Evidence - WTT - STS Flashcards
1
Q
Nuzik et al, 1986
A
- Healthy population STS kinematics
- movement duration for standing up - 1.5 s
- COM moves in 2 phases: horizontal then vertical
- ankles at 15 deg DF, thigh off at 30% mvmt, knees move forward then back to start postion
2
Q
Shepherd and Gentile, 1994 found…
A
- compared active trunk inclination vs no trunk inclination
- at thigh off force through feet is 150% BW
- max force in all mm had to be sustained over a longer period of time when no forward trunk inclination
- Clinical implications: 75% BW loading required through each foot. Poor trunk inclination reduces mvmt efficiency
3
Q
Khemiani et al, 1998
A
- Ankle DF are active before the mvmt begins
- mm that propel body upward active before thighs off
- Clinical implications: whole task training engages multiple muscle groups at different times
4
Q
Shepherd and Koh, 1996
A
- Examined 3 foot positions
- further the feet are forward the greater distance body mass needs to move, movement time increases, hip moment increase, knee and ankle moments decrease
- Clinical implications: Feet too far forward = inefficient mvmt pattern
5
Q
Brunt et al, 2002
A
- Effects of 3 different foot positions: normal, unaffected extended and unaffected elevated in stroke pts
- Peak vertical force trhough affected foot greater when unaffeced foot forward and elevated. Rate of development of force greater in affected foot when unaffected foot forward or elevated
- Place unaffected foot forward, or elevate to increase loading on affected leg
6
Q
Arborelius et al, 1992
A
Examined effects of standing up in different conitions
- seat at knee height, seat at knee height with use of arms, seat at knee height & 1/3 thigh length, seat at knee height & 2/3 thigh length
- movements aroun knee and hip decrease as seat height increased
- muscle activity decrease
7
Q
Pollack et al, 2014
A
- Systematic review of 13 studies looking at the effect of interventions training STS in people with stroke.
- repetitive STS practice
- 30-60 min sessions, 3.5 x per week, 2-12 weeks
- STS interventions have beneficial effect on time take to STS and lateral symmetry during STS
- Improvements maintained at follow up
- Clinical implications: STS X’s improve wt distribution and improve task ability
8
Q
Engardt et al, 1993
A
- trainined standing up with auditory feedback. 45 mins, 5 days/ week 6 weeks
- improvement in WI, distribution both standing up and sitting down (13% compared with 5%)
9
Q
Stanton et al, 2017
A
- Review of RCT looking at effect of biofeedback on low limb activities after stroke
- biofeedback and physio tended to improve standing up more than physio alone
- Clinical implications: include feedback in treatment
10
Q
Stanton et al, 2016
A
- Feasibility of using square rule to provide feedback on foot position in prep for standing up. No verbal feedback provided
- Participants were able to stand up more quickly, with improved quality
- Clinical implications: Square rule effective for training STS
