NCT03864770

Brief Summary

Nocturnal leg cramps (NLCs) are often described as a symptom of sudden and involuntary muscle contraction at night, which often affects sleep quality due to pain and tight discomfort in the thigh, calf and foot. The investigator performed extracorporeal shock wave therapy (ESWT). This experiment used a randomized experiment to assess the immediate, short-term and long-term effects of extracorporeal shock wave therapy on patients with nocturnal leg cramps.

Outcome Measures

Primary Outcomes (1)

  • The frequency of nocturnal leg cramps (FC)

    Ask participants to describe the frequency of nocturnal leg cramps (NLCs) in the last week. The frequency of occurrence is recorded on an average of several times a day (times/day). The frequency of nocturnal leg cramps (FC) can be used as a tracking and indicator of treatment.

    1 day

Secondary Outcomes (5)

  • Visual Analog Scales (VAS)

    1 day

  • Pressure Pain Threshold (PPT)

    1 day

  • Range of Motion of knee and ankle joint

    1 day

  • Muscle tone

    1 day

  • Pittsburgh sleep quality index (PSQI)

Study Arms (2)

Extracorporeal shock wave therapy and general physical therapy

EXPERIMENTAL

In this arm, the subjects will receive the intervention of extracorporeal shock wave therapy and general physical therapy 3 times a week for 2 weeks, in total 6 times treatments and will be arrange to take efficacy two assessment on 1 week and 2 weeks after 6 times treatments separately.

Device: Extracorporeal shock wave therapyProcedure: General physical therapy

Only general physical therapy

ACTIVE COMPARATOR

In this arm, the subjects will only receive the intervention of general physical therapy 3 times a week for 2 weeks, in total 6 times treatments and will be arrange to take efficacy two assessment on 1 week and 2 weeks after 6 times treatments separately.

Procedure: General physical therapy

Interventions

Extracorporeal shock wave therapy is a mechanical sound wave that generates energy by extremely high-frequency vibration to compress the medium. Low-energy extracorporeal shock waves can be used for cell regeneration and pain control therapy; medium-high energy can be used to treat patients with poor bone healing; high-energy can be used to lithotrite. In recent years, extracorporeal shock waves have been applied on the musculoskeletal diseases, such as: epicondylitis, plantar fasciitis, chronic pelvic pain, chronic heel pain syndrome, lymphedema, burns, pressure sores, calcific tendinitis and myofascial pain syndrome. This treatment is a non-invasive and safe treatment.

Extracorporeal shock wave therapy and general physical therapy

The general physical therapies such as: thermotherapy, straight leg raise (SLR), transcutaneous electrical nerve stimulation (TENS) for treatment on calf muscle.
