- •The effect of sit-to-stand training combined with TENS was evaluated in stroke patients with spastic plantar flexor.
- •TENS followed by sit-to-stand training may improve spasticity, muscle strength and balance.
- •Clinician should consider TENS application prior to sit to stand training for stroke patients with spastic plantar flexor.
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, transcutaneous electrical- stimulation (TENS) is used to reduce pain but also to manage spasticity.
The purpose of this study was to determine
- whether TENS would lead to ankle spasticity reduction and (
- 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-minutes, five-times per week for 6-weeks). Prior to each training session, 30-minutes 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 handhelddynamometer. 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 ± 1.1 kg) was significantly higher than the sham group (1.0 ± 0.8 kg, 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.
