The efficacy and safety of dry cupping in cervical spondylosis with optimization of cup application time – A randomized clinical trial

Objectives
Dry cupping therapy (DCT) is considered beneficial in the amelioration of cervical spondylosis (CS) symptoms in Unani medicine. Therefore, the focus of this study was to ascertain the efficacy of DCT and optimal cup application time duration for CS.

Methods
It was a randomized clinical trial involving 45 participants with clinically diagnosed CS. The eligible subjects were randomly categorized into three groups, each having 15 participants. Each of the three groups, i.e., A, B, and C, received DCT daily for 15 days for 8 min, 10 min, and 12 min, respectively. All the participants were evaluated at the baseline, 7th, and 15th days of the trial using the neck disability index (NDI) as well as the visual analogue scale (VAS).

Results
The baseline mean ± SD of NDI and VAS scores were significantly reduced in all the three groups at the end of the trial. Although all three groups were statistically equal in terms of NDI, group-C demonstrated greater efficacy in terms of VAS.

Conclusions
The per-protocol analysis showed that dry cupping effectively alleviated neck pain across all treatment groups. Although, this effect on neck disability index was statistically equal in all three groups, the 12-min protocol was more successful in reducing pain.
