group X visual conditions for the 3 variables (p<0.01), with greater displacements for the MAG and EG groups during single-leg stance with partial and occluded vision (p<0.05). Static postural balance decreased over time in healthy individuals, and conditions of support and visual negatively affected balance with the increment of age.

This study investigated the effects of gait training on ground level with partial BWS in individuals with stroke during overground walking with no BWS. Methods Twelve individuals with chronic stroke (53.17 ± 7.52 years old) participated of a gait training program with BWS during overground walking, and were evaluated before and after the gait training period. In both evaluations, individuals were videotaped walking at a self-selected comfortable speed with no BWS. Measurements were obtained for mean walking speed, step length, stride length and speed, toe-clearance, durations of total double stance and single-limb support, and minimum and maximum foot, shank, thigh, and trunk segmental angles. Results After gait training, individuals walked faster, ...

Considering that ground level is the most common locomotion surface and that there is little information about individuals with stroke walking with BWS on ground level, it is important to investigate the use of BWS on ground level in these individuals as a possible alternative strategy for gait training. Methods Thirteen individuals with chronic stroke (four women and nine men; mean age 54.46 years) were videotaped walking on ground level in three experimental conditions: with no harness, with harness bearing full body weight, and with harness bearing 30% of full body weight. Measurements were recorded for mean walking speed, cadence, stride length, stride speed, durations of initial and terminal double stance, single limb support, swing period, and range of motion of ankle, knee, and hip joints; and foot, shank, thigh, and trunk segments.

Measurements were obtained for mean walking speed, step length, stride length and speed, toe-clearance, durations of total double stance and single-limb support, and minimum and maximum foot, shank, thigh, and trunk segmental angles. Results: After gait training, individuals walked faster, with symmetrical steps, longer and faster strides, and increased toe-clearance. Also, they displayed increased rotation of foot, shank, thigh, and trunk segmental angles on both sides of the body. However, the duration of single-limb support remained asymmetrical between each side of the body after gait training.

A validated sham comparator is needed to ascertain the unique effects of SMT. We investigated the plausibility of a thoracic sham-SMT comparator for SMT in patients with shoulder pain. Participants (n = 56) with subacromial impingement syndrome were randomized to thoracic SMT or a sham-SMT. An examiner blinded to group assignment took measures pre- and post-treatment of shoulder active range of motion (AROM) and perceived effects of the assigned intervention. Treatment consisted of six upper, middle and lower thoracic SMT or sham-SMT. The sham-SMT was identical to the SMT, except no thrust was applied. Believability as an active treatment was measured post-treatment. Believability as an active treatment was not different between groups (χ(2) = 2.19; p = 0.15). Perceptions of effects were not different between groups at pre-treatment (t = 0.12; p = 0.90) or post-treatment (t = 0.40; p = 0.69), and demonstrated equivalency with 95% confidence between groups at pre- and post-treatment. There was no significant change in shoulder flexion in either group over time, or in the sham-SMT for internal rotation (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; 0.05). The SMT group had an increase of 6.49° in internal rotation over time (p = 0.04). The thoracic sham-SMT of this study is a plausible comparator for SMT in patients with shoulder pain. The sham-SMT was believable as an active treatment, perceived as having equal beneficial effects both when verbally described and after familiarization with the treatment, and has an inert effect on shoulder AROM. This comparator can be considered for used in clinical trials investigating thoracic SMT. IRB number: HM 13182.
