Sit-to-stand is a fundamental movement of human being for performing mobility and
independent activity. However, Stroke people symptoms experience difficulty in
conducting the sit-to-stand due to paralysis and especially ankle spasticity. Recently, transcutaneouselectrical- stimulation (TENS) is used to reduce pain but
also to manage spasticity.
The purpose of this study was to determine (1) whether
TENS would lead to ankle spasticity reduction and (2) whether sit-to-stand
training combined with TENS would improve spasticity, muscle strength and balance
ability in stroke patients. Forty-stroke patients were recruited and were
randomly divided into two groups: TENS group (n=20) and sham group (n=20). All
participants underwent 30-sessions of sit-to-stand training (for 15-min,
five-times per week for 6-weeks). Prior to each training session, 30-min of TENS
over the peroneal nerve was given in TENS group, whereas sham group received
non-electrically stimulated TENS for the same amount of time.
Composite-Spasticity-Score was used to assess spasticity level of ankle
plantar-flexors. Isometric strength in the extensor of hip, knee and ankle were
measured by handheld dynamometer. Postural-sway distance was measured using a
force platform. The spasticity score in the TENS group (2.6+/-0.8) improved
significantly greater than the sham group (0.7+/-0.8, p<0.05). The muscle
strength of hip extensor in the TENS group (2.7+/-1.1kg) was significantly higher
than the sham group (1.0+/-0.8kg, p<0.05). Significant improvement in
postural-sway was observed in the TENS group compared to the sham group (p<0.05).
Thus, sit-to-stand training combined with TENS may be used to improve the
spasticity, balance function and muscle strength in stroke patients.
