Development of active myofascial trigger points in neck and shoulder musculature is similar after lumpectomy or mastectomy surgery for breast cancer.

Our aim was to describe the differences in the presence of myofascial trigger points (TrPs) in neck and shoulder muscles after 2 surgery approaches for breast cancer: mastectomy or lumpectomy. Thirty-two women (mean age: 50 ± 7 years) who received lumpectomy, 16 women (mean age: 48 ± 10 years) who had received mastectomy after breast cancer, and 16 women (mean age: 49 ± 9 years) with breast cancer who had not received either surgical treatment, participated. Myofascial TrPs in the upper trapezius, sternocleidomastoid, levator scapulae, scalene, infraspinatus and pectoralis major muscles were bilaterally explored by an assessor blinded to the women's condition. TrPs were considered active when palpation reproduced local and referred pain symptoms recognized by the patient as familiar pain symptoms. The number of active TrPs within mastectomy (mean ± SD: 4.6 ± 1) and lumpectomy (mean ± SD: 4.5 ± 1) groups was significantly higher (P < 0.001) as compared to the control group (mean ± SD: 1.1 ± 1.3), but not significantly different between them (P = 0.641). Women who received either lumpectomy or mastectomy showed similar distribution of active TrPs and a higher prevalence of active TrPs as compared to the control group. Active TrPs in the pectoralis major muscle were the most prevalent in both surgery groups The number of active TrPs was weakly correlated with neck (r(s) = 0.385; P = 0.029) and shoulder/axillary (r(s) = 0.397; P = 0.024) pain intensity within the lumpectomy, but not the mastectomy group. This study found active TrPs in neck and shoulder musculature in women who had received lumpectomy or mastectomy. The induced local and referred pain pattern from active TrPs reproduced neck and shoulder/axillary symptoms and pain patterns in women after breast cancer surgery. Few active TrPs were found in a control group of women with breast cancer who had not received any surgical treatment.

Effectiveness of a multidimensional physical therapy program on pain, pressure hypersensitivity, and trigger points in breast cancer survivors: a randomized controlled clinical trial.

OBJECTIVE: To evaluate the effects of an 8-week multidimensional physical therapy program, including strengthening exercises and recovery massage, on neck and shoulder pain, pressure hypersensitivity, and the presence of active trigger points (TrPs) in breast cancer survivors. METHODS: In this randomized controlled clinical trial, 44 breast cancer survivors were randomly assigned into 2 groups: CUIDATE group who received a multidimensional physical therapy program; or CONTROL group who received usual care treatment for breast cancer. CUIDATE program consisted of 24 hours of individual physical training (aerobic, mobility, stretching, and strengthening exercises) and 12 hours of physical therapy recovery (stretching, massage) interventions (3 times/wk, 90 min). Outcomes included neck and shoulder pain (visual analog scale, 0 to 100), pressure pain thresholds over the C5-C6 zygapophyseal joints, deltoid muscles, second metacarpal and tibialis anterior muscles, and the presence of active TrPs in shoulder muscles. Outcomes were assessed at baseline and after the 8-week program by a blinded assessor. RESULTS: The CUIDATE group showed an estimated improvement for neck pain of -56 mm [95% confidence interval (CI), -71--40, P<0.001; effect size 2.72, 1.94 to 3.44] and for shoulder/axillary of -56 mm (95% CI, -74--38, P<0.001; effect size 2.45, 1.66 to 3.23). Improvements were also noted for pressure pain thresholds levels: C5-C6 zygapophyseal joints (between-group differences 101 kPa, 95% CI, 60-143; effect size 1.68, 1.00 to 2.35; 92 kPa 55 to 129; d: 1.98, 1.18 to 2.77), deltoid muscles (98 kPa, 45 to 149; d: 1.34, 0.62 to 2.04; 75 kPa 18 to 132; d: 1.12, 0.27 to 1.96), second metacarpal (93 kPa, 45 to 134; d: 1.30, 0.63 to 1.86; 99 kPa 59 to 139; d: 1.60, 0.96 to 2.24), and tibialis anterior muscles (71 kPa, 40 to 144; d: 1.16, 0.65 to 2.34; 118 kPa 57 to 178; d: 1.17, 0.56 to 1.77). Finally, patients within the CUIDATE program showed a greater reduction of active muscle TrPs compared with the CONTROL group (P<0.01). CONCLUSIONS: An 8-week multidimensional program including strengthening exercises, and massage as major components was effective for improving neck and shoulder pain and reducing widespread pressure hyperalgesia in breast cancer survivors compared with usual care treatment.

Effectiveness of core stability exercises and recovery myofascial release massage on fatigue in breast cancer survivors: a randomized controlled clinical trial.

The purpose of the present paper was to evaluate the effects of an 8-week multimodal program focused on core stability exercises and recovery massage with DVD support for a 6-month period in physical and psychological outcomes in breast cancer survivors. A randomized controlled clinical trial was performed. Seventy-eight (n = 78) breast cancer survivors were assigned to experimental (core stability exercises plus massage-myofascial release) and control (usual health care) groups. The intervention period was 8 weeks. Mood state, fatigue, trunk curl endurance, and leg strength were determined at baseline, after the last treatment session, and at 6 months of followup. Immediately after treatment and at 6 months, fatigue, mood state, trunk curl endurance, and leg strength exhibited greater improvement within the experimental group compared to placebo group. This paper showed that a multimodal program focused on core stability exercises and massage reduced fatigue, tension, depression, and improved vigor and muscle strength after intervention and 6 months after discharge.
