Sitting training early after stroke improves sitting ability and quality and carries over to standing up but not to walking: a randomised trial.

QUESTION: What is the effect of a sitting training protocol in people early after stroke on sitting ability and quality, and does it carry over to mobility? DESIGN: Randomised placebo-controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis. PARTICIPANTS: Twelve individuals who had a stroke less than three months previously and were able to sit unsupported. INTERVENTION: The experimental group completed a 2-week sitting training protocol that involved practising reaching tasks beyond arm's length. The control group completed a 2-week sham sitting training protocol that involved practising cognitive-manipulative tasks within arm's length. OUTCOME MEASURES: The primary outcome was sitting ability (maximum reach distance). Secondary outcomes were sitting quality (reach movement time and peak vertical force through affected foot during reaching) and carry over to mobility (peak vertical force through affected foot during standing up and walking speed during 10 m Walk Test). Outcome measures were taken before and after training and six months later. RESULTS: After 2 weeks' training, the experimental group had increased their maximum reach distance by 0.17 m (95% CI 0.12 to 0.21), decreased their movement time by 0.5 s (95% CI -0.8 to -0.2), increased their peak vertical force through the affected foot during reaching by 13% of body weight (95% CI 6 to 20) and increased their peak vertical force through the affected foot during standing up by 21% of body weight (95% CI 14 to 28) compared with the control group. After 6 months, significant between-group differences were maintained for maximum reach distance and peak vertical force through the affected foot during standing up. CONCLUSIONS: The sitting training protocol was both feasible and effective in improving sitting and standing up early after stroke and somewhat effective six months later.

Group exercise can improve participants' mobility in an outpatient rehabilitation setting: a randomized controlled trial.

OBJECTIVE: To establish the effects of group exercise on mobility and strength. DESIGN: Randomized controlled trial. SETTING: Two public hospital outpatient rehabilitation services. PARTICIPANTS: One hundred and seventy-three people (mean age 74.9 years, SD 10.8) with impaired mobility were randomized and 159 people (92%) completed the trial. INTERVENTIONS: Five-week, twice-weekly ;circuit-style' group exercise programme run by a physiotherapist (n = 85) and a no-intervention waiting list control group (n = 88). MAIN OUTCOME MEASURES: Three aspects of mobility: balance while standing and stepping (Step Test, semi-tandem and tandem stance times); sit-to-stand ability (rate and minimum height) and gait (6-metre and 6-minute walk tests). Lower limb muscle strength (knee flexion and extension). RESULTS: At retest, exercise participants had improved significantly more than their control counterparts on measures of balance while stepping, sit to stand and gait. Exercise participants averaged 1.6 more steps on the 15-second Step Test (95% confidence interval (CI) 0.5 to 2.8, P=0.005), walked an average of 0.12 m/s faster (95% CI 0.05 to 0.2, P=0.002) and took 2.5 fewer steps in 6 metres (95% CI -4.2 to -0.8, P=0.004). Exercise participants also averaged 0.04 more sit-to-stands/second, (95% CI 0.003 to 0.08, P=0.037) and walked an average of 30.9 metres further in 6 minutes (95% CI 9.4 to 52.4, P=0.005). There were no clinically important or statistically significant between-group differences at retest for the measures of strength (knee extension and flexion), balance while standing or minimal sit-to-stand height. CONCLUSION: This short-duration circuit class programme improved mobility, but not strength.

A treadmill and overground walking program improves walking in persons residing in the community after stroke: a placebo-controlled, randomized trial.

OBJECTIVE: To evaluate the effectiveness of a treadmill and overground walking program in reducing the disability and handicap associated with poor walking performance after stroke. DESIGN: Randomized, placebo-controlled clinical trial with a 3-month follow-up. SETTING: General community. PARTICIPANTS: A volunteer sample of 29 ambulatory individuals (less 2 dropouts) who were living in the community after having suffered a stroke more than 6 months previously. INTERVENTIONS: The experimental group participated in a 30-minute treadmill and overground walking program, 3 times a week for 4 weeks. The control group received a placebo consisting of a low-intensity, home exercise program and regular telephone contact. MAIN OUTCOME MEASURES: Walking speed (over 10 m), walking capacity (distance over 6 min), and handicap (stroke-adapted 30-item version of the Sickness Impact Profile) measured by a blinded assessor. RESULTS: The 4-week treadmill and overground walking program significantly increased walking speed (P=.02) and walking capacity (P<.001), but did not decrease handicap (P=.85) compared with the placebo program. These gains were largely maintained 3 months after the cessation of training (P
