Brief Summary

Osteoarthritis of the knee is a common degenerative joint disorder in our ageing population. A combination of thermal therapy with a self-management exercise have shown a positive effect in the management of osteoarthritis of the knee. This study aimed to compare the effectiveness of topical heat pack versus focal application of heat therapy at the acupressure points in the treatment of osteoarthritis of the knee.

Outcome Measures

Primary Outcomes (10)

  • Visual analogue scale (VAS) for pain

    10-scale likert scale to measure pain level visually; Minimum = 0 and Maximum value = 10, and higher scores mean a better outcome.

    Baseline

  • Visual analogue scale (VAS) for pain

    10-scale likert scale to measure pain level visually; Minimum = 0 and Maximum value = 10, and higher scores mean a better outcome.

    After 1 year

  • Knee range of movement (ROM)

    Knee range of movement (ROM) in the supine position using a goniometer; Numeric

Study Arms (2)

Thermal Gun group

EXPERIMENTAL

The thermal gun applied on acupressure points in TCM. The thermal gun used a heat-generating ceramic head to apply a dual effect called "heat-and-light-pressure" on the acupuncture points.

Device: Thermal gun

Heat Pack group

ACTIVE COMPARATOR

A hydrocollator heat pack used to simulate traditional thermal therapy. The application of the heat pack was wrapped with six layers of terry towels to bring the temperature down to around 43°C.

Other: Heat pack

Interventions
