The Effect of Simultaneous Antigravity Treadmill Training and Electrical Muscle Stimulation After Total Hip Arthroplasty: Short Follow-Up Time
Yukio Mikami, Naoya Orita, Takuma Yamasaki, Yoshiichiro Kamijo, Hiroaki Kimura, Nobuo Adachi
Ann Rehabil Med 2019;43(4):474-482.   Published online August 31, 2019
DOI: https://doi.org/10.5535/arm.2019.43.4.474
Objective
To assess the effectiveness of our devised hybrid physiotherapy regime using an anti-gravity treadmill and a low-frequency electrical stimulation device, as measured in patients with hip osteoarthritis after total hip arthroplasty (THA).
Methods
The outcomes of the postoperative rehabilitation in 44 patients who underwent THA for hip osteoarthritis were retrospectively examined. The conventional group (n=22) underwent the postoperative rehabilitation according to our protocol, while the hybrid group (n=22) underwent the same training, along with training on an anti-gravity treadmill and training using a low-frequency therapeutic device. The outcome measures were recorded and reviewed with the Numerical Rating Scale for pain, which rates pain on an 11-point scale from 0 to 10, surgical side knee joint extension force, 10-m walking test, Timed Up and Go test, and the 6-minute walking distance (6MD). The outcome measurement was taken 2 weeks after conducting pre-operation and antigravity treadmill training and electrical muscle stimulation, and compared the respective results.
Results
At the timeframe of 2 weeks from the surgery after conducting a devised hybrid physiotherapy, the values of knee extension muscle strength and 6MD were not worse in the hybrid group than conventional group. In the evaluation at 2 weeks after surgery, the knee extension muscle strength and 6MD values significantly decreased compared with the preoperative values only in the conventional group.
Conclusion
Lower limb muscular strength and endurance were maintained in the hybrid group, which suggested that hybrid physiotherapy could maintain physical functions early after THA operation.

Effects of Low and High Frequency Needle Transcutaneous Electrical Nerve Stimulation on Pain Threshold in Normal Adults.
Kim, Sang Beom , Yoon, Kisung , Kwak, Hyun , Ha, Nam Jin , Lee, Yong Eon
J Korean Acad Rehabil Med 1999;23(3):636-642.

Objective: This study was conducted to compare the effects of low frequency needle transcutaneous electrical nerve stimulation (TENS) and high frequency needle TENS on experimental pain threshold.

Method: Twenty two healthy adult subjects were assigned randomly to a low-TENS group or to a high-TENS group. Experimental pain threshold at forearm was determined with pain threshold of electrical simulation using surface electrode and needle electrode.

Results: Low-TENS group showed that pain relief was developed after 10 minutes and persisted 3 hours after treatment cessation. Low-TENS group showed a significant increase in experimental pain threshold opposing to high TENS group.

Conclusion: This results suggest that effect of low frequency needle TENS therapy is better and longer than high frequency needle TENS therapy.

The Effect of Intramuscular Low Frequency Electrical Stimulation for Hemiplegic Shoulder Pain.
Sung, Sang Yoon , Kim, Don Kyu , Seo, Kyung Mook , Kang, Si Hyun , Park, Heon Jong
J Korean Acad Rehabil Med 2008;32(5):518-526.
Objective: To investigate the effects of intramuscular low frequency electrical stimulation on shoulder pain in hemiplegic patients. Method: Twenty five hemiplegic shoulder pain patients were divided into two groups. For experimental group, we inserted stainless steel acupuncture needle on the motor points of supraspinatus, infraspinatus, trapezius and middle deltoid muscle and applied intramuscular electric stimulation (4 Hz, unsymmetric spike pulse, 2.0 ms of pulse width) for twenty minutes, three sessions a week, in total 10 sessions. For control group, we applied transcutaneous electrical nerve stimulation for twenty minutes. Visual analog scale(VAS), passive range of motion of shoulder joint, and Korean version of modified Barthel index (K-MBI) were measured before and after the treatment. Results: The VAS of experimental group significantly decreased from 7.23±0.83 to 3.04±1.52, while control group showed a slight decrease from 7.50±0.70 to 5.64±0.74. The experimental group showed significant improvement compared to the control group (p<0.05). In the experimental group, there were significant improvements in motion of abduction from 103.6±20.5 to 134.0±32.3 and external rotation from 60.0±19.6 to 68.6±19.7 (p<0.05) even though there were no significant differences between the two groups. Conclusion: Intramuscular low frequency electrical stimulation improved pain as well as the range of motion. This could be used for the treatment of hemiplegic shoulder pain.
